  • Patent number: 9591031
    Abstract: Systems, methods, and instrumentalities are described to implement reporting of surveillance information associated with a device. A gateway device may intercept a communication associated with the device. The gateway device may route the communication such that the communication bypasses a core network. 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: 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.

  • Patent number: 9564996
    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).

  • Patent number: 9515804
    Abstract: A method and apparatus for selecting multiple transport formats and transmitting multiple transport blocks (TBs) in a transmission time interval simultaneously with multiple hybrid automatic repeat request (H-ARQ) processes in a wireless communication system are disclosed. Available physical resources and H-ARQ processes associated with the available physical resources are identified and channel quality of each of the available physical resources is determined. Quality of service (QoS) requirements of higher layer data to be transmitted are determined. The higher layer data is mapped to at least two H-ARQ processes. Physical transmission and H-ARQ configurations to support QoS requirements of the higher layer data mapped to each H-ARQ process are determined. TBs are generated from the mapped higher layer data in accordance with the physical transmission and H-ARQ configurations of each H-ARQ process, respectively. The TBs are transmitted via the H-ARQ processes simultaneously.

  • Publication number: 20160323906
    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: 20160057808
    Abstract: A wireless transmit receive unit and method disclose processing 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 (TFSD) assigns 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 TFSD generates transport format parameters for each data stream. A multiplexer component multiplexes transmission data onto parallel data streams in transport blocks according to data stream assignment and transport format parameters generated by the TFSD and outputs the selectively multiplexed transmission data to the PHY layer for transmission over physical resource partitions.

  • Publication number: 20150382317
    Abstract: A Node-B sends a polling message to a wireless transmit/receive unit (WTRU). The WTRU sends an uplink synchronization burst in response to the polling message without contention. The Node-B estimates an uplink timing shift based on the synchronization burst and sends an uplink timing adjustment command to the WTRU. The WTRU then adjusts uplink timing based on the uplink timing adjustment command. Alternatively, the Node-B may send a scheduling message for uplink synchronization to the WTRU. The WTRU may send a synchronization burst based on the scheduling message. Alternatively, the WTRU may perform contention-based uplink synchronization after receiving a synchronization request from the Node-B. The WTRU may enter an idle state instead of performing a handover to a new cell when the WTRU moves to the new cell. A discontinuous reception (DRX) interval for the WTRU may be set based on activity of the WTRU.

  • Publication number: 20150334736
    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.

  • Publication number: 20150319653
    Abstract: A method and system for performing handover in a third generation (3G) long term evolution (LTE) system are disclosed. A source evolved Node-B (eNode-B) makes a handover decision based on measurements and sends a handover request to a target eNode-B. The target eNode-B sends a handover response to the source eNode-B indicating that a handover should commence. The source eNode-B then sends a handover command to a wireless transmit/receive unit (WTRU). The handover command includes at least one of reconfiguration information, information regarding timing adjustment, relative timing difference between the source eNode-B and the target eNode-B, information regarding an initial scheduling procedure at the target eNode-B, and measurement information for the target eNode-B. The WTRU then accesses the target eNode-B and exchanges layer 1/2 signaling to perform downlink synchronization, timing adjustment, and uplink and downlink resource assignment based on information included in the handover command.

  • Patent number: 9167546
    Abstract: Providing discontinuous reception (DRX) is disclosed. In DRX mode a wireless transmit/receive unit (WTRU) may periodically wake up, in relation to a DRX interval, to check for a paging message. The WTRU may reenter the DRX mode if there is no paging message. The WTRU may receive another specified DRX interval, in connection with a broadcast message, based on the activity of the WTRU. The another DRX interval may be increased as inactivity of the WTRU increases.
