Before the technical scheme provided the embodiment of the present invention is described in detail, first the technical term that the present invention relates to or technical characteristic are made an explanation:
Special subframe structure: the special subframe structure of the embodiment of the present invention, the special subframe structure that both can specify in the existing protocol shown in table 1 also can be the special subframe structure that base station configures voluntarily.
The configuration information of special subframe structure: the design parameter that both can be special subframe structure, such as DwPTS, GP, UpPTS length information separately, also can be special subframe structure numbering in Table 1, can also be that other can determine the information of special subframe structure.
Base station: the base station in the embodiment of the present invention is the base station in TDD system.Such as, the evolved base station (eNB) in TDD-LTE system, dominant base (MeNB), Home eNodeB (HeNB) etc.
Special subframe structural allocation, in radio frames or field, refers to, both can use this special subframe structure in whole radio frames, also can use different special subframe structures respectively at two of a radio frames field.In enforcement, base station according to demand, can by whole special subframe structural allocation in radio frames, also can by whole special subframe structural allocation in field, can also a part of special subframe be configured in radio frames, another part special subframe is configured in field.
Below in conjunction with accompanying drawing, the technical scheme that the embodiment of the present invention provides is described in detail.
As shown in Figure 1, the embodiment of the present invention provides a kind of communication means of base station side, specifically comprises following operation:
Step 100, configuration at least two kinds of special subframe structures, in the special subframe structure of configuration, the GP length of at least one special subframe structure is not identical with the GP length of other special subframe structures, and various special subframe structural allocation is in different radio frames or field.
Step 110, send the configuration information of above-mentioned at least two kinds of special subframe structures to terminal.
So that the radio frames at the special subframe structure place of configuration or field use described special subframe structure to communicate with described terminal.
In the embodiment of the present invention, special subframe structure both can be static or semi-static configuration, also can be dynamic-configuration.
If above-mentioned at least two kinds of special subframe structures are static or semi-static configuration, in system broadcast message, the configuration information of above-mentioned at least two kinds of special subframe structures can be sent to terminal.Wherein, the radio frames at special subframe structure place or the information of field is also carried in this system broadcast message.
The implementation of carrying the information of radio frames or field in system broadcast message has multiple, exemplifies two kinds below:
The information carrying mode one of radio frames or field:
In system broadcast message, carry the radio frames at often kind of special subframe structure place or the information of field.
The information carrying mode two of radio frames or field:
Suppose to be configured with L kind special subframe structure, wherein L be not less than 2 positive integer.Then in system broadcast message, carry the wherein radio frames at L-1 kind special subframe structure place or the information of field.
The no matter carrying mode of the information of which kind of radio frames or field, the particular content of the information of radio frames or field also has multiple.
Such as, the radio frames at special subframe structure place or the numbering of field can be determined by following formula:
FN mod N=M
Wherein, FN is the numbering of radio frames or field, and N is the repetition period of special subframe structure place radio frames or field, and M is 0 or positive integer, and the value of M is fixed.So, the radio frames at special subframe structure place of carrying in system broadcast message or the information of field can be N corresponding to special subframe structure, also can be N and M corresponding to special subframe structure.If radio frames or half frame information at the special subframe structure place of carrying in system broadcast message are only N, then M is about definite value.

To be configured with 4 kinds of special subframe structures, suppose wherein a kind of special subframe be configured in be spaced apart N-1 radio frames or field on, the relative position of other two kinds of special subframe structure place radio frames or field and this special subframe structure place radio frames or field is fixed.Also has a kind of special subframe structural allocation in all the other radio frames or subframe.In this case, can be carried first three in system broadcast message and plant the radio frames at special subframe structure place or the information of field.Because the relative position of these three kinds of special subframe structure place radio frames or field is fixed, namely these three kinds of special subframes are all configured in and are spaced apart as in the radio frames of N-1 or field, so, the information of one of them special subframe place radio frames or field is N, or the M that N is corresponding with this special subframe, the information of two other special subframe place radio frames or field is the relative position of this special subframe place radio frames or field relatively.Or the information of these three special subframe place radio frames or field is N, or N and M corresponding to corresponding special subframe.
If above-mentioned at least two kinds of special subframe structures are dynamic-configuration, can before transmission special subframe, send signaling to terminal, in this signaling, carry the configuration information of the special subframe structure that current wireless frame, reference field, one group of radio frames or one group of field use.The configuration information of above-mentioned at least two kinds of special subframe structures is sent in this way to terminal.Wherein, this signaling can be physical layer control signal (such as PDCCH, EPDCCH etc.), medium education (MAC) signaling or radio resource control (RRC) signaling etc.
If this signaling is physical layer control signal, specifically in first subframe of radio frames or field, this physical down control signal can be sent to terminal.
