Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a power adjustment method and apparatus. Background Technology

[0002] User equipment (UE) may experience transmit power changes between two uplink transmissions. When a UE experiences a transmit power change between two uplink transmissions, a transition time is required to complete the power adjustment. Currently, the transition time for transmit power adjustment is constrained by protocol specifications. For 4G mobile communication technology, the UE transmit power adjustment transition time is 40μs, and for 5G mobile communication technology, the UE transmit power adjustment transition time is 10μs.

[0003] Because the transition time for transmit power adjustment is often accompanied by amplitude and phase changes due to power jumps, it affects the error vector magnitude (EVM) of the transmitted signal. Therefore, using EVM to measure whether the UE has completed the transmit power adjustment within the transition time has become a trend. With the development of radio frequency (RF) devices and power management technologies, the continuous compression of transmit power adjustment transition times ensures rapid power switching during signal transmission, thereby guaranteeing uplink signal transmission performance. Therefore, UE capability reporting regarding transition time has become a hot topic in 5G mobile communication; that is, the UE can report transition time values ​​shorter than 10μs through capability values. How to accurately measure this transition time value has also become a focal point. Summary of the Invention

[0004] This application provides a power adjustment method and apparatus for accurately measuring the transition time value.

[0005] Firstly, this application provides a power adjustment method, which includes: a terminal device reporting capability information of the transition time for two uplink transmission transmit power adjustments to a network device, the capability information including a first transition time value, the first transition time value being the transition time value when the terminal device performs power adjustment. During the transmit power adjustment process of an RF device, the amplitude and phase of the transmitted signal may become unstable due to changes in power supply, causing variations in the amplitude or phase of the device's own transmitted signal. During the transition time, the signal's EVM deteriorates, leading to a decrease in the base station's demodulation performance. The transition time describes the time required for power change. Since EVM is an important indicator of transmit signal quality and the basis for the base station's demodulation performance after receiving the uplink signal, the stability of EVM becomes an indicator of whether power switching is complete.

[0006] With the development of radio frequency devices and power management technologies, the continuous compression of the transition time for transmit power adjustment ensures rapid power switching during signal transmission, thereby guaranteeing uplink signal transmission performance. Therefore, UE capability reporting regarding transition time has become a hot topic in 5G mobile communication; that is, the UE can report a transition time value shorter than 10μs using a capability value. Currently, this capability value for the UE is considered to be one of 1μs, 2μs, 4μs, 7μs, and 10μs. The first transition time value is one or more of at least one transition time, and the at least one transition time corresponds to the subcarrier spacing (SCS) supported by the terminal device; the terminal device performs power adjustment based on the first transition time value.

[0007] In the above technical solution, the terminal device can report capability information containing transition time values ​​to the network device according to the correspondence between the SCS it supports and the transition time. This ensures that the transition time values ​​reported by the terminal device can be measured.

[0008] In this application, the power variation range of the terminal device includes at least one, and there is a correspondence between the power variation range and the transition time value. In one possible implementation, each power variation range of the terminal device may correspond to a first transition time value.

[0009] In one possible implementation, the terminal device performs power adjustment based on the transition time value, including:

[0010] The terminal device determines a second transition time value corresponding to the second power change range based on the second power change range and the correspondence between the power change range and the first transition time value. The terminal device then evenly distributes the second transition time value at the boundary between the two symbols or time slots where power adjustment is performed. In other words, when performing power adjustment, the terminal device can determine the transition time required for the current power change based on the actual power change range between the two current uplink transmissions and the transition time values ​​corresponding to different power change ranges, and then perform power adjustment based on the required transition time.

[0011] In the above technical solution, the terminal device can determine the transition time value corresponding to the actual power change range based on the correspondence between the power change range and the transition time value, and then adjust the power according to the determined transition time value.

[0012] In this application, different power variation ranges can correspond to different transition time values. For example, when the power variation range is <= A, the transition time value is T1; when A < power variation range <= B, the transition time value is T2; when B < power variation range <= C, the transition time value is T3.

[0013] In one possible implementation, the second power variation range may include the following:

[0014] The first type: The second power change range is the power change range between two actual uplink transmissions. In this embodiment, the power change range to which the power change range between two actual uplink transmissions belongs can be determined based on the correspondence between the power change range and the transition time value. That is, the subset corresponding to the second power change range is determined, i.e., it is determined which of the three ranges the second power change range belongs to: power change range <= A, A < power change range <= B, and B < power change range <= C.

[0015] The second type: The second power change range is the maximum power change range among the at least one power change range. In this embodiment, regardless of the actual power change range of the two uplink transmissions, the second power change range is considered to belong to the range B < power change range <= C. That is, the terminal device adjusts the power according to the transition time value T3.

[0016] The third type: The second power change range is a reference value within the power change range. The reference value of the power change range is a reference value agreed upon in the protocol or a reference value configured by the network device for the terminal device. If the reference power change range is A, then regardless of the actual power change range of the two uplink transmissions, the terminal device adjusts the power according to the transition time value T1.

[0017] In one possible implementation, the set of reportable transition time values ​​can be determined based on the subcarrier spacing (SCS) supported by the terminal device. There may be a correspondence between the set of reportable transition time values ​​and the SCS supported by the terminal device; when the SCS supported by the terminal device are different, the set of reportable transition time values ​​may be different.

[0018] For example, if the subcarrier spacing (SCS) supported by the terminal device is 15 kHz, the transition time values ​​are 7 μs and 10 μs; if the subcarrier spacing (SCS) supported by the terminal device is 30 kHz, the transition time values ​​are 4 μs and 10 μs; if the subcarrier spacing (SCS) supported by the terminal device is 60 kHz, the transition time values ​​are 2 μs and 10 μs.

