    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.

    Abstract: Access point functionality of a network device may be disabled, resulting in a coverage hole in a communication network and affecting performance of a client device. Various techniques can be implemented for detecting and minimizing coverage holes. In one embodiment, the network device can selectively establish a communication link with the client device depending on whether the client device is in a coverage hole and depending on whether the client device can detect another access point in the communication network. In some embodiments, the client device can determine that it is in a coverage hole in response to detecting a reserved SSID and can accordingly notify a central coordinator of the communication network. In some embodiments, the central coordinator can identify the network device (with disabled access point functionality) that can eliminate the coverage hole and can cause the network device to enable its access point functionality.
