Discovery-phase power conservation

摘要

The present specification describes techniques and apparatuses that enable power conservation in a wireless network. In some cases these techniques and apparatuses enable power conservation during a discover phase and for a wireless network subject to a government mandate requiring a device of the network to passively search for radar transmission prior to establishing communication with another device of the network.

主权项

1. A method comprising:
conserving power during a discovery phase of a wireless local area network (WLAN) by:
reducing power at an access point of the WLAN for a reduced-power-usage period, the access point operating in a geographical region and at a frequency in which client stations operating in the geographical region and at the frequency are required to passively search for radar transmissions prior to transmitting at the frequency, the reduced power being insufficient to enable the access point to receive communication from a client station within a communication region of the access point, the reduced-power-usage period at the access point being configured to vary according to information received by the access point from one of the client stations indicating a radar search period for the client station; andincreasing power at the access point subsequent to expiration of the reduced-power-usage period, the power being increased for a reception period in which communication from the client station or another client station within the communication region of the access point can be received.
