Patent number: 10492154Abstract: 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.Type: GrantFiled: May 22, 2017Date of Patent: November 26, 2019Assignee: InterDigital Technology CorporationInventors: Stephen G.

Patent number: 10390279Abstract: A method and system for an enhanced uplink (EU) operation in a wireless communication system during soft handover. The system comprises a wireless transmit/receive unit (WTRU), at least two Node-Bs, and a radio network controller (RNC). One Node-B may be designated as a primary Node-B, and the primary Node-B may control EU operation during soft handover including uplink scheduling and hybrid automatic repeat request (H-ARQ). Soft buffer corruption is avoided during soft handover by controlling H-ARQ by the primary Node-B. Alternatively, an RNC may control EU operation during soft handover including H-ARQ. In this case, an RNC generates final acknowledge/non-acknowledge (ACK/NACK) decision based on the error check results of the Node-Bs.Type: GrantFiled: July 18, 2016Date of Patent: August 20, 2019Assignee: Signal Trust for Wireless InnovationInventors: Stephen G.
