Description

[0001] This application claims priority to Chinese Patent Application No. 202110681693.5, filed on June 19, 2021, entitled "A Method for Defining Power Levels", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of communications, and more specifically, to a method and apparatus for determining maximum output power. Background Technology

[0003] To improve network uplink coverage, high-power user equipment (HPUE), also known as high-power terminals, is becoming increasingly common, and terminals with multiple transmit radio frequency links are also becoming more prevalent.

[0004] Current technology introduces power class (PC) to calculate the maximum output power of a terminal. However, the power class corresponding to a combination of multiple transmit power levels in this technology cannot accurately reflect the true power level of the multiple transmit power levels; it is only an approximate value. For terminals with multiple transmit radio frequency links, since each transmit radio frequency link corresponds to a transmit power, meaning a terminal with multiple transmit radio frequency links has multiple transmit power levels, the base station can calculate the terminal's maximum output power based on the existing power class corresponding to the combination of multiple transmit power levels, and then perform transmit power scheduling based on the terminal's maximum output power. Therefore, in the above process, because the existing power class corresponding to the combination of multiple transmit power levels is an approximate value, it cannot accurately reflect the terminal's maximum output power, making transmit power scheduling based on the terminal's maximum output power unreasonable. Summary of the Invention

[0005] This application provides a method and apparatus for determining the maximum output power, in order to accurately determine the maximum output power of a terminal so as to reasonably schedule the transmission power based on the maximum output power.

[0006] In a first aspect, a method for determining maximum output power is provided. The method includes: determining indication information, the indication information being used to indicate the transmit power capability of a terminal, the transmit power capability being related to the maximum transmit power supported by multiple transmit radio frequency links of the terminal respectively, the transmit power capability being used to determine the maximum output power of the terminal; and sending the indication information to a network device.

[0007] Based on the above technical solution, the terminal indicates the transmission power capability related to the maximum transmission power supported by multiple transmission radio frequency links to the network device, so that the maximum output power calculated by the network device is more accurate, and thus the network device can perform more reasonable transmission power scheduling based on the terminal's maximum output power.

[0008] Secondly, a method for determining maximum output power is provided, the method comprising: receiving indication information from a terminal, the indication information indicating the terminal's transmit power capability, the transmit power capability being related to the maximum transmit power supported by multiple transmit radio frequency links of the terminal respectively, the transmit power capability being used to determine the terminal's maximum output power; and determining the maximum output power based on the indication information.

[0009] Based on the above technical solution, the terminal indicates the transmission power capability related to the maximum transmission power supported by multiple transmission radio frequency links to the network device, so that the maximum output power calculated by the network device is more accurate, and thus the network device can perform more reasonable transmission power scheduling based on the terminal's maximum output power.

[0010] In conjunction with the first or second aspect, in some possible implementations, the indication information is specifically used to indicate the maximum transmit power supported by each of the plurality of transmit radio frequency links.

[0011] By indicating the maximum transmit power supported by each of the multiple transmit radio links, network devices can determine the maximum output power of the terminal.

[0012] The following shows several possible forms of indication of the maximum transmit power supported by each of the multiple transmit RF links.

[0013] Optionally, the indication information includes the maximum transmit power value supported by each of the plurality of transmit links.

[0014] Optionally, the indication information includes the power levels corresponding to the maximum transmit power values ​​supported by the plurality of transmit links, with each maximum transmit power value corresponding to a power level.

[0015] Optionally, the indication information includes a first identifier and the number N of the plurality of transmit radio frequency links, wherein the first identifier belongs to a plurality of identifiers, and each of the plurality of identifiers and the number of transmit radio frequency links is used to jointly indicate one of a plurality of combinations, each of the plurality of combinations including a plurality of maximum transmit power values, the first identifier and the number N indicating a first combination, the plurality of combinations including the first combination, and the first combination including the maximum transmit power values ​​supported by the plurality of transmit radio frequency links respectively.

[0016] That is, the maximum transmit power supported by multiple transmit RF links is combined as a group and associated with an identifier. Since different terminals may have different numbers of transmit RF links, different mapping relationships can be defined for different numbers of transmit RF links. Therefore, one of the various combinations can be indicated by a combination of identifier and quantity. In other words, this mapping relationship includes the correspondence between the identifier and various combinations of transmit RF link quantities and various combinations of transmit power.

[0017] Optionally, the indication information includes a second identifier, which belongs to a plurality of identifiers. Each of the plurality of identifiers is used to jointly indicate one of a plurality of combinations. Each of the plurality of combinations includes a plurality of maximum transmit power values. The second identifier indicates a first combination. The plurality of combinations includes the first combination. The first combination includes the maximum transmit power values ​​supported by the plurality of transmit radio frequency links respectively.

[0018] It should be understood that this method differs from the first identifier mentioned above in that the mapping table corresponding to the second identifier can simultaneously reflect the mapping relationships of two, three, or more transmit radio frequency links, while the mapping table corresponding to the first identifier only reflects the mapping relationships of two, three, or more transmit radio frequency links.

[0019] Based on the several possible forms of indication of the maximum transmit power supported by each of the multiple transmit radio frequency links listed above, the network device can determine the maximum transmit power supported by each of the terminal's multiple transmit radio frequency links.

