Downlink transmission indication for rach occasions

A method of wireless communication by a base station (BS), comprising:

• transmitting signaling to a user equipment (UE) including an indication of whether one or more random access channel occasions (ROs) will overlap with downlink transmissions in one or more periods of time;
• receiving, from the UE based on the indication, a random access channel (RACH) preamble in an RO of the one or more ROs during the one or more periods of time;
• and
• performing a RACH procedure with the UE based on the received RACH preamble.

An apparatus for wireless communication by a user equipment (UE), comprising:

• a memory and a processor coupled to the memory, the memory and the processor being configured to:
• receive signaling from a base station (BS) including an indication of whether one or more random access channel occasions (ROs) will overlap with downlink transmissions in one or more periods of time;
• transmit, to the BS based on the indication, a random access channel (RACH) preamble in an RO of the one or more ROs during the one or more periods of time;
• and
• perform a RACH procedure with the BS based on the transmitted RACH preamble.
