Abstract: An ad hoc network with distributed hierarchical scheduling is disclosed. In one aspect, stations in a network mesh detect interfering neighbor stations and form interference lists. Stations transmit their interference lists. Scheduling stations schedule allocations for child stations in response to interference lists, received remote allocations, or a combination thereof. Coordination messages are transmitted including frame structure, allocations, and interference lists, among others. In another aspect, an ad hoc mesh network may be organized into a tree topology. In an example wireless backhaul network, this matches traffic flow. Distributed, hierarchical scheduling is provided where parents schedule communication with children while respecting already scheduled transmissions to/from interferers and to/from interferers of their respective children.

Abstract: A method and apparatus for selecting one of a plurality of multi-band access points (APs) to associate with a multi-band wireless transmit/receive unit (WTRU) are disclosed. The multi-band APs broadcast frequency band information regarding multiple frequency bands on which the multi-band AP is configured to operate. The multi-band WTRU selects a particular multi-band AP to associate with and a frequency band to use to communicate with the selected multi-band AP based on the frequency band information. If the multi-band WTRU receives frequency band information from the selected multi-band AP which indicates that a characteristic, (e.g., throughput, path loss, load, capacity, backhaul), of the selected frequency band is unacceptable, the multi-band WTRU determines whether to disassociate with the selected multi-band AP or to continue to associate with the selected multi-band AP via a different frequency band.

Abstract: A method and apparatus are provided for a gateway which interconnects public safety wireless networks and commercial wireless networks that support push-to-talk group calls. The gateway translates Real Time Protocol (RTP), Session Invitation Protocol (SIP), and Talk Burst Control Protocol (TBCP)/Real Time Control Protocol (RTCP) messages received from the commercial wireless network and RTP and SIP messages received from the public safety wireless network into a format of the receiving network. The gateway has a call control component operable to set up and tear down RTP connections between the networks, a push-to-talk control component operable to arbitrate calls between wireless communications handsets of both networks, and a transmission control component operable to transfer media packets between the networks. The gateway reduces the number of call set ups required when a caller wants to speak because connections may remain active until the talk group participants leave the push-to-talk group call.

Abstract: The present invention provides method and systems for activating or deactivating network devices by managing the power of the network device. By controlling the power for network devices, the size and coverage of the network can be adjusted to meet the needs for the current usage. This can be particularly advantageous in wireless networks where multiple wireless access points may be provided to provide coverage during peak usage but present the additional security concern of the network being accessible to unauthorized users. Being able to power down unneeded wireless access points during off-peak usage allows for the minimization of such potential security concerns.
