Embodiment Construction

[0025] The techniques described herein provide mechanisms for providing discontinuous transmission in wireless networks. For example, a speech encoder in a base transceiver station or an access terminal encodes audio segments (typically 20 ms segments). The encoder provides an indication of whether each packet represents essential or non-essential audio. The modem receives the packet and the necessary / non-essential indication. To comply with one or more network standards (eg, maximum period without transmission), the modem sends every necessary packet and only those non-essential packets that the modem determines to send. Other embodiments are within the scope of the description and claims.

[0026] The techniques described herein may be used in various wireless communication systems such as CDMA, TDMA, FDMA, OFDMA, SC-FDMA, and others. The terms "system" and "network" are often used interchangeably. A CDMA system may implement a radio technology such as CDMA2000, Universa...

Abstract

A communication system for use in a wireless network, comprising: an audio module for providing an audio-indicative packet for use as part of a communication between said communication system and another communication system, the communication spanning a plurality of grouping periods, the grouping includes at least a necessary grouping indicating necessary audio; and a transceiver coupled to the audio module for: transmitting the necessary grouping for transmission; and transmitting a first non-essential grouping (indicating non-essential audio) for transmission such that (1) the first non-essential packet represents a period less than the total period between transmissions of the necessary packets, and (2) when one or the first of the necessary packets is not transmitted by the transceiver Where one of the non-essential packets is transmitted for transmission, no more than a threshold number of packet periods will elapse.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Application No. 61 / 119,318, filed December 2, 2008, entitled "Methods for Discontinuous Transmission," which is hereby incorporated by reference for all purposes. Background technique [0003] In order to provide various communication services such as voice, video, packet data, messaging, broadcast, etc., wireless communication systems are widely deployed. These wireless systems are multiple-access systems capable of supporting multiple users by sharing available system resources (eg, time, frequency, power). Examples of such multiple access systems include Code Division Multiple Access (CDMA) systems, Time Division Multiple Access (TDMA) systems, Frequency Division Multiple Access (FDMA) systems, Orthogonal FDMA (OFDMA) systems, and Single Carrier FDMA (SC-FDMA) systems. )system. [0004] A wireless communication system may include a number of base stations capable of...
