Patent ID: 8009639

Claim:
A method for enabling active control feedback between a base station and user equipment (UE) in a wireless communications network, the method comprising: allocating, by a controller, a first time slot within a frame for a UE to transmit a beacon signal to the base station, wherein the beacon signal is separate from data signals in the frame, and includes uplink physical channel information; allocating, by the controller, a second time slot within the frame that is different to the first time slot for the base station to transmit a control signal in response to the beacon signal, the control signal for providing a basis upon which the UE adjusts a transmission parameter, wherein allocating the second time slot to the control signal comprises allocating the second time slot to the control signal using a first code of a code domain and allowing another downlink signal that is not the control signal to use a second code of the code domain to share the second time slot with the control signal, wherein the first code differs from the second code; and allocating, by the controller, other timeslots for the base station to operate in full duplex frequency division duplex (FDD) mode.
