Description

A kind of method of E-HICH channel quality detection, system and equipment
Technical field
The present invention relates to wireless communication technology field, particularly relate to a kind of method, system and equipment of E-HICH channel quality detection.
Background technology
1.28Mcps the TDD system has introduced HSUPA (High Speed Uplink PacketAccess in R7, the High Speed Uplink Packet access) technology, this technology has realized the fast packet scheduling based on Node B (base station), and by mixed automatic retransfer, and AMC (adaptive modulationcoding, Adaptive Modulation and Coding) etc. key technology has improved the bearing capacity of system up-link data service greatly.
The HSUPA technology is divided into scheduled transmission and non-scheduled transmission, and wherein the flow process of scheduled transmission is as shown in Figure 1:
Step 101, UE (User Equipment, user terminal) there is uplink strengthening data etc. to be sent in the buffer memory, UE is in the request of the upper transmission of E-RUCCH (E-DCH Random access UplinkControl Channel, E-DCH accesses ascending control channel at random) scheduling of resource;
Step 102, Node B carry out scheduling of resource according to the dispatch request information of receiving, and in the upper resource license information that sends of E-AGCH (E-DCH Absolute Grant Channel, E-DCH absolute grant channel);
Step 103, UE is according to the resource scheduling information of receiving, carry out E-TFC (E-DCH TransportFormat Combination, the E-DCH transformat combination) selects, select suitable TBS (TransportBlock Size, transmission block is big or small) and modulation system, encode afterwards, modulation, at E-PUCH (E-DCHPhysical Uplink Channel, the E-DCH physical uplink channel) the upper uplink strengthening data that sends, TPC (Transmit Power Control, transmitting power control) has carried the power control commands word for the E-AGCH channel in the territory;
Step 104, Node B receive after the E-PUCH, the processing of decoding obtains ACK/NACK information according to CRC check, is mapped to E-HICH (E-DCH HARQ acknowledge Indicator Channel after the coding, E-DCH HARQ, answering indication signal channel) feeds back to this UE on;
By above-mentioned steps, the data that UE has just finished a scheduled transmission process send.
And the non-scheduled transmission among the HSUPA is different from scheduled transmission, does not need to wait for that Node B distributes physical resource by E-AGCH, and the E-PUCH resource is in advance by network side configuration and notice UE.UE directly sends upstream data in the E-PUCH resource of configuration, and according to timing relationship, receives the feedback of network side at E-HICH.At this moment, owing to there not being E-AGCH, the TPC territory on the E-PUCH is meaningless.
In HSPA+, introduced up semi-continuous scheduling transmission, namely Node B is the E-PUCH resource of UE assignment period at E-AGCH.Node B can be at any time changes or regains semi-continuous resource at E-AGCH.Before this, UE sends data in the semi-continuous E-PUCH resource that Node B distributes, and according to timing relationship, receives the feedback of network side at E-HICH.For the E-PUCH that does not have E-AGCH, the TPC territory on it is also meaningless.
In realizing process of the present invention, the inventor finds prior art, and there are the following problems at least:
When in the situation that only there is the E-HICH channel in down direction, because the E-HICH channel does not have CRC (Cyclic Redundancy Check, redundant cyclic check code), and signal that one can multiplexing a plurality of UE on the E-HICH, UE can't obtain the quality of this subscriber signal on the E-HICH channel, therefore can't carry out descending synchronous/asynchronous detection.

Embodiment
Main thought of the present invention comprises: Node B uses default replacement sequence to replace in original series, compare according to the replacement sequence that receives and the replacement sequence of presetting by UE, and then detect the E-HICH channel quality, solved that the E-HICH channel does not have CRC and for detecting the problem of E-HICH channel quality in the situation of multiuser multiplexing.
Below in conjunction with the accompanying drawing among the present invention, the technical scheme among the present invention is carried out clear, complete description, obviously, described embodiment is a part of embodiment of the present invention, rather than whole embodiment.Based on the embodiment among the present invention, the every other embodiment that those of ordinary skills obtain under the prerequisite of not making creative work belongs to the scope of protection of the invention.
