Patent number: 9167489Abstract: A variety of wireless communication methods and apparatus for supporting reconfiguration of radio link control (RLC) parameters are disclosed. A radio resource control (RRC) reconfiguration message is generated that indicates that an RLC unit in a wireless transmit/receive unit (WTRU) or a universal terrestrial radio access network (UTRAN) should be reconfigured from supporting flexible size RLC protocol data units (PDUs) to supporting fixed size RLC PDUs. If an information element (IE) “one sided RLC re-establishment” is present in the RRC reconfiguration message, only a receiving side subassembly in the RLC unit is re-established. Otherwise, both the receiving side subassembly and a transmitting side subassembly in the RLC unit are re-established. Flexible size RLC PDUs may be discarded and a message indicating the discarded flexible size RLC PDUs may be transmitted. The flexible size RLC PDUs may be modified such that they correspond to a set of pre-defined sizes.Type: GrantFiled: March 4, 2014Date of Patent: October 20, 2015Assignee: InterDigital Technology CorporationInventors: Stephen E.

Patent number: 9118605Abstract: Multiple RSVP messages are used to separately signal components of co-routed VCAT to enable the separate components to be implemented on different physical fibers of a link bundle. To enable the PATH messages to be handled as a group, the multiple PATH messages are grouped together and sent out in a RSVP bundle message. When a RSVP bundle message containing multiple PATH messages is received at a network element, such as an ENNI, where the route for the PATH messages needs to be expanded, the route is expanded collectively and the expanded route is inserted into each individual PATH message. The modified PATH messages are then passed through the RSVP finite state machine one at a time to enable resources to be reserved for the connections of the VCAT. Thus, a single LSP may be created for each channel, and channels may be co-routed even where route expansion is required.Type: GrantFiled: November 19, 2013Date of Patent: August 25, 2015Assignee: RPX CLEARINGHOUSE LLCInventors: Darek Skalecki, Evelyne Roch

Patent number: 9112692Abstract: Techniques for acknowledging data transmissions in a multi-carrier wireless communication network are disclosed. In some aspects, a user equipment (UE) receives a data transmission on at least one component carrier (CC) in a plurality of configured CCs. The UE determines acknowledgement/negative acknowledgement (ACK/NACK) information for the data transmission and determines an uplink channel for sending the ACK/NACK information. When the ACK/NACK information is sent on a physical uplink control channel (PUCCH), the UE may perform power control based on which CCs in the plurality of configured CCs data is received. When the ACK/NACK information is sent on a physical uplink shared channel (PUSCH), the UE may determine a number of resource elements based on its CC configuration.Type: GrantFiled: August 13, 2011Date of Patent: August 18, 2015Assignee: QUALCOMM IncorporatedInventors: Wanshi Chen, Xiaoxia Zhang, Peter Gaal, Juan Montojo, Xiliang Luo, Tao Luo, Jelena M.
