Methods, systems, and devices for wireless communications are described. A base station may indicate via control signaling a switching pattern for a bandwidth part (BWP) for communication between a user equipment (UE) and the base station. The switching pattern may include a set of slots associated with a full-duplex communications mode and a set of slots associated with a half-duplex communications mode. The UE and the base station may communicate in the half-duplex communications mode using the BWP, and the UE and the base station may communicate in the full-duplex communications mode using at least one of a first sub-BWP of the BWP for uplink signaling and a second sub-BWP of the BWP for downlink signaling. The base station may configure different resource allocations, operating parameters, and physical uplink control channel resources for the same configured transmissions or receptions for the half-duplex communications mode and the full-duplex communications mode.
