Abstract:
1. A method of data transmission in a cellular communication system including a base station used for mobile station data transmission over a downlink, in which the mobile station transmits base station data over an uplink, comprising the following steps: (a) M diversity groups of transmission channels each having K transmission channels, where M≧1, K≧1, are formed at the base station, (b) a pilot signal is transmitted from the base station to the mobile station from each of M·K transmission channels of diversity groups, (c) impulse responses of M·K transmission channels of diversity groups are estimated at the mobile station using the transmitted pilot signals, (d) L (e) for each of M diversity groups of transmission channels for each of L (f) a feedback signal containing L (g) L (h) channels of signal spectrum correction are formed at the base station for each of M diversity groups of transmission channels for each of L (i) information signal copies are formed at the base station for each of M diversity groups of transmission channels for each of L
