Publication number: 20200252827Abstract: Techniques for use in a wireless device are provided. The techniques include monitoring a status of an amount of data in at least one buffer for transmission; determining an indication of additional capacity for transmission; transmitting at least one signal with an indication based on the monitored buffer status and the indication of additional capacity for transmission; and transmitting data of the at least one buffer based on the transmitted at least one signal.Type: ApplicationFiled: April 20, 2020Publication date: August 6, 2020Applicant: Signal Trust for Wireless InnovationInventors: Stephen E. Terry, Yi-Ju Chao

Patent number: 10631197Abstract: A system and method which improve the performance of a wireless transmission system by intelligent use of the control of the flow of data between a radio network controller (RNC) and a Node B. The system monitors certain criteria and, if necessary, adaptively increases or decreases the data flow between the RNC and the Node B. This improves the performance of the transmission system by allowing retransmitted data, signaling procedures and other data to be successfully received at a faster rate, by minimizing the amount of data buffered in the Node B. Flow control is exerted to reduce buffering in the Node B upon degradation of channel qualities, and prior to a High Speed Downlink Shared Channel (HS-DSCH) handover.Type: GrantFiled: October 2, 2017Date of Patent: April 21, 2020Assignee: Signal Trust for Wireless InnovationInventors: Stephen E.

Patent number: 10172048Abstract: A method and system for the UE and RNC to reduce transmission latency and potentially prevent loss of PDUs upon a MAC-hs layer reset. The RNC generates a radio resource control (RRC) message with a MAC-hs reset indication. The MAC reset indication requires the UE to flush buffers for configured HARQ processes, disassemble MAC protocol data units (PDUs) in the reordering buffers, deliver MAC-d PDUs to a MAC-d layer, and configure the MAC-hs to receive new data.Type: GrantFiled: April 4, 2016Date of Patent: January 1, 2019Assignee: InterDigital Technology CorporationInventors: Stephen E. Terry, Yi-Ju Chao

Publication number: 20170196017Abstract: A transmitting device may receive a radio link control (RLC) status report from a user equipment (UE) that indicates that a first RLC protocol data unit (PDU) is missing. The first RLC PDU may be multiplexed with a RLC PDU associated with a second priority to produce a second data block. The second priority may be higher priority than the first priority. The second data block may be transmitted using hybrid automatic repeat request (HARQ).Type: ApplicationFiled: March 21, 2017Publication date: July 6, 2017Applicant: InterDigital Technology CorporationInventors: Stephen E. Terry, Yi-Ju Chao, James M. Miller

Patent number: 9622257Abstract: The transmission and retransmission of radio link control (RLC) data protocol data units (PDUs) is managed by user equipment (UE). An indication is received, by the UE, that an RLC data PDU was not received by a receiving device. The RLC data PDU, that was not received, is retransmitted and prioritized over other RLC data PDUs. A number of times that the RLC data PDU was retransmitted is tracked by the UE.Type: GrantFiled: October 24, 2014Date of Patent: April 11, 2017Assignee: Interdigital Technology CorporationInventors: Stephen E.

Patent number: 9622066Abstract: A system and method which permit the RNC to control purging of data buffered in the Node B. The RNC monitors for a triggering event, which initiates the purging process. The RNC then informs the Node B of the need to purge data by transmitting a purge command, which prompts the Node B to delete at least a portion of buffered data. The purge command can include instructions for the Node B to purge all data for a particular UE, data in one or several user priority transmission queues or in one or more logical channels in the Node B, depending upon the particular data purge triggering event realized in the RNC.Type: GrantFiled: October 5, 2015Date of Patent: April 11, 2017Assignee: InterDigital Technology CorporationInventors: Stephen E.

Patent number: 9565603Abstract: A radio resource control (RRC) message is received by a radio resource control (RRC) device of a user equipment (UE). The RRC message notifies the FDD UE of a high speed dedicated shared channel (HS-DSCH) inter-Node B cell change. A reordering buffers of a medium access controller-high speed (MAC-hs) is flushed in response to the receiving the RRC message. A status report is generated for each acknowledge mode (AM) RLC instance mapped to the HS-DSCH by a radio link control (RLC) device after the MAC-hs flushes the reordering buffer. Each status report indicates missing AM RLC packet data units (PDUs). The RRC device sends a “TRANSPORT CHANNEL RECONFIGURATION COMPLETE” message on a DCCH after the RLC device generates each status report.Type: GrantFiled: December 21, 2015Date of Patent: February 7, 2017Assignee: Intel CorporationInventors: Yi-Ju Chao, Stephen E.
