Abstract

Apparatus, methods, and computer program products for full duplex communication are provided. An example method may include receiving a FDRA indication from a network entity, where the FDRA indication allocates a set of scheduling resources in a first band of a DL band or a UL band and includes an indication associated with a resource utilization in a second band of the UL band or the DL band, and where the DL band and the UL band overlap in a time domain. The example method may include receiving, from the network entity, a RRC configuration associated with a guard band between the UL band and the DL band. The example method may include communicating, with the network entity, a UL transmission or a DL transmission based on at least one of the set of scheduling resources, the guard band, or the resource utilization in the second band.
