Abstract: A method for sending an uplink order to active set base stations is disclosed. A new mode of operation for a wireless communication device is determined. A transmission is sent on an uplink control channel to active set base stations that indicates the new mode. The transmission from the wireless communication device is received on the E-DPCCH. It is determined if the transmission is an uplink order. The new mode of operation is transitioned to. Subsequent transmissions from the wireless communication device are interpreted using the new mode of operation if the transmission is an uplink order.

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.

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.
