A method for wireless communication at a user equipment, UE, comprising: identifying, by the UE, support for full-duplex communications using one or more radio frequency spectrum bands, the full-duplex communications being associated with uplink resources (305-c) that overlap in time with downlink resources and separated from the downlink resources by a guard band; identifying a guard band configuration for separating first control signaling and first data signaling over the uplink resources (305-c) from second control signaling and second data signaling over the downlink resources based at least in part on the support for the full-duplex communications, wherein the guard band configuration indicates a variable guard band configuration based at least in part on one or more communication parameters, one or more configurations, or a combination thereof, and wherein identifying the guard band configuration comprises: identifying a beam configuration for communicating with a base station, wherein the guard band configuration is based at least in part on the beam configuration, or identifying an antenna panel configuration for communicating with the base station, wherein the guard band configuration is based at least in part on the antenna panel configuration; and transmitting, while simultaneously receiving, one or more messages to the base station using the one or more radio frequency spectrum bands based at least in part on the guard band configuration. identifying, by the UE, support for full-duplex communications using one or more radio frequency spectrum bands, the full-duplex communications being associated with uplink resources (305-c) that overlap in time with downlink resources and separated from the downlink resources by a guard band; identifying a guard band configuration for separating first control signaling and first data signaling over the uplink resources (305-c) from second control signaling and second data signaling over the downlink resources based at least in part on the support for the full-duplex communications, wherein the guard band configuration indicates a variable guard band configuration based at least in part on one or more communication parameters, one or more configurations, or a combination thereof, and wherein identifying the guard band configuration comprises: identifying a beam configuration for communicating with a base station, wherein the guard band configuration is based at least in part on the beam configuration, or identifying an antenna panel configuration for communicating with the base station, wherein the guard band configuration is based at least in part on the antenna panel configuration; and identifying a beam configuration for communicating with a base station, wherein the guard band configuration is based at least in part on the beam configuration, or identifying an antenna panel configuration for communicating with the base station, wherein the guard band configuration is based at least in part on the antenna panel configuration; and transmitting, while simultaneously receiving, one or more messages to the base station using the one or more radio frequency spectrum bands based at least in part on the guard band configuration.
