A user equipment (UE) may transmit to a base station a first indication of a switching latency for transitioning between a half-duplex mode and a full-duplex mode. The UE may receive, from the base station in accordance with the first indication of the switching latency, a second indication that the UE is to transition to one of the half-duplex mode or the full-duplex mode. The UE may transition to the half-duplex mode or the full-duplex mode based on receiving the second indication.

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

A system includes a base band unit pooling component that determines, via a base band unit pool of base station devices, respective uplink channel estimates of an uplink channel wirelessly coupling, using frequency division duplexing via respective modular antenna elements, a user equipment to the base band unit pool.
