Description

The processing method of carrier activation relevant information, base station and UE
Technical field
The embodiment of the present invention relates to communication technical field, relates in particular to a kind of processing method, base station and subscriber equipment (User Equipment is called for short UE) of carrier activation relevant information.
Background technology
In the LTE system, base station (Evolved Node B, be called for short eNB) and UE communicates and transfer of data.The data that the UE that is scheduled for transmits in each subframe generally comprise Physical Downlink Control Channel (the Physical Downlink Control Channel of oneself, be called for short PDCCH) signaling, this PDCCH signaling has been carried the time-frequency resource allocating information of indication physical data channel.UE carries out respective handling to PDCCH and determines the control information of oneself in the search volume, carry out further data according to this control information and process.
At the LTE of evolution (the LTE Advanced of system, abbreviation LTE-A) introduced carrier aggregation (Carrier Aggregation) technology in, namely the resource of a plurality of carrier waves can be dispatched simultaneously to a UE and use, to satisfy higher peak rate and business demand.(Radio Resource Control is controlled by semi-static Radio Resource in the base station, abbreviation RRC) signaling sends configuration information to UE, the carrier set of its required monitoring of notice UE, the carrier wave collection that UE need to monitor is called PDCCH monitoring collection (PDCCHmonitoring set), is the subset of user's downlink member carrier set (User Equipment DownlinkComponent Carrier Set).Article one, control channel is only to dispatch the transfer of data of a carrier wave, in carrier aggregation technology, UE polymerization simultaneously a plurality of carrier wave data transmissions, need many control channels.
In having adopted the LTE-A system of carrier aggregation technology, UE need to configure the data that one or more radio-frequency modules are processed a plurality of carrier waves, if a plurality of carrier waves all are in state of activation, one or more radio-frequency modules of UE need to open so, cause the UE power consumption very serious.In order to reduce the power consumption of UE, in some cases, can with some carrier wave deexcitation, make the corresponding radio-frequency module of carrier wave of UE deexcitation close.For example, in the situation that the current traffic carrying capacity of UE is less, the base station can be with some carrier wave deexcitation of UE, and the carrier wave of deexcitation is notified to UE, UE can close the corresponding radio-frequency module (if all carrier waves in UE are processed by a radio-frequency module, can not close this radio-frequency module) of carrier wave that is deactivated.In the larger situation of UE traffic carrying capacity, the base station can reactivate the carrier wave of deexcitation, and the carrier wave that reactivates is notified to UE, and UE can open the corresponding radio-frequency module of carrier wave that is reactivated.
In prior art, the base station is by sending the information that signaling is notified UE carrier activation or deexcitation to UE, and particularly, at the newly-increased bit of signaling, this newly-increased bit can represent carrier activation or deexcitation information; Perhaps use newly-increased scrambler to existing signaling scrambling, i.e. signaling after the scrambler scrambling that use increases newly is carried carrier activation or deexcitation information.
The problem that the processing method of this carrier activation of the prior art or deexcitation information exists is: added bits can be brought extra expense, and after added bits, causes the length of signaling elongated, makes the form of signaling become complicated, is unfavorable for blind Detecting.Use newly-increased scrambler can reduce existing scrambler space, simultaneously false alarm probability is had adverse effect.

Embodiment
For the purpose, technical scheme and the advantage that make the embodiment of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
Be illustrated in figure 1 as the flow chart of an embodiment of processing method of carrier activation relevant information of the present invention, comprise:
Step 101, network side obtain the carrier activation relevant information.This carrier activation relevant information comprises in carrier activation and deexcitation information at least one.
In step 101, can be specifically that the base station by network side obtains the carrier activation relevant information.The different moment, the traffic carrying capacity of certain UE is different, the base station can the traffic carrying capacity current according to UE judge needs with which carrier activation of UE, with which carrier wave deexcitation of UE, that is to say that the base station can obtain the carrier activation relevant information according to the current business amount of UE.
Step 102, network side send the PDCCH signaling to UE, these two the incompatible expression carrier activation of acquiescence redundancy group relevant information of acquiescence redundant bit in this PDCCH signaling, acquiescence redundant state or scrambler and state is so that UE processes accordingly according to the carrier activation relevant information of PDCCH denoting signaling.This step 102 specifically can be carried out by the base station of network side.
The PDCCH signaling refers to the signaling transmitted in the PDCCH channel.According to present regulation, some PDCCH signaling comprises these two acquiescence Fault-tolerant Integrated of some acquiescence redundant bits, acquiescence redundant state or scrambler and state.
The acquiescence redundant bit refer to not stipulate at present concrete implication, current system is forbidding or bit that be used for giving over to follow-up use.
The acquiescence redundant state refer at present regulation concrete meaning not, current system is forbidding or some particular states that be used for giving over to follow-up use.For example, a field A in certain PDCCH signaling comprises two bits, can comprise 4 kinds of states after these two bit padding datas so: 00,01,10,11.May stipulate at present the implication of state 00 and 11 expressions, but not have the implication of specified states 01 and 10, state 01 and 10 is exactly the state of giving tacit consent to redundancy so, and 01 or 10 can be as carrier activation or deexcitation sign.
These two acquiescence Fault-tolerant Integrated of scrambler and state refers at present the regulation concrete meaning, the current system forbidding or is used for giving over to these two the combination of the scrambler of follow-up use and state.For example, certain PDCCH signaling can be used scrambler C scrambling, certain field A in this PDCCH signaling can comprise a state S and other states, using scrambler C scrambling and field A is this combination of state S, at present do not stipulate that concrete implication, this combination are exactly a kind of combination of giving tacit consent to redundancy.
UE is after receiving the PDCCH signaling, if these two acquiescence Fault-tolerant Integrated of this class acquiescence redundant bit, acquiescence redundant state or scrambler in the PDCCH signaling and state detected, can determine to carry the carrier activation relevant information in this PDCCH signaling, thereby can determine the content that the carrier activation relevant information in the PDCCH signaling represents.
According to present regulation, the PDCCH signaling is used for transmission downlink or uplink schedule information.If carry the carrier activation relevant information in the PDCCH signaling, the PDCCH signaling just is different from the PDCCH signaling of present regulation so, other each bit or field in the PDCCH signaling of carrier activation relevant information have been carried, can be according to the demand of system, by reinterpreting to give new implication.
The processing method of the carrier activation relevant information that the embodiment of the present invention provides, these two the incompatible expression carrier activation of acquiescence redundancy group relevant information of acquiescence redundant bit in the PDCCH signaling, acquiescence redundant state or scrambler and state, need to not increase bit on the basis of existing PDCCH signaling, do not need to use newly-increased scrambler to the scrambling of existing PDCCH signaling yet, but utilized existing PDCCH signaling fully, can not cause extra expense, can not reduce the scrambler space of existing PDCCH signaling; And the processing method of the carrier activation relevant information that the embodiment of the present invention provides need not to change length or the structure that has the PDCCH signaling now, make troubles can not for the blind Detecting of PDCCH.
Be illustrated in figure 2 as the flow chart of another embodiment of processing method of carrier activation relevant information of the present invention, comprise:
Step 201, UE receive the PDCCH signaling that network side sends.
Step 202, UE resolve the PDCCH signaling.
