Embodiment Construction

[0031] The operation of the current example embodiment and its structure are discussed in detail below. It should be appreciated, however, that the present disclosure provides many applicable inventive concepts that can be implemented in a wide variety of specific contexts. The specific embodiments discussed are merely illustrative of specific structures of the invention and specific ways for operating the invention, and do not limit the scope of the invention.

[0032] One embodiment relates to FD link adaptation in a full duplex (FD) communication system. For example, a communication controller performs the following operations: receiving a measurement report from a user equipment served by the communication controller, the measurement report indicating the first power margin between the current transmit power and the transmit power interruption point and the current transmit power and the ability to support the FD A second power margin between the maximum transmit power of...

Abstract

A method of operating a communications controller adapted for full duplex (FD) operation comprising: receiving a measurement report from a user equipment served by the communications controller, the measurement report indicating a current transmit power versus a transmit power A first power margin between interruption points and a second power margin between the current transmit power and the maximum transmit power capable of supporting FD operations; according to the first power margin and the second power margin performing FD link adaptation (link adaptation, LA) to adjust one or more FD configuration parameters of a link between the communication controller and the user equipment, wherein the link includes a downlink and an uplink a link; and instructing the user equipment to communicate over the link according to the one or more FD configuration parameters.

Description

[0001] Related Applications Cross Application [0002] This application requires that the invention submitted on August 4, 2015 be titled "System and Method For Full Duplex Link Adaptation In AFull Duplex Communications System" 14 / 818,030 ", the contents of which are incorporated herein by reference. technical field [0003] The present invention relates generally to digital communications and, more particularly, to a system and method for full-duplex link adaptation in a full-duplex communication system. Background technique [0004] In a full duplex (FD) device, the device transmits and receives simultaneously in a single frequency band. In other words, uplink and downlink transmissions occur simultaneously or in the same frequency band. Since an FD device does not have to wait until it has finished transmitting before receiving, or vice versa, as a half-duplex device does, spectral efficiency can potentially be doubled. Contents of the invention [0005] Example embo...
