BASE STATION DEVICE, CONTROL METHOD, AND PROGRAM FOR IMPROVING CHANNEL ESTIMATION IN WIRELESS COMMUNICATION

Title:

BASE STATION DEVICE, CONTROL METHOD, AND PROGRAM FOR IMPROVING CHANNEL ESTIMATION IN WIRELESS COMMUNICATION

Document Type and Number:

WIPO Patent Application WO/2024/070790

Kind Code:

A1

Abstract:

This base station device notifies a terminal device of first information that specifies an orthogonal cover code (OCC) used when generating a demodulation reference signal (DMRS) to be transmitted to a terminal device connected to the base station device and a resource element for transmitting the DMRS, and second information that allows the terminal device to specify whether channel estimation is possible in units of sub-bands that are part of the band in which channel estimation is performed by means of the DMRS, and transmits the DMRS and data for the terminal device in the band.