[0019] Of course, the terminal device can also support multiple different SCSs simultaneously. As an example, the terminal device can support two different SCSs simultaneously. For instance, if the terminal device supports subcarrier spacing SCSs of 15kHz and 30kHz, the transition time values ​​are 7μs, 4μs, and 10μs; if the terminal device supports subcarrier spacing SCSs of 15kHz and 60kHz, the transition time values ​​are 7μs, 2μs, and 10μs; if the terminal device supports subcarrier spacing SCSs of 30kHz and 60kHz, the transition time values ​​are 4μs, 2μs, and 10μs. If the terminal device supports subcarrier spacing SCSs of 15kHz and 30kHz, the transition time values ​​are 7μs, 4μs, and 10μs.

[0020] As another example, the terminal device can simultaneously support three different SCSs. For instance, if the terminal device supports subcarrier spacing SCSs of 15kHz, 30kHz, and 60kHz, then the transition time values ​​are 7μs, 4μs, 2μs, and 10μs, respectively.

[0021] Secondly, this application provides a power adjustment method, the method comprising: a terminal device reporting capability information to a network device, the capability information including a first transition time value, the first transition time value being a transition time value when the terminal device performs power adjustment; the first transition time value being one of at least one transition time, and the at least one transition time corresponding to a subcarrier spacing (SCS) supported by the terminal device; the terminal device performing power adjustment according to the first transition time value.

[0022] In this embodiment, the terminal device can report only one transition time to the network device, and then the terminal device can adjust its power based on this reported transition time value. Through this method, the terminal device can report the transition time required for power adjustment using a capability value, and can adjust its power based on a single reported transition time value.

[0023] In one possible implementation, each of at least one power variation range of the terminal device corresponds to a first transition time value; wherein the first transition time value corresponds to a first power variation range. That is, a unique transition time value reported by the terminal device corresponds to a unique power variation range.

[0024] In the above technical solution, the terminal device can calculate the transition time value corresponding to other power change ranges based on the correspondence between the reported unique transition time value and the power change range, thereby enabling the terminal device to adjust the power based on the calculated transition time value.

[0025] In one possible implementation, the first power variation range is a preset power variation range; or the maximum power variation range among the at least one power variation range; or a reference value among the power variation ranges, wherein the reference value of the power variation range is a pre-agreed reference value or a reference value configured by the network device for the terminal device. In this technical solution, the power variation range corresponding to the unique transition time value reported by the terminal device can be any one of the above three cases. In this way, the terminal device can calculate the transition time value corresponding to other power variation ranges based on one of the above three power variation ranges, and then adjust the power according to the calculated transition time value.

[0026] In one possible implementation, the terminal device performs power adjustment based on the transition time value, including:

[0027] The terminal device determines a second transition time value corresponding to the second power change range based on the second power change range and the correspondence between the power change range and the first transition time value; the terminal device evenly distributes the second transition time value at the boundary of the two symbols or time slots where power adjustment is performed.

[0028] It should be noted that the second power variation range can be understood as the power variation range between the two actual uplink transmissions. In this application, the terminal device can calculate the transition time corresponding to other power variation ranges based on a reported transition time value and the power variation range corresponding to that unique transition time value. Specific calculation methods can be found in the detailed embodiments section of the specification, and will not be elaborated upon here.

[0029] In one possible implementation, the at least one transition time has the following correspondence with the subcarrier spacing (SCS) supported by the terminal device:

[0030] When the subcarrier spacing (SCS) supported by the terminal device is 15 kHz, the transition time values ​​are 7 μs and 10 μs; when the subcarrier spacing (SCS) supported by the terminal device is 30 kHz, the transition time values ​​are 4 μs and 10 μs; when the subcarrier spacing (SCS) supported by the terminal device is 60 kHz, the transition time values ​​are 2 μs and 10 μs; and when the subcarrier spacing (SCS) supported by the terminal device is 15 kHz and 30 kHz, the transition time values ​​are 7 μs and 4 μs. The transition time values ​​are 7μs, 2μs, and 10μs when the subcarrier spacing (SCS) supported by the terminal device is 15kHz and 60kHz; the transition time values ​​are 4μs, 2μs, and 10μs when the subcarrier spacing (SCS) supported by the terminal device is 30kHz and 60kHz; and the transition time values ​​are 7μs, 4μs, 2μs, and 10μs when the subcarrier spacing (SCS) supported by the terminal device is 15kHz, 30kHz, and 60kHz.

[0031] In the above technical solutions, the transition time value may differ depending on the SCS supported by the terminal device. The terminal device can report different transition time values ​​based on the different SCS it supports.

[0032] Thirdly, this application also provides a capability reporting method, which includes: a terminal device determining one or more first transition time values ​​from at least one transition time based on a power change range; the power change range includes at least one, and the power change range corresponds to the first transition time value; the terminal device reporting capability information to a network device, the capability information including the first transition time value.

[0033] In the above technical solution, when reporting capability information, the terminal device can determine the transition time value based on the power change range, and then report the transition time value as the UE capability value to the network device. Through this method, the terminal device can report the transition time required for power adjustment using the capability value, and this capability reporting method is independent of the SCS supported by the terminal device, while enabling accurate power adjustment based on the reported transition time.

[0034] In one possible implementation, at least one transition time is pre-configured / agreed. In the embodiments of this application, the transition time can be pre-configured by the terminal device or pre-agreed by the network. Then, the terminal device can determine the transition time value to be reported within the transition time according to the power change range, and then adjust the power according to the reported transition time value.