If step 203 PDCCH signaling comprises the carrier activation relevant information that is represented by these two acquiescence Fault-tolerant Integrated of acquiescence redundant bit, acquiescence redundant state or scrambler and state, according to being set really, set pattern determines the content that the carrier activation relevant information represents.
This obtains really set pattern in advance can be pre-stored in UE, and which information is which field in can regulation PDCCH signaling in this definite rule carry, and how determines content that the carrier activation relevant information represents etc. according to the information of each field.
Step 204, UE open the radio-frequency module corresponding with the carrier wave that needs to activate and/or close the radio-frequency module corresponding with the carrier wave that needs deexcitation.
If do not comprise the carrier activation relevant information that is represented by these two acquiescence Fault-tolerant Integrated of acquiescence redundant bit, acquiescence redundant state or scrambler and state in the PDCCH signaling, according to the regulation in existing protocol, determine the control information in the PDCCH signaling.
The carrier activation that the embodiment of the present invention provides or anti-activating method, UE is after receiving the PDCCH signaling, the PDCCH signaling comprises the carrier activation relevant information that these two acquiescence Fault-tolerant Integrated of acquiescence redundant bit, acquiescence redundant state or scrambler and state represents, compared with prior art, can not cause extra expense.And, because length or the structure of the PDCCH signaling that receives do not change, make troubles can for the blind Detecting of the PDCCH of UE.
The PDCCH signaling comprises a variety of, and these two acquiescence Fault-tolerant Integrated of the acquiescence redundant bit in various PDCCH signalings, acquiescence redundant state or scrambler and state is also different.
In the system that has used carrier aggregation technology, for example in the LTE-A system (in following examples mainly take the LTE-A system as the example introduction), the granularity of carrier activation or deexcitation can vary.Roughly can comprise following two classes:
I, the whole activation or the deexcitation granularity
Under this activation or deexcitation granularity, for situation about activating, be once will be except when front n-1 the carrier wave that is in outside the state of activation carrier wave for the bearing activation signaling all activates, n is the carrier number in the set of user's downlink member carrier; For the situation of deexcitation, due to can not be with n the whole deexcitations of carrier wave, and must keep a carrier activation, so in this case, be with n-1 the whole deexcitations of carrier wave, keep a carrier activation.
II, the local activation or the deexcitation granularity
This activation or deexcitation granularity are that single carrier wave or quantity are less than or equal to the carrier wave set that the carrier wave of n-1 forms, and once can activate or the single carrier wave of deexcitation, perhaps once can activate or deexcitation quantity or equal carrier wave less than n-1.
The carrier activation relevant information refers to need to which carrier activation, need to be with the information of which carrier wave deexcitation.For I kind granularity, need not in the PDCCH signaling to comprise concrete needs activate or deexcitation be which carrier wave because need to activate or the number of carriers of deexcitation is fixedly n-1.
For II kind granularity, can comprise carrier activation and/or deexcitation content in the PDCCH signaling, need to which carrier activation to illustrate specifically, need to which carrier wave deexcitation.
For II kind granularity, in the PDCCH signaling, the bit number that is used for expression carrier activation and/or deexcitation content can equal the carrier number of LTE-A system, can equal system configuration to the set carrier number that does not rely on the set of user's downlink member carrier of UE, also can equal the carrier number in the set of user's downlink member carrier.
For example, suppose that the LTE-A system always has 5 carrier waves, and the carrier number in the set of a certain moment user downlink member carrier is wherein 3, and in the PDCCH signaling, the bit number that is used for expression carrier activation and/or deexcitation content equals the carrier number 5 of LTE-A system so.
Like this, when base station transmission RRC reshuffles the set of signaling change user downlink member carrier, can not receive RRC because of UE and reshuffle signaling, perhaps UE receives that RRC reshuffles signaling and the base station is not also received to reshuffle and completed signaling, causes UE to resolve mistakenly carrier activation that the base station sends or the PDCCH signaling of deexcitation.
In prior art, base station transmission RRC reshuffles signaling and sends to UE to change the set of user's downlink member carrier, UE is receiving that correctly RRC reshuffles signaling and will operate accordingly according to the information in signaling, but the base station only could have been determined after reshuffling of receiving that UE sends completed signaling the configuration successful of UE.That is to say, within the interval time of two signalings, the base station can't determine whether UE has correctly received RRC and reshuffled signaling.So, if the base station is in the situation that receive that not reshuffling that UE sends complete signaling, send the PDCCH signaling according to the user's downlink member carrier set after changing, and in fact UE does not receive that RRC reshuffles signaling, like this, UE can not resolve according to having the set of user's downlink member carrier there is no to change rule before after receiving the PDCCH signaling, can cause the UE parse error like this.For example, if the set of user's downlink member carrier is A, B, C before changing, the bit number that is used for expression carrier activation and/or deexcitation content equals 3, and these three bits represent respectively A, B and C.Become A, C, D after the set of user's downlink member carrier changes, the bit number that is used for expression carrier activation and/or deexcitation content equals 3, and these three bits represent respectively A, C and D.If UE does not receive RRC and reshuffles signaling, still resolve according to the resolution rules before changing, that UE can think that second bit represent so is carrier wave B, and in the PDCCH signaling that in fact base station sends, that be used for that second bit of the bit of expression carrier activation and/or deexcitation content represent is carrier wave C.
If the bit number that is used for expression carrier activation and/or deexcitation content in the PDCCH signaling equals the carrier number of LTE-A system, perhaps equal system configuration to UE, set carrier number that do not rely on the set of user's downlink member carrier, even the set of user's downlink member carrier changes, resolution rules before UE also can change according to the set of user's downlink member carrier parses carrier activation or the deexcitation information content, can not cause the error resolution of UE.
User's downlink member carrier set of UE is the base station to the subset of the carrier set that does not rely on the set of user's downlink member carrier of UE configuration, the base station for the configuration of each UE not rely on the set that user's downlink member carrier set separately changes can be different.
In addition, during a plurality of carrier wave of UE polymerization, can select a up-link carrier to send all upstream control signalings, can be called main carrier together with the paired descending carrier of this up-link carrier, the change of main carrier is if notify the words of UE by the RRC signaling, above-mentioned two kinds do not rely on the carrier activation of user's downlink member carrier set or the design of deexcitation signaling, can also avoid the UE main carrier to be changed by the RRC signaling and the impact that brings.
In addition, if in the PDCCH signaling, the bit number that is used for expression carrier activation and/or deexcitation content equals the carrier number 3 of user's downlink member carrier set, and the bit number that uses is less, can reduce expense.
How lower mask body introduction carries the carrier activation relevant information by various PDCCH signalings.
One, the PDCCH signaling comprises Downlink Control Information (Downlink Control Information is called for short DCI) form 0 or DCI form 1A
(1) the I kind activates or the deexcitation granularity
DCI is the signaling that is carried in PDCCH, and DCI mainly transmits descending or uplink scheduling information, perhaps uplink power control order.DCI comprises multiple format, DCI form 1A and DCI form 0 all comprise a stature differentiation bit, the Head Section of DCI form 1A divide the value of bit be the Head Section of 1, DCI form 0 to divide the value of bit be 0, this two stature is distinguished the form that bit is respectively used to identify these two DCI.
