Abstract: Various embodiments are described relating to selecting anchor nodes among nodes in a wireless network. In an example embodiment, a topological arrangement of a first wireless node and one or more other wireless nodes neighboring to the first wireless node in a wireless network may be determined by the first wireless node. A second wireless node may be selected to perform anchor node operations for the first wireless node based on the determined topological arrangement. For example, the first wireless node may select itself to perform the anchor node operations based on the determined topological arrangement.

Abstract: A method comprising determining information for the performance of a channel and sending the determined information to a transmitter is disclosed. The determined information can be sent to the transmitter with acknowledgement data. The determined information can include, for example, data rate and/or transmit power. The acknowledgement data can be sent in an acknowledgement frame, such as a block acknowledgement frame or immediate acknowledgement frame. The determined information can be sent in the payload of the frame. The frame can, for example, be a kink feedback frame associated only with a particular transmitter and receiver. A characteristic of the channel, such as signal and interference to noise ratio, can also be determined.

Abstract: A first device receives a request from a remote device to relinquish at least a portion of an existing reservation in a wireless communications network (e.g., a WiMedia network). The existing reservation is between the first device and a second device. Also, the existing reservation was initiated by the second device and includes a first allocation of resources of the wireless communications network. The first device forwards the request from the first device to the second device, and sends to the second device information indicating a current view of resource utilization in the wireless communications network. This view is from a perspective of the first device. Also, first device may receive a request from the second device for a second allocation of resources of the wireless communications network between the first device and the second device. Such a request may be based on the resource utilization information provided by the first device.

Abstract: Various embodiments are described relating to sharing scanning operations among nodes in a wireless network, such as a WiMedia ultra-wideband (UWB) network. In an example embodiment, a message may be sent from a first node to one or more other nodes in a wireless network indicating that the first node is configured to perform a scanning operation on a wireless medium in substitution of scanning the wireless medium at the one or more other nodes. The wireless medium may be scanned, for example, by the first node to obtain scanning results for the one or more other nodes. The scanning results may be sent, for example, by the first node, to the one or more other nodes.

Abstract: A method and apparatus for enabling a network to provide information associated with neighboring network(s) of different access technologies to the wireless device, prior to the wireless device determining the need for a handover. When a determination is made by the network that a handover to a new access network is required, the network may send a message to the wireless device that commands the wireless device to leave a currently used access network. Alternatively, the network may send a message to the wireless device that guides or obligates the wireless device to select one of the access networks in the list, provided by the network, in case the wireless device chooses to make a handover. Upon receipt of a command message, the wireless device leaves a currently used access network either immediately or a reasonable time after having set up a connection to a new access network for ensuring smooth handover.

Abstract: The present invention provides techniques for responding to overlapping conditions in wireless communications networks include receiving data transmissions from a transmitting device across a wireless communications network. These data transmissions correspond to a connection with the transmitting device and occur within a reserved portion of a communications resource. An interference condition is detected that includes an allocation of the communications resource for a neighboring device that overlaps with the reserved portion. Based on this detection, the method sends a notification to the transmitting device, the notification indicating the presence of overlapping transmissions in the reserved portion of the communications resource.

Abstract: A method, apparatus, and computer program product are disclosed for wireless communications networks, such as WiMedia networks, to solve problems of channel congestion, searching for candidate channels to select, and achieving reliable channel changes that will be recognized by other devices in the network. A wireless communications device selects a channel finding technique in a first stage, based on whether the device has any active connections in a current channel. The device then performs the selected channel finding technique with a plurality of channels to find a candidate channel. Then the initiating device sends a request to at least one remote device to change its channel from the current channel to the candidate channel during a time slot within a repeating time interval. If the request is successful, the initiating device receives an acceptance of the request from the remote device.

Abstract: In a wireless communications network, data of a first data stream is transmitted during a first portion of a repeating time period, the first data stream with at least one remote device. Also control information is transmitted during a second portion of the repeating time period, the control information including an identifier of the first data stream. A predetermined time interval is observed in which the transmission of a second data stream to the at least one remote device using the reserved identifier is prohibited. This time interval follows termination of the first data stream. Also, when receiving such transmissions, the data stream is considered active until the identifier of the data stream is missing from the second portion of the repeating time period for at least a predetermined time interval.
