For example, the terminal may report the modulation order and the maximum number of MIMO layers supported to the network device, but not the scaling factor, or the terminal may report the maximum number of MIMO layers supported to the network device, but not the scaling factor and the modulation order, or the terminal may not report the modulation order, the maximum number of MIMO layers, and the scaling factor to the network device. For the capability parameters not reported by the terminal, the network device may determine based on a preset condition, which may be, for example, the product of the modulation order, the maximum number of MIMO layers supported by the terminal, and the scaling factor should be ensured to meet a preset value. Optionally, when the terminal reports the modulation order and the maximum number of supported MIMO layers but does not report the scaling factor, the network device may determine that the scaling factor = preset value ÷ (modulation order × maximum number of MIMO layers); or, when the terminal reports the maximum number of MIMO layers but does not report the scaling factor and modulation order, the network device should determine the scaling factor and the modulation order so that the product of the scaling factor and the modulation order is equal to the preset value divided by the maximum number of MIMO layers; or, when the terminal does not report any of the above capability parameters, the network device may default the scaling factor to 1, and then determine the values ​​of the modulation order and the maximum number of MIMO layers based on preset conditions to ensure that the product of the modulation order, the maximum number of MIMO layers, and the scaling factor is the preset value; or, when the terminal does not report any of the above capability parameters, if the terminal is in the FR1 frequency band and the downlink supports 1024 quadrature amplitude modulation (Quadrature amplitude modulation) If the modulation order is 1024QAM, the default modulation order is 1024QAM. Otherwise, the default modulation order is 256QAM. After that, the scaling factor and the maximum number of MIMO layers are determined based on the preset conditions to ensure that the product of the modulation order, the maximum number of MIMO layers and the scaling factor is the preset value.

[0235] Optionally, in new versions (such as Rel-17 and Rel-18), Redcap terminals and eRedcap terminals are introduced. Since the capabilities of Redcap terminals, eRedcap terminals and normal terminals are different, the capability parameters supported by Redcap terminals and eRedcap terminals are also different from the capability parameters supported by normal terminals. Therefore, the "preset conditions for determining the unreported capability parameters of normal terminals" cannot be applied to determining the unreported capability parameters of Redcap terminals and eRedcap terminals. Therefore, a method for determining the unreported capability parameters of Redcap terminals and eRedcap terminals is urgently needed.

[0236] FIG2A is an interactive diagram illustrating a determination method according to an embodiment of the present disclosure. As shown in FIG2A , the embodiment of the present disclosure relates to a determination method for a communication system 100, the method comprising:

[0237] Step 2101: The second version terminal reports at least one of a first parameter, a second parameter, and a third parameter.

[0238] Optionally, in some embodiments, the second version may be, for example, the Rel-18 version. In this case, the second version terminal may be a RedCap terminal in the second version. For example, the second version terminal may be called a "Rel-18RedCap terminal", "eRedCap terminal", etc. This disclosure does not make any specific limitations.

[0239] Optionally, the second version terminal may report at least one of the first parameter, the second parameter, and the third parameter to the network device. The network device may receive at least one of the first parameter, the second parameter, and the third parameter reported by the second version terminal.

[0240] Optionally, the first parameter, the second parameter, and the third parameter may be used to calculate a downlink maximum data rate (peak data rate) of the second version terminal.

[0241] Optionally, in some embodiments, the second version terminal can be configured to report the first parameter, the second parameter and the third parameter, for example, it can be configured by the network device to report the first parameter, the second parameter and the third parameter, wherein the first parameter, the second parameter and the third parameter all correspond to a reporting type, and the reporting type may include mandatory reporting or optional reporting, wherein, when the reporting type of a parameter is mandatory reporting, it means that the parameter must be reported to the network device, and when the reporting type of a parameter is optional reporting, it means that the parameter can be optionally reported to the network device, for example, the parameter can be reported to the network device, or the parameter can be not reported to the network device.

[0242] In some embodiments, when the reporting type of the first parameter, the second parameter, and the third parameter is mandatory reporting, the first parameter, the second parameter, and the third parameter need to be reported by the second version terminal to the network device; or,

[0243] When the reporting type of at least one of the first parameter, the second parameter, and the third parameter is: optional reporting, at least one of the first parameter, the second parameter, and the third parameter will be reported by the second version terminal to the network device, or at least one of the first parameter, the second parameter, and the third parameter will not be reported by the second version terminal to the network device.

