Description

Technical Field

[0001] This application relates to the field of communications, and more specifically, to a method and apparatus for relaxing parameter information, a storage medium, an electronic device, and a computer program product. Background Technology

[0002] The coverage performance of wireless networks is crucial for operators, directly impacting network construction and operating costs, making it one of the most important performance parameters. In wireless networks, due to hardware limitations of terminals, their transmission power is relatively low, with uplink transmission power lower than downlink transmission power. This can easily lead to an imbalance in uplink and downlink coverage; therefore, uplink transmission often determines the coverage area.

[0003] Currently, the commercial deployment of 5G networks widely relies on mid-band frequencies such as 3.5GHz and 2.6GHz, which are known for their wide bandwidth and high capacity, providing a solid foundation for data-intensive applications. However, these bands present several challenges in uplink performance, including higher penetration loss and lower uplink duty cycle, resulting in limited uplink coverage and capacity. To address these challenges, promote the diversification of 5G services and enhance user experience, while reducing network deployment costs, improving the uplink performance of 5G networks is particularly urgent.

[0004] 5G New Radio (NR) base stations are typically equipped with massive MIMO antenna arrays. This significant increase in antenna quantity provides additional multiplexing and diversity gain for the downlink, significantly enhancing downlink data transmission rates, link stability, and coverage. However, in the uplink—data transmission from the terminal to the base station—5G uplink coverage is constrained by limitations in terminal transmit power. Furthermore, the miniaturization of terminal devices limits the number of antennas that can be integrated, preventing full utilization of the advantages of Massive MIMO technology. Combined with the asymmetry in the uplink / downlink time slot ratio in Time Division Duplex (TDD) mode, these factors exacerbate the gap in uplink / downlink coverage performance.

[0005] The limitations of uplink coverage mean that once users are outside the range of uplink signal coverage, they cannot enjoy the high-speed data services provided by the 5G network, even under ideal downlink conditions. This directly weakens the performance advantages brought by the large downlink bandwidth resources of 5G and becomes a key bottleneck restricting the comprehensive optimization of the 5G network.

[0006] There is currently no effective solution to the problem of limited uplink coverage in existing 5G technologies.

[0007] Therefore, it is necessary to improve the relevant technology to overcome the aforementioned defects. Summary of the Invention

[0034] The embodiments of this application will be described in detail below with reference to the accompanying drawings and examples.

[0035] It should be noted that the terms "first," "second," etc., in the specification, claims, and drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0036] To enhance cell coverage, it is essential to minimize the limitation on uplink transmission power. In the NR R15 and R16 standards, a new modulation scheme, π / 2-BPSK, was introduced for the uplink data channel (Physical Uplink Shared Channel, PUSCH) and control channel (Physical Uplink Control Channel, PUCCH). When using Discrete Fourier Transform spread Orthogonal Frequency Division Multiplexing (DFT-s-OFDM) for transmission, the π / 2-BPSK modulation scheme exhibits a lower peak-to-average power ratio (PAPR) compared to higher-order modulation schemes (Quadrature Phase Shift Keying (QPSK), Quadrature Amplitude Modulation (QAM), etc.). Because the dynamic range of typical power amplifiers is limited, signals with a high PAPR (Power Amplitude Reduction) are highly susceptible to entering the nonlinear region of the power amplifier, leading to nonlinear distortion, significant spectral spread interference, and in-band signal distortion, resulting in a severe degradation of the overall system performance. A lower PAPR allows for high-power transmission without saturating the power amplifier, thus significantly improving cell coverage. In terms of radio frequency (RF) aspects, this translates to a significant improvement in the maximum power reduction (MPR) of π / 2BPSK modulation.

[0037] In NR Release 17, the standardization work for NR coverage enhancement mainly focused on coverage enhancement for PUSCH, PUCCH, and the Msg3 channel in random access. Specifically, this included PUSCH repetition enhancement, multi-slot transport block processing, joint channel estimation schemes, PUCCH dynamic repetition indication, demodulation reference signal binding schemes, and repetition schemes for the Msg3 channel in random access. At the end of its work, 3GPP summarized the performance gaps between some channels and expected performance in different scenarios, as well as the gain evaluation of the enhancement schemes standardized in Release 17. According to the evaluation results of 3GPP TR 38.830, it can be seen that in some scenarios, PUCCH and PUSCH still have a certain gap from expected performance. Therefore, continuing the standardization work for coverage enhancement in Release 18 is essential.

[0038] Release 18 (R18) focuses more on enhancing the coverage of the Physical Random Access Channel (PRACH), improving dynamic uplink waveform switching, and enhancing the power domain. Specifically, it introduces a PRACH retransmission mechanism and dynamic waveform switching for DFT-S-OFDM and Cyclic Prefix Orthogonal Frequency Division Multiplexing (CP-OFDM). Power domain enhancement primarily reduces the MPR (Maximum Per Second) to increase uplink transmission power, but this is limited to inner RB allocations on a single uplink carrier. Further uplink power enhancement is constrained by out-of-band leakage metrics, such as Adjacent Channel Leakage Ratio (ACLR), Spectrum Emission Mask (SEM), and Spurious Emissions (SE). Regarding the factors limiting MPR, simulation results (as shown in Tables 1 and 2) reveal that for outer RB allocations with a small number of resource blocks (RBs), the main limiting factor is the SEM index. For outer RB allocations with a large number of RBs, the ACLR index is the main limiting factor. For edge RB allocations, the SEM index is the main limiting factor for MPR. For inner RB allocations, the EVM or IBE index is the main limiting factor for MPR. Therefore, the MPR of outer and edge RB allocations can be reduced by relaxing ACLR and / or SEM. This indicates that there is further room for improvement in uplink transmission power, and the MPR can be reduced by relaxing the out-of-band leakage index.

[0043] Therefore, this application provides a method for relaxing parameter information. The method embodiments provided in this application can be executed on terminal devices such as computer terminals. Taking running on a computer terminal as an example, Figure 1 This is a hardware structure block diagram of the computer terminal used in the embodiments of the method of this application. For example... Figure 1 As shown, a computer terminal may include one or more ( Figure 1 Only one is shown in the diagram. A processor 102 (which may include, but is not limited to, a microprocessor MCU or a programmable logic device FPGA, etc.) and a memory 104 for storing data are also shown. The computer terminal may further include a transmission device 106 for communication functions and an input / output device 108. Those skilled in the art will understand that... Figure 1 The structure shown is for illustrative purposes only and does not limit the structure of the computer terminal described above. For example, the computer terminal may also include components that are more complex than those described above. Figure 1 The more or fewer components shown, or having the same Figure 1 The different configurations shown.

