  • Patent number: 10548159
    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: 20200029387
    Abstract: A wireless transmit/receive unit (WTRU) is disclosed that comprises a processor configured to selectively enable and disable reception of downlink signaling and configured to monitor a buffer of the WTRU for data to transmit. The WTRU comprises a transmitter configured to transmit, while reception of the downlink signaling is disabled, a channel allocation request in response to data in the monitored buffer. The processor is configured, in response to the data in the monitored buffer, to enable reception of the downlink signaling to allow the WTRU to receive an uplink channel allocation. The transmitter is configured, in response to the WTRU receiving an uplink channel allocation, to transmit uplink data on an uplink channel. The processor is configured to track a time when HARQ feedback is expected to be received in response to the transmitted uplink data, and configured to receive the HARQ feedback at the expected time.

  • Patent number: 10492154
    Abstract: A method and apparatus are described for controlling transmitter power in a wireless communication system in which channels, including one or more shared channels, are utilized. A wireless transmit/receive unit (WTRU) may receive a control signal from a base station. The WTRU may also receive a transmit power command from the base station. Further, the WTRU may transmit a shared channel signal to another WTRU in a transmission time interval (TTI) based on the control signal. The transmission power level of the transmitted shared channel signal may be based on the received transmit power command. Also, the transmission power level may be further based on a measured pathloss. In addition, the WTRU may transmit a second channel signal to the another WTRU in a TTI, wherein a transmission power level of the transmitted second channel signal is derived from a measured pathloss and a received transmit power command.

  • Publication number: 20190357167
    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.