Such as, for the special subframe structure be configured in radio frames, before sending the special subframe in these radio frames, signaling is sent to terminal, the special subframe structure that the current wireless frame carrying its place in this signaling uses, or the configuration information carrying the special subframe structure that one group of radio frames uses.This group radio frames can be comprise the current wireless frame at this signaling place and follow-up continuous or discrete multiple radio frames, continuous or discrete multiple radio frames after also can being this signaling place present sub-frame.In addition, this group radio frames can be the radio frames that used special subframe structure is identical, also can be the radio frames that used special subframe structure is different.
For the special subframe structure be configured on field, information entrained in its signaling describes and with reference to foregoing description, can repeat no more here.
Figure 2 shows that the communication means of a kind of end side that the embodiment of the present invention provides, specifically comprise following operation:
The configuration information of at least two kinds of special subframe structures that step 200, reception base station send, in the special subframe structure of configuration, the GP length of at least one special subframe structure is not identical with the GP length of other special subframe structures, and various special subframe structural allocation is in different radio frames or field.
Step 210, the special subframe structure used according to the configuration information determination different radio frame received or field.
So that the radio frames at the special subframe structure place of configuration or field use described special subframe structure to communicate with above-mentioned base station.
The method that the embodiment of the present invention provides, after base station is configured with different special subframe structures for different radio frames or field, terminal can be known as the special subframe structure of different radio frame or field configuration, to communicate with base station.
In the embodiment of the present invention, the mode of base station side configuration special subframe structure is different, and the mode that terminal receives the configuration information of special subframe structure is also different.
If base station side is static or semi-static configuration special subframe structure, so, terminal receives the configuration information of above-mentioned at least two kinds of special subframe structures that base station sends, specifically: terminal receives the system broadcast message that base station sends, and carries the configuration information of above-mentioned at least two kinds of special subframe structures in this system broadcast message.Wherein, the radio frames at special subframe structure place or the information of field is also carried in this system broadcast message.
The implementation of carrying the information of radio frames or field in system broadcast message can with reference to the description of above-mentioned base station side method.
The no matter carrying mode of the information of which kind of radio frames or field, the particular content of the information of radio frames or field also has multiple.Specifically can with reference to the description of base station side embodiment of the method.
Such as, the radio frames at special subframe structure place or the numbering of field can be determined by following formula:
FN mod N=M
Wherein, FN is the numbering of radio frames or field, and N is the repetition period of special subframe structure place radio frames or field, and M is 0 or positive integer, and M value is fixed.So, the radio frames at special subframe structure place of carrying in said system broadcast or the information of field are N corresponding to special subframe structure, or are N and M corresponding to special subframe structure.
Based on this, the implementation of the special subframe structure used according to the configuration information determination different radio frame received or field can be: N and M corresponding according to special subframe structure determines the radio frames at this special subframe structure place or the numbering of field; The special subframe structure of its place radio frames or field is determined according to the configuration information of this special subframe structure.Wherein, if the radio frames at the special subframe structure place of carrying in system broadcast message or half frame information are only N, then M is about definite value.
Concrete, if carry the information of often kind of special subframe structure place radio frames or field in system broadcast message, so determine according to above-mentioned processing procedure the special subframe structure that often kind of special subframe structure place radio frames or field use respectively.If carry the radio frames at part special subframe structure place or the information of field in system broadcast message, then can determine according to above-mentioned processing procedure the special subframe structure that these radio frames or field use, then determine the special subframe structure that remaining radio frames or field use.Such as, if carry configuration information and wherein a kind of radio frames at special subframe structure place or the information of field of two kinds of special subframe structures in system broadcast message, then the special subframe structure that these radio frames or field use first is determined.Then, according to the configuration information of another the special subframe structure received, determine the special subframe structure that remaining radio frames or field use.Again such as, if carry configuration information and the wherein radio frames at 3 kinds of special subframe structure places or the information of field of 4 kinds of special subframe structures in system broadcast message, and in the radio frames at these 3 kinds of special subframe structure places or the information of field, only have a kind of radio frames at special subframe structure place or the information of field to be N and M that this special subframe is corresponding, the other radio frames at two kinds of special subframe structure places or the information of field are the relative position of this special subframe structure place radio frames or field relatively.So, first determine this special subframe structure, then determine other two kinds of special subframe structures according to relative position information, finally determine the 4th kind of special subframe structure.
If base station side dynamic-configuration special subframe structure, so, receive the configuration information of at least two kinds of special subframe structures that base station sends, can be specifically: before reception special subframe, receive the signaling that base station sends, in this signaling, carry the configuration information of the special subframe structure that current wireless frame, reference field, one group of radio frames or one group of field use.Wherein, this signaling can be physical layer control signal, medium education signaling or radio resource control signaling etc.
