Method and apparatus for transmitting and acquiring synchronization information block

A method of acquiring synchronization information blocks, applied to user equipment, the method comprising:

• detecting a synchronization information block carried by a high frequency beam according to a preset initial detection window;
• acquiring mode index information of an SS burst set from the detected synchronization information block, wherein the mode index information indicates a SS burst set mode, and the mode index information comprises information on a number of times that SS bursts with a same band are transmitted within one duration of an SS burst set and a number of times that SS bursts with the same band are comprised within one duration of the SS burst set;
• determining expected arrival times of subsequent synchronization information blocks according to the mode index information;
• and
• during subsequent signal synchronization processes, acquiring target synchronization information blocks according to the expected arrival times.

An apparatus for transmitting synchronization information blocks, comprising:

• a processor;
• and
• a memory for storing processor executable instructions;
• wherein the processor is configured to:
• determine target mode index information according to a preset SS burst set mode, wherein the target mode index information indicates the preset SS burst set mode, and the target mode index information comprises information on a number of times that SS bursts with a same band are transmitted within one duration of an SS burst set and a number of times that SS bursts with the same band are comprised within one duration of the SS burst set;
• store the target mode index information in each SS block to acquire target synchronization information blocks to be transmitted;
• and
• periodically transmit the target synchronization information blocks to user equipment in a target cell using high frequency beams;
• wherein each of the SS burst sets comprises a first preset number of SS bursts that are periodically transmitted;
• and each of the SS bursts includes a second preset number of the target synchronization information blocks that are transmitted in a spatial sequence.
