Title:
METHOD AND DEVICE FOR CONTROLLING TRANSMISSION POWER OF TERMINAL IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/206429
Kind Code:
A1
Abstract:
Disclosed are a communication technique which merges, with IoT technology, a 5G communication system for supporting a data transmission rate higher than that of a 4G system, and a system therefor. The present disclosure can be applied to intelligent services (for example, smart homes, smart buildings, smart cities, smart cars or connected cars, healthcare, digital education, retail, security- and safety-related services, and the like) on the basis of 5G communication technology and IoT-related technology. According to an embodiment of the present disclosure, provided is a method for a sidelink reception terminal in a communication system. The method comprises the steps of: receiving, from a base station, configuration information with respect to power control of physical sidelink feedback channel (PSFCH) transmission; receiving a plurality of scheduled physical sidelink shared channels (PSSCHs) on the basis of a plurality of sidelink control information (SCI) items; confirming one or more first PSFCHs on the basis of the number of scheduled PSFCHs and a maximum number of PSFCHs which can be transmitted by a first terminal in response to the reception of the plurality of PSSCHs; if the total transmission power of the one or more first PSFCHs is greater than the maximum transmission power of the first terminal, confirming one or more second PSFCHs in the descending order of priority indicated by the plurality of SCI items, wherein the number of one or more second PSFCHs is a maximum number of PSFCHs of which the sum of transmission power is less than or equal to the maximum transmission power; confirming first transmission power of each of the one or more second PSFCHs on the basis of the number of one or more second PSFCHs; and transmitting the one or more second PSFCHs on the basis of the first transmission power.
