[0018] In the embodiments of the present invention, terms such as "exemplary" or "for example" are used to represent by way of example, illustration, or explanation. Any embodiment or design solution described as "exemplary" or "for example" in the embodiments of the present invention should not be construed as being more preferable or having more advantages than other embodiments or design solutions. To be precise, the use of terms such as "exemplary" or "for example" is intended to show related concepts in a specific manner.
[0019] Before elaborating on the technical solutions of the embodiments of the present invention, first, a solution for realizing coverage expansion by a high-power terminal and related solutions for terminal capability parameter reporting will be briefly introduced.
[0020] In the design of the solution for realizing coverage expansion by a high-power terminal, generally, the control of the uplink duty cycle is adopted, and the uplink duty cycle is shortened, that is, UL Dutycycle < 100%, so that during the effective data transmission period, high power is used for transmission to realize coverage expansion, while ensuring that the overall radiation of the terminal (for example, Specific Absorption Rate (SAR)) statistically calculated over a certain relatively long period (for example, 6 minutes, which is often used for device authentication) does not exceed the reference value. For example, as shown in FIG. 1, in the first case, the terminal transmits with a transmit power of 23 dBm and UL Dutycycle = 100%, and in the second case, the terminal transmits with a transmit power of 26 dBm and UL Dutycycle = 50%. In such two cases, the radiation effects statistically calculated over a relatively long period (for example, 6 minutes) are similar, but in the second case, the terminal can adopt a relatively large transmit power (for example, 26 dBm) during the effective data transmission period to realize coverage expansion.
[0021] Under the condition of ensuring that the overall radiation does not exceed the reference value, at a specific power level, the uplink duty cycle supported by different high-power terminals is different (for example, the UL Duty Cycle may be from 10% to 100%). This value is a terminal capability parameter and needs to be reported to the network-side device for reference in the uplink scheduling by the network-side device and the operation of the terminal.
[0022] For a 5G SA single-connection time division duplex (TDD) terminal, currently in the 3GPP standard, the maximum uplink duty cycle (maxUplinkDutyCycle) is defined, which indicates the maximum capability of the uplink duty cycle UL Duty Cycle when the high-power terminal adopts a transmission power of 26 dBm.
[0023] For a terminal with multiple connection links in the uplink, since the radiation is the overall effect of multiple connections, it is necessary to evaluate the combination formed by multiple connections to ensure that the overall does not exceed the total radiation threshold. For example, it is necessary to ensure that duty1×Tx_power1 + duty2×Tx_power2 + … ≦ the limit value. Taking the 5G ENDC LTE TDD + NR TDD dual-connection terminal as an example, currently, the 3GPP standard, based on the specific network uplink and downlink slot ratio configuration of LTE, uses the maximum UL Dutycycle corresponding to LTE TDD at the time of this uplink and downlink slot ratio configuration as a reference, and based on this, defines the maximum uplink duty cycle maxUplinkDutyCycle of the high-power terminal that the NR link can support as the terminal capability for reference in the uplink scheduling by the network-side device and the operation of the terminal. For example, LTE_TDD_max_UL_dutycycle×LTE_Tx_power +maxUplinkDutyCycle×NR_Tx_power≦the limit value is true.
[0024] The above limit value may be determined based on the total radiation threshold value and the implementation solution of the terminal (for example, the technical performance parameters of the terminal), and the limit values corresponding to different terminals may be different.
[0025] For a dual-connection terminal including an FDD link, the theoretical range of the uplink duty cycle UL Dutycycle of the FDD mode is 0 to 100%, and since the dynamic range is relatively large, it causes the inability to determine the capability parameters of another link in the uplink dual-connection scenario. As a result, the reporting of the overall capability of the terminal and the uplink scheduling of the network-side device lack a reference basis.
[0026] In view of this, to solve the above problems, embodiments of the present invention provide a method for determining capability parameters, an uplink scheduling method, a terminal, and a network-side device.
[0027] Hereinafter, embodiments of the present invention will be introduced while combining the accompanying drawings. The embodiments according to the present invention can be used in a wireless communication system. This wireless communication system may be a 5G system, or an evolved long term evolution (eLTE) system, or a subsequent evolved communication system.
