[0021] The technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present disclosure and its application or use. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0022] The test method specified by the electromagnetic energy absorption index requirements (or SAR regulations) is based on the average power test over a period of time. The 3GPP standard generally believes that the terminal can achieve full time slot transmission at a transmission power of 23dBm, that is, FDD mode, which meets the SAR requirements and has no margin in the system design. When the terminal works in the NR (new radio) SA (standalone networking) highest power mode (+26dBm), the standard gives a default 50% (may change in actual application) uplink time share limit. In this way, the average power is equivalent to the FDD mode of 23dBm. Based on the above ideas, in the high-power carrier aggregation solution, by adjusting the uplink time share, that is, the proportion of the uplink time slot, the average transmission power of the terminal over a period of time can meet the electromagnetic energy absorption index requirements (or SAR regulations).

[0023] In addition, the base station needs to adjust the uplink time ratio of the terminal and schedule uplink resources, which requires the terminal's status. However, the current standard does not have any design for the interaction between the terminal and the base station in the high-power carrier aggregation scenario. Therefore, the subsequent plan will also focus on providing solutions for the design of the information format.

[0024] Figure 1 Flowcharts of some embodiments of the terminal capability indication method disclosed in the present invention. Figure 1 As shown, the method of this embodiment includes: steps S102 to S104.

[0025] In step S102, the terminal determines the maximum uplink time proportion supported when the transmit power of the carrier aggregation does not exceed the highest power level.

[0026] The power value corresponding to the highest power level in the current 3GPP standard is 26dBm. The case where the transmission power of carrier aggregation does not exceed the highest power level corresponds to the carrier aggregation scenario of Power Class 2 in the standard. The uplink time ratio is the proportion of the symbol time of uplink transmission scheduling within the preset evaluation time. The maximum uplink time ratio supported by the terminal can be pre-configured. This maximum uplink time ratio enables the average transmission power of the terminal within the preset time to meet the electromagnetic energy absorption index requirements or SAR regulations when the transmission power of carrier aggregation does not exceed the highest power level.

[0027] In step S104, the terminal sends capability indication information to the base station, so that the base station schedules uplink time slot resources of carriers of each frequency band in carrier aggregation according to the capability indication information.

[0028] The capability indication information includes the maximum uplink time ratio. The capability indication information may be sent to the base station via the BandCombinationList information element in the UE capability information elements.

[0029] First, the name of the capability indication information is designed. In some embodiments, the name of the capability indication information includes: a field indicating the maximum uplink time ratio, a field indicating the carrier aggregation scenario, and a field indicating the maximum power level. Through the design of the name of the capability indication information, it is possible to directly know which capability the capability indication information specifically indicates through the name.

[0030] In some embodiments, the name of the capability indication information is represented as:

[0031] maxUplinkDutyCycle-interBandCA-PC2,

[0032] maxUplinkDutyCycle-interBandCA-PC2-r17,

[0033] maxUplinkDutyCycle-CA-PC2, or,

[0034] maxUplinkDutyCycle-CA-FDD-TDD-PC2.

[0035] maxUplinkDutyCycle is a field indicating the maximum uplink time ratio, interBandCA indicates an inter-band carrier aggregation scenario, CA indicates a carrier aggregation scenario, PC2 indicates power class 2 (Power Class 2) which is the highest power level, and r17 indicates 3GPP release 17 (Release 17).

[0036] In the carrier aggregation scenario of Power Class 2, the power level of the carrier of each frequency band aggregated may be 23dBm or 26dBm. The four scenarios shown in the following Table 1 may be included.

[0037]

[0038]

[0039] For the above four scenarios, the content of the capability indication information of the terminal may be different. In some embodiments, the content of the capability indication information includes: a first field indicating the power level corresponding to the maximum transmit power of the carrier of each frequency band in the carrier aggregation, and a second field indicating the maximum uplink time proportion corresponding to the first field.

[0040] In some embodiments, the content of the capability indication information includes one or more of the following:

[0041] interBandCA-PC3-PC3-r17{x1},

[0042] interBandCA-PC3-PC2-r17{x2},

[0043] interBandCA-PC2-PC3-r17{x3}, and

[0044] interBandCA-PC2-PC2-r17{x4};

[0045] interBandCA-PC3-PC3-r17 indicates that the power level corresponding to the maximum transmit power of the carrier of each frequency band in inter-band carrier aggregation is power class 3 (Power Class 3, that is, the maximum transmit power of the carrier of each frequency band is 23dBm), interBandCA-PC3-PC2-r17 indicates that the power levels corresponding to the maximum transmit power of the carrier of each frequency band in inter-band carrier aggregation are power class 3 and power class 2 respectively, interBandCA-PC2-PC3-r17 indicates that the power levels corresponding to the maximum transmit power of the carrier of each frequency band in inter-band carrier aggregation are power class 2 and power class 3 respectively, interBandCA-PC2-PC2-r17 indicates that the power level corresponding to the maximum transmit power of the carrier of each frequency band in inter-band carrier aggregation is power class 2, and x1, x2, x3, and x4 respectively represent the maximum uplink time proportions corresponding to different first fields.

