Reporting maximum duration of a joint channel estimation

Abstract

A method for reporting a maximum duration of joint channel estimation includes: receiving a first message sent by a network side device, the first message being used for instructing the terminal device to report the maximum duration of the joint channel estimation; and sending the maximum duration to the network side device. The terminal device reports the maximum duration of the joint channel estimation, so as to enable the network side device to take the maximum duration as a reference value of the time window for the joint channel estimation of the terminal, and configure a length of the time window for a retransmission of the joint channel estimation for the terminal device based on the reference value.