[0028] FIG. 2 is a structural diagram of a network system according to an embodiment of the present invention. As shown in FIG. 2, it includes a terminal 21, a first network-side device 22, and a second network-side device 23. The terminal 21 is a dual-connection terminal that is simultaneously connected to the first network-side device 22 and the second network-side device 23. The connection link of the terminal 21 includes a first link and a second link. The first link is an FDD link. The terminal 21 may be a mobile communication device, for example, a mobile phone, a tablet personal computer, a laptop computer, a personal digital assistant (abbreviated as PDA), a mobile Internet device (MID), or a wearable device, etc. In addition, in the embodiment of the present invention, the specific type of the terminal 21 is not limited. The above first network-side device 22 and second network-side device 23 may physically be different devices, or may be the same device. The above first network-side device 22 and second network-side device 23 may be 5G network-side devices (for example, gNB, 5G NR NB), or may be 4G network-side devices (for example, eNB), or may be 3G network-side devices (for example, NB), or may be network-side devices in a subsequent evolved communication system, etc. In addition, in the embodiment of the present invention, the specific types of the first network-side device 22 and the second network-side device 23 are not limited.
[0029] FIG. 3 is a flowchart of a method for determining capability parameters according to an embodiment of the present invention. As shown in FIG. 3, the method for determining capability parameters is used for a terminal. The connection link of the terminal includes a first link and a second link. The first link is a frequency division duplex FDD link. This method includes the following steps.
[0030] Step 301: Determine the second maximum uplink duty cycle of the terminal at the second maximum transmission power based on the first maximum transmission power and the first maximum uplink duty cycle.
[0031] Both the first maximum transmission power and the first maximum uplink duty cycle are terminal capability parameters at the first link, and the first maximum uplink duty cycle is a predefined capability parameter. Both the second maximum transmission power and the second maximum uplink duty cycle are terminal capability parameters at the second link.
[0032] In an embodiment of the present invention, by predefining the maximum uplink duty cycle of the first link, that is, the FDD link (i.e., the first maximum uplink duty cycle), the uplink duty cycle of the FDD link, which originally has a relatively large dynamic range, is clarified. Thereby, based on the maximum uplink duty cycle and the maximum transmission power of the first link (i.e., the first maximum transmission power), the terminal can determine the maximum uplink duty cycle (i.e., the second maximum uplink duty cycle) that the terminal can support at a certain maximum transmission power of the second link (i.e., the second maximum transmission power). In this way, a reference basis can be provided for aspects such as the reporting of the overall terminal capability parameters, the uplink scheduling behavior of the network-side device, and the uplink transmission behavior of the terminal, which is beneficial to improving the communication performance in the uplink dual-connection scenario.
[0033] Optionally, the method further includes reporting the second maximum uplink duty cycle.
[0034] After the terminal determines the capability parameters of the second link, the terminal can report to the network-side device at an appropriate timing the capability parameters of the terminal on the second link, that is, the second maximum uplink duty cycle of the terminal at the second maximum transmission power. In this way, after receiving the capability parameters of the terminal on the second link, the network-side device can perform uplink scheduling for the terminal with reference to the capability parameters of the terminal on the second link.
[0035] The timing at which the terminal reports the second maximum uplink duty cycle may be when the terminal starts up for the first time, or any appropriate timing among subsequent timings.
[0036] The above-mentioned second link may be an FDD link or a TDD link.
[0037] The above-mentioned first maximum uplink duty cycle is a predefined capability parameter. When defining the first maximum uplink duty cycle in advance, the first maximum uplink duty cycle may be determined based on the technical performance parameters of the terminal, or the determination of the first maximum uplink duty cycle may be realized in a manner agreed upon by the protocol.
[0038] Accordingly, the above-mentioned first maximum transmission power and the second maximum transmission power may be determined based on the technical performance parameters of the terminal, or may be determined in a manner agreed upon by the protocol.
[0039] As described above, for a terminal in which the uplink includes multiple connection links, since the radiation is the overall effect of multiple connections, it is necessary to evaluate the combination formed by the multiple connections to ensure that the whole does not exceed the total radiation threshold.
[0040] In view of this, in an embodiment of the present invention, for a terminal including a first link and a second link, the total radiation generated by the two links should not exceed the total radiation threshold. Therefore, when determining the second maximum uplink duty cycle of the terminal at the second maximum transmission power, the first maximum transmission power, the first maximum uplink duty cycle, and the total radiation threshold can be combined to determine the second maximum uplink duty cycle of the terminal at the second maximum transmission power.