[0020] Furthermore, among the maximum transmit power values ​​supported by the multiple transmit RF links, the transmit RF link corresponding to the first maximum transmit power value is the main link, and the transmit RF links corresponding to the other maximum transmit power values ​​are auxiliary links.

[0021] In the presence of multiple terminals with the same maximum transmit power, different terminals can be distinguished by differentiating between primary and secondary links, which is more conducive to the rational scheduling of network devices.

[0022] In conjunction with the first or second aspect, in some possible implementations, the indication information is specifically used to indicate the power level of the terminal, and the power level is related to the maximum transmit power of the plurality of transmit radio frequency links in the following way:

[0023]

[0024] Where L represents the power level, P n P represents the maximum transmit power of the nth transmit radio frequency link out of N transmit radio frequency links. n>0, L>0, 1≤n≤N, N>1, n and N are integers.

[0025] By indicating the power level of the terminal instead of indicating the maximum transmit power supported by each of the terminal's multiple transmit RF links, the indication overhead can be reduced, and it also makes it easier for network devices to determine the terminal's maximum transmit power.

[0026] Optionally, the indication information includes a third identifier and the number N of the terminal's transmit radio frequency links. The third identifier belongs to multiple identifiers, and each of the multiple identifiers and the number of transmit power links are used to jointly indicate one of multiple power levels. The third identifier and the number N indicate the power level of the terminal, and the multiple power levels include the power level of the terminal.

[0027] That is, the power level of the terminal is associated with an identifier. Since different terminals may have different numbers of transmit radio frequency links, different mapping relationships can be defined for different numbers of transmit radio frequency links. Therefore, a power level can be indicated by a combination of identifier and quantity. In other words, this mapping relationship includes multiple combinations of identifier and transmit radio frequency link quantity and their correspondence with multiple power levels.

[0028] Optionally, the indication information includes a fourth identifier, which belongs to a plurality of identifiers, each of which is used to indicate one of a plurality of power levels, the fourth identifier indicating the power level of the terminal, and the plurality of power levels including the power level of the terminal.

[0029] It should be understood that this method differs from the third identifier mentioned above in that the mapping table corresponding to the fourth identifier can reflect the corresponding mapping relationships of two, three, or more transmit radio frequency links at the same time, while the mapping table corresponding to the third identifier only reflects the corresponding mapping relationships of two, three, or more transmit radio frequency links.

[0030] In conjunction with the first or second aspect, in some possible implementations, the indication information is also used to indicate the transmission mode applicable to one or more of the plurality of transmit radio frequency links.

[0031] By indicating the transmission mode, the network device knows the maximum transmit power of the transmit radio frequency link corresponding to different transmission modes of the terminal, thereby facilitating the network device to make reasonable scheduling of terminals in different transmission modes.

[0032] Furthermore, the indication information is also used to indicate the frequency band or band combination used in the transmission mode.

[0033] By indicating the frequency band or combination of frequency bands used in the transmission mode, the network device is informed of the frequency bands or combinations of frequency bands supported by the terminal in different transmission modes.

[0034] Thirdly, this application provides a maximum output power determination apparatus, including modules or units for implementing the methods of the first aspect, the second aspect, or any possible implementation of the first and second aspects. It should be understood that each module or unit can implement its corresponding function by executing a computer program.

[0035] Fourthly, this application provides a maximum output power determination apparatus, including a processor, the processor being configured to execute the maximum output power determination method described in the first aspect, the second aspect, or any possible implementation of the first and second aspects.

[0036] The device may further include a memory for storing instructions and data. The memory is coupled to the processor, which, when executing the instructions stored in the memory, can implement the methods described in the foregoing aspects. The device may also include a communication interface for communicating with other devices; exemplary, the communication interface may be a transceiver, circuit, bus, module, or other type of communication interface.

[0037] Fifthly, this application provides a chip system including at least one processor for supporting the implementation of the functions involved in the first aspect, the second aspect, or any possible implementation of the first and second aspects, such as receiving or processing data and / or information involved in the above methods.

[0038] In one possible design, the chip system also includes a memory for storing program instructions and data, which may be located within or outside the processor.

[0039] The chip system can consist of chips or include chips and other discrete components.

[0040] In a sixth aspect, this application provides a computer-readable storage medium including a computer program that, when run on a computer, causes the computer to implement the methods of the first aspect, the second aspect, or any possible implementation of the first and second aspects.

[0041] In a seventh aspect, this application provides a computer program product comprising: a computer program (also referred to as code or instructions) that, when the computer program is run, causes a computer to perform the methods of the first aspect, the second aspect, or any possible implementation of the first and second aspects.

[0042] It should be understood that the third to seventh aspects of this application correspond to the technical solutions of the first and second aspects of this application, and the beneficial effects achieved by each aspect and the corresponding feasible implementation are similar, and will not be repeated here.

[0049] To facilitate understanding, the terminology used in the embodiments of this application will be introduced first.

[0050] Terminal Power Level (PC): Terminals can report their own power level, indicating the terminal's default maximum output power. For ease of description, the terminal's power level will sometimes be represented by the parameter L in the following text.

