Abstract
Systems and methods are provided for utilizing antenna arrays with digital beamforming. An array-based system may have a plurality of antenna elements arranged in a two-dimensional array, and a plurality of transceiver chips configured for handling transmission and reception of radio frequency (RF) signals via the plurality of antenna elements. A number of transceiver chips in the plurality of transceiver chips may be less than a number of antenna elements in the plurality of antenna elements. The plurality of transceiver chips is configured to control operation of the plurality of antenna elements such that digital or hybrid beamforming is enabled during the transmission and reception of RF signals via the plurality of antenna elements.
Claims20
A system, comprising:
- a plurality of antenna elements arranged in two-dimensional array;
- a plurality of transceiver chips configured for handling transmission and reception of radio frequency (RF) signals via the plurality of antenna elements;
- wherein:
- a number of transceiver chips in the plurality of transceiver chips is less than a number of antenna elements in the plurality of antenna elements;
- and
- the plurality of transceiver chips is configured to control operation of the plurality of antenna elements such that digital or hybrid beamforming is enabled during the transmission and reception of RF signals via the plurality of antenna elements.
A transceiver chip configured for handling transmission and reception of radio frequency (RF) signals via two or more antenna elements from a plurality of antenna elements in an array-based system;
- the transceiver chip comprising:
- a plurality of circuits that comprise at least at least two sets of circuits corresponding to the two or more antenna elements;
- wherein:
- each set of circuits is configured for handling signals transmitted and received via a corresponding antenna element;
- and
- the transceiver chip is configured to control operation of the two or more antenna elements such that digital or hybrid beamforming is enabled during the transmission and reception of RF signals via the plurality of antenna elements.
