Title:
METHOD AND DEVICE FOR PERFORMING CONGESTION CONTROL IN NR V2X
Document Type and Number:
WIPO Patent Application WO/2021/101305
Kind Code:
A1
Abstract:
Provided are a method for a first device to perform a wireless communication, and a device supporting same. The method may comprise the steps of: measuring a channel busy ratio (CBR) for a resource pool in a first slot; determining the power for transmitting a physical sidelink shared channel (PSSCH) in a second slot on the basis of the CBR measured in the first slot; and transmitting the PSSCH to the second device in the second slot on the basis of the power. The first slot is the N-th slot before the second slot, where N is a positive integer determined on the basis of subcarrier spacing (SCS) related to the PSSCH transmission.
