Abstract: An apparatus and a method are disclosed for jointly selecting precoding matrices for a plurality of received transmissions, such as those that might be received from a primary serving cell and a secondary serving cell in a multi-flow radio access network wherein each of the serving cells is configured to provide a MIMO transmission. Here, by jointly selecting the precoding matrices, interference from each of the downlink transmissions upon the other transmission can be reduced, thus improving overall performance at the receiving entity.

Abstract: Systems and methodologies are described that facilitate indicating channel resource usage information for receiving additional channel resources in a wireless network. An access point can initially receive a set of channel resources from a network controller for providing wireless network access to one or more devices. The access point can grant and/or deny requests for one or more of the channel resources from a plurality of devices and can feedback information to the network controller regarding the granting/denying. The network controller can determine a load on the access point based at least in part on the feedback information and adjust channel resource allocation based on the load. Thus, where an access point has granted close to capacity of allocated resources to one or more devices, the network controller can provide additional resources to the access point based on received feedback information related to the granted resources.

Abstract translation: 描述了便于指示用于在无线网络中接收附加信道资源的信道资源使用信息的系统和方法。 接入点可以最初从网络控制器接收一组信道资源，以提供对一个或多个设备的无线网络接入。 接入点可以授权和/或拒绝来自多个设备的一个或多个信道资源的请求，并且可以向网络控制器反馈关于授权/拒绝的信息。 网络控制器可以至少部分地基于反馈信息来确定接入点上的负载，并且基于负载调整信道资源分配。 因此，在接入点已经向一个或多个设备授予接近分配的资源的容量的地方，网络控制器可以基于接收到的与授权资源相关的反馈信息向接入点提供附加资源。

Abstract: A system and method enable wireless user equipment (UE) to undergo a serving radio network subsystem (SRNS) relocation to a radio network controller (RNC) that does not support a fast dormancy feature while maintaining synchronization with the packet-switched domain of the core network. The UE is made aware of whether the target RNC supports the fast dormancy feature by way of an indication provided to the UE in a reconfiguration message provided by the source RNC, that is, the RNC to which the UE was connected prior to the SRNS relocation. In this way, the UE can behave accordingly whether or not the target RNC supports the fast dormancy feature.

Abstract: The present disclosure provides methods and apparatuses for improved Iub link congestion management based on a dynamic scaling of flow control request message transmission in multiflow wireless environments. For example, in an aspect, methods and apparatuses are provided for receiving, at a NodeB, a data request from one or more user equipment (UE), wherein each data request corresponds to a flow and the one or more UE is served by a plurality of NodeBs, generating a flow control request corresponding to each flow in response to each data request, and sending each flow control request to a radio network controller (RNC). Thereafter, a Node B may receive data in response to each flow control request, determine a congestion state based on a downlink delay from the RNC detected in the received data, and scale a subsequent one or more flow control requests based on the determined congestion state.

Abstract: A method and apparatus for wireless communication may provide a multi-link PDCP sublayer in a radio network controller capable of allocating PDCP PDUs among a plurality of RLC entities for use in a multi-point HSDPA network. Some aspects of the disclosure address issues relating to out-of-order delivery of the PDCP PDUs to a UE, such as unnecessary retransmissions. That is, the disclosed multi-link PDCP may be capable of distinguishing between sequence number gaps that are caused by physical layer transmission failures and those caused merely by skew.

Abstract: A method of communicating speech comprising time-warping a residual low band speech signal to an expanded or compressed version of the residual low band speech signal, time-warping a high band speech signal to an expanded or compressed version of the high band speech signal, and merging the time-warped low band and high band speech signals to give an entire time-warped speech signal. In the low band, the residual low band speech signal is synthesized after time-warping of the residual low band signal while in the high band, an unwarped high band signal is synthesized before time-warping of the high band speech signal. The method may further comprise classifying speech segments and encoding the speech segments. The encoding of the speech segments may be one of code-excited linear prediction, noise-excited linear prediction or ⅛ frame (silence) coding.
