A network node applies phase ramping to channel state information reference signals and maps them to multiple beams transmitted from antenna ports for improved wireless communication.

Patentradars sammanfattning

The invention relates to a method and apparatus for handling user equipment communication in wireless networks through systematic phase ramping of Channel State Information Reference Signals (CSI-RS). The network node applies a phase ramping procedure to CSI-RS, generates beamforming weights based on the phase-ramped signals, and maps these to one or more beams transmitted from multiple physical antenna ports. This technique enables dynamic beam steering, improved signal control, and enhanced channel estimation in advanced wireless systems including 5G and beyond.