[0051] It should be noted that in the embodiments of this application, different PCs are represented by different values ​​X, where X is a positive integer. It is important to note that PCX refers to the corresponding single power amplifier (PA) capability; that is, a power level represents only the power level corresponding to the maximum transmit power value supported by one transmit link, and cannot represent the power level corresponding to the combination of the maximum transmit power values ​​supported by multiple transmit links. This will be explained in detail below with specific examples.

[0052] Multiple transmit radio frequency links: In this embodiment, a terminal may have multiple transmit radio frequency links, each of which corresponds to a maximum transmit power. The power level L of the terminal can be calculated based on the maximum transmit power supported by each of the multiple transmit radio frequency links. Each transmit radio frequency link corresponds to a power amplifier (PA), and each transmit radio frequency link corresponds to a carrier power level.

[0053] The maximum output power of the terminal (P) CMAX,f,c ): Refers to the actual maximum output power of the terminal (P) CMAX,f,c The maximum output power P of the terminal. CMAX,f,c It can be determined based on Formula 1 and the power level L of the terminal:

[0054] P CMAX_L,f,c ≤P CMAX,f,c ≤P CMAX_H,f,c ……………………Formula 1

[0055] P CMAX_L,f,c =MIN{P EMAX,c -ΔT C,c ,(L-ΔL)-MAX(MAX(MPR c +ΔMPR c A-MPR c )+ΔT IB,c +ΔT C,c +ΔT RxSRS,c P-MPR c )}

[0056] P CMAX_L,f,c =MIN{P EMAX,c -ΔT C,c Since the definitions of parameters other than L are the same as those in the current technology in this embodiment, the specific meaning of each parameter will not be described here.

[0057] Carrier aggregation (CA): Aggregating two or more carrier units together to support greater transmission bandwidth.

[0058] Super uplink / supplementary uplink (SUL): A supplementary uplink used to improve uplink coverage for the terminal.

[0059] Dual-connectivity (DC): The terminal maintains connections with two network devices simultaneously.

[0060] It should be understood that CA, SUL, and DC mentioned above are several possible transmission modes under Uu transmission. Uu transmission specifically refers to universal (u) transmission between user network interfaces (U), that is, air interface transmission.

[0061] Vehicle-to-everything (V2X) is a key technology for future intelligent transportation systems. It enables communication between vehicles, between vehicles and base stations, and between base stations.

[0062] To facilitate understanding of the embodiments of this application, firstly, in conjunction with Figure 1 The communication system applicable to the embodiments of this application is described in detail. Figure 1 A schematic diagram of a communication system is shown, illustrating the method and apparatus for determining the maximum output power applicable to embodiments of this application. (See diagram below.) Figure 1 As shown, the communication system 100 may include at least one network device, such as Figure 1 The network device 110 shown; the communication system 100 may also include at least one terminal, for example Figure 1 The terminal 120 is shown. The network device 110 and the terminal 120 can communicate via a wireless link. In this embodiment, the terminal 120 can send indication information to the network device 110. After receiving the indication information, the network device 110 can calculate the maximum output power corresponding to the terminal based on the indication information and perform transmission power scheduling accordingly.

[0063] It should be understood that the network device in this wireless communication system can be any device with wireless transceiver capabilities. This equipment includes, but is not limited to: evolved node B (eNB), radio network controller (RNC), node B (NB), base station controller (BSC), base transceiver station (BTS), home base station (e.g., home-evolved node B, or home node B, HNB), baseband unit (BBU), access point (AP), wireless relay node, wireless backhaul node, transmission point (TP), or transmission and reception point (TRP) in a wireless fidelity (WIFI) system. It can also be a gNB in ​​a 5G system, such as a new radio (NR), or a transmission point (TRP or TP), one or a group of antenna panels (including multiple antenna panels) of a base station in a 5G system, or a network node constituting a gNB or transmission point, such as a baseband unit (BBU) or a distributed unit (DU).

[0064] In some deployments, a gNB may include a centralized unit (CU) and a distribution unit (DU). A gNB may also include a radio unit (RU). The CU implements some of the gNB's functions, and the DU implements others. For example, the CU implements radio resource control (RRC) and packet data convergence protocol (PDCP) layer functions, while the DU implements radio link control (RLC), media access control (MAC), and physical (PHY) layer functions. Since RRC layer information ultimately becomes PHY layer information, or is derived from PHY layer information, in this architecture, higher-layer signaling, such as RRC layer signaling, can be considered to be sent by the DU, or by the DU+CU. It is understood that network devices can be CU nodes, DU nodes, or devices including both CU and DU nodes. Furthermore, the CU can be classified as a network device in the radio access network (RAN) or as a network device in the core network (CN), and this application does not limit this.

[0065] It should also be understood that the terminal in this wireless communication system can also be referred to as user equipment (UE), access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication equipment, user agent, or user device. In the embodiments of this application, the terminal can be a mobile phone, tablet computer, computer with wireless transceiver capabilities, virtual reality (VR) terminal, augmented reality (AR) terminal, wireless terminal in industrial control, wireless terminal in self-driving, wireless terminal in remote medical care, wireless terminal in smart grid, wireless terminal in transportation safety, wireless terminal in smart city, wireless terminal in smart home, etc. The terminal can have multiple transmit radio frequency links.

