Abstract:
1. A method for wireless transmission by using a frame structure supporting Relay, wherein time slots of a subframe is divided into a plurality of zones, and data transmission is performed in a time division multiplex manner, and the method further comprises: setting at least one time slot in the subframe as a hybrid zone; and performing the data transmission in a frequency division multiplex manner in the hybrid zone; wherein if a plurality of relays exist, a base station or a relay supports multi-hop by transmitting data, receiving data or being idle in a relay zone; wherein the multi-hop relay is supported partially in the following manner: in the downlink direction, an odd hop relay transmits data in a downlink relay zone of an even subframe to a next hop relay, and the base station and an even hop relay transmits data in a downlink relay zone of an odd subframe to a next hop relay; in the uplink direction, an odd hop relay transmits data in an uplink relay zone of an odd subframe to a back hop relay or base station, and an even hop relay transmits data in an uplink relay zone of an even subframe to a back hop relay; and wherein a relay supports multi-hop relay by operating in an intra-frame relay approach.
