Abstract
Certain aspects of the present disclosure provide techniques for a physical downlink control channel (PDCCH) ordered random access channel (RACH) procedure. The RACH procedure may be associated with a cell-defining synchronization signal block (SSB) or non-cell-defining SSB. A method for wireless communications by a user equipment (UE) includes transmitting an indication of one or more capabilities of the UE, receiving a PDCCH that orders the UE to perform a RACH procedure on an uplink carrier based on the one or more capabilities of the UE, determining a minimum gap between a last symbol of the PDCCH and a first symbol of a RACH message, wherein the minimum gap includes a half-duplex (HD) switching delay, and performing the RACH procedure on the uplink carrier when a gap between the last symbol of the PDCCH and the first symbol of the RACH message is equal to or larger than the minimum gap.
