Transmitting data to receiver device involves transmitting at least one individual pilot sequence via transmission signals over radio interface for channel estimation using CAZAC codes

摘要

The method involves transmitting at least one individual pilot sequence (t1,t2) via the transmission signals over the radio interface (V) for channel estimation and using CAZAC codes (c1,c9) for the pilot sequences. Each transmitted signal is transmitted via a transmission antenna associated with the signal of a transmitter (MT1) with several transmission antennas. An independent claim is also included for the following: (a) a communications arrangement for transmitting data via at least two transmission signals over radio interface of communications system involves .
