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.
Claims18
A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
- receiving, from a base station, a scaling factor for prioritized random access;
- initiating a random access procedure;
- receiving, from the base station, a random access response comprising a backoff indicator;
- determining whether the random access procedure was initiated for a handover;
- based on a determination that the random access procedure was initiated for the handover, applying the scaling factor to the backoff indicator to set a random access backoff time;
- and
- transmitting, after the random access backoff time, a random access preamble to the base station.
A user equipment (UE) configured to operate in a wireless communication system, the UE comprising:
- at least one radio frequency (RF) module;
- at least one processor;
- and
- at least one computer memory operably connectable to the at least one processor and storing instructions that, when executed, cause the at least one processor to perform operations comprising:
- receiving, through the RF module and from a base station, a scaling factor for prioritized random access;
- initiating a random access procedure;
- receiving, through the RF module and from the base station, a random access response comprising a backoff indicator;
- determining whether the random access procedure was initiated for a handover;
- based on a determination that the random access procedure was initiated for the handover, applying the scaling factor to the backoff indicator to set a random access backoff time;
- and
- transmitting, through the RF module and after the random access backoff time, a random access preamble to the base station.
