Abstract
Provided is a method for performing a random access procedure by a terminal in a wireless communication system. The method comprises the steps of: selecting a first beam having a quality equal to or higher than a preconfigured threshold value; transmitting a random access preamble to a base station via the first beam; adjusting the threshold value when it is determined that the random access procedure has failed; and reselecting a second beam having a quality equal to or higher than the adjusted threshold value.
Claims13
A method for performing a random access procedure in a wireless communication system, the method comprising:
- selecting a first beam among a plurality of beams having a quality of a first threshold value or higher;
- transmitting a random access preamble to a base station through the first beam;
- adjusting the first threshold value to a second threshold value due to a failure of the random access procedure;
- reselecting a second beam among a plurality of beams having a quality of the second threshold value or higher;
- and
- transmitting the random access preamble to the base station through the second beam, wherein the first threshold value is different from the second threshold value.
A user equipment (UE) configured to perform a random access procedure in a wireless communication system, the UE comprising:
- a memory;
- a transceiver;
- and
- a processor operatively connected to the memory and the transceiver,
- wherein the processor is configured to:
- select a first beam among a plurality of beams having a quality of a first threshold value or higher;
- transmit a random access preamble to a base station through the first beam;
- adjust the first threshold value to a second threshold value due to a failure of the random access procedure;
- reselect a second beam among a plurality of beams having a quality of the second threshold value or higher;
- and
- transmitting the random access preamble to the base station through the second beam, wherein the first threshold value is different from the second threshold value.
