Furthermore, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0038] Currently, most NR systems employ beam management mechanisms. With beamforming technology, network devices can completely cover a cell using multiple beams pointing in different directions. During downlink, network devices can transmit wireless signals using beams pointing in different directions; this process is called beam sweeping. Simultaneously, terminal devices can measure the wireless signals emitted by different beams and report relevant information about each signal to the base station. Based on the information reported by the terminal devices, the network devices determine the optimal transmission beam aimed at the terminal device.

[0039] The NR system's multi-beam system covers the entire cell using different beams, with each beam covering a smaller area. This is achieved through temporal beam scanning, allowing multiple beams to cover the entire cell.

[0040] Currently, different beams are identified by the different signals carried on the beam.

[0041] For example, different synchronization signal blocks (SSBs) are transmitted on different beams, and terminal devices can identify different beams through the SSBs.

[0042] For example, different channel state information measurement reference signals (CSI-RS) are transmitted on different beams, and terminal devices can identify different beams through CSI-RS or CSI-RS resources.

[0043] The embodiments of this application can measure and report signals carried on a beam. For example, the terminal device can measure and report CSI-RS and / or SSB.

[0044] In a multi-beam system, the terminal device needs to measure the signal and determine which beams have better transmission quality based on the measurement results. At the same time, it reports relevant information (such as which beams have better signal quality and their corresponding measurement results) to the network device.

[0045] In traditional beam measurement, the reference signal receiving power (RSRP) is usually measured and compared, and then the signal with the higher RSRP value is selected for reporting.

[0046] However, NR systems have high requirements for signal transmission quality, and the measurement results of RSRP cannot accurately reflect the signal transmission quality. Therefore, how to select the measurement quantity of the signal to reflect the signal transmission quality has become an urgent problem to be solved.

[0047] This application proposes a method for reporting measurement quantities to address the above-mentioned problems, which can accurately reflect the transmission quality of signals.

[0048] Figure 2 This application provides a method for reporting measurement quantities. Figure 2 The methods include at least some of the following.

[0049] In step 210, the terminal device determines the measurement quantities of K signals, including reference signal receiving quality (RSRQ) and / or signal to interference plus noise ratio (SINR), where K is a positive integer.

[0050] RSRQ represents signal reception quality, and to a certain extent, it can reflect the quality of signal transmission. Therefore, when terminal devices measure RSRQ and report it to network devices, it helps network devices find the optimal signal for communication with terminal devices.

[0051] The higher the RSRQ value of a signal, the better the transmission quality of that signal.

[0052] SINR is the ratio of the strength of the received useful signal to the strength of the received interference signal (noise and interference); it can be simply understood as the "signal-to-noise ratio". SINR can reflect the quality of signal transmission to a certain extent. Therefore, when terminal devices measure the SINR of a signal and report it to network devices, it helps network devices find the optimal signal for communication with terminal devices.

[0053] The higher the SINR value of a signal, the better the transmission quality of that signal.

[0054] Optionally, the measurement quantity can be RSRQ, or the measurement quantity can be SINR, or the measurement quantity can be both RSRQ and SINR.

[0055] In addition to RSRQ and / or SINR mentioned above, the measurement may also include RSRP.

[0056] In step 220, the terminal device reports the measurements of the K signals to the network device.

[0057] The technical solution provided in this application embodiment can use the RSRQ and / or SINR of a signal as a measurement quantity. RSRQ and / or SINR can reflect the signal quality to a certain extent. The terminal device can measure the RSRQ and / or SINR of K signals and report them to the network device, which helps the network device find the best signal to communicate with the terminal device.

[0058] Figure 3 This application provides a method for determining a measurement quantity. Figure 3 The methods include at least some of the following.

[0059] In step 310, the network device acquires measurements of K signals, including the reference signal reception quality (RSRQ) and / or the signal-to-interference-plus-noise ratio (SINR), where K is a positive integer.

[0060] In step 320, the network device communicates with the terminal device based on the measurements of the K signals.

[0061] The technical solution provided in this application embodiment can use the RSRQ and / or SINR of a signal as measurement quantities. RSRQ and / or SINR can reflect the signal quality to a certain extent. After receiving the measurement quantities reported by the terminal device, the network device can easily find the optimal signal to communicate with the terminal device.