[0035] In one possible implementation, the terminal device performs power adjustment based on the first transition time value, including: the terminal device determining a second transition time value corresponding to the second power change range based on the second power change range and the correspondence between the power change range and the first transition time value; and the terminal device evenly distributing the second transition time value at the boundary of the two symbols or time slots where power adjustment is performed.

[0036] In the above technical solution, when the terminal device performs power adjustment, it can determine the transition time required for power adjustment based on the correspondence between the power change range and the transition time value, and then distribute the determined transition time evenly at the boundary of the two symbols or time slots, thereby completing the power adjustment.

[0067] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the embodiments of this application will be further described in detail below with reference to the accompanying drawings.

[0068] The embodiments of this application can be applied to various mobile communication systems, such as: new radio (NR) systems, long term evolution (LTE) systems, advanced long term evolution (LTE-A) systems, universal mobile telecommunication system (UMTS), evolved long term evolution (eLTE) systems, evolved UMTS terrestrial radio access-NR dual connectivity (ENDC) systems, future communication systems, and other communication systems. Specifically, no limitation is made here.

[0069] like Figure 1 The illustration shows an application scenario according to an embodiment of this application. In this scenario, a network device can serve one or more terminal devices. Figure 1 This is just one example from a terminal device. It should be understood that... Figure 1 This is a simplified illustration for ease of understanding only. This application scenario may also include other network devices or other terminal devices. Figure 1 It was not drawn in the middle.

[0070] 1) Network devices, such as access network (AN) devices, can be, for example, base stations (e.g., access points), which can refer to devices in the access network that communicate with wireless terminal devices over the air interface via one or more cells, or, for example, roadside units (RSUs) in a vehicle-to-everything (V2X) technology. Base stations can be used to convert received air frames to and from IP packets, acting as routers between terminal devices and the rest of the access network, which may include an IP network. RSUs can be fixed infrastructure entities supporting V2X applications and can exchange messages with other entities supporting V2X applications. Network devices can also coordinate the management of air interface attributes. For example, network equipment may include evolved base stations (NodeB, eNB, or e-NodeB) in long term evolution (LTE) systems or long term evolution-advanced (LTE-A) systems, or it may include next-generation node B (gNB) in the 5th generation (5G) new radio (NR) system (also referred to as NR system), or it may include centralized units (CU) and distributed units (DU) in cloud radio access network (Cloud RAN) systems. The embodiments of this application are not limited, and of course, network equipment may also include core network equipment.

[0071] 2) Terminal equipment refers to a device with wireless transceiver capabilities or a chip that can be installed in such a device. The device with wireless transceiver capabilities can also be referred to as user equipment (UE), access terminal, user unit, user station, mobile station, remote station, remote terminal, mobile device, user terminal, user agent, or user device.

Figure 1 The network equipment in this context can also correspond to the network equipment in future mobile communication systems. Figure 1 Taking a base station as an example of network equipment, as mentioned above, network equipment can also be core network equipment.

[0073] The following explanations of some terms used in the embodiments of this application are provided to facilitate understanding by those skilled in the art.

[0074] 1) Definition of power control:

[0075] Taking physical uplink shared channel (PUSCH) as an example, the transmit power is defined in protocol TS38.213 as follows:

[0076]

[0077] Among them, PCMAX Indicates the UE's maximum configured transmit power. This indicates the target PSD configuration at the cell and UE levels. For serving cell c, carrier f, transmission opportunity i within the uplink active bandwidth b is the resource size allocated to PUSCH, PL b,f,c (q d ) is the UE side indexed by the reference signal q d Calculated downlink path loss, f b,f,c This refers to the power adjustment value for closed-loop power control issued via transmit power control (TPC) commands.

[0078] Between two uplink scheduling events, the number of resource blocks (RBs), path loss (PL), or P may vary. CMAX Different factors cause variations in uplink transmit power.

[0079] During a change in transmit power, a transition period may be required to complete the power change. The transition period is defined in protocol TS38.101; see [link / reference]. Figure 2A , Figure 2B as well as Figure 2C The transient period is described below. Power changes can occur between any two physical channels or signals, such as between PUSCH and PUSCH switching, between PUCCH and PUCCH switching, or between PUSCH and PUCCH switching, etc.

[0080] 2) Transient period:

[0081] Transition time refers to the time required for the transmit power of a terminal device to change from on-power 1 to on-power 2, or the time required for the transmit power of a terminal device to change between off-power and on-power. The measurement benchmark for transition time can be the EVM index; that is, from a measurement perspective, transition time can refer to the time required for the EVM to stabilize during the process of the terminal device's transmit power changing from on-power 1 to on-power 2 (or from off-power to on-power). Off-power refers to the power value that the EVM must reach or fall below when the transmitter is turned off, and on-power refers to a certain transmit power value when the EVM transmitter is turned on.

[0082] It should be noted that the Transient period can be recorded as the transition time, or it can also be recorded as other names. For example, it can also be called the adjustment time, the change time, the adjustment period, etc. This application does not make any limitations on this.

[0083] As Figure 2A shown, assuming that time slot N +2 is to be switched to SRS, the power change can be completed entirely outside the SRS symbol. Similarly, when SRS is switched to time slot N +1 the power change is also completed outside the SRS symbol. When time slot N +1 is to be switched to time slot N0, the Transient period required for the power change can be evenly distributed over two time slots or symbols.

