Abstract
A wireless communications system includes a base station, a plurality of intermediate devices and a terminal device. The base station is operable to wirelessly transmit downlink signals to the terminal device, the downlink signals including terminal control signals identifying one of the intermediate devices as a target device to which the terminal device is to direct uplink signals intended for the base station. The terminal device wirelessly transmits the uplink signals to the base station via the intermediate device identified by the terminal control signals. In this way, downlink communications may be provided directly from the base station to the terminal device, including control signals which instruct the terminal device where to send uplink data. This enables the base station to directly control scheduling of uplink communications, and in particular to define the uplink route from the terminal device to the base station via one or more intermediate devices.