[0066] To improve network uplink coverage, high-power terminals are becoming increasingly common, and correspondingly, terminals with multiple transmit radio frequency links are becoming more and more common.

[0067] Current technology introduces power classes to calculate the maximum output power of a terminal. However, the power class corresponding to a combination of multiple transmit powers in current technology cannot accurately reflect the true power levels of multiple transmit powers; it is only an approximate value. For ease of understanding, examples are provided in Tables 1 and 2. Table 1 shows various combinations of two maximum transmit powers for two transmit radio frequency links. In Table 1, the power class of NR carrier x and the power class of NR carrier y represent the maximum transmit power corresponding to each of the two transmit radio frequency links. Table 2 shows various combinations of two maximum transmit powers for three transmit radio frequency links. In Table 2, the power class of NR carrier x, the power class of NR carrier y, and the power class of NR carrier z represent the maximum transmit power corresponding to each of the three transmit links. In both Tables 1 and 2, UE power class represents the terminal's power class. The identifier can be an index, such as 1 to 4 in Table 1 and 1 to 8 in Table 2; or it can be other forms, such as cases a to d in Table 1 and cases a to h in Table 2. This application does not limit the specific form of the identifier.

[0068] Table 1

[0069] index / case UE power class NR Carrier x power class NR Carrier y power class 1 / case a 26dBm 23dBm 23dBm 2 / case b 26dBm 23dBm 26dBm 3 / case c 26dBm 26dBm 23dBm 4 / case d 26dBm 26dBm 26dBm

[0070] Here, decibel relative to one milliwatt (dBm) is an absolute value representing power. Any power P in milliwatts (mW) and dBm satisfies Formulas 2 and 3. Formula 2 can be used to convert power P in milliwatts (mW) to power value x in dBm, and similarly, Formula 3 can be used to convert power value x in dBm to the corresponding power P in milliwatts (mW).

[0071] x = 10log 10 (P / (1mW))……………………Formula 2

[0072] P = (1mW)10 (x / 10) ……………………Formula 3

[0073] As can be seen from Table 1, there are 2×2=4 combinations of the two maximum transmit power values ​​for the two transmit RF links, and all four combinations correspond to the same power level value. However, different combinations of the maximum transmit power corresponding to the two transmit RF links should have different power level values. This also reflects that the power level value of the terminal in Table 1 cannot accurately reflect the maximum output power of the terminal, thus making the calculation of the maximum output power of the terminal by the network device inaccurate.

[0074] Table 2

[0075]

[0076] Similar to Table 1, Table 2 shows that the two maximum transmit powers of the three transmit RF links can be combined in 2×2×2=8 ways. Among these 8 combinations, the combinations numbered 2-7 all correspond to the same power level value. However, different combinations of the maximum transmit power corresponding to the three transmit RF links should have different power level values. This also reflects that the power level value of the terminal in Table 2 cannot accurately reflect the maximum output power of the terminal, thus making the calculation of the maximum output power of the terminal by the network device inaccurate.

[0077] The technical solutions in this application will now be described with reference to the accompanying drawings.

[0078] Figure 2 This is a schematic flowchart illustrating a method 200 for determining the maximum output power from the perspective of interaction between the terminal and network devices. (For example...) Figure 2 As shown, Figure 2 The method 200 shown may include steps 210 to 230.

[0079] In step 210, the terminal determines the instruction information.

[0080] The indication information is used to indicate the terminal's transmit power capability, which is related to the maximum transmit power supported by the terminal's multiple transmit radio frequency links. The transmit power capability is used to determine the terminal's maximum output power.

[0081] For example, the indication information can indicate the terminal's transmit power capability in the following two ways.

[0082] The first possible implementation is that the indication information can be used to indicate the maximum transmit power supported by multiple transmit RF links of a terminal. There are three possible designs for this implementation, which will be described in detail below.

[0083] One possible design is that the indication information includes the maximum transmit power values ​​supported by multiple transmit links of a terminal. For example, if the maximum power values ​​of two transmit RF links of a terminal are 23dBm and 26dBm respectively, they can be reported to the network device in a combined form [23, 26]. As another example, if a terminal has three maximum power values ​​of 23dBm, 23dBm, and 26dBm respectively, they can also be reported to the network device in a combined form [23, 23, 26]. It should be understood that this explanation only considers the indication information content when a terminal has two or three transmit RF links. A terminal can also have more than three transmit RF links, and the indication information content is similar to the example above, so it will not be repeated here.

[0084] Another possible design is as follows: the indication information includes the power levels corresponding to the maximum transmit power values ​​supported by multiple transmit links of a terminal, with each maximum transmit power value corresponding to a power level. For example, if the maximum power values ​​of two transmit RF links of a terminal are 23dBm and 26dBm, and the power levels corresponding to these two maximum power values ​​are PC3 and PC2, then the power levels corresponding to the maximum transmit power values ​​supported by these two transmit links can be reported to the network device in a combined form [PC3, PC2]. As another example, if a terminal has three maximum power values ​​of 23dBm, 23dBm, and 26dBm, and the power levels corresponding to these three maximum power values ​​are PC3, PC3, and PC2, then the power levels corresponding to the maximum transmit power values ​​supported by these three transmit links can be reported to the network device in a combined form [PC3, PC3, PC2].

