Abstract: Se describe en la presente proporcionar la asignación rápida de portadores (402) adicionales en sistemas de comunicación inalámbricos multiportadores. A modo de ejemplo, los protocolos de capa superior pueden emplearse para asignar portadores adicionales a los UE (304) en una red inalámbrica. Además, la gestión de portadores adicionales puede lograrse mediante los protocolos (206B) de señalización de capa inferior de alta velocidad. La gestión puede involucrar activar/desactivar los portadores adicionales, indicarle al UE que proporcione retroalimentación del portador, que monitoree los canales piloto o de control de tales portadores, o similares. Debido a que la señalización de capa inferior es relativamente rápida, la activación o desactivación del portador adicional puede implementarse rápidamente en respuesta a los cambios contemporáneos en las condiciones de canal. De esta manera, los cambios en la calidad de señal o carga de red pueden determinarse y utilizarse para personalizar la activación del portador en tiempo real próximo, proporcionar asignación eficiente de recursos mientras que se conserva la vida útil de la batería del UE.

Abstract: A method for wireless communications is provided. The method includes applying independent power controls to two or more carriers from a set of high speed packet access signals. The method includes monitoring power across the two or more carriers to determine power levels for the set of high speed packet access signals. The method also includes automatically adjusting at least one of the independent power controls in view of the determined power levels for the set of high speed packet access signals.

Abstract: Providing for fast allocation of additional carriers (402) in multi-carrier wireless' communication systems is de-scribed herein. By way of example, high layer protocols can be employed to allocate additional carriers to UEs (304) in a wire-less network. Additionally, management of the additional carriers can be accomplished via high, speed lower layer signaling proto-cols (206B). Management can involve acti-vating/deactivating the ' additional carriers, instructing the UE to provide carrier feed-back, monitor pilot or control channels of such carriers, or the like. Because lower layer signaling is relatively fast, activation or deactivation of the additional carrier can be quickly implemented in response to con-temporaneous changes in channel condi-tions. Thus, changes to signal quality or network loading can be determined and uti-lized to customize carrier activation in near real-time, providing efficient resource allo-cation' while conserving UE battery life.

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.

Abstract: Techniques for scheduling users for transmission on the uplink in a wireless communication system are described. A cell may perform interference cancellation for uplink transmissions and may observe lower effective noise and interference due to interference cancellation. The lower effective noise and interference may allow the cell to operate with a higher effective target load, which may support a higher overall throughput for the cell. In one design, an effective target load for a cell using interference cancellation may be determined, e.g., based on a target rise-over-thermal (RoT) for the cell and an interference cancellation efficiency factor. An available load for the cell may be determined based on the effective target load, which may be higher than a target load for the cell without interference cancellation. Users in the cell may then be scheduled for transmission on the uplink based on the available load.

Abstract: Systems and methods for bundling signals in a wireless communication syst em are disclosed. A connection request and a reservation for QoS resources c an be bundled into an access message at an access terminal. The access messa ge with the bundled communication signals can then be transmitted to an acce ss network. An application layer (e.g., a DataOverSignaling (DOS)) message c an also be bundled with the connection request and the reservation into the access message.

Abstract: Embodiments disclosed herein relate to methods and systems for providing adaptive server selection in wireless communications. An access terminal may be configured to determine a forward link quality metric associated with eac h 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 no n- serving sector at a DSC change boundary is greater than a predetermined threshold, where the non-serving sector and the serving sector for the acces s terminal belong to different cells. The access terminal may be further configured to change a data rate control (DRC) cover in accordance with the DSC change. The use of DSC may provide an early indication of handoff, there by allowing the service outage associated with server switching to be substantially reduced.

Abstract: métodos e aparelhos para aprimoramentos baseados em equipamento de usuário de controle de radiolink para transmissão sem fio multiponto. em aspectos da presente divulgação, um equipamento de usuário recebe transmissões multiponto inter-nó b, e um componente de agregação de multiponto detecta um intervalo nos números de sequência, retarda transmissão de um sinal de confirmação de negação (nak) iniciando um temporizador de retardo de nak, e transmite, por um transceptor, a nak para o intervalo em números de sequência em resposta ao temporizador de retardo de nak que expira e detecta que o intervalo não foi preenchido durante o retardo. se a entidade de controle de acesso ao meio (mac) como o respectivo nó b identifica-se com o controle de rádio link (rlc), de entrega fora de ordem (inclinação) pode, eventualmente, ser distinguida de perda de dados genuína antes do temporizador de retardo de nak expirar com base em rastreamento dos números de sequência maiores recebidos. temporizador de retardo de nak adaptativo pode ser realizado monitorando duração de inclinação.
