Publication number: 20160014720Abstract: A method and apparatus are described for providing multimedia broadcast multicast services (MBMS) service feedback. A wireless transmit/receive unit (WTRU) may receive an MBMS service query message over an MBMS control channel and transmit an MBMS service response. The MBMS service query message and MBMS service response message may be radio resource controller messages. The MBMS service query message may include MBMS service identifiers which identify MBMS services that the WTRU is receiving or intending to receive. The WTRU may generate a report with MBMS service identifier index values, where each MBMS service identifier index value indicates a position of a service identifier corresponding to an MBMS service in the original query list that the WTRU is currently receiving or intending to receive. The MBMS service status query message may be received alone or along with a MBSFNAreaConfiguration message. The WTRU may respond within a predetermined or configured time limit.Type: ApplicationFiled: July 13, 2015Publication date: January 14, 2016Applicant: INTERDIGITAL PATENT HOLDINGS, INC.Inventors: Peter S.

Publication number: 20150327255Abstract: Embodiments contemplate enabling relay node uplink control information transmission on an interface between a relay node and a donor eNodeB (DeNB) in one or more subframes. Embodiments contemplate techniques to avoid restrictions on uplink transmissions on a cell (perhaps due to subframe configuration), such as on a primary cell, where the restrictions may make relay node uplink control information transmission difficult (if not impossible) on the interface between a relay node and a donor eNodeB (DeNB). Embodiments also contemplate that resources on the interface between the relay node and the donor eNodeB may be scheduled across one or more component carriers or serving cells.Type: ApplicationFiled: July 21, 2015Publication date: November 12, 2015Applicant: INTERDIGITAL PATENT HOLDINGS, INC.Inventors: Nobuyuki Tamaki, Ghyslain Pelletier, Janet A.

Patent number: 9088926Abstract: A method for performing radio usage measurements to support radio link operations and/or load balancing may be performed at an evolved Node B (eNB). The method may include determining a first radio usage parameter. The first radio usage parameter may be a measurement of radio usage between an eNB and at least one wireless transmit receive unit (WTRU). The method may further include determining a second radio usage parameter. The second radio usage parameter may be a measurement of radio usage between the eNB and at least one relay node (RN) served by the eNB. The method may further include utilizing at least one of the first radio usage parameter or the second radio usage parameter to evaluate at least one of evolved universal terrestrial radio access (E-UTRA) radio link operations, radio resource management (RRM), network operations and maintenance (OAM), and self-organizing networks (SON) functions or functionalities.Type: GrantFiled: May 17, 2013Date of Patent: July 21, 2015Assignee: INTERDIGITAL PATENT HOLDINGS, INC.Inventors: Kai Liu, Peter S.