[0084] As Figure 2B shown, when switching between a long time slot and a short time slot, the transition time is allocated on the side of the long time slot. That is to say, the transition time required for the power change is completed on the side of the long time slot. For example, when switching from long time slot N+2 to short time slot N+1, the time from the start of power change (Start of power) to the end of power change (End of power) experiences a Transient period of 10 μs, and the 10 μs is allocated on the side of long time slot N+2. Another example is when switching from short time slot N+1 to long time slot N, the Transient period required for the power change from start to end is 10 μs, and the 10 μs is allocated on the side of long time slot N.

[0085] It should be noted that the number of symbols M1 in the long subslot satisfies the relationship: 2 < M1 <= 14, and the number of symbols M2 in the short subslot satisfies the relationship: M2 <= 2. Here, both M1 and M2 are positive integers.

[0086] As Figure 2C shown, when switching from a short time slot to a short time slot, the Transient period can be evenly distributed at the boundary of the two short time slots. For example, when switching from short time slot N+1 to short time slot N, the power change starts from short time slot N+1 and ends at short time slot N, and the required Transient period is 10 μs. That is to say, the change is 5 μs on each of the two short time slots.

[0087] Based on the above introduction of the Transient period, to determine whether the power change can be completed within the transition time Transient period, the Error Vector Magnitude (EVM) can be used for measurement and verification. The following introduces the EVM.

[0088] The TS38.101 protocol defines the EVM window and the EVM measurement process. EVM measurement requires a basic signal demodulation process, which includes a Fast Fourier Transform (FFT) process. The selection of the FFT window needs to be combined with the length of the cyclic prefix (CP).

[0089] For example, see Tables 1 and 2, which show the relationship between the length of the EVM window and the CP length under different subcarrier intervals.

[0090] Table 1 shows the relationship between the EVM window and the CP length when the subcarrier spacing is 15 kHz.

[0091]

[0092] Table 2 shows the relationship between the EVM window and the CP length when the subcarrier spacing is 30kHz.

[0093]

[0094] According to Tables 1 and 2, the length of the EVM window is half the length of the CP window.

[0095] See below Figure 3 As shown, the EVM window is introduced. Figure 3 As shown, Figure 3 The shaded area represents the EVM window, whose length is half the length of the CP. In other words, the size of the EVM window changes with the size of the CP; the longer the CP, the longer the EVM window, and vice versa.

[0096] During the measurement, the FFT window was cropped twice at each symbol, and the EVM measurements were recorded as EVM. L and EVM H And the final EVM measurement result is the maximum of the two. When EVM L EVM H At that time, EVM = EVM L When EVM H EVM L At that time, EVM = EVM H .

[0097] As we know from the previous introduction, since the current transient period is 10μs, which is much longer than the CP length and the EVM window length, it is impossible to test the 10μs transient period.

[0098] Table 3 shows the relationship between the EVM exclusion window and the CP length under different SCS. See Table 3 for details.

[0099] Table 3. Relationship between EVM window and CP length under different SCS.

[0100]

[0101] Combination Figure 3 For EVM in Table 3 L EVM H Let me explain. Taking 15kHz as an example, Figure 3 The dashed lines can include 1, 2, 3, and 4. The distance between dashed line 1 and dashed line 2 is 1.175 μs, and the distance between dashed line 1 and dashed line 3 is 3.525 μs.

[0102] UE capability reporting for transition time has become a hot topic in 5G mobile communication. UE capability values ​​can include: 1μs, 2μs, 4μs, 7μs, and 10μs. When the UE capability value for transition time equals 150% of the CP length, the truncation of the EVM window can be used to determine whether the UE meets the EVM index after a power change. For example, if the transition period is 7μs, and it is evenly distributed at the boundary of the power change, then half of the even distribution is 3.5μs. According to Table 3, if the EVM is taken... H This allows for a measurement of 7μs. In other words, at an SCS of 15kHz, the UE capability value of 7μs can be measured using EVM. Specifically, EVM = min(EVM) L EVM H This serves as the benchmark for EVM measurements. Using the same benchmark, it can be concluded that a UE capability value of 4μs can be measured at 30kHz, and a UE capability value of 2μs can be measured at 60kHz.

[0103] Assuming UE capability values ​​are 1μs, 2μs, 4μs, 7μs, and 10μs, the measurable UE capability values ​​differ under different SCSs. The specific correspondences are shown in Table 4. It can be understood that the UE capability value is the measurable transition time.

[0104] Table 4. Correspondence between UE-supported SCS and measurable transition time

[0105] SCS supported by UE on NR Measurable transition period 15kHz 7μs 15kHz + 30kHz 4μs, 7μs 15kHz + 60kHz 2μs, 7μs 15kHz+30kHz+60kHz 2μs, 4μs, 7μs 30kHz 4μs 30kHz + 60kHz 2μs, 4μs 60kHz 2μs

[0106] The following section describes the EVM measurement process, taking a UE-supported SCS of 15kHz and a measurable transition time of 7μs as an example.

[0107] like Figure 4A The diagram shown is a schematic representation of EVM measurement of a previous symbol according to an embodiment of this application. Figure 4A In the context of EVM, when the SCS is 15kHz, H For 3.525 μs, EVM L The first transition time is 1.175 μs. Half of the first transition time is 3.5 μs, taken as EVM. L The timing is just right to remove the 3.5μs data samples at the end of the sign, while EVM H Only the 1.175 μs at the end of the symbol is removed, so the final min(EVM) on the previous symbol is... L EVM H The value of ) is EVM L .

