Description

Wireless link detection method 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 wireless (NR) systems, such as 5G applications, unlicensed spectrum may be employed, i.e., communication using NR technology over channels of unlicensed spectrum. In order for individual wireless communication systems using unlicensed spectrum to perform wireless communication to co-exist friendly over the spectrum, some countries or regions specify regulatory requirements that must be met using unlicensed spectrum. For example, in the european region, the communication device follows the principle of listen-before-talk (LBT), that is, the communication device needs to perform channel interception on the channel of the unlicensed spectrum before performing signal transmission on the channel of the unlicensed spectrum, and only when the channel interception result is that the channel is idle, the communication device can perform signal transmission; if the channel listening results in a busy channel, the communication device is unable to signal.

However, since the signal transmission mode based on the LBT principle is not completely dependent on the receiving end and the transmitting end of the signal, but also depends on the channel condition of the wireless link, for this new transmission mode, it is needed to provide a method for detecting the wireless link, so as to achieve the correct detection of the wireless link.

210. And in the specified evaluation time, if the detection condition of a Reference Signal (RS) detected by the terminal equipment meets the specified condition, the terminal equipment performs evaluation processing of the wireless link quality according to the detected RS.

In this way, if the detection condition of the RS detected by the terminal device meets the specified condition in the specified evaluation time, the terminal device can perform the evaluation processing of the radio link quality according to the detected RS, so that the terminal device can be suitable for the detection of the radio link adopting any signal transmission mode to perform signal transmission, for example, the detection of the radio link adopting the signal transmission mode based on the LBT principle in the 5G application, and the reliability of the radio link detection is improved.

In the invention, the terminal equipment can be configured with a plurality of RS resources for wireless link monitoring (Radio Link Monitoring, RLM) of the terminal. One RS resource refers to a group of RSs that perform periodic transmission on a specified time-frequency resource.

The terminal device may determine, based on the period of the RS resource and constraint information of the protocol, a specified evaluation time T required for the RS resource to perform radio link monitoring of the terminal device. The available RSs on the RS resources of the RLM can be used for evaluating the RS of the radio link quality within a specified evaluation time T, the number of these available RSs being the number of RSs that can be used for evaluating the radio link quality within the evaluation time T.

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

In the invention, in the appointed evaluation time, the terminal equipment can specifically judge the detection condition of the Reference Signal (RS) detected by the terminal equipment, and judge whether the detection condition meets the appointed condition.

If the specified condition is met, the terminal equipment can evaluate the quality of the wireless link according to the detected RS; if the specified condition is not satisfied, the terminal device may determine that the RS is not detected, or may further determine that the link quality of the detected wireless 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 plus noise ratio (Signal to Interference plus Noise Ratio, SINR) value, a reference signal received quality (Reference Signal Receiving Quality, RSRQ) value, a reference signal received power (Reference Signal Receiving Power, RSRP) value, and a received signal strength indication (Received Signal Strength Indication, RSSI) value, which 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 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 or k1 by N rounding results (such as an up rounding result or a down rounding result), where N1 is a positive integer, N1 is less than or equal to N, for example, n=10, n1=8, and k1 is less than or equal to 1, for example, n=10, k1=0.8; the N is the number of RSs that can be used to evaluate the quality of the wireless link in a specified evaluation time.

Further, the terminal device may further configure the N1 or k1 in advance, or may further obtain the N1 or k1 through a high-layer signaling or a system broadcast message, or may further obtain the N1 or k1 by adopting the two modes, which is not limited in this embodiment.

For example, the higher layer signaling may be a radio physical resource control (Radio Resource Control, RRC) message, specifically, the N1 or K1 may be carried by an information element (Information Element, IE) in the RRC message, where the RRC message may be an RRC message in the prior art, for example, an RRC connection reconfiguration (RRC CONNECTION RECONFIGURATION) message, etc., which is not limited in this embodiment, the N1 or K1 may be carried by expanding an IE of an existing RRC message, or the RRC message may also be an RRC message different from the existing RRC message in the prior art.

Or, for another example, the higher layer signaling may be a media access Control (Media Access Control, MAC) Element (CE) message, and in particular, the N1 or K1 may also be carried by adding a new MAC CE message.

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

Wherein the second threshold may be N2 or k2 by N rounding result (e.g., up rounding result or down rounding result, etc.), where N2 is a positive integer, N2 is less than or equal to N, e.g., n=10, n2=8, and k2 is less than or equal to 1, e.g., n=10, k2=0.8; the N is the number of RSs that can be used to evaluate the quality of the wireless link in a specified evaluation time.

Further, the terminal device may further configure the N2 or k2 in advance, or may acquire the N2 or k2 through a high-layer signaling or a system broadcast message, or may acquire the N2 or k2 by adopting the two modes, which is not limited in this embodiment.

For example, the higher layer signaling may be a radio physical resource control (Radio Resource Control, RRC) message, specifically, the N2 or K2 may be carried by an information element (Information Element, IE) in the RRC message, where the RRC message may be an RRC message in the prior art, for example, an RRC connection reconfiguration (RRC CONNECTION RECONFIGURATION) message, etc., which is not limited in this embodiment, the N2 or K2 may be carried by expanding an IE of an existing RRC message, or the RRC message may also be an RRC message different from the existing RRC message in the prior art.

Or, for another example, the higher layer signaling may be a media access Control (Media Access Control, MAC) Element (CE) message, and in particular, the N2 or K2 may also be carried by adding a new MAC CE message.

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

In a specific implementation process, in 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 an RS is smaller 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 and noise ratio (Signal to Interference plus Noise Ratio, SINR) value, a reference signal received quality (Reference Signal Receiving Quality, RSRQ) value, a reference signal received power (Reference Signal Receiving Power, RSRP) value, and a received signal strength indication (Received Signal Strength Indication, RSSI) value, which is not particularly limited in this embodiment.

In another specific implementation process, in the specified evaluation time, if the link quality of a 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 reflected 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.

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

For example, the third quality threshold is a BLER value; in 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 a radio link to which one RS reacts 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 an RS is smaller than the third measurement threshold, or if the BLER value of the radio link to which an RS is reacted is larger than the third quality threshold, the terminal device may determine that the RS is not detected.

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

Optionally, in one possible implementation manner of this embodiment, in 210, the terminal device may specifically determine the signal quality of the detected RS and the 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, so as to obtain the signal quality of the detected RSs, for example, power value average, etc.

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

In another specific implementation process, if the signal quality of the detected RS is smaller than the second measurement threshold under the condition that the specified condition is met, the terminal device may determine that the link quality of the detected wireless link is lower than the 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 satisfied, the terminal device may determine that the link quality of the detected wireless link is higher than or equal to the quality corresponding to the third quality threshold and is lower than the quality corresponding to the second quality threshold.

In another specific implementation process, if the signal quality of the detected RS is greater than or equal to a second measurement threshold and is lower than the first measurement threshold under the condition that the specified condition is satisfied, the terminal device may determine that the link quality of the detected wireless link is greater than or equal to the quality corresponding to the second quality threshold and is 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 meets the specified condition in the specified evaluation time, the terminal device may perform the evaluation processing of the radio link quality according to the detected RS, so as to be suitable for the detection of the radio link that uses any signal transmission mode to perform signal transmission, for example, the detection of the radio link that uses the signal transmission mode based on the LBT principle in the 5G application, thereby improving the reliability of the radio link detection.
