Abstract:
A network management node may manage a network of base stations and wireless transmit/receive units (WTRUs) that operate using diverse radio access technologies. The network management node may communicate with other network management nodes to manage spectrum usage across their respective managed networks. The network management node may acts as a proxy for cellular-capable WTRUs that operate within the managed networks. The network management node may perform handovers of Peer-to-Peer (P2P) groups that operate within the managed networks. The WTRUs may include WTRUs that operate at Very High Frequency (VHF) or Ultra High Frequency (UHF) spectrum ("white space") frequencies.
Abstract:
A method and apparatus for enabling multi-band transmission includes transmitting a beacon on a first radio band and transmitting the beacon on a second radio band. The beacon includes coordination information for transmission on the first and second radio bands.
Abstract:
Media independent handover (MIH) measurement and reporting in wireless communications. A periodicity for measurement and reporting is set on the MIH function through an MIH protocol message or an MIH_SAP primitive and on the link layer device through an MIH_LINK_SAP primitive. A new MIH-SAP primitive, MIH protocol message or MIH_LINK_SAP primitive is added to configure the periodicity. A new information element (IE) field for measurement reporting period may be added.
Abstract:
Metrics for estimating RF interference may be derived from measurements of idle channel noise, channel utilization, medium access delay, STA throughput, BSS throughput, and frame error rate. Further, metrics may be derived from the prior list of directly measured items in combination, as ratios and by rate of change analysis. RF interference is measured indirectly by measuring total idle channel power or by measuring changes in communication channel efficiency and frame errors.
Abstract:
An ultra wide band wireless transmit/receive unit (WTRU) communication includes a transmitter configured to transmit a first indicator of a multi-radio band transmission, and a receiver configured to receive a second indicator of a multi-radio band transmission.

Abstract:
In a wireless communication system including a (STA) including a basic service set (BSS) timer and in communication with a mesh access point (MAP), and a network management (NM) entity wherein the MAP and NM entity include a mesh timer, a method and apparatus for coordinating timing comprises the STA transmitting a BSS timer information message to the MAP, wherein the BSS timer information message includes a BSS timer value. The MAP receives the BSS timer information message and modifies the message. The MAP forwards the modified message to the NM entity.

Abstract:
In a wireless communication system comprising a plurality of mesh points (MPs) (110' 110"), a method for determining a level of involvement of MPs (110' 110") within the system includes a first MP (110') transmitting a network status request signal to a second MP (110"). The second MP (110") responds to the first MP (H110') with network status information. The first MP (110') receives the network status information from the second MP (110"), and determines a level of involvement in the wireless system (500) based on the network status information.
Abstract:
A method and apparatus for managing radio resources in one or more wireless communication networks. At least one radio resource manager (RRM) (106) is provided within a network node, or as an independent entity. The RRM (106) monitors performance on wireless communication links of the network(s) and interacts with nodes (102-1-102-n) associated with those links to change the configuration on a particular wireless communication link if its performance (i.e., quality) falls below an established threshold. Information regarding current resource usage of the network is sent to the RRM (106) by the nodes (102-1-102n). Each of the nodes (102-1102-n) may send a quality report to the RRM (106) including wireless communication link quality measurements and performance statistics.
