Logical channels and scheduling request configurations for full-duplex modes and half-duplex modes
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration message indicating a scheduling request configuration that includes at least one resource associated with a half-duplex mode of the UE and at least one resource associated with a full-duplex mode of the UE. The UE may transmit a scheduling request using the at least one resource associated with the half-duplex mode or the at least one resource associated with the full-duplex mode. Additionally, or alternatively, the configuration message may indicate a logical channel that maps to a corresponding scheduling request configuration associated with a half-duplex mode of the UE, to a corresponding scheduling request configuration associated with a full-duplex mode of the UE, or to a combination thereof. Accordingly, the UE may transmit the scheduling request using the logical channel. Numerous other aspects are described.