[0244] Optionally, the embodiment of FIG. 2A is based on the premise that "the reporting type of at least one of the first parameter, the second parameter, and the third parameter is optional reporting." Optionally, when the reporting type of at least one of the first parameter, the second parameter, and the third parameter is optional reporting, the second version terminal may report the first parameter, the second parameter, and the third parameter; or, the second version terminal may report any one or any two of the first parameter, the second parameter, and the third parameter; or, the second version terminal may not report the first parameter, the second parameter, and the third parameter.

[0245] Optionally, the first parameter may be, for example, a modulation order; the second parameter may be, for example, a maximum number of downlink MIMO layers supported by the second version terminal; and the third parameter may be, for example, a scaling factor.

[0246] Optionally, for the second version terminal, the value of the first parameter can be 1, 2, 4, 6 or 8, wherein when the value of the first parameter is 8, it indicates that the modulation order used in the maximum data rate calculation is 2. 8 =256QAM, when the value of the first parameter is 6, it means that the modulation order used in the maximum data rate calculation is 2 6 =64QAM.

[0247] Optionally, for the second version terminal, the value of the second parameter may be 1 or 2, that is, the maximum number of downlink MIMO layers supported by the second version terminal may be 1 or 2.

[0248] Optionally, for the second version terminal, the value of the third parameter may be 1, 0.8, 0.75 or 0.4, that is, the scaling factor of the second version terminal may be 1, 0.8, 0.75 or 0.4.

[0249] Optionally, in the embodiment of FIG. 2A , the above step 2101 may be optional and may be performed or not performed.

[0250] Step 2102: The network device determines at least one of the first parameter, the second parameter, and the third parameter.

[0251] Among them, when the second version terminal reports the first parameter, the second parameter, and the third parameter, the network device can directly determine the first parameter, the second parameter, and the third parameter based on the report of the second version terminal. When the second version terminal reports any one or any two of the first parameter, the second parameter, and the third parameter, the network device needs to determine the first parameter, the second parameter, and the third parameter that are not reported by the second version terminal; when the second version terminal does not report the first parameter, the second parameter, and the third parameter, the network device needs to determine the first parameter, the second parameter, and the third parameter.

[0252] Optionally, in some embodiments, when the network device determines at least one of the first parameter, the second parameter, and the third parameter (e.g., when the network device determines the first parameter, the second parameter, and the third parameter that is not reported by the second version terminal; or when the second version terminal does not report the first parameter, the second parameter, and the third parameter, the network device determines the first parameter, the second parameter, and the third parameter), the determination should be based on the first condition. Optionally, the first condition may be a condition that at least one of the first parameter, the second parameter, and the third parameter of the second version terminal must satisfy. Optionally, the first condition may include at least one of the following:

[0253] The second version terminal supports the first feature combination (FG), and the product of the first parameter, the second parameter, and the third parameter must equal the first value;

[0254] The second version terminal supports the second FG, and the product of the first parameter, the second parameter and the third parameter must be equal to the second value or the third value; wherein, when the maximum number of MIMO layers supported by the second version terminal is 1 layer, the product of the first parameter, the second parameter and the third parameter must be equal to the second value; when the maximum number of MIMO layers supported by the second version terminal is 2 layers, the product of the first parameter, the second parameter and the third parameter must be equal to the third value.

[0255] Optionally, the first FG may be FG 48 - 1 , the second FG may be FG 48 - 2 , the first value may be 3.2, the second value may be 0.75, and the third value may be 0.8.

[0256] Optionally, in some embodiments, when the second version terminal supports the first FG, when the network device determines at least one of the first parameter, the second parameter and the third parameter, it should ensure that the product of the first parameter, the second parameter and the third parameter finally determined is equal to the first value.

[0257] For example, when the second version terminal supports the first FG, the method for the network device to determine at least one of the first parameter, the second parameter, and the third parameter may include one or more of the following:

[0258] The second version terminal does not report the second parameter, and the default second parameter is 1;

[0259] The second version terminal does not report the first parameter. If the second parameter indicates that the maximum number of downlink MIMO layers supported by the second version terminal is 1, determining that the first parameter is 4 or 8;

[0260] The second version terminal does not report the third parameter. If the second parameter indicates that the maximum number of downlink MIMO layers supported by the second version terminal is 1, the third parameter is determined to be 0.8 or 0.4;

[0261] The second version terminal does not report the first parameter. If the second parameter indicates that the maximum number of downlink MIMO layers supported by the second version terminal is 2, and the third parameter reported by the second version terminal is 0.4, the first parameter is determined to be 4;

[0262] The second version terminal does not report the first parameter. If the second parameter indicates that the maximum number of downlink MIMO layers supported by the second version terminal is 2, and the third parameter reported by the second version terminal is 0.8, the first parameter is determined to be 2;

[0263] The second version terminal does not report the first parameter and the third parameter. If the second parameter indicates that the maximum number of downlink MIMO layers supported by the second version terminal is 2, the first parameter is determined to be 4 and the third parameter is determined to be 0.4. Alternatively, the first parameter is determined to be 2 and the third parameter is determined to be 0.8.

