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.
