  • Patent number: 8477734
    Abstract: Techniques for reporting acknowledgement (ACK) information and channel quality indication (CQI) information in a wireless communication system are described. A user equipment (UE) may be able to receive data from up to two cells with dual-cell operation. The UE may determine CQI information for a first cell, determine CQI information for a second cell, and send the CQI information for both cells on a feedback channel with a single channelization code. The UE may process a control channel from each cell and, if control information is received from the cell, may further process a data channel from the cell to receive data sent to the UE. The UE may determine ACK information for each cell based on processing results for the data and control channels from that cell. The UE may send the ACK information for both cells on the feedback channel with the single channelization code.

  • Patent number: 8340698
    Abstract: A method for delivering SMS to ATs in a first communication network providing DO and 1x interfaces and for offloading the delivery of the SMS from a second communication network including an MSC, comprising monitoring a DO control channel for pages by an AT and delivering the SMS in SIP to the AT over the DO interface. The method may further comprise tuning the AT to the DO interface and determining whether the AT is SIP registered for using the DO interface. An application server determines whether the AT is SIP registered for using the DO interface. When the DO interface is not available, the SMS may be delivered over the 1x interface and the method further comprises the AT sending a special SMS to an SMS gateway, which causes the application server to remember that the AT is now monitoring the first communication network including a circuit-switched network.

  • Patent number: 8184599
    Abstract: Techniques for managing operation of a user equipment (UE) in a multi-carrier system are described. The system may support two or more carriers on the downlink and one or more carriers on the uplink. One carrier on each link may be designated as an anchor carrier. In an aspect, a lower layer order (e.g., an HS-SCCH order) may be used to transition the UE between single-carrier and multi-carrier operation. In another aspect, the UE may have the same discontinuous reception (DRX) configuration for all downlink carriers and/or the same discontinuous transmission (DTX) configuration for all uplink carriers. In yet another aspect, HS-SCCH-less operation may be restricted to the anchor carrier.

  • Patent number: 8121128
    Abstract: Techniques for controlling transmission of packets on multiple links are described. In one design, a transmitter may generate packets of data for a receiver, assign the packets with sequence numbers from a single sequence number space, demultiplex the packets into multiple streams for multiple links, and send each stream of packets on the associated link to the receiver. The receiver may receive some packets in error, and the correctly received packets may be out of order. In one design, the receiver may maintain the largest sequence number of correctly received packets for each link. After detecting at least one missing packet, the receiver may send status information conveying the missing packet(s) and the largest sequence numbers for all links to the transmitter. The transmitter may use the largest sequence numbers for all links and its packet-to-link mapping to determine whether to quickly resend each missing packet or wait.

  • Publication number: 20110019625
    Abstract: Techniques for scheduling data transmission on multiple carriers in a wireless communication system are described. In one design, a scheduler may receive requested power headrooms for multiple carriers from a user equipment (UE), one requested power headroom for each carrier. Each requested power headroom may be indicative of transmit power usable by the UE for transmission on an associated carrier. The scheduler may also receive queue information indicative of data to transmit by the UE. The scheduler may redistribute the requested power headrooms across the multiple carriers (e.g., based on water filling or greedy filling) to obtain redistributed power headrooms for the multiple carriers. The scheduler may schedule the UE for data transmission on the uplink based on the redistributed power headrooms and the queue information. The scheduler may obtain and send at least one granted power headroom for at least one carrier to the UE.

  • Patent number: 7870231
    Abstract: A wireless data network delivers packets from a network router to a mobile station so that each application running on the mobile station receives an adequate quality of service (QoS). The mobile station sends configuration messages to the network router containing prioritized filters associated with each application. The router filters incoming IP packets into IP flows having the appropriate QoS for the corresponding application. The configuration messages consume valuable air interface resources. Network resources are conserved by assigning precedence values to filters in such a way that fewer configuration messages are needed to reorder the filters when new filters are added. Precedence values for existing filters are spread out in one portion of the precedence space. When the precedence values in that portion are insufficient to accommodate new filters with the correct priority, both new and existing filters are reassigned precedence values in an unassigned portion of the precedence space.

  • Publication number: 20100238857
    Abstract: Synchronization of uplink carriers for transmission is disclosed in accordance with different aspects. The uplink carriers that transmit information are configured such that at least one of the uplink carriers is an anchor carrier. When a plurality of carriers are thus configured for the uplink, they are synchronized such that they bear a predetermined phase relationship with each other. The predetermined phase relationship between the plurality of carriers depends on the transmit timing of the anchor carrier or a combination of transmit timings of the anchor carrier and one or more non-anchor carriers comprised within the uplink carriers.
