    摘要: A system and method for employing six-bit rank 1 and 2 codebooks for four transmit antennas is provided. A method for communications device operation includes estimating a communications channel between the communications device and a controller serving the communications device, thereby producing a channel estimate, quantizing the channel estimate using a codebook, thereby producing a selected codeword, and transmitting an index corresponding to the selected codeword from the codebook to the controller. The codebook includes a plurality of first level codewords, with each first level codeword having a plurality of subsidiary codewords. The quantizing is a search of only the first level codewords followed by a search of a subset of the plurality of subsidiary codewords, and the codebook is based on a rank of communications between the communications device and the controller.

    摘要: Apparatus, and an associated method, for facilitating operation of a radio communication system that provides for multi rate data communications, such as a CDMA 2000 system that provides for 1xEV-DV communication services. A supplemental pilot, or control, signal generator embodied at a mobile station generates a supplemental pilot, or control, signal that is sent on a newly defined supplemental pilot, or control, channel. As the data rates of data communicated upon a reverse supplemental channel changes, corresponding changes are made to the power level of the reverse supplemental pilot, or control, signal.

    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.

    摘要: Adaptive precoding codebooks are described. In one embodiment, the method of wireless communication includes reading at least a rank-2 baseline codebook having codewords representing precoding matrices. An adaptive codebook is generated by multiplying a first column of the codeword with a first transform matrix calculated from a channel correlation matrix, and multiplying a second column of the codeword with a second transform matrix calculated from the channel correlation matrix. The first and the second transform matrices are orthogonal.