[0085] As mentioned earlier, PCX refers to the corresponding single PA capability. That is, a power level represents only the power level corresponding to the maximum transmit power value supported by one transmit link, and cannot represent the power level corresponding to the combination of the maximum transmit power values ​​supported by multiple transmit links. For example, PC2 only represents the power level corresponding to the maximum transmit power value of 26dBm supported by one transmit link, and cannot represent the power level corresponding to the combination of the maximum transmit power values ​​supported by two transmit links, 23+23dBm.

[0086] It should be understood that this explanation only uses the example of a terminal having two or three transmit radio frequency links. A terminal can also have more than three transmit radio frequency links, and the indication information is similar to the example above, so it will not be repeated here.

[0087] Another possible design is: the indication information includes a first identifier and the number N of multiple transmit radio frequency links of the terminal.

[0088] Wherein, the first identifier belongs to multiple identifiers, and each of the multiple identifiers and the number of transmit radio frequency links are used to jointly indicate one of the multiple combinations. Each of the multiple combinations includes multiple maximum transmit power values. The first identifier and the number N indicate the first combination. The multiple combinations include the first combination. The first combination includes the maximum transmit power values ​​supported by the multiple transmit radio frequency links of the terminal respectively.

[0089] In this design, the indication information is determined based on a mapping relationship. Specifically, this mapping relationship can include a correspondence between various combinations of identifiers and the number of transmit RF links, and various combinations of transmit power. Since different terminals may have different numbers of transmit RF links, different mapping relationships can be defined for different numbers of transmit RF links. Tables 3 and 4 show examples of mapping relationships corresponding to 2 transmit RF links and 3 transmit RF links.

[0090] Table 3

[0091]

[0092]

[0093] It can be understood that the NR Carrier x power class and NR Carrier y power class in Table 3 represent the maximum transmit power corresponding to the two transmit links, respectively. Table 3 shows four possible combinations of maximum transmit power of 23dBm or 26dBm supported by the two transmit RF links, each corresponding to a different identifier. These four different identifiers can be, for example, four different indices: 1, 2, 3, 4, or four different cases: case a, case b, case c, case d, or combinations of indices and cases, such as index 1 combined with case a, index 2 combined with case b, index 3 combined with case c, and index 4 combined with case d.

[0094] It should be noted that cases a, b, c, and d can not only correspond to the index, but also represent multiple implementation types, that is, multiple implementation types corresponding to the uplink transmit radio frequency link channels supported by the terminal. Therefore, indices 1, 2, 3, and 4 can correspond to cases a, b, c, and d respectively, and different indices can also be regarded as indicator codes corresponding to different implementation types. For ease of description, the first identifier, second identifier, third identifier, and fourth identifier in the embodiments of this application can all represent the index, case, or a combination of both in different mapping relationships. For brevity, the description of the same or similar cases is omitted in the following text.

[0095] It should be understood that Table 3 is merely an example and should not be construed as limiting the embodiments of this application. It should also be understood that the maximum transmit power of 23dBm and 26dBm supported by the two transmit radio frequency links shown in Table 3 are merely examples, and the maximum transmit power can also be other values, such as 29dBm, 31dBm, etc., which are not limited in the embodiments of this application.

[0096] Table 4

[0097] logo NR Carrier x power class NR Carrier y power class NR Carrier z power class 1 / case a 23dBm 23dBm 23dBm 2 / case b 26dBm 23dBm 23dBm 3 / case c 23dBm 26dBm 23dBm 4 / case d 23dBm 23dBm 26dBm 5 / case e 26dBm 26dBm 23dBm 6 / case f 23dBm 26dBm 26dBm 7 / case g 26dBm 23dBm 26dBm 8 / case h 26dBm 26dBm 26dBm

[0098] It can be understood that the NR Carrier x power class, NR Carrier y power class, and NR Carrier z power class in Table 4 represent the maximum transmit power corresponding to the three transmit links, respectively. Table 4 shows eight possible combinations of maximum transmit power of 23dBm or 26dBm supported by the three transmit RF links, each corresponding to one of eight different identifiers, such as eight different indices: 1, 2, 3, 4, 5, 6, 7, 8, or eight different cases: case a, case b, case c, case d, case e, case f, case g, case h. The specific meaning of each case can be found in the relevant description above, and will not be repeated here for brevity. It should be understood that Table 4 is merely an example and should not be construed as limiting the embodiments of this application. It should also be understood that the maximum transmit power of 23dBm and 26dBm supported by the two transmit RF links shown in Table 4 are merely examples, and the embodiments of this application do not limit the maximum transmit power supported by each transmit RF link.

