Assuming that M is the number of predicted time units, the number of RSRP reported in each time unit is Q, then the P*M measurement values use the differential quantization method, and the total number of bits required is: (7+4*(Q-1))*M, and the quantifiable differential range is 30 dB.

[0098] Optionally, in the embodiments of the present application, the configuration information associated with the first report can be at least one of inference configuration information and measurement configuration information of an AI unit. The AI unit is used to predict the beam quality corresponding to a second beam information set according to the beam quality corresponding to a first beam information set.

[0099] The number of predicted time units can be understood as the number of time units corresponding to the second beam information set.

[0100] The terminal can assist the terminal in determining the quantization manner information based on the number of predicted time units, and the quantization manner information comprises quantization using a first quantization reference value, quantization using a second quantization reference value, or quantization using the first quantization reference value and the second quantization reference value. For example, when the number of predicted time units is too large, the correlation between the beam quality reporting values corresponding to time units far apart is low, and these time units are not suitable for sharing a quantization reference value, i.e., not suitable for quantization using the first quantization reference value. For another example, when the number of predicted time units is not too large, the beam quality reporting values corresponding to multiple time units have high correlation in time, and these time units can share a quantization reference value, i.e., quantization using the first quantization reference value. When quantization using the first quantization reference value is used, it is beneficial to save the reporting overhead.

[0101] A2: a number of measured time units.

[0102] The number of measured time units can be understood as the number of time units associated with the first beam information set.

[0103] The terminal measures a corresponding number of time units based on the number of measured time units, obtains the beam quality reporting values of the M time units, and determines the adopted quantization reference value based on the number of measured time units.

[0104] A3: interval of predicted time units.

[0105] In the embodiments of the present application, the interval of predicted time units can be understood as the interval between the multiple time units corresponding to the second beam information set. When the interval of predicted time units is different, different quantization reference values are adopted to obtain quantization results of different bits, and therefore, the interval of predicted time units is beneficial for the terminal to select a suitable quantization parameter value.

[0106] For example, when the interval of time units is too large, the correlation between the beam quality reporting values corresponding to the time units far apart is low, and the first quantization reference value alone may not be suitable, in which case, the second quantization reference value + the second differential value can be adopted, or the first quantization reference value + the second quantization reference value + the second differential value can be adopted, or the first quantization reference value + the first differential value + the second quantization reference value + the second differential value can be adopted to obtain the quantization result.

[0107] A4: interval of measured time units.

[0108] In the embodiments of the present application, the interval of measured time units can be understood as the interval between the multiple time units associated with the first beam information set.

[0109] When the interval of measured time units is different, different quantization reference values are adopted to obtain quantization results of different bits, and therefore, the interval of measured time units is beneficial for the terminal to select a suitable quantization reference value.

[0110] A5: first beam information set associated with at least two measured time units.

[0111] The first beam information set can be understood as the input beam information set of the AI unit. When selecting the quantization reference value, the terminal can select different quantization reference values based on whether the beam information associated with the first beam information set associated with the at least two time units is the same.

[0112] The input beam information set can also be referred to as set B, or the beam information set corresponding to the input of the AI unit, or the beam information set corresponding to the input, or the beam information set corresponding to the input data, or the beam information set corresponding to the inference sample.

[0113] A6: a second beam information set associated with the at least two time units.

[0114] The second beam information set can be understood as the output beam information set of the AI unit. When selecting the quantization reference value, the terminal can select different quantization reference values based on whether the beam information associated with the second beam information set associated with the at least two time units is the same.

[0115] The output beam information set can also be referred to as set A, or the beam information set corresponding to the output of the AI unit, or the predicted beam information set.

[0116] A7: a function of the artificial intelligence AI unit, the function including a time domain beam prediction function or a spatial domain beam prediction function.

[0117] In the embodiments of the present application, the time domain beam prediction function can be represented by BM-CASE2, and the spatial domain beam prediction function can be represented by BM-CASE1.

[0118] Alternatively, the time domain beam prediction function can also be described as time domain beam prediction, time domain beam management, or multi-time unit beam prediction.

[0119] Alternatively, the spatial domain beam prediction function can also be described as spatial domain beam prediction, spatial domain beam management, or single-time unit beam prediction.

