The period of the time interval, the offset of the time interval, the length of the time interval, and the time slot where the time interval is located.

Exemplarily, the time slot where the time interval is located may be indicated by a gap slot bitmap (gapSlotBitmap). For example, the time slot corresponding to the first value in the interval time slot bitmap belongs to the time slot where the time interval is located, and the time slot corresponding to the second value in the interval time slot bitmap does not belong to the time slot where the time interval is located. time slot. Exemplarily, the first value is 1 and the second value is 0; or the first value is 0 and the second value is 1.
