Method for link quality monitoring and related products
View Patent ↗A method for link quality monitoring and related products are provided in implementations of the present disclosure. The method includes the following. A first radio link monitoring reference signal (RLM-RS) resource is obtained, where the first RLM-RS resource is a resource among M first RLM-RS candidate resources, and K first RLM-RS candidate resources among the M first RLM-RS candidate resources are used to transmit a first RLM-RS, M and K are positive integers, and K≤M. Radio link quality monitoring is performed according to the first RLM-RS resource.
1. A method for link quality monitoring, being applicable to a terminal device and comprising:
obtaining a first radio link monitoring reference signal (RLM-RS) resource, wherein the first RLM-RS resource is a resource among M first RLM-RS candidate resources, and K first RLM-RS candidate resources among the M first RLM-RS candidate resources are used to transmit a first RLM-RS, M and K are positive integers, and K≤M;
performing radio link quality monitoring according to the first RLM-RS resource, wherein the first RLM-RS resource comprises K first RLM-RS candidate resources with worst channel quality among the M first RLM-RS candidate resources; and
determining that none of the M first RLM-RS candidate resources is for transmitting the first RLM-RS, according to a detection result of the first RLM-RS on the M first RLM-RS candidate resources.
2. The method of claim 1 , wherein the K first RLM-RS candidate resources among the M first RLM-RS candidate resources being used to transmit the first RLM-RS comprising:
if more than K or K first RLM-RS candidate resources among the M first RLM-RS candidate resources have a channel availability, K first RLM-RS candidate resources having the channel availability among the M first RLM-RS candidate resources are used to transmit the first RLM-RS; or
if less than K first RLM-RS candidate resources among the M first RLM-RS candidate resources have the channel availability, a first RLM-RS candidate resource having the channel availability among the M first RLM-RS candidate resources is used to transmit the first RLM-RS.
3. The method of claim 1 , wherein performing the radio link quality monitoring according to the first RLM-RS resource comprises:
evaluating, in an in-sync (IS) evaluation period, whether downlink (DL) radio link quality estimated on the first RLM-RS resource is higher than an IS threshold.
4. The method of claim 3 , wherein the M RLM-RS candidate resources are in a first discovery reference signal (DRS) transmission window.
5. The method of claim 4 , wherein the IS evaluation period is an integer multiple of a period of the first DRS transmission window.
6. The method of claim 1 , wherein performing the radio link quality monitoring according to the first RLM-RS resource comprises:
determining, in an out-of-sync (OOS) evaluation period, whether DL radio link quality estimated on the first RLM-RS resource is lower than an OOS threshold.
7. The method of claim 6 , wherein the M RLM-RS candidate resources are in a second DRS transmission window.
8. The method of claim 7 , wherein the OOS evaluation period is an integer multiple of a period of the second DRS transmission window.
9. The method of claim 1 , wherein the first RLM-RS resource comprises a synchronization signal block (SSB) resource and/or a channel state information reference signal (CSI-RS) resource.
10. A terminal device, comprising:
a processor; and
a memory configured to store one or more programs;
wherein the processor is configured to execute the one or more programs stored in the memory to:
obtain a first radio link monitoring reference signal (RLM-RS) resource, wherein the first RLM-RS resource is a resource among M first RLM-RS candidate resources, and K first RLM-RS candidate resources among the M first RLM-RS candidate resources are used to transmit a first RLM-RS, M and K are positive integers, and K≤M;
perform radio link quality monitoring according to the first RLM-RS resource, wherein the first RLM-RS resource comprises K first RLM-RS candidate resources with worst channel quality among the M first RLM-RS candidate resources; and
determine that none of the M first RLM-RS candidate resources is for transmitting the first RLM-RS, according to a detection result of the first RLM-RS on the M first RLM-RS candidate resources.
11. The terminal device of claim 10 , wherein the K first RLM-RS candidate resources among the M first RLM-RS candidate resources being used to transmit the first RLM-RS comprising:
if more than K or K first RLM-RS candidate resources among the M first RLM-RS candidate resources have a channel availability, K first RLM-RS candidate resources having the channel availability among the M first RLM-RS candidate resources are used to transmit the first RLM-RS; or
if less than K first RLM-RS candidate resources among the M first RLM-RS candidate resources have the channel availability, a first RLM-RS candidate resource having the channel availability among the M first RLM-RS candidate resources is used to transmit the first RLM-RS.
12. A non-transitory computer-readable storage medium configured to store computer programs for electronic data interchange, the computer programs being operable with a computer to perform the method of claim 1 .