The mode that resource allocation field in DCI form 1A and DCI form 0 adopts continuous resource to distribute, resource allocation field comprises initial Resource Block (Resource Block, abbreviation RB) length of index number and the RB of distribution, the bit number N that resource allocation field needs BEqual log 2 (N * N+1)/2)Value after rounding up, wherein, N is the RB sum of system bandwidth.Resource allocation field comprises
Figure GSA00000013738600101
The state of kind, these states comprise a plurality of acquiescence redundant states, so can represent by the acquiescence redundant state of resource allocation field the first sign or the second sign, wherein the first sign is used to indicate the PDCCH signaling and comprises carrier activation information, and the second sign is used to indicate the PDCCH signaling and comprises carrier wave deexcitation information.For DCI form 0, the RB length that in existing protocol, requirement can be dispatched must be 2,3 or 5 the factor, so in the allocation field of DCI form 0, the relative form DCI of the state form 1A of acquiescence redundancy is more more.
In step 102, the PDCCH signaling can comprise DCI form 0 or DCI form 1A, wherein a kind of acquiescence redundant state of resource allocation field of DCI form represents the first sign, and a kind of Head Section of DCI form divides bit to represent the carrier activation content that carrier activation information is corresponding; The acquiescence redundant state of the resource allocation field of another kind of DCI form represents the second sign, and the Head Section of another kind of DCI form divides bit to represent the carrier wave deexcitation content that carrier wave deexcitation information is corresponding.
Which carrier wave the concrete expression of this carrier activation content has need to activate; Similarly, which carrier wave is carrier wave deexcitation contents table be shown with needs deexcitation.
Wherein, the PDCCH signaling can be DCI form 1A, and the first sign represents by the acquiescence redundant state of the resource allocation field in DCI form 1A, and the carrier activation content divides bit to represent by the Head Section in DCI form 1A.The PDCCH signaling can be that the acquiescence redundant state that DCI form 0, the second identifies by the resource allocation field in DCI form 0 represents, carrier wave deexcitation content divides bit to represent by the Head Section in DCI form 1A.
Perhaps, the PDCCH signaling can be DCI form 1A, and the second sign represents by the acquiescence redundant state of the resource allocation field in DCI form 1A, and the carrier wave district activates content and divides bit to represent by the Head Section in DCI form 1A.The PDCCH signaling can be that the acquiescence redundant state that DCI form 0, the first identifies by the resource allocation field in DCI form 0 represents, the carrier activation content divides bit to represent by the Head Section in DCI form 1A.
Because the position of the resource allocation field in DCI form 1A and DCI form 0 is different, when so the resource allocation field of these two signalings represents respectively the first sign or the second sign, need the Head Section in dependent format 1A and 0 to divide bit to represent carrier activation or deexcitation content, namely Head Section divides bit to reinterpret.Divide bit to represent carrier activation or deexcitation content with the Head Section in DCI form 1A and DCI form 0, do not need to distinguish carrier activation and these two kinds of contents of deexcitation with other bits in the PDCCH signaling or state, can save bit in the PDCCH signaling or the use expense of state.
In step 203, the PDCCH signaling comprises the carrier activation relevant information that is represented by the acquiescence Fault-tolerant Integrated of giving tacit consent to redundant bit, acquiescence redundant state or scrambler and state, specifically can comprise: the acquiescence redundant state of the resource allocation field of a kind of DCI form in DCI form 0 or DCI form 1A represents the first sign, and the acquiescence redundant state of the resource allocation field of the another kind of DCI form in DCI form 0 or DCI form 1A represents the second sign.
UE determines according to arranging really to establish rules the content that the carrier activation relevant information represents, specifically can comprise: the value that the sign that the DCI form that comprises according to the PDCCH signaling is corresponding and the Head Section of DCI form divide bit, determine the content that the carrier activation relevant information represents, wherein, the content of dividing the value of bit to determine that the carrier activation relevant information represents according to the first sign and the Head Section of DCI form is the carrier activation content, identifies and content that the Head Section of DCI form divides the value of bit to determine that the carrier activation relevant information represents is carrier wave deexcitation content according to second.
(2) the II kind activates or the deexcitation granularity
In this case, the carrier activation relevant information comprises the 3rd sign; The 3rd sign is used to indicate the PDCCH signaling and comprises at least one in carrier activation information and carrier wave deexcitation information.The PDCCH signaling comprises DCI form 1A or DCI form 0, and in DCI form 1A or DCI form 0, the acquiescence redundant state of resource allocation field represents the 3rd sign, and all the other bits except resource allocation field or field represent carrier activation and/or deexcitation content; Wherein, the corresponding carrier activation information of carrier activation content; The corresponding carrier wave deexcitation of carrier wave deexcitation content information.
Because DCI form 1A or DCI form 0 comprise the 3rd sign, so the implication of other each bit in DCI form 1A and DCI form 0 need to redefine, other bits except resource allocation field or state can carry carrier activation content and/or deexcitation content.For example, for DCI form 0 and form 1A, except resource allocation field represents the 3rd sign, can adopt other bit or field except resource allocation field to represent carrier activation and/or deexcitation content.
Can also carry CRC information in the PDCCH signaling, wherein, CRC refers to some bit is set to fixing value, as is set to " 0 ", can also carry more other information.
In step 203, the PDCCH signaling comprises the carrier activation relevant information that the acquiescence Fault-tolerant Integrated by acquiescence redundant bit, acquiescence redundant state or scrambler and state represents, specifically can comprise: DCI form 0 or DCI form 1A comprise the 3rd sign that the acquiescence redundant state by resource allocation field represents.
UE determines according to arranging really to establish rules the content that the carrier activation relevant information represents, comprise: according to other bits except resource allocation field or the value of state in the DCI form 0 of PDCCH signaling or DCI form 1A, determine the content that the carrier activation relevant information represents.
Two, the PDCCH signaling is DCI form 0 or DCI form 1A
(1) the I kind activates or the deexcitation granularity
In step 102, the carrier activation relevant information specifically comprises carrier activation information or carrier wave deexcitation information, and carrier activation information comprises the first sign, and carrier wave deexcitation information comprises the second sign; In the DCI form of PDCCH signaling, one of resource allocation field acquiescence redundant state represents the first sign, and in the DCI form, another acquiescence redundant state of resource allocation field represents the second sign; The DCI form is DCI form 0 or DCI form 1A.
That is to say, two acquiescence redundant states with resource allocation field in DCI form 0 represent the first sign and the second sign respectively.
Perhaps, under the activation of I kind or deexcitation granularity, in step 102, the carrier activation relevant information comprises the 3rd sign; In the DCI form of PDCCH signaling, one of resource allocation field acquiescence redundant state represents the 3rd sign, divides other bits or state representation carrier activation and/or deexcitation content bit except resource allocation field and Head Section in the DCI form; The DCI form is DCI form 0 or DCI form 1A.
That is to say, an acquiescence redundant state with the resource allocation field of DCI form 0 or DCI form 1A represents to carry the carrier activation relevant information in this DCI form 0 or DCI form 1A, and using what divide that another bit bit represents to carry in the PDCCH signaling except resource allocation field and Head Section is carrier activation content or carrier wave deexcitation content.
