摘要： A method and apparatus are provided for combining pilot symbols and Transmit Parameter Signalling (TPS) channels within an OFDM frame. The method uses Differential Space-Time Block Coding to encode a fast signalling message at an OFDM transmitter. At an OFDM receiver, the encoded fast signalling message can be decoded using differential feedback to recover information about the channel responses that would normally be carried by pilot symbols. In wireless data transmission employing adaptive modulation and coding, an instantaneous channel quality measurement, independent of the origin of interference for example, neighboring-cell interference, white thermal noise, or residual Doppler shift is provided. Using the correlation between a signal which has been symbol de-mapped, and one which has also been soft decoded and re-encoded, a channel quality indicator is produced. Another embodiment uses TPS data as pilot symbols by decoding TPS and then re-encoding.

摘要： A method and apparatus are provided for performing acquisition, synchronization and cell selection within an MIMO-OFDM communication system. A coarse synchronization is performed to determine a searching window. A fine synchronization is then performed by measuring correlations between subsets of signal samples, whose first signal sample lies within the searching window, and known values. The correlations are performed in the frequency domain of the received signal. In a multiple-output OFDM system, each antenna of the OFDM transmitter has a unique known value. The known value is transmitted as pairs of consecutive pilot symbols, each pair of pilot symbols being transmitted at the same subset of sub-carrier frequencies within the OFDM frame.

摘要： The present invention provides a technique for supporting variable bitrate services in an OFDM environment while minimizing the impact of the variations of fading channels and interference. In general, a basic access channel (BACH) is defined by a set number of sub-carriers over multiple OFDM symbols. While the number of sub-carriers remains fixed for the BACH, the sub-carriers for any given BACH will hop from one symbol to another. Thus, the BACH is defined by a hopping pattern for a select number of sub-carriers over a sequence of symbols.

摘要： The present invention provides a technique for scheduling data, and in particular, scheduling real-time or voice data for transmissions during a transmit time interval in a multi-carrier communication environment. For each transmit time interval, channel condition indicia for multiple users is determined, and an iterative scheduling process is then implemented based in part on the channel condition indicia. The iterative scheduling initially preassigns select tones for each of the remaining users that have not been permanently assigned tones for the given transmit time interval. Next, the remaining user having the least favorable channel conditions is selected as an active user. The newly selected active user is then permanently assigned the select tones that were initially pre-assigned to that particular user. The permanently assigned tones are removed from consideration, and the process is repeated until all the remaining users are permanently assigned unique tones for scheduling.

摘要： The present invention relates to space-time coding techniques capable of providing incremental redundancy in wireless communication environments incorporating spatial and temporal diversity. In general, a transmitter sends packets, via blocks of symbols, to a receiver with high bandwidth efficiency and only in the event that the receiver does not correctly receive a data packet does the transmitter send additional symbols to assist with the decoding of the incorrectly received packet. A hybrid ARQ feedback mechanism is used such that the receiver can inform the transmitter whether the packets were correctly or incorrectly received. From the feedback, the transmitter can determine whether to send new symbols or initiate incremental redundancy. By combining the received words corresponding to the redundant symbols and those of the original packet transmission, additional diversity, coding gain, signal energy, or a combination thereof are provided to the receiver and are used to correctly decode the transmitted data.
