[0076] In the prior art, beam management usually consists of beam scanning, beam measurement, beam decision, reporting and indication, beam switching and beam recovery. In the downlink direction, the channel state information reference signal (CSI-RS, Channel State Information-Reference Signal) and / or the synchronization signal block (SSB, Synchronization Signal Block) are used for downlink beam management.

[0077] The base station sends reference signals in multiple candidate beams, and the terminal performs beam measurement and reporting on multiple candidate beams, so that the base station determines the beam used in subsequent data transmission based on the measurement results of the candidate beams; specifically, the terminal receives the reference signals sent through each candidate beam, estimates the quality of the received reference signal, and then feeds back the measurement results of one or more candidate beams with the highest signal quality to the base station side. For example, if beam N is a LOS path and other beams are NLOS paths, then beam N will be the beam with the best quality, and the terminal will feed back the measurement results of beam N to the base station; wherein the measurement results reported by the terminal do not distinguish between the signal quality of the LOS path and the signal quality of the NLOS path, that is, the measurement results of the candidate beams reported by the terminal do not distinguish between the signal quality of the LOS path and the signal quality of the NLOS path.

[0078] The communication and perception integration technology enables the communication system to have the ability to perceive and realize the perception of non-network targets. For example, the perception algorithm can be used to obtain the location information (including distance, angle, etc.) between the detection target and the base station. In the collaborative perception mode of communication and perception integration, the perception signal sent by the base station may be transmitted to the terminal via the NLOS path, such as Figure 1 The black part shows the NLOS path, and the perception signal transmitted via the NLOS path implies the information of the perception target; in the related art, the measurement results of the candidate beams reported by the terminal do not distinguish between the signal quality of the LOS path and the signal quality of the NLOS path, and the base station cannot know the signal quality of the NLOS path of the candidate beam, and cannot select the candidate beam with the best signal quality of the NLOS path to send the perception signal, which may result in poor quality of the perception signal received by the terminal, resulting in low accuracy and precision of the perception information of the perception target determined by the terminal based on the received perception signal, and may even cause the terminal to be unable to receive the perception signal transmitted via the NLOS path, and thus unable to obtain the perception information (position, speed, etc.) of the perception target; the perception target can be understood as the target object to be detected.

[0079] Based on this, in various embodiments of the present application, the network device sends first information to the terminal, and the first information is at least used to indicate the measurement configuration of the indirect NLOS path of the reference signal; the terminal receives the first information sent by the network device, and reports the measurement result to the network device according to the first information; wherein the measurement result is obtained according to the first information, including the measurement result of the NLOS path of the reference signal and / or the measurement result of the LOS path of the reference signal. In the above scheme, the network device can indicate the measurement configuration of the NLOS path of the reference signal to the terminal. The terminal measures the NLOS path of the reference signal according to the measurement configuration of the NLOS path of the reference signal, and reports the measurement result of the NLOS path of the reference signal and / or the measurement result of the LOS path of the reference signal, so that the network device can determine the beam suitable for sending the perception signal and / or the NLOS path of the reference signal in the subsequent perception service according to the measurement result of the NLOS path of the reference signal and / or the measurement result of the LOS path of the reference signal, so as to improve the signal quality of the perception signal, thereby enabling the terminal or network device to accurately determine whether there is a perception target and determine the perception information of the perception target according to the received perception signal, thereby improving the perception accuracy and perception precision.

[0080] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0081] The present application embodiment provides a measurement method, which is applied to a network device, wherein the network device includes a base station, such as Figure 2 As shown, the method includes:

[0082] Step 201: Send first information to a terminal.

[0083] The first information is at least used to indicate the measurement configuration of the NLOS path of the reference signal.

[0084] Here, the first information can be carried in radio resource control (RRC) signaling or RRC message, and the network device can activate the measurement configuration of the NLOS path of the reference signal through downlink control information (DCI) or media access control (MAC) control unit (CE, Control Element), namely MAC CE.