[0120] In the embodiments of the present application, a suitable quantization method can be determined based on the function. Specifically, since BM-CASE2 can correspond to multiple measured time units or multiple predicted time units, when the function is BM-CASE2, quantization based on the first quantization reference value can utilize the correlation between multiple time units to reduce feedback overhead. For example, when the function is BM-CASE1, the quantization method of the second quantization reference value + the second differential value is used; and for BM-CASE2, the quantization method of the first quantization reference value or the first quantization reference value + the second reference value can be used.

[0121] The AI unit in the embodiments of the present application can also be referred to as an AI model, a machine learning (ML) model, an ML unit, an AI structure, an AI function, an AI feature, a machine learning model, a neural network, a neural network function, a neural network function, etc., or the AI unit / AI model can refer to a processing unit capable of implementing specific algorithms, formulas, processing flows, capabilities, etc. related to AI, or the AI unit / AI model can be a processing method, algorithm, function, module or unit for a specific data set, or the AI unit / AI model can be a processing method, algorithm, function, module or unit running on AI / ML related hardware such as a graphics processing unit (GPU), a neural network processing unit (NPU), a tensor processing unit (TPU), an application-specific integrated circuit (ASIC), etc. The present application does not make specific limitations. Optionally, the specific data set includes at least one of the input and output of the AI unit / AI model.

[0176] Optionally, after determining that the quantization information includes the first quantization reference value, the method further includes:

[0181] Here, the difference between the M beam quality reporting values refers to the difference between the maximum value and the minimum value in the M beam quality reporting values.

[0182] In the embodiment of the present application, in the case where the first indication information satisfies the first condition, if the difference between the M beam quality reporting values is greater than or equal to the ninth threshold, the quantization manner based on the first quantization reference value and the second quantization reference value can reduce the bit number of the quantization result and expand the quantization difference range compared with the quantization scheme in the related art, and this quantization processing manner can also be described as a double difference processing manner.

[0186] In the embodiment of the present application, in the case where the M is greater than or equal to the tenth threshold, a larger quantization difference range is needed, and therefore, it is suitable to use the first quantization reference value and the second quantization reference value for quantization.

[0187] (3) The interval of the predicted or measured time units is greater than an eleventh threshold.

[0188] Optionally, in the case where the interval of the predicted or measured time units is greater than or equal to the eleventh threshold, the determination of the quantization information further comprises a second quantization reference value.

[0189] In the embodiment of the present application, in the case where the interval of the predicted or measured time units is greater than or equal to the eleventh threshold, a larger quantization difference range is needed, and therefore, it is suitable to use the first quantization reference value and the second quantization reference value for quantization.

[0190] (4) The number of the predicted or measured time units is greater than a twelfth threshold.

[0191] Optionally, in a case where the number of predicted or measured time units is greater than or equal to the twelfth threshold, determining the quantization information further includes a second quantization reference value.

[0192] In a case where the number of predicted or measured time units is greater than or equal to the twelfth threshold in the embodiments of the present application, a larger quantization differential range is needed, and therefore, the first quantization reference value and the second quantization reference value are suitable for being used for quantization.

[0193] Optionally, the terminal determines the quantization information according to the beam quality reporting values of the M time units, including at least one of the following:

[0194] In a case where the fourth condition is met, determining the quantization information includes the first quantization reference value and the second quantization reference value.

[0195] In a case where the fifth condition is met, determining the quantization information includes the first quantization reference value or the second quantization reference value.

[0196] The fourth condition includes at least one of the following:

[0197] D1: a difference value of the beam quality reporting values of the M time units is greater than a thirteenth threshold;

[0198] Optionally, the D1 item can be that the difference value of the beam quality reporting values of the M time units is greater than or equal to the thirteenth threshold.

[0208] In the case of meeting the fourth condition described above, a larger quantization difference range is required, and therefore, a double-difference quantization manner is suitable, that is, the first quantization reference value and the second quantization reference value are used for quantization. In the case of meeting the fifth condition described above, a larger quantization difference range is not required, and therefore, a single-difference quantization manner is suitable, and therefore, the first quantization reference value or the second quantization reference value is used for quantization. The double-difference quantization manner in the embodiments of the present application has a larger quantizable difference range relative to the single-difference quantization manner. For example, when the double-difference quantization manner is used, the quantizable difference range is 30 dB, and when the double-difference quantization manner is used, the quantizable difference range is 60 dB. That is, in the case of the same number of quantization bits, the double-difference quantization manner has higher quantization precision relative to the single-difference quantization manner, and the terminal can further select the first quantization reference value or the first quantization reference value and the second quantization reference value for quantization processing based on the quantization precision, so as to obtain higher quantization precision on the premise of reducing reporting overhead.