[0044] The memory 104 can be used to store computer programs, such as application software programs and modules, like the computer program corresponding to the parameter information relaxation method in this embodiment. The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, thus implementing the above-described method. The memory 104 may include high-speed random access memory and may also include non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some instances, the memory 104 may further include memory remotely located relative to the processor 102, and these remote memories can be connected to a computer terminal via a network. Examples of such networks include, but are not limited to, the Internet, corporate intranets, local area networks, mobile communication networks, and combinations thereof.

[0045] The transmission device 106 is used to receive or send data via a network. Specific examples of the network described above may include a wireless network provided by a communication provider for the computer terminal. In one example, the transmission device 106 includes a Network Interface Controller (NIC), which can connect to other network devices via a base station to communicate with the Internet. In another example, the transmission device 106 may be a Radio Frequency (RF) module used for wireless communication with the Internet.

[0046] This embodiment provides a method for relaxing parameter information running on a computer terminal. Figure 2This is a flowchart of a method for relaxing parameter information according to an embodiment of this application, such as... Figure 2 As shown, the process includes the following steps:

[0047] Step S202: Determine whether to relax the adjacent channel leakage ratio and / or spectrum leakage template of the terminal according to the target rule;

[0048] Step S204: If it is determined that the adjacent channel leakage ratio and / or spectrum leakage template of the terminal are to be relaxed, the target parameter information of the terminal is relaxed, wherein the target parameter information includes at least one of the following: the value of the adjacent channel leakage ratio, the value of the spectrum leakage template, the application range of the adjacent channel leakage ratio, and the application range of the spectrum leakage template.

[0049] Through the above embodiments of this application, since the adjacent channel leakage ratio and / or spectrum leakage template of the terminal are instructed to relax the value of the adjacent channel leakage ratio and / or the value of the spectrum leakage template and / or the application range of the adjacent channel leakage ratio and / or the application range of the spectrum leakage template when it is determined that the adjacent channel leakage ratio and / or the spectrum leakage template of the terminal need to be relaxed, the problem of limited 5G uplink coverage can be solved, thereby achieving the effect of improving 5G uplink coverage.

[0050] The entity performing the above steps can be a terminal, but is not limited to this.

[0051] Optionally, to better understand step S202 above, this application embodiment provides an implementation method: determining the location of the terminal and whether its operator allows relaxation of the adjacent channel leakage ratio and / or spectrum leakage template based on the terminal's public land mobile network information; determining whether the tracking area where the terminal is located allows relaxation of the terminal's adjacent channel leakage ratio and / or spectrum leakage template based on the terminal's public land mobile network information and tracking area code information; determining whether to relax the terminal's adjacent channel leakage ratio and / or spectrum leakage template based on the terminal's current frequency band information; determining whether to relax the terminal's adjacent channel leakage ratio and / or spectrum leakage template based on the terminal's measurement results, wherein the measurement results are measurement results used to indicate reference signal received power and / or reference signal received quality and / or signal-to-interference-plus-noise ratio; and determining whether to relax the terminal's adjacent channel leakage ratio and / or spectrum leakage template based on the base station's indication information.

[0052] In the embodiments of this application, the regulations of the country or region where the terminal UE is located and the policies of the operator to which it belongs are taken into consideration. The operator may decide whether to allow the relaxation of ACLR and SEM of the UE according to local spectrum management regulations and its own network resource planning, so as to adapt to different network environments and service needs.

[0053] Tracking Area Code (TAC) is used to identify tracking areas within a network, allowing the network to know the approximate location of the UE. By combining PLMN information and TAC, it is possible to more accurately determine whether the specific tracking area where the UE is located allows for the relaxation of ACLR and SEM.

[0054] The physical characteristics of different frequency bands affect ACLR and SEM requirements. For some frequency bands, such as high-frequency millimeter waves, relaxing ACLR and SEM restrictions may have a smaller impact on network performance, while in low-frequency bands, relaxing restrictions may require more caution. Therefore, the network will decide whether to relax ACLR and SEM standards based on the frequency band currently used by the UE.

[0055] The UE periodically measures the quality of its received signals, including Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), and Signal to Interference and Noise Ratio (SINR). These data reflect the connectivity and channel quality between the UE and the base station. When these measurements indicate that the UE is at the network edge or has poor signal quality, the network may decide to relax the ACLR and SEM restrictions to increase the UE's uplink power, thereby improving uplink coverage.

[0056] In some cases, the base station will proactively instruct the UE whether to relax ACLR and SEM. This may be based on considerations of overall network performance, such as when network load is low or when there is a need for performance optimization in a specific frequency band, the base station may decide to adjust the ACLR and SEM restrictions for the UE.

[0057] It should be noted that when the base station instructs the terminal whether to relax the adjacent channel leakage ratio and / or spectrum leakage template of the terminal, the base station needs to implement the following scheme:

[0058] Based on the terminal's public land mobile network information, determine whether the location of the terminal and its operator allow the relaxation of the terminal's adjacent channel leakage ratio and / or spectrum leakage template; based on the terminal's public land mobile network information and tracking area code information, determine whether the tracking area where the terminal is located allows the relaxation of the terminal's adjacent channel leakage ratio and / or spectrum leakage template; based on the terminal's current frequency band information, determine whether to relax the terminal's adjacent channel leakage ratio and / or spectrum leakage template; based on the terminal's measurement results, determine whether to relax the terminal's adjacent channel leakage ratio and / or spectrum leakage template, wherein the measurement results are measurements used to indicate reference signal received power and / or reference signal received quality and / or signal-to-interference-plus-noise ratio.

[0059] Optionally, if the terminal relaxes the adjacent channel leakage ratio and / or spectrum leakage template of the terminal, it is necessary to report the information that the terminal has relaxed the adjacent channel leakage ratio and / or spectrum leakage template to the base station.

[0060] In this embodiment, the decision to relax ACLR and SEM restrictions is based on the UE's location, operator policies, current frequency band conditions, and signal quality measurement results. This aims to improve the UE's uplink performance, especially coverage and data transmission capacity, as much as possible without affecting the performance of adjacent channels and the overall network, thus providing users with a better communication experience.

