Abstract
Provided are a random access method, UE and a storage medium. The method includes: performing, by a transmission device, random access on one uplink carrier of L uplink carriers configured in a cell, wherein the L is a positive integer greater than or equal to 1, and the uplink carrier includes at least one of the followings: a Non-Supplement Uplink (SUL) carrier and an SUL carrier.

A random access method, comprising:
- performing, by a transmission device, random access on one uplink carrier of L uplink carriers configured in a cell, wherein L is a positive integer greater than or equal to 1, and the uplink carrier comprises at least one of the followings:
- a Non-Supplement Uplink (SUL) carrier and an SUL carrier;
- wherein during a Physical Random Access Channel (PRACH) access process of the uplink carrier, in order to avoid the same Random Access-Radio Network Temporary Identity (RA-RNTI) for different UL carriers or different BWPs of each carrier, processing in at least one of the following manners:
- when different transmission devices transmit the Preamble code on same PRACH resources of different uplink carriers, processing via at least one of the followings:
- by carrying a carrier index in the RA-RNTI;
- by carrying a PRACH occasion index in the RA-RNTI;
- and
- by uniformly numbering PRACH frequency domain resources on the different carriers, f_ids used to calculate the RA-RNTIs on the different carriers being different in value or value range;
- when one carrier is configured with one or more Bandwidth Partials, BWPs, processing via at least one of the followings:
- by carrying a BWP index in the RA-RNTI;
- by carrying a carrier index in the RA-RNTI;
- by carrying a PRACH occasion index in the RA-RNTI;
- and
- by uniformly numbering PRACH frequency domain resources on different BWPs, f_ids used to calculate the RA-RNTIs on the different BWPs being different in value or value range;
- and
- when each carrier is configured with one or more BWPs during different carriers, processing via at least one of the followings:
- by uniformly numbering BWPs on the different carriers, and carrying a carrier index in the RA-RNTI;
- by carrying a BWP index in the RA-RNTI;
- by carrying a carrier index in the RA-RNTI;
- by carrying a PRACH occasion index in the RA-RNTI;
- and
- by uniformly numbering PRACH frequency domain resources of BWPs on the different carriers, f_ids used to calculate the RA-RNTIs on the different BWPs being different in value or value range.

User Equipment (UE), comprising:
- a communication module, configured to perform random access on one uplink carrier of L uplink carriers configured in a cell,
- wherein L is a positive integer greater than or equal to 1, and the uplink carrier comprises at least one of the followings:
- a Non-Supplement Uplink (SUL) carrier and an SUL carrier;
- wherein during a Physical Random Access Channel (PRACH) access process of the uplink carrier, in order to avoid the same Random Access-Radio Network Temporary Identity (RA-RNTI) for different UL carriers or different BWPs of each carrier, the UE is configured to process in at least one of the following manners:
- when different transmission devices transmit the Preamble code on same PRACH resources of different uplink carriers, processing via at least one of the followings:

- and
- by uniformly numbering PRACH frequency domain resources on different BWPs, f_ids used to calculate the RA-RNTIs on the different BWPs being different in value or value range;
- and
- when each carrier is configured with one or more BWPs during different carriers, processing via at least one of the followings:
- by uniformly numbering BWPs on the different carriers, and carrying a carrier index in the RA-RNTI;
- by carrying a BWP index in the RA-RNTI;
- by carrying a carrier index in the RA-RNTI;
- by carrying a PRACH occasion index in the RA-RNTI;
- and
- by uniformly numbering PRACH frequency domain resources of BWPs on the different carriers, f_ids used to calculate the RA-RNTIs on the different BWPs being different in value or value range.