[0108] like Figure 4B The diagram shown is a schematic representation of EVM measurement of the latter symbol according to an embodiment of this application. Figure 4B In the first transition time, half of the value is 3.5 μs, and the EVM is taken as... H This is just enough to remove the 3.5μs in CP, EVM L Removing only the 1.175μs of CP, EVM L The value will be affected by the portion of the signal whose EVM has not yet been recovered from the FFT window, therefore the final min(EVM) value will be less than the value of the EVM on the next symbol. L EVM H The value of ) is EVM H .

[0109] It should be noted that when power changes occur, the EVM measurement is ultimately taken as the EVM value. L and EVM H The minimum value in.

[0110] As can be seen from the foregoing introduction, the reporting of UE capabilities for transition time has become an unresolved issue. This application provides a power adjustment method in which the measurable transition time of the UE, i.e., the UE capability value, can be reported according to the correspondence in Table 4 above. Furthermore, the reporting is based on the correspondence between the UE capability value and the SCS, thereby ensuring that the capability values ​​reported by the UE are all measurable and that there will be no situation where the reported capability values ​​cannot be measured.

[0111] The terms "system" and "network" in the following embodiments of this application are used interchangeably. "At least one" means one or more, and "more than one" means two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, or c can represent: a, b, c, ab, ac, bc, or abc, where a, b, and c can be single or multiple.

[0112] Furthermore, the ordinal numbers such as "first" and "second" mentioned in the embodiments of this application are used to distinguish multiple objects, and are not used to limit the order, sequence, priority or importance of multiple objects.

[0113] like Figure 5 The diagram shown is a flowchart of a power adjustment method provided in an embodiment of this application. (See attached diagram.) Figure 5 As shown, the method may include the following steps:

[0114] S501: The terminal device reports capability information to the network device, the capability information including a first transition time value, the first transition time value being one or more of at least one transition time.

[0115] Wherein, the first transition time value is the transition time value when the terminal device performs power adjustment. The first transition time value is one or more of at least one transition time, and the at least one transition time corresponds to the subcarrier spacing (SCS) supported by the terminal device. It should be noted that the transition time may include: 1μs, 2μs, 4μs, 7μs, 10μs.

[0116] In this embodiment of the application, the UE can report different transient periods depending on the SCS it supports. For example, the correspondence between the SCS supported by the UE and the transient periods that can be reported can be seen in Table 5.

[0117] Table 5. Correspondence between UE-supported SCS and reportable transition time

[0118] SCS supported by UE on NR Reportable transition period 15kHz 7μs, 10μs 15kHz + 30kHz 4μs, 7μs, 10μs 15kHz + 60kHz 2μs, 7μs, 10μs 15kHz+30kHz+60kHz 2μs, 4μs, 7μs, 10μs 30kHz 4μs, 10μs 30kHz + 60kHz 2μs, 4μs, 10μs 60kHz 2μs, 10μs

[0119] As shown in Table 5, the capability information that the terminal device can report to the network device can be determined based on the SCS supported by the terminal device. For example, when the terminal device supports an SCS of 15kHz, the first transition time value that can be reported is 7μs; when the terminal device supports an SCS of 30kHz and 60kHz, the first transition time values ​​that can be reported are 2μs and 4μs, respectively.

[0120] In this application embodiment, the correspondence between at least one transition time and the subcarrier spacing (SCS) supported by the terminal device may include the following cases:

[0121] (1) When the subcarrier spacing (SCS) supported by the terminal device is 15KHz, the transition time value is 7μs and 10μs.

[0122] (2) When the subcarrier spacing (SCS) supported by the terminal device is 30KHz, the transition time value is 4μs and 10μs.

[0123] (3) When the subcarrier spacing (SCS) supported by the terminal device is 60KHz, the transition time value is 2μs and 10μs.

[0124] (4) When the subcarrier spacing (SCS) supported by the terminal device is 15KHz and 30KHz, the transition time value is 7μs, 4μs and 10μs.

[0125] (5) When the subcarrier spacing (SCS) supported by the terminal device is 15KHz and 60KHz, the transition time value is 7μs, 2μs and 10μs.

[0126] (6) When the subcarrier spacing (SCS) supported by the terminal device is 30KHz and 60KHz, the transition time value is 4μs, 2μs and 10μs.

[0127] (7) When the subcarrier spacing (SCS) supported by the terminal device is 15KHz, 30KHz and 60KHz, the transition time value is 7μs, 4μs, 2μs and 10μs.

[0128] That is, the UE reports the Transient period capability value based on the SCS it can support.

[0129] Furthermore, the method of reporting capability information may differ for different UEs. In some embodiments, for stand-alone (SA) UEs, the UE must support SCS of 15kHz and 30kHz, meaning the UE can report a transient period of at least 4μs, 7μs, or 10μs. For SA UEs, 60kHz is an optional supported SCS. When the UE supports 60kHz, a 2μs report is allowed; when the UE does not support 60kHz, a 2μs report is not permitted.

[0130] In other embodiments, for non-standalone (NSA) UEs, the supported SCSs are reported in combination. For example, for UEs supporting ENDC, the SCSs supported on NR can be reported according to capabilities, and only the transition time values ​​corresponding to the supported SCSs are allowed to be reported.

[0131] S502: The terminal device adjusts the power according to the first transition time value.

[0132] In this embodiment of the application, when the terminal device performs power adjustment, it can determine the transition time required for the current power change based on the actual power change range between two uplink transmissions and the terminal device's own transition time capability corresponding to different power change ranges, and then perform power adjustment based on the transition time required for the current power change.

