Abstract: 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.

Abstract: A method and apparatus for communications channel symbol recovery that improves equalizer performance adds together the log-likelihood ratios (LLRs) of different decision delays rather than using LLRs corresponding only to a single decision delay. A low complexity method comprises, determining an initial coarse delay and a set of fine delays (1003), estimating a training sequence and filter taps set for each fine delay (1007), determining an error function for each fine delay (1009), and linearly combining the filter taps (1013) for determining the symbol estimates (1017).
