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, 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.

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.

8. A controller for enabling active control feedback between a base station and UE in a wireless communications network, the controller comprising logic for:
-
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, and includes uplink physical channel information; allocating 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 DE 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; andallocating other timeslots for the base station to operate in full duplex frequency division duplex (FDD) mode. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A computer-readable storage medium comprising program code, executable by a processor, for enabling active control feedback between a base station and UE in a wireless communications network, the program code for:
-
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, and includes uplink physical channel information; allocating 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; andallocating other timeslots for the base station to operate in full duplex frequency division duplex (FDD) mode. - View Dependent Claims (16, 17, 18, 19, 20, 21)