[0085] It should be noted that the first information can also be used to indicate the measurement configuration of the LOS path of the reference signal. The network device can send the first information based on the capability information of the terminal. For example, when the terminal supports the measurement of the NLOS path of the reference signal, the first information is sent; the capability information of the terminal can be pre-configured in the network device, or reported by the terminal, or obtained by the network device from the terminal. The network device can also directly send the first information without considering the capability of the terminal, and the terminal decides whether to perform the measurement of the NLOS path of the reference signal according to the terminal capability; for example, when the terminal supports the measurement of the NLOS path of the reference signal, the terminal measures the NLOS path of the reference signal according to the first information; when the terminal does not support the measurement of the NLOS path of the reference signal, the first information is ignored or discarded. Wherein, the reference signal is sent by the network device through a beam, a reference signal has at least one NLOS path, and a reference signal has only one LOS path.

[0086] It should be noted that, in a scenario where the terminal operates in the FR2 frequency band, the terminal needs to know which receiving direction is most appropriate for the NLOS path of the reference signal. In an embodiment of the present application, the network device sends a measurement configuration of the NLOS path of the reference signal to the terminal, so that the terminal can measure the measurement result of each NLOS path of each reference signal according to the NLOS path measurement configuration of the reference signal to determine the receiving direction of each NLOS path of each reference signal, so as to improve the communication performance of the terminal.

[0087] In order to obtain more accurate perception information and further improve perception accuracy, in one embodiment, the first information includes at least one of the following:

[0088] Second information, where the second information is used to instruct the terminal to report a measurement result of an NLOS path and / or a LOS path of a reference signal;

[0089] Reporting volume;

[0090] A first number, where the first number represents the number of reference signals that the terminal needs to report;

[0091] A second number, where the second number represents the number of NLOS paths that the terminal needs to report;

[0092] The third information is used to indicate the identifier of the terminal reporting the NLOS path.

[0093] In one embodiment, the reported amount includes at least one of the following:

[0094] RSRP of NLOS path;

[0095] SINR of the NLOS path;

[0096] RSRP of LOS path;

[0097] SINR of LOS path;

[0098] AOA of LOS path;

[0099] AOA of NLOS path;

[0100] A first speed, wherein the first speed represents a moving speed of the perceived target measured according to the NLOS path of the reference signal.

[0101] Here, the second information can be understood as the reporting type, and the reporting type can be represented by reportType, and the reporting type can be at least one of {NLOS, LOS, NLOS+LOS, LOS+NLOS}. Among them, when the reporting type is NLOS, the terminal only needs to report the measurement result of the NLOS path of the reference signal, or the terminal additionally reports the measurement result of the NLOS path of the reference signal while complying with the existing measurement configuration; the existing measurement configuration is also called a conventional measurement configuration. It should be noted that the measurement result of the NLOS path of the reference signal reflects the signal strength of the perception signal after being reflected by the perception target. Compared with the measurement result of the LOS path of the reference signal, or the average measurement result of the reference signal, the measurement result of the NLOS path of the reference signal can more accurately determine whether there is a perception target, and more accurately determine the perception information of the perception target, thereby improving the perception accuracy.

[0102] When the reporting quantity type is LOS, the terminal only performs measurement and reporting of the LOS path of the reference signal, or the terminal additionally reports the measurement result of the LOS path of the reference signal while complying with the existing measurement configuration.

[0103] When the reporting quantity type is (NLOS+LOS) or (LOS+NLOS), the terminal performs measurement reporting of the LOS path of the reference signal and the NLOS path, or the terminal additionally reports the measurement results of the LOS path of the reference signal and the NLOS path while complying with the existing measurement configuration.

[0104] The reporting quantity can be expressed as ReportQuantity, and the reporting quantity can also be understood as a measurement quantity; the reporting quantity can be used to indicate the reporting content of the NLOS path and / or LOS path for the reference signal. Among them, the reporting quantity may only include the reporting quantity or reporting content of the NLOS path of the reference signal, for example, cri-NLOS-RSRP, ssb-Index-NLOS-RSRP, cri-NLOS-SINR, ssb-Index-NLOS-SINR, etc. cri-NLOS-RSRP, represents the RSRP of the NLOS path of the CSI-RS; ssb-Index-NLOS-RSRP, represents the RSRP of the NLOS path of the SSB indexed or identified as Index; cri-NLOS-SINR, represents the SINR of the NLOS path of the CSI-RS; ssb-Index-NLOS-SINR, represents the SINR of the NLOS path of the SSB indexed or identified as Index.