[0099] Tables 3 and 4 include multiple mapping relationships, each of which contains a combination and its corresponding identifier. These mapping relationships can be predefined, such as protocol predefined relationships, or pre-stored in network devices and terminals, or pre-negotiated between the network devices and terminals; there are no limitations on this. Therefore, the terminal can determine indication information based on this mapping relationship. This indication information can include the number N of the terminal's multiple transmit radio frequency links, and the identifier (first identifier) ​​of the combination (i.e., the first combination) corresponding to the maximum transmit power value supported by each of the terminal's multiple transmit radio frequency links. Thus, the network device can obtain the maximum transmit power value supported by each of the terminal's multiple transmit radio frequency links based on the indication information (first identifier and number N of transmit radio frequency links) reported by the terminal, and thereby obtain the terminal's maximum output power.

[0100] For example, when the terminal includes 3 transmit RF links, and the maximum transmit power of the three transmit links is 23dBm, 23dBm, and 23dBm respectively, the first identifier is identifier 1 (or case a) based on the mapping relationship in Table 4. Furthermore, the terminal can determine that N in the indication information is 3, meaning the terminal includes 3 transmit RF links, and the first identifier in the indication information is identifier 1 (or case a). The corresponding indication information can be in the form of [3, 1] or [3, case a]. The network device can then find the maximum transmit power values ​​supported by the multiple transmit RF links corresponding to the terminal, which are 23dBm, 23dBm, and 23dBm respectively, based on the mapping relationship in Table 4 and the indication information. Then, substituting these three values ​​into Formula 4 below yields the terminal's power level L. Finally, based on the terminal's power level L and Formula 1 above, the terminal's maximum output power is obtained.

[0101] It should be understood that Tables 3 and 4 are merely examples. In another possible design, the maximum transmit power combinations with different numbers of transmit RF links can be combined into a single mapping relationship, where each combination of maximum transmit power supported by multiple transmit RF links corresponds to an identifier (second identifier). For example, Tables 3 and 4 can be merged into one table, and the identifier corresponding to each combination in the table can be redefined. Thus, a combination can be directly indicated by an identifier (second identifier). In this case, the indication information can include the second identifier.

[0102] Optionally, in the above-mentioned various possible designs, among the maximum transmit power values ​​supported by multiple transmit RF links, the transmit RF link corresponding to the first maximum transmit power value is the main link, and the transmit RF links corresponding to the other maximum transmit power values ​​are auxiliary links. For example, in combination [23, 26], 23 is the maximum transmit power value corresponding to the main link, and 26 is the maximum transmit power value corresponding to the auxiliary link. In combination [26, 23], 26 is the maximum transmit power value corresponding to the main link, and 23 is the maximum transmit power value corresponding to the auxiliary link. In combination [23, 23, 26], the first 23 is the maximum transmit power value corresponding to the main link, and the second 23 and 26 are the maximum transmit power values ​​corresponding to the auxiliary links. In combination [26, 23, 23], the first 26 is the maximum transmit power value corresponding to the main link, and 23 and 23 are the maximum transmit power values ​​corresponding to the auxiliary links. For example, the combinations corresponding to caseb and casec in Table 3 are [23, 26] and [26, 23], respectively. The maximum transmit power values ​​of the primary and secondary links corresponding to these two combinations are different. For the sake of simplicity, this will not be elaborated here.

[0103] Since different terminals support different maximum transmit power values ​​for their primary and secondary links, network devices allocate different uplink access resources to these different terminals, resulting in different gains for each terminal and different energy consumption for the corresponding network devices.

[0104] For example, for a terminal with two transmit radio links, the maximum transmit power value of the main link of one terminal is 26, and the maximum transmit power value of the auxiliary link is 23, corresponding to the combination [26, 23]. More specifically, in CA transmission mode, this case can be recorded as CA: case1 26NR1+23NR2; in E-UTRAN-NR dual connectivity (ENDC) transmission mode, this case can be recorded as ENDC: case1 26 LTE+23NR. The maximum transmit power value of the main link of the other terminal is 23, and the maximum transmit power value of the auxiliary link is 26, corresponding to the combination [23, 26]. More specifically, in CA transmission mode, this case can be recorded as CA: case2 23 NR1+26 NR2; in ENDC transmission mode, this case can be recorded as ENDC: case2 23 LTE+26 NR.

[0105] To facilitate understanding, the following analysis addresses cases 1 and 2 in CA and ENDC transmission modes respectively. In CA transmission mode, the uplink coverage (uplink signal range of the primary cell) differs between cases 1 and 2; case 1 has a greater uplink coverage than case 2, with the latter offering a 3dB coverage gain. This further impacts the network equipment's allocation of uplink access resources to each terminal. On one hand, case 1 terminals, especially those at the edge of the network, are more likely to preempt access resources due to the higher uplink signal limit of the primary cell. Therefore, the network equipment needs to allocate different uplink access resources to case 1 and case 2 terminals, such as physical random access channel (PRACH)-config 1 and PRACH-config 2, to prevent case 1 terminals from preempting access from case 2 terminals. Because the CA / DC access process involves first establishing the primary cell and then adding secondary cells, the primary cell carrier with higher power will have a greater gain during access. On the other hand, in ENDC transmission mode, the power consumption of case 1 terminals is higher than that of case 2. Due to the implementation of the NR waveform, NR consumes more power under the same high-power operating conditions. For example, when transmitting a total radiated power (TRP) of 26 dBm for LTE, the PA power is approximately 27-28 dBm, while for NR, the PA power is approximately 30-31 dBm.