The embodiment of the invention provides a kind of detection method of E-HICH channel quality, be applied in HSPA system or the HSPA+ system, the base station is by adopting the unspecified idle bit position of default replacement sequence replacing original series, user terminal is by replacing Sequence Detection E-HICH channel quality, finish the down-going synchronous detection of loss of mains, concrete steps as shown in Figure 2:
Step 201, Node B use default replacement sequence to replace in the original series of E-HICH channel, obtain replacing rear sequence.
Default replacement sequence refers to, replaces known bit sequence in original series.The replacement sequence that should preset is one 8 bit sequence z u(u=0...7), its value can be complete 1 or the sequence that replaces of full 0 or 1,0 etc.
Should default replacement sequence can be cell-level also can be user class.If default replacement sequence is cell-level, then Node B is known this replacement sequence by predefine mode or high-level signaling mode.Wherein, the predefine mode refers to pre-defined replacement sequence in agreement, and Node B can be known this replacement sequence according to agreement.This replaces sequence in case determine, can not change.Particularly, for example define one 8 bit sequence in agreement, Node B stipulates according to agreement, replaces 8 bit sequences of this definition in the idle bit position of original series; Perhaps several 8 mutually orthogonal bit sequence and service regeulations of definition in agreement such as 88 mutually orthogonal bit sequences of definition, and are stipulated the corresponding relation of each bit sequence and E-PUCH physical resource.Node B determines default replacement sequence according to the E-PUCH physical resource that UE takies, and replaces in the idle bit position of original series.When upper multiplexing a plurality of users' the feedback information of an E-HICH, determine according to each user's E-PUCH physical resource at the replacement sequence nucleotide sequence of the replacement of the clear position of original series, and 8 the bit sequence of replacing is mutually orthogonal.The high-level signaling mode refers to replace sequence to be determined by RNC, and passes through the NBAP signaling of Iub mouth, particularly, is the replacement sequence notice Node B that will preset by the Physical Shared Channel reconfigure command.UE is known the replacement sequence that this is default by system broadcasts or RRC signaling.If default replacement sequence is the UE level, be the sequence of 8 bits of each user assignment, the bit sequence between different user can be the same or different, and replacement sequence that then should be default is determined by Node B or is determined by RNC.Particularly, Node B determines that mode refers to when link establishment, is defined certain user's the replacement sequence that should preset by Node B, and by the NBAP signaling RNC of Node B by the Iub mouth, pass through RRC signaling UE by RNC, thereby make UE and Node B should replace the sequence cognitive consonance.RNC determines that mode refers to that RNC determines certain user's default replacement sequence when link establishment, and the default replacement sequence of using by this UE of NBAP signaling Node B, by RRC signaling UE, thus the replacement sequence cognitive consonance that UE and Node B should be preset.
Secondly, Node B divides original series, and replaces the replacement sequence that institute defines or knows in original series, sequence after formation is replaced.
Sequence was sent to UE after step 202, Node B should replace, so that UE obtains the E-HICH channel quality according to sequence after replacing.
The embodiment of the invention provides a kind of detection method of E-HICH channel quality, be applied in HSPA system or the HSPA+ system, Node B is by adopting the unspecified idle bit position of default replacement sequence replacing original series, UE will be by replacing Sequence Detection E-HICH channel quality, finish the down-going synchronous detection of loss of mains, concrete steps as shown in Figure 3:
Sequence after the replacement that step 301, UE reception Node B obtain after using default replacement sequence to replace in the original series of E-HICH channel.
At first, sequence after the replacement that obtains after in original series, using default replacement sequence to replace of Node B.
Secondly, sequence sent to UE after Node B will replace, sequence after this replacement that UE reception Node B sends.
The replacement sequence that step 302, UE obtain receiving according to sequence after replacing.
Concrete, sequence d after the replacement of UE reception E-HICH channel h, sequence d after will replacing hAfter carrying out despreading, demodulation, the replacement sequence that obtains receiving.
The replacement sequence that step 303, UE will receive compares with the replacement sequence of presetting, and obtains the E-HICH channel quality according to comparative result.
At first, UE is known this replacement sequence, can pass through the predefine mode, from broadcast reception or high-level signaling mode.Concrete, as described in step 201.
