Patent number: 9622178Abstract: A method and a user equipment (UE) are described for controlling timers in a wireless communication system including a first type network communicating based on a number of orthogonal frequency-division multiplexing (OFDM) symbols and a second type network which is different from the first type network. An update message is received that activates an idle mode signaling reduction (ISR) function of the UE. If the ISR function is activated in the UE, a periodic tracking area updating (P-TAU) timer is started, which is used to periodically notify availability of the UE. If the P-TAU timer expires and a mobility management backoff (MM-BO) timer is running, a deactivate ISR timer corresponding to the first type of network is started. The MM-BO timer is configured to start when a MM-BO time value is received at the UE.Type: GrantFiled: June 30, 2015Date of Patent: April 11, 2017Assignee: LG ELECTRONICS INC.Inventor: Li-Hsiang Sun

Patent number: 9548802Abstract: A wireless transmit/receive unit (WTRU) receives a downlink transmission from an eNodeB including a plurality of spatial layers transmitted to a plurality of WTRUs paired for multi-user MIMO. The WTRU decodes the downlink transmission based on a corresponding WTRU-specific reference signal. WTRU-specific reference signals are multiplexed using a frequency and code division multiplexing. WTRU-specific reference signals for different sub-group of antenna ports are multiplexed onto different subcarriers in a frequency domain and the WTRU-specific reference signals of the same sub-group of antennas ports are multiplied by an orthogonal cover code. The resource elements used for the WTRU-specific reference signals on antenna ports in one sub-group may be muted on antenna ports in another sub-group. A WTRU may transmit the uplink demodulation reference signal without precoding.Type: GrantFiled: August 10, 2012Date of Patent: January 17, 2017Assignee: InterDigital Patent Holdings, Inc.Inventors: Shahrokh Nayeb Nazar, Moon-il Lee, Robert L.

Patent number: 9516651Abstract: Techniques are disclosed for identifying carrier-aggregation band combinations that may be supported by a mobile terminal with limited performance. According to one example method, a mobile terminal sends (710) a band capability information element to the network (e.g., to a 3GPP eNB). The band capability information element contains data indicating which band combinations the mobile terminal supports for carrier aggregation. In addition, the mobile terminal sends (720) additional information (e.g., one or more new parameters) associated with at least one specific band combination. In some cases, this new information indicates that a specific band combination has limited support. In these or in other embodiments, the new information contains information about an amount or type of limitation. This latter information may be present on its own, or in combination with the information that more generally indicates that the mobile terminal is capable of only limited support for a specific band combination.Type: GrantFiled: March 21, 2013Date of Patent: December 6, 2016Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Lisa Boström, Magnus Larsson, Christian Skärby

Patent number: 9515756Abstract: Methods, devices, and computer program products facilitate establishing timing synchronization between two network entities. The timing information is exchanged between a slave device and a master device at the discretion of the slave device. The exchange of timing information can, therefore, be conducted adaptively based on the needs of the salve device. The timing information is also exchanged using fewer messages, thereby reducing network traffic, reducing overhead and facilitating synchronization acquisition.Type: GrantFiled: November 22, 2011Date of Patent: December 6, 2016Assignee: SpiderCloud Wireless, Inc.Inventors: Peter G.

Patent number: 9509547Abstract: The invention includes methods of using IMS Centralized Services, ICS, in the selection of a service domain relating to a call involving a User Equipment, UE, being served by a CS access network. In one aspect a method includes receiving a request from a routing node, such as a Mobile Switching Center, MSC, or a Gateway Mobile Switching Center, GMSC, for a service domain selection at a Service Control Point, SCPin the UE's IMS network (801). The SCP has a Service Domain Selection, SDS, function, which retrieves data relating to the UE from a Domain Selection function (802). Based on the retrieved data, the SDS selects either the IMS service domain or the CS service domain as the service domain for routing the call (803), and sends an indication of the selected service domain to the routing node (805). Other aspects include methods for domain selection at the originating and terminating sides of the call, and network entities configured to carry out the methods.Type: GrantFiled: December 7, 2010Date of Patent: November 29, 2016Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Ralf Keller, Fredrik Lindholm

Patent number: 9455948Abstract: In one embodiment, the processing by a packet switching device of a received network-to-link-layer address resolution request message (e.g., Address Resolution Protocol [ARP] Request message, Neighbor Discovery Protocol [NDP] Neighbor Solicitation message) is dependent upon whether or not its target IP address corresponds to a network gateway packet switching device. When the target IP address of a received ARP Request/NDP Neighbor Solicitation message corresponds to a network gateway, then the packet switching device responds effectively on behalf of the network gateway, rather than forwarding the message to the network gateway. When the target IP address of a received ARP Request/NDP Neighbor Solicitation message does not correspond to a network gateway and the Media Access Control (MAC) address corresponding to the target IP address is known, then the packet switching device transforms then sends the broadcast or multicast frame into a unicast frame.Type: GrantFiled: August 10, 2012Date of Patent: September 27, 2016Assignee: Cisco Technology, Inc.Inventors: Ramkumar Sankar, Varagur Chandrasekaran, Murali Basavaiah