[0062] The way terminal devices report measurements corresponds to the way network devices determine measurements. The two methods will be described together below.

[0063] It should be understood that some specific descriptions of the methods by which terminal devices report measurements can also be adapted to the process by which network devices determine measurements, and vice versa.

[0064] There are several ways for the terminal device to report the measurements of K signals to the network device. Step 220 is described in detail below.

[0065] As an example, the terminal device can directly report the bit value corresponding to the measurement of each of the K signals to the network device based on the correspondence between the measurement quantity and the bit value.

[0066] In this way, the terminal device only needs to look up the correspondence table between the measured quantity and the bit value, and report the bit value corresponding to the measured quantity to the network device. For the terminal device, this reporting method is relatively simple, and the processing is also relatively simple.

[0067] For network devices, after receiving the bit values ​​corresponding to the measurements of K signals reported by the terminal device, the measurement quantities of the K signals can be determined by looking up the correspondence table between the measurement quantities and the bit values, thereby finding the best signal for communication with the terminal device.

[0068] When the measurement quantity is SINR, for the correspondence between the measurement quantity and the bit value, the interval step size corresponding to the bit value in the correspondence is 0.25dB, and / or the number of bit values ​​corresponding to the SINR is 128.

[0069] Alternatively, when the measurement is SINR, in the correspondence between the measurement and the bit value, the interval between the bit values ​​corresponding to the SINR is 0.5dB, and / or the number of bit values ​​corresponding to the SINR is 128.

[0070] The following example illustrates the concept of an interval step size of 0.5dB.

[0071] Specifically, when the measured quantity is SINR, the correspondence between the measured quantity and bit values ​​can be varied. For example, in the correspondence between the measured quantity and bit values, the interval between the bit values ​​corresponding to the SINR can be 0.5 dB, meaning that every 0.5 dB interval of SINR values ​​can correspond to different bit values, and the specific range of the corresponding bit values ​​is not limited. Another example is that the bit values ​​corresponding to SINR can be positive integers greater than or equal to 0 and less than or equal to 128, and the interval between the specific bit values ​​corresponding to the SINR is not limited. Yet another example is that the interval between the bit values ​​corresponding to SINR can be 0.5 dB, and the number of bit values ​​corresponding to SINR is 128.

[0072] The correspondence between SINR and bit values ​​can be agreed upon in advance by the terminal device and the network device, or the correspondence can be indicated to the terminal device by the network device through higher-layer signaling, or the correspondence can be a predefined correspondence, for example, the correspondence specified in the standard specification.

[0073] The following explanation uses the correspondence between SINR and bit values, as shown in Table 1, as an example.

[0074] In Table 1, the SINR and bit value correspondence can be 0.5dB, and the number of bits corresponding to SINR is 128.

[0075] Table 1 shows the correspondence between SINR and bit values, describing 128 possible SINR values. Each of these 128 value ranges corresponds to one bit value, and each range can be represented using 7 bits. Therefore, when a terminal device reports the SINR of each signal, it needs to occupy 7 bits.

[0076] Therefore, when the terminal device reports the measurement of K signals using the method in Table 1, it needs to occupy 7*Kbit bits for reporting.

[0077] Table 1

[0078] Representation of reported bit values Quantities and conditions unit SINR_000 SINR<-23 dB SINR_001 -23≤SINR<-22.5 dB … … … SINR_126 39.5≤SINR<40 dB SINR_127 40≤SINR dB

[0079] It should be noted that the "Representation of Reported Bit Values" shown in Table 1 is only a sequence number and does not represent the actual reported bit values. The bit values ​​in the actual correspondence table can be the correspondence of 0 to 127 arranged in descending order, or the correspondence of 0 to 127 arranged in ascending order, or any other correspondence.

[0080] When the measured quantity is RSRQ, the correspondence between the measured quantity and the bit value can be the correspondence between SINR and bit value described above. For example, in the correspondence between RSRQ and bit value, the interval of RSRQ corresponding to the bit value is 0.5dB, and / or the number of bit values ​​corresponding to RSRQ is 128. The specific correspondence table can be referred to Table 1 above.

