摘要： A data transmission method and system for circuit switched and other services that can be employed in TDMA-based systems, and that supports the use of one or several types of modulation (e.g., 8-PSK modulation), in addition to a “normal” modulation (e.g., GMSK modulation) on a radio interface. An additional modulation/channel coding (e.g., one based on 8-PSK) may be used in the downlink transmission, while the normal modulation/channel coding (e.g., one based on GMSK) may be used in the uplink transmissions, under a variety of different conditions. A first condition arises where the radio conditions allow the use of the additional modulation in both directions, but the mobile station transmitter does not support it. A second condition arises where the radio conditions allow the use of the additional modulation in both directions, and the mobile station supports it, but the user requests a downlink-biased or uplink-biased data transmission service. A third condition arises where the mobile station supports the use of the additional modulation in both directions, but the uplink (or downlink) radio conditions do not permit the use of the additional modulation (e.g., because of link budget limitations.) Also, a lower data rate may be desired on the uplink in order to reduce the power consumption of the mobile station, and/or in the downlink direction to avoid unnecessary interference. This is especially true in the case that one direction or the other has less data to transmit, and the high speed data transmission mode is not required (even if supported).

摘要： A method is presented for demodulating and decoding a block of received digital information consisting of a number of subblocks. One of a predefined number of demodulation methods is selected for demodulating each subblock and each subblock is demodulated with the demodulation method selected for it. The subblocks constituting a block of digital information are combined between their demodulation and the decoding of the block of digital information. Soft decoding is used to decode the block of digital information, wherein each subblock is converted to a sequence of soft decoding values associated with certain probabilities of allowed state transitions in the decoding process. For each subblock it is determined, after its demodulation, whether the correct demodulation method was selected for it. A subblock for which it is found that the correct demodulation method was not selected is converted to a sequence of neutral soft decoding values indicating equal probabilities for all allowed state transitions in the decoding process.
