Classification: CPC H | IPC H

Claim 0:
1. A method implemented by a user equipment (UE) of a wireless communications system, wherein the method comprises:
sending, on a first time domain resource, a random access preamble to a base station of the wireless communications system, wherein a round-trip delay (RTD) between the UE and the base station is greater than a duration of a single slot;
obtaining a first index value of the first time domain resource;
obtaining an index difference between the first time domain resource and a second time domain resource based on the RTD, wherein the second time domain resource is for the base station to receive the random access preamble;
obtaining a second index value of the second time domain resource by adding the first index value and the index difference;
obtaining a random access radio network temporary identifier (RA-RNTI) based on the second index value;
receiving a random access response (RAR) from the base station; and
descrambling a cyclic redundancy check (CRC) code of the RAR using the RA-RNTI.
