Abstract
Provided is a method and device for transmitting and receiving a Synchronization Signal block (SS-block). The method for transmitting the SS-block includes: configuring the SS-block in an NR unlicensed spectrum, wherein the SS-block occupies x OFDM symbols, with x being a positive integer no greater than 4; and transmitting the S S-block to a user equipment with a preset or configured subcarrier spacing. By this method, during the configuration of SS-block, the SS-block occupies x Orthogonal Frequency Division Multiplexing symbols. If the SS-block occupies a relatively small number of symbols, it is possible to reduce the duty cycle of DRS. In other words, it is possible to shorten the transmission duration of the SS-block, so as to reduce the time that the SS-block occupies the channel in the unlicensed spectrum.