The below introduces take the former as example:
For example, if a kind of acquiescence redundant state S1 of the resource allocation field in DCI form 0 represents this sign of carrier activation, another kind of acquiescence redundant state S2 represents this sign of carrier wave deexcitation.When UE receives the PDCCH signaling, if resource allocation field is the S1 state, UE can determine to need will except when front n-1 the carrier wave that is in outside the state of activation carrier wave for the bearing activation signaling all activate.If resource allocation field is the S2 state, UE can determine and n-1 carrier wave deexcitation need to be kept a carrier activation.
In step 203, the PDCCH signaling comprises the carrier activation relevant information that is represented by the acquiescence Fault-tolerant Integrated of giving tacit consent to redundant bit, acquiescence redundant state or scrambler and state, specifically can comprise: in DCI form 0 or DCI form 1A, one of resource allocation field acquiescence redundant state represents the first sign, and another acquiescence redundant state represents the second sign;
UE determines specifically to comprise the content that described carrier activation relevant information represents according to arranging really to establish rules: determine according to an acquiescence redundant state and another acquiescence redundant state of resource allocation field in DCI form 0 or DCI form 1A the content that the carrier activation relevant information represents.
(2) the II kind activates or the deexcitation granularity
In step 102, the carrier activation relevant information comprises the 3rd sign; In the DCI form of PDCCH signaling, one of resource allocation field acquiescence redundant state represents the 3rd sign, divides other bits or state representation carrier activation and/or deexcitation content bit except resource allocation field and Head Section in the DCI form; The DCI form is DCI form 0 or DCI form 1A.
In step 203, the PDCCH signaling comprises that the carrier activation relevant information that is represented by acquiescence redundant bit, the acquiescence Fault-tolerant Integrated of acquiescence redundant state or scrambler and state specifically can comprise: DCI form 0 or DCI form 1A comprise the 3rd sign that the acquiescence redundant state by resource allocation field represents;
UE determines according to arranging really to establish rules the content that the carrier activation relevant information represents, specifically can comprise: according to dividing other bits bit or the value of field except resource allocation field and Head Section in the DCI form 0 of PDCCH signaling or DCI form 1A, determine the content that the carrier activation relevant information represents.
In DCI form 0, the acquiescence redundant state of resource allocation field is than many in DCI form 1A (because the RB number that the resource in form 0 is distributed must be 2,3,5 the factor); When system bandwidth is identical, equal in length for the signaling that keeps DCI form 1A and DCI form 0, have a filling bit in DCI form 0, adopt DCI form 0 as the PDCCH signaling that is used for carrying carrier activation or deexcitation, 1A compares with the DCI form, can further reduce false alarm probability.
Three, the PDCCH signaling is that resource distribution type is 1 or 0 PDCCH signaling, as DCI form 1, DCI form 2 or DCI form 2A etc.
The resource of PDCCH is distributed and is comprised that continuous resource is distributed and discrete resource is distributed.Distribute with bit mapping (bitmap) indication for discrete resource and distribute to the UE that is scheduled.For example, the minimum particle size that the RB of system adds up to 50, RB distribution is 3, needs the RB allocation field of 17 bits, and certain bit is 1 o'clock, illustrates that 3 corresponding RB have been assigned to UE, and this bit is 0 o'clock, illustrates that 3 corresponding RB do not distribute to UE.The resource of bit mapping mode is divided into two classes, Class1 and type 0.The bit mapping resource distribution mode of type 0 is take the RB group as unit, and the bit mapping resource distribution mode of Class1 is take RB as unit after grouping.If greater than 10 RB, having resource, system bandwidth distribute type 0 and resource to distribute the resource allocation field of the PDCCH signaling of Class1 that a type classification bit is arranged.The type is distinguished resource that bit is used for distinguishing the PDCCH signaling, and to distribute type be 0 or 1.If system bandwidth is less than or equal to 10 RB, do not need the type classification bit in the PDCCH signaling, namely Class1 and type 0 are as broad as long, because the minimum particle size that resource is distributed is 1 RB.
Activate or deexcitation granularity and the activation of II kind or deexcitation granularity for the I kind, in step 102, the carrier activation relevant information comprises the 3rd sign; The PDCCH signaling comprises that resource distribution type is 1 or 0 PDCCH signaling.
For the situation of system bandwidth greater than 10 Resource Block RB, it is full 0 state representation the 3rd sign of other bits of resource allocation field except the type classification bit in 1 or 0 PDCCH signaling that resource is distributed type, the type classification bit represents to activate and/or deexcitation content, perhaps type classification bit and other bits except resource allocation field or state representation carrier activation and/or deexcitation content.
It is full 0 state representation the 3rd sign of resource allocation field in 1 or 0 PDCCH signaling that the situation that is less than or equal to 10 RB for system bandwidth, resource are distributed type; It is other bits or state representation carrier activation and/or the deexcitation content except resource allocation field in 1 or 0 PDCCH signaling that resource is distributed type.
The PDCCH signaling is that resource distribution type is 1 or 0 DCI form 1, DCI form 2 or DCI form 2A etc.
According to existing agreement regulation, the full 0 state of other bits of resource allocation field except the type classification bit does not have concrete implication, be the state of acquiescence redundancy, i.e. representative distributes any resource to UE, be can not use in existing system and existing system in UE can not identify.
In step 203, the PDCCH signaling comprises that the carrier activation relevant information that is represented by acquiescence redundant bit, the acquiescence Fault-tolerant Integrated of acquiescence redundant state or scrambler and state specifically can comprise: it is the 3rd sign that 1 or 0 PDCCH signaling comprises the full 0 state representation of other bits of resource allocation field except the type classification bit that resource is distributed type; Perhaps, to distribute type be the 3rd sign that 1 or 0 PDCCH signaling comprises the full 0 state representation of resource allocation field to resource;
UE determines according to arranging really to establish rules the content that the carrier activation relevant information represents, specifically can comprise: distributing type according to resource is the value of type classification bit in 1 or 0 PDCCH signaling, perhaps type classification bit and other bits except resource allocation field or the value of state, perhaps the value of the bit of other except resource allocation field or state, determine the content that the carrier activation relevant information represents.
Four, the PDCCH signaling is for the PDCCH signaling that triggers random access procedure
Physical Random Access Channel order PDCCH (Physical Random Access Channelorder PDCCH, being called for short PRACH order PDCCH) signaling is the PDCCH signaling that is used for triggering random access procedure in the LTE system, is namely PRACHorder PDCCH signaling after some field in DCI form 1A is disabled.In case UE finds this disabled status, just can identify this PDCCH signaling is PRACH order PDCCH signaling, rather than common PDCCH signaling for data dispatch.These disabled status comprise: form 1A and form 0 type classification bit are set to 1, and centralized and distributed being designated sets to 0, and resource allocation field is set to the preamble index field of complete 1,6 bit, the mask index field of 4 bits, and other bits are for entirely being set to 0.The mask index field of 4 bits can comprise 16 kinds of bit combinations, and in frequency division duplex system, these 16 kinds of bit combinations comprise the Fault-tolerant Integrated of 3 kinds of acquiescences.

