Controlling physical random access channel (prach) transmission power

A user equipment (UE), comprising:

• one or more non-transitory computer-readable media storing one or more computer-executable instructions for controlling physical random access channel (PRACH) transmission power;
• and
• at least one processor coupled to the one or more non-transitory computer-readable media, and configured to execute the one or more computer-executable instructions to cause the UE to:
• set a first power ramping counter to a first value;
• set a second power ramping counter to a second value;
• select a first random access channel occasion (RO) from a plurality of ROs associated with a single synchronization signal/physical broadcast channel (SS/PBCH) block;
• transmit a random-access (RA) preamble, to a base station (BS), in the first RO at a first PRACH transmission power;
• determine that an RA response (RAR) corresponding to the transmitted preamble is not received from the BS within a RAR window;
• select a second RO from the plurality of ROs associated with the single SS/PBCH block;
• determine whether the second RO is within a subband full duplex (SBFD) region in time domain;
• in a case that the second RO is within the SBFD region in the time domain:
• increment the first power ramping counter;
• and
• determine a current PRACH transmission power as a function of the first PRACH transmission power and the first power ramping counter;
• in a case that the second RO is not within the SBFD region in the time domain:
• increment the second power ramping counter;
• and
• determine the current PRACH transmission power as a function of the first PRACH transmission power and the second power ramping counter;
• and
• retransmit the RA preamble in the second RO at the current PRACH transmission power.
