Abstract: Aspects are provided which allow for a UE or a base station to handle CG or SPS occasions that fall in a partially full-duplex slot. Initially, the UE receives an indication of a configured grant (CG) or a semi-persistent scheduling (SPS) configuration for allocating CG or SPS occasions. Next, the UE determines whether the CG or SPS occasion overlaps in at least one SBFD symbol in a partially full-duplex slot based on the CG or SPS configuration. Afterwards, the UE communicates with a base station according to a modification to the CG or SPS occasion based on the CG or SPS occasion overlapping in at least one SBFD symbol in the partially full-duplex slot. As a result, the UE and the base station may handle instances where a CG or SPS occasion falls in a partially full-duplex slot without identifying an error conditions or simply dropping the CG or SPS occasion.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling that indicates a configuration for subband full duplex (SBFD) slots and a random access channel (RACH) configuration for SBFD slots. The UE may transmit at least one instance of a RACH message in an uplink subband of an SBFD slot in accordance with the RACH configuration. The RACH configuration may enable a UE to repeat a RACH message or transmit a multi-slot RACH message across an SBFD slot and an uplink slot. The RACH configuration may map synchronization signal blocks (SSB)s to RACH occasions in the uplink subband of the SBFD slot. In some examples, the SSBs may be mapped across multiple (e.g., consecutive) SBFD slots. In some cases, the RACH configuration may enable a UE to repeat a RACH message or transmit a multi-slot RACH message across multiple SBFD slots.

Abstract: To enable full-duplex communication in a time division duplexing (TDD) band, a network node (e.g., a user equipment (UE)) may be configured to communicate in one or more flexible bandwidth parts (BWPs) using BWP-specific TDD patterns regardless of a TDD pattern configured for the underlying band. However, in some cases, half-duplex communication may offer better performance than full-duplex communication (e.g., when full-duplex communication may cause self-interference or there is a need for high throughput half-duplex communication). Accordingly, some aspects described herein relate to timing considerations and switching indications for indicating an interval in which the network node is to operate in the flexible BWP using the BWP-specific TDD pattern and switching between the BWP-specific TDD pattern and the TDD pattern of the underlying band (e.g., using switching indications based on a number or quantity of transmission time intervals and/or a timer, among other examples).

Numerous other aspects are provided.