[0046] In some other embodiments, the content of the capability indication information includes one or more of the following:

[0047] interBandCA-Config0-r17{x1},

[0048] interBandCA-Config1-r17{x2},

[0049] interBandCA-Config2-r17{x3}, and

[0050] interBandCA-Config3-r17{x4};

[0051] interBandCA-Config0-r17, interBandCA-Config1-r17, interBandCA-Config2-r17, interBandCA-Config3-r17, respectively represent different combinations of power levels corresponding to the maximum transmit power of the carrier of each frequency band in inter-band carrier aggregation, and the different combinations include: the power level corresponding to the maximum transmit power of the carrier of each frequency band is power level 3, the power levels corresponding to the maximum transmit power of the carrier of each frequency band are power level 3 and power level 2 respectively, the power levels corresponding to the maximum transmit power of the carrier of each frequency band are power level 2 and power level 3 respectively, and the power level corresponding to the maximum transmit power of the carrier of each frequency band is power level 2, x1, x2, x3, x4 respectively represent the maximum uplink time proportions corresponding to different first fields.

[0052] When sending capability indication information, the terminal can selectively report the maximum uplink time percentage supported in one or more scenarios from the four scenarios according to the actual configuration. The design method of the name and content of the above capability indication information mainly considers the possible expression form defined in the standard. When actually transmitted at the bottom layer, the above content may be expressed in the form of coding, for example, x1, x2, x3, and x4 are specific values ​​or codes representing specific values.

[0053] Furthermore, the value ranges of x1, x2, x3, and x4 may include n50, n60, n70, n80, n90, and n100, which respectively indicate that the maximum uplink time accounts for 50%, 60%, 70%, 80%, 90%, and 100%. Therefore, the capability indication information may be defined to include 4 sequences, namely:

[0054] interBandCA-PC3-PC3-r17{n50,n60,n70,n80,n90,n100}

[0055] interBandCA-PC3-PC2-r17{n50,n60,n70,n80,n90,n100}

[0056] interBandCA-PC2-PC3-r17{n50,n60,n70,n80,n90,n100}

[0057] interBandCA-PC2-PC2-r17{n50,n60,n70,n80,n90,n100}

[0058] Or it can be expressed as:

[0059] interBandCA-Config0-r17{n50,n60,n70,n80,n90,n100}

[0060] interBandCA-Config1-r17{n50,n60,n70,n80,n90,n100}

[0061] interBandCA-Config2-r17{n50,n60,n70,n80,n90,n100}

[0062] interBandCA-Config3-r17{n50,n60,n70,n80,n90,n100}

[0063] The four sequences defined above list the possible forms of the content of the capability indication information reported by the terminal. In fact, the reporting time can select one or more of the four scenarios as in the above-mentioned embodiment, and the maximum uplink time proportion supported in each scenario is reported, and the reported maximum uplink time proportion makes the average transmission power of the terminal within the preset time meet the electromagnetic energy absorption index requirements or SAR regulations when the transmission power of the carrier aggregation does not exceed the maximum power level.

[0064] For example, the specific capability indication information reported by the terminal may be defined in the following form: maxUplinkDutyCycle-interBandCA-PC2-r17 SEQUENCE{

[0065] interBandCA-PC3-PC3-r17 ENUMERATED{n50,n60,n70,

[0066] n80,n90,n100}OPTIONAL,

[0067] interBandCA-PC3-PC2-r17 ENUMERATED{n50,n60,n70,

[0068] n80,n90,n100}OPTIONAL,

[0069] interBandCA-PC2-PC3-r17 ENUMERATED{n50,n60,n70,

[0070] n80,n90,n100}OPTIONAL,

[0071] interBandCA-PC2-PC2-r17 ENUMERATED{n50,n60,n70,

[0072] n80,n90,n100}OPTIONAL

[0073] }

[0074] After receiving the capability indication information of the terminal, the base station can schedule the uplink time slot resources of the carriers of each frequency band in the carrier aggregation to meet the maximum uplink time proportion. In some embodiments, the base station determines the uplink time proportion of the carriers of each frequency band in the carrier aggregation so that the uplink time proportion after the carrier aggregation does not exceed the maximum uplink time proportion in the capability indication information.

