In the present invention, the terminal device may be configured with multiple RS resources to perform radio link monitoring (Radio Link Monitoring, RLM) of the terminal. Among them, one RS resource refers to a group of RSs that are periodically transmitted on a specified time-frequency resource.

The terminal device may determine a specified evaluation time T required for an RS resource to perform radio link monitoring of the terminal device based on the period of the RS resource and the constraint information of the protocol. Within a specified evaluation time T, the available RSs on RLM’s RS resources can be used to evaluate the quality of the wireless link. The number of these available RSs can be used as the RSs within the evaluation time T to evaluate the wireless link quality. quantity.

Within a specified evaluation time T, the available RSs on the RLM RS resources are a subset of all RSs on the RLM RS resources within the evaluation time T, and the terminal device detects the RSs on the available RSs.

In the present invention, within the specified evaluation time, the terminal device can specifically judge the detection condition of the reference signal (Reference Signal, RS) detected by the terminal device to determine whether it meets the specified condition.

If the specified condition is met, the terminal device may perform radio link quality evaluation processing based on the detected RS; if the specified condition is not met, the terminal device may determine that the RS is not detected, or may also determine The link quality of the detected wireless link is lower than the quality corresponding to the third quality threshold.

Specifically, the N1 or K1 may be carried through the Information Element (IE) in the RRC message, and the RRC message may be RRC messages in the prior art, for example, RRC connection reconfiguration (RRC CONNECTION RECONFIGURATION) messages, etc., this embodiment does not limit this, by extending the IE of the existing RRC message to carry the N1 or K1, or The RRC message may also be different from the existing RRC message in the prior art.

Or, for another example, the high-level signaling may be a Media Access Control (MAC) Control Element (CE) message, and specifically, the N1 or K1 may be carried by adding a new MAC CE message.

Or, for another example, the existing master information block (Master Information Block (MIB) or system information block (System Information Block, SIB) in the system broadcast message may be used to carry the N1 or K1, or a new one may be added The SIB carries the N1 or K1.

Wherein, the second threshold may be a rounding result of N2 or k2*N (such as a rounding up result or a rounding down result, etc.), where N2 is a positive integer, and N2 is less than or equal to N, for example , N=10, N2=8, the k2 is less than or equal to 1, for example, N=10, k2=0.8; the N is the number of RSs that can be used to evaluate the quality of the wireless link within a specified evaluation time.

Further, the terminal device may further pre-configure the N2 or k2, or may also obtain N2 or k2 through high-level signaling or system broadcast messages, or may use the foregoing two methods to obtain N2 or k2. The embodiment does not specifically limit this.

For example, the high-level signaling may be a radio physical resource control (Radio Resource Control, RRC) message. Specifically, the N2 or K2 may be carried through an Information Element (IE) in the RRC message, and the RRC message may be RRC messages in the prior art, for example, RRC connection reconfiguration (RRC CONNECTION RECONFIGURATION) messages, etc., this embodiment does not limit this, by extending the IE of the existing RRC messages to carry the N2 or K2, or The RRC message may also be different from the existing RRC message in the prior art.

Or, for another example, the high-layer signaling may be a Media Access Control (MAC) Control Element (CE) message, and specifically, the N2 or K2 may be carried by adding a new MAC CE message.

Or, for another example, the existing master information block (Master Information Block (MIB) or system information block (System Information Block, SIB) in the system broadcast message may be used to carry the N2 or K2, or a new one may be added The SIB carries the N2 or K2.

In general, the terminal device may specifically determine an association relationship, and then the terminal device may use measurement values of different signal qualities to correspond to different quality parameters. For example, the measured value of SINR is associated with BLER. For example, the measured value of SINR is a, and the terminal device may determine that the corresponding BLER value of a is A%. Of course, the terminal device can also directly use the measured values of SINR, RSRQ, RSRP, or RSSI to reflect the quality of the RS wireless link. For example, the measurement value of the RS signal quality (such as SINR, RSRQ, RSRP, or RSSI) is greater than a specified measurement threshold, and the specified measurement threshold may be defined as a quality parameter related to these measurement values.

For example, the third quality threshold is a BLER value; during the specified evaluation time, if the signal quality of one RS is greater than or equal to the third measurement threshold, or if the BLER value of the radio link reflected by one RS is less than or equal to A third quality threshold, the terminal device may determine that the RS is detected; if the signal quality of one RS is less than the third measurement threshold, or if the BLER value of the radio link reflected by one RS is greater than the third quality Threshold, the terminal device may determine that the RS is not detected.

In a specific implementation process, when the specified condition is met, if the signal quality of the detected RS is greater than or equal to the first measurement threshold, the terminal device may determine the link quality of the detected wireless link Higher than or equal to the quality corresponding to the first quality threshold.

In another specific implementation process, when the specified condition is satisfied, if the signal quality of the detected RS is less than the second measurement threshold, the terminal device may determine the link of the detected wireless link The quality is lower than the quality corresponding to the second quality threshold.

In another specific implementation process, if the specified RS signal quality is less than the second measurement threshold when the specified condition is not met, the terminal device may determine the detected wireless link chain The road quality is higher than or equal to the quality corresponding to the third quality threshold, and lower than the quality corresponding to the second quality threshold.
