Wireless device, method, and computer readable media for synchronization in a wireless local-area network
First Claim
1. A high-efficiency local-area wireless network (HEW) device, the HEW device comprising circuitry configured to:
- tune to a first subchannel based on a schedule received from an access point (AP) the schedule to indicate that the HEW device is assigned to the first subchannel;
determine a target beacon receive time;
tune to a second subchannel to receive a target beacon at the target beacon receive time;
receive the target beacon on the second subchannel, wherein the target beacon includes a network timer;
synchronize a local timer with the network timer; and
tune back to the first subchannel to continue to operate on the assigned first subchannel.

Abstract
Wireless devices, methods, and computer readable media for synchronization in a wireless local-area network. A method on a wireless communication device may include tuning to a first subchannel based on a schedule received from an access point (AP) the schedule to indicate that the HEW device is assigned to the first subchannel. The method may further include determining a target beacon receive time and tuning to a second subchannel to receive the target beacon at the target beacon receive time. The method may further include receiving the target beacon on the second subchannel and tuning back to the first subchannel. A method on an AP for synchronization may include transmitting information that indicates a target beacon receive time on a subchannel. The method may include not transmitting to a wireless communication device operating on a second subchannel for a period of time before the target beacon receive time, and transmitting a target beacon on a first subchannel at the target beacon receive time.