Secondly, UE adopts the mode of comparative sequences according to the replacement sequence that receives, and detects the E-HICH channel quality.Concrete, UE has obtained default replacement sequence by step 302, and the default replacement sequence that replacement sequence and the UE of reception are known compares by bit, replaces the correctness detection E-HICH channel quality of sequence according to transmission.
The embodiment of the invention uses default replacement sequence to replace in original series by Node B, compare according to the replacement sequence that receives and the replacement sequence of presetting by UE, and then detection E-HICH channel quality, realized that UE is to the detection of E-HICH channel quality in the situation that the E-HICH channel does not have CRC and is multiuser multiplexing.
The embodiment of the invention provides a kind of detection method of E-HICH channel quality, be applied in HSPA system or the HSPA+ system, mode by the default replacement sequence of RNC definition, Node B adopts the unspecified idle bit position of default replacement sequence replacing original series, UE will be by replacing Sequence Detection E-HICH channel quality, finish the down-going synchronous detection of loss of mains, concrete steps as shown in Figure 4:
Step 401, the default replacement sequence of RNC definition.
Adopt scheduled transmission, non-scheduled transmission or semi-continuous scheduling transmission, Node B carries out the cataloged procedure of existing E-HICH channel, the burst format of E-HICH channel adopts default replacement sequence to replace the unspecified idle bit bit sequence of original series namely to refer to Sparebits in the alternate figures 3 all as shown in Figure 5.Default replacement sequence refers to, is the known bit sequence that Spare bits fills in the position among Fig. 3 in the idle bit position of original series.The default replacement sequence of RNC is one 8 bit sequence z u(u=0...7), its value can be complete 1 or the sequence that replaces of full 0 or 1,0 etc.
Step 402, RNC notify Node B and the defined default replacement sequence of UE by the high-level signaling mode.
Concrete, the replacement sequence z that RNC should preset by RRC signaling UE u, the replacement sequence z that should preset by NBAP signaling Node B uThus, UE and Node B have all been known this default replacement sequence z u, the sequence cognitive consonance is replaced to this in both sides.
Need to prove, when the mode that adopts the default replacement sequence of RNC definition, this default replacement sequence can change.When RNC changes default replacement sequence, with repeating step 402, new default replacement sequence is notified to Node B and UE.
Step 403, Node B determine the transmitting power of this replacement sequence.
Concrete, Node B determines that the transmitting power of this replacement sequence can be in following two kinds any.
(a) Node B arranges the transmitting power of replacing sequence according to the transmitting power of the orthogonal sequence of E-HICH channel, and for example the power with orthogonal sequence multiply by certain power factor γ, thereby obtains replacing the transmitting power of sequence.
(b) Node B arranges the transmitting power of replacing sequence according to the transmitting power of the Midamble of E-HICH channel, and for example Node B multiply by certain factor-beta with the transmitting power of the Midamble of E-HICH channel, thereby obtains replacing the transmitting power of sequence.
Need to prove, when a plurality of orthogonal sequence of a plurality of users of E-HICH channel bearing, Node B can adopt the mode of figuration to send default replacement sequence.Wherein, figuration refers to the position according to different user, directionally sends data to different directions, improves the quality of reception of data.And the transmitting power that Node B can also consider the multi-user orthogonal sequence arranges the transmitting power of replacing sequence.
Step 404, the existing E-HICH channel coding method of employing are encoded to data, produce original series.
Concrete, existing E-HICH chnnel coding flow process is: it is SF=16 that the E-HICH channel adopts QPSK modulation system, spreading factor, and total bit number that can carry on the physical resource is 88 bits.Protocol definition 80 orthogonal sequences that length is 80 bits, for scheduled transmission, a user's ACK/NACK represents with an orthogonal sequence; For non-scheduled transmission and semi-continuous scheduling transmission, each user's feedback is used two orthogonal sequences, and one is used for representing ACK/NACK, and another represents TPC/SS.Because the orthogonality of sequence, the E-HICH channel is multiple users share, and namely the information such as a plurality of users' ACK/NACK and TPC/SS can be at same E-HICH channel bearing.After network has been determined user's orthogonal sequence separately of an E-HICH channel, orthogonal sequence carried out XOR, randomization and scrambling after, form original series b H, 0, b H, 1..., b H, 79
Step 405, Node B use default replacement sequence to replace in the idle bit position of the original series of E-HICH channel.
