Abstract

A method for configuring a reference signal (RS) set includes: acquiring, by a terminal, a channel measurement result; sending, by the terminal a measurement report to an access network device in response to the channel measurement result meeting a preset condition; updating, by the access network device, a target RS set based on the measurement report; and sending, by the access network device, RS set update information to the terminal.

First claim

What is claimed is:

1 . A method for configuring a reference signal (RS) set, comprising:
acquiring, by a terminal, 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, wherein the target RS set is a set of RSs configured to detect a beam failure, and the m other RSs are candidate RSs for updating RSs in the target RS set; sending, by the terminal, 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, by the terminal, 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, wherein the preset condition comprises: the channel measurement parameter corresponding to at least one RS in the target RS set being less than the first threshold value, and the channel measurement parameter corresponding to at least one RS in the m other RSs being greater than a second threshold value, the method further comprising: receiving, by the terminal, configuration information from the access network device, wherein the configuration information comprises measurement object configuration information and report content configuration information.

2 . The method according to claim 1 , wherein the measurement report comprises identification information of k RSs and indication information of the channel measurement parameters corresponding to the k RSs, k being an integer greater than 1;
wherein the k RSs comprise the n RSs and at least one RS, with the channel measurement parameter being greater than the channel measurement parameter corresponding to a target RS, in the m other RSs, the target RS being an RS with a minimum channel measurement parameter in the n RSs.

3 . The method according to claim 2 , wherein
in the k RSs, the indication information of the channel measurement parameter corresponding to an optimal RS is represented by a number of a bits, the optimal RS being an RS with a maximum channel measurement parameter in the k RSs, a being a positive integer; in the k RSs, the indication information of the channel measurement parameter corresponding to each remaining RS other than the optimal RS is represented by b bits, b being a positive integer; and the indication information of the channel measurement parameter corresponding to an i th remaining RS is configured to indicate a difference between the channel measurement parameter corresponding to the i th remaining RS and the channel measurement parameter corresponding to the optimal RS, or to indicate that the channel measurement parameter corresponding to the i th remaining RS is less than a present threshold, i being a positive integer.

4 . The method according to claim 1 , wherein the preset condition comprises:
the first W RSs of all the RSs included in the channel measurement result, ranked based on the channel measurement parameters in a descending order being different from the channel measurement results previously acquired, w being a positive integer; or a sum of the channel measurement parameter corresponding to at least one RS in the target RS set and a preset offset being less than a maximum value of the channel measurement parameters corresponding to the m other RSs.

5 . The method according to claim 1 ,
wherein the measurement object configuration information is configured to indicate an RS that needs to acquire the channel measurement parameter, and the report content configuration information is configured to indicate content that needs to be contained when the measurement report is sent to the access network device.

6 . A method for configuring a reference signal (RS) set, comprising:
receiving, by an access network device, a measurement report, wherein the measurement report is sent by a terminal in response to a channel measurement result meeting a preset condition, the channel measurement result comprising 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, wherein the target RS set is a set of RSs configured to detect a beam failure, and the m other RSs are candidate RSs for updating RSs in the target RS set; updating, by the access network device, the target RS set based on the measurement report; and sending, by the access network device, RS set update information to the terminal, wherein the RS set update information is configured to indicate RSs in the updated target RS set, wherein the preset condition comprises the channel measurement parameter corresponding to at least one RS in the target RS set being less than the first threshold value, and the channel measurement parameter corresponding to at least one RS in the m other RSs being greater than a second threshold value, the method further comprising: sending, by the access network device, configuration information to the terminal, wherein the configuration information comprises measurement object configuration information and report content configuration information.

7 . The method according to claim 6 , wherein the measurement report comprises identification information of k RSs and indication information of the channel measurement parameters corresponding to the k RSs, k being an integer greater than 1;
wherein the k RSs comprise the n RSs and at least one RS, with the channel measurement parameter being greater than the channel measurement parameter corresponding to a target RS, in the m other RSs, the target RS being an RS with a minimum channel measurement parameter in the n RSs.

8 . The method according to claim 7 , wherein said updating, by the access network device, the target RS set based on the measurement report comprises:
adding, by the access network device, at least one RS of the m other RSs to the target RS set, and/or deleting at least one RS from the target RS set; wherein the channel measurement parameter corresponding to the RS added to the target RS set is greater than the channel measurement parameter corresponding to the RS deleted from the target RS set.

9 . The method according to claim 6 ,
wherein the measurement object configuration information is configured to indicate an RS that needs to acquire the channel measurement parameter, and the report content configuration information is configured to indicate content that needs to be contained when the measurement report is sent to the access network device.

10 . A terminal, comprising:
a processor; and memory for storing an instruction executable by the processor; wherein the processor is configured to: acquire 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, wherein the target RS set is a set of RSs configured to detect a beam failure, and the m other RSs are candidate RSs for updating RSs in the target RS set; send 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 receive RS set update information fro