[0209] For example, the first quantization reference value is -60 dB, and the existing difference value uses a 4-bit quantization manner, and therefore, the quantizable difference range is 30 dB, that is, the reporting value within -90 dB can be represented, and if the beam quality reporting value is -100 dB, the beam quality reporting value can only be quantized to -90 dB. When the first quantization reference value and the second quantization reference value are used for quantization, the quantizable difference range is 60 dB, and if the beam quality reporting value is -100 dB, the beam quality reporting value after quantization is still -100 dB, and there is no need to be quantized to -90 dB.

[0210] Optionally, in the case that the quantization information is determined according to the beam quality reporting values of the M time units, the first report includes the quantization result and second indication information, and the second indication information is used to indicate the quantization information to the network side device.

[0211] In the embodiment of the present application, in the case that the terminal determines the quantization information based on the beam quality reporting value of M time units, the network side device is indicated the quantization information in the first report, so that the network side learns the quantization method adopted by the terminal, and the network side device and the terminal have consistent understanding of the quantization method of the quantization result.

[0212] Optionally, the quantization result includes the first quantization reference value and a first difference value, wherein the first difference value includes the difference between the beam quality reporting value of each time unit and the first quantization reference value.

[0213] Alternatively, the quantization result includes a second difference value and a second quantization reference value corresponding to each time unit, wherein the second difference value includes the difference between the second quantization reference value and the beam quality reporting value corresponding to each beam information in the corresponding time unit.

[0214] Alternatively, the quantization result includes a second difference value and second quantization reference value information corresponding to each time unit, and the second quantization reference value information includes a first quantization reference value and a target first difference value of each time unit, and the target first difference value is the minimum value of the plurality of first difference values corresponding to the time unit.

[0215] In the embodiment of the present application, in the case that the quantization information includes the first quantization reference value, the quantization result includes the first quantization reference value and the first difference value; in the case that the quantization information includes the second quantization reference value of each time unit, the quantization result includes the second difference value and the second quantization reference value of each time unit; in the case that the quantization information includes the first quantization reference value and the second quantization reference value, the quantization result includes the second difference value and the second quantization reference value information corresponding to each time unit.

[0216] It should be noted that the first threshold to the twelfth threshold in the embodiment of the present application can be configured by the network side device or agreed by the protocol, and the first condition or the second condition in the embodiment of the present application can be configured by the network side device or agreed by the protocol.

[0224] In the embodiment of the application, the network-side device configures the above quantization manner information, so that the terminal can directly quantize the beam quality reporting values of the M time units according to the quantization manner information, thereby reducing the calculation overhead of the terminal side due to the decision of the above quantization manner information. In addition, the network-side device configures the above quantization manner information based on information that can be obtained by the network-side device, for example, based on information reported by other UEs (such as beam quality information reported by other UEs) or physical configuration information of the network-side device (such as antenna configuration and beam configuration), so that the network-side device can configure the quantization manner information more suitable for the beam quality reporting values of the M time units.

In a case where the configuration information associated with the first report satisfies the sixth condition, it is determined that the first indication information comprises quantization manner information of quantization with the first quantization reference value, that is, in a case where the configuration information associated with the first report satisfies the sixth condition, the terminal is configured to quantize with the first quantization reference value.

[0239] In a case where the configuration information associated with the first report satisfies a sixth condition, it is determined that the first indication information includes quantization manner information of quantization with the first quantization reference value. It can be understood that the terminal does not expect to receive the first indication information including the quantization manner information of quantization with the first quantization reference value in a case where the sixth condition is not satisfied.

[0251] The interval of the time units of measurement in the configuration information is greater than an eighth threshold.

[0252] The implementation process of determining that the first indication information includes quantization manner information of quantization with the second quantization reference value based on the seventh condition can refer to the implementation process of determining that the quantization information includes the second quantization reference value based on the second condition described above, which will not be described here.

[0253] Optionally, the network-side device configures the second quantization reference value in the case of satisfying a seventh condition. In the case of the configuration information associated with the first report satisfying the seventh condition, the first indication information comprises quantization manner information of quantization by using the second quantization reference value, that is, in the case of the configuration information associated with the first report satisfying the seventh condition, the terminal is configured to quantize by using the second quantization reference value.