[0061] Optionally, determining whether to relax the adjacent channel leakage ratio and / or spectrum leakage template of the terminal based on the measurement results of the terminal includes: relaxing the adjacent channel leakage ratio and / or spectrum leakage template of the terminal when the reference signal received power is less than or equal to a preset reference signal received power, and / or the reference signal received quality is less than or equal to a preset reference signal received quality, and / or the signal-to-interference-plus-noise ratio is less than or equal to a preset signal-to-interference-plus-noise ratio; and not relaxing the adjacent channel leakage ratio and / or spectrum leakage template of the terminal when the reference signal received power is greater than a preset reference signal received power, the reference signal received quality is greater than a preset reference signal received quality, and the signal-to-interference-plus-noise ratio is greater than a preset signal-to-interference-plus-noise ratio.

[0062] It should be noted that when the RSRP measured by the UE is lower than or equal to a preset threshold, this usually means that the distance between the UE and the base station is too far or the channel conditions are poor, resulting in insufficient signal strength to maintain a high-quality link. In this case, the network may decide to relax the ACLR and SEM restrictions of the UE, allowing the UE to use higher power in the uplink direction, thereby improving its signal coverage and link quality.

[0063] Similarly, when the RSRQ measured by the UE is lower than or equal to a preset threshold, it indicates that the signal quality received by the UE is poor, and there may be a lot of interference and noise. Relaxing the ACLR and SEM restrictions helps the UE overcome these unfavorable channel conditions, improves link reliability by increasing uplink power, and thus improves communication quality.

[0064] Similarly, if the UE's SINR is lower than or equal to a preset threshold, it indicates that the signal is experiencing high levels of interference and noise, leading to a decrease in the reliability of communication between the UE and the base station. Relaxing ACLR and SEM allows the UE to use higher transmit power, which helps overcome these interferences, improves the link's SINR, and thus enhances uplink performance.

[0065] In another scenario, if RSRP, RSRQ, and SINR are all higher than preset thresholds, it may indicate that although the UE receives a reasonably strong signal, the link quality remains poor due to high interference and noise levels. In this case, the network will choose not to relax ACLR and SEM restrictions.

[0066] Through the above mechanism, the network can dynamically adjust its uplink parameters according to the actual signal quality of the UE to achieve optimal coverage and capacity, while minimizing interference to adjacent channels and protecting the overall network performance.

[0067] Optionally, the measurement results include one of the following: physical layer measurement results, or upper layer measurement results.

[0068] The physical layer is the lowest layer of the wireless communication protocol stack, responsible for handling signal transmission and reception. In communication standards such as 5G NR, physical layer measurements include, but are not limited to: Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), and Signal-to-Interference-plus-Noise Ratio (SINR). These are obtained directly from the physical characteristics of the signal and can reflect the current quality of the channel between the UE and the base station in real time.

[0069] Higher-layer measurements typically refer to measurements performed at protocol layers above the physical layer, such as the MAC layer, RLC layer, PDCP layer, or RRC layer. Higher-layer measurements include, but are not limited to, Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), and Signal-to-Interference-plus-Noise Ratio (SINR). Higher-layer measurements often provide a more comprehensive perspective on network performance and UE service experience.

[0070] Optionally, determining whether to relax the adjacent channel leakage ratio and / or spectrum leakage template of the terminal based on the indication information of the base station includes one of the following: determining whether to relax the adjacent channel leakage ratio and / or spectrum leakage template of the terminal based on the radio resource control signaling of the base station; determining whether to relax the adjacent channel leakage ratio and / or spectrum leakage template of the terminal based on the media access control control element of the base station; or determining whether to relax the adjacent channel leakage ratio and / or spectrum leakage template of the terminal based on the downlink control information of the base station.

[0071] In other words, the base station's indication to the UE includes at least one of the following:

[0072] The terminal is instructed to relax ACLR and SEM by Radio Resource Control (RRC) signaling;

[0073] The base station instructs the terminal to relax ACLR and SEM through a MAC Control Element (MAC CE). This instruction process takes one of two forms:

[0074] 1) Introduce a new field in the existing MAC CE to send relaxation messages;

[0075] 2) Create a brand new MAC CE specifically for relaxation instructions for ACLR and SEM.

[0076] ACLR and SEM relaxation are performed via Downlink Control Information (DCI) terminals;

[0077] This instruction mechanism also provides two options:

[0078] 1) Add a field to the existing DCI format to describe relaxation details.

[0079] 2) Develop a new DCI format specifically for sending ACLR and SEM relaxation information.

[0080] In the embodiments of this application, the base station transmits instructions regarding ACLR and SEM relaxation to the UE through various means such as RRC signaling, MAC CE, and DCI. These mechanisms collectively ensure that the UE can maximize its uplink performance while maintaining reasonable adjacent channel interference and signal quality, achieving longer coverage and more stable communication.

[0081] Optionally, when the indication information indicates a value for instructing the terminal to relax the adjacent channel leakage ratio and / or the spectrum leakage template value, the indication information includes at least one of the following: whether to relax the adjacent channel leakage ratio and / or the spectrum leakage template value; the relaxation value of the adjacent channel leakage ratio; the relaxation value of the spectrum leakage template; the relaxation value of the adjacent channel leakage ratio and the relaxation value of the spectrum leakage template; and the maximum power back-off value of external resource block allocation and edge resource block allocation when relaxing the adjacent channel leakage ratio and / or the spectrum leakage template.

[0082] It should be noted that when the base station instructs the terminal to relax the value of the adjacent channel leakage ratio and / or the value of the spectrum leakage template, the instruction content may be at least one of the following: indicating whether to relax ACLR and / or SEM; relaxation value of ACLR; relaxation value of SEM; relaxation values ​​of ACLR and SEM; MPR values ​​of outer RB allocations and edge RB allocations after relaxing ACLR and / or SEM.

[0083] It should be noted that when the base station notifies the UE about ACLR and SEM relaxation, the content includes, but is not limited to:

[0084] RelaxIndicator: A 2-bit field indicating whether ACLR and / or SEM relaxation has been performed. The specific encoding is as follows:

[0085] 00: Do not perform any relaxation procedures;

[0086] 01: Only relax ACLR;

[0087] 10: Only relax SEM;

[0088] 11: Relax ACLR and SEM simultaneously;

[0089] ACLR-RelaxValue: Specifically indicates the degree of ACLR relaxation, measured in decibels (dB).

[0090] SEM-RelaxValue: Specifically indicates the degree of relaxation in SEM, also measured in decibels (dB).

[0091] MPR-OuterValue: Indicates the MPR value under the outer RB allocation after ACLR and / or SEM relaxation, in dB.