[0106] It should also be understood that the above technical solution not only distinguishes between various scenarios of terminals with two transmit RF links, but also between various scenarios of terminals with three or more transmit RF links. For example, all eight combinations corresponding to three transmit RF links in CA transmission mode can be distinguished. The eight combinations are: case1 23 NR1+23 NR2+23 NR3, case2 23 NR1+26 NR2+23 NR3, case3 26 NR1+23 NR2+23 NR3, case4 23 NR1+23NR2+26 NR3, case5 26 NR1+26 NR2+23 NR3, case6 26 NR1+23 NR2+26 NR3, case7 23 NR1+26 NR2+26 NR3, and case8 26 NR1+26 NR2+26 NR3. For example, all eight combinations corresponding to the three transmit RF links in ENDC transmission mode can be distinguished. These eight combinations are: case 1 23 LTE + 23 NR1 + 23 NR2, case 2 23 LTE + 26 NR1 + 23 NR2, case 3 26 LTE + 23 NR1 + 23 NR2, case 4 23 LTE + 23 NR1 + 26 NR2, case 5 26 LTE + 26 NR1 + 23 NR2, case 6 26 LTE + 23 NR1 + 26 NR2, case 7 23 LTE + 26 NR1 + 26 NR2, and case 8 26 LTE + 26 NR1 + 26 NR2. For simplicity, they will not be listed individually here. Therefore, the above method can cover all transmit power matching conditions required by multi-transmit RF link terminals, thereby maximizing the flexibility of uplink high-power transmission.

[0107] Using the above method, network devices can determine the actual maximum uplink power of terminals and schedule them according to the power limit.

[0108] The second possible implementation is as follows: the indication information can specifically be used to indicate the power level of the terminal, and the relationship between the power level of the terminal and the maximum transmit power of multiple transmit RF links satisfies the following:

[0109]

[0110] Where L represents the power level of the terminal, P n P represents the maximum transmit power of the nth transmit radio frequency link out of N transmit radio frequency links. n >0, L>0, 1≤n≤N, N>1, n and N are integers.

[0111] In this case, the indication information includes a third identifier corresponding to the terminal's power level and the number N of the terminal's transmit radio frequency links. The third identifier is one of multiple identifiers, and each of these identifiers, along with the number of transmit power links, is used to jointly indicate one of multiple power levels. The third identifier and the number N indicate the terminal's power level, which is included among the multiple power levels.

[0112] For ease of understanding, the above scheme is explained below with reference to Tables 5 and 6. Tables 5 and 6 correspond to Tables 3 and 4 respectively, with the addition of corresponding terminal power levels, i.e., UE power classes in Tables 5 and 6, which is L in Formula 2 above. The UE power class in Table 5 is calculated from the maximum transmit power NRCarrier x power class and NR Carrier y power class corresponding to the two transmit links respectively. The UE power class in Table 6 is calculated from the maximum transmit power NR Carrier x power class, NR Carrier y power class, and NR Carrier z power class corresponding to the three transmit links respectively. The labels in Tables 5 and 6 are mainly used to identify the UE power class.

[0113] Optionally, the mapping relationships, such as those in Tables 5 and 6, can be predefined, such as protocol predefined relationships, or pre-stored in the network devices and terminals, or pre-negotiated between the network devices and terminals, without limitation. Therefore, the indication information determined by the terminal can include the third identifier and the number N of the terminal's transmit radio frequency links. In this way, the network device can obtain the terminal's power level based on the indication information (third identifier and the number N of transmit radio frequency links) reported by the terminal according to the mapping relationship, and thus directly obtain the terminal's maximum output power.

[0114] Table 5

[0115]

[0116]

[0117] It should be understood that Table 5 has a similar function to Table 1, but it can be seen that in Table 5, each of the four combinations of the two maximum transmit power of the two transmit RF links corresponds to a precise power level of the terminal.

[0118] Table 6

[0119]

[0120] It should be understood that Table 6 has a similar function to Table 2, but it can be seen that each of the eight combinations of the two maximum transmit power for the three transmit RF links shown in Table 6 corresponds to a precise terminal power level value.

[0121] For example, when N is 2 in the indication information, that is, the number of multiple transmit radio frequency links included in the terminal is 2, and the third identifier included in the indication information is identifier 1 (or case a), the corresponding indication information can be [2, 1] or [2, case a]. The network device can find the corresponding power level value of the terminal as 26.01dBm based on the mapping relationship in Table 5 according to the indication information. Then, based on the power level of the terminal as 26.01dBm and Formula 1 above, the maximum output power of the terminal can be obtained.

[0122] It should be understood that Tables 5 and 6 are merely examples. In another possible design, the maximum transmit power combinations with different numbers of transmit RF links can be merged into a mapping relationship, with each combination of maximum transmit power supported by multiple transmit RF links corresponding to an identifier (fourth identifier). For example, Tables 5 and 6 can be merged into one table, and the identifier corresponding to each combination in the table can be redefined. Thus, a combination can be directly indicated by an identifier (fourth identifier). In this case, the indication information can include the fourth identifier.