[0264] The second version terminal does not report the third parameter. If the second parameter indicates that the maximum number of downlink MIMO layers supported by the second version terminal is 2, and the first parameter reported by the second version terminal is 4, the third parameter is determined to be 0.4;

[0265] The second version terminal does not report the third parameter. If the second parameter indicates that the maximum number of downlink MIMO layers supported by the second version terminal is 2, and the first parameter reported by the second version terminal is 2, the third parameter is determined to be 0.8.

[0266] For example, in one embodiment, when the second version terminal supports the first FG, assuming that the second version terminal reports the second parameter as layer 1, but does not report the first parameter and the third parameter, the network device can determine based on the first condition that the first parameter is 4 and the third parameter is 0.8. In another embodiment, assuming that the second version terminal does not report the first parameter, the second parameter, and the third parameter, the network device can determine based on the first condition that the second parameter defaults to 1, and then can determine based on the first condition that the first parameter is 4 and the third parameter is 0.8. In yet another embodiment, assuming that the second version terminal reports the second parameter as layer 2 and the third parameter as 0.4, but does not report the first parameter, the network device can determine based on the first condition that the first parameter is 4.

[0267] Optionally, in other embodiments, when the second version terminal supports the second FG, the network device should ensure that the product of the first parameter, the second parameter and the third parameter is equal to the second value or the third value when determining at least one of the first parameter, the second parameter and the third parameter. When the maximum number of MIMO layers supported by the second version terminal is 1 layer, the product of the first parameter, the second parameter and the third parameter is equal to the second value; when the maximum number of MIMO layers supported by the second version terminal is 2 layers, the product of the first parameter, the second parameter and the third parameter is equal to the third value.

[0268] For example, when the second version terminal supports the second FG, the method in which the network determines at least one of the first parameter, the second parameter, and the third parameter may include one or more of the following:

[0269] The second version terminal does not report the first parameter, and determines that the first parameter is 1;

[0270] The second version terminal does not report the second parameter, and determines that the second parameter is 1;

[0271] The second version terminal does not report the third parameter. If the second parameter indicates that the maximum number of downlink MIMO layers supported by the second version terminal is 1, the third parameter is determined to be 0.75.

[0272] The second version terminal does not report the third parameter. If the second parameter indicates that the maximum number of downlink MIMO layers supported by the second version terminal is 2, the third parameter is determined to be 0.4.

[0273] For example, in one embodiment, when the second version terminal supports the second FG, assuming that the second version terminal reports the second parameter as layer 1 but does not report the first parameter and the third parameter, the network device can determine, based on the first condition, that the first parameter is 1 and the third parameter is 0.75. In another embodiment, assuming that the second version terminal reports the second parameter as layer 2 but does not report the first parameter and the third parameter, the network device can determine, based on the first condition, that the first parameter is 1 and the third parameter is 0.4. In yet another embodiment, assuming that the second version terminal does not report the first parameter, the second parameter, and the third parameter, the network device can determine, based on the first condition, that the first parameter is 1, the second parameter is layer 1, and the third parameter is 0.75.

[0274] Step 2103: The network device calculates the maximum downlink data rate of the second version terminal based on the determined first parameter, second parameter, and third parameter.

[0275] Optionally, the network device may calculate the maximum downlink data rate of the second version terminal based on the parameters reported by the second version terminal in step 2101 and / or the parameters determined in step 2102. For example, assume that in step 2101, the second version terminal reports the second parameter as layer 1, but does not report the first parameter and the third parameter. Simultaneously, in step 2102, the network device determines based on the first condition that the first parameter is 4 and the third parameter is 0.8. The network device may calculate the maximum downlink data rate of the second version terminal based on the first parameter being 4, the second parameter being layer 1, and the third parameter being 0.8.

[0276] Step 2104: The network device schedules downlink resources for the second version terminal based on the maximum downlink data rate of the second version terminal.

[0277] The determination method involved in the embodiments of the present disclosure may include at least one of steps S2101 to S2104. For example, step S2101 may be implemented as an independent embodiment, step S2102 may be implemented as an independent embodiment, step S2103 may be implemented as an independent embodiment, and steps S2101+S2102 may be implemented as independent embodiments, but are not limited thereto.

