Uplink resource allocation for relay node based communication

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 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 wireless communications system, comprising:
a base station; a relay device; and a terminal device; wherein the terminal device is operable
to receive from the base station an allocation of uplink resources for transmitting uplink data to the relay device;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 resources for relaying the received uplink data to the base station;to add a relay header to the uplink data received from the terminal device, the relay header comprising control information for controlling the transmission of subsequent messages from the terminal device to the relay device; andto relay the received uplink data having the relay header added to the base station using the uplink resources allocated to the relay device.
