摘要： A method performed by a multiple radio-access technology (RAT) capable access point (AP), for communicating the direct link capability and RAT capability between a first station (STA) and a second STA is disclosed. The method may comprise the AP receiving a direct link discovery request message from the first STA using a first common enabled RAT. The AP may select a second common enabled RAT for communication with a second STA. The AP may forward the direct link discovery request message to the second STA using the second common enabled RAT. The first common enabled RAT and the second common enabled RAT may be the same. The AP may receive a direct link setup request message from the first STA using the first common enabled RAT and forward the direct link setup request message to the second STA using the second common enabled RAT.

摘要： A method and apparatus are described that provides flexible spectrum usage by using a paired frequency division duplex (FDD) spectrum to enable dynamic access in television white space (TVWS), sub-leased spectrum or unlicensed spectrum, (e.g., industrial, scientific and medical (ISM) bands), in a femto cell environment or the like. Elastic FDD (E-FDD) enables femto cell operation in TVWS, sub-leased spectrum and/or unlicensed spectrum, either simultaneously with licensed spectrum or as an alternate channel to licensed spectrum. E-FDD enables dynamic asymmetric bandwidth allocation for uplink (UL) and downlink (DL) in FDD, and enables variable duplex spacing, (i.e., using FDD with minimum duplex spacing between DL and UL spectrum, or, using hybrid-FDD, (FDD in a time duplexed fashion), when a spectrum gap between the UL and DL spectrum is below a certain minimum threshold. Additionally, the signaling enhancements to implement E-FDD are also provided.

摘要： A wireless transmit/receive unit (WTRU) may include one or more antennas and a first transceiver operatively coupled to the antennas. The one or more antennas and the first transceiver may be configured to receive a first signal from a network using zero energy from the WTRU. The one or more antennas and the first transceiver may be further configured to extract energy from the first signal. The first transceiver may be further configured to examine a separation between energy threshold events to decode an energy signature of the first signal. The first transceiver may be further configured to activate a second transceiver operatively coupled to the one or more antennas if the decoded energy signature matches a stored energy signature, wherein the second transceiver is powered by the WTRU. The one or more antennas and the second transceiver may be configured to receive a second signal from the network.

摘要： A method and apparatus are described for synchronizing a network. A plurality of existing nodes in the network may transmit beacons in accordance with a round-robin scheduling sequence. A new joining node may receive a beacon from a specific one of the existing nodes during a beacon interval, and transmit a join beacon frame during the beacon interval after waiting a random period of time. The specific existing node may receive the join beacon frame and transmit a notification to the other existing nodes in the network indicating that a new node is joining the network. Alternatively, the existing nodes may transmit a primary synchronization sequence (PSS) and a secondary synchronization sequence (SSS). After a new node receives the PSS and SSS from a specific one of the existing nodes, the new node may generate a random access channel (RACH) preamble indicating that it desires to join the network.

摘要： A wireless transmit/receive unit (WTRU) and a dynamic spectrum management (DSM) engine are described. The WTRU includes a transceiver, a radio frequency (RF) spectrum sensing unit and a processing unit. The transceiver transmits over a wireless link. The RF spectrum sensing unit measures information indicative of usage of a spectrum by other devices. The processing unit detects a change in performance of the wireless link. The processing unit also controls the transceiver to transmit a notification to a DSM engine indicating that the change in the performance of the wireless link was detected on a condition that the processing unit detects the change in performance of the wireless link. The processing unit also receives a sensing task request for the WTRU to measure the information indicative of the usage of the spectrum by other devices based on the notification transmitted to the DSM engine indicating that the change in the performance of the wireless link was detected.

摘要： A method and apparatuses for operation in a shared spectrum (SS) among a primary user (PU) and other users are disclosed. An access point (AP) or station (STA) may determine that a primary user is using SS frequency and only a portion of an 802.11 channel is available for AP/STA use. The AP may receive spectrum usage information of a PU from a database and transmit this information to a STA. The AP and STA may determine PU usage based on the information and change to a fractional spectrum mode. Based on PU usage, the AP and STA may adjust transmissions to suppress subcarriers used by the PU, including subcarriers in an SS-preamble, an SS short orthogonal frequency division multiplexing (OFDM) training field (SS-STF) symbol and an SS long OFDM training field (SS-LTF) symbol, and may reduce the physical (PHY) Layer Convergence Protocol (PLCP) Service Data Unit (PSDU) size.