[0092] MPR-EdgeValue: After ACLR and / or SEM relaxation, indicates the MPR value under the edge RB allocation, in dB.

[0093] Optionally, when the indication information is used to instruct the terminal to relax the application range of the adjacent channel leakage ratio and / or the application range of the spectrum leakage template and / or the value of the adjacent channel leakage ratio and / or the value of the spectrum leakage template, the indication information includes at least one of the following: whether to relax the application range of the adjacent channel leakage ratio and / or the application range of the spectrum leakage template and / or the value of the adjacent channel leakage ratio and / or the value of the spectrum leakage template; the size of the adjusted channel bandwidth of the terminal; the relaxation value of the adjacent channel leakage ratio; the relaxation value of the spectrum leakage template; the relaxation value of the adjacent channel leakage ratio and the relaxation value of the spectrum leakage template; the maximum power backoff value of external resource block allocation and edge resource block allocation when relaxing the adjacent channel leakage ratio and / or the spectrum leakage template; the offset between the first resource block of the terminal's current channel bandwidth and the first resource block of the terminal's adjusted channel bandwidth.

[0094] It should be noted that the base station sends instructions to the UE regarding the scope and specific relaxation values ​​of ACLR and SEM using at least one of the following methods:

[0095] RelaxIndicator: A 2-bit control field indicating the relaxation type. The specific encoding definitions are as follows: 00: No relaxation operation performed. 01: Relax only the ACLR or SEM value, application scope remains unchanged. 10: Expand the application scope of both ACLR and SEM, value remains unchanged. 11: Relax both ACLR and SEM values ​​and application scope simultaneously.

[0096] NewBandwidth: The size of the channel bandwidth adjusted by the terminal (second bandwidth). The second bandwidth is typically twice the terminal's current channel bandwidth (first bandwidth) and is used for a wider range of ACLR and SEM applications to facilitate a reduction in maximum power back-off (MPR). This field needs to be used in conjunction with the RelaxIndicator. When the RelaxIndicator indicates 10 or 11, if this field is not empty, the UE uses the second bandwidth to apply ACLR and SEM indicators. If this field is empty, the UE defaults to using the BS channel bandwidth to apply ACLR and SEM indicators.

[0097] ACLR-RelaxValue: Indicates the ACLR relaxation value in dB. This field is used in conjunction with the RelaxIndicator and is valid when the RelaxIndicator indicates 01 or 11.

[0098] SEM-RelaxValue: Indicates the SEM relaxation value in dB. This field needs to be used in conjunction with RelaxIndicator and is effective when RelaxIndicator indicates 01 or 11.

[0099] MPR-OuterValue: Indicates the expected MPR value under outer resource block allocations after ACLR and SEM relaxation, in dB.

[0100] MPR-EdgeValue: Indicates the expected MPR value under edge resource block allocations after ACLR and SEM relaxation, in dB.

[0101] OffsetIndicator: Indicates the offset between the first RB of the first bandwidth and the first RB of the second bandwidth.

[0102] Through the aforementioned mechanism, the base station can provide the UE with fine-grained ACLR and SEM relaxation strategies, including the scope of relaxation (adjustment of frequency bandwidth), the specific degree of relaxation (relaxation value in dB), and the expected maximum power back-off (MPR) value after relaxation. The RelaxIndicator, combining NewBandwidth, ACLR-RelaxValue, SEM-RelaxValue, and MPR values, provides the UE with a complete guidance scheme to adapt to power control requirements in different scenarios. This control mechanism ensures that the UE can improve uplink performance while avoiding excessive interference to adjacent channels, optimizing the user's communication experience in different areas, especially at coverage edges and in capacity-constrained areas, contributing to higher quality connections and wider coverage.

[0103] Optionally, the application range of the adjacent channel leakage ratio and / or the application range of the spectrum leakage template are determined based on the channel bandwidth adjusted by the terminal.

[0104] It should be noted that the adjusted channel bandwidth of the terminal is used for applying ACLR and SEM indicators, not for transmitting data. That is, the application range of the UE's ACLR and SEM indicators starts from the edge of the adjusted channel bandwidth, and the channel bandwidth used for transmitting data is still the previous channel bandwidth (i.e., the current channel bandwidth).

[0105] Optionally, embodiments of this application provide a method for determining the adjusted channel bandwidth of a terminal: determining the distance between the edge of the current channel bandwidth of the terminal and the edge of the current channel bandwidth of the base station; determining whether the distance is greater than or equal to half of the current channel bandwidth of the terminal; if the distance is greater than or equal to half of the current channel bandwidth of the terminal, determining that the adjusted channel bandwidth of the terminal is twice the current channel bandwidth of the terminal, wherein the center frequency points of the current channel bandwidth of the terminal and the adjusted channel bandwidth of the terminal are the same; if the distance is less than half of the current channel bandwidth of the terminal, determining that the adjusted channel bandwidth of the terminal is the current channel bandwidth of the base station.

[0106] In this embodiment, the distance between the edge of the UE's current channel bandwidth and the edge of the base station's channel bandwidth is calculated. Next, the measured edge distance is compared to see if it is greater than or equal to half of the UE's current channel bandwidth. When the edge distance is greater than or equal to half of the current channel bandwidth, the UE's channel bandwidth is adjusted to twice its current channel bandwidth. When the edge distance is less than half of the current channel bandwidth, the adjusted channel bandwidth of the UE is equal to the base station's current channel bandwidth.

[0107] Through the above decision-making process, the network can intelligently assess the relative frequency position of the UE and the base station, as well as the potential impact of the UE's uplink on adjacent channels, thereby deciding whether and how to adjust the UE's channel bandwidth to achieve the dual goals of optimizing uplink performance and reducing adjacent channel interference.

[0108] Optionally, before determining the distance between the edge of the current channel bandwidth of the terminal and the edge of the current channel bandwidth of the base station, the method further includes: when the base station performs downlink transmission through a single carrier, determining the current channel bandwidth of the base station as the bandwidth of the single carrier; when the base station performs downlink transmission through multiple consecutive carriers in a frequency band, determining the current channel bandwidth of the base station as the aggregated bandwidth of the multiple consecutive carriers.

[0109] When a base station uses a single carrier for downlink data transmission, the current channel bandwidth of the base station is determined as the bandwidth of its single carrier.

[0110] When a base station performs downlink transmission using multiple consecutive carriers within the same frequency band, its current channel bandwidth is defined as the aggregate bandwidth of these consecutive carriers. In other words, the base station's total downlink bandwidth is the sum of the bandwidths of all consecutive carriers, thus providing a more comprehensive view of spectrum usage.