[0041] That is, determining the second maximum uplink duty cycle of the terminal at the second maximum transmission power based on the first maximum transmission power and the first maximum uplink duty cycle includes determining the second maximum uplink duty cycle of the terminal at the second maximum transmission power based on the first maximum transmission power, the first maximum uplink duty cycle, and the total radiation threshold.
[0042] The product of the first maximum transmission power × the first maximum uplink duty cycle + the second maximum transmission power × the second maximum uplink duty cycle ≤ the limit value.
[0043] The above limit value may be determined based on the total radiation threshold and the implementation solution of the terminal (for example, the technical performance parameters of the terminal), and the limit values corresponding to different terminals may be different.
[0044] In this embodiment, by combining the first maximum transmission power, the first maximum uplink duty cycle, and the total radiation threshold to determine the second maximum uplink duty cycle of the terminal at the second maximum transmission power, the determined second maximum uplink duty cycle of the terminal at the second maximum transmission power is made more reasonable and has a higher reference value.
[0045] The method for determining the capability parameter according to the embodiment of the present invention is simple and feasible, and is applicable to various scenarios that require realizing a high-power terminal for uplink dual connection, such as E-UTRA / NR Dual Connectivity (ENDC) including FDD links, uplink carrier aggregation, and Supplementary uplink (SUL).
[0046] The method for determining the capability parameter according to the embodiment of the present invention is 4G FDD-TDD dual connection ENDC, 5G FDD-TDD dual connection ENDC, 4G FDD-FDD dual connection ENDC, 5G FDD-FDD dual connection ENDC, 5G FDD-TDD uplink carrier aggregation, 5G FDD-FDD uplink carrier aggregation, 4G FDD-TDD uplink carrier aggregation, 4G FDD-FDD uplink carrier aggregation, 5G FDD-TDD SUL, and is applicable to at least one of the scenarios of 5G FDD-FDD SUL.
[0047] Optionally, the method further includes when the uplink duty cycle scheduled by the network-side device on the first link is less than or equal to the first maximum uplink duty cycle, and the uplink duty cycle scheduled by the network-side device on the second link is less than or equal to the second maximum uplink duty cycle, the terminal performs uplink transmission on the first link with the first transmission power and performs uplink transmission on the second link with the second transmission power, wherein the first transmission power is less than or equal to the first maximum transmission power, The second transmission power is less than or equal to the second maximum transmission power.
[0048] That is, if the uplink transmission scheduled by the network-side device is within the high-power capability range of the terminal, that is, the uplink duty cycle of the first link scheduled by the network-side device is less than or equal to the first maximum uplink duty cycle, and the uplink duty cycle of the second link scheduled by the network-side device is less than or equal to the second maximum uplink duty cycle, each link of the terminal can perform uplink transmission according to the maximum transmission power.
[0049] Note that when the uplink transmission scheduled by the network-side device is within the high-power capability range of the terminal, each link of the terminal does not necessarily perform uplink transmission according to the maximum transmission power, and may perform uplink transmission according to a transmission power smaller than the maximum transmission power, and the embodiments of the present invention do not limit this.
[0050] Optionally, the method further includes if the uplink duty cycle scheduled by the network-side device on the first link is greater than the first maximum uplink duty cycle, or the uplink duty cycle scheduled by the network-side device on the second link is greater than the second maximum uplink duty cycle, the terminal further performs uplink transmission on the first link with a third transmission power and performs uplink transmission on the second link with a fourth transmission power, wherein the third transmission power is less than the first maximum transmission power, and / or the fourth transmission power is less than the second maximum transmission power.
[0051] That is, the uplink transmission scheduled by the network-side device exceeds the high-power capability range of the terminal. That is, the uplink duty cycle of the first link scheduled by the network-side device is greater than the first maximum uplink duty cycle, or the uplink duty cycle of the second link scheduled by the network-side device is greater than the second maximum uplink duty cycle. In this case, the terminal cannot perform uplink transmission according to the first maximum transmission power and the second maximum transmission power simultaneously, and needs to perform a certain power backoff. That is, to ensure that the overall radiation does not exceed the reference value, one or all links of the terminal perform uplink transmission according to a transmission power smaller than the maximum transmission power. For example, the first link of the terminal performs uplink transmission according to a transmission power smaller than the first maximum transmission power, or the second link of the terminal performs uplink transmission according to a transmission power smaller than the second maximum transmission power, or the first link of the terminal performs uplink transmission according to a transmission power smaller than the first maximum transmission power, and the second link performs uplink transmission according to a transmission power smaller than the second maximum transmission power.