[0081] When the measurement quantity is RSRQ, in the correspondence between RSRQ and bit value, the interval of RSRQ corresponding to the bit value is 0.25dB, and / or the number of bit values ​​corresponding to RSRQ is 128.

[0082] When the measured quantity is RSRQ, in the correspondence between RSRQ and bit values, the interval between RSRQs corresponding to bit values ​​is 0.5 dB, and / or the bit value corresponding to the RSRQ is an integer greater than or equal to -30 and less than or equal to 46, and / or when the RSRQ is less than -34 dB, it is represented by one bit value, and / or when the RSRQ is greater than or equal to 2.5 dB, it is represented by one bit value. The specific correspondence between RSRQ and bit values ​​is shown in Table 2.

[0083] Table 2

[0084] Representation of reported bit values Quantities and conditions unit RSRQ_-30 RSRQ<-34 dB RSRQ_-29 -34≤RSRQ<-33.5 dB … … … RSRQ_-02 -20.5≤RSRQ<-20 dB RSRQ_-01 -20≤RSRQ<-19.5 dB RSRQ_00 RSRQ<-19.5 dB RSRQ_01 -19.5≤RSRQ<-19 dB RSRQ_02 -19≤RSRQ<-18.5 dB … … … RSRQ_32 -4≤RSRQ<-3.5 dB RSRQ_33 -3.5≤RSRQ<-3 dB RSRQ_34 -3≤RSRQ dB RSRQ_35 -3≤RSRQ<-2.5 dB RSRQ_36 -2.5≤RSRQ<-2 dB … … … RSRQ_45 2≤RSRQ<2.5 dB RSRQ_46 2.5≤RSRQ dB

[0085] Table 2 shows the correspondence between RSRQ and bit values, describing 77 possible value ranges for RSRQ. Each of these 77 value ranges corresponds to one bit value, and each range can be represented using 7 bits. Therefore, when a terminal device reports the RSRQ of each signal, it needs to occupy 7 bits for reporting.

[0086] It should be noted that the "Representation of Reported Bit Values" shown in Table 2 is only a sequence number and does not represent the actual reported bit values. The actual bit values ​​in the correspondence table can be the correspondence of 0 to 76 arranged in descending order, or the correspondence of 0 to 76 arranged in ascending order, or any other correspondence.

[0087] When the terminal device reports the measurement of K signals using the method in Table 2, it requires 7*Kbit bits for reporting.

[0088] Optionally, the correspondence between RSRQ and bit values ​​can be extended to more bits, or it can be a partial correspondence as shown in Table 2.

[0089] For example, the correspondence between RSRQ and bit values ​​can be shown in Table 3, which is a part of the correspondence in Table 2.

[0090] Table 3

[0091] Representation of reported bit values Quantities and conditions unit RSRQ_00 RSRQ<-19.5 dB RSRQ_01 -19.5≤RSRQ<-19 dB RSRQ_02 -19≤RSRQ<-18.5 dB … … … RSRQ_32 -4≤RSRQ<-3.5 dB RSRQ_33 -3.5≤RSRQ<-3 dB RSRQ_34 -3≤RSRQ dB

[0092] Table 3 shows the correspondence between RSRQ and bit values, describing 35 possible value ranges for RSRQ. Each of these 35 value ranges corresponds to one bit value, and each range can be represented using 6 bits. Therefore, when a terminal device reports the RSRQ of each signal, it needs to occupy 6 bits for reporting.

[0093] It should be noted that the "Representation of Reported Bit Values" shown in Table 1 is only a sequence number and does not represent the actual reported bit values. The actual correspondence can be a correspondence of bit values ​​from 0 to 34 arranged in descending order, or a correspondence of bit values ​​from 0 to 34 arranged in ascending order, or any other correspondence.

[0094] When the terminal device reports the measurement of K signals using the method in Table 3, it requires 6*Kbit bits for reporting.

[0095] The correspondence between RSRQ and bit values ​​can be agreed upon in advance by the terminal device and the network device, or the correspondence can be indicated by the network device to the terminal device through higher-layer signaling, or the correspondence can be a predefined correspondence, for example, the correspondence specified in the standard specification.