In step 102, the carrier activation relevant information specifically comprises carrier activation information or carrier wave deexcitation information, and carrier activation information comprises the first sign, and carrier wave deexcitation information comprises the second sign; The PDCCH signaling comprises for the PDCCH signaling that triggers random access procedure, should represent the first sign for an acquiescence redundant state of the PDCCH signaling mask index field that triggers random access procedure, and another acquiescence redundant state represents that second identifies.
That is to say, two acquiescence redundant states that are respectively used to trigger mask index field in the PDCCH signaling of random access procedure represent that the first sign and second identifies.
In step 203, the PDCCH signaling comprises the carrier activation relevant information that the acquiescence Fault-tolerant Integrated by acquiescence redundant bit, acquiescence redundant state or scrambler and state represents, specifically can comprise: the PDCCH signaling that is used for triggering random access procedure comprises the first sign or the second sign that the acquiescence redundant state by the mask index field represents.

In step 102, the carrier activation relevant information comprises the 3rd sign; In the DCI form of PDCCH signaling, the combination of the acquiescence redundant state of the acquiescence redundant state of power control field and HARQ process field or these two fields represents the 3rd sign, other bits except power control field and HARQ process field or state representation carrier activation and/or deexcitation content.
In step 203, the PDCCH signaling comprises that the carrier activation relevant information that is represented by acquiescence redundant bit, the acquiescence Fault-tolerant Integrated of acquiescence redundant state or scrambler and state specifically can comprise: use paging RNTI, system information RNTI or comprise the redundant state of acquiescence of power control field and HARQ process field with the DCI form 1A that the RNTI scrambling is replied in access or the 3rd sign that the combination of acquiescence redundant state represents;
UE determines according to set pattern is set really the content that the carrier activation relevant information represents, specifically can comprise: from using paging RNTI, system information RNTI or replying the DCI form 1A of RNTI scrambling other bits except power control field and HARQ process field with access or the value of state is determined the content that the carrier activation relevant information represents.
Seven, the PDCCH signaling is to use the PDCCH signaling of semi-continuous scheduling scrambler-residential quarter-RNTI (SPS-C-RNTI) scrambling
The opening and closing of semi-continuous scheduling (Semi-Persistent Scheduling is called for short SPS) configure by the RRC signaling, and after SPS opened, UE can detect the PDCCH signaling of SPS-C-RNTI scrambling.The PDCCH signaling of the SPS that is used for activation and reshuffles is by the SPS-C-RNTI scrambling, wherein NDI is set to 0, the fixed bit that also has 6 extra bits as virtual CRC check position (at time division duplex (Time Division Duplex, abbreviation TDD) in system, this fixed bit is 7 bits), the value of this 6 bit is fixed.For example, for DCI form 1A, under frequency division duplex system, the HARQ process field of 3 bits, the RV field of 2 bits, the highest order of 5 bit MCS fields, the value of this 6 bit is fixed as 0; Be used for the PDCCH signaling of SPS business re-transmission by the SPS-C-RNTI scrambling, wherein NDI is set to 1.

In the situation that the SPS business is closed, do not need the PDCCH signaling of SPS-C-RNTI scrambling, so the carrier activation relevant information is represented by bit or field in the PDCCH signaling of SPS-C-RNTI scrambling.All bits or field in the PDCCH signaling of SPS-C-RNTI scrambling can reinterpret.That is to say, in the situation that the SPS business is closed, the signaling of the PDCCH of SPS-C-RNTI scrambling has had the function in the situation that is different from the unlatching of SPS business.
Reuse the PDCCH signaling of SPS-C-RNTI scrambling as the signaling that is used for carrier activation or deexcitation, compare with the PDCCH signaling of C-RNTI scrambling, can reduce false alarm probability; And will use 6 virtual CRC check position states in the PDCCH signaling of SPS-C-RNTI scrambling to be inverted, can further reduce false alarm probability; Simultaneously, little with respect to the resource allocation field expense in the PDCCH signaling of utilizing the SPS-C-RNTI scrambling, the efficient that reinterprets utilization of other fields improves.
In prior art, the configuration information of UE sends to UE by the base station by semi-static RRC signaling, UE is receiving that correctly RRC connects configuration (RRC Connection Reconfiguration) signaling and will operate accordingly according to configuration information, but the base station only could have been determined after (RRC Connection Reconfiguration Complete) signaling is completed in configuration the configuration successful of UE receiving that RRC that UE sends connects.That is to say, within the time of two signalings, the base station can't determine whether UE has correctly received RRC and connected configuration signal, the base station just can't determine that also need to receive RRC according to UE connects before configuration signal the configuration parameter of UE UE is dispatched, or need to receive RRC connection configuration signal configuration information afterwards according to UE UE is dispatched, thereby can cause the base station fuzzy to the scheduling of UE.
In order to solve the fuzzy problem of above-mentioned scheduling, in the processing method of carrier activation relevant information provided by the invention, the base station sends in the PDCCH signaling of UE except can carrying the carrier activation relevant information, can also carry the configuration information of UE.In the embodiment of the present invention, carry the carrier activation relevant information in the PDCCH signaling, so can reinterpret except the bit of carrier activation relevant information or other bits state or state in the PDCCH signaling namely can be used for carrying the configuration information of these UE.
These configuration informations can comprise the transmission mode, main carrier of carrier wave change corresponding relation between the configuration information of the search volume of information, UE, PDCCH monitoring collection (PDCCH monitoring set), UE downlink member subset, PDCCH monitoring collection and UE downlink member subset, to the schedule information of carrier wave.
The below introduces respectively the carrying mode of these configuration informations in the PDCCH signaling.
(1) carry the carrier transmission pattern information in carrying the PDCCH signaling of carrier activation relevant information
Introduced the multiple PDCCH signaling that can carry the carrier activation relevant information in aforesaid embodiment, other bits in these signalings except carrying the carrier activation relevant information or state can be for the transmission mode information of carrying some carrier wave.The base station sends to UE with the PDCCH signaling, and UE can also receive the carrier transmission pattern information except receiving the carrier activation relevant information, sends separately the RRC signaling and sends the carrier transmission pattern information and need not the base station, has avoided the scheduling of base station fuzzy.
Take with carrier dispatching as example.Refer to that with carrier dispatching control channel on certain carrier wave only to dispatch the data of this carrier wave or the up-link carrier corresponding with this carrier wave, that is to say, control channel and its can data dispatching carrier wave have one-to-one relationship.under the scene with carrier dispatching, suppose to have in the set of user's downlink member carrier 2 carrier waves, form 1 under the transmission mode of carrier wave C1 and form 0/1A, form under the current transmission mode of carrier wave C2 (C2 is in deactivation status) is 2 and 0/1A, change the transmission mode of C2 and activate C2 if need, its form is changed to form 2 and 0A (supposing that the Uplink MIMO form is 0A), can carry carrier activation information this moment by the mode in previous embodiment in PDCCH, and carry transmission mode information in the PDCCH signaling, notice UE changes the pattern of C2.Like this, the base station can determine that namely UE can correctly receive this transmission mode information after issuing PDCCH, and need not to wait for that confirmation that UE returns receives the confirmation signaling of transmission mode information, after the base station issues the PDCCH signaling, in the time of need to dispatching UE, namely can dispatch to the configuration information to UE after UE according to issuing the PDCCH signaling, avoid the scheduling of base station fuzzy.