[0105] The reported amount may also only include the reported amount or reported content of the LOS path of the reference signal, such as cri-LOS-RSRP, ssb-Index-LOS-RSRP, cri-LOS-SINR, ssb-Index-LOS-SINR, etc. cri-LOS-RSRP represents the RSRP of the LOS path of the CSI-RS; ssb-Index-LOS-RSRP represents the RSRP of the LOS path of the SSB indexed or identified as Index; cri-LOS-SINR represents the SINR of the LOS path of the CSI-RS; ssb-Index-LOS-SINR represents the SINR of the LOS path of the SSB indexed or identified as Index.

[0106] The reported amount may also include the reported amount or reported content of the NLOS path and LOS path of the reference signal, for example, cri-LOSNLOS-RSRP, ssb-Index-LOSNLOS-RSRP, cri-LOSNLOS-SINR, ssb-Index-LOSNLOS-SINR, etc. cri-LOSNLOS-RSRP represents the RSRP of the NLOS path of the CSI-RS and the RSRP of the LOS path of the CSI-RS; ssb-Index-LOSNLOS-RSRP represents the RSRP of the NLOS path and the RSRP of the LOS path of the SSB indexed or identified as Index; cri-LOSNLOS-SINR represents the SINR of the NLOS path of the CSI-RS and the SINR of the LOS path of the CSI-RS; ssb-Index-LOS-SINR represents the SINR of the NLOS path of the SSB indexed or identified as Index and the SINR of the LOS path.

[0107] The first quantity can be recorded as nrofReportedRS, and the first quantity is used to indicate that the terminal reports the measurement results of the first number of reference signals with better signal quality. For example, when the first information includes the first quantity, the first quantity is N, and the reporting quantity type is NLOS or (NLOS+LOS), it indicates that the terminal needs to report the index of the reference signal with better signal quality of N NLOS paths and / or the corresponding measurement results; when the first information does not include the first quantity, it indicates that the terminal only needs to report the index of the reference signal with the best signal quality of 1 NLOS path and / or the corresponding measurement results. For another example, when the first information includes the first quantity, the first quantity is N, and the reporting quantity type is LOS or (LOS+NLOS), it indicates that the terminal needs to report the index of the reference signal with better signal quality of N LOS paths and / or the corresponding measurement results; when the first information does not include the first quantity, it indicates that the terminal only needs to report the index of the reference signal with the best signal quality of 1 LOS path and / or the corresponding measurement results.

[0108] The second number may be recorded as nrofNLOS, and the second number is used to indicate that the terminal reports the measurement results of the second number of NLOS paths with better signal quality for each reference signal. For example, when the first information includes the second number and the second number is M, the second number is used to indicate that the terminal reports the measurement results of M NLOS paths with better signal quality for each reference signal; when the first information does not include the second number, it indicates that the terminal only needs to report the measurement result of one NLOS path with the best signal quality for each reference signal.

[0109] The NLOS AOA included in the reported amount is used to instruct the terminal to report the incident angle obtained by measuring the NLOS path of the reference signal. The LOS AOA included in the reported amount is used to instruct the terminal to report the incident angle obtained by measuring the LOS path of the reference signal. The first speed can be expressed as NLOS speed, which is used to instruct the terminal to report the moving speed of the perceived target obtained by measuring the NLOS path of the reference signal; wherein, the terminal can measure the moving speed of the perceived target according to the perception signal sent by the network device in the direction of the NLOS path of the reference signal. It should be noted that LOS AOA and / or NLOS AOA can be used by the network device to determine the position of the terminal; the difference between the measurement result of the NLOS path of the reference signal and the measurement result of the LOS path of the reference signal can be used by the network device to accurately determine whether there is a perceived target at present, and in the case of a perceived target, it can also accurately determine the position information, reflection loss, speed, etc. of the perceived target based on the measurement result of the NLOS path of the reference signal, thereby improving the perception accuracy and perception precision. In the perception process, the measurement result of the NLOS path of the reference signal can be understood as the measurement result of the perception signal transmitted via the NLOS path of the reference signal, and the measurement result of the LOS path of the reference signal can be understood as the measurement result of the perception signal transmitted via the LOS path of the reference signal.

[0110] The third information is used to indicate the identifier of the NLOS path reported by the terminal, which can be represented by NLosID. ​​The identifier of the NLOS path can also be understood as the index of the NLOS path. The third information is an optional parameter. For example, when the first information does not include the second number, or the second number is 1, the first information may not include the third information; when the second number in the first information is greater than or equal to 2, the first information includes the third information.

