Abstract
A link quality monitoring method performed by a mobile terminal includes the following steps: performing, by the mobile terminal, detection for a pre-configured radio link monitoring reference signal to determine whether the radio link monitoring reference signal is received; and reporting, by the mobile terminal, based on whether the radio link monitoring reference signal is received, in-synchronization or out-of-synchronization used to indicate radio link quality of the radio link used by the mobile terminal.

A link quality monitoring method comprising:
- performing, by a terminal, detection for a pre-configured radio link monitoring reference signal (RLM-RS) to determine whether the RLM-RS is received;
- and
- reporting, by the terminal, based on whether the RLM-RS is received, in-synchronization (in-sync) or out-of-synchronization (out-of-sync) used to indicate link quality,
- wherein the step of reporting, by the terminal, based on whether the RLM-RS is received, in-sync or out-of-sync used to indicate link quality comprises:
- when one such RLM-RS is received, estimating, by the terminal, a hypothetical physical downlink control channel block error rate (PDCCH-BLER) corresponding to the received RLM-RS;
- or
- when one such RLM-RS is not received, skipping, by the terminal, estimating a hypothetical PDCCH-BLER corresonding to the unreceived RLM-RS;
- and
- reporting, by the terminal, the in-sync or out-of-sync used to indicate link quality, based on an estimation result of the hypothetical PDCCH-BLER corresponding to the received RLM-RS and a quantity of unreceived RLM-RSs;
- or
- reporting, by the terminal, the in-sync or out-of-sync used to indicate link quality, based on a quantity of unreceived RLM-RSs.
A terminal, comprising a processor, a memory, and a computer program that is stored in the memory and capable of running on the processor, wherein when the computer program is executed by the processor, the steps of a link quality monitoring method are implemented, the link quality monitoring method comprising:
- performing, by the terminal, detection for a pre-configured radio link monitoring reference signal (RLM-RS) to determine whether the RLM-RS is received;
- and
- reporting, by the terminal, based on whether the RLM-RS is received, in-synchronization (in-sync) or out-of-synchronization (out-of-sync) used to indicate link quality,
- wherein the step of reporting, y the terminal, based on whether the RLM-RS is received, in-sync or out-of-sync used to indicate link quality comprises:
- when one such RLM-RS is received, estimating, by the terminal, a hypothetical physical downlink control channel block error rate (PDCCH-BLER) corresponding to the received RLM-RS;
- or
- when one such RLM-RS is not received, skipping, by the terminal, estimating a hypothetical PDCCH-BLER corresponding to the unreceived RLM-RS;
- and
- reporting, by the terminal, the in-sync or out-of-sync used to indicate link quality, based on an estimation result of the hypothetical PDCCH-BLER corresponding to the received RLM-RS and a quantity of unreceived RLM-RSs;
- or
- reporting, by the terminal, the in-sync or out-of-sync used to indicate link quality, based on a quantity of unreceived RLM-RSs.
A non-transitory computer-readable storage medium, wherein the non-transitory computer-readable storage medium stores a computer program therein, and when the computer program is executed by a processor of a terminal, the steps of a link quality monitoring method are implemented, the link quality monitoring method comprising:
- performing, by the terminal, detection for a pre-configured radio link monitoring reference signal (RLM-RS) to determine whether the RLM-RS is received;
- and
- reporting, by the terminal, based on whether the RLM-RS is received, in-synchronization (in-sync) or out-of-synchronization (out-of-sync) used to indicate link quality,
- wherein the step of reporting, by the terminal, based on whether the RLM-RS is received, in-sync or out-of-sync used to indicate link quality comprises:
- when one such RLM-RS is received, estimating, by the terminal, a hypothetical physical downlink control channel block error rate (PDCCH-BLER)) corresponding to the received RLM-RS;
- or
- when one such RLM-RS is not received, skipping, by the terminal, estimating a hypothetical PDCCH-BLER corresponding to the unreceived RLM-RS;
- and
- reporting, by the terminal, the in-sync or out-of-sync used to indicate link quality, based on an estimation result of the hypothetical PDCCH-BLER corresponding to the received RLM-RS and a quantity of unreceived RLM-RSs;
- or
- reporting, by the terminal, the in-sync or out-of-sync used to indicate link quality, based on a quantity of unreceived RLM-RSs.
