Patent ID: 11528062

Abstract:
The present disclosure aims to provide a method and device for virtual port mapping of massive MIMO. The present disclosure maps one or more transceiver units to a virtual port by performing hybrid beamforming for at least one transceiver unit in massive MIMO, and then performs digital precoding based on the virtual port. Compared with the prior art, the present disclosure is an adaptive technology adapted to the existing architecture; the present disclosure is based on virtual port mapping technology, which reduces the number of ports required for baseband processing, thus simplifying baseband processing, and furthermore, the present disclosure does not reduce the number of antenna elements utilized; the present disclosure can utilize digital precoding in hybrid beamforming to perform energy efficiency management; the present disclosure can be used more flexibly as a medium-term beamforming scheme in different frequency domain and time domain, while traditional analog beamforming is a long-term/semi-static beamforming scheme in time domain.
