Abstract

The invention discloses a wireless communication system comprising a relay node and a base station, wherein the relay node is used for determining the uplink subframe configuration and the downlink subframe configuration of a return trip link; a downlink subframe m of the return trip link receives the uplink transmission order of the base station; the uplink subframe n (n=m+k, k is more than 0) of the return trip link sends the uplink data according to the uplink transmission order, wherein k represents the number of subframes. The base station sends the uplink transmission order to the relay node on the downlink subframe m of the return trip link and receives the uplink data transmission of the relay node on the uplink subframe n of the return trip link. The invention can realize the safety and reliability communication of the base station and RN.

Description

technical field [0001] The present invention relates to communication technology, in particular to a wireless communication method and system. Background technique [0002] In the existing communication system, the timing relationship between the uplink HARQ of the base station (eNB) and the user equipment (UE), that is, the Physical Hybrid ARQ Indicator Channel (PHICH, Physical HybridARQ Indicator Channel) and the Physical Uplink Shared Channel (PUSCH) is defined. , Physical UplinkShare Channel), and the timing relationship between a Physical Downlink Control Channel (PDCCH, Physical Downlink Control Channel) for sending uplink scheduling information and a scheduled PUSCH. [0003] The PHICH channel is used to transmit acknowledgment / denial (ACK / NACK) feedback information corresponding to the PUSCH channel, and the PUSCH channel is used to send uplink data packets. [0004] If PUSCH transmission is scheduled in uplink subframe #n, UE will PHICH PHICH is determined within,...
