摘要： A base station (103) assigns a set of mobile stations (101) to a group wherein the group will share a set of radio resources (770). A control field (1103) may be sent with a payload field (1105) wherein the control field (1103) and payload field (1105) are sent using a single Orthogonal Variable Spreading Factor or a single Walsh Code (1101) wherein various modulation and coding schemes may be applied to the control field (1103) and payload field (1105) such that different modulation and coding schemes may be used within the single channel. HARQ is handled by sending a single retransmission if a NACK message is received or no ACK/NACK message is received at all.

The number of candidate sequences may be reduced using computational complexity reduction methods. A communications device also provides a candidate sequence generator for use with a CRC decoder to determine a most-likely received sequence and to reduce bit errors in a received sequence.

摘要： An improved turbo code based incremental redundancy includes a first step of puncturing a data stream for a first transmission to provide a set of first unpunctured trellis sections. A next step includes puncturing a data stream for a second transmission to provide a set of second unpunctured trellis sections. A next step includes incremental redundancy combining the first and second transmissions of the trellises to provide non-adjacent first and second unpunctured trellis sections. The above arrangement results in a uniform distribution of punctured and unpunctured bits to provide lower errors.

摘要： The present invention provides a method for transmitting broadcast channel information as part of a broadcast channel signal having one or more transmission intervals, where each transmission interval includes a plurality of transmissions, and one or more of the transmissions are active frames in which broadcast channel information is transmitted. Invariant portions that are present in the broadcast channel information are identified separate from any variant portions and are encoded for transmission, and the variant portions are used to select transmission specific configurations, which can be detected during the decoding by the receiver. Upon detection of the transmission specific configuration used to encode the invariant portions, the value of the variant portion can be identified and reintroduced as part of the received broadcast channel information.