[0096] It should be noted that Table 2 can be an extension of the correspondence between the measured quantities and bit values ​​shown in Table 3. When using the correspondence shown in Table 2, for the two correspondences in Table 2, RSRQ<19.5dB and -3dB≤RSRQ, the embodiments of this application can set these two correspondences, that is, these two correspondences can be retained in the correspondence table, or they can be not set, that is, these two correspondences can be not retained in the correspondence table.

[0097] When retaining these two correspondences, the correspondence between the measured quantity and the bit value can be as shown in Table 2. When the terminal device actually reports, if the measured quantity is less than -19.5dB, or greater than or equal to -3dB, the terminal device can ignore these two correspondences, find the corresponding bit value of the measured quantity from other correspondences, and report it to the network device.

[0098] When the two correspondences are not retained, the correspondence between the measured quantity and the bit value can be the correspondence in Table 2 after deleting the two correspondences. Alternatively, it can be the correspondence obtained after deleting the two correspondences and reordering the bit values. For example, in the reordered correspondence table, when -20dB≤RSRQ<-19.5dB, the bit value is represented as 0; when -20.5dB≤RSRQ<-20dB, the bit value is -1; ...; when RSRQ<-34dB, the bit value is represented as -29. When -3dB≤RSRQ<-2.5dB, the bit value is represented as 34; when -2.5dB≤RSRQ<-2dB, the bit value is 35; ...; when 2.5dB≤RSRQ, the bit value is represented as 45.

[0099] It should be understood that, in addition to the cases described above where the interval between the measurements corresponding to the bit values ​​can be 0.25dB or 0.5dB, the interval between the measurements corresponding to the bit values ​​can also be other intervals such as 0.1dB, 0.75dB, or 1dB.

[0100] To reduce the number of bits used for reporting measurements and save signaling overhead, the terminal device can report a portion of the K signals using the methods shown in Tables 1-3, while reporting the remaining signals using other methods. The specific scheme is described below.

[0101] As another example, the terminal device can report the bit value corresponding to the measurement quantity of each of the M signals out of the K signals to the network device according to the correspondence between the measurement quantity and the bit value, where M is a positive integer and K>M.

[0102] This application does not specifically limit the method for determining the M signals. For example, the M signals can be any K signals from the K signals. Alternatively, the M signals can be the M signals with the largest measured values ​​among the K signals. Another example is that the M signals with the smallest measured values ​​among the K signals. Yet another example is that the M signals are the M signals whose measured values ​​are in the middle among the K signals.

[0103] When the measurement is SINR, the terminal device can report the measurement of each of the M signals out of the K signals as shown in Table 1. The specific reporting method can be found in the description above. Reporting the measurement of these M signals requires 7*M bits.

[0104] When the measurement quantity is RSRQ, the terminal device can report the measurement quantity of each of the M signals out of the K signals in the manner shown in Table 2. The specific reporting method can be found in the description above. Reporting the measurement quantity of these M signals requires 7*M bits.

[0105] Alternatively, when the measurement is RSRQ, the terminal device can report the measurement of each of the M signals out of the K signals in the manner shown in Table 3. The specific reporting method can be found in the description above. Reporting the measurement of these M signals requires 6*M bits.

[0106] There are multiple ways for the terminal device to report the remaining (KM) signals. The terminal device can determine the bit value corresponding to the measurement of each of the (KM) signals based on the measurement of at least some of the M signals and the measurement of the (KM) signals; then the terminal device reports the bit value corresponding to the measurement of each of the (KM) signals to the network device.

[0107] As one implementation, the terminal device can generate a difference value corresponding to the measurement of each of the (KM) signals according to the measurement of at least some of the signals in the M signals and the measurement of (KM) signals in a differential manner; then the terminal device can determine the bit value corresponding to the measurement difference value of each of the (KM) signals according to the correspondence between the difference value and the bit value, and report the bit value corresponding to the measurement difference value of each of the (KM) signals to the network device.

[0108] For network devices, after receiving the bit values ​​corresponding to the differences of (KM) signals reported by the terminal device, they can determine the differences of the measured quantities of (KM) signals based on the correspondence between the differences and the bit values. Then, based on the measured quantities of at least some of the M signals, they can determine the measured quantities of (KM) signals in a differential manner.

