Methods and devices for transmitting and receiving signals

Abstract

The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. Embodiments of the present disclosure provides method for transmitting signals on an Unlicensed Frequency Band (UFB), comprising: performing, by a transmitting node, a first type of Listen Before Talk (LBT) on a direction i; transmitting, by the transmitting node, signals on a direction j after passing the first type of LBT, wherein the direction i is omnidirectional, or one or multiple beam directions corresponding to the direction j. The technical scheme of the present disclosure may be applied to high-frequency-band signal transmission and LBT and avoid interference with other nodes on the UFB.
