Abstract
Methods, systems, and devices are described for dealing with mutual clock drifts for communications over multiple RATs by maintaining a guard interval. A guard interval is a time interval during which no transmissions should occur. For example, the guard interval may be set relative to a scheduled interference interval of a STA so that transmissions to the STA from an AP will not collide with different RAT (e.g., interference) transmissions/receptions even with clock drift (e.g., a guard interval at both sides of the scheduled interference interval). Such an approach may allow the clocks to be re-synchronized (e.g., by the STA notifying the AP of the schedule of interference interval) infrequently to avoid excessive signaling overhead, which would increase with an increase in the number of coexistence STAs being serviced by the AP.