Supposing that each carrier wave is descending has seven kinds of transmission modes, up have two kinds of transmission modes, each carrier wave need to be used 3+1=4 bit at least, represents that seven kinds of descending transmission modes need at least 3 bits, represents that two kinds of up transmission modes need at least 1 bit.
At present, the fall-back mode of LTE is form 0/1A, has arrived LTE-A, if fall-back mode is variable, for example 2A is used as fall-back mode under MIMO.So dynamic signaling can 1 bit indication fall-back mode be 0 or 1A, or 2A.
(2) carry main carrier in carrying the PDCCH signaling of carrier activation relevant information and change information
Can define the specific main carrier of one or more UE (descending) for UE in the LTE-A system, the feature of this main carrier can be: the paired descending carrier of up-link carrier that is used for sending ascending control channel, perhaps public search space only detects on main carrier, etc.
Main carrier changes information and can be carried at by following mode in the PDCCH signaling:
(1) other bits except the bit that carries carrier activation relevant information and carrier activation and/or deexcitation content or state carry main carrier change information in carrying the PDCCH signaling of carrier activation relevant information.The carrier aggregation wave number of supposing the UE maximum is 5, needs at least 3 bits to carry main carrier and changes information.
(2) send the PDCCH signaling that carries the carrier activation relevant information on need to be as the carrier wave of main carrier
Suppose to have 3 carrier waves in the set of active user's downlink member carrier, the carrier wave that is in state of activation is C1 and C2, and carrier wave C3 is in deactivation status.If send the PDCCH signaling that is used for activating C3 on carrier wave C2, UE can determine that carrier wave C2 is current main carrier.
(3) carry carry scheduling in the PDCCH of carrier activation relevant information need to be as the information of the carrier wave of main carrier
Suppose to have 3 carrier waves in the set of active user's downlink member carrier, send to be used for scheduling carrier wave C2 and to carry PDCCH signaling for the information that activates carrier wave C3 on carrier wave C1, UE can determine that carrier wave C2 is the main carrier of UE.
(3) carry the configuration information of the specific search volume of UE (this search volume is different from public search space) on some carrier wave in carrying the PDCCH signaling of carrier activation relevant information, perhaps carry the configuration information of the search volume of some specific control channel form
The PDCCH blind Detecting number of times and the PDCCH that consider UE in order to compromise dispatch blocking rate, can adjust the size of PDCCH search volume.If current PDCCH scheduling blocking rate is larger, under the prerequisite that is no more than the maximum blind Detecting ability of UE, the suitable size in expanded search space; If current PDCCH scheduling blocking rate is very little, in order to reduce the PDCCH blind Detecting of UE, be the UE power saving, can suitably dwindle the size of search volume.Illustrate, two PDCCH of UE have search volume separately on a carrier wave, when the signaling length of two PDCCH does not wait, UE can be in two PDCCH search volume separately search PDCCH separately; When the signaling of two PDCCH is equal in length, two search volumes can be shared, be that UE can detect two PDCCH of this same signaling length in two search volumes, the dispatching flexibility situation that detects separately PDCCH than the separate searches space of PDCCH increases to some extent due to this moment, so can dwindle the search volume this moment, reduce the blind Detecting number of times of PDCCH, compromise between blind Detecting number of times and PDCCH scheduling blocking rate.The size in two separate searches spaces of concrete hypothesis (search volume 1 and search volume 2) is all 6 control channel unit (Control Channel Element, be called for short CCE), when the signaling length of two PDCCH does not wait, UE detects a PDCCH in search volume 1, detects the 2nd PDCCH in search volume 2; When the signaling of two PDCCH is equal in length, UE can detect a PDCCH and the 2nd PDCCH (signaling length equals the 2nd PDCCH) in whole two search volumes, can configure whole search volume size this moment for certain value less than 6*2, such as 9.
Particularly, also the search volume on each carrier wave can be divided into several ranks, for example can be divided into three ranks, be respectively search volume size and higher than search volume size in normal LTE system in the size of search volume in normal LTE system, subnormal LTE system.Need at least 2 bits to notify for each carrier wave; Also can adjust the configuration information of the search volume of certain specific control channel form, for example, change the search volume size of total form 0/1A.
Further, consider that the reliability of PDCCH signaling is not as semi-static RRC signaling, in order not interrupt the scheduling of base station in the situation that mistake appears in the transmission of PDCCH signaling, can not change the search volume on main carrier, perhaps do not change the search volume of the control channel form that can transmit on main carrier.
In addition, the blind Detecting number of times of each carrier wave also can carry in carrying the PDCCH signaling of carrier activation relevant information.
(4) carry PDCCH monitoring set in carrying the PDCCH signaling of carrier activation relevant information, also can carry the corresponding relation between PDCCH monitoring collection and the set of user's downlink member carrier, namely each downlink data carriers in the set of user's downlink member carrier and upstream data carrier wave (if any) the corresponding PDCCH paired with it can be carried on which or which carrier wave of PDCCH detection set.
The carrier number of considering the maximum polymerization of UE is 5, needs at least 5 bits to carry PDCCH monitoring set.Consider the reliability of PDCCH signaling, main carrier can not change, and so just needs 4 bits to carry PDCCH monitoring set.Perhaps, the bit number that is used for carrying PDCCH monitoring set can equal the carrier number that does not rely on the set of user's downlink member carrier that system is the UE configuration.
For carrying of the corresponding relation between PDCCH monitoring collection and the set of user's downlink member carrier, in a kind of situation, be N*M for the number of bits of carrying the corresponding relation between the set of user's downlink member carrier and PDCCH monitoring set, N is the carrier number in the set of user's downlink member carrier, and M is the carrier number of PDCCH monitoring set.In another case, consider the reliability of PDCCH signaling, the corresponding relation of the control channel form that can transmit on main carrier does not change, and can be (N-1) * M for the number of bits of carrying the corresponding relation between UE downlink member subset and PDCCH monitoring set.In another situation, consider that the corresponding relation with carrier dispatching can exist always, can be (N-1) * M for the number of bits of carrying the corresponding relation between the set of user's downlink member carrier and PDCCH monitoring set.In like manner, above-mentioned three kinds of situations also can consider.The carrier number of supposing the maximum polymerization of UE is N=M=5, and the number of bits that is used for carrying the corresponding relation between the set of user's downlink member carrier and PDCCH monitoring set in above-mentioned three kinds of situations is respectively 5*5=25, (5-1) * 5=20 and (5-1) * 5=20.
Distinguishingly, if man-to-man corresponding relation is adopted in the set of user's downlink member carrier and PDCCH monitoring set, need N*|log 2M| bit, || for rounding up.Consider that the corresponding relation with carrier dispatching exists always, the bit number that needs can further reduce, and is specially (N-M) * | log 2M| bit, || for rounding up, also can be taken as max[(N-M) * | log 2M|] individual bit, wherein the PDCCH monitoring set that can get of M and the N system of being respectively and the carrier number in the set of user's downlink member carrier, the system that perhaps is taken as is the carrier number that does not rely on the set of user's downlink member carrier that UE configures.
