Synchronization requests to reduce power consumption

摘要

An electronic device is described. In order to facilitate the communication of synchronization information with another electronic device in a wireless network, the electronic device provides a request for the synchronization information to the other electronic device at a time other than a predefined synchronization transmission time of the other electronic device. Then, the electronic device receives the synchronization information from the other electronic device in response to the request. In this way, the probability that the synchronization information is successfully communicated is increased, and the amount of time the electronic device is in an active mode is reduced, thereby reducing power consumption.

主权项

1. An electronic device, comprising:
an interface circuit configured to communicate with another electronic device; and a processor coupled to the interface circuit and configured to:
provide a request for synchronization information to the other electronic device at a time other than a predefined synchronization transmission time of the other electronic device;receive a first response containing the synchronization information from the other electronic device in response to the request;receive a second response from the other electronic device in response to the request, wherein the second response comprises pending traffic information; andkeep the interface circuit in a standby mode at the predefined synchronization transmission time of the other electronic device, thereby not transitioning to an active mode to receive beacon frames transmitted from the other electronic device at the predefined synchronization transmission time.
