Patent number: 9603099Abstract: A method and apparatus for determining uplink power in a wireless transmit receive unit (WTRU). The WTRU operates in a carrier aggregated system. The WTRU is configured to receive a plurality of uplink power parameters indexed to one of a plurality of uplink carriers and receive a transmit power control command indexed to the one of the plurality of uplink carriers. The WTRU is configured to determine a pathloss of the one of the plurality of uplink carriers and determine a transmit power for the one of the plurality of uplink carriers based on the plurality of power parameters, the transmit power control command, and the pathloss.Type: GrantFiled: March 16, 2015Date of Patent: March 21, 2017Assignee: InterDigital Patent Holdings, Inc.Inventors: Sung-Hyuk Shin, Guodong Zhang, Janet A. Stern-Berkowitz, Philip J. Pietraski, Stephen G. Dick, Joseph S. Levy, Kyle Jung-Lin Pan, Erdem Bala, Marian Rudolf, Stephen E. Terry, Changsoo Koo, Charles A. Dennean, Eldad M. Zeira

Publication number: 20170013612Abstract: Methods and systems for transmitting uplink control information and feed back are disclosed for carrier aggregation systems. A user equipment device may be configured to transmit uplink control information and other feedback for several downlink component carriers using one or more uplink component carriers. The user equipment device may be configured to transmit such data using a physical uplink control channel rather than a physical uplink shared channel. The user equipment device may be configured to determine the uplink control information and feedback data that is to be transmitted, the physical uplink control channel resources to be used to transmit the uplink control information and feedback data, and how the uplink control information and feedback data may be transmitted over the physical uplink control channel.Type: ApplicationFiled: September 19, 2016Publication date: January 12, 2017Applicant: INTERDIGITAL PATENT HOLDINGS, INC.Inventors: Shahrokh Nayeb Nazar, Kyle Jung-Lin Pan, Robert L. Olesen, Ghyslain Pelletier, Marian Rudolf, Paul Marinier, Charles A. Dennean, Stephen G. Dick, Allan Y. Tsai, Christopher R. Cave, Changsoo Koo
