Abstract: A method, apparatus, and computer program is presented for scanning in a wireless network. A wireless device receives a downlink frame from two access points, the downlink frames indicating their respective transmission powers. The wireless device then determines the closest access point and a transmission power sufficient to reach that access point. Then, the wireless device carries out transmission of a probe request with the determined transmission power.

Abstract: In one aspect thereof the invention provides a method that includes transmitting from a first (beaconing) mesh point at least one multicast or broadcast frame; and transitioning the first mesh point to a lower power mode of operation state after expiration of a specified post groupcast time from a last multicast or broadcast frame that was transmitted by the beaconing mesh point after expiration of an awake window, or when the awake window expires, whichever occurs later. In another aspect thereof the invention provides a method that includes operating a peer mesh point in an awake state; and maintaining the peer mesh point in the awake state for no more than a specified post groupcast time after a last target beacon transmission time, or a last received beacon frame, or a receipt of multicast or broadcast frame having an indication that another multicast or broadcast frame will be transmitted. A computer-readable medium storing program instructions to implement the methods is also disclosed, as are corresponding apparatus.

Abstract: The present document provides a method, apparatus, and computer program for determining, in a communication device of a first basic service set comprising a group of communication devices of a wireless telecommunication network, a primary channel of a second basic service set different from said first basic service set. Thereafter, the communication device causes transmission of channel identification information defining a location of at least one channel of the first basic service set from the communication device to the second basic service set on the determined primary channel of the second basic service set.

Abstract: Systems and techniques for wireless communication. A user device belonging to a group of user devices that may operate as wireless nodes configures a locale parameter based on its sensing of a radio channel. The locale parameter is included in a message readable by members of the group. A group member receiving a message determines a locale parameter based on its own sensing of a radio channel and responds to a received message only if the locale parameter in the message matches the locale parameter based on the sensing of the radio channel by the receiving member within specified bounds.

Abstract: Apparatuses may stay synchronized with a network via a beacon signal that is transmitted at a set interval. Various communication-related activities may be planned around an instance when a beacon signal is expected, or a target beacon transmission time (TBTT). While some networked apparatuses are active during every TBTT, other apparatuses may operate using a diluted beacon period that is an integer multiple of the network beacon signal interval. Diluted beacon intervals may initiate periods of time during which apparatuses may become “aware” of other apparatuses. Awareness may comprise information related to communication configuration, apparatus status, and services offered by the various apparatuses in the network. Awareness information obtained during an awake window may also comprise information on data-related tasks that are pending in one or more apparatuses which may allow for the control of further data conveyance activities.

Abstract: Apparatus, methods and computer program products provide quality of service and power aware forwarding rules for mesh points in wireless mesh networks by monitoring frame flow to and from a first mesh point in the wireless mesh network; and in dependence on the monitored frame flow, setting a power management mode of the first mesh point. The first mesh point monitors, for example, the power save mode and mesh deterministic access status of peer modes and selects power save and frame transmission modes in dependence on the monitored information.
