Description
Technical field
The present invention relates to the schemes of CA (Carrier Aggregation, carrier wave polymerization), more particularly to based on LTE
PHICH (Physical Hybrid-ARQ in the enhancing CA of (Long Term Evolution, long term evolution) system
Indicator CHannel, physical hybrid automatic repeat request indicator channel) resource allocation scheme.
Background technique
What traditional 3GPP (3rd Generation Partner Project, third generation cooperative partner program) was formulated
In LTE system R (Release, version) 10, CA is introduced into as one of key technology, and core concept is user equipment (UE-
User Equipment) it can work at the same time over a number of carriers, CA can be improved the peak rate of single UE.In LTE CA,
UE is configured a Pcell (Primary Cell, main serving cell), one or more Scell (Secondary Cell,
Auxiliary serving cell).For FDD (Frequency Duplex Division, frequency division duplex) LTE, a serving cell includes
At least one descending carrier in { descending carrier, a up-link carrier }.For TDD (Time Duplex Division,
Time division duplex) LTE, a serving cell includes a carrier wave.In LTE R10, the UE of CA is supported to be at best able to be configured 5 clothes
Business cell, and UE can only send PUCCH information on Pcell.In 3GPP R10, CA supports cross-carrier scheduling, i.e., base station is the
One carrier wave sends the wireless signal transmission on downlink signaling the second carrier wave of scheduling.Base station utilizes DCI (Downlink Control
Information, Downlink Control Information) in CIF (Carrier Indicator Field, carrier wave instructions field) instruction wanted
The target carrier of scheduling.CIF is by 3 bit indications positioned at the head DCI.
Pass through in the 66th plenary session (Plenary) of 3GPP RAN (Radio Access Network, wireless access network)
One new research topic (RP-142286), i.e. enhancing CA.Enhance in CA project, the serving cell number that maximum is supported rises to
32.
In LTE, it is used to indicate PUSCH (Physical Uplink Shared CHannel, Physical Uplink Shared Channel)
The HARQ_ACK whether signal is properly received is transmitted on downlink PHICH.In existing system, the PHICH that HARQ_ACK occupies is provided
Source is by (PHICH group number, the interior orthogonal sequence number of PHICH group) definition, and the PHICH group number is by DMRS (Demodulation
Reference Signal, demodulated reference signal) it indexes and PRB (Physical Resource Block, Physical Resource Block) rope
Draw common determination, likewise, orthogonal sequence number is also to be determined by the DMRS index and the PRB index in the PHICH group.
The DMRS index is the cyclic shift of DMRS corresponding to PUSCH, and the PRB index, which is PUSCH, transmits the of subframe at it
The index of occupied minimum PRB in one time slot.Transmission carrier wave and institute according to LTE standard, for the PHICH of PUSCH
The scheduling carrier wave for stating PUSCH is the same carrier wave.Therefore, a downlink (when a descending carrier dispatches multiple up-link carriers)
Multiple HARQ_ACK for multiple up-link carriers are likely to occur on carrier wave.For traditional LTE CA, the multiple HARQ_
The PHICH resource that ACK is occupied can avoid conflicting by selecting suitable DMRS index and PRB index.
Summary of the invention
32 carrier waves are at most directed to inventors discovered through research that may accommodate on a descending carrier in enhancing CA
HARQ_ACK, therefore a possibility that PHICH resource conflict, greatly increases.In addition, LAA (Licensed Assisted Access,
The access of authorization auxiliary) communication is a main application scenarios for enhancing CA, and in LAA communication, in order to meet supervision demand, one
UE may occupy most of PRB of upstream band (i.e. a possibility that PRB index conflict is higher).In summary two aspect
Reason, the existing PHICH resource method of salary distribution are not able to satisfy the demand of enhancing CA, it is therefore desirable to further enhance.
According to above-mentioned analysis, the invention discloses a kind of methods in UE, wherein includes the following steps:
Step A. sends the first wireless signal in first service cell
Step B. receives the HARQ_ACK for being directed to the first wireless signal.
Wherein, the PHICH resource that the HARQ_ACK is occupied is determined that the relevant parameter includes the first clothes by relevant parameter
The cell index for cell of being engaged in.