[0109] There are multiple ways for a terminal device to generate the difference between the measured quantities of each of the (KM) signals.

[0110] For example, the terminal device can differentiate the measured quantities of (KM) signals with the measured quantity of one of the M signals to obtain the difference between the measured quantities of each of the (KM) signals.

[0111] The terminal device can use any one of the M signals as a reference to perform differential operations on the (KM) signals to obtain the difference between the measured quantity of each of the (KM) signals and the measured quantity of that arbitrary signal among the M signals.

[0112] Any one of the M signals can be the signal with the largest measurement, the signal with the smallest measurement, or the signal with a measurement in the middle position.

[0113] In this embodiment, the signal with the largest measurement value, the signal with the smallest measurement value, or the signal with a measurement value in the middle among the M signals can be selected based on the actual distribution of the measurement values.

[0114] Preferably, after the measured value of the signal selected from the M signals is differentially divided with the (KM) signals, the difference between the measured values ​​of the (KM) signals can mainly fall within the dynamic range of the difference.

[0115] For example, the terminal device can perform a difference between the measured quantity of the i-th signal and the measured quantity of the (i-1)-th signal out of (K-M+1) signals to generate the difference value of the measured quantity of the i-th signal, where i = {2, 3, ..., K-M+1}, the (K-M+1) signals include (KM) signals other than M signals out of K signals, and one signal out of M signals, and the first signal out of (K-M+1) signals is one of the M signals.

[0116] For network devices, the difference between the measured value of the i-th signal among (K-M+1) signals and the measured value of the (i-1)-th signal can be differentially divided to generate the measured value of the i-th signal, where i = {2, 3, ..., K-M+1}. The (K-M+1) signals include the (KM) signals and one of the M signals, and the first signal among the (K-M+1) signals is one of the M signals.

[0117] It should be understood that (KM) signals refer to the (KM) signals included in the second to (K-M+1)th signals out of the (K-M+1) signals. The difference between the measured values ​​of the second to (K-M+1)th signals is used to obtain the difference between the measured values ​​of each of the (KM) signals.

[0118] Any one of the M signals can be the signal with the largest measured value, the signal with the smallest measured value, or the signal with a measured value in the middle position.

[0119] Specifically, the terminal device can use any one of the M signals as a reference and take one of the M signals as the first signal. The (KM) signals are the second, third, ..., (K-M+1)th signals in sequence.

[0120] The difference between the measured values ​​of the i-th signal is the difference between the measured value of the i-th signal and the measured value of the (i-1)-th signal. Therefore, the terminal device can obtain the difference between the measured values ​​of each of the (KM) signals using this method.

[0121] Before the terminal device performs a difference operation between the measured quantity of the i-th signal and the measured quantity of the (i-1)-th signal in the (K-M+1)-th signals to generate the difference value of the measured quantity of the i-th signal, the terminal device can sort the (KM)-th signals according to the magnitude of the measured quantity.

[0122] For example, the measurements of (KM) signals can be sorted in descending order or in ascending order.

[0123] By first sorting the signals and then performing differential analysis on the (KM) signals, the relative quality of the (KM) signals can be more intuitively represented. After receiving the measurements reported by the terminal devices, the network devices can more easily distinguish the quality of the signals, which helps them determine the optimal signal for communication with the terminal devices.

[0124] There are several ways to correspond the difference to the bit value, which will be described in detail below.

[0125] For example, the interval between the differences corresponding to a bit value can be 2dB, and / or the bit value corresponding to the difference can be an integer greater than or equal to 0 and less than or equal to 15. Specific correspondences are shown in Tables 4-7.

[0126] When the difference is less than 2dB, the bit value is 0; when the difference is greater than or equal to 30dB, the bit value is 15. The specific correspondence is shown in Table 4. After obtaining the difference in the measured signal quantity according to the method described above, the terminal device can look up the corresponding bit value according to Table 4 and report the corresponding bit value to the network device.

