It should be noted that the channel measurement signal corresponding to the CMR set and the interference measurement signal corresponding to the IMR set may each include one or more SSBs and/or one or more CSI-RSs, and the difference between the two signals is that: the channel measurement signal is used for simulating a signal carrying user data, and the interference measurement signal is used for simulating other signals which interfere with the signal carrying user data, including but not limited to signals of other networks, signals for carrying other user data, and the like.

In the embodiment of the present application, for convenience of description, CSI-RS # n may be used to denote a CSI-RS channel measurement resource or a CSI-RS interference measurement resource of resource number n. Similarly, SSB # n may be used to indicate an SSB channel measurement resource with resource number n or an SSB interference measurement resource.

Illustratively, in the embodiment of the present application, the beam scanning manner is for the CMR set, and existing implementations may be adopted, such as using a CMR repetition (CMR repetition) information element to indicate. For example, when the CMR repetition cell value is "ON", the beam scanning manner of the CMR set is: the network device transmits each CMR in the CMR set using a fixed transmit beam, and the terminal device should receive each CMR in the CMR set using a different receive beam, so as to determine an optimal receive beam for the terminal device. For another example, when the CMR repetition cell value is "OFF", the beam scanning manner of the CMR set is: the network device transmits each CMR in the CMR set by using a fixed transmission beam, and the terminal device receives each CMR in the CMR set by using a fixed receiving beam, so as to determine an optimal transmission beam of the network device. The term "optimal" refers to a reception beam or a transmission beam that satisfies one or more of the following conditions in the certain beam scanning system: the terminal device receives the strongest signal, such as the maximum value of Reference Signal Receiving Power (RSRP); alternatively, the terminal device may receive the best signal quality, such as the highest Reference Signal Receiving Quality (RSRQ).

In an actual communication scenario, the source, direction, intensity, and the like of the interference signal generally vary in the time domain and the space domain, and it is not necessary to consider a case where the beam scanning method of the IMR set is a fixed interference transmission beam. The reason for this is that: when the beam scanning mode of the IMR set is configured to be ON, the method can be used in a scenario in which an interference beam is fixed and a service beam is selected in the CMR set, and then the base station knows information of the interference beam, such as an IMR index, and the terminal device does not need to feed back the IMR index to the base station. Therefore, in the embodiment of the present application, the beam scanning manner of the IMR set may be configured as: the transmit beams of the IMR set are not fixed, as the value of the IMR repetition (IMR repetition) information element may be configured to be "OFF". Of course, it is also possible to not configure, i.e., default IMR repeat cell value is "OFF". For a specific implementation of the beam scanning manner, reference may be made to the following description in S302, and details are not repeated here.

It should be noted that, in order to save configuration resources, the CMR duplication cell and the IMR duplication cell may share the same duplication cell field (duplication field) for indication. For example, if the repetition cell field is configured to be ON, it indicates that the CMR repetition cell is configured to be ON, i.e., the beam scanning manner of the CMR set is the fixed interference transmission beam, and the IMR repetition cell is configured to be OFF, i.e., the beam scanning manner of the IMR set is the unfixed interference transmission beam.

Illustratively, the network device may transmit the measurement configuration information to the terminal device on a Downlink (DL) in any one of Radio Resource Control (RRC) signaling, medium access control-control element (MAC-CE) signaling, Downlink Control Information (DCI) signaling, broadcast (broadcast), System Information Block (SIB), and the like.

S302, the network equipment sends signals to the terminal equipment on the CMR set and the IMR set. Accordingly, the terminal device receives and measures signals from the network device on the CMR set and the IMR set.

Illustratively, the network device sends a signal to the terminal device on each of the CMRs in the set of CMRs, and on each of the IMRs in the set of IMRs. Accordingly, the terminal device receives and measures signals from the network device at each of the CMRs in the set of CMRs, and at each of the IMRs in the set of IMRs.