[0052] Hereinafter, a specific method for determining the second maximum uplink duty cycle at the second maximum transmission power by the terminal will be described by way of example.
[0053] For an ENDC dual-connection terminal, assume that Plte represents the maximum transmission power of the LTE link, Pnr represents the maximum transmission power of the NR link, and Ptotal represents the total maximum transmission power. DutyLTE represents the uplink duty cycle of the LTE link. DutyNR represents the uplink duty cycle of the NR link.
[0054] Example 1: For a high-power terminal configuration with Plte = 23 dBm, Pnr = 23 dBm, and Ptotal = 26 dBm, for example, DutyLTE = 70% and Plte = 23 dBm are adopted as the reference configuration for the LTE FDD link. Based on this reference configuration, the maximum uplink duty cycle capacity maxUplinkDutyCycle of the NR link is reported. That is, the terminal can achieve that the overall radiation (e.g., specific absorption rate SAR) does not exceed the reference value in the scenario of DutyLTE = 70%, Plte = 23 dBm, DutyNR = maxUplinkDutyCycle, Pnr = 23 dBm, and Ptotal = 26 dBm, that is, the overall radiation is below the total radiation threshold. In an embodiment of the present invention, in order to ensure that the overall radiation of the terminal on each link is below the total radiation threshold, the limit value may be determined based on the total radiation threshold and the implementation solution of the terminal (e.g., the technical performance parameters of the terminal). That is, (DutyLTE = 70%) × (LTE_Tx_power = 23 dBm) + maxUplinkDutyCycle × (NR_Tx_power = 23 dBm) ≤ limit value is satisfied.
[0055] In this case, the network-side device can schedule the terminal to perform uplink transmission in the manner of DutyLTE ≤ 70%, Plte ≤ 23 dBm, DutyNR ≤ maxUplinkDutyCycle, Pnr ≤ 23 dBm, and Ptotal ≤ 26 dBm. If DutyLTE > 70% or DutyNR > maxUplinkDutyCycle scheduled by the network-side device, in order to ensure that the overall radiation does not exceed the reference value, one or all links of the terminal need to perform a certain power back-off, that is, the maximum transmission power of Plte = 23 dBm, Pnr = 23 dBm, and Ptotal = 26 dBm cannot be reached.
[0056] Example 2: For a high-power terminal configuration with Plte = 23 dBm, Pnr = 26 dBm, and Ptotal = 26 dBm, for example, DutyLTE = 40% and Plte = 23 dBm are adopted as the reference configuration for the LTE FDD link. Based on this reference configuration, the maximum uplink duty cycle maxUplinkDutyCycle of the NR link is reported. That is, the terminal can achieve that the overall radiation (e.g., specific absorption rate SAR) does not exceed the reference value in the scenario of DutyLTE = 40%, Plte = 23 dBm, DutyNR = maxUplinkDutyCycle, Pnr = 26 dBm, and Ptotal = 26 dBm, that is, the overall radiation is below the total radiation threshold. In an embodiment of the present invention, in order to ensure that the overall radiation of the terminal on each link is below the total radiation threshold, a limit value may be determined based on the total radiation threshold and the implementation solution of the terminal (e.g., the technical performance parameters of the terminal). That is, (DutyLTE = 40%) × (LTE_Tx_power = 23 dBm) + maxUplinkDutyCycle × (NR_Tx_power = 26 dBm) ≤ limit value That is.
[0057] In this case, the network-side device can schedule the terminal to perform uplink transmission in the manner of DutyLTE ≤ 40%, Plte ≤ 23 dBm, DutyNR ≤ maxUplinkDutyCycle, Pnr ≤ 26 dBm, and Ptotal ≤ 26 dBm. If DutyLTE > 40% or DutyNR > maxUplinkDutyCycle scheduled by the network-side device, in order to ensure that the overall radiation does not exceed the reference value, one or all links of the terminal perform a certain power back-off, that is, the maximum transmission power of Plte = 23 dBm, Pnr = 26 dBm, and Ptotal = 26 dBm cannot be reached.
