    Abstract: Se proporcionan sistemas y metodologías que facilitan el equilibrio de carga dinámica en una red de comunicaciones; en particular, uno o más dispositivos móviles pueden enviar preámbulos de acceso aleatorio en una frecuencia de enlace ascendente en par con una frecuencia de enlace descendente empleada para conectar uno o más dispositivos móviles a una estación base; la estación base puede determinar si existe un desequilibrio de carga de frecuencia de enlace ascendente con base en los preámbulos de acceso aleatorio; la estación base puede transmitir un indicador sobre un canal indicador de adquisición al menos a un dispositivo móvil, en donde el indicador incluye un comando para cambiar a una nueva frecuencia de enlace ascendente; el dispositivo móvil puede conmutar frecuencias de enlace ascendente en respuesta al comando.

    Abstract: Embodiments disclosed herein relate to methods and systems for providing adaptive server selection in wireless communications. In an embodiment, an access terminal is configured to determine a forward link quality metric associated with each of a plurality of sectors serviced by a plurality of access points; assign credits to each sector in relation to the forward link quality metric; and change a data source control (DSC) value if the credits accumulated for a non-serving sector at a DSC change boundary is greater than a predetermined threshold, where the non-serving sector and the serving sector for the AT belong to different cells. The access terminal is further configured to change a data rate control (DRC) cover in accordance with the DSC change. The use of DSC provides an early indication of handoff, thereby allowing the service outage associated with server switching to be substantially reduced. A method for handoff is further disclosed using DSC as early indication of handoff, which also trigger multitasking forward traffic for the access terminal to all access points.

    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.

    Abstract: Methods and apparatuses for facilitating managing cells in a multi-carrier system from an access terminal and base station are provided. The base station and access terminal communicate via an anchor carrier and a supplementary carrier. A triggering algorithm generated by the base station is transmitted to the access terminal. The triggering algorithm includes instructions for the access terminal to report downlink measurements as a function of trigger events detected over the anchor carrier and/or the supplementary carrier. Downlink measurements taken by the access terminal are provided to the base station. Cell management instructions based in part on the downlink measurements are then provided to the access terminal by the base station.

    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 os 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.

    Abstract: A method, an apparatus, and a computer program product for wireless communication are provided in which a plurality of uplink carriers are utilized in a cellular communications system. In an aspect of the disclosure, a wireless terminal configured for use in a cellular network transmits an uplink with a plurality of uplink carriers including an anchor carrier and a secondary carrier, and receives a downlink with a plurality of downlink carriers. Here, the wireless terminal provides feedback information, such as a channel quality indicator and an acknowledgment, corresponding to the plurality of downlink carriers, on an uplink channel on each of respective carriers in a subset of the plurality of uplink carriers.