At present, according to the configuration in step S301, if the network device and the terminal device complete interference measurement by traversing the transmit beam and the receive beam, a simplest method for measuring an interference beam is as follows: the terminal device combines each resource in the CMR set with each resource in the IMR set and measures each CMR-IMR combination with each receive beam of the terminal device. The problem with this approach is that: the complexity is very high and the workload is large. Specifically, assuming that the network device configures N _ CMR resources and N _ IMR resources, and the terminal device has M _ RX receive beams, the terminal device needs to perform N _ CMR × N _ IMR × M _ RX measurements to obtain N _ CMR × N _ IMR _ M _ RX different L1-SINR, and then selects an optimal CMR-IMR combination and reports the optimal CMR-IMR combination to the network device. Therefore, the method avoids excessively complicated measurement, reduces the measurement workload, improves the measurement efficiency, and is one of the technical problems to be solved by the application.

Exemplarily, fig. 4 illustrates a scene schematic diagram of a beam scanning manner provided in an embodiment of the present application. As shown in fig. 4, the CMR set includes CSI-RS1-CSI-RS4, and the beam scanning mode of the CMR set is as follows: and fixing the transmitting beam, wherein the beam scanning mode is used for training the receiving beam by the terminal equipment. For example, a repetition cell (CMR repetition) in the CMR set configuration parameters may be configured to be ON. The fixed transmission beam means that the network device transmits CSI-RS1-CSI-RS4 in the CMR set by using the same transmission beam, for example, transmission beam 1. The IMR set comprises CSI-RS5-CSI-RS8, and is used for simulating interference generated by signals transmitted by other transmission beams of the network equipment on signals transmitted by the transmission beams corresponding to the CMR set on the terminal equipment side. In the interference measurement scenario shown in fig. 4, the interference measurement method may specifically include the following steps:

step one, the network equipment uses the same transmission beam to transmit the signal in the CMR set. Accordingly, the terminal device traverses the reception beams and selects an optimal reception beam.

Specifically, the network device may transmit all CSI-RSs in the CMR set on the same transmission beam in a preset order. Accordingly, the terminal device can measure the received signal using each reception beam, and select the reception beam whose received signal strength is the greatest as the optimal reception beam. The signal strength may be L1-RSRP.

And step two, the network equipment uses different transmitting beams to transmit signals in the IMR set. Accordingly, the terminal device receives and measures the signal strength in the IMR set using the optimal receive beam.

Specifically, the terminal device may receive and measure the signal strength of CSI-RS5-CSI-RS8 in the IMR set, such as L1-RSRP of CSI-RS5-CSI-RS8, using the optimal receive beam.

And step three, the terminal equipment calculates the signal to interference plus noise ratio (such as L1-SINR) corresponding to each signal in the CMR set according to the signal strength in the CMR set received by the terminal equipment and the signal strength in the IMR set.

Specifically, in view of the beam scanning manner in the IMR set configuration parameters, such as that IMR repetition cell (IMR repetition) is configured to be OFF or not configured, the IMR set may be used for the terminal device to evaluate the interference condition of the transmission beams of other network devices received on the reception beam with the strongest L1-RSRP, that is, to calculate the L1-SINR by using the CSI-RS2 and the CSI-RS5-CSI-RS 8.

In the implementation manner, in a scenario where the beam scanning manner of the CMR set is a fixed transmission beam, the network device needs to transmit the signal in the CMR set first, and after the terminal device determines the optimal reception beam according to the reception signal in the CMR set, the network device transmits the signal in the IMR set. Accordingly, the terminal device traverses the receive beam and determines the optimal receive beam, and then the terminal device uses the optimal receive beam to measure the signals in the IMR set, that is, the transmit sequence of the CMR set needs to be before the transmit sequence of the IMR set, and the timing advance depends on the processing duration of the terminal device traversing the receive beam and determining the optimal receive beam. Therefore, optionally, the network device further needs to transmit a time advance between the CMR set and the IMR set to the terminal device. For example, the timing advance may be configured directly by the network device, or may be configured after being determined according to the terminal capability level reported by the terminal device, which is not limited in this embodiment of the present application.