[0111] Optionally, before determining the distance between the edge of the current channel bandwidth of the terminal and the edge of the current channel bandwidth of the base station, the method further includes: when the base station performs downlink transmission using a single carrier, determining the frequency domain reference point of the base station and the offset of the single carrier relative to the frequency domain reference point of the base station, and determining the lower edge frequency point of the current channel bandwidth of the base station based on the offset of the frequency domain reference point of the base station and the single carrier bandwidth; when the base station performs downlink transmission using multiple consecutive carriers within a frequency band, determining the frequency domain reference point of the base station and the offset of each carrier relative to the frequency domain reference point of the base station, and determining the current channel bandwidth of the base station based on the minimum value among the offsets corresponding to the frequency domain reference point of the base station and the multiple consecutive carriers. The lower edge frequency point; when the base station performs downlink transmission using a single carrier, the upper edge frequency point of the current channel bandwidth of the base station is determined based on the lower edge frequency point of the base station and the current channel bandwidth of the base station; when the base station performs downlink transmission using multiple consecutive carriers within a frequency band, the frequency domain reference point of the base station, the offset of each carrier relative to the frequency domain reference point of the base station, and the bandwidth of each carrier are determined, and the upper edge frequency point of each carrier is determined based on the frequency domain reference point of the base station, the offset of each carrier relative to the frequency domain reference point of the base station, and the bandwidth of each carrier; the maximum value among the upper edge frequency points corresponding to the multiple consecutive carriers is determined as the upper edge frequency point of the current channel bandwidth of the base station.

[0112] This application provides a method for determining the lower and upper edge frequency points of a base station channel bandwidth, including:

[0113] When a base station performs downlink transmission using a single carrier, the frequency domain reference point of the base station and the offset of the single carrier relative to that reference point are first determined. When a base station uses multiple consecutive carriers for downlink transmission, the frequency domain reference point of the base station and the offset of each carrier relative to the reference point are also determined, but the minimum value among all carrier offsets is selected as the basis for subsequent calculations.

[0114] In single-carrier mode, the lower edge frequency of the base station channel bandwidth can be calculated by combining the known frequency domain reference point and the offset information of a single carrier. In multi-carrier mode, the precise location of the lower edge of the base station channel bandwidth is determined using the frequency domain reference point and the smallest offset among multiple carriers.

[0115] For single-carrier transmission, the upper edge frequency point of the base station is directly calculated from the lower edge frequency point and the current channel bandwidth of the base station. However, in the case of multi-carrier aggregation, the upper edge frequency point of the base station needs to be obtained by considering the frequency domain reference point, offset, and bandwidth of each carrier, and determining the maximum value among all the upper edge frequency points of all carriers.

[0116] Through the above steps, the base station can accurately define the upper and lower edge frequency points of its current channel bandwidth, regardless of whether it is a single-carrier or multi-carrier aggregation transmission scenario. This is fundamental for subsequently determining the distance between the UE and the edge of the base station's channel bandwidth, and for formulating UE uplink power control strategies (such as relaxing ACLR and SEM) based on this distance. Precise frequency point definition helps the UE better understand its frequency position in the network and the potential impact of its uplink on adjacent channels, thereby enabling smarter and more accurate power adjustment and interference management, ultimately improving the spectral efficiency and network performance of the entire system.

[0117] Optionally, before determining the distance between the edge of the current channel bandwidth of the terminal and the edge of the current channel bandwidth of the base station, the method further includes: determining the frequency domain reference point of the terminal and the offset of the terminal's carrier relative to the frequency domain reference point of the terminal; determining the lower edge frequency point of the current channel bandwidth of the terminal based on the frequency domain reference point of the terminal and the offset of the terminal's carrier relative to the frequency domain reference point of the terminal; and determining the upper edge frequency point of the current channel bandwidth of the terminal based on the lower edge frequency point of the terminal and the current channel bandwidth of the terminal.

[0118] This application provides a scheme for accurately determining the edge frequency point of the current channel bandwidth of a UE, including:

[0119] Determine the frequency domain reference point for the UE. Then, determine the offset of the UE carrier relative to the frequency domain reference point. This offset reflects the distance between the actual frequency used by the UE carrier and the reference point.

[0120] After determining the frequency domain reference point and carrier offset of the UE, the lower edge frequency point of the UE's current channel bandwidth (UE channel bandwidth, or UE CBW for short) can be calculated.

[0121] Given the lower edge frequency point of the UE, the upper edge frequency point of the UE CBW can be calculated by combining the current channel bandwidth of the UE.

[0122] Optionally, determining the distance between the edge of the current channel bandwidth of the terminal and the edge of the current channel bandwidth of the base station includes: determining the distance between the lower edge frequency point of the current channel bandwidth of the terminal and the lower edge frequency point of the current channel bandwidth of the base station; and determining the distance between the upper edge frequency point of the current channel bandwidth of the terminal and the upper edge frequency point of the current channel bandwidth of the base station.

[0123] In this embodiment, the distance between the lower edge frequency point of the UE's current channel bandwidth and the lower edge frequency point of the base station's current channel bandwidth is calculated. This distance reflects the interval between the UE's minimum frequency usage range and the lower limit of the base station's frequency resources.

[0124] The distance between the upper edge frequency point of the UE's current channel bandwidth and the upper edge frequency point of the base station's current channel bandwidth is measured. Similar to the lower edge distance, the upper edge distance provides information about the interval between the UE's highest frequency usage range and the base station's frequency resource limit.

[0125] The calculated lower and upper edge distances together form the basis for evaluating the spectrum usage of the UE and the base station. By comparing these two distances with half of the UE's current channel bandwidth, it can be determined whether the UE's CBW is sufficiently far from the edge of the BS, and thus decide whether it is appropriate to expand the UE's channel bandwidth or relax ACLR and SEM restrictions.

[0126] Optionally, the adjusted internal resource block allocation of the terminal is determined based on the adjusted channel bandwidth of the terminal, wherein the adjusted internal resource block allocation is the intersection of the resource block allocation of the current channel bandwidth of the terminal and the internal resource block allocation of the adjusted channel bandwidth of the terminal.

