Description
Technical field
The present invention relates to wireless communication field, relate in particular to a kind of transmission response feedback transmission of configuration information and response feedback method, system and equipment.
Background technology
Long Term Evolution (LTE) Frequency Division Duplexing (FDD) (FDD) system is used Physical Uplink Control Channel (PUCCH) form 1a/1b to carry out acknowledgement/non-acknowledgement (ACK/NACK) feedback transmission.LTE time division duplex (TDD) system is supported two kinds of different ACK/NACK feedback models: adopt the ACK/NACK merging patterns of PUCCH form (format) 1a/1b and the ACK/NACK multiplexer mode that adopts the PUCCH form 1b selecting in conjunction with channel.Long-term evolution upgrading (LTE-A) system is supported two kinds of ACK/NACK feedback models: adopt the pattern of the PUCCH form 1b selecting in conjunction with channel and the pattern that adopts PUCCH form 3.The concrete structure of above-mentioned PUCCH form is referring to TS36.211～213.
In LTE system, upstream control signaling is mapped in an ascending control channel (PUCCH) after by orthogonal sequence spread processing and transmits, and therefore on identical Physical Resource Block (PRB), can transmit a plurality of ascending control channels simultaneously.Each ascending control channel is corresponding a unique PUCCH resource number all, and UE can determine orthogonal spreading sequence that its corresponding ascending control channel is used and the PRB position at place by PUCCH resource number.PUCCH resource number can, by base station (eNB) configuration, also can be calculated by terminal (UE).
In LTE-A system, PUCCH transmission mode comprises single antenna port transmission pattern and transmit diversity transmission mode.When adopting single antenna port transmission pattern, by an antenna port, in corresponding PUCCH resource, send upstream data.
To disposing the UE of a plurality of transmitting antennas, can adopt transmit diversity transmission mode, while carrying out ascending control channel transmission, usage space orthogonal resource transmission difference (Spatial Orthogonal Resource Transmit Diversity, SORTD) mode realizes transmit diversity, thereby improves reliability or the capacity of upstream control signaling transmission.So-called SORTD, i.e. the corresponding PUCCH resource of each antenna port, identical information is carried out respectively after orthogonal spectrum expansion, by different antenna ports, in different PUCCH resources, sends simultaneously.Receiving terminal merges detection after separating from the signal of different antennae port, thereby obtains diversity gain.While being 2 antenna port shown in Fig. 1, use SORTD to carry out the schematic diagram of transmit diversity, wherein Tx0～Tx1 represents 2 transmitting antenna ports, and n_r0～n_r1 represents 2 different orthogonal spreading sequences corresponding to PUCCH resource, and s is feedback information.
In order to improve uplink control signaling reliability, in LTE system, base station can be carried out ACK/NACK by high-level signaling configuration UE and be repeated transmission.When carrying out ACK/NACK while repeating to transmit, UE is by the N continuous from Physical Downlink Shared Channel (PDSCH) or ACK/NACK feedback subframe corresponding to SPS resource release signaling
aNRepin individual sub-frame of uplink, repeat to feed back identical ACK/NACK information, wherein N
aNRepfor ACK/NACK number of repetition, by base station, by high-level signaling, configured.The rear N of transmission repeat ACK/nack message
aNRepin-1 sub-frame of uplink, do not transmit other any upward signals, the ACK/NACK information in its corresponding descending sub frame will not be transmitted.As shown in Figure 2, the ACK/NACK feedback subframe that descending sub frame n-4 is corresponding is sub-frame of uplink n, and UE repeats to send the ACK/NACK information that descending sub frame n-4 is corresponding, now N at sub-frame of uplink n～n+3
aNRep=4, and the corresponding ACK/NACK information of descending sub frame n-3～n-1 does not send.At sub-frame of uplink n+1, in n+3, the PUCCH resource that UE is used is configured by high-level signaling by base station.In addition at sub-frame of uplink n+1 in n+3, UE does not send other any upward signals.Standard regulation only has PUCCH format1a/1b to support ACK/NACK to repeat at present.
In realizing process of the present invention, inventor finds to exist in prior art following technical problem:
In LTE-A system, ACK/NACK feedback model, PUCCH transmission mode and ACK/NACK repeat etc. information by base station by the semi-static configuration of high-level signaling.Because semi-static configuration can not be adjusted according to the actual transmissions condition of UE and scheduling situation, therefore, for guaranteeing normal work, common semi-static configuration will adopt comparatively conservative configuration, guarantees that UE is in the normal work compared with under mal-condition.This has just caused UE, and in transmission conditions, the efficiency better or during scheduling low volume data is lower.