In another possible implementation manner, the network device may also simultaneously transmit one signal in the CMR set and one signal in the IMR set, so that the terminal device determines the optimal receiving beam according to the signal quality between the CMR signal and the IMR signal, such as L1_ SINR. Accordingly, the terminal device may measure the signal strength of the received CMR signal and the signal strength of the IMR signal using each reception beam, then calculate L1_ SINR corresponding to each reception beam according to the signal strengths, and select the reception beam with the largest L1_ SINR value as the optimal reception beam. And then, after the terminal equipment determines the optimal receiving beam, the network equipment sends other CMR signals in the CMR set and other IMR signals in the IMR set. Accordingly, the terminal device calculates L1_ SINR according to the signal strength of the other CMR signals in the received CMR set and the signal strength of the other IMR signals in the IMR set.

Exemplarily, fig. 5 to fig. 7 respectively show 3 scene diagrams of another beam scanning manner provided by the embodiment of the present application. As shown in fig. 5-7, the CMR set includes CSI-RS1-CSI-RS4, and the beam scanning mode of the CMR set is: the transmission beam is not fixed, and the beam scanning mode is used for the network device to train the transmission beam. For example, a duplicate cell (CMR repetition) in the CMR set configuration parameters may be configured to be OFF. The unfixed transmission beam refers to a reception beam of the fixed terminal device, and the reception network device receives CSI-RS1 to CSI-RS4 in the CMR set transmitted by using different transmission beams. The interference measurement method in the second beam interference measurement scenario is described in detail below by taking the interference measurement method shown in fig. 5 as an example. Specifically, the method may comprise the steps of:

step 1, the network equipment uses different transmitting beams to transmit signals in the CMR set. Accordingly, the terminal device uses the same receiving beam to respectively receive and measure signals in the CMR set transmitted by the network device by using different transmitting beams.

Illustratively, the terminal device may use the receiving beams of the same CMR configured by the network device to respectively receive and measure the signal strengths of CSI-RS1 to CSI-RS4 in the CMR set transmitted by the network device on the transmitting beams 1 to 4.

And 2, the network equipment transmits the signals in the IMR set by using different transmitting beams. Accordingly, the terminal device uses the same receiving beam to respectively receive and measure signals in the IMR set transmitted by the network device by using different transmitting beams.

Illustratively, the terminal device may receive and measure the signal strengths of CSI-RS5 through CSI-RS8 in the set of IMRs transmitted by the network device on transmission beams 1 through 4, respectively, using the reception beam of one IMR configured by the network device.

It should be noted that the same CMR receive beam may be configured by a network device, or may be selected by a terminal device, and the CMR receive beam and the IMR receive beam may be the same receive beam or different receive beams, which is not limited in this embodiment of the present application.

And 3, the terminal equipment calculates the signal to interference plus noise ratio (such as L1-SINR) corresponding to each signal in the CMR set according to the signal strength in the CMR set received by the terminal equipment and the signal strength in the IMR set.

Specifically, in view of the beam scanning manner in the IMR set configuration parameters, such as that an IMR repetition cell (IMR repetition) is configured to be OFF or not configured, the IMR set may be used for the terminal device to evaluate the interference condition of other transmission beams transmitted by the network device and received on the reception beam with the strongest L1-RSRP, such as calculating L1-SINR by using CSI-RS2-CSI-R4 and CSI-RS5-CSI-RS 8. The specific calculation method may refer to the existing implementation manner, and is not described herein again.

It should be noted that, since the beam scanning manner of the CMR set is not a fixed transmission beam, the method can be used for the network device to traverse the transmission beam and select an optimal transmission beam, and the transmission order of the CMR set and the IMR set has no influence on this purpose. Therefore, the embodiment of the application does not need to limit the sequence of sending the CMR set and the IMR set by the network device. That is, step 2 may be performed after step 1 is performed, that is, all signals in the CMR set are transmitted first and all signals in the IMR set are transmitted again as shown in fig. 5, or may be performed before step 1 is performed, that is, all signals in the IMR set are transmitted first and all signals in the CMR set are transmitted again as shown in fig. 6, or step 2 and step 1 may be performed alternately, that is, signals in the CMR set and signals in the IMR set are transmitted alternately as shown in fig. 7.