[0127] Optionally, determining the adjusted internal resource block allocation of the terminal based on the adjusted channel bandwidth includes: determining the lower and upper limits of the starting position of the internal resource blocks of the terminal based on the adjusted channel bandwidth of the terminal; determining whether the resource block allocation of the terminal meets preset conditions; and if the resource block allocation meets the preset conditions, determining the resource block allocation as the adjusted internal resource block allocation of the terminal, wherein the preset conditions include: RB Start,Low ≤RB Start ≤RB Start,High ;RB shift ≤RB Start ≤N RB +RB shift ;RB Start ≤N RB +RB shift -L CRB L CRB ≤ceil(N RB,extended / 2), where RB Start,Low RB is the lower limit of the starting position of the adjusted internal resource block allocation for the terminal. Start The starting position allocated to the resource block, RB Start,High The upper limit of the starting position of the adjusted internal resource block allocation for the terminal, RB shift N is the offset between the first resource block of the current channel bandwidth of the terminal and the first resource block of the adjusted channel bandwidth. RB Configure the maximum transmission bandwidth of the current channel bandwidth of the terminal, L CRB The size N allocated to the resource blocks of the terminal.RB,extended Configure the maximum transmission bandwidth for the adjusted channel bandwidth of the terminal.

[0128] Optionally, determining the lower and upper limits of the starting position of the adjusted internal resource block of the terminal based on the adjusted channel bandwidth of the terminal includes:

[0129] RB Start,Low =max(1,floor(L) CRB / 2)), where max() represents the maximum value of all parameters, floor(x) represents the largest integer less than or equal to x, and L CRB This represents the current number of contiguous resource blocks of the terminal.

[0130] RB Start,High =N RB,extended –RB Start,Low –L CRB .

[0131] The resource block allocation (RB allocation) at this time is the inner RB allocation of the adjusted channel bandwidth (second bandwidth) when the following conditions are met:

[0132] RB Start,Low ≤RB Start ≤RB Start,High ,andL CRB ≤ceil(N RB,extended / 2).

[0133] Where ceil(x) is the smallest integer greater than or equal to x. CRB It is the size of the resource block allocation for the terminal, RB Start,Low and RB Start,High It is the starting RB (RB) of the adjusted internal resource block allocation. Start (i.e., the starting position of resource block allocation in the above embodiments) upper and lower limits. N RB,extended This is the maximum transmission bandwidth configuration for the second bandwidth.

[0134] The new inner RB allocation for the current channel bandwidth (first bandwidth) must also meet the following conditions:

[0135] RB shift ≤RB Start ≤N RB +RB shift ;

[0136] Among them, RB shift It is the offset between the first RB of the first bandwidth and the first RB of the second bandwidth, N. RBIt is the maximum transmission bandwidth configuration of the first bandwidth.

[0137] In addition, such as Figure 4 As shown, the new inner RB allocation should be located in the region below the hypotenuse of the right triangle of the first bandwidth RB allocation, which can be expressed by the following formula:

[0138] RB Start -RB shift +L CRB ≤N RB ;

[0139] RB can be launched Start ≤N RB +RB shift -L CRB ;

[0140] Therefore, the new inner RB allocation for the first bandwidth can be defined as:

[0141] RB Start,Low =max(1,floor(L) CRB / 2));

[0142] RB Start,High =N RB,extended –RB Start,Low –L CRB ;

[0143] The RB allocation at this time is the new inner RB allocation of the first bandwidth when the following conditions are met:

[0144] RB Start,Low ≤RB Start ≤RB Start,High and,

[0145] RB shift ≤RB Start ≤N RB +RB shift and,

[0146] RB Start ≤N RB +RB shift -L CRB and,

[0147] L CRB ≤ceil(N RB,extended / 2).

[0148] To better understand the process of the above parameter information relaxation method, the implementation flow of the above parameter information relaxation method will be described below in conjunction with optional embodiments, but it is not intended to limit the technical solution of the embodiments of this application.

[0149] Optionally, for certain specific scenarios, the MPR can be reduced by relaxing ACLR and / or SEM values. This embodiment provides a method for relaxing ACLR and / or SEM values, as follows:

[0150] Step 11: The base station determines whether to send an instruction to the terminal (UE) to relax ACLR and / or SEM based on at least one of the following methods:

[0151] a) Based on the Public Land Mobile Network (PLMN) information where the UE is located, confirm whether the country and operator allow the relaxation of ACLR and / or SEM.

[0152] b) Based on the PLMN and Tracking Area Code (TAC) information, determine whether the tracking area where the UE is located meets the conditions for relaxing ACLR and / or SEM.

[0153] c) Based on the current frequency band characteristics, assess whether it is appropriate to relax ACLR and / or SEM.

[0154] d) Evaluate the UE-reported Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), or Signal-to-Noise Ratio Plus Interference Ratio (SINR) measurements. If any of these measurements fall below a set threshold, trigger ACLR relaxation and / or SEM relaxation. The measurement results can be based on either Layer 1 or Layer 3.

[0155] Step 12: The base station sends an instruction to the UE to relax ACLR and / or SEM in at least one of the following ways:

[0156] a) Using Radio Resource Control (RRC) signaling, the indication includes at least one of the following:

[0157] Indicates whether to relax ACLR and / or SEM; relaxation value of ACLR; relaxation value of SEM; relaxation values ​​of ACLR and SEM; MPR values ​​of outer and edge RB allocations after relaxing ACLR and / or SEM.

[0158] Add at least one of the following fields to the RRC signaling:

[0159] RelaxIndicator: 2 bits, 00 indicates no relaxation, 01 indicates ACLR relaxation, 10 indicates SEM relaxation, 11 indicates both ACLR and SEM relaxation.

[0160] ACLR-RelaxValue: Indicates the ACLR relaxation value, in dB;

[0161] SEM-RelaxValue: Indicates the SEM relaxation value, in dB;

[0162] MPR-OuterValue: Indicates the MPR value of outer RB allocations after ACLR and / or SEM relaxation, in dB;

[0163] MPR-EdgeValue: Indicates the MPR value of edge RB allocations after ACLR and / or SEM relaxation, in dB.

[0164] b) Instructions via Media Access Control Element (MAC CE), specifically in two ways: either adding fields to an existing MAC CE, or adding a new MAC CE. The instruction content can be at least one of the following:

[0165] Indicates whether to relax ACLR and / or SEM; relaxation value of ACLR; relaxation value of SEM; relaxation values ​​of ACLR and SEM; MPR values ​​of outer and edge RB allocations after relaxing ACLR and / or SEM.

