Synchronization signal block transmitting and receiving method and device

A device for transmitting a Synchronization Signal block (SS-block), said device comprising:

• a memory and a processor, wherein the memory stores a computer program executable on the processor to cause the processor to configure 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;
• wherein the computer program, when executed on the processor, causes the device:
• to perform pre-transmission monitoring;
• in response to having found, as a result of having performed the pre-transmission monitoring, that the channel is idle, to transmit 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, to postpone the transmission of the integral resource unit and indicate 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.

A non-transitory computer readable storage medium storing thereon computer instructions, wherein the computer instructions when executed by a processor cause the processor:

• to configure 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;
• to perform pre-transmission monitoring;
• in response having found, as a result of having performed the pre-transmission monitoring, that the channel is idle, to transmit an integral resource unit to a user equipment at a preset transmission timing, wherein the integral resource united includes the SS-block and y OFDM symbols, wherein 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, to postpone 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 integral resource unit is set in preset OFDM symbols.
