Abstract

Claims (13)

1 . A terminal comprising:

a receiving section that receives a channel state information reference signal (CSI-RS); and

a control section that performs, by using a machine learning model trained based on first configuration of the CSI-RS, control of performing prediction based on second configuration of the CSI-RS,

wherein a density of the CSI-RS of the second configuration is lower than a density of the CSI-RS of the first configuration.

2 . The terminal according to claim 1 , wherein the control section determines a resource of the CSI-RS of the second configuration by sampling a resource of the CSI-RS of the first configuration.

3 . A radio communication method for a terminal, the radio communication method comprising:

receiving a channel state information reference signal (CSI-RS); and

performing control of performing, by using a machine learning model trained based on first configuration of the CSI-RS, prediction based on second configuration of the CSI-RS,

wherein a density of the CSI-RS of the second configuration is lower than a density of the CSI-RS of the first configuration.

4 . A base station comprising:

a transmitting section that transmits a channel state information reference signal (CSI-RS) based on first configuration for training of a machine learning model; and

a control section that performs, for input of the machine learning model trained based on the first configuration, control of transmitting the CSI-RS based on second configuration,

wherein a density of the CSI-RS of the second configuration is lower than a density of the CSI-RS of the first configuration.
