Abstract

Disclosed are a method and a device for managing a beam in sidelink communication. An operation method of a first terminal comprises: a step for transmitting a first sidelink signal in all directions using a beam sweeping method in an initial beam management section; a step for receiving, from a second terminal, first feedback information for the first sidelink signal; a step for setting a first beam pair between the first terminal and the second terminal on the basis of the first feedback information; a step for performing sidelink communication with the second terminal using the first beam pair; and a step for, when it is necessary to reset the first beam pair, transmitting the second sidelink signal in a specific direction instead of all the directions using the beam sweeping method in a partial beam management section. Therefore, the performance of a communication system can be improved.

Description

technical field [0001] The present disclosure relates to side link communication technology, and more particularly, to beam management technology for configuring beam pairs between a transmitting terminal and a receiving terminal participating in side link communication. Background technique [0002] The fifth generation (5G) communication system (e.g., New Radio (NR) communication system) has been considered for processing wireless data, which uses a higher-than-fourth generation (4G) communication system (e.g., LTE) communication system or LTE-Advanced (LTE-A) communication system) higher frequency bands and 4G communication system frequency bands. The 5G communication system can support enhanced mobile broadband (eMBB) communication, ultra-reliable and low-latency communication (URLLC), massive machine-type communication (mMTC), etc. [0003] The 4G communication system and the 5G communication system may support vehicle-to-everything (V2X) communication. V2X communicat...