[0127] Table 4

[0128] Representation of reported bit values Difference and Condition unit 00 Difference < 2 dB 01 2≤difference<4 dB … … … 14 28≤difference<30 dB 15 30≤difference dB

[0129] When the difference is less than or equal to 2dB, the bit value is 0; when the difference is greater than 30dB, the bit value is 15. The specific correspondence is shown in Table 5. After obtaining the difference in the measured signal quantity according to the method described above, the terminal device can look up the corresponding bit value according to Table 5 and report the corresponding bit value to the network device.

[0130] Table 5

[0131] Representation of reported bit values Difference and Condition unit 00 Difference ≤ 2 dB 01 2 < difference value ≤ 4 dB … … … 14 28 < difference value ≤ 30 dB 15 30 <Difference dB

[0132] When the difference is less than 2dB, the bit value is 15; when the difference is greater than or equal to 30dB, the bit value is 0. The specific correspondence is shown in Table 6. After obtaining the difference in the measured signal quantity according to the method described above, the terminal device can look up the corresponding bit value according to Table 6 and report the corresponding bit value to the network device.

[0133] Table 6

[0134] Representation of reported bit values Difference and Condition unit 15 Difference < 2 dB 14 2≤difference<4 dB … … … 01 28≤difference<30 dB 00 30≤difference dB

[0135] When the difference is less than or equal to 2dB, the bit value is 15; when the difference is greater than 30dB, the bit value is 0. The specific correspondence is shown in Table 7. After obtaining the difference in the measured signal quantity according to the method described above, the terminal device can look up the corresponding bit value according to Table 7 and report the corresponding bit value to the network device.

[0136] Table 7

[0137] Representation of reported bit values Difference and Condition unit 15 Difference ≤ 2 dB 14 2 < difference value ≤ 4 dB … … … 01 28 < difference ≤ 30 dB 00 30 <Difference dB

[0138] Tables 4-7 show the correspondence between differences and bit values, describing 16 possible ranges for the differences. Each of these 16 ranges corresponds to a single bit value, and each range can be represented using 4 bits. Therefore, when a terminal device reports the difference in a signal measurement using any of the methods shown in Tables 4-7, it requires 4 bits for reporting.

[0139] Therefore, when the terminal device reports (KM) signals using any of the methods shown in Tables 4-7, it requires 4*(KM) bits. When the terminal device reports M signals using the method in Table 1 and (KM) signals using any of the methods shown in Tables 4-7, it requires a total of 7*M + 4*(KM) bits. Compared to reporting K signals using either Table 1 or Table 2, which requires 7*K bits, this method saves resources and reduces signaling overhead.

[0140] In the correspondence between the difference and the bit value shown in Tables 4-7, the interval between the difference values ​​corresponding to the bit values ​​is 2dB. The embodiments of this application provide another correspondence, which can reduce the interval between the difference values ​​corresponding to the bit values ​​and improve the accuracy of the measurement quantity reported by the terminal device.

[0141] Specifically, the interval between the differences corresponding to the bit values ​​can be 1dB, and / or the bit values ​​corresponding to the differences can be integers greater than or equal to 0 and less than or equal to 15.

[0142] The following is a detailed description of the correspondence between the differences and bit values ​​shown in Tables 8-11.

[0143] When the difference is less than 1 dB, the bit value is 0; when the difference is greater than or equal to 15 dB, the bit value is 15. The specific correspondence is shown in Table 8. After obtaining the difference of the measured signal quantity according to the method described above, the terminal device can look up the corresponding bit value according to Table 8 and report the corresponding bit value to the network device.

[0145] Representation of reported bit values Difference and Condition unit 00 Difference < 1 dB 01 1≤difference<2 dB … … … 14 14 ≤ difference < 15 dB 15 15≤difference dB

[0146] When the difference is less than or equal to 1 dB, the bit value is 0; when the difference is greater than 15 dB, the bit value is 15. The specific correspondence is shown in Table 9. After obtaining the difference of the measured signal quantity according to the method described above, the terminal device can look up the corresponding bit value according to Table 9 and report the corresponding bit value to the network device.

[0148] Representation of reported bit values Difference and Condition unit 00 Difference ≤ 1 dB 01 1 < difference value ≤ 2 dB … … … 14 14 < difference value ≤ 15 dB 15 15 < Difference dB

[0149] When the difference is less than 1 dB, the bit value is 15; when the difference is greater than or equal to 15 dB, the bit value is 0. The specific correspondence is shown in Table 10. After obtaining the difference in the measured signal quantity according to the method described above, the terminal device can look up the corresponding bit value according to Table 10 and report the corresponding bit value to the network device.