[0111] It should be noted that the terminal feeds back the index or identifier of the reference signal and the measurement result of the NLOS path of the reference signal to the network device, so that the network device can determine the direction of the perception target according to the information fed back by the terminal, and determine the beam suitable for sending the perception signal and / or the NLOS path of the reference signal in the subsequent perception service. In addition, the network device can distinguish environmental objects and perception targets based on the measurement results of the NLOS paths of multiple reference signals fed back by multiple terminals within a period of time and the measurement results of multiple NLOS paths of a single reference signal, and use the most appropriate sending direction or sending beam to send the perception signal in the subsequent perception service. Among them, the reference signal is sent through a beam, and the network device can know the correspondence between the reference signal and the beam. After obtaining the measurement result of the NLOS path of the reference signal, the network device can determine the reference signal corresponding to the LOS path with better signal quality, and use the beam for sending the perception signal according to the correspondence between the reference signal and the beam.

[0112] In order to save the signaling overhead of the network device, the network device can decide whether to send the first information to the terminal according to the capability information of the terminal. Therefore, before the network device sends the first information, it is necessary to obtain the capability information of the terminal. Based on this, in one embodiment, the method further includes:

[0113] receiving capability information reported by the terminal; wherein,

[0114] The capability information is used to indicate at least one of the following capabilities:

[0115] Whether the terminal supports the measurement of the NLOS path of the reference signal;

[0116] The number of NLOS paths that the terminal supports measuring;

[0117] Whether the terminal supports the measurement of the LOS path of the reference signal.

[0118] Here, in the case where the capability information of the terminal indicates that the terminal supports the measurement of the NLOS path of the reference signal, the capability information of the terminal may also indicate the number of NLOS paths that the terminal supports measuring.

[0119] In order to save the signaling overhead of the network device and reduce the data processing amount of the terminal to save the resources of the terminal, in one embodiment, the first information is sent when at least one of the following is met:

[0120] The capability information indicates that the terminal supports measurement of the NLOS path of the reference signal;

[0121] The capability information indicates that the terminal supports the measurement of the LOS path of the reference signal.

[0122] Here, the network device decides whether to send the first information to the terminal according to the capability information of the terminal. When the terminal supports the measurement of the NLOS path of the reference signal, and / or the terminal supports the measurement of the LOS path of the reference signal, the network device sends the first information to the terminal. Wherein, when the capability information of the terminal indicates that the terminal supports the measurement of the NLOS path of the reference signal, the first information is used to indicate the measurement configuration of the NLOS path of the reference signal; when the capability information of the terminal indicates that the terminal supports the measurement of the LOS path of the reference signal, the first information is used to indicate the measurement configuration of the LOS path of the reference signal. The network device can also configure the second number contained in the first information according to the number of NLOS paths supported by the terminal for measurement, and the second number is less than or equal to the number of NLOS paths supported by the terminal for measurement.

[0123] That is to say, the first information sent by the network device to the terminal is adapted to the terminal capability. When the capability information of the terminal indicates that the terminal supports the measurement of the NLOS and / or LOS path of a certain reference signal, the first information indicates the measurement configuration of the NLOS and / or LOS path of the reference signal; for example, the capability information of the terminal indicates that the terminal supports the measurement of the NLOS path and / or LOS path based on SSB / CSI-RS / SSB+CSI-RS, and the first information is used to indicate the measurement configuration of the NLOS path and / or LOS path based on SSB / CSI-RS / SSB+CSI-RS.

[0124] Correspondingly, the embodiment of the present application also provides a measurement method, which is applied to a terminal, such as Figure 3 As shown, the method includes:

[0125] Step 301: Receive first information sent by a network device.

[0126] The first information is at least used to indicate the measurement configuration of the NLOS path of the reference signal.

[0127] Step 302: Report the measurement result to the network device according to the first information.

[0128] Here, the terminal measures at least the NLOS path of the reference signal based on the received first information to obtain the measurement result of the NLOS path of the reference signal, and reports the measurement result of the NLOS path of the reference signal that meets the reporting conditions to the network device; the terminal can also measure the LOS path of the reference signal to obtain the measurement result of the LOS path of the reference signal, and report the measurement result of the LOS path of the reference signal that meets the reporting conditions to the network device.

