12 Claims

1. A method for performing a beam management operation by a first user equipment (UE) in a wireless communication system supporting a direct communication between UEs comprising:

obtaining, from a second user equipment (UE), a measurement value for a quality of a beam pair which the direct communication between UEs is formed with the second UE; and

determining whether to perform a beam management operation for the beam pair based on at least one threshold value and the measurement value,

wherein each of the at least one threshold value is configured based on at least one of mobility information of the first UE, a relative speed to the second UE, a congestion level of a channel, and service characteristics related to the direct communication between UEs

wherein the beam management operation is performed based on the measurement value less than the at least one threshold value; and

wherein the beam management operation includes a first beam management operation in which beam sweeping is performed in a limited range based on a beam direction of the beam pair, and a second beam management operation in which the beam sweeping is performed regardless of the beam direction of the beam pair.