[0166] c) Utilize downlink control information (DCI) indications, specifically in two ways: one is to add some fields to the existing DCI, and the other is to add a new DCI. The indication content can be at least one of the following: indicating whether ACLR and / or SEM are relaxed; the relaxation value of ACLR; the relaxation value of SEM; the relaxation values ​​of ACLR and SEM; the MPR values ​​of outer and edgeRB allocations after relaxing ACLR and / or SEM.

[0167] This application verifies the specific effect of adjusting ACLR and / or SEM values ​​on MPR reduction through simulation. The simulation is conducted on UEs with a specific power level (PC3), using DFT-s-OFDM and CP-OFDM waveforms, and QPSK and 16QAM modulation schemes. Channel bandwidths of 5MHz, 15MHz, 20MHz, 50MHz, 80MHz, and 100MHz were selected. The simulation shows the MPR reduction achievable by outer RB allocation when ACLR is relaxed by 1dB and 2dB. Simulations also show the MPR reduction achievable by outer RB allocation when both ACLR and SEM are relaxed by 1dB and 2dB. Simulation results indicate that when the number of RBs occupied by outer RB allocation is large, ACLR is the main limiting factor for MPR. In this case, relaxing ACLR by 1dB yields approximately 0.3dB of MPR reduction for DFT-s-OFDM and approximately 0.4dB of MPR reduction for CP-OFDM. Relaxing ACLR by 2dB results in approximately a 0.6dB reduction in MPR for DFT-s-OFDM and approximately a 0.73dB reduction for CP-OFDM. When the number of RBs occupied by the outer RB allocation is small, both ACLR and SEM can be limiting factors for MPR. Relaxing both ACLR and SEM by 1dB results in approximately a 0.4dB reduction in MPR for DFT-s-OFDM and approximately a 0.4dB reduction for CP-OFDM. Relaxing both ACLR and SEM by 2dB results in approximately a 0.5dB reduction in MPR for DFT-s-OFDM and approximately a 0.6dB reduction for CP-OFDM.

[0168] Based on simulation results, for PC3-level UEs, if ACLR and SEM are relaxed by 1dB simultaneously, the MPR of outer RB allocations corresponding to DFT-s-OFDMQPSK can be reduced to 0.6dB, the MPR of outer RB allocations corresponding to DFT-s-OFDM 16QAM can be reduced to 1.6dB, the MPR of outer RB allocations corresponding to CP-OFDM QPSK can be reduced to 2.6dB, and the MPR of outer RB allocations corresponding to CP-OFDM 16QAM can be reduced to 2.6dB. If ACLR and SEM are relaxed by 2dB simultaneously, the MPR of outer RB allocations for DFT-s-OFDM QPSK can be reduced to 0.5dB, the MPR of outer RB allocations for DFT-s-OFDM 16QAM can be reduced to 1.5dB, the MPR of outer RB allocations for CP-OFDM QPSK can be reduced to 2.4dB, and the MPR of outer RB allocations for CP-OFDM 16QAM can be reduced to 2.4dB.

[0169] Optionally, in specific scenarios, uplink maximum power backoff can be reduced by expanding the application scope (sum) of adjacent channel leakage ratio and spectrum leakage template, thereby optimizing uplink transmission performance. This embodiment provides a method for relaxing the application scope (sum) of ACLR and / or SEM, as follows:

[0170] Step 21: The base station decides whether to issue ACLR and SEM relaxation instructions to the UE based on at least one of the following strategies:

[0171] a) Based on Public Land Mobile Base Station (PLMN) information, confirm whether the geographical location of the UE and the regulations of its operator allow for the relaxation of ACLR and SEM.

[0172] b) Combine PLMN and Tracking Area Code (TAC) to analyze the environmental factors in the tracking area where the UE is located, in order to determine whether it is appropriate to relax ACLR and SEM.

[0173] c) Assess the feasibility of relaxing ACLR and SEM based on the characteristics of the currently used frequency bands.

[0174] d) Based on the reference signal received power (RSRP), reference signal received quality (RSRQ), or signal-to-noise ratio plus interference ratio (SINR) measurement data reported by the UE, detect the UE's signal status. If it is below a set threshold, generate an indication to relax ACLR and SEM.

[0175] Step 22: Before the base station decides to relax the ACLR and SEM range, it must assess the relative position of the UE channel bandwidth (UE CBW) edge to the base station channel bandwidth (BS CBW) edge (e.g., Figure 3 The offsets 1 and 2 shown are used to determine whether the UE channel bandwidth needs to be increased. If it needs to be increased, the increased bandwidth is the second bandwidth (i.e., the terminal-adjusted channel bandwidth in the above embodiment). The specific steps are as follows:

[0176] a) Calculate the lower edge F of the BS channel bandwidth. BS_low Based on Point A (equivalent to the frequency domain reference point in the above embodiment) and offsetToCarrier, where offsetToCarrier is provided by the corresponding field in ServingCellConfigCommonSIB or sCellConfigCommon depending on the scenario.

[0177] Optionally, if the downlink is a single carrier, offsetToCarrier is given by the ServingCellConfigCommonSIB->DownlinkConfigCommonSIB->FrequencyInfoDL-SIB->scs-SpecificCarrierList field. For the case where the downlink consists of multiple consecutive carriers within a frequency band, offsetToCarrier is the minimum value of the offsetToCarrier values ​​for all carriers. The offsetToCarrier values ​​for all carriers are given by the sCellConfigCommon->ServingCellConfigCommon->DownlinkConfigCommon->frequencyInfoDL->SCS-SpecificCarrier field or the ServingCellConfigCommonSIB->DownlinkConfigCommonSIB->FrequencyInfoDL-SIB->SCS-SpecificCarrier field.

[0178] b) Determine the upper edge F of the BS channel bandwidth. BS_high For the single-carrier case, by F BS_lowThe value is obtained by adding BS CBW, where BS CBW equals the carrierBandwidth in the ServingCellConfigCommonSIB->DownlinkConfigCommonSIB->FrequencyInfoDL-SIB->scs-SpecificCarrierList field. For multi-carrier scenarios, the maximum value of Point A + offsetToCarrier + carrierBandwidth for all carriers is selected, where offsetToCarrier and carrierBandwidth are given by the ServingCellConfigCommonSIB->DownlinkConfigCommonSIB->FrequencyInfoDL-SIB->scs-SpecificCarrierList field or the sCellConfigCommon->ServingCellConfigCommon->DownlinkConfigCommon->frequencyInfoDL->SCS-SpecificCarrier field.