[0129] In actual application, the terminal can report the measurement results of the NLOS path of one or more reference signals with better signal quality to the network device, so that the network device can determine the beam suitable for sending the perception signal and / or the NLOS path of the reference signal based on the measurement results with better signal quality.

[0130] In order to save the signaling overhead of the network device sending the first information and ensure that the first information sent by the network device to the terminal is compatible with the terminal capability, in one embodiment, before receiving the first information sent by the network device, the method further includes:

[0131] Sending capability information to the network device; wherein,

[0132] The capability information is used to indicate at least one of the following capabilities:

[0133] Whether the terminal supports the measurement of the NLOS path of the reference signal;

[0134] The number of NLOS paths that the terminal supports measuring;

[0135] Whether the terminal supports the measurement of the LOS path of the reference signal.

[0136] Here, the capability information may include at least one of SSB-NLOS-meas, CSI-RS-NLOS-meas, and SSB-CSI-RS-NLOS-meas. Among them, SSB-NLOS-meas indicates support for measurement of NLOS path based on SBB; CSI-RS-NLOS-meas indicates support for measurement of NLOS path based on CSI-RS; SSB-CSI-RS-NLOS-meas indicates support for measurement of NLOS path based on SSB and CSI-RS.

[0137] When the capability information includes SSB-NLOS-meas, the capability information may also include NrofSSB-NLOS-meas=m, NrofSSB-NLOS-meas=m indicates that the terminal supports the measurement of NLOS paths based on SBB, and the number of NLOS paths supported for measurement is m; when the capability information includes CSI-RS-NLOS-meas, the capability information may also include NrofCSI-RS-NLOS-meas=n, NrofCSI-RS-NLOS-meas=n indicates that the terminal supports the measurement of NLOS paths based on CSI-RS, and the number of NLOS paths supported for measurement is n; when the capability information includes SSB-CSI-RS-NLOS-meas=k, the capability information may also include NrofSSB-CSI-RS-NLOS-meas=k, indicating that the terminal supports the measurement of NLOS paths based on SBB and CSI-RS, and the number of NLOS paths supported for measurement is k.

[0138] In one embodiment, the first information includes at least one of the following:

[0139] Second information, where the second information is used to instruct the terminal to report a measurement result of an NLOS path and / or a LOS path of a reference signal;

[0140] Reporting volume;

[0141] A first number, where the first number represents the number of reference signals that the terminal needs to report;

[0142] A second number, where the second number represents the number of NLOS paths that the terminal needs to report;

[0143] The third information is used to indicate the identifier of the terminal reporting the NLOS path.

[0144] In order to further improve the perception accuracy, in one embodiment, the reported amount includes at least one of the following:

[0145] RSRP of NLOS path;

[0146] SINR of the NLOS path;

[0147] RSRP of LOS path;

[0148] SINR of LOS path;

[0149] AOA of LOS path;

[0150] AOA of NLOS path;

[0151] A first speed, wherein the first speed represents a moving speed of the perceived target measured according to the NLOS path of the reference signal.

[0152] Here, when the number of reported quantities is greater than or equal to 2, the terminal can use the set differential reported quantity to report at least two reported quantities. Specifically, the terminal can first report the value of the first reported quantity, and then report at least one numerical value, such as a binary numerical value, based on the value of the first reported quantity and the set differential reported quantity, so that the network device can determine the value of at least one second reported quantity based on the first reported quantity and at least one numerical value. The first reported quantity is any reported quantity, and the second reported quantity represents any reported quantity other than the first reported quantity. The network device calculates a second reported quantity based on the first reported quantity and a numerical value. Among them, the reported numerical value = (first reported quantity-second reported quantity) / set differential reported quantity. For example, the reported quantity includes a first reported quantity and a second reported quantity, the first reported quantity is the RSRP of the LOS path, and the second reported quantity is the RSRP of the NLOS path. When the set differential reporting amount is 3dB, the RSRP of the LOS path is 6dB, and the RSRP of the NLOS path is 0dB, the terminal can first report the RSRP of the LOS path as 6dB; according to the difference between the first reporting amount and the second reporting amount, and the set differential reporting amount, report the first value to the network device, the first value = (6-0) / 3 = 2. Among them, the terminal can report the decimal number 2 or the binary number 10 to the network device.

