Publication number: 20210377964Abstract: The present invention is a method and apparatus for resource allocation signaling for grouping user real time services. Uplink signaling for voice activity reporting of each user's transition between an active state and an inactive voice state is sent from a wireless transmit/receive unit to a Node B. Radio resource allocation to users of a wireless communication system varies based on user measurement reporting, a pre-determined pattern such as frequency hopping, or a pseudorandom function. Grouping methods are adjusted to better utilize the voice activity factor, so that statistical multiplexing can be used to more efficiently utilize physical resources.Type: ApplicationFiled: March 20, 2012Publication date: December 2, 2021Applicant: Pantech Wireless, Inc.Inventors: Jin WANG, Arty Chandra, John S. Chen, Mohammed Sammour, Stephen E. Terry

Patent number: 11160058Abstract: 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.Type: GrantFiled: February 13, 2019Date of Patent: October 26, 2021Assignee: InterDigital Technology CorporationInventors: Stephen E.

Patent number: 11153475Abstract: A camera detects devices, such as other cameras, smart devices, and access points, with which the camera may communicate. The camera may alternate between operating as a wireless station and a wireless access point. The camera may connect to and receive credentials from a device for another device to which it is not connected. In one embodiment, the camera is configured to operate as a wireless access point, and is configured to receive credentials from a smart device operating as a wireless station. The camera may then transfer the credentials to additional cameras, each configured to operate as wireless stations. The camera and additional cameras may connect to a smart device directly or indirectly (for instance, through an access point), and the smart device may change the camera mode of the cameras. The initial modes of the cameras may be preserved and restored by the smart device upon disconnection.Type: GrantFiled: July 31, 2020Date of Patent: October 19, 2021Assignee: GoPro, Inc.Inventors: Richard T. Brockway, III, Jeffrey S. Youel, John S. Chen, Fabrice Barbier

Publication number: 20210112569Abstract: A method and a base station are disclosed. The base station comprises a transceiver and a processor. The base station transmits a radio resource control (RRC) message, wherein the RRC message indicates a resource block, the resource block including a plurality of locations indicating time-frequency orthogonal frequency division multiplex (OFDM) resource assignments for a plurality of wireless transmit/receive units (WTRUs), wherein different ones of the plurality of WTRUs search at different locations within the indicated resource blocks for assignment messages. The base station receives an uplink signal from a first WTRU from the plurality of WTRUs, wherein the uplink signal is based on one or more of the assignment messages for the first WTRU.Type: ApplicationFiled: December 22, 2020Publication date: April 15, 2021Applicant: Signal Trust for Wireless InnovationInventors: Jin Wang, Arty Chandra, John S.

Publication number: 20200351809Abstract: 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: July 21, 2020Publication date: November 5, 2020Applicant: InterDigital Technology CorporationInventors: Jin Wang, John S.
