Abstract
Provided are a method for a terminal adjusting a random access backoff parameter in a wireless communication system, and a device supporting same. The method may comprise the steps of: receiving priority information; initiating a random access procedure while executing a handover; receiving, from a base station, a random access response including a backoff indicator; and on the basis of the priority information, adjusting a random access backoff parameter indicated by the backoff indicator.

A method for transmitting, by a user equipment (UE), a random access preamble in a wireless communication system, the method comprising:
- receiving a radio resource control (RRC) message including a scaling factor for prioritized random access procedure, from a base station;
- initiating a random access procedure for a handover;
- receiving a random access response including a backoff indicator related to a first random access backoff parameter value, from the base station;
- based on (i) the random access procedure being initiated for the handover, and (ii) the scaling factor being configured in the RRC message, setting a second random access backoff parameter value to the first random access backoff parameter value multiplied with the scaling factor included in the RRC message;
- and
- transmitting the random access preamble to the base station, based on the second random access backoff parameter value.
A user equipment (UE) configured to transmit a random access preamble in a wireless communication system, the UE comprising:
- at least one memory;
- at least one transceiver;
- and
- at least one processor connected with the at least one memory and the at least one transceiver, wherein the at least one processor is configured to:
- control the at least one transceiver to receive a radio resource control (RRC) message including a scaling factor for prioritized random access procedure, from a base station,
- initiate a random access procedure for a handover,
- control the at least one transceiver to receive a random access response including a backoff indicator related to a first random access backoff parameter value from the base station,
- based on (i) the random access procedure being initiated for the handover, and (ii) the scaling factor being configured in the RRC message, set a second random access backoff parameter value to the first random access backoff parameter value multiplied with the scaling factor included in the RRC message, and
- control the at least one transceiver to transmit a random access preamble to the base station, based on the second random access backoff parameter value.