[0075] In some embodiments, the following formula is used to determine the uplink time proportion of the carriers of each frequency band in the carrier aggregation:

[0076]

[0077] Among them, P NR,x Indicates the maximum linear transmit power of the carrier in the new radio NR x band, P NR,y Indicates the maximum linear transmit power of the carrier in the new radio NR y band, P CA The maximum linear transmit power of carrier aggregation in bands x and y, respectively, Duty NR,x Indicates the uplink time ratio of the carrier in the x-band, Duty NR,y Indicates the uplink time ratio of the carrier in the y frequency band.

[0078] The base station can calculate the uplink time proportion of the carrier of each frequency band according to the above formula, and then schedule the resources of the carrier of each frequency band to meet the uplink time proportion of the carrier of each frequency band respectively.

[0079] In the method of the above embodiment, the terminal determines the maximum uplink time ratio supported when the transmission power of carrier aggregation does not exceed the maximum power level. The maximum uplink time ratio enables the average transmission power of the terminal within a preset time to meet the electromagnetic energy absorption index requirements or SAR regulations when the transmission power of carrier aggregation does not exceed the maximum power level. Then, the terminal sends the capability indication information including the maximum uplink time ratio to the base station, so that the base station learns the capability of the terminal, and schedules the uplink time slot resources of the carriers of each frequency band in the carrier aggregation according to the capability indication information, so that the terminal meets the electromagnetic energy absorption index requirements or SAR regulations when the transmission power of carrier aggregation does not exceed the maximum power level.

[0080] In the above embodiment, the terminal sends the maximum uplink time ratio supported by the terminal to the base station, and the maximum uplink time ratio is the overall maximum uplink time ratio of the aggregated carrier. In other embodiments, the terminal may send the maximum uplink time ratio of the carriers of each frequency band in the carrier aggregation to the base station. Figure 2 Give a description.

[0081] Figure 2 Flowcharts of other embodiments of the terminal capability indication method disclosed in the present invention. Figure 2 As shown, the method of this embodiment includes: steps S202 to S204.

[0082] In step S202, the terminal determines the maximum uplink time proportion of the carriers of each frequency band in the carrier aggregation when the transmit power of the carrier aggregation does not exceed the highest power level.

[0083] The maximum uplink time proportion of the carriers in each frequency band ensures that the average transmission power of the terminal within a preset time meets the electromagnetic energy absorption index requirements (or SAR regulations) when the transmission power of the carrier aggregation does not exceed the maximum power level.

[0084] In step S204, the terminal sends capability indication information to the base station, so that the base station schedules uplink time slot resources of carriers of each frequency band in carrier aggregation according to the capability indication information.

[0085] The capability indication information includes the maximum uplink time proportion of the carriers of each frequency band in the carrier aggregation. The capability indication information may be sent to the base station via the BandCombinationListinformation element in the UEcapability information elements.

Through the design of the name of the capability indication information, it is possible to directly know which capability the capability indication information specifically indicates through the name.

[0087] In some embodiments, the name of the capability indication information is represented as:

[0088] maxUplinkDutyCycle-interBandCA-PC2,

[0089] maxUplinkDutyCycle-interBandCA-PC2-r17,

[0090] maxUplinkDutyCycle-CA-PC2, or,

[0103] In some embodiments, the values ​​of y1, y2, y3, y4, y5, y6, and y7 are n20, n30, n35, n40, n60, n70, and n80, respectively, indicating that the maximum uplink time accounts for 20%, 30%, 35%, 40%, 60%, 70%, and 80%, respectively. The value ranges of z1, z2, z3, z4, z5, z6, and z7 include n20, n30, n40, n50, n60, n70, n80, n90, and n100, respectively, indicating that the maximum uplink time accounts for 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, and 100%, respectively. The specific values ​​of z1, z2, z3, z4, z5, z6, and z7 are determined by the power level corresponding to y1, y2, y3, y4, y5, y6, and y7 and the maximum transmission power of the carrier of each frequency band.

[0104] Since the terminal sends the maximum uplink time ratio of the carriers of each frequency band to the base station, the base station can directly schedule the uplink time slot resources of the carriers of each frequency band according to the maximum uplink time ratio of the carriers of each frequency band when performing scheduling.

[0105] In the method of the above embodiment, the terminal sends capability indication information including the maximum uplink time proportion of the carriers of each frequency band to the base station, so that the base station learns the capability of the terminal, and schedules the uplink time slot resources of the carriers of each frequency band in the carrier aggregation according to the capability indication information, so that the terminal meets the electromagnetic energy absorption index requirements or SAR regulations when the transmission power of the carrier aggregation does not exceed the maximum power level.
