Feedback Control in an FDD TDD-CDMA System
First Claim
1. A method for enabling active control feedback between a base station and user equipment (UE) in a wireless communications network, the method comprising:
- allocating 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;
allocating a second time slot within the frame 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; and
allocating other timeslots for the base station to operate in full duplex FDD mode.

Abstract
Active control feedback between a base station and user equipment in a wireless communications network is achieved by allocating a first time slot within a frame for a UE to transmit a beacon signal to the base station, where the beacon signal is separate from data signals in the frame, allocating a second time slot within the frame for the base station to transmit a control signal in response to the beacon signal, and allocating other timeslots for the base station to operate in full duplex FDD mode. The control signal provides a basis upon which the UE adjusts a transmission parameter, such as power.
