1. A method performed by a User Equipment (UE) for performing uplink repetitions, the method comprising:
receiving a Reference Signal Received Power (RSRP) threshold from a Base Station (BS);
initiating a 4-step Random Access (RA) procedure;
performing a Downlink (DL) Reference Signal (RS) measurement to obtain an RSRP measurement result; and
performing a Message 1 (Msg1) repetition operation and a Message 3 (Msg3) repetition request operation within the 4-step RA procedure after determining that the RSRP measurement result is equal to or less than the RSRP threshold,
wherein:
the Msg1 repetition operation comprises transmitting a Msg1 for the 4-step RA procedure multiple times before the UE monitors a Random Access Response (RAR) corresponding to the Msg1, and
the Msg3 repetition request operation comprises transmitting a Msg3 repetition request to the BS to request execution of a Msg3 repetition operation, the Msg3 repetition operation comprising:
transmitting a Msg3 for the 4-step RA procedure multiple times in response to receiving the RAR.
