1. A method performed by a base station for transmitting a Synchronization Signal block (SS-block), said method comprising:
configuring the SS-block in a New Radio (NR) unlicensed spectrum, wherein the SS-block occupies x OFDM symbols, with x being a positive integer no greater than 4;
performing pre-transmission monitoring;
in response to having found, as a result of having performed the pre-transmission monitoring, that the channel is idle, transmitting an integral resource unit to a user equipment at a preset transmission timing, wherein the integral resource unit includes the SS-block and y OFDM symbols, y is zero or a positive integer, and the y OFDM symbols comprise a control resource set, and
in response to having found, as a result of having performed the pre-transmission monitoring, that the channel is busy, postponing the transmission of the integral resource unit and indicating a postponed time to the user equipment,
wherein one or more integral resource unit is configured to be transmitted in a measurement window, and the preset transmission timing for the one or more integral resource unit is set in preset OFDM symbols.
