Abstract: The invention relates to link establishment in a wireless communication terminal. In order to obtain flexible and low power connections between a wireless terminal belonging to a short-range wireless network and an external wireless communication device not belonging to that network, a protection frame is sent either from the wireless communication terminal or from the external wireless communication device. The protection frame includes duration information used for virtual carrier-sensing in the short-range wireless network. In response to the protection frame, data is transferred between the wireless communication terminal and the external wireless communication device during a time period indicated by the duration information.

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: This document discloses a solution for transmitting scanning response messages in an orderly manner in a wireless network. An access node determines a transmission order for a plurality of access nodes responding to a scanning request message provided by a scanning/requesting device. Then, the access node determines its own transmission turn within the transmission order and transmits a scanning response message with reduced channel contention. Another aspect relates to the scanning device arranged to receive the scanning response messages where the scanning device monitors the transmission order of the scanning response messages.

Abstract: Embodiments of the present invention are directed to the invocation of active states and power conservation states in accordance with the standard or diluted beacon periods defined in beacon frames. Active periods, or “awake windows,” may be defined by additional information (e.g., information elements) that is included in the beacon. Awake windows may establish periods of time during which apparatuses may contend for access to a wireless communication medium. A methodology may further be employed to help determine which apparatuses will have priority when accessing the communication medium. This criteria may be used alone or in combination with the corresponding standard channel access rules (e.g., contention) that govern operation of the particular wireless communication medium in order to control how apparatuses communicate and interact in the wireless network.

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: 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.

Abstract: Method, apparatus, and computer program product embodiments are disclosed to improve network performance for ad hoc network initiation. Example embodiments include a new operational sequence for wireless devices initiating the use of an ad hoc network. The example embodiments require appropriately enabled wireless devices to only respond to probe request frames from other similarly appropriately enabled wireless devices. In this manner, two devices may avoid the time consuming effort of combining two different ad hoc networks into a single ad hoc network so that the two devices can communicate.

Abstract: Method, apparatus, and computer program product embodiments are disclosed to provide a wireless device with suitable operating parameters for wireless resource sharing with heterogeneous wireless networks to enable coexistence of secondary networks in a shared band environment. An example embodiment includes a method, comprising: receiving a request from a wireless network, requesting device management information for coexistence within an unassigned frequency band with zero or more neighboring wireless networks of the wireless network; and providing the requested device management information for the wireless network, based on at least location of the wireless network, the device management information including at least allowed frequency and transmission power.

Abstract: Method, apparatus, and computer program product embodiments are disclosed for independent wireless resource sharing on a fair basis to enable selecting the most suitable coexistence between wireless networks. Example embodiments of the invention include a hierarchical resource request process that enables reallocation of radio resources in a coexistence band. When new resources are requested by a network, a search is made for free resources in the coexistence band. If this does not succeed, a check is made for any allocated but unused resources in the coexistence band that have been advertised by neighboring networks. If there are insufficient advertised resources, then the allocation of resources in neighboring networks is analyzed and compared with the requesting network's need for network resources. There are two graduated stages to the analysis.
