Abstract:
1. A method performed by a first access point configured to operate in first and second modes, the method comprising: outputting signals in the first mode, at least some of the signals containing communication data to be sent to a first device, at least some of the signals interfering with communication between a second device and a second access point, wherein, determining to operate the first access point in the second mode based on dynamically calculated values of one or more parameters that are related to signal interference at the second device, the one or more parameters comprising a signal-to-noise ratio; for a time period during which at least some of the communication data is scheduled to be sent from the first access point to the first device, operating the first access point in the second mode to improve communication at the second access point during at least part of the time period, wherein, in the second mode, the first access point outputs at least some of the communication data during the second period of time; and synchronizing operation of the first access point to operation of the second access point such that, for at least a period of time, the first access point operates in the second mode while the second access point operates in the first mode, or the first access point operates in the first mode while the second access point operates in the second mode, wherein synchronizing operation of the first access point is performed based on a pattern of change in mode of the second access point.