[0151] Representation of reported bit values Difference and Condition unit 15 Difference < 1 dB 14 1≤difference<2 dB … … … 01 14 ≤ difference < 15 dB 00 15≤difference dB

[0152] When the difference is less than or equal to 1 dB, the bit value is 15; when the difference is greater than 15 dB, the bit value is 0. The specific correspondence is shown in Table 11. After obtaining the difference of the measured signal quantity according to the method described above, the terminal device can look up the corresponding bit value according to Table 11 and report the corresponding bit value to the network device.

[0153] Table 11

[0154] Representation of reported bit values Difference and Condition unit 15 Difference ≤ 1 dB 14 1 < difference value ≤ 2 dB … … … 01 14 < difference value ≤ 15 dB 00 15 <Difference dB

[0155] The methods shown in Tables 8-11 describe the 16 possible ranges of the difference. The terminal device only needs 4 bits to report the difference of the measurement of each signal, which can save signaling overhead.

[0156] Reporting according to the methods shown in Tables 8-11 can reduce the step size of the difference and improve the accuracy of the measurement reported by the terminal device. However, the dynamic range of the difference is only within the range of 1dB to 15dB, which is relatively small. Therefore, this application proposes an alternative correspondence that can ensure the reporting accuracy of the terminal device without affecting the dynamic range of the difference.

[0157] Specifically, the interval between the differences corresponding to the bit values ​​can be 1 dB, and / or the bit values ​​corresponding to the differences can be integers greater than or equal to 0 and less than or equal to 31.

[0158] The following is a detailed description of the correspondence between the differences and bit values ​​shown in Tables 12-15.

[0159] When the difference is less than 1 dB, the bit value is 0; when the difference is greater than or equal to 31 dB, the bit value is 31. The specific correspondence is shown in Table 12. After obtaining the difference of the measured signal quantity according to the method described above, the terminal device can look up the corresponding bit value according to Table 12 and report the corresponding bit value to the network device.

[0161] Representation of reported bit values Difference and Condition unit 00 Difference < 1 dB 01 1≤difference<2 dB … … … 30 30≤difference<31 dB 31 31≤difference dB

[0162] When the difference is less than or equal to 1 dB, the bit value is 0; when the difference is greater than 31 dB, the bit value is 31. The specific correspondence is shown in Table 13. After obtaining the difference of the measured signal quantity according to the method described above, the terminal device can look up the corresponding bit value according to Table 13 and report the corresponding bit value to the network device.

[0164] Representation of reported bit values Difference and Condition unit 00 Difference ≤ 1 dB 01 1 < difference ≤ 2 dB … … … 30 30 < difference ≤ 31 dB 31 31 <Difference dB

[0165] When the difference is less than 1 dB, the bit value is 31; when the difference is greater than or equal to 31 dB, the bit value is 0. The specific correspondence is shown in Table 14. After obtaining the difference in the measured signal quantity according to the method described above, the terminal device can look up the corresponding bit value according to Table 14 and report the corresponding bit value to the network device.

[0167] Representation of reported bit values Difference and Condition unit 31 Difference < 1 dB 30 1≤difference<2 dB … … … 01 30≤difference<31 dB 00 31≤difference dB

[0168] When the difference is less than or equal to 1 dB, the bit value is 31; when the difference is greater than 31 dB, the bit value is 0. The specific correspondence is shown in Table 15. After obtaining the difference of the measured signal quantity according to the method described above, the terminal device can look up the corresponding bit value according to Table 15 and report the corresponding bit value to the network device.

[0169] Table 15

[0170] Representation of reported bit values Difference and Condition unit 31 Difference ≤ 1 dB 30 1 < difference value ≤ 2 dB … … … 01 30 < difference ≤ 31 dB 00 31 <Difference dB

[0171] Tables 12-15 show the correspondence between differences and bit values, describing 32 possible ranges for the differences. Each of these 32 ranges corresponds to one bit value, and each range can be represented using 5 bits. Therefore, when a terminal device reports the difference in a signal measurement using any of the methods shown in Tables 12-15, it requires 5 bits for reporting.

