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.

Abstract: In a wireless communication system in which a user using a mobile equipment requests a serving cell handoff from a source cell to a target cell, the mobile equipment monitors authorization for the handoff from the target cell. At the same time, the mobile equipment can decode data from either the source cell or the target cell. Upon receipt of authorization for the handoff, the mobile equipment sends confirmation of the handoff to the target cell.

Abstract: A system and method for optimizing robust header compression between a compressor (residing at AN/AT) and a decompressor (residing at AT/AN), the method comprising initializing the compressor with an estimated jitter value before the compressor; notifying the decompressor of the estimated jitter value before the compressor; estimating various threshold limits at the decompressor based on the sum of the jitter between the compressor and the decompressor (JITTER_CD) and that before the compressor (JITTER_BC); the decompressor sending a JITTER option whenever the threshold limits are exceeded; and the compressor adjusting a packet size in response the received JITTER option. The estimated jitter value before the compressor may be based on simulations or channel characteristics. Notification to the decompressor of the jitter value before the compressor may be achieved by signaling or hard-coding a same value at the compressor and the decompressor.
