Synchronization signal block transmission method and communication apparatus

An apparatus comprising:

• at least one processor;
• and
• at least one memory storing instructions executed by the at least one processor to cause the apparatus to perform operations of:
• receiving at least one of N synchronization signal blocks (SSBs);
• and
• determining a time position of a first SSB based on a number of the first SSB in the at least one SSB and a sending parameter, wherein the sending parameter is used to determine N candidate sending positions for transmitting the N SSBs in one periodicity T1, the N candidate sending positions are in at least two system frames, and the sending parameter comprises one or more of the following parameters:
• a sweeping periodicity T3, a quantity Y of candidate sending positions comprised in each system frame, a time interval T2 between two consecutive system frames of candidate sending positions comprised in each periodicity T1, and a quantity X of system frames of the candidate sending positions comprised in each periodicity T1, wherein T1, Y, T3, and T2 are positive integers, and N and X are integers greater than 1.
