Wireless communications system and method

摘要

A wireless communications system including a base station, a relay device, and a terminal device. The terminal device is operable to receive from the base station an allocation of uplink resources for transmitting uplink data to the relay device, and to transmit uplink data to the relay device using the uplink resources allocated to the terminal device. The relay device is operable to receive the transmitted uplink data from the terminal device on the allocated resources, to receive an allocation of uplink data resources for relaying the received uplink data to the base station, and to transmit the received uplink data to the base station using the uplink resources allocated to the relay device.

1. A relay device for wirelessly relaying data from a terminal device to a base station, the relay device comprising:
circuitry configured to
receive, from the terminal device, uplink data transmitted on resources allocated to the terminal device by the base station;set power control information for controlling a power level of a subsequent transmission from the terminal device to the relay device;add a relay header to the uplink data received from the terminal device, the relay header including the power control information; andtransmit the uplink data, including the relay header, to the base station using uplink resources allocated to the relay device.