[0133] In one possible implementation, the power variation range during power adjustment by the terminal device corresponds to the transition time UE capability. Specifically, the power variation range includes one or more, and each power variation range of the terminal device has a corresponding transition time capability. For example, if the power variation range includes {20dB, 30dB}, and the terminal device reports a transition time capability value of {4μs, 7μs} corresponding to each power variation range, then when the power variation range is 20dB, the transition time capability is 4μs, and when the power variation range is 30dB, the transition time capability is 7μs. It is understood that the above example is merely illustrative, and this application is not limited thereto.

[0134] It should be noted that in this application, the transition time capability value is the same as the transition time. Since the transition time is a UE capability, the transition time capability value can also be understood as the UE capability value.

[0135] Optionally, the terminal device may also report the correspondence between the power change range and the first transition time value to the network device. That is, when reporting capability information, the terminal device may report the first transition time value to the network device, or it may report the correspondence between the first transition time value and the power change range to the network device.

[0136] In this application, the UE can pre-configure the correspondence between the first transition time value and the power change range, and store the correspondence. As an example, the correspondence between the first transition time value and the power change range (e.g., ΔP) can be found in Table 6.

[0137] Table 6. Correspondence between the first transition time value and the power change range

[0138] Power variation range First transition time value ΔP<=20dB 4μs 20dB<ΔP<=30dB 7μs 30dB<ΔP<=50dB 10μs

[0139] Of course, it is understood that the above table is only an illustrative example, and the correspondence in this application is not limited to the examples in the table. For example, it could also be that when the power change range is 20dB, the corresponding transition time value is 2μs; when the power change range is 30dB, the corresponding transition time value is 4μs, etc.

[0140] Furthermore, the correspondence between the transition time capability value and the power variation range is not limited to the form of the table above, and this application does not limit it in this regard. For example, it can also be described in words.

[0141] As one possible implementation, when the terminal device adjusts its power based on the transition time value, the UE can determine the subset corresponding to the actual power change range of the two uplink transmissions based on the correspondence between the reported power change range and the transition time capability. For example, the correspondence between the power change range reported by the UE and the transition time capability is shown in Table 6. When the actual power change range is 25dB, it corresponds to the power change range of 20dB < ΔP <= 30dB in Table 6, and the corresponding transition time value is 7µs. At this time, the UE can adjust its power based on the corresponding transition time value. The transition time value is placed at the boundary of the two time slots or symbols in the order of (3.5 + 3.5)µs, that is, the UE can make power changes 3.5µs in advance at the time domain boundary of the time slot or symbol.

[0142] As another possible implementation, when the terminal device adjusts its power, it can do so only based on the transition time value corresponding to the maximum power change range in the correspondence between power change range and transition time capability. For example, taking Table 6 as an example, the correspondence between the power change range and transition time capability reported by the UE shows that the maximum power change range is 30dB < ΔP <= 50dB, and the corresponding transition time value is 10μs. In this case, regardless of the actual power change range of the two uplink transmissions, the UE will adjust the power by 10μs. The transition time value will be adjusted 5μs in advance of the power switching time slot or symbol boundary.

[0143] As another possible implementation, when the terminal device performs power adjustment, it can determine the transition time value based on the reference power change range. For example, Table 6 shows the correspondence between the power change range reported by the UE and the transition time capability. Assuming the reference power change range is 20dB, the corresponding transition time value is 4μs. In this case, regardless of the actual power change range of the two uplink transmissions, the UE will adjust the power by 4μs. The transition time value will be adjusted 2μs before the power switching time slot or symbol boundary.

[0144] Based on the above embodiments, this application provides another power adjustment method, such as... Figure 6 As shown, the method may include the following steps:

[0145] S601: The terminal device reports only one transition time capability value to the network device. This transition time capability value can be one of 1μs, 2μs, 4μs, 7μs, or 10μs. The reporting method can be one transition time capability value per band, one transition time capability value per band combination, or one transition time capability value per UE. This application does not limit this method.

[0146] Furthermore, there may be a correspondence between the aforementioned at least one transition time and the subcarrier spacing (SCS) supported by the terminal device. Specifically, the correspondence may include the following situations:

[0147] (1) When the subcarrier spacing (SCS) supported by the terminal device is 15KHz, the transition time value is 7μs and 10μs.

[0148] (2) When the subcarrier spacing (SCS) supported by the terminal device is 30KHz, the transition time value is 4μs and 10μs.

[0149] (3) When the subcarrier spacing (SCS) supported by the terminal device is 60KHz, the transition time value is 2μs and 10μs.

[0150] (4) When the subcarrier spacing (SCS) supported by the terminal device is 15KHz and 30KHz, the transition time value is 7μs, 4μs and 10μs.

[0151] (5) When the subcarrier spacing (SCS) supported by the terminal device is 15KHz and 60KHz, the transition time value is 7μs, 2μs and 10μs.

[0152] (6) When the subcarrier spacing (SCS) supported by the terminal device is 30KHz and 60KHz, the transition time value is 4μs, 2μs and 10μs.

[0153] (7) When the subcarrier spacing (SCS) supported by the terminal device is 15KHz, 30KHz and 60KHz, the transition time value is 7μs, 4μs, 2μs and 10μs.

[0154] Based on the above correspondence, the terminal device can report a transition time value to the network device. For example, when the SCS supported by the terminal device is 15KHz and 30KHz, at least one transition time is 7μs, 4μs and 10μs. Then the terminal device can report any one of the three values ​​of 7μs, 4μs and 10μs to the network device.

[0155] S602: The terminal device adjusts its power based on the reported transition time value.

[0156] In one possible implementation, the first transition time value reported by the terminal device corresponds to a unique power change range. Assuming the unique power change range corresponding to the reported transition time value is the first power change range, then the corresponding first power change range in this application may include the following cases:

[0157] The first scenario: The first power variation range is the preset power variation range during the test, for example, it can be 20dB.

