1 is closed, wherein
It include SRS resource 0 and 2 in SRS resource set 0；The corresponding time offset of SRS resource set 0 is 4；
It include SRS resource 1 and 3 in SRS resource set 1.The corresponding time offset of SRS resource set 1 is 8；
By executing step S130, determine that the corresponding sending time of SRS resource set 0 is time slot n+4；
Determine that the corresponding sending time of SRS resource set 1 is time slot n+8.
Meanwhile determining that time window is 2 time slots, the initial time of time window are as follows: distance receives the first SRS and triggers shape
The time that state indicates information, (time slot n) was spaced shortest sending time (time slot n+4)；The end time of time window is time slot n+6,
By executing step S140, since the corresponding sending time of SRS resource set 0 is time slot n+4, (risen in time window
Time beginning is time slot n+4；End time is time slot n+6) in；
The corresponding sending time of SRS resource set 1 is time slot n+8, and in time window, (initial time is time slot n+4；At the end of
Between be time slot n+6) outside, therefore, step S140 specifically may is that
SRS resource set 0 is sent in time slot n+4；SRS resource set 1 is not retransmited in time slot n+8.
