Abstract
An operation method of a terminal using a channel estimation artificial intelligence (AI) model may comprise: receiving, from a base station, information on the channel estimation AI model; performing first channel estimation using the channel estimation AI model by receiving a first signal A from a base station; and receiving, from the base station, data based on the estimated channel.

An operation method of a terminal using a channel estimation artificial intelligence (AI) model in a communication system, the operation method comprising:
- transmitting, to a base station, a signal indicating application of the channel estimation AI model of the terminal;
- receiving, from the base station, density reduction configuration information for a first signal A, wherein the first signal A is generated by reducing a density of a signal A received from the base station, and wherein the density reduction configuration information includes information on a resource reduction unit and information on a density reduction level for generating the first signal A from the signal A;
- performing first channel estimation using the channel estimation AI model by receiving the first signal A based on the density reduction configuration information from the base station;
- and
- receiving, from the base station, data based on the estimated channel.