Be illustrated in figure 3 as the corresponding relation schematic diagram between user's downlink member carrier set of relating in the embodiment of the present invention and PDCCH monitoring set, suppose N=4, M=2, can be 4*2=8 for the bit number that carries the corresponding relation between the set of user's downlink member carrier and PDCCH monitoring set, the bit number that changes PDCCH monitoring set is 4, a remaining 16-8-4=4 bit can be made as definite value, for example can be set to 0, as virtual CRC check.In Fig. 3, before corresponding relation changed, the data that carrier wave C3 is corresponding and control information were all transmitted on carrier wave C3, and the data on carrier wave C4 are transmitted on carrier wave C4, and the control information on carrier wave C4 is transmitted on carrier wave C3.After corresponding relation changes, carrier wave C3 is no longer the member that the PDCCH monitoring is concentrated, carrier wave C4 has become the member that the PDCCH monitoring is concentrated, so the data that carrier wave C4 is corresponding and control information are transmitted on carrier wave C4, data on carrier wave C3 are transmitted on carrier wave C3, and the control information on carrier wave C3 is transmitted on carrier wave C4.
(5) carry carrier dispatching information in carrying the PDCCH signaling of carrier activation relevant information
Can carry simultaneously the schedule information of the carrier wave that this PDCCH dispatches in carrying the PDCCH signaling of carrier activation relevant information, or across carrier dispatching information.Especially; expansion carrier wave (the carrier wave that the expansion carrier wave may be comprised of the boundary belt between a plurality of member carriers; and can not be separately for the UE access; use to depend on other accessible carrier waves only) activation on the accessible carrier wave that depended on or the deexcitation signaling information that can carry this expansion carrier wave of scheduling, the PDCCH signaling that carries the carrier activation relevant information on rf chain on certain carrier wave can carry the schedule information of other carrier waves on this rf chain.
Concrete data dispatch can be divided into 3 classes:
(1) if by these two the incompatible expression carrier activation of acquiescence redundancy group relevant information of bit, acquiescence redundant state or scrambler and the state of acquiescence redundancy, the PDCCH signaling can be carried the data dispatch information of current certain carrier wave, activates deexcitation signaling place carrier wave as scheduling.As adopt the acquiescence redundant state in the carrier wave indication bit to represent the carrier activation relevant information, can carry be used to the schedule information of dispatching certain current carrier wave except other field of carrier wave indication bit; In addition, if adopt the state of the acquiescence redundancy in resource allocation field to represent carrier activation deexcitation information, the PDCCH signaling can be carried the carrier dispatching information of simplification.Wherein, the resource allocation field in the PDCCH signaling of resource allocation field and last scheduling is identical.
For example, if adopt the resource allocation field in DCI form 0 and DCI form 1A to represent the carrier activation relevant information, and divide bit to represent carrier activation or the deexcitation information content with the Head Section in DCI form 0 and DCI form 1A, the PDCCH signaling can be done the descending scheduling of simplification, this descending scheduling is asynchronous HARQ, the such fixed timing relationship of uplink synchronous HARQ needn't be arranged, and necessarily have the control channel scheduling.If DCI form 1A is as the PDCCH signaling that is used for activating carrier wave and while dispatching downlink data, stipulate that resource allocation field is identical with resource allocation field in last PDCCH signaling, the explanation of other fields is constant, NDI indicates re-transmission, differing in size in last time transmission block size of MCS+ resource allocation field, such PDCCH signaling are simple signalings of carrying out carrier activation or deexcitation of being used for.If DCI form 0 is also dispatched the PDCCH signaling of small-sized data simultaneously as the deexcitation carrier wave, stipulate that the resource allocation field in the control channel of resource allocation field and last scheduling is identical, other fields change descending correspondence into and explain, namely centralized/distributed resource allocation sign=frequency hopping identifies, the skew of HARQ process=demodulation pilot frequency, the filling bit of RV=(indication of non-periodic channel quality)+may exist; NDI indicates re-transmission, and the MCS+ resource allocation field is not equal to last transmission block size, and such PDCCH signaling both can be carried out carrier activation or deexcitation, can dispatch again.If carrier activation or deexcitation signaling are only to dispatch as retransmission packet, the NDI of 1 bit just can be used for the indication of up-downgoing retransfer scheduling.
(2) if when adopting signaling length to carry the PDCCH signaling of carrier activation relevant information greater than the DCI signaling conduct of total form DCI0 or DCI1A, for example, adopt DCI form 2 or DCI form 2A (wherein swap_flag or certain NDI are as carrier activation or deexcitation sign), can comprise the field for each field of expression DCI form 0 or DCI form 1 in this PDCCH signaling, that is to say this PDCCH signaling can " rollback " dispatching office at carrier wave.So-called " rollback " scheduling, in two kinds of available DCI forms that comprise under certain current transmission mode exactly, the data dispatch that adopts form 0 or form 1A to carry out.For example, current transmission mode is closed-loop MIMO, and the form that comprises is DCI 2 and DCI 0/1A, and this moment, the base station was carried out " rollback " scheduling with DCI form 0 or form 1A to UE due to the impact of channel status.In two kinds of available DCI forms that comprise under certain current transmission mode, a kind of DCI form is relevant to transmission mode, and another kind of DCI form is DCI form 0 and form 1A total between various transmission modes.
Suppose to adopt exchange identification to represent carrier activation or deexcitation sign, can reinterpret " rollback " scheduling that a DCI form 0 or DCI form 1A do signaling place carrier wave from DCI form 1, DCI form 2 or the DCI form 2A of this class signaling length greater than DCI form 0 or DCI form 1A.be illustrated in figure 4 as the DCI form 1 of each field that carries the carrier activation relevant information in the embodiment of the present invention and be used for expression DCI form 0 or DCI form 1 or the structural representation of DCI form 2 or DCI form 2A, in figure, in DCI form 1 or DCI form 2 or DCI form 2A, except obtaining the activation relevant information, carrier activation (can comprise the first sign, the second sign and the 3rd sign, except perhaps deexcitation content in carrier activation, , also comprise the field for each field of expression DCI form 0 or DCI form 1, be equivalent to comprise DCI form 1A or DCI form 0 at DCI form 1 or DCI form 2 or DCI form 2A.
(3) across carrier dispatching the time, needing to add carrier wave indication bit position (CarrierIndicator Field is called for short CIF) in the PDCCH signaling, to notify this PDCCH be the transfer of data of specifically dispatching which carrier wave.Such as comprising two carrier wave C1 and C2 in the set of user's downlink member carrier, general, can come across the transfer of data on carrier dispatching C2 by the indication of CIF in the PDCCH signaling that sends on C1.At this moment, if for UE, C1 is activated state, and C2 is deactivated state, can activate C2 by the CIF that is used to refer to C2 in the PDCCH that sends this moment on C1, and dispatch simultaneously the transfer of data on C1.General, can activate by the PDCCH across carrier dispatching that CIF realizes the carrier wave of certain deactivated state, and the while can be dispatched the transfer of data of this PDCCH signaling place carrier wave.Do like this and can save signaling consumption.