[0254] In the case of the configuration information associated with the first report satisfying the seventh condition, the first indication information comprises quantization manner information of quantization by using the second quantization reference value, which can be understood as that the terminal does not expect to receive the configuration of the first indication information comprising the quantization manner information of quantization by using the second quantization reference value in the case of not satisfying the seventh condition.

[0255] Optionally, the first indication information comprises the configuration information associated with the first report; and the configuration information comprises at least one of the following:

[0266] Alternatively, the quantization result includes a second difference value and second quantization reference value representation information corresponding to each of the time units, and the second quantization reference value representation information includes a first quantization reference value and a target first difference value of each of the time units, the target first difference value being the minimum value of the plurality of first difference values corresponding to the time unit.

[0268] In the embodiment, the quantization information is determined according to the beam quality reporting values of at least two time units or the first indication information sent by the network side device. The quantization reference value is determined based on the beam quality reporting values of the M time units or the first indication information of the network side device, so that the purpose of flexibly determining the quantization reference value is achieved, and then the quantization reference value with a smaller quantization scale number can be selected to quantize the beam quality reporting values of the plurality of time units, thereby facilitating saving of reporting overhead.

[0269] The information transmission method of the present application will be described below in conjunction with embodiments.

[0270] Embodiment One

[0271] As shown in FIG. 7, the embodiment one includes:

[0272] Step 700: The network side device determines first indication information according to a sixth condition or a seventh condition.

[0273] The step 700 is an optional step. The sixth condition and the seventh condition have been described in detail in the above description, and will not be described herein.

[0274] In the embodiment, the network side device can also determine the first indication information based on the historical beam quality reporting results of the terminal, or based on at least one of the historical beam quality reporting results of the terminal, the sixth condition and the seventh condition. In this way, the quantization manner determined by the network side device can avoid the problem of excessive expansion of reporting overhead. In this step, the network side device can also determine the first indication information based on a network side implementation algorithm.

[0275] Step 701: The base station sends the first indication information to the terminal, and the first indication information includes quantization manner information using at least one of the first quantization reference value and the second quantization reference value for quantization.

[0280] Step 702: The terminal quantizes the beam quality reporting values of the M time units according to the first indication information, obtains a quantization result, and generates a first report based on the quantization result.

[0281] Optionally, the first report includes the quantization result.

[0282] Step 703: The terminal sends the first report to the base station.

[0283] In the above embodiment one, the network side directly configures the quantization mode of the beam quality reporting values of the multiple time units, so that the terminal can determine which quantization mode to use when reporting the beam quality reporting values of the multiple time units (such as when reporting the inference result of the time domain beam prediction, or when reporting the continuous multiple measurement results of the time domain beam prediction), thereby reducing the calculation overhead required for the terminal side to determine the quantization mode.

[0284] Embodiment two:

[0285] As shown in FIG. 8, this embodiment two includes:

[0286] Step 801: The base station sends first indication information to the terminal, and the first indication information includes configuration information associated with the first report.

[0287] The configuration information includes at least one of the following:

[0288] The number of predicted time units;

[0289] The number of measured time units;

[0290] The interval of the predicted time units;

[0291] The interval of the measured time units;

[0292] A first beam information set associated with at least two measured time units;

[0293] A second beam information set associated with at least two predicted time units;

[0294] The function of the AI unit, which includes a time domain beam prediction function or a spatial domain beam prediction function.

[0295] Step 802: The terminal determines quantization information according to the configuration information, quantizes the beam quality reporting values of the M time units based on the quantization information, obtains a quantization result, and generates a first report based on the quantization result.

[0296] The quantization information includes at least one of a first quantization reference value and at least one second quantization reference value.

[0297] The implementation process of determining the quantization information based on the configuration information has been described in detail in the above description, which will not be repeated here.

[0298] Optionally, the first report includes the quantization result.

[0299] Step 803: The terminal sends the first report to the base station.

[0300] In this embodiment two, the terminal can determine the quantization manner of the beam quality reporting values of the plurality of time units based on the configuration information associated with the first report, without the network side separately configuring the quantization manner, thereby reducing the signaling overhead caused by the network side separately configuring the indication.

[0301] Embodiment three:

[0302] As shown in FIG. 9, this embodiment three includes:

[0303] Step 901: The base station sends the configuration information associated with the first report to the terminal.