[0278] In this embodiment or example, unless there is any contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other embodiments or other examples.

[0291] The first version terminal does not report the first parameter and directly determines that the first parameter is 64QAM.

[0307] FIG2D is an interactive diagram illustrating a determination method according to an embodiment of the present disclosure. As shown in FIG2D , the embodiment of the present disclosure relates to a determination method for use in a communication system 100, the method comprising:

[0308] Step 2401: The second version terminal reports at least one of the fourth parameter, the fifth parameter, and the sixth parameter.

[0309] Optionally, for a detailed introduction to the second version, refer to the above embodiment description.

[0310] Optionally, the second version terminal may report at least one of the fourth parameter, the fifth parameter, and the sixth parameter to the network device. The network device may receive at least one of the fourth parameter, the fifth parameter, and the sixth parameter reported by the second version terminal.

[0311] Optionally, the fourth parameter, the fifth parameter, and the sixth parameter may be used to calculate an uplink maximum data rate (peak data rate) of the second version terminal.

[0312] Optionally, in some embodiments, the second version terminal can be configured to report the fourth parameter, the fifth parameter and the sixth parameter, for example, it can be configured by the network device to report the fourth parameter, the fifth parameter and the sixth parameter, wherein the fourth parameter, the fifth parameter and the sixth parameter all correspond to a reporting type, and the reporting type may include mandatory reporting or optional reporting, wherein, when the reporting type of a parameter is mandatory reporting, it means that the parameter must be reported to the network device, and when the reporting type of a parameter is optional reporting, it means that the parameter can be optionally reported to the network device, for example, the parameter can be reported to the network device, or the parameter can be not reported to the network device.

[0313] In some embodiments, when the reporting type of the fourth parameter, the fifth parameter, and the sixth parameter is mandatory reporting, the fourth parameter, the fifth parameter, and the sixth parameter need to be reported by the second version terminal to the network device; or,

[0314] When the reporting type of at least one of the fourth parameter, the fifth parameter, and the sixth parameter is: optional reporting, at least one of the fourth parameter, the fifth parameter, and the sixth parameter will be reported by the second version terminal to the network device, or at least one of the fourth parameter, the fifth parameter, and the sixth parameter will not be reported by the second version terminal to the network device.

[0315] Optionally, the embodiment of FIG. 2D is based on the premise that "the reporting type of at least one of the fourth parameter, the fifth parameter, and the sixth parameter is optional reporting." Optionally, when the reporting type of at least one of the fourth parameter, the fifth parameter, and the sixth parameter is optional reporting, the second version terminal may report the fourth parameter, the fifth parameter, and the sixth parameter; or, the second version terminal may report any one or any two of the fourth parameter, the fifth parameter, and the sixth parameter; or, the second version terminal may not report the fourth parameter, the fifth parameter, and the sixth parameter.

[0316] Optionally, the fourth parameter may be, for example, a modulation order; the fifth parameter may be, for example, a maximum number of uplink MIMO layers supported by the second version terminal; and the sixth parameter may be, for example, a scaling factor.

[0317] Optionally, for the second version terminal, the value of the fourth parameter can be 1, 2, 4, 6 or 8, wherein when the value of the fourth parameter is 8, it indicates that the modulation order used in the maximum data rate calculation is 2. 8 =256QAM, when the value of the fourth parameter is 6, it means that the modulation order used in the maximum data rate calculation is 2 6 =64QAM.

[0318] Optionally, for the second version terminal, the value of the fifth parameter can be 1 or 2. It should be noted that the fifth parameter is the maximum number of uplink MIMO layers supported by the terminal, wherein, for the second version terminal, the maximum number of uplink MIMO layers supported by it will not actually be 2 layers, that is, if the second version terminal reports the fifth parameter, the fifth parameter reported by the second version terminal will only be 1, not 2. However, in the present disclosure, the value of the fifth parameter can be set to 2. When the second version terminal does not report the fifth parameter, the network device can optionally consider that the value of the fifth parameter used for calculating the uplink maximum data rate in the second version is 2. At this time, the value of the fifth parameter is 2 only means: when calculating the uplink maximum data rate in the second version, the calculation is based on "the maximum number of uplink MIMO layers supported by the second version terminal is 2", and does not mean: the maximum number of uplink MIMO layers actually supported by the second version terminal is 2.

[0319] Optionally, for the second version terminal, the value of the sixth parameter may be 1, 0.8, 0.75 or 0.4, that is, the scaling factor of the second version terminal may be 1, 0.8, 0.75 or 0.4.