After the above steps one to three are performed, or the above steps 1 to 3 are performed, the terminal device may determine the content of the measurement report according to the beam scanning mode and the report amount, and report the content to the network device, that is, perform S303 to S304.

And S303, the terminal equipment determines the content of the measurement report according to the beam scanning mode and/or the report quantity.

In one possible design approach, if the beam scanning approach is: fixing the sending beam of the CMR set, wherein the reporting quantity comprises: CMR index, IMR index and signal to interference plus noise ratio, SINR, the measurement report includes IMR index and SINR and does not include CMR index.

For example, for the first beam measurement scenario shown in fig. 4, the beam scanning manner is to fix the transmission beams of the CMR set, that is, the network device already knows that all CMRs in the CMR set correspond to the same transmission beam. Therefore, even if the network device requires the terminal device to report the CMR index, if the configured reporting amount includes the CMR index, the terminal device does not need to report the CMR index, so that the reporting data amount can be reduced, and the reporting overhead can be saved.

It should be understood that, for the beam measurement scenario two shown in fig. 5 to fig. 7, the beam scanning mode is a transmission beam of an unfixed CMR set, and at this time, the network device does not know the transmission beam selected by the terminal device, and at this time, the terminal device is generally required to report all contents required to be reported by the report quantity, for example, report one or more sets of measurement results including the CMR index, the IMR index, and the SINR.

For example, for the beam measurement scenario two shown in fig. 5 to fig. 7, if the L1-SINR value reported by the terminal device is smaller, which indicates that the interference is larger, the terminal device may continue to report the IMR index in the next report. The next reporting may be reporting triggered by the network device alone, or reporting the IMR index by the terminal device in the periodic reporting using the next periodic reporting. That is, the L1-SINR and the IMR index can be reported in two steps according to the L1-SINR value. It is easy to understand that if the L1-SINR value is large, it indicates that the interference is small, and the IMR index does not need to be reported, so that the amount of data reported can be further reduced, and the reporting overhead can be reduced.

In one possible design method, if the reported quantity includes: CMR index, IMR index and signal to interference plus noise ratio, SINR, the measurement report includes either IMR index or SINR.

Alternatively, in another possible design method, if the beam scanning manner is: fixing the sending beam of the CMR set, wherein the reporting quantity comprises: one of the CMR index and the IMR index, and the signal to interference noise ratio SINR, the measurement report includes the IMR index or the SINR.

Optionally, the measurement report includes an IMR index or an SINR, and may include one of the following: if the SINR is greater than the first SINR threshold, the measurement report includes the SINR and does not include the IMR index. Alternatively, if the SINR is less than the second SINR threshold, the measurement report includes the IMR index and does not include the SINR. The first SINR threshold and the second SINR threshold may be the same value or different values, which is not limited in this embodiment of the present application.

Further, the measurement report may further include first indication information. The first indication information is used for indicating that the measurement report comprises an IMR index and does not comprise an SINR; or, the first indication information is used to indicate that the measurement report includes the SINR and does not include the IMR index.

Exemplarily, as shown in fig. 4, when the SINR is greater than the first SINR threshold, it is illustrated that the interference is weak, and an interfering beam does not need to be avoided, so that an IMR index does not need to be reported, and the SINR may be used for further fine-tuning the transmission scheme by the network device, such as adjusting the transmission power, the modulation and coding scheme, and so on, so that the SINR needs to be reported. When the SINR is smaller than the fourth SINR threshold, it indicates that the interference is strong at this time, and an interference beam needs to be avoided, so that the IMR index needs to be reported. After avoiding the interference, if the SINR is greater than the first SINR threshold, the terminal device may continue to report the SINR in the next report. The next reporting may be reporting triggered by the network device alone, or reporting the IMR index by the terminal device in the periodic reporting using the next periodic reporting.

In another possible design method, if the reported quantity includes: one of the CMR index and the IMR index, and the signal to interference and noise ratio, SINR, the measurement report includes one of the CMR index and the IMR index, and the SINR.