If this signaling is physical layer control signal, concrete, first subframe of radio frames or field receives this physical down control signal that base station sends.In this way, the configuration information of the various special subframe structures that base station sends is received.Describing for information entrained in signaling can with reference to above-mentioned base station side embodiment of the method.
Below in conjunction with embody rule scene, the method that the embodiment of the present invention provides is described in detail.
Between existing a kind of LTE-TDD system small area, clock synchronization scheme is Network Based the air interface synchronization scheme monitored.
At LTE version 9(LTE Rel-9) in research to time division duplex Home eNodeB (TDD Home eNB), a kind of air interface synchronization technical scheme (3GPP TR36.922) being applicable to TDD base station is proposed.Its main thought is: the main synchronisation source community (community under the MeNB in Fig. 3) of air interface synchronization configures the shorter special subframe of a kind of GP (as shown in Figure 3, MeNB is configured to special subframe configuration 4).The to be synchronized Target cell (community HeNB1 Fig. 3 under) synchronous from the direct acquisition time in main synchronisation source community configures the relatively large special subframe of a kind of GP (as shown in Figure 3, HeNB1 is configured to special subframe configuration 1), like this, Target cell to be synchronized can in the GP of its special subframe relative synchronization cell-of-origin before vacating more several OFDM symbol go the reference signals such as the CRS detecting main synchronisation source community synchronous with acquisition time.Similarly, special subframe that can not be relatively larger from object synchronization community (community under the HeNB2 Fig. 3) GP configuring to be synchronized that the direct acquisition time in main synchronisation source community is synchronous (as shown in Figure 3, the special subframe configuration 0 of HeNB2 configuration), like this, Target cell to be synchronized can in the GP of its special subframe relative to synchronized cells before vacating more several OFDM symbol to go to detect the reference signals such as CRS synchronous to obtain.
Visible, in air interface synchronization scheme, require that base station to be synchronized configures longer GP and goes the downstream signal accepting the transmission of synchronisation source base station synchronous to obtain.Due to special subframe structure in existing LTE-TDD frame structure once configuration, all radio frames all adopt identical GP length, and in fact base station air interface synchronization does not need base station to be synchronized in each radio frames, monitor the downstream signal of synchronisation source base station.Therefore, based on existing system, the air interface synchronization scheme based on TDD special subframe be implemented, then require that longer GP time slot is distributed in base station to be synchronized in all radio frames, because GP time slot can not transmitting physical signal, therefore significantly increase the expense of system, reduce system effectiveness.
For the HeNB1 in Fig. 3, the method that provides of the application embodiment of the present invention, HeNB1 is respectively the radio frames that needs to carry out eating dishes without rice or wine between base station to monitor and does not need the radio frames configuration special subframe structure carrying out eating dishes without rice or wine between base station to monitor.Wherein, the GP length of the special subframe structure needing the radio frames of carrying out eating dishes without rice or wine to monitor between base station to use is greater than the GP length of the special subframe structure not needing the radio frames of carrying out eating dishes without rice or wine to monitor between base station to use.
Preferably, for needing to carry out the radio frames eating dishes without rice or wine between base station to monitor and not needing the radio frames of carrying out eating dishes without rice or wine between base station to monitor to configure a special subframe structure respectively.So, the special subframe structure needing the radio frames of carrying out eating dishes without rice or wine to monitor between base station to use is called special subframe structure one, and the special subframe structure not needing the radio frames of carrying out eating dishes without rice or wine to monitor between base station to use is called special subframe structure two.
Certainly, also can according to communication requirement, be respectively the radio frames that needs to carry out eating dishes without rice or wine between base station to monitor and do not need the radio frames of carrying out eating dishes without rice or wine between base station to monitor to configure multiple special subframe structure respectively.
Because base station is when carrying out eating dishes without rice or wine between base station to monitor, need the GP that configuration is relatively long, so that the enterprising line space mouth of the OFDM symbol had more in GP is monitored.Eat dishes without rice or wine between base station to monitor is carry out in the cycle, so, by for needing to carry out the radio frames eating dishes without rice or wine between base station to monitor or field and not needing the radio frames carrying out eating dishes without rice or wine between base station to monitor or field to configure different special subframe structures, when making base station need to carry out eating dishes without rice or wine to monitor, using longer GP, when not carrying out eating dishes without rice or wine to monitor, using shorter GP with signal transmission, thus improve system effectiveness, reduce overhead.
If the special subframe structure one that static or semi-static configuration needs the radio frames of carrying out eating dishes without rice or wine to monitor between base station to use and the special subframe structure two not needing the radio frames of carrying out eating dishes without rice or wine to monitor between base station to use, and every N number of radio frames carries out eating dishes without rice or wine between a base station to monitor.So, the System Frame Number (SFN) carrying out eating dishes without rice or wine between base station the radio frames monitored is needed can be determined by formula F SN mod N=M.
