    Abstract: Logic for collision mitigation between transmissions of wireless transmitters and receivers operating at different bandwidths. Logic of the receivers may be capable of receiving and detecting signals transmitted at narrower bandwidths. In several embodiments, the receivers comprise a clear channel assessment logic that implements a guard interval (or cyclic prefix) detector to detect transmissions at narrower bandwidths. For instance, a two MegaHertz (MHz) bandwidth receiver may implement a guard interval detector to detect 1 MHz bandwidth signals and a 16 MHz bandwidth receiver may implement logic to detect one or more 1 MHz bandwidth signals and any other combination of, e.g., 1, 2, 4, 8 MHz bandwidth signals. In many embodiments, the guard interval detector may be implemented to detect guard intervals on a channel designated as a primary channel as well as on one or more non-primary channels.

    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.
