Methods and devices for wireless relays

摘要

A relay method and device, wherein the control signal and the data signal which are in the same subframe are directly sent to a lower level device respectively by an upper level device and a relay function device. In one example, the relay function device transmits data signal using subscriber special reference signal to make the lower level device estimate an access channel correctly; in another example, the relay function device carries out precoding of the data signal correlative with the access channel so as to cancel the influence of the access channel, thereby make the lower level device receive data signal correctly. Retransmission control signaling is sent to the lower level device in each subframe by the upper level device to ensure the fixed sequential relationship of feedback retransmission.

1. A method, in a first superior device, for communicating with a subordinate device, in cooperation with a second superior device, the method comprising:
sending controlling information directly to said subordinate device in a preset time unit, said controlling information instructing said subordinate device to receive data information at least from said second superior device in said preset time unit; determining transmission instruction information for said second superior device to transmit said data information to said subordinate device, said transmission instruction information instructing said second superior device to transmit said data information to said subordinate device in said preset time unit; and providing said transmission instruction information for said second superior device.
