    摘要: Various embodiments are disclosed relating to techniques to transmit data rate control signals for multicarrier wireless systems. According to an example embodiment, a wireless apparatus may be adapted to transmit at least a first data rate control (DRC) value via an in-phase channel and at least a second DRC value via a Quadrature-phase channel. The first DRC value may be associated with a first forward link carrier and the second DRC value may be associated with a second forward link carrier. In this manner, DRC values may be transmitted over both the I and Q channels, for example.

    摘要: An approach is provided for addressing in a multiple carrier communication system. In one embodiment, a group index is assigned to a group of terminals of a communication network. The group index permits sharing of addressing indices supported by the communication network for transmission of data to the group of terminals. In another embodiment, a plurality of terminals is classified using preamble indices corresponding to the terminals into one or more classes. A multi-user packet, which utilizes the preamble indices to activate only a class of the terminals for processing the multi-user packet, is generated.

    摘要: Various techniques are disclosed to improve redundancy in multi-carrier wireless systems. An example technique is provided that may include commonly encoding a block of data, modulating the encoded block of data across a plurality of carriers, and transmitting via a wireless link the encoded block of data including the plurality of carriers. The modulating may, for example, include modulating a first portion of the encoded block onto a first carrier and modulating a second portion of the encoded block onto a second carrier, wherein encoded data on the first carrier for the block of data may be used for error detection and/or error correction of encoded data on the second carrier for the block of data. Error detection and correction for the encoded block may be performed across the plurality of carriers, which may provide frequency diversity for the block of data.

    摘要: The present invention concerns methods for efficiently supporting Voice over Internet Protocol (VoIP) on the Forward Packet Data Channel (F-PDCH) in CDMA 2000 1xEV-DV systems. Active speech in VoIP is encoded using, for example enhanced variable rate codec (EVRC), which produces 171, 80 and 16 bits per 20 ms of speech for Rate 1, Rate ½ and Rate ⅛, respectively. However, about 60% of the time a user is inactive during a speech session, so an inordinate amount of system bandwidth is comprised of rate ⅛ VoIP packets. In one embodiment of the present invention the apparatus of the present invention identifies the Rate ⅛ voice frame packets and discards them. In another embodiment of the present invention, the apparatus of the present invention identifies the Rate ⅛ voice frame packets and selects some of them for further transmission. In both embodiments the efficiency of channel utilization is increased since the amount of channel band width used to communicate relatively little information, e.g., gaps of silence, is decreased.
