Abstract: A base station comprises a transmitter configured to transmit a downlink frame. The downlink frame comprising a first configuration message associated with the configuration of Enhanced-Multicast Broadcast Service (E-MBS). The first configuration message comprises a field with an indicator to indicate a next configuration message to be decoded by a subscriber station. The subscriber station, upon decoding the first configuration message, refrains from decoding subsequent configuration messages that precede the next configuration message to be decoded by the subscriber station in accordance with the indicator.

Abstract: A method constructs a family of low-density-parity-check (LDPC) codes. The method includes identifying a code rate for an LDPC code in the family, identifying a protograph for the LDPC code, and constructing a base matrix for the LDPC code. The base matrix is constructed by replacing each zero in the protograph with a ‘−1’, selecting a corresponding value for an absolute shift for each one in the protograph based on constraining a number of relative shifts per column of the LDPC code to one and increasing a size of a smallest cycle in a graph of the LDPC code, and replacing each one in the protograph with the corresponding value.

Abstract: A method from transmitting data via multiple antennas. In this method, four information bits to be transmitted are multiplexed by using either one of a code division multiplexing scheme or a second code division multiplexing scheme combined with a real and imaginary multiplexing scheme, to generate a code division multiplexed symbol including four vectors. Then, the code division multiplexed symbol is repeatedly transmitted by alternatively applying two transmit diversity schemes via four transmission antennas.

Abstract: 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.
