Further, the main module may obtain a plurality of beam numbers for a plurality of SS Block beam numbers, where one SS Block beam corresponds to one beam number, and different SS Block beams correspond to different beam numbers, because one antenna array corresponds to at least one SS Block beam, and different antenna array corresponds to at least one SS Block beam, that is, one antenna array corresponds to at least one beam number.

For example, referring to fig. 6, fig. 6 is a schematic application scenario diagram of an antenna control device according to an embodiment of the present application. When the main module 610 includes: a first antenna array plane 611, a second antenna array plane 612, a third antenna array plane 613, and a fourth antenna array plane 614; wherein, the first antenna array plane 611 corresponds to the SS Block beam 1, the second antenna array plane 612 corresponds to the SS Block beam 2, the third antenna array plane 613 corresponds to the SS Block beam 3, and the fourth antenna array plane 614 corresponds to the SS Block beam 4; that is, when one antenna array plane corresponds to one SS Block beam, the main module can select the home array plane of the first UE based on different scheduling strategies, for example, when each transceiver channel of the main module scans the SS Block beam through time division, if it is determined that downlink radio frequency signals of 4 transceiver channels of the first UE620 in the direction of the antenna array plane 614 are all strong, the SS Block beam 4 can be selected to cover the first UE620, that is, downlink radio frequency signals (such as PDSCH service) between the base station and the first UE are scheduled on the fourth antenna array plane 614.

In still another possible implementation manner of the embodiment of the present application, in a case where a channel state information-Reference Signal (CSI-RS) measurement is configured, when a primary module is in communication connection with a first UE, the first UE may determine antenna array plane assignment of the first UE based on the CSI-RS.

For example, when the main module includes: the first antenna array surface, the second antenna array surface, the third antenna array surface and the fourth antenna array surface; the first antenna array surface corresponds to the CSI-RS beam 1, the second antenna array surface corresponds to the CSI-RS beam 2, the third antenna array surface corresponds to the CSI-RS beam 3 and the fourth antenna array surface corresponds to the CSI-RS beam 4; when a first UE determines that a CSI-RS beam corresponding to an antenna array surface 614 closest to the first UE is a CSI-RS beam 4 through CSI-RS measurement, it is determined that the first UE is covered by the CSI-RS beam 4, that is, downlink radio frequency signals (e.g., PDSCH services) between a base station and the first UE are scheduled to the fourth antenna array surface 614.

The second implementation is described in detail below:

and the receiving and transmitting channel units in each receiving and transmitting channel of the main module scan signals through time division to determine a plurality of first antenna objects, wherein the plurality of first antenna objects are antenna objects with path signals higher than a preset value between the plurality of antenna objects corresponding to the main module and the second UE, the plurality of antenna objects can be antenna objects on different antenna array surfaces, and the second UE is covered by the plurality of first antenna objects so as to realize the receiving and transmitting of uplink and downlink physical channels through the plurality of antenna objects of the plurality of antenna array surfaces.

In a possible implementation manner of the embodiment of the present application, one CSI-RS beam corresponds to multiple directional antennas of multiple antenna array planes, and when the main module is in communication connection with the second UE, a transceiver channel unit in each transceiver channel of the main module can determine multiple first directional antennas through antenna scanning, where the multiple first directional antennas are directional antennas, where path signals between multiple directional antennas corresponding to the main module and the second UE are higher than a preset value; and the uplink and downlink physical channels are transmitted and received through the plurality of first directional antennas (the directional antennas can be different antenna array planes).

Here, for multiple transceiving channels, each CSI-RS beam may correspond to a portion of the directional antennas of multiple antenna array planes. For example, the main module includes four antenna planes, each with 4 directional antennas, and the CSI-RS beam 1 may correspond to the directional antennas 3, 4 of the antenna plane 1 and the directional antennas 1, 2 of the antenna plane 2; the CSI-RS beam 4 corresponds to directional antennas 1, 3, 4 of the antenna array plane 1, 2 and 4. The method for scheduling the plurality of CSI-RS beams can define a plurality of beams through an algorithm according to multipath channel characteristics of different building environments, select different antenna array planes for transmitting, and maximally improve the space multi-stream capacity. That is, in this embodiment, for each CSI-RS beam, the antenna selection control unit may be controlled to select a portion of antennas corresponding to a plurality of different antenna planes, thereby improving the spatial multiflow capability and the inter-cell interference resistance.

For example, referring to fig. 7, fig. 7 is a schematic application scenario diagram of another antenna control device according to an embodiment of the present application. Taking four directional antennas per plane as an example, the main module 710 is communicatively connected with the second UE720, if the channel detection finds that the paths from the directional antennas A1 and A2 of the antenna plane 711 to the second UE are strong, but the directional antennas A3 and A4 have high correlation with the directional antennas A1 and A2, and the paths from the directional antennas A3 and A4 of the antenna plane 712 to the UE are also strong and have low correlation with the directional antennas A1 and A2 of the antenna plane 711, the directional antennas A1 and A2 of the antenna plane 711 and the directional antennas A3 and A4 of the antenna plane 712 can be selected, so that the CSI-RS beams corresponding to the directional antennas A2 and A3 and A4 of the antenna plane 711 cover the UE, that is, the base station will schedule downlink radio frequency signals (such as PDSCH traffic) between the base station and the first UE to the directional antennas A1 and A2 of the antenna plane 712, and the directional antennas A3 and A4 of the antenna plane 712, as shown in fig. 8, a schematic diagram between the user equipment and the base station in this case is shown.

It can be seen that in the embodiment of the present application, a plurality of antenna objects are deployed on a side surface of a main module in an antenna control device to obtain a plurality of antenna array planes, and by selecting the plurality of antenna array planes or directly selecting the plurality of antenna objects, the benefit of omni-directional coverage is obtained, the EIRP is increased, the number of main modules is reduced, and then the total station cost is reduced.
