A method for configuring a reference signal, RS, set applied in a terminal, comprising: acquiring a channel measurement result, wherein the channel measurement result comprises channel measurement parameters corresponding to n RSs in a target RS set and channel measurement parameters corresponding to m other RSs outside the target RS set, both n and m being positive integers; sending a measurement report to an access network device in response to the channel measurement result meeting a preset condition, wherein the measurement report is configured to trigger the access network device to update the target RS set; and receiving RS set update information from the access network device, wherein the RS set update information is configured to indicate RSs in the updated target RS set, characterized by the preset condition comprising any one of: the channel measurement parameter corresponding to at least one RS in the target RS set being less than a first threshold value; or the channel measurement parameter corresponding to at least one other RS in the m other RSs being greater than a second threshold value; or the channel measurement parameter corresponding to at least one RS in the target RS set being less than a third threshold value, and the channel measurement parameter corresponding to at least one other RS in the m other RSs being greater than a fourth threshold value. acquiring a channel measurement result, wherein the channel measurement result comprises channel measurement parameters corresponding to n RSs in a target RS set and channel measurement parameters corresponding to m other RSs outside the target RS set, both n and m being positive integers; sending a measurement report to an access network device in response to the channel measurement result meeting a preset condition, wherein the measurement report is configured to trigger the access network device to update the target RS set; and receiving RS set update information from the access network device, wherein the RS set update information is configured to indicate RSs in the updated target RS set, characterized by the preset condition comprising any one of: the channel measurement parameter corresponding to at least one RS in the target RS set being less than a first threshold value; or the channel measurement parameter corresponding to at least one other RS in the m other RSs being greater than a second threshold value; or the channel measurement parameter corresponding to at least one RS in the target RS set being less than a third threshold value, and the channel measurement parameter corresponding to at least one other RS in the m other RSs being greater than a fourth threshold value. the channel measurement parameter corresponding to at least one RS in the target RS set being less than a first threshold value; or the channel measurement parameter corresponding to at least one other RS in the m other RSs being greater than a second threshold value; or the channel measurement parameter corresponding to at least one RS in the target RS set being less than a third threshold value, and the channel measurement parameter corresponding to at least one other RS in the m other RSs being greater than a fourth threshold value.