[0158] The second scenario: The first power variation range is the maximum power variation range among at least one power variation range, for example, it can be 50dB.

[0159] The third scenario: The first power variation range is a reference value within the power variation range. This reference value is a pre-agreed reference value or a reference value configured by the network device for the terminal device. As an example, this reference value can be the power variation range corresponding to a high-power scenario, such as 30dB.

[0160] Furthermore, in this application, the terminal device can calculate the transition time for other power change ranges based on the reported first transition time value and the corresponding power change range. The calculation process is explained below for the above three situations.

[0161] Scenario 1: Assuming the power change range is 20dB, the transition time increases by X μs for every 10dB change in power. For example, if the transition time is 4 μs for a power change range of 20dB, then the transition time for a power change range of 30dB is (4+X) μs.

[0162] The second scenario: Assuming the power change range is the maximum power change range, for example, 55dB, then the corresponding transition time value is 7μs.

[0163] The third scenario: Assuming the power variation range is a reference value, the transition time is ±Y μs for every 10dB change in the power variation range. For example, assuming the reference value for the power variation range is 30dB, the corresponding transition time is 4μs. Then, when the power variation range is 20dB, the corresponding transition time is (4-Y)μs; and when the power variation range is 50dB, the corresponding transition time is (4+2Y)μs.

[0164] It should be noted that the values ​​of X and Y in the above transition time values ​​can be agreed upon in advance through the protocol or reported through capability information. In this application, the magnitude of X and Y is not limited.

[0165] Based on the above three scenarios, the terminal device can determine the transition time corresponding to the actual power change range based on the actual power change range and the correspondence between the transition time value reported by the terminal and the power change range, and then adjust the power according to the determined transition time value.

[0166] In one possible implementation, when the terminal device adjusts the power according to the transition time value, it can determine the second transition time value corresponding to the second power change range based on the second power change range and the correspondence between the power change range and the first transition time value. Then, the terminal device evenly distributes the second transition time value at the boundary of the two symbols or time slots where the power adjustment is performed.

[0167] It is understandable that the second power variation range can be interpreted as the power variation range of the two actual uplink transmissions.

[0168] Assuming that the power adjustment occurs between two long time slots, the following examples from the three cases described in this embodiment will be used to illustrate the allocation of the corresponding transition time values ​​during actual power adjustment.

[0169] In the first scenario: when the power change range is 30dB, the transition time is (4+X)μs. The UE can then evenly distribute (4+X)μs at the boundary of the two long time slots. That is, (4+X)μs occupies (4+X) / 2μs at the boundary of each of the two long time slots, and the UE performs the power change (4+X) / 2μs in advance. For example, when X=3, the transition time corresponding to a power change range of 30dB is 7μs, and the UE can perform the power change 3.5μs in advance at the boundary of the two long time slots.

[0170] The second scenario: When the power change range is 55dB, the corresponding transition time is 7μs. In this case, the UE can evenly distribute 7μs at the boundary of the two long time slots. That is, 7μs is divided into 7 / 2μs at the boundary of the two long time slots, and the UE makes the power change 3.5μs in advance.

[0171] The third scenario: When the power change range is 20dB, the corresponding transition time is (4-Y)μs. In this case, the UE can evenly distribute (4-Y)μs at the boundary of the two long time slots. That is, (4-Y)μs occupies (4-Y) / 2μs at the boundary of the two long time slots, and the UE performs the power change (4-Y) / 2μs in advance.

[0172] When the power change range is 50dB, the corresponding transition time is (4+2Y)μs. The UE can then evenly distribute (4+2Y)μs at the boundary of the two long time slots. In other words, (4+2Y)μs occupies (4+2Y) / 2μs at the boundary of the two long time slots, and the UE performs the power change (4+2Y) / 2μs in advance.

[0173] like Figure 7 The diagram shown is a flowchart of a capability reporting method provided in an embodiment of this application. (See attached diagram.) Figure 7 As shown, the method may include the following steps:

[0174] S701: The terminal device determines one or more first transition time values ​​from at least one transition time based on the power variation range.

[0175] Wherein, the at least one transition time is pre-configured or pre-agreed. The power change range includes at least one, and the power change range corresponds to the first transition time value. In this embodiment, the at least one transition time can be a pre-configured transition time or a network-pre-agreed transition time.

[0176] As an example, assuming that at least one transition time includes 1μs, 2μs, 4μs, 7μs, and 10μs, the UE can select a first transition time value from at least one transition time according to the power variation range, and then report the selected transition time value.

[0177] Assuming the transition time is 4μs when the power change range is 20dB, 4μs when the power change range is 30dB, and 7μs when the power change range is 50dB, the UE can select a first transition time value from at least one transition time based on the above power change range, i.e., select 4μs and 7μs. Then the UE reports the first transition time value of 4μs and 7μs corresponding to the power change range to the network device.

[0178] Optionally, the UE may report the correspondence between the power change range and the first transition time value to the network device.

[0179] S702: The terminal device reports capability information to the network device, the capability information including a first transition time value.

[0180] In this embodiment of the application, after the UE determines the first transition time value from at least one transition time based on the power change range, it can report the first transition time value to the network device.

[0181] Furthermore, after the terminal device reports its capability information to the network device, the terminal device can adjust its power based on the first transition time value included in the capability information.

