US 2026/0269898 A1 · COORDINATION FOR SMOOTH BEAMFORMING

Abstract

This disclosure provides methods, components, devices and systems for beamforming. Some aspects more specifically relate to techniques to reduce phase misalignment and delay spread to beamformed messages such that a receiving device may apply channel smoothing filtering to the received beamformed message. In some examples, the transmitting device may ensure that the delay spread of the steered channel for a beamformed message is roughly matching the delay spread of an open-loop channel. The transmitting device may signal for the receiving device to perform channel smoothing filtering to a received beamformed message, for example, because the transmitting device applies techniques to reduce the phase misalignment and delay spread to the beamformed message. In some examples, based on the indication, the receiving device may apply channel smoothing filtering to a beamformed transmission received from the transmitting device.