Concrete, Node B divides the original series of E-HICH channel, obtains two parts data message, is b H, 0, ..., b H, 39, and b H, 40..., b H, 79And b H, 0, ..., b H, 39And b H, 40..., b H, 79, and be positioned at the middle idle bit position of two parts data message; The replacement sequence z that Node B will preset u(u=0...7) be substituted into the idle bit position of original series, generate replace after sequence d h, sequence d after replacing hBe { b H, 0, b H, 1..., b H, 39, z 0, z 1... z 7, b H, 40, b H, 41..., b H, 79.
Step 406, Node B send at the E-HICH channel and replace rear sequence to UE.
Sequence d after the replacement that step 407, UE reception send h, obtain the replacement sequence z that receives u'.
Concrete, sequence d after the replacement of UE reception E-HICH channel h, sequence d after will replacing hAfter carrying out despreading, demodulation, the replacement sequence that obtains receiving.
Step 408, UE adopt the mode of comparative sequences according to the replacement sequence that receives, and detect the E-HICH channel quality.
UE has obtained default replacement sequence by step 402, and the default replacement sequence that replacement sequence and the UE of reception are known compares by bit, replaces the correctness detection E-HICH channel quality of sequence according to transmission.
Concrete, above-mentioned correctness according to transmission replacement sequence detects E-HICH channel quality concrete steps as shown in Figure 6:
Step 601, comparison threshold Th1, Th2 are set.
Concrete, when Th1 〉=Th2,
When Th1＞Th2, be provided with two thresholdings, wherein Th1 is the first channel thresholding, Th2 is the second channel thresholding;
When Th1=Th2, namely be equivalent to be provided with a thresholding.
The replacement sequence of the idle bit position of the replacement original series that step 602, UE will receive compares with the default replacement sequence of knowing, adds up the number of bits n that two sequence corresponding bit position values equate.
Concrete, the replacement sequence of the idle bit position of the replacement original series that will receive as UE and default replacement sequence are relatively the time, start counter, when the replacement sequence of the idle bit position of the replacement original series that reception is arranged equates with the value of default replacement sequence corresponding bit position, rolling counters forward is added up the number of bits n that two sequence corresponding bit position values equate.When sequence relatively finishes, counter O reset.
Step 603, UE compare according to number of bits n and the thresholding that two sequence corresponding bit position values equate, thereby know that the E-HICH channel receives correctness.
Concrete, when Th1＞Th2, the result that obtains is any in following two kinds:
(a) when n 〉=Th1, it is correct that UE knows that the E-HICH channel receives;
(b) as n≤Th2, UE knows that the E-HICH channel receives mistake.
When Th1=Th2, the result that obtains is any in following two kinds:
(a) when n 〉=Th1=Th2, it is correct that UE knows that the E-HICH channel receives;
(b) as n＜Th1=Th2, UE knows that the E-HICH channel receives mistake.
Need to prove, when Th1=Th2=8, be complete matching detection, even the replacement sequence of the replacement original series idle bit position of reception equates fully with the replacement sequence corresponding bit position value of knowing, it is correct that UE knows that the E-HICH channel receives; Otherwise UE knows that the E-HICH channel receives mistake.
The embodiment of the invention uses default replacement sequence to replace in original series by Node B, compare according to the replacement sequence that receives and the replacement sequence of presetting by UE, and then detection E-HICH channel quality, realized that UE is to the detection of E-HICH channel quality in the situation that the E-HICH channel does not have CRC and is multiuser multiplexing
The embodiment of the invention provides a kind of detection method of E-HICH channel quality, be applied in HSPA system or the HSPA+ system, mode by the default replacement sequence of Node B definition, adopt the unspecified idle bit position of default replacement sequence replacing original series, UE will be by replacing Sequence Detection E-HICH channel quality, finish the down-going synchronous detection of loss of mains, and UE generates the power control word and it is reported to Node B according to the testing result of E-HICH channel quality, concrete steps as shown in Figure 7:
