Abstract
A wireless communications system is described which comprises 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.

Circuitry for a base station for receiving wireless communications from a terminal device via a relay device, the circuitry comprising:
- transmitter circuitry configured to transmit, to the terminal device, an allocation of uplink resources for transmitting uplink data/control from the terminal device to the relay device;
- and
- receiver circuitry configured to receive the uplink data/control from the relay device on uplink resources allocated to the relay device for relaying the uplink data/control, wherein
- uplink data/control is transmitted to the relay device using the uplink resources allocated to the terminal device, and
- the uplink data/control transmitted from the terminal device on the allocated resources is received by the relay device and transmitted to the base station using the uplink resources allocated to the relay device.
A base station for receiving wireless communications from a terminal device via a relay device, the base station comprising:
- a transmitter configured to transmit, to the terminal device, an allocation of uplink resources for transmitting uplink data/control from the terminal device to the relay device;
- and
- a receiver configured to receive the uplink data/control from the relay device on uplink resources allocated to the relay device for relaying the uplink data/control, wherein
- uplink data/control is transmitted to the relay device using the uplink resources allocated to the terminal device, and
- the uplink data/control transmitted from the terminal device on the allocated resources is received by the relay device and transmitted to the base station using the uplink resources allocated to the relay device.
A method performed by a base station for receiving wireless communications from a terminal device via a relay device, the method comprising:
- transmitting, to the terminal device, an allocation of uplink resources for transmitting uplink data/control from the terminal device to the relay device;
- and
- receiving the uplink data/control from the relay device on uplink resources allocated to the relay device for relaying the uplink data/control, wherein
- uplink data/control is transmitted to the relay device using the uplink resources allocated to the terminal device, and
- the uplink data/control transmitted from the terminal device on the allocated resources is received by the relay device and transmitted to the base station using the uplink resources allocated to the relay device.