HeNB1 sends the configuration information of special subframe structure one, the configuration information of special subframe structure two and the value of N in system broadcast message.Optionally, the value of M is also carried in system broadcast message.If do not carry the value of M in system broadcast message, then the value of the M that makes an appointment with terminal.
Concrete, new field can be defined in system broadcast message (such as system information block SIB1), for carrying above-mentioned full detail.So, the field of carrying special subframe structural allocation defined in original agreement no longer can carry the configuration information of special subframe structure.The field of carrying special subframe structural allocation defined in original agreement can also continue the configuration information carrying special subframe structure, and special subframe structure corresponding for this field is called special subframe structure three.In this case, in the mobility measurements process of terminal, use special subframe structure three to communicate with terminal.When needs carry out eating dishes without rice or wine between base station monitoring, use special subframe structure one, all the other are wireless town uses special subframe structure two.
Can also definition is new in the system broadcast message (such as SIB1) field, for the value of the configuration information and N that carry special subframe structure one.If send the value of M, also carry in the field.The field of carrying special subframe structural allocation defined in original agreement carries the configuration information of special subframe structure two.In this case, when needs carry out eating dishes without rice or wine between base station monitoring, use special subframe structure one, all the other are wireless town uses special subframe structure two.
Terminal receives the system broadcast message that HeNB1 sends, and therefrom obtains configuration information and other information of special subframe structure.
Concrete, if carry the configuration information of special subframe structure one, the configuration information of special subframe structure two and the value of N in the field of above-mentioned new definition, optionally, also carry the value of M.Terminal obtains these information from the field of new definition, according to N and M, determines the SFN of radio frames, and according to the configuration information of special subframe structure one, determines the special subframe structure one that the radio frames that these SFN are corresponding uses.If the field of carrying special subframe structural allocation defined in original agreement also carries the configuration information of special subframe structure three, then determine the special subframe structure three that radio frames corresponding to mobility measurements process uses, determine the special subframe structure two that all the other radio frames use; If the field of the carrying special subframe structural allocation no longer carry information defined in original agreement, then determine the special subframe structure two that the radio frames outside the radio frames that above-mentioned SFN is corresponding uses.
If the special subframe structure that dynamic-configuration radio frames uses, and every N number of radio frames carries out eating dishes without rice or wine between a base station to monitor.So, the System Frame Number (SFN) carrying out eating dishes without rice or wine between base station the radio frames monitored is needed can be determined by formula F SN mod N=M.
HeNB1, before sending the special subframe in radio frames, sends signaling to terminal, the special subframe structure that the current wireless frame carrying its place in this signaling uses, or the configuration information carrying the special subframe structure that one group of radio frames uses.This group radio frames can be comprise the current wireless frame at this signaling place and follow-up continuous or discrete multiple radio frames, continuous or discrete multiple radio frames after also can being this signaling place present sub-frame.In addition, this group radio frames can be the radio frames that used special subframe structure is identical, also can be the radio frames that used special subframe structure is different.
For physical layer control signal, HeNB1 carried out eating dishes without rice or wine between base station, in first subframe of the radio frames monitored, to send physical layer control signal, carry the configuration information of special subframe structure one in this physical layer control signal to terminal in each needs.Or carry the special subframe configuration configuration information of one and the value of N in the physical layer control signal sent in first subframe of the first radio frames monitored that needs to carry out to eat dishes without rice or wine between base station, optionally, also carry the value of M.Further, if the field of the carrying special subframe structural allocation no longer carry information defined in original agreement, then HeNB1 is not needing to carry out eating dishes without rice or wine in first subframe of the radio frames monitored between base station, send physical layer control signal to terminal, in this physical layer control signal, carry the configuration information of the special subframe that this radio frames or one group of radio frames use; Certainly, if do not need the special subframe structure of these radio frames of dynamic-configuration, the configuration information of special subframe structure two can also be sent by system broadcast message.Visible, dynamic special subframe configuration and special subframe configuration in advance can be combined.If the field of carrying special subframe structural allocation defined in original agreement still carries the configuration information of special subframe structure, then HeNB1 can carry the configuration information of special subframe structure two in this field.
Before reception special subframe, terminal receives the above-mentioned signaling that HeNB1 sends, and therefrom obtains the configuration information of special subframe structure.
Concrete, if carry the configuration information of special subframe structure one or the configuration information of special subframe structure two in this signaling, terminal determines the special subframe structure that this radio frames uses.If the field of carrying special subframe structural allocation defined in original agreement also carries the configuration information of special subframe structure, then the special subframe structure that radio frames corresponding to the configuration information determination mobility measurements process of the special subframe structure of carrying according to this field uses.
