Method and apparatus for configuring random access occasion, method and apparatus for random access

A method of random access, being applied to UE, and comprising:

• receiving a current number of SSBs to be configured by a base station for sending and a number of ROs, and dividing the number of ROs by the current number of SSBs to obtain a remainder number;
• determining whether the remainder number is greater than or equal to a target number according to a configuration rule, wherein the target number is determined based on the current number of SSBs;
• in response to that the remainder number is greater than or equal to the target number, using a RO of a one-to-one correspondence with an SSB as a RO enabled for random access;
• and
• performing random access based on the RO enabled for random access.

User equipment, comprising:

• a processor;
• and
• a memory for storing instructions executable by the processor,
• wherein, the processor is configured to:
• receive a current number of SSBs to be configured by a base station for sending and a number of ROs, and divide the number of ROs by the current number of SSBs to obtain a remainder number;
• determine whether the remainder number of the number of ROs divided by a current number of SSBs is greater than or equal to a target number according to a configuration rule, wherein the target number is determined based on the current number of SSBs;
• in response to that the remainder number is greater than or equal to the target number, use a RO of a one-to-one correspondence with an SSB as a RO enabled for random access;
• and
• perform random access based on the RO enabled for random access.