[0153] When the network device receives the first reporting amount, it can calculate the second reporting amount according to the following formula: second reporting amount = first reporting amount - reported value × set differential reporting amount.

[0154] It should be noted that, in actual applications, the terminal may also use multiple bits to report multiple values, and the value of the set differential reporting amount may be an integer greater than 1. This can make the value reported according to the set differential reporting amount smaller, thereby reducing the number of bits occupied by the reported value and reducing the overhead of differential reporting.

[0155] The present application is further described in detail below in conjunction with application examples.

[0156] Application Example 1: Measuring the signal quality of the NLOS path of SSB

[0157] Step 1: The terminal reports its capability information to the network device. The capability information includes SSB-NLOS-meas, indicating that the terminal supports the measurement of the NLOS path based on SSB.

[0158] Step 2: The network device sends first information to the terminal according to the capability information reported by the terminal. The first information includes:

[0160] Report quantity (ReportQuantity), the reported quantity includes ssb-Index-NLOS-RSRP;

[0161] The second number is 2, which is used to instruct the terminal to report the measurement results of two NLOS paths for each SSB;

[0162] The third information is used to instruct the terminal to report the identifier of the NLOS path.

[0163] Step 3: The terminal receives the first information, measures the NLOS path of the SSB according to the first information, and obtains the measurement result of the NLOS path of the SSB.

[0164] The measurement result of the NLOS path of SSB includes ssb-Index-NLOS-RSRP.

[0165] Step 4: For each SSB, the terminal reports the measurement results of the two NLOS paths with the best signal quality and the corresponding SSB identifiers to the network device.

[0166] Here, for each SSB, the terminal can report the RSRP and NLOS path identifiers of the two NLOS paths with the best signal quality to the network device. For example, the terminal reports the following information to the network device:

[0167] ssb-Index-NLOS-RSRP: NLosID=3, RSRP=4dB; NLosID=1, RSRP=1dB.

[0168] ssb-Index-NLOS-RSRP, represents the RSRP of the NLOS path of the SSB identified as Index; NLosID=3, RSRP=4dB, represents that the identifier of the NLOS path of the SSB is 3, and the RSRP of the NLOS path identified as 3 is 4dB; NLosID=1, RSRP=1dB, represents that the identifier of the NLOS path of the SSB is 1, and the RSRP of the NLOS path of the SSB is 1dB.

[0169] After the network device obtains the measurement results of the two NLOS paths with better signal quality of each SSB, it can determine the NLOS path of the SSB that is suitable for sending the perception signal in the subsequent perception service based on the measurement results of the NLOS path of the SSB.

[0173] Second information (reportType is NLOS), the second information is used to instruct the terminal to report the measurement result of the NLOS path of the CSI-RS;

[0174] Report quantity (ReportQuantity), the reported quantity includes cri-NLOS-SINR;

[0175] The second number is 2, which is used to instruct the terminal to report the measurement results of two NLOS paths for each CSI-RS;

[0176] The third information is used to instruct the terminal to report the identifier of the NLOS path.

[0177] Step 3: The terminal receives the first information, measures the NLOS path of the CSI-RS according to the first information, and obtains a measurement result of the NLOS path of the CSI-RS.

[0178] The measurement result of the NLOS path of the CSI-RS includes cri-NLOS-SINR.

[0179] Step 4: For each CSI-RS, the terminal reports the measurement results of the two NLOS paths with the best signal quality and the corresponding CSI-RS identifiers to the network device.

[0180] Here, for each CSI-RS, the terminal can report to the network device the SINR of the two NLOS paths with the best signal quality, the identifier of the NLOS path, and the identifier of the CSI-RS corresponding to the NLOS path. For example, the terminal reports the following information to the network device:

[0181] cri-NLOS-SINR: CSI-RS report indicator=3; NLosID=1, SINR=2dB;

[0182] NLosID=2, SINR=0dB.

[0183] Among them, CSI-RS report indicator = 3, indicating that the CSI-RS with the best signal quality of the NLOS path is identified as 3; NLosID = 1, SINR = 2dB, indicating that the SINR of the NLOS path identified as 1 is 2dB; SINR = 2dB; NLosID = 2, SINR = 0dB, indicating that the SINR of the NLOS path identified as 2 is 0dB.