The third SINR threshold and the fourth SINR threshold may be the same value or different values, which is not limited in this embodiment of the application.

Optionally, the beam scanning manner may be: the transmit beams of the CMR set are fixed. Or, optionally, the beam scanning manner may also be: the transmit beams of the CMR set are not fixed.

For example, as shown in any one of fig. 5 to 7, when the SINR is greater than the third SINR threshold, it may be considered that a serving beam corresponding to the CMR index is relatively weak to be interfered by all interfering beams, and there is no need to avoid any interfering beam, so that the CMR index that can be used as the serving beam needs to be reported, but the IMR index does not need to be reported. When the SINR is smaller than the fourth SINR threshold, it may be considered that the interference beam corresponding to the IMR index has strong interference to all service beams and needs to be avoided, so that the IMR index needs to be reported, but the CMR index does not need to be reported.

It should be noted that the above-mentioned various alternatives for determining the content of the measurement report may be used alone or in combination, and the embodiments of the present application are not limited thereto. For example, when it is determined that the measurement report includes the IMR index and/or the SINR according to the beam scanning manner, the measurement report may be selected from the IMR index and the SINR according to a comparison result between the measurement value of the SINR and the first SINR threshold and/or the second SINR threshold, and then reported. For another example, when it is determined from the report amount that the measurement report includes the CMR index and/or the IMR index, the measurement report may be selected from the CMR index and the IMR index and reported according to a comparison result between the SINR measurement value and the third SINR threshold value and/or the fourth SINR threshold value.

In one possible design approach, if the beam scanning approach is: the transmit beam of the CMR set is fixed, then the measurement report does not include the CMR index. That is, regardless of how the reported quantity is configured and the measurement result is, the beam scanning method is: under the condition of fixing the transmission beam of the CMR set, the terminal equipment does not need to report the CMR index in view of the fact that the network equipment already knows the specific information of the transmission beam.

In another possible design method, if the reported quantity includes: one or more of IMR index and signal to interference and noise ratio, SINR, the measurement report includes one of IMR index and SINR.

Further, the measurement report may further include first indication information. The first indication information is used for indicating that the measurement report includes an IMR index, or the first indication information is used for indicating that the measurement report includes an SINR.

In another possible design method, if the reporting amount includes: one or more of a CMR index and an IMR index, the measurement report includes one of the CMR index and the IMR.

Optionally, the measurement report includes one of a CMR index and an IMR index, and may include: if the signal to interference plus noise ratio SINR is greater than the third SINR threshold, the measurement report includes the CMR index and does not include the IMR index. Alternatively, if the signal to interference plus noise ratio SINR is less than the fourth SINR threshold, then the measurement report includes an IMR index and does not include a CMR index.

S304, the terminal device sends a measurement report to the network device. Accordingly, the network device receives the measurement report from the terminal device.

Illustratively, the terminal device may send the CSI measurement report to the network device on an Uplink (UL) through a Physical Uplink Shared Channel (PUSCH).

Exemplarily, table 1 is an example one of CSI measurement reports. As shown in table 1, if the reported amounts include: CMR index, IMR index, and signal to interference plus noise ratio, SINR, the CSI measurement report may include: CMR index, IMR index and signal to interference plus noise ratio SINR.

It should be noted that the CSI measurement report shown in table 1 may include one or more sets of measurement results, such as two sets of measurement results with measurement result indexes 0 and 1 in table 1, where each set of measurement results includes one CMR index, one IMR index, and one L1-SINR.

TABLE 1

The bit length (bitwidth) of the CMR index is ceil { Log2(N _ CMR) }, the bit length (bitwidth) of the IMR index is ceil { Log2(N _ IMR) }, wherein ceil { } is an upward rounding function, N _ CMR is the number of elements in the CMR set, and N _ IMR is the number of elements in the IMR set. Alternatively, the bit lengths of the CMR index and the IMR index may be unified as ceil { Log2(N _ CMR + N _ IMR) }.

Table 2 is an example of a correspondence of the measured value of L1-SINR to the quantized value. As shown in table 2, L1-SINR can be quantized to a 7-bit value for reporting. Wherein the quantization step is 0.5 dB.

