Data transmission in radio communications system with transmission diversity involves transmitting subscriber data signal via at least two antenna devices, reference signal via only one antenna device

摘要

The data transmission method involves associating a subscriber data signal (TN1) and a reference signal with a subscriber, transmitting the subscriber data signal at the transmitter end via at least two antenna devices (ANT1,2) and transmitting the reference signal (REF) at the transmitter end via only one antenna device. The reference signal is transmitted periodically or aperiodically at randomly selected time intervals.
