Methods, systems, and devices for wireless communications are described. Example wireless communications systems may implement control signaling configuring a user equipment (UE) to communicate in a subband full-duplex (SBFD) mode. An SBFD mode may include a non-contiguous bandwidth part (BWP), and control signaling may indicate the resource blocks (RB)s included in the non-contiguous BWP. In some cases, the non-contiguous BWP may be for communications between the UE and the network in one communications direction (e.g., uplink or downlink), and another BWP may be configured for communications between the UE and the network in the other communications direction. The non-contiguous BWP may include two subbands, and the other BWP may be non-overlapping with (e.g., positioned between) the two subbands in the frequency domain. The network may configure a BWP time domain switching pattern (e.g., switching between SBFD and half-duplex modes according to a BWP time domain switching pattern).
