摘要:
A machine-to-machine (M2M) gateway (GW) includes reachability, addressing, and repository (RAR) capability. The GW maintains a local mapping table and local device application repository, performs data aggregation, address/name translation, provides event reporting and establishes GW reachability and wake-up time. The GW supports requests from M2M applications or other capabilities within the GW, and from a network and application (N&A) domain RAR. The GW may include an M2M device and M2M gateway management (MDGM) capability that receives management requests for an M2M device and functions as a network proxy. The MDGM accepts and processes requests from the N&A domain on behalf of the M2M device and performs management functions of the M2M device on behalf of the N&A domain. The MDGM may request the N&A domain for permission to interact with the M2M device, initiate an interaction for device management tasks with the M2M device, and report to the N&A domain.
摘要:
A device and method for registering devices on advanced networks as well as providing operative communications between a legacy device and a advanced network. The legacy device may contain data, such as sensor data, which is being collected on a network outside the communication range/abilities of the legacy device. An intermediary device may receive the data via a first communication scheme and send the device to a server collecting the data via a second communication scheme.

A dynamic spectrum management (DSM) system includes a plurality of stations and a central entity. A plurality of different radio access technologies are deployed in the DSM system and the central entity coordinates and manages wireless communications in the network. A direct link station receives a beacon periodically from an access point (AP). The direct link station may receive a direct link synchronization message from the AP indicating that a following target beacon transmission time (TBTT) is a synchronization TBTT (STBTT). The direct link station may silence the direct link channels during the STBTT. The direct link station may perform carrier sense multiple access (CSMA) on a primary channel of the direct link to get an access to all direct link channels. A connectivity map procedure may be performed to establish a map for connectivity, services, or capabilities of the devices in the network.
摘要:
Techniques for sending an aggregated beacon in a cognitive wireless network are disclosed. A beacon device may segment beacon information and send beacon segments via a plurality of channels simultaneously. A certain information elements of the beacon information may be included in each beacon segment. Each beacon segment may include channel information for other beacon segments that are transmitted simultaneously. Alternatively, a discovery beacon may be transmitted in addition to a regular beacon. The discovery beacon may include information indicating an operating channel on which the regular beacon is transmitted. The discovery beacon may be transmitted using a predetermined channel bandwidth, with a smaller beacon interval than the regular beacon, or in a frequency hopping fashion. The discovery beacon may be sent on a channel selected based on a regulatory class and corresponding channel information. The discovery beacon may be transmitted on a side channel.

Method and apparatus having a beamforming antenna generates a plurality of directional antenna beams. A discovery beacon is generated for use in associating with a wireless transmit/receive unit (WTRU). The discovery beacon is transmitted to a plurality of sectors using coarsely focused directional antenna beams. A WTRU may receive one of the coarsely focused directional antenna beams, and may then transmit a response message. Finely focused directional antenna beams are establishing for packet data transmission. A periodic beacon may then be transmitted to the WTRU using one of the coarsely focused directional antenna beams.

摘要:
Methods and apparatus are described. According to a method, a wireless transmit/receive unit (WTRU) communicates with a base station using a first base station operating frequency and a set of cell configuration parameters. The WTRU receives information indicating a second base station operating frequency to use for communications with the base station at a given time. The WTRU communicates with the base station using the second base station operating frequency and the same set of cell configuration parameters on or after the given time.
摘要:
A method and apparatus for operating supplementary cells in licensed exempt (LE) spectrum. An aggregating cell operating in a frequency division duplex (FDD) licensed spectrum is aggregated with a LE supplementary cell operating in a time sharing mode for uplink (UL) and downlink (DL) operations. The LE supplementary cell may be an FDD supplementary cell dynamically configurable between an UL only mode, a DL only mode, and a shared mode, to match requested UL and DL traffic ratios. The LE supplementary cell may be a time division duplex (TDD) supplementary cell. The TDD supplementary cell may be dynamically configurable between multiple TDD configurations. A coexistence capability for coordinating operations between the LE supplementary cell with other systems operating in the same channel is provided. Coexistence gaps are provided to measure primary/secondary user usage and permit other systems operating in the LE supplementary cell channel to access the channel.
