Abstract
A network node includes an antenna array having a plurality of antenna sub-arrays. A switching device is coupled to the antenna array, the switching device being configured to connect at least two input signals to respective ones of the plurality of antenna sub-arrays. A processor is configured to determine a channel capacity, wherein based on the channel capacity, the processor is configured to control the switching device to switch a connection of the at least two input signals to different ones of the plurality of antenna sub-arrays to change one or more of an inter-distance between the respective ones of the plurality of antenna sub-arrays and a down-tilting angle of the antenna array.
Claims12
A network node, comprising:
- an antenna array having a plurality of antenna sub-arrays;
- a switching device coupled to the antenna array, the switching device being configured to connect at least two input signals to respective ones of the plurality of antenna sub-arrays corresponding to a selected antenna configuration mode;
- and
- a processor configured to determine a channel capacity, wherein based on the channel capacity, the processor is configured to:
- receive a desired channel capacity of the antenna array;
- compare the determined channel capacity with the desired channel capacity of the antenna array;
- select an antenna configuration mode corresponding to the determined channel capacity that is larger than the desired channel capacity;
- control the switching device to switch a connection of the at least two input signals to different ones of the plurality of antenna sub-arrays corresponding to the selected antenna configuration mode that corresponds to the determined channel capacity that is larger than the desired channel capacity, to change one or more of an inter-distance between the respective ones of the plurality of antenna sub-arrays and a down-tilting angle of the antenna array.
A method performed by a network node, comprising:
- determining a channel capacity;
- receive a desired channel capacity of an antenna array;
- compare the determined channel capacity with the desired channel capacity of the antenna array;
- select an antenna configuration mode corresponding to the determined channel capacity that is larger than the desired channel capacity;
- and
- controlling a switching device to switch a connection of at least two input signals to different ones of a plurality of antenna-subarrays of an antenna array corresponding to the selected antenna configuration mode, to change one or more of an inter-distance between respective ones of the plurality of antenna sub-arrays and a down-tilting angle of the antenna array.