[0304] The configuration information includes at least one of:

[0305] The number of predicted time units;

[0306] The number of measured time units;

[0307] The interval of predicted time units;

[0308] The interval of measured time units;

[0309] A first beam information set associated with at least two measured time units;

[0310] A second beam information set associated with at least two predicted time units;

[0311] The function of the AI unit includes a time domain beam prediction function or a spatial domain beam prediction function.

[0312] Step 902: The terminal obtains the beam quality prediction result of the M time units based on the configuration information, determines the quantization information based on the prediction result, performs quantization processing on the beam quality reporting values of the M time units based on the quantization information, obtains the quantization result, and generates the first report based on the quantization result.

[0313] Optionally, this step 902 can also be that the terminal determines the quantization information based on the configuration information and the beam quality prediction result of the M time units.

[0314] The scheme of determining the quantization information based on the beam quality prediction result has been described in the above description, which will not be repeated here.

[0315] Optionally, as an implementation manner, the quantization result includes a first quantization reference value (a maximum beam quality reporting value in a plurality of time units), and a first differential value (a differential value between the first quantization reference value and a beam quality reporting value of another beam in the plurality of time units), in which implementation manner, the terminal performs a combined reporting processing on the beam quality reporting values of the plurality of time units, i.e., reporting the beam quality reporting values of the plurality of time units through a same first report.

[0316] Optionally, as an implementation manner, the quantization result includes a second quantization reference value of each time unit (a maximum beam quality reporting value in each time unit), and a second differential value (a differential value between the second quantization reference value of each time unit and a beam quality reporting value of another beam in the time unit), in which implementation manner, the terminal performs a combined reporting processing on the beam quality reporting values of the plurality of time units, i.e., reporting the beam quality reporting values of the plurality of time units through a same first report.

[0317] Optionally, as an implementation manner, the quantization result includes a first quantization reference value, a target first differential value of each time unit (a differential value between the first quantization reference value and a maximum beam quality reporting value in each time unit), and a second differential value (a differential value between a second quantization reference value in each time unit and a beam quality reporting value of another beam in the corresponding time unit), in which implementation manner, the beam quality reporting values of the plurality of time units are reported through a same first report.

[0318] Optionally, as an implementation manner, the quantization result includes a second quantization reference value of each time unit (a maximum beam quality reporting value in each time unit), and a second differential value (a differential value between the second quantization reference value of the time unit and a beam quality reporting value of another beam in the corresponding time unit), in which implementation manner, the second quantization reference value of each time unit and the corresponding second differential value can be carried through a same first report.

[0319] Optionally, the first report can be carried through a CSI report.

[0320] Step 903: The terminal sends the first report to the base station.

[0321] Optionally, the first report includes the quantization result and the quantization information.

[0322] In this embodiment three, the terminal flexibly determines the quantization mode according to the prediction result, so that the quantization mode can match the prediction result in real time, and the problem that the first indication information cannot indicate the quantization mode with smaller reporting overhead or higher quantization precision because the information obtained by the base station is outdated and cannot match the change of the time-varying channel is solved.

[0323] Embodiment four:

[0324] As shown in FIG. 2, when the terminal reports the prediction results of multiple time units to the network, if the existing RSRP reporting method is used, each time unit includes a predicted RSRP maximum value and the difference between other beam qualities and the RSRP maximum value. Assuming that M is the number of predicted time units, the number of RSRPs reported in each time unit is Q. The total number of beams in a time unit is K.

[0325] As shown in FIG. 10a, the prediction of multiple time units each uses a respective second quantization reference value and a second difference value. The second difference value is the difference between the beam quality reporting value to be reported in each time unit and the second reference value of the time unit. The second quantization reference value is, for example, the maximum beam quality reporting value in each time unit.

[0326] The Q*M reporting values use the differential quantization method. The quantization method shown in FIG. 10a can be described as a single-differential quantization method for each time unit, and then:

[0327] The number of bits required for the beam quality reporting value to be reported is (B1+B2*(Q-1))*M; wherein B1 is the number of quantization bits required for the maximum beam quality reporting value, B1 is the quantization bit number of the first quantization reference value when the quantization information includes the first quantization reference value, B1 is the quantization bit number of the second quantization reference value when the quantization information does not include the first quantization reference value, for example, B1 is 7. B2 is the number of quantization bits required for the remaining beam quality reporting values other than the maximum beam quality reporting value, for example, B2 is 4.