(6) carry the channel quality information resource allocation information of (Channel Quality Information is called for short CQI) in carrying the PDCCH signaling of carrier activation relevant information
Carry out the CQI that the descending scheduling of UE depends on the UE uplink feedback base station.In the LTE system, the CQI of UE feedback is divided into periodically CQI and aperiodicity CQI.Periodically the resource of CQI is that the proprietary signal deployment of RRC is passed through in the base station, capable physically control channel (the Physical UplinkControl Channel of general transmission, be called for short PUCCH) in, when existing upstream data to send simultaneously, with in the capable physically shared channel of upstream data multiplexing transmission together (Physical Uplink Control Channel is called for short PUSCH); For aperiodicity CQI, the base station can not remain for transmitting for UE the resource of aperiodicity CQI in advance, but comes Resources allocation by dynamic PDCCH scheduling (uplink scheduling), transmits in PUSCH.When existing simultaneously upstream data to send, aperiodic CQI with upstream data multiplexing transmission together on the resource of dynamic assignment, the CQI aperiodic modulation system identical with the upstream data employing, aperiodic, the code check of CQI was adjusted according to the code check of data; When not existing upstream data to send, only send CQI aperiodic on the resource of distributing, to be QPSK, according to the RB number of Resources allocation determine only by code check for modulation system.
Because CQI is divided into periodically and two kinds of aperiodicity, the below is divided into two kinds of situations and introduces.
(1) periodically CQI has adopted in the LTE-A system of carrier aggregation technology, for periodicity CQI, the base station is independent of the resource that is used for sending CQI (resource that is used for transmission CQI is the resource allocation information of CQI namely) of carrier wave and UE usually with the proprietary signal deployment of RRC for each descending carrier in the set of user's downlink member carrier on a up-link carrier.This mode need to be UE configuration CQI resource allocation information with proprietary RRC signaling, in fact, can carry the resource allocation information that carries CQI in the PDCCH signaling of carrier activation relevant information fully in various embodiments of the present invention, the PDCCH signaling of carrying the CQI resource allocation information can be the PDCCH signaling of the descending carrier activation information that carries.
The CQI resource of each UE can be distributed to according to the statistic multiplexing rule judgment in the base station, and the resource allocation information of CQI is carried in the PDCCH signaling.
So-called statistic multiplexing refers to the base station in advance for a plurality of UE have distributed an identical channel resource set that is used for sending CQI, and the resource in this set can be less than the sum of the resource requirement of this a plurality of UE; A plurality of UE are coordinated to the use of this resource collection by certain rule in the base station, specifically notify the resource of each its current use of UE by dynamic signaling, have improved the utilization ratio of resource.
So-called statistic multiplexing rule refers to, a plurality of UE can share some CQI resource (this CQI resource that shares can by the base station by the proprietary signal deployment of RRC to UE), and the base station is that current UE need to guarantee that this CQI resource do not used by other UE when distributing the CQI resource.This rule can be determined according to the demand of LTE-A system.
The carrier wave of deexcitation is need to not feed back CQI for it, and when having activated certain carrier wave, notice UE should activate CQI resource corresponding to carrier wave in current PDCCH signaling.Illustrate, the base station can be distributed to UE1 and UE2 to 4 CQI resources on a up-link carrier, during beginning, to be in the carrier wave of activated state be respectively carrier wave C1 and carrier wave C2 for UE1 and UE2, corresponding CQI resource is respectively CQI1 and CQI2, when the carrier wave C2 of UE1 was activated by the PDCCH signaling in the base station, the CQI resource of notice carrier wave C2 was CQI3 in the PDCCH signaling simultaneously; In like manner, when the carrier wave C3 of UE2 was activated by the PDCCH signaling in the base station, the CQI resource of notice C3 was CQI4 in signaling simultaneously.
In the embodiment of the present invention, carry the periodically resource allocation information of CQI in carrying the PDCCH signaling of carrier activation information, only use a PDCCH signaling namely can realize activating the function of the resource of carrier wave and configuration cycle property CQI, saved expense.And the CQI resource of base station assigns can guarantee when taking full advantage of CQI that according to the statistic multiplexing regular allocation each UE can both be assigned to the CQI resource, has improved the utilance of CQI resource.
(2) aperiodicity CQI
In prior art, aperiodic, the scheduling of CQI was to realize by the DCI form 0 that is used for uplink scheduling, bit in DCI form 0 in concrete FDD system comprises: the Head Section of 1 bit divides bit, the frequency modulation sign of 1 bit, and resource allocation field comprises N bit, N is determined by system bandwidth, modulation coding mode 5 bits, new data packets indication 1 bit, power control value 2 bits, demodulation pilot frequency cyclic shift 3 bits, aperiodic, CQI triggered 1 bit.
In embodiments of the present invention, can aperiodic CQI resource allocation information be placed in the PDCCH signaling that carries carrier activation information, can pare down expenses like this, because only need this moment the shared resource of notice CQI aperiodic to get final product, other field in prior art in DCI form 0 can save.
(7) carry the trigger message that sends the resource allocation information of detection reference signal (Sounding Reference Signal, SRS) and be used for triggering UE transmission SRS for triggering UE in carrying the PDCCH signaling of carrier activation relevant information
Carry out the SRS that the uplink scheduling of UE depends on the up transmission of UE the base station.In prior art, the resource allocation information of SRS is on last symbol of each subframe, and a plurality of UE can pass through the time-division, and frequency division and code are assigned to multiplexing, transmit according to the parameter of RRC configuration signal.
Adopted in the LTE-A system of carrier aggregation technology, be used for the resource-constrained of transmitting SRS, need to consider to increase the resource that is used for transmitting SRS, a scheme is to come transmitting SRS by the cyclic shift of demodulation pilot frequency, just need to trigger the transmission of SRS on cyclic shift this moment, can carry the resource allocation information (resource allocation information is the cyclic shift of the concrete demodulation pilot frequency that distributes) of SRS transmission and be used for triggering the trigger message that UE sends SRS in carrying the PDCCH signaling of carrier activation relevant information.
In the embodiment of the present invention, carry in carrying the PDCCH signaling of up-link carrier active information for triggering UE and send the trigger message of SRS and the resource allocation information of SRS, can dynamically trigger UE and send SRS, the resource allocation information of SRS is dynamically notified to UE, and owing to not needing to transmit this trigger message and resource allocation information with other signaling separately, but with signaling of carrier activation information commons, saved expense.
In addition, the base station can be according to up carrier set of the upstream traffic of UE configuration, i.e. dispatching uplink data in this set, and corresponding UE need to send SRS on the carrier wave in this is gathered.Accordingly, the base station can in up carrier set, send SRS for UE and activate dynamically or deactivating operation.For example, the base station has configured 3 up-link carriers (comprising C1C2 and C3) according to the average traffic in certain period of UE to UE and corresponding SRS resource sends SRS for UE, when the UE traffic carrying capacity hour, the base station can send the SRS operation by deexcitation UE on certain several carrier wave, such as the base station only allows UE send SRS on C1; When the UE traffic carrying capacity was larger, the operation that other two carrier waves of UE send SRS can be opened in the base station, and namely UE will send SRS on 3 carrier waves.In the present embodiment, the base station can be controlled dynamically UE and send SRS, has optimized the utilization of resources, has saved signaling consumption.