[0123] It should be understood that the specific meaning of "case" in the mapping relationship described above in conjunction with Tables 5 and 6 can be found in the relevant descriptions above, and will not be repeated here for the sake of brevity.

[0124] Optionally, for the above methods, the indication information may also be used to indicate the transmission mode applicable to one or more of the multiple transmit radio frequency links.

[0125] The transmission modes can be, for example, CA, SUL, DC, V2X, etc. Combining the above methods, the indication information could be, for example, [26, 23; CA, SUL, DC], indicating that the terminal can have two transmit radio links in CA, SUL, and DC transmission modes, with carrier power levels of 26dBm and 23dBm for the two transmit radio links, respectively. The indication information could also be [23, 26; CA, DC; 23, 23; SUL], indicating that the terminal can have two transmit radio links in all three transmission modes (CA, SUL, DC). In CA and DC transmission modes, the carrier power levels of the two transmit radio links are 26dBm and 23dBm, respectively, and in SUL transmission mode, the carrier power levels are 23dBm and 23dBm, respectively. Furthermore, the indication information could also be [CA, SUL, DC; 2, case a], indicating that the terminal can have two transmit radio links in all three transmission modes (CA, SUL, DC), with the corresponding combination identified as case a. For example, the indication information can also be [CA, SUL, DC; case a], which indicates that the terminal is identified by the combination of the three transmission modes CA, SUL, and DC as case a.

[0126] Alternatively, for the methods described above, the indication information can be used not only to indicate the transmission mode applicable to one or more of the multiple transmit radio frequency links, but also to indicate the frequency band or combination of frequency bands used in the transmission mode applicable to one or more of the multiple transmit radio frequency links.

[0127] One possible scenario is that some frequency bands and band combinations are active under one or more of the CA, SUL, and DC transmission modes applicable to Uu transmission. Another possible scenario is that all frequency bands and band combinations are active under one or more of the CA, SUL, and DC transmission modes applicable to Uu transmission. Combining the above methods, the indication information could be, for example, [26, 23; CA(band1), SUL(band2), DC(band3)], indicating that the terminal has two transmit radio frequency links corresponding to the CA, SUL, and DC transmission modes, with carrier power levels of 26dBm and 23dBm respectively, and the supported bands for each transmission mode. The indication information could also be, for example, [26, 23; CA(bandcombination), SUL(band combination), DC(band combination)], indicating that the terminal has two transmit radio frequency links corresponding to the CA, SUL, and DC transmission modes, with carrier power levels of 26dBm and 23dBm respectively, and the supported band combinations for each transmission mode. Here, "band combination" indicates that two or more frequency bands can be supported simultaneously in a certain transmission mode. For example, CA (band combination) can indicate that band A and band B are supported simultaneously in CA transmission mode. Indication information can also be [23, 26; CA (band combination), DC (band combination); 23, 23; SUL (band combination)], indicating that the terminal has two transmit radio links in CA, SUL, and DC transmission modes. In CA and DC transmission modes, the power levels of the carriers of the two transmit radio links are 26dBm and 23dBm, respectively, along with the supported band combinations in each mode. In SUL transmission mode, the power levels of the carriers of the two transmit radio links are 23dBm and 23dBm, along with the supported band combinations in that mode. Examples of V2X transmission modes will not be given here. Similar to the previous three transmission modes, the correspondence between the transmission mode and the maximum transmit power of each transmit radio link should be clearly defined and indicated in the corresponding position. Further details will not be elaborated here.

[0128] It should be understood that if the indication information does not indicate two transmit radio frequency links, the terminal is assumed to have a single transmit radio frequency link, and the network device will schedule the transmit power according to the terminal's default maximum output power; if the indication information indicates multiple transmit radio frequency links, the transmit power will be scheduled according to the maximum output power of the multiple transmit radio frequency links indicated in the above method.

[0129] In step 220, the terminal sends indication information to the network device. Accordingly, the network device receives the indication information from the terminal.

[0130] After the terminal determines the indication information according to step 210, it can send the indication information to the network device so that the network device can perform transmission power scheduling based on the maximum transmission power capability of the terminal in the indication information.

[0131] In step 230, the network device determines the maximum output power of the terminal.

[0132] The network device determines the terminal's maximum output power, corresponding to the method by which the terminal determines the indication information. There are two possible implementation methods. For the first implementation method in step 210: the network device can calculate the terminal's power level according to Formula 2, and then calculate the terminal's maximum output power based on the power level. For the second implementation method in step 210: since the corresponding terminal power level can be obtained from the indication information sent by the terminal, the terminal's maximum output power is obtained based on this power level. The formula for determining the terminal's maximum output power can be found in Formula 1, and will not be repeated here.

[0133] It should be understood that if the indication information specifies a transmission mode, the network device can determine the maximum output power of the terminal corresponding to that transmission mode and perform transmission power scheduling based on the indication information; if the indication information does not specify a transmission mode, the network device will perform transmission power scheduling according to the default maximum output power of the terminal.

[0134] Based on the above technical solution, the terminal indicates the transmission power capability related to the maximum transmission power supported by multiple transmission radio frequency links to the network device, so that the maximum output power calculated by the network device is more accurate, and thus the network device can perform more reasonable transmission power scheduling based on the terminal's maximum output power.