[0182] In one possible implementation, the terminal device performs power adjustment based on a first transition time value, including: the terminal device determining a second transition time value corresponding to the second power change range based on a second power change range and the correspondence between the power change range and the first transition time value; and the terminal device evenly distributing the second transition time value at the boundary of two symbols or time slots where power adjustment is performed.

[0183] The apparatus used to implement the above method in the embodiments of this application is described below with reference to the accompanying drawings. Therefore, the content above can be used in subsequent embodiments, and repeated content will not be described again.

[0184] This application embodiment can divide the terminal device into functional units according to the above method example. For example, each function can be divided into a separate functional unit, or two or more functions can be integrated into one processing unit. The integrated unit can be implemented in hardware or as a software functional unit. It should be noted that the unit division in this application embodiment is illustrative and only represents one logical functional division. In actual implementation, there may be other division methods.

[0185] Based on the same concept as the above-described method embodiments, this application provides a power adjustment device. When using an integrated unit, such as... Figure 8 The diagram shown illustrates a possible logic structure of a power adjustment device, which can be applied to terminal equipment. (See attached diagram.) Figure 8 As shown, the power adjustment device 800 includes a transceiver unit 801 and a processing unit 802.

[0186] The transceiver unit 801 is used to report capability information to the network device. The capability information includes a first transition time value, which is the transition time value when the terminal device performs power adjustment. The first transition time value is one or more of at least one transition time, and the at least one transition time corresponds to the subcarrier spacing (SCS) supported by the terminal device. The processing unit 802 is used to perform power adjustment based on the first transition time value.

[0187] As an optional implementation, each of at least one power variation range of the terminal device corresponds to a first transition time value.

[0188] As an optional implementation, the processing unit 802 is specifically configured to perform power adjustment based on the transition time value in the following manner: determining a second transition time value corresponding to the second power change range based on the second power change range and the correspondence between the power change range and the first transition time value; the terminal device evenly distributes the second transition time value at the boundary of the two symbols or time slots where power adjustment is performed.

[0189] As an optional implementation, the second power variation range is the power variation range between two actual uplink transmissions; or the maximum power variation range among the at least one power variation range, or a reference value among the power variation ranges, wherein the reference value of the power variation range is a reference value agreed upon in the protocol or a reference value configured by the network device for the terminal device.

[0190] As an optional implementation, the at least one transition time has the following correspondence with the subcarrier spacing (SCS) supported by the terminal device in the operating frequency band:

[0191] When the subcarrier spacing (SCS) supported by the terminal device is 15 kHz, the transition time values ​​are 7 μs and 10 μs; when the subcarrier spacing (SCS) supported by the terminal device is 30 kHz, the transition time values ​​are 4 μs and 10 μs; when the subcarrier spacing (SCS) supported by the terminal device is 60 kHz, the transition time values ​​are 2 μs and 10 μs; and when the subcarrier spacing (SCS) supported by the terminal device is 15 kHz and 30 kHz, the transition time values ​​are 7 μs and 4 μs. The transition time values ​​are 7μs, 2μs, and 10μs when the subcarrier spacing (SCS) supported by the terminal device is 15kHz and 60kHz; the transition time values ​​are 4μs, 2μs, and 10μs when the subcarrier spacing (SCS) supported by the terminal device is 30kHz and 60kHz; and the transition time values ​​are 7μs, 4μs, 2μs, and 10μs when the subcarrier spacing (SCS) supported by the terminal device is 15kHz, 30kHz, and 60kHz.

[0192] When implemented in hardware, in this embodiment, the transceiver unit 801 can be a communication interface, a transmitter, a transceiver circuit, etc. The processing unit 802 can be a communication interface, a receiver, a transceiver circuit, etc. Here, "communication interface" is a general term and may include one or more interfaces.

[0193] When the transceiver unit 801 is a transmitter and the processing unit 802 is a receiver, the power adjustment device 800 involved in the embodiments of this application can be... Figure 9 The terminal device shown. (For example...) Figure 9 The image shows a terminal device 900 provided in an embodiment of this application. The terminal device 900 includes a transceiver 901, a processor 902, and a memory 903. The memory 903 stores instructions or programs, and the processor 902 executes the instructions or programs stored in the memory 903. The transceiver 901 performs the operations performed by the transceiver unit 801 in the above embodiment. The processor 902 performs the operations performed by the processing unit 802 in the above embodiment.

[0194] It should be understood that the terminal device 800 or terminal device 900 according to the embodiments of this application may correspond to Figure 5 The terminal devices shown in the embodiments, and the operations and / or functions of the various modules in terminal device 800 or terminal device 900, are respectively for implementing Figure 5 The corresponding processes in the illustrated embodiments will not be described in detail here for the sake of brevity.

[0195] like Figure 10 As shown in the diagram, this application also provides a schematic diagram of a power adjustment device, see reference. Figure 10 As shown, the device includes a transceiver unit 1001 and a processing unit 1002.

[0196] The transceiver unit 1001 is used to report capability information to the network device. The capability information includes a first transition time value, which is the transition time value when the terminal device performs power adjustment. The first transition time value is one of at least one transition time, and the at least one transition time corresponds to the subcarrier spacing (SCS) supported by the terminal device. The processing unit 1002 is used to perform power adjustment based on the first transition time value.

[0197] In one possible implementation, each of at least one power variation range of the terminal device corresponds to a first transition time value; wherein the first transition time value corresponds to the first power variation range.

[0198] In one possible implementation, the first power variation range is a preset power variation range, for example, 20dB; or the maximum power variation range among the at least one power variation range; or a reference value among the power variation ranges, wherein the reference value of the power variation range is a pre-agreed reference value or a reference value configured by the network device for the terminal device.
