Subband usage dependent downlink signals and channels

Abstract:

Methods, systems, and devices for wireless communications are described. A bandwidth part (BWP) configuration may be identified for a user equipment (UE), where the BWP configuration is part of a shared radio frequency spectrum band. In some cases, a base station may transmit a resource configuration for the BWP to the UE that indicates a set of subbands for the BWP and an indication of which subbands are available for the resource contention and possible subsequent communications. The UE and base station may determine a set of time-frequency resources for at least one downlink signal to be transmitted from the base station to the UE based on the BWP and available subbands. In some cases, the resource configurations for the BWP may include a reference signal configuration, a semi-persistent scheduling configuration, a control resource set configuration, or a combination thereof for the available subbands of the BWP.