[0328] The quantifiable difference range is 30dB;

[0329] The number of bits required for the CRI indication of multiple time units is log2(K)*Q*M;

[0330] As shown in FIG. 10b, if the prediction of M time units uses the quantization method of the first quantization reference value and the first difference value. The first difference value shown in FIG. 10b is the difference between the beam quality reporting value corresponding to the CRI reported in each time unit and the first quantization reference value. The first quantization reference value is the maximum value of the beam quality reporting value in the M time units.

[0331] Q*M report values adopt the differential quantization method, the quantization method shown in FIG. 10b can be described as single-differential quantization method of multiple time units, and then:

[0332] The bit number required by the beam quality report value to be reported is B1+B2*(M*Q-1).

[0333] The quantifiable differential range is 30 dB.

[0334] The bit number required by the CRI indication of multiple time units is log2(K)*Q*M.

[0335] The time domain position indication of the beam information corresponding to the first quantization reference value requires log2(M) bits. The time domain position indication can also be described as time instance indicator or occasion indicator. The time domain position indication can also be described as first quantization reference value time unit indication.

[0336] As shown in FIG. 10c, if the quantization method of multiple time units using the first quantization reference value, the first differential value and the second differential value is adopted. Among them, the second quantization reference value is represented by the first quantization reference value and the target first differential value, and the beam quality report value to be reported in the remaining time units is represented by the second quantization reference value and the second differential value.

[0337] Q*M report values adopt the differential quantization method, the quantization method shown in FIG. 10c can be described as double-differential quantization method of multiple time units, and then:

[0338] The bit number required by the beam quality report value to be reported is B1+B2*(M*Q-1).

[0339] The quantifiable differential range is 60 dB.

[0340] The bit number required by the CRI indication of multiple time units is log2(K)*Q*M. The time domain position indication of the beam information corresponding to the first quantization reference value requires log2(M) bits.

[0341] The bit number of the beam quality report value and the bit number of the CRI indication in FIG. 10a, FIG. 10b and FIG. 10c are shown in Table 3.

[0342] Table 3

[0343] Among them, the bit number difference between the differential methods of FIG. 10a and FIG. 10b is explained as follows:

[0344] (B1+B2*(Q-1))*M–(B1+B2*(M*Q-1)

[0345] = B1*M + B2*M(Q-1) - B1 - B2*(M*Q-1)

[0346] = B1*M + B2*M*Q - B2*M - B1 - B2*M*Q + B2

[0347] = B1*M - B2*M - B1 + B2

[0348] = (B1-B2)*(M-1)

[0349] Since B1>B2, when M>1, the quantization manner shown in Fig. 10b is advantageous to reduce the beam quality reporting value overhead (Table 3, first column).

[0350] When (B1-B2)*(M-1)-log2(M)>0, the scheme of Fig. 10b or 10c can make the total quantization result of the beam quality reporting value and the beam information indication have less bits than the scheme of Fig. 10a. Otherwise, the scheme corresponding to Fig. 10a makes the quantization result have less bits.

[0351] Since M is a positive integer, according to Table 4, when M>1, the scheme of Fig. 10b or 10c can make the quantization result have less bits than the scheme of Fig. 10a.

[0352] Table 4 (when B1=7, B2=4)

[0353] According to the above description, when M=1, the quantization bits required by the three schemes of Fig. 10a, 10b and 10c are the same; when M>1, the scheme of Fig. 10b or 10c can make the quantization result have less bits than the scheme of Fig. 10a, but when M>1, the scheme of Fig. 10c can make the indication range of the beam quality of multi-CRI expand by 2 times compared with the scheme of Fig. 10a or 10b.

[0354] When M=2, the scheme of Fig. 10b or 10c can make the quantization bits required by the scheme of Fig. 10a reduce by 2 bits, and as M increases, the scheme of Fig. 10b or 10c can make the quantization bits required by the scheme of Fig. 10a reduce more.

[0355] On the other hand, when M is larger, the channel correlation is weakened, and the change range of the beam quality to be reported in each time unit will be larger.

[0356] The scheme of the embodiment of the present application can achieve the purpose of flexibly determining the quantization reference value by determining the quantization reference value based on the beam quality reporting value of the M time units or the first indication information of the network side device, and then can select a quantization reference value with a smaller quantization proportion number to quantize the beam quality reporting value of the multiple time units, thereby facilitating saving the reporting overhead. In addition, the scheme of the embodiment of the present application can obtain higher quantization precision under the premise of reducing the reporting overhead, or can reduce the reporting overhead under the premise of meeting the quantization precision.