[0058] In an embodiment of the present invention, a reference configuration of the capability parameters of a group of first links may be predefined, for example, DutyLTE = 70%, Plte = 23 dBm or DutyLTE = 40%, Plte = 23 dBm. A plurality of reference configurations of the capability parameters of the first links may be predefined. Accordingly, the terminal may determine a plurality of combinations of the capability parameters on the second link. For example, if a reference configuration of the capability parameters of two groups of first links {DutyLTE1, Plte1; DutyLTE2, Plte2} is predefined, the maximum uplink duty cycle capabilities maxUplinkDutyCycle of the terminal at one maximum transmit power of the second link are also two types, that is, {maxUplinkDutyCycle1, maxUplinkDutyCycle2}. In this way, since the capability parameters of the terminal on the first link and the second link have multiple types of combinations, the network-side device can more flexibly perform uplink scheduling on the terminal according to multiple types of combinations of the capability parameters.
[0059] That is, the capability parameters of the terminal on the first link include N groups, and the capability parameters of each group respectively include a first maximum transmit power and a first maximum uplink duty cycle, where N is an integer greater than 1. Determining the second maximum uplink duty cycle of the terminal at the second maximum transmit power based on the first maximum transmit power and the first maximum uplink duty cycle is including respectively determining the second maximum uplink duty cycle of the terminal at the second maximum transmit power based on the first maximum transmit power and the first maximum uplink duty cycle in the capability parameters of each group.
[0060] Hereinafter, taking an example, a specific method for the terminal to determine the capability parameters on the second link when the reference configuration of the capability parameters of the terminal on the first link has multiple types of combinations will be described.
[0061] For example, for the case of Plte = 23 dBm, Pnr = 23 dBm, and Ptotal = 26 dBm, the LTE FDD reference configuration {DutyLTE1 = 70%, Plte1 = 23 dBm; DutyLTE2 = 40%, Plte2 = 23 dBm} may be adopted. When Pnr = 23 dBm and Ptotal = 26 dBm, the maximum uplink duty cycle capabilities of the NR link that ensure the total radiation does not exceed the reference value are {maxUplinkDutyCycle1, maxUplinkDutyCycle2}. That is, (DutyLTE = 70%) × (LTE_Tx_power = 23 dBm) + maxUplinkDutyCycle1 × (NR_Tx_power = 23 dBm) ≤ limit value And, (DutyLTE = 40%) × (LTE_Tx_power = 23 dBm) + maxUplinkDutyCycle2 × (NR_Tx_power = 23 dBm) ≤ limit value That is.
[0062] In such cases, the terminal has the ability to ensure that the total radiation does not exceed the reference value in both of the two scenarios of DutyLTE ≤ 70%, PLTE ≤ 23 dBm, DutyNR ≤ maxUplinkDutyCycle1, Pnr ≤ 23 dBm, Ptotal ≤ 26 dBm and DutyLTE ≤ 40%, PLTE ≤ 23 dBm, DutyNR ≤ maxUplinkDutyCycle2, Pnr ≤ 23 dBm, Ptotal ≤ 26 dBm, indicating that the network-side device can perform corresponding uplink scheduling for the terminal. When the network scheduling exceeds the above capabilities, the terminal performs power back-off.
[0063] For example, for the case of Plte = 23 dBm, Pnr = 26 dBm, and Ptotal = 26 dBm, an LTE FDD reference configuration {DutyLTE1 = 40%, PLTE1 = 23 dBm; DutyLTE2 = 20%, PLTE2 = 23 dBm} may be adopted. When Pnr = 26 dBm and Ptotal = 26 dBm, the maximum uplink duty cycle capabilities of the NR link that ensure the overall radiation does not exceed the reference value are {maxUplinkDutyCycle1, maxUplinkDutyCycle2}. That is, (DutyLTE = 40%) × (LTE_Tx_power = 23 dBm) + maxUplinkDutyCycle1 × (NR_Tx_power = 26 dBm) ≤ limit value And, (DutyLTE = 20%) × (LTE_Tx_power = 23 dBm) + maxUplinkDutyCycle2 × (NR_Tx_power = 26 dBm) ≤ limit value.
[0064] Such cases mean that in both of the two scenarios where the terminal has DutyLTE ≤ 40%, PLTE ≤ 23 dBm, DutyNR ≤ maxUplinkDutyCycle1, Pnr ≤ 26 dBm, and Ptotal ≤ 26 dBm, and DutyLTE ≤ 20%, PLTE ≤ 23 dBm, DutyNR ≤ maxUplinkDutyCycle2, Pnr ≤ 26 dBm, and Ptotal ≤ 26 dBm, it has the ability to ensure that the overall radiation does not exceed the reference value, indicating that the network-side device can perform corresponding scheduling. When the scheduling by the network-side device exceeds the above capabilities, the terminal performs power back-off.
