Publication number: 20160029273Abstract: A method and wireless transmit receive unit (WTRU) are disclosed that is configured to perform cell reselection to another cell when the WTRU is in a CELL_FACH state using an Enhanced-Dedicated Channel (E-DCH). The cell reselection is based on internal measurements by the WTRU. Alternatively, the cell reselection can be WTRU based on the WTRU measurements reported to the network.Type: ApplicationFiled: October 5, 2015Publication date: January 28, 2016Applicant: Signal Trust for Wireless InnovationInventors: Diana Pani, Rocco DiGirolamo, Christopher R.

Publication number: 20160007303Abstract: A method and apparatus are used to determine an efficient transmit power for point to multipoint (PtM) transmissions by maintaining a database at a base station which specifies which of a plurality of wireless transmit/receive units (WTRUs) are members of each PtM group. The transmit power of each WTRU's downlink dedicated channel is adjusted to the minimum required power necessary and the PtM transmit power for each PtM group is set such that the PtM transmit power of a PtM group is equal to the greatest of a WTRU in the PtM group plus a PtM power offset.Type: ApplicationFiled: September 16, 2015Publication date: January 7, 2016Applicant: SIGNAL TRUST FOR WIRELESS INNOVATIONInventor: Stephen E.

Publication number: 20150381325Abstract: The present invention is related to a method and system for transferring wireless transmit/receive unit (WTRU)-specific information to support enhanced uplink (EU) operation in a wireless communication system. A radio network controller (RNC) obtains WTRU-specific information, and transfers the WTRU-specific information to the Node-Bs. Each Node-B is configured to schedule uplink transmissions from a WTRU and utilizes the WTRU-specific information in operation of EU transmissions.Type: ApplicationFiled: September 4, 2015Publication date: December 31, 2015Applicant: SIGNAL TRUST FOR WIRELESS INNOVATIONInventors: Marian Rudolf, Stephen E. Terry, Stephen G. Dick

Publication number: 20150372712Abstract: A wireless communications system employs code-division multiple access information transmission techniques where the uplink and downlink transmission bandwidths are unequal. The higher bandwidth is an integer multiple of the lower bandwidth. The present system requires a base station and a subscriber unit to have two pseudo-random code generators which can be clocked separately. Alignment of the uplink and downlink pseudo-random spreading codes is achieved by truncating the code sequence for the lower speed link at the conclusion of a complete code sequence for the higher speed link.Type: ApplicationFiled: September 1, 2015Publication date: December 24, 2015Applicant: SIGNAL TRUST FOR WIRELESS INNOVATIONInventor: Fatih M.

Patent number: 9215636Abstract: An enhanced uplink user equipment is in soft handover. A radio network controller selects a primary Node-B out of a plurality of Node-Bs supporting the soft handover. The radio network controller receiving successfully received enhanced uplink data packets from the plurality of Node-Bs. The radio network controller reordered the successfully received enhanced uplink data packets for in-sequence deliver. The primary Node-B sends specified scheduling information to the user equipment that the other Node-Bs does not transmit. At least the primary Node-B transmits acknowledgements and negative acknowledgements to the user equipment.Type: GrantFiled: June 3, 2013Date of Patent: December 15, 2015Assignee: Signal Trust for Wireless InnovationInventors: Guodong Zhang, Sung-Hyuk Shin, Stephen E.

Publication number: 20150333875Abstract: A method and apparatus for forwarding non-consecutive data blocks in enhanced uplink (EU) transmissions. A wireless transmit/receive unit (WTRU) and one or more Node-Bs include one or more automatic repeat request (ARQ)/hybrid-ARQ (H-ARQ) processes for supporting an enhanced dedicated channel (E-DCH). Data blocks transmitted by the WTRU are re-ordered in a re-ordering entity located in the Node-B(s) or a radio network controller (RNC). Once a missing data block is identified, a data forwarding timer in the Node-B(s) or RNC is initiated and subsequent WTRU transmissions are monitored to determine whether the missing data block has been discarded by the WTRU. Upon recognition of the discard of the missing data block, the non-consecutive data blocks are forwarded to higher layers.Type: ApplicationFiled: July 27, 2015Publication date: November 19, 2015Applicant: SIGNAL TRUST FOR WIRELESS INNOVATIONInventors: Guodong Zhang, Stephen E.

Publication number: 20150103666Abstract: 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: ApplicationFiled: December 19, 2014Publication date: April 16, 2015Applicant: SIGNAL TRUST FOR WIRELESS INNOVATIONInventors: Stephen E.
