摘要： A method and system for dynamic adjustment of downlink/uplink resource allocation ratio in a long-term evolution (LTE) time division duplex (TDD) system is disclosed. The method includes replacing at least one uplink subframe in a subframe pattern with at least one of a mute subframe and a mute uplink pilot timeslot (UpPTS), within a geographical guard area that isolates at least two areas having different TDD allocation patterns. The method further includes scheduling an uplink transmission from at least one mobile terminal such that the at least one of the mute subframe and the mute UpPTS are unused. A simple solution or a TDD configuration index substitution solution, or any combination thereof, may be used to control the uplink transmission involving a mute subframe or a mute UpPTS.

摘要： A retransmission method for a time division duplexing self-adaptive frame structure, and a network side device relate to a technology of dynamically allocating uplink and downlink sub-frames in an LTE-advance (3GPP Release11) TDD communication system. The method comprises: during transmission of a TDD self-adaptive frame, for an uplink sub-frame, if a frame structure, of which an RTT period of PHICH and PUSCH of the uplink sub-frame is 10 ms, corresponding to the uplink sub frame is found in 7 types of defined frame structures, then sending PHICH data on a corresponding downlink sub-frame in the found frame structure, and sending retransmission data on the corresponding uplink sub-frame in the found frame structure. The solution ensures HARQ compatibility of an uplink data channel of R10UE. In addition, A/N feedback of the PDSCH is configured according to the uplink A/N resolution, thereby improving retransmission performance.
