Abstract:
A technology of dynamically allocating uplink and downlink subframes in an LTE-advanced Time Division Duplex (TDD) communication system specifically relates to a TDD adaptive frame structure retransmission method, network and terminal side device. The method includes: in a TDD adaptive frame transmission process, for an uplink subframe, if a frame structure whose Round Trip Time (RTT) period of a Physical Hybrid-ARQ Indicator Channel (PHICH) and a Physical Uplink Shared Channel (PUSCH) corresponding to the uplink subframe is 10 ms is found in seven already defined frame structures, transmitting PHICH data on a corresponding downlink subframe in the found frame structure, and receiving retransmitted data on the corresponding uplink subframe in the found frame structure. The technical solution of the present application ensures the Hybrid Automatic Repeat Request (HARQ) compatibility with an uplink data channel of an R10UE.
