Abstract: A method in a wireless terminal transceiver includes receiving a sequence of frames from a first base station, wherein each frame in the sequence contains a first set of time-frequency resources which may be used for scheduling data and a second set of time-frequency resources not used for scheduling data. The transceiver also receives a message from the first base station identifying a third set of time-frequency resources that is a subset of the first set of time-frequency resources, and estimates the channel state based on the transmission received in the third set of time-frequency resources.

Abstract: The present invention provides a broadcast channel signal and apparatus for managing the transmission and receipt of broadcast channel information, where a known difference in the data prior to encoding for transmission produces a predictable difference, which can be removed or cancelled from the multiple received active frames, such that their differences can be negated prior to combining and subsequently decoding. In at least one embodiment one or more applied linear encoding techniques can allow for a predictable difference in the encoded values based upon a knowledge of the difference prior to encoding.

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).
