Definitions
- the first processing unit is configured to split the array antenna and form a first direction in the downlink direction. a transmit beam and a second transmit beam, the first transmit beam covers the first cell, and the second transmit beam covers the second cell;
- the base station weights the array antenna to form a receive beam.
- the sub-antenna array for example, selects 4 antenna arrays from the antenna array of the array antenna for uplink 4 reception. If 2 is used, 2 antenna arrays can be selected.
- the first UE is located in the first cell, and the second UE is located in the second cell.
- the first processing unit 301 is configured to split the array antenna, and in the downlink direction, form a first transmit beam and a second transmit beam, where the first transmit beam covers the first cell, and the second transmit beam covers the second cell.
- the second processing unit 302 can perform wide beamforming on the array antenna, that is, map the 8 physical antennas of the array antenna into 4 antenna ports, and simultaneously set the antenna beam width from about 90 degrees.
- the beam width is changed to about 65 degrees, which is consistent with the beam width of the conventional four antennas.
- the first UE is located in the first cell, and the second UE is located in the second cell.
