Abstract

Embodiments of the present invention disclose a method, device, and user equipment for allocating a physical hybrid retransmission indicator channel, wherein the method for allocating a physical hybrid retransmission indicator channel includes: according to an extension parameter, a demodulation indicated in a physical downlink control channel PDCCH The reference signal cyclic shift value and the minimum index index value of the PRB of the physical resource block occupied by the uplink data transmission block are used to determine the PHICH index number corresponding to the uplink data transmission block. The extended parameters include cell-specific parameters and user equipment-specific parameters. parameter; allocate a PHICH to the uplink data transport block according to the PHICH index number. The physical hybrid retransmission indication channel allocation method, device and user equipment according to the embodiments of the present invention expand the adjustment range when the base station allocates the PHICH channel to the UE by extending the parameters and the cyclic shift value of the demodulation reference signal.

Description

Technical field

[0001] The present invention relates to the field of communication technology, and in particular to a method, equipment and user equipment for assigning a physical hybrid retransmission indicator channel. Background technique

[0002] In LTE (LongTerm Evolution, Long Term Evolution) technology, data transmission / reception supports HARQ (Hybrid Automatic Repeat Request) technology. The data receiver sends back ACK (acknowledgement) / NACK (Negative acknowledgement, Negative response) information to enable the data sender to confirm whether the data is correctly received by the data receiver.

[0003] Generally, the eNodeB (base station) will carry HARQ ACK or NACK information on the PHICH (Physical Hybrid ARQ Indicator Channel) allocated for the UE (User Equipment) to indicate whether the eNodeB correctly receives the UE transmission. Correspondingly, the UE needs to be able to determine the PHICH and obtain the ACK or NACK information for uplink data transmission thr...
