Indication/report repetition information's procedure for PUCCH HARQ feedback for MSG4

A method of wireless communication of a user equipment (UE), comprising:

• performing at least one of
• a first determination of (a) whether a Bandwidth Part (BWP) selected for a random access procedure is configured with a set of random access (RA) resources indicating Msg3 repetition and Msg4 Hybrid Automatic Repeat Request (HARQ) acknowledgement (ACK) repetition as well as other RA resources not indicating Msg3 repetition or Msg4 HARQ ACK repetition and (b) whether a reference signal received power (RSRP) of a downlink reference signal is less than a threshold;
• and
• a second determination of whether the BWP is configured with the set of RA resources indicating the Msg3 repetition and the Msg4 HARQ ACK repetition and is configured with no other RA resources;
• in response to one of the first determination and the second determination being true, determining that both Msg3 repetition and Msg4 HARQ-ACK repetition are applicable for the random access procedure.

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

• a memory;
• and
• at least one processor coupled to the memory and configured to:
• receive, from a base station, a system information block (SIB);
• determine whether the SIB includes a set of candidate repetition factors for physical uplink control channel (PUCCH) transmissions;
• in response to determining that the SIB includes the set of candidate repetition factors:
• determine whether a reference signal received power (RSRP) threshold is included in the SIB;
• measure an RSRP of a downlink reference signal;
• and
• determine whether the measured RSRP is lower than the RSRP threshold when the RSRP threshold is configured in the SIB;
• transmit, to the base station in a message of a random access procedure, an indication of a capability of the UE for PUCCH repetition, wherein the indication of the capability is transmitted further in response to a determination that the measured RSRP is lower than the RSRP threshold;
• when the UE has the capability:
• determine a particular repetition factor based on at least one of the set of candidate repetition factors and a dynamic indication of a repetition factor;
• and
• transmit an acknowledgement (ACK) or negative acknowledgement (NACK) of a message 4 of the random access procedure in a PUCCH in accordance with the particular repetition factor.