It should be noted that the bit length and the quantization step size in table 2 may also adopt other values according to actual requirements, for example, 12 bits, 1dB, and so on.

TABLE 2

L1-SINR quantized value	L1-SINR measurement (dB)
		L1-SINR_0	L1-SINR<-23
L1-SINR_1	-23≤L1-SINR<-22.5
		L1-SINR_2	-22.5≤L1-SINR<-22
L1-SINR_3	-22≤L1-SINR<-21.5
		L1-SINR_4	-21.5≤L1-SINR<-21
…	…
		L1-SINR_123	38≤L1-SINR<38.5
L1-SINR_124	38.5≤L1-SINR<39
		L1-SINR_125	39≤L1-SINR<39.5
L1-SINR_126	39.5≤L1-SINR<40
		L1-SINR_127	40≤L1-SINR

Exemplarily, table 3 is example two of the CSI measurement report. As shown in table 3, if the reported amounts include: CMR index, IMR index and signal to interference plus noise ratio SINR, the CSI measurement report may include the IMR index and the signal to interference plus noise ratio SINR.

It should be noted that the CSI measurement report shown in table 3 may include one or more sets of measurement results, such as two sets of measurement results with measurement result indexes 0 and 1 in table 3, where each set of measurement results includes an IMR index and an L1-SINR.

Wherein, the bit length (bitwidth) of the IMR index is ceil { Log2(N _ IMR) }, wherein ceil { } is an ceiling function, and N _ IMR is the number of elements in the IMR set. Alternatively, the bit length of the CMR index and the IMR index may also be ceil { Log2(N _ CMR + N _ IMR) }, where N _ CMR is the number of elements in the CMR set.

Similar to the L1-SINR in table 1, the L1-SINR in table 3 can also be quantized to a 7-bit value for reporting. The specific implementation manner may refer to the description related to table 2, which is not described herein again.

TABLE 3

Exemplarily, table 4 is example three of the CSI measurement report. As shown in table 4, if the reported amount includes: CMR index, IMR index and signal to interference plus noise ratio SINR, the CSI measurement report may include the IMR index or signal to interference plus noise ratio SINR, and an indicator bit corresponding to the IMR index or signal to interference plus noise ratio SINR.

It should be noted that the CSI measurement report shown in table 4 may include one or more sets of measurement results, such as two sets of measurement results with measurement result indexes 0 and 1 in table 4, where each set of measurement results includes an IMR index or an L1-SINR, and an indicator bit corresponding to the IMR index or the signal to interference plus noise ratio SINR.

Wherein, the bit length of the indicating bit is 1 bit. Illustratively, when the indicator bit is 1, the CSI measurement result includes an IMR index, and when the indicator bit is 0, the CSI measurement result includes a quantized value of L1-SINR. The reported IMR index or L1-SINR quantization value shares a set of reported bits, and the bit length of the set of reported bits may be: the bit length (bitwidth) of the IMR index and the bit length of the quantization value of L1-SINR are the maximum of { ceil { Log2(N _ IMR) },7 }. For example, if ceil { Log2(N _ IMR) } >7, when reporting L1-SINR, it is only necessary to complement 0 before or after the quantized value of L1-SINR represented by 7 bits until the bit length is the same as that of IMR index. For another example, if ceil { Log2(N _ IMR) } <7, when reporting the IMR index, 0 may be added before or after the IMR index indicated by ceil { Log2(N _ IMR) } bit until the bit length is the same as the bit length of the quantization value of L1-SINR. Optionally, ceil { Log2(N _ IMR) } may also be replaced by ceil { Log2(N _ CMR + N _ IMR) }, where N _ CMR is the number of elements in the CMR set.

Similar to the L1-SINR in Table 1, the L1-SINR in Table 4 can also be quantized to a 7-bit value for reporting. The specific implementation manner may refer to the description related to table 2, which is not described herein again.