[0320] Optionally, in the embodiment of FIG. 2D , the above step 2401 may be optional and may be performed or not performed.

[0321] Step 2402: The network device determines at least one of the fourth parameter, the fifth parameter, and the sixth parameter.

[0322] Among them, when the second version terminal reports the fourth parameter, the fifth parameter, and the sixth parameter, the network device can directly determine the fourth parameter, the fifth parameter, and the sixth parameter based on the report of the second version terminal. When the second version terminal reports any one or any two of the fourth parameter, the fifth parameter, and the sixth parameter, the network device needs to determine the parameters of the fourth parameter, the fifth parameter, and the sixth parameter that are not reported by the second version terminal; when the second version terminal does not report the fourth parameter, the fifth parameter, and the sixth parameter, the network device needs to determine the fourth parameter, the fifth parameter, and the sixth parameter.

[0323] Optionally, in some embodiments, the network device may first determine the fifth parameter.

[0536] The determination method involved in the embodiment of the present disclosure may include at least one of steps S5101 to S5107. For example, step S5101 may be implemented as an independent embodiment, and step S5102 may be implemented as an independent embodiment, but the present invention is not limited thereto.

[0537] In this embodiment or example, unless there is any contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other embodiments or other examples.

[0538] The following is an exemplary introduction to the above method.

[0539] Method 1: For the eRedCap terminal, it is mandatory to report Q (the first parameter mentioned above), v (the third parameter mentioned above) and f (the second parameter mentioned above)

[0540] This method is valid for one or more of the following features: FG 48-1, FG 48-2

[0541] Method 2: For eRedCap terminals, the reporting type of Q, v, and f is optional.

[0542] Furthermore, for FG 48-1 and FG 48-2, redefine the default values ​​of the eRedCap terminal data rate related parameters by one or more of the following methods:

[0543] FG 48-1 (3.2: 1,0.8,0.75,0.4; 1,2; 1,2,4,6,8)

[0544] 0.4,1,8; 0.8,1,4; 0.4,2,4; 0.8,2,2

[0545] When the terminal does not report the modulation order, the value of the modulation order corresponding to the maximum data rate calculation is determined based on the parameters v and f.

[0546] When the terminal supports MIMO layer 1, the modulation order value is 4

[0547] This method is also applicable to uplink and downlink

[0548] When the terminal supports MIMO layer 2, the modulation order value is further determined by the scaling factor value:

[0549] When the reported scaling factor is 0.4, the default modulation order value is 4; when the reported scaling factor is 0.8, the default modulation order value is 2.

[0550] When the terminal also does not report the scaling factor, the scaling factor and the modulation order are set to one of (0.4, 4) and (0.8, 2).

[0551] This method is only applicable to downlink transmission

[0552] When the terminal does not report the maximum MIMO layer, the default value is 1

[0553] Method 2

[0554] FG 48-1

[0555] When the terminal supports MIMO layer 1, the default modulation order value is 0.8

[0556] This method is also applicable to uplink and downlink

[0557] When the terminal supports MIMO layer 2, the scaling factor value is further determined by the modulation order value:

[0558] When the reported modulation order value is 4, the scaling factor defaults to 0.4; when the reported modulation order value is 2, the scaling factor defaults to 0.8.

[0559] When the terminal also does not report the scaling factor, the scaling factor and the modulation order can be either (0.4, 4) or (0.8, 2).

[0560] This method is only applicable to Downlink

[0561] FG 48-2

[0562] When the terminal does not report the modulation order, the modulation order corresponding to the maximum data rate calculation is 1

[0563] When the terminal does not report the maximum MIMO layer it supports, the default value is 1

[0564] When a terminal does not report a scaling factor, its default value is determined by the maximum MIMO layer it supports:

[0565] When the maximum MIMO layer supported by the terminal is 1, the default value is 0.75; when the maximum MIMO layer supported by the terminal is 2, the default value is 0.8

[0566] The above method is also applicable to the calculation of uplink and downlink data rates.

[0567] other

[0568] For Rel-17 RedCap terminals, redefine the default values ​​for modulation order reporting.

[0569] For FR1 band, when the terminal does not report supportedModulationOrderDL, if it reports that DL supports 256QAM, the modulation order used for maximum data rate calculation is 256QAM; otherwise, it is 64QAM.

[0570] The present disclosure proposes a method for determining default values ​​of parameters related to peak data rate calculation, clarifies the eRedCap terminal capability reporting behavior, and avoids ambiguity in the determination of peak rate between the base station and the eRedCap terminal.
