Method and apparatus for generating reference signal in analog/digital mixed BF system |
| 摘要 |
A millimeter radio wave communication system. In a method for operating a base station (BS) in an analog/digital mixed BF system, an analog BF direction is determined. A digital BF precoder is determined for the determined analog BF direction. Digital BF precoding is performed using the digital BF precoder with respect to the determined analog BF direction. A DownLink Reference Signal (DL RS) is transmitted in the analog BF direction on which the digital BF precoding has been performed. |

1. A method for operating a base station (BS) in an analog/digital mixed BF system, the method comprising:
determining an analog beamforming (BF) direction; determining a digital BF precoder for the determined analog BF direction; performing digital BF precoding using the digital BF precoder with respect to the determined analog BF direction; and transmitting a downlink reference signal (DL RS) in the analog BF direction on which the digital BF precoding has been performed. |