TABLE 4

Exemplarily, table 5 is example four of the CSI measurement report. As shown in table 5, if the reported amounts include: one of the CMR index or the IMR index, and the signal to interference plus noise ratio SINR, the CSI measurement report may include one of the CMR index or the IMR index, and the signal to interference plus noise ratio SINR.

It should be noted that the CSI measurement report shown in table 5 may include one or more sets of measurement results, such as two sets of measurement results with measurement result indexes 0 and 1 in table 5, where each set of measurement results includes one of a CMR index or an IMR index, and an L1-SINR.

The IMR index and the IMR index share a set of reporting bits, and a bit length (bit width) of the set of reporting bits may be a maximum value of ceil { Log2(N _ CMR) } and ceil { Log2(N _ IMR) }. Where ceil { } is the ceiling function, N _ CMR is the number of elements in the CMR set, and N _ IMR is the number of elements in the IMR set. Or, optionally, the bit length of the set of reporting bits may also be ceil { Log2(N _ CMR + N _ IMR) }. For example, if ceil { Log2(N _ CMR) } > ceil { Log2(N _ IMR) }, when reporting the IMR index, 0 needs to be added before or after the IMR index indicated by ceil { Log2(N _ IMR) } bit until the bit length is the same as that of the CMR index. For another example, if ceil { Log2(N _ CMR) } < ceil { Log2(N _ IMR) }, when reporting the CMR index, it only needs to complement 0 before or after the CMR index represented by ceil { Log2(N _ CMR) } bit until the bit length is the same as that of the IMR index.

Otherwise, 0 is added before or after the CMR index represented by ceil { Log2(N _ CMR) } bit until the bit length is the same. Alternatively, the two categories can be classified into > and < ═ two.

Similar to the L1-SINR in Table 1, the L1-SINR in Table 5 can also be quantized to a 7-bit value for reporting. The specific implementation manner may refer to the description related to table 2, which is not described herein again.

TABLE 5

It should be noted that the measurement result indexes in tables 1 to 5 are set for convenience of description only. In the actual measurement report, there is no need to report the measurement result index, but only one or more sets of CSI measurement results shown in the above report 1-table 5.

Based on the beam measurement method shown in fig. 3, the terminal device can receive and measure signals sent by the network device on the configured CMR set and IMR set, and then deduct redundant information from the report content required by the report amount according to the beam scanning mode and the report amount configured by the network device, and report the subtracted redundant information to the network device, wherein the redundant information includes information already known by the network device, measurement results that need not be concerned in the current communication scenario, and the like, and the actually reported data amount can be effectively reduced, thereby saving interference reporting overhead, reducing resource consumption, and improving communication efficiency.

The beam measurement method provided by the embodiment of the present application is described in detail above with reference to fig. 3 to 7. The following describes a communication apparatus provided in an embodiment of the present application with reference to fig. 8.

Fig. 8 is a schematic structural diagram of a communication device according to an embodiment of the present application. The communication apparatus may be applied to the communication system shown in fig. 1, and performs the function of the terminal device in the beam measurement method shown in fig. 3. For convenience of explanation, fig. 8 shows only the main components of the communication apparatus.

As shown in fig. 8, the communication apparatus 800 includes: a processing module 801 and a transceiver module 802.

The transceiver module 802 is configured to receive measurement configuration information from a network device; the measurement configuration information is used for indicating a channel measurement resource CMR set, an interference measurement resource IMR set, a beam scanning mode and a report quantity.

The transceiver module 802 is further configured to receive signals from the network device on the CMR set and the IMR set.

A processing module 801 for measuring the received signal.

The processing module 801 is further configured to determine the content of the measurement report according to the beam scanning mode and/or the report amount.

The transceiver module 802 is further configured to send a measurement report to the network device.

Alternatively, in another possible design, if the beam scanning mode is: fixing the sending beam of the CMR set, wherein the reporting quantity comprises: one of the CMR index and the IMR index, and the signal to interference plus noise ratio, SINR, the measurement report includes the IMR index and the SINR.

In one possible design, if the reporting quantity includes: CMR index, IMR index, and signal to interference plus noise ratio, SINR, the measurement report includes either IMR index or SINR.
