Publication number: 20240098670Abstract: 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.Type: ApplicationFiled: November 29, 2023Publication date: March 21, 2024Applicant: InterDigital Technology CorporationInventors: Jin Wang, John S.

Patent number: 11889504Abstract: A wireless transmit/receive unit (WTRU) receives control information over a physical downlink control channel in a shared radio resource space monitored by the WTRU. The control information includes radio resource assignment information and an indication of whether the control information includes radio resource assignment information for an uplink shared channel or whether the control information includes radio resource assignment information for a downlink shared channel. The WTRU determines whether the control information is intended for the WTRU based on WTRU identity-masked (ID-masked) cyclic redundancy check (CRC) bits. The WTRU determines, based on the indication, whether the control information is for the uplink shared channel or whether the control information is for the downlink shared channel. The WTRU transmits data over the uplink shared channel based on the radio resource assignment information on a condition that the control information is determined to be for the uplink shared channel.Type: GrantFiled: July 1, 2021Date of Patent: January 30, 2024Assignee: InterDigital Technology CorporationInventors: Marian Rudolf, Stephen G.

Publication number: 20240032085Abstract: 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.Type: ApplicationFiled: October 5, 2023Publication date: January 25, 2024Applicant: InterDigital Technology CorporationInventors: Arty Chandra, Jin Wang, Mohammed Sammour
