Description

Detection method of wireless link and terminal equipment

Technical Field

The embodiment of the application relates to the technical field of communication, in particular to a wireless link detection method and terminal equipment.

Background

In New Radio (NR) systems, such as 5G applications, unlicensed spectrum may be used, i.e., communications are conducted using NR techniques on channels of the unlicensed spectrum. In order for various wireless communication systems using unlicensed spectrum for wireless communication to coexist friendly on the spectrum, some countries or regions stipulate regulatory requirements that must be met using unlicensed spectrum. For example, in european areas, the communication device follows the principle of "listen-before-talk" (LBT), that is, before the communication device performs signal transmission on the channel of the unlicensed spectrum, it needs to perform channel sensing on the channel of the unlicensed spectrum, and only when the channel sensing result is that the channel is idle, the communication device can perform signal transmission; if the channel sensing result is that the channel is busy, the communication device can not transmit signals.

However, since the signal transmission mode based on the LBT principle no longer depends on the receiving end and the transmitting end of the signal, but also depends on the channel condition of the wireless link, it is necessary to provide a method for detecting the wireless link for the new transmission method to achieve the correct detection of the wireless link.

210. Within a specified evaluation time, if the detection condition of a Reference Signal (RS) detected by a terminal device meets a specified condition, the terminal device carries out evaluation processing of the quality of a wireless link according to the detected RS.

In this way, if the detection condition of the RS detected by the terminal device satisfies the specified condition within the specified evaluation time, the terminal device can perform the evaluation processing of the radio link quality according to the detected RS, and can be adapted to the detection of the radio link that performs signal transmission by using any signal transmission mode, for example, the detection of the radio link that uses the signal transmission mode based on the LBT principle in the 5G application, and the like, thereby improving the reliability of the radio link detection.

In the present invention, the terminal device may be configured with a plurality of RS resources to perform Radio Link Monitoring (RLM) of the terminal. One RS resource refers to a group of RS that periodically transmits on a designated time-frequency resource.

The terminal device may determine a specified evaluation time T required for the RS resource to perform radio link monitoring of the terminal device based on the period of the RS resource and constraint information of the protocol. During a specified evaluation time T, available RSs on the RS resource of the RLM can be used for evaluating the RS of the radio link quality, and the quantity of the available RSs is used as the quantity of the RSs which can be used for evaluating the radio link quality in the evaluation time T.

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

In the present invention, within the specified evaluation time, the terminal device may specifically determine a detection condition of a Reference Signal (RS) detected by the terminal device, and determine whether the detection condition satisfies a specified condition.

If the specified condition is met, the terminal equipment can perform the evaluation processing of the quality of the wireless link according to 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 that the link quality of the detected radio link is lower than the quality corresponding to the third quality threshold.

The third Quality threshold may be at least one of a Block Error Rate (BLER) value, a Signal to Interference Noise Ratio (SINR) value, a Reference Signal Receiving Quality (RSRQ) value, a Reference Signal Receiving Power (RSRP) value, and a Received Signal Strength Indication (RSSI) value, and is not particularly limited in this embodiment.

Optionally, in a possible implementation manner of this embodiment, the specified condition may include, but is not limited to, at least one of the following conditions:

the number of times that the RS is detected is greater than or equal to a first threshold; and

the number of times that the RS is not detected is less than or equal to the second threshold.

Wherein, the first threshold may be N1, a rounding result of k1 × N (e.g., a rounding-up result or a rounding-down result), etc., the N1 is a positive integer, the N1 is less than or equal to N, e.g., N — 10, N1 — 8, the k1 is less than or equal to 1, e.g., N — 10, k1 is 0.8; the N is the number of RSs available to evaluate the radio link quality within a specified evaluation time.

Further, the terminal device may further pre-configure the N1 or k1, or may further acquire N1 or k1 through a higher layer signaling or a system broadcast message, or may also acquire N1 or k1 by using the foregoing two manners, which is not limited in this embodiment.

For example, the higher layer signaling may be a Radio Resource Control (RRC) message, specifically, the N1 or the K1 may be carried by an Information Element (IE) in an RRC message, and the RRC message may be an RRC message in the prior art, for example, an RRC CONNECTION RECONFIGURATION (RRC CONNECTION RECONFIGURATION) message and the like, which is not limited in this embodiment, and the N1 or the K1 is carried by extending an IE of an existing RRC message, or the RRC message may also be an RRC message different from an existing RRC message in the prior art.

Or, for another example, the higher layer 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.

For another example, the N1 or K1 may be carried by an existing Master Information Block (MIB) or System Information Block (SIB) in the System broadcast message, or a new SIB carrying the N1 or K1 may be added.

Wherein, the second threshold may be N2, a rounding result of k2 × N (e.g., a rounding-up result or a rounding-down result), etc., the N2 is a positive integer, the N2 is less than or equal to N, e.g., N — 10, N2 — 8, the k2 is less than or equal to 1, e.g., N — 10, k2 is 0.8; the N is the number of RSs available to evaluate the radio link quality within a specified evaluation time.

