  • Publication number: 20170367089
    Abstract: In a wireless communication system comprising at least one evolved Node-B (eNB) and a plurality of wireless transmit/receive units (WTRUs), a non-contention based (NCB) channel is established, maintained, and utilized. The NCB channel is allocated for use by one or more WTRUs in the system for utilization in a variety of functions, and the allocation is communicated to the WTRUs. The wireless communication system analyzes the allocation of the NCB channel as required, and the NCB channel is reallocated as required.

  • Patent number: 9780958
    Abstract: The present invention is related to a method and system for multi-cell coordination for multimedia broadcast multicast services (MBMS) in a wireless communication system. An MBMS multi-cell coordination unit is provided to coordinate a plurality of evolved Node-Bs (eNodeBs) for transmission of MBMS data synchronously in multiple cells of the same single frequency network (SFN). The MBMS multi-cell coordination unit may be located in an access gateway or in an eNodeB. An MBMS multi-cell scheduling scheme may be preconfigured for the eNodeBs for synchronization. Alternatively, the eNodeBs may be synchronized dynamically.

  • Publication number: 20170273021
    Abstract: A method and apparatus may be used for assigning groups of stations in wireless communications to one or more groups. Groups may be assigned by an access point (AP) based on information received from a station (STA). Group information may be signaled to each station and a group identifier may be indicated in a frame. The group information may be applied to a performance enhancement, for example power savings for the station, wherein the station enters a power saving mode on a condition that the station determines that it is not a member of the group.

  • Patent number: 9769843
    Abstract: A method and system for providing control information for supporting high speed downlink and high speed uplink packet access are disclosed. A Node-B assigns at least one downlink control channel and at least one uplink control channel to a wireless transmit/receive unit (WTRU). The downlink control channel and the uplink control channel are provided to carry control information for both the downlink and the uplink. Conventional control channels, for downlink and uplink are combined into a reduced set of control channels for uplink and downlink. The Node-B and the WTRU communicate control information via the downlink control channel and the uplink control channel. The WTRU receives downlink data and transmits uplink data, and the Node-B receives uplink data and transmits downlink data based on the control information transmitted via the downlink control channel and the uplink control channel.

  • Patent number: 9743422
    Abstract: A method and apparatus are provided for dynamic resource allocation, scheduling and signaling for variable data real time services (RTS) in long term evolution (LTE) systems. Preferably, changes in data rate for uplink RTS traffic are reported to an evolved Node B (eNB) by a UE using layer 1, 2 or 3 signaling. The eNB dynamically allocates physical resources in response to a change in data rate by adding or removing radio blocks currently assigned to the data flow, and the eNB signals the new resource assignment to the UE. In an alternate embodiment, tables stored at the eNB and the UE describe mappings of RTS data rates to physical resources under certain channel conditions, such that the UE uses the table to locally assign physical resources according to changes in UL data rates. Additionally, a method and apparatus for high level configuration of RTS data flows is also presented.

  • Publication number: 20170164362
    Abstract: A method and apparatus may be used for supporting multiple hybrid automatic repeat request (H-ARQ) processes per transmission time interval (TTI). A transmitter and a receiver may include a plurality of H-ARQ processes. Each H-ARQ process may transmit and receive one TB per TTI. The transmitter may generate a plurality of TBs and assign each TB to a H-ARQ process. The transmitter may send control information for each TB, which may include H-ARQ information associated TBs with the TBs. The transmitter may send the TBs using the associated H-ARQ processes simultaneously per TTI. After receiving the TBs, the receiver may send feedback for each of the H-ARQ processes and associated TBs indicating successful or unsuccessful receipt of each of the TBs to the transmitter. The feedback for multiple TBs may be combined for the simultaneously transmitted H-ARQ processes, (i.e., TBs).

  • Publication number: 20170156104
    Abstract: A method and apparatus may be used to broadcast a first beacon and a second beacon in a beacon interval. The first beacon may include an indicator that indicates whether a second beacon will be transmitted within the beacon interval. The first beacon may be a legacy beacon and the second beacon may be a non-legacy beacon. A legacy beacon may be decodable by any station (STA) and a non-legacy beacon may be decodable only by non-legacy STAs.

The gateway device may report information associated with the communication to a core network entity. The gateway device may receive a command message. The command message may include a request for a surveillance status of the device. The gateway device may send a response message. The response message may indicate a surveillance status of the device. The gateway device may receive an activate surveillance signal for the device. The gateway device may receive a deactivate surveillance signal for the device. Upon receiving the deactivate surveillance signal, the gateway device may stop further reporting.

  • Publication number: 20170117955
    Abstract: A wireless transmit receive unit (WTRU) and method are provided that process communication data in a hierarchy of processing layers including a physical (PHY) layer, a medium access control (MAC) layer and higher layers. A MAC layer transport format selection device defines an assignment of higher layer transmission data to parallel data streams based on data characteristics received from higher layers and physical resource information received from the PHY layer. The transport format selection also device generates transport format parameters for each data stream. A multiplexer component multiplexes the transmission data onto the parallel data streams in transport blocks in accordance with the data stream assignment and the respective transport format parameters generated by the transport format selection device and outputs the selectively multiplexed transmission data to the PHY layer for transmission over respective physical resource partitions.

  • Publication number: 20170063440
    Abstract: A method for taking measurements with a smart antenna in a wireless communication system having a plurality of STAs begins by sending a measurement request from a first STA to a second STA. At least two measurement packets are transmitted consecutively from the second STA to the first STA. Each measurement packet is received at the first STA using a different antenna beam. The first STA performs measurements on each measurement packet and selects an antenna beam direction based on the measurement results.