[0172] Compared to reporting all K signals according to the bit value corresponding to the measurement, reporting some of the K signals according to the difference between the measured values ​​can reduce the number of bits occupied by the reported measurement values ​​and save signaling overhead.

[0173] Furthermore, in addition to the method described above of differentiating the measured quantities of (KM) signals with the measured quantity of one of the M signals, the embodiments of this application can also differentiate the measured quantities of (KM) signals with the measured quantities of multiple signals among the M signals. For example, the measured quantities of (KM) signals can be differentiated with the average value of the measured quantities of multiple signals among the M signals. The specific differentiation method is not limited in the embodiments of this application.

[0174] It should be understood that the interval between the bit values ​​can be 1dB or 2dB as described above, as well as other intervals such as 0.25dB, 0.5dB, and 0.75dB.

[0175] The correspondence between the difference and the bit value can be agreed upon in advance by the terminal device and the network device, or the correspondence can be indicated to the terminal device by the network device through higher-layer signaling, or the correspondence can be a predefined correspondence, for example, the correspondence specified in the standard specification.

[0176] The above example only illustrates the differential method; at least some of the M signals can also be processed in other ways. For instance, the terminal device can generate a ratio corresponding to the measurement of each of the (KM) signals by dividing the measurements of at least some of the M signals and (KM) signals. Then, the terminal device can report the bit value corresponding to the ratio of the measurement of each of the (KM) signals to the network device based on the correspondence between the ratio and the bit value.

[0177] Optionally, the terminal device can measure the quantities of N signals, select K signals from the N signals, and report the quantities of the K signals.

[0178] Wherein, the measurement quantity of the K signals is the measurement quantity of the K signals with the largest measurement quantity among the N signals, and / or the measurement quantity of each of the K signals is greater than a preset threshold, where N is a positive integer and N≥K.

[0179] Specifically, the K signals can be the K signals with the largest measured values ​​among the N signals, or the K signals can be any K signals among the N signals whose measured values ​​are greater than a preset threshold, or the K signals can be the K signals among the N signals whose measured values ​​are greater than a preset threshold and whose measured values ​​are the largest.

[0180] Optionally, the K signals can be carried on K beams. For example, one signal can be carried on each beam.

[0181] After determining the optimal signal, network devices can find the best beam for communication with terminal devices based on the correspondence between the signal and the beam.

[0182] Optionally, the K signals may include SSB and / or CSI-RS. For example, all K signals may be SSB, all K signals may be CSI-RS, or some of the K signals may be SSB and some may be CSI-RS.

[0183] Optionally, the terminal device can report the indices of the K signals to the network device along with the measured quantities of the K signals. This way, after receiving the measured quantities and indices of the K signals reported by the terminal device, the network device can identify the signal corresponding to each measured quantity, which helps the network device select the optimal signal for communication with the terminal device.

[0184] Optionally, before determining the measurement quantities of the K signals, the terminal device may receive configuration information sent by the network device, which indicates the measurement quantities that the terminal device needs to measure.

[0185] For example, the configuration information can instruct the terminal device to measure only the SINR of the signal, or the configuration information can instruct the terminal device to measure only the RSRQ of the signal, or the configuration information can instruct the terminal device to measure both the SINR and RSRQ of the signal.

[0186] It should be noted that this configuration information can also instruct the terminal device to measure the RSRP of the signal. Specifically, the RSRP can be reported in the traditional way or in any of the ways described above.

[0187] Optionally, the configuration information can be sent differently for different terminal devices. For example, for newly added terminal devices, the configuration information can instruct the terminal devices to measure the SINR and / or RSRQ of the signal, while for older terminal devices, the configuration information can instruct the terminal devices to measure the RSRP of the signal.

[0188] Optionally, the SINR mentioned in this application is the SINR of layer 1 (L1), i.e., L1-SINR, and the RSRQ is L1-RSRQ.

[0189] It should be noted that the correspondence shown in Tables 1-15 is only a specific implementation of the embodiments of this application and does not limit the embodiments of this application. Any correspondence obtained by modification on this basis is within the protection scope of this application.
