移動通信システムにおける信号送信方法

Title:

移動通信システムにおける信号送信方法

Document Type and Number:

Japanese Patent JP4351246

Kind Code:

B2

Abstract:

A method of transmitting a signal in a mobile communication system using multiple antennas including allocating bit-mapped symbols to the multiple antennas based on a correlation among the multiple antennas. Further, allocating the bit-mapped symbols allocates bit-mapped symbols transmitted from antennas having a higher correlation among each other to be retransmitted from antennas having a lower correlation among each other, and allocates bit-mapped symbols transmitted from antennas having a lower correlation among each other to be retransmitted from antennas having a higher correlation among each other. In another example, allocating the bit-mapped symbols allocates the bit-mapped symbols to multiple antennas according to a detection efficiency of each symbol in addition to the correlation among the multiple antennas.