Further, the terminal device may further pre-configure the N2 or k2, or may further acquire N2 or k2 through a higher layer signaling or a system broadcast message, or may also acquire N2 or k2 by using the foregoing two manners, which is not limited in this embodiment.

For example, the higher layer signaling may be a Radio Resource Control (RRC) message, specifically, the N2 or the K2 may be carried by an Information Element (IE) in an RRC message, and the RRC message may be an RRC message in the prior art, for example, an RRC CONNECTION RECONFIGURATION (RRC CONNECTION RECONFIGURATION) message and the like, which is not limited in this embodiment, and the N2 or the K2 is carried by extending an IE of an existing RRC message, or the RRC message may also be an RRC message different from an existing RRC message in the prior art.

Or, for another example, the higher 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.

For another example, the N2 or K2 may be carried by an existing Master Information Block (MIB) or System Information Block (SIB) in the System broadcast message, or a new SIB carrying the N2 or K2 may be added.

In a specific implementation procedure, within the specified evaluation time, if the signal quality of an RS is greater than or equal to a third measurement 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, the terminal device may determine that the RS is not detected.

The third measurement threshold may be at least one of a Signal to Interference plus Noise Ratio (SINR) value, a Reference Signal Receiving Quality (RSRQ) value, a Reference Signal Receiving Power (RSRP) value, and a Received Signal Strength Indication (RSSI) value, which is not particularly limited in this embodiment.

In another specific implementation procedure, within the specified evaluation time, if the link quality of the radio link reacted by an RS is higher than or equal to the quality corresponding to the third quality threshold, the terminal device may determine that the RS is detected; if the link quality of the radio link reacted by one RS is lower than the quality corresponding to the third quality threshold, the terminal device may determine that the RS is not detected.

Generally, a terminal device may specifically determine an association relationship, and then the terminal device may use the measured values of different signal qualities to correspond to different quality parameters. For example, a measured SINR value is associated with BLER, e.g., the measured SINR value is a, and the terminal device may determine that a corresponds to a% BLER value. Of course, the terminal device may directly reflect the quality of the RS radio link by using the measurement value of SINR, RSRQ, RSRP, RSSI, or the like. For example, the measured value of the signal quality of the RS (e.g., SINR, RSRQ, RSRP, or RSSI) is greater than a specified measurement threshold, which may then be defined as a quality parameter associated with the measured values.

For example, the third quality threshold is a BLER value; within the specified evaluation time, if the signal quality of one RS is greater than or equal to a 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.

Or, for another example, the third quality threshold is at least one of an SINR value, an RSRQ value, an RSRP value, and an RSSI value; within the specified evaluation time, if the signal quality of one RS is greater than or equal to a third measurement threshold, or if at least one of the SINR value, RSRQ value, RSRP value, and RSSI value of the wireless link reacted by one RS is greater 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 at least one of the SINR value, RSRQ value, RSRP value, and RSSI value of the wireless link reacted by one RS is less than the third quality threshold, the terminal device may determine that the RS is not detected.

Optionally, in a possible implementation manner of this embodiment, in 210, the terminal device may specifically determine the signal quality of the detected RS and a first measurement threshold, so as to perform an evaluation process of the radio link quality.

In this implementation, the terminal device may specifically perform filtering processing on the received multiple RSs within a specified evaluation time to obtain signal quality, e.g., average power value, of the detected RSs.

In a specific implementation procedure, if the signal quality of the detected RS is greater than or equal to the first measurement threshold under the condition that a specified condition is satisfied, the terminal device may determine that the link quality of the detected radio link is greater than or equal to the quality corresponding to the first quality threshold.

In another specific implementation procedure, if the signal quality of the detected RS is less than the second measurement threshold under the condition that a specified condition is satisfied, the terminal device may determine that the link quality of the detected radio link is lower than a quality corresponding to the second quality threshold.

In another specific implementation process, if the signal quality of the detected RS is less than the second measurement threshold under the condition that the specified condition is not met, the terminal device may determine that the link quality of the detected radio link 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.

In another specific implementation procedure, if the signal quality of the detected RS is greater than or equal to a second measurement threshold and lower than the first measurement threshold, the terminal device may determine that the link quality of the detected radio link is greater than or equal to the quality corresponding to the second quality threshold and lower than the quality corresponding to the first quality threshold.

In this embodiment, if the detection condition of the RS detected by the terminal device satisfies the specified condition within the specified evaluation time, the terminal device may perform the evaluation processing of the radio link quality according to the detected RS, and may be adapted to the detection of the radio link that performs signal transmission using any signal transmission mode, for example, the detection of the radio link that uses the LBT-based signal transmission mode in the 5G application, and thus improve the reliability of the radio link detection.
