It can be seen that predetermined threshold from attached drawing 9 and attached mapping mode shown in Fig. 10 and can be set to 21.Complete resource After mapping, the symbolic number differed between each synchronization signal block for belonging in the grouping of same synchronization signal block is less than predetermined threshold.Example Such as each synchronization signal block in the ss burst k in attached drawing 9 or attached drawing 10, ss block 1 and ss block 2 6 symbols are differed, ss block 1 differs 14 symbols with ss block 3, and ss block 1 differs 20 with ss block 4 Symbol, respectively less than predetermined threshold 21.For each synchronization signal block in the ss burst k+1 in attached drawing 9 or attached drawing 10, Ss block 1 differs 6 symbols with ss block 2, and ss block 1 differs 14 symbols, ss block with ss block 3 1 differs 20 symbols, respectively less than predetermined threshold 21 with ss block 4.
However, the symbolic number differed between each synchronization signal block belonged in different synchronization signal block groupings is more than predetermined Threshold value.Such as the ss block 4 in the ss burst k in the attached drawing 9 or attached drawing 10 and ss block in ss burst k+1 The distance between 1 recently, and the two differs 22 symbols, is more than predetermined threshold 21.
It is not interfere communication system in identical frequency band using attached using the advantages of attached resource mapping method shown in Fig. 10 Resource mapping method shown in Fig. 9 transmits data, avoids bringing with interior interference.
It optionally, similarly with 10 application scenarios of attached drawing, is to include 14 symbols for time slot used in communication system Time slot in the case where, can also at least have other 4 kinds of resource mapping methods.For brevity, only in one time slot Resource mapping method for be introduced.In the distribution mode in a synchronous signal impulse sending cycle between multiple time slots It is similar with attached drawing 10.The grouping of the first synchronization signal block is mapped on 2 continuous time slots, the second synchronization signal block is grouped It is mapped on other 2 continuous time slots, is separated by 1 time slot between this two groups continuous 2 time slots.It is wherein continuous at 5 In time slot, the resource mapping method in each time slot in the 1st, 2,4,5 time slot is respectively as shown in attached drawing 11-14.With attached drawing 10 similarly, in mapping scheme shown in attached drawing 11-14, in same synchronization signal block grouping between any two synchronization signal block The number of symbols at interval belongs to first set, the symbolic number being spaced between two synchronization signal blocks in different synchronization signal block groupings Mesh belongs to the second set not overlapped with first set, and the numerical value for including in first set is less than predetermined threshold, described The numerical value for including in second set is greater than predetermined threshold.Optionally, predetermined threshold can be set to 21.