[0179] c) Determine the lower edge FUE_low of the UE channel bandwidth (the first bandwidth, i.e., the current channel bandwidth of the terminal in the above embodiment), which is obtained by adding Point A and offsetToCarrier. offsetToCarrier is given by the ServingCellConfig->downlinkChannelBW-PerSCS-List->SCS-SpecificCarrier field. If this field is empty, it is given by SCS-SpecificCarrier in DownlinkConfigCommon / DownlinkConfigCommonSIB.

[0180] d) Calculate the upper edge F of the UE channel bandwidth (first bandwidth) UE_high Based on F UE_low Add this to the UE-specific channel bandwidth. The UE-specific channel bandwidth is given by the ServingCellConfig->downlinkChannelBW-PerSCS-List->SCS-SpecificCarrier field.

[0181] e) Compare F BS_low -F UE_low and F BS_high -FUE_high That is, whether offset 1 and offset 2 are both greater than or equal to half of UECBW (first bandwidth).

[0182] Step 23: The base station selects at least one of the following methods to send a command to the UE to relax the ACLR and SEM range (sum value):

[0183] a) Send a command to the UE via RRC signaling to relax the ACLR and SEM ranges (and values), the command content of which may be at least one of the following:

[0184] Indicates whether to relax the range (and value) of ACLR and SEM;

[0185] The size of the second bandwidth;

[0186] ACLR relaxation value;

[0187] SEM relaxation value;

[0188] Relaxation values ​​of ACLR and SEM;

[0189] MPR values ​​of outer and edge RB allocations after relaxation of indicators;

[0190] The offset between the first RB of the first bandwidth and the first RB of the second bandwidth;

[0191] Optionally, an instruction to relax ACLR and SEM ranges (and values) is sent to the UE via RRC signaling, with at least one of the following added to the existing RRC signaling:

[0192] RelaxIndicator: 2 bits, 00 means no relaxation, 01 means relax value, range does not relax, 10 means relax range, value does not relax, 11 means relax ACLR and SEM values ​​and range.

[0193] NewBandwidth: Indicates the size of the second bandwidth, which is twice the size of the first bandwidth, in PRB, MHz, or other frequency domain units. This field needs to be used in conjunction with RelaxIndicator. When RelaxIndicator indicates 10 or 11, if this field is not empty, the UE uses the second bandwidth to apply ACLR and SEM indicators. If this field is empty, the UE defaults to using the BS channel bandwidth to apply ACLR and SEM indicators.

[0194] ACLR-RelaxValue: Indicates the ACLR relaxation value in dB. This field needs to be used in conjunction with RelaxIndicator and is valid when RelaxIndicator indicates 01 or 11.

[0195] SEM-RelaxValue: Indicates the SEM relaxation value in dB. This field needs to be used in conjunction with RelaxIndicator and is valid when RelaxIndicator indicates 01 or 11.

[0196] OffsetIndicator: Indicates the offset between the first RB of the first bandwidth and the first RB of the second bandwidth.

[0197] b) Through the MAC CE mechanism, fields can be added to existing control units or new MAC CEs can be created to send at least one of the following:

[0198] Indicates whether to relax the range (and value) of ACLR and SEM; the size of the second bandwidth; the relaxation value of ACLR; the relaxation value of SEM; the relaxation values ​​of ACLR and SEM; the MPR values ​​of outer and edge RB allocations after relaxation indicators; the offset between the first RB of the first bandwidth and the first RB of the second bandwidth.

[0199] c) Using the DCI mechanism, similarly add fields to existing control information or create a new DCI, and send at least one of the following:

[0200] Indicates whether to relax the range (and value) of ACLR and SEM; the size of the second bandwidth; the relaxation value of ACLR; the relaxation value of SEM; the relaxation values ​​of ACLR and SEM; the MPR values ​​of outer and edge RB allocations after relaxation indicators; the offset between the first RB of the first bandwidth and the first RB of the second bandwidth.

[0201] Step 24: After extending the UE CBW, a portion of the original outer RB allocation within the first bandwidth is converted to inner RB allocation and incorporated into a more optimized power control scheme. The new inner RB allocation of the first bandwidth (equivalent to the adjusted internal resource block allocation in the above embodiment) is determined based on the second bandwidth. The new inner RB allocation of the first bandwidth is the intersection of the RB allocation of the first bandwidth and the inner RB allocation of the second bandwidth. The inner RB allocation of the second bandwidth must meet the following conditions:

[0202] RB Start,Low The calculation formula is: RB Start,Low =max(1,floor(L) CRB / 2)) ensures that the starting position of resource block allocation is within a reasonable range, where max() represents taking the maximum value of all parameters, floor(x) represents the largest integer less than or equal to x, and L CRB The size of the resource blocks allocated to the terminal.

[0203] RB Start,High The calculation formula is: RB Start,High =N RB,extended –RB Start,Low –L CRB , where N RB,extended Configure the maximum transmission bandwidth for the second bandwidth.

[0204] The starting position of the internal resource block allocation for the second bandwidth is RB. Start RB must be satisfied simultaneously. Start,Low ≤RB Start ≤RB Start,High And L CRB ≤ceil(N RB,extended / 2).

[0205] The new inner RB allocation for the first bandwidth also needs to satisfy: RB shift ≤RB Start ≤N RB +RB shift Among them, RB shift It is the offset between the first RB of the first bandwidth and the first RB of the second bandwidth, N. RB It is the maximum transmission bandwidth configuration of the first bandwidth.

[0206] Finally, as Figure 4 As shown, the new inner RB allocation should be located below the hypotenuse of the right triangle formed by the RB allocations of the first bandwidth, expressed by the formula: RB Start ≤N RB +RB shift -L CRB .

[0207] It can be deduced that: RB Start ≤N RB +RB shift -L CRB ;

[0208] Therefore, the new inner RB allocation for the first bandwidth can be defined as: RB Start,Low =max(1,floor(L) CRB / 2));

[0209] RB Start,High =NRB,extended –RB Start,Low –L CRB .

[0210] The RB allocation at this time is the inner RB allocation of the first bandwidth when the following conditions are met:

[0211] RB Start,Low ≤RB Start ≤RB Start,High and,

[0212] RB shift ≤RB Start ≤N RB +RB shift and,

[0213] RB Start ≤N RB +RB shift -L CRB and,

[0214] L CRB ≤ceil(N RB,extended / 2).

[0215] Optionally, under specific communication conditions or scenarios, the terminal (UE) autonomously assesses whether it should perform adjacent channel leakage ratio (ACLR) and / or spectrum leakage template (SEM) relaxation operations to optimize uplink maximum power back-off (MPR). If a relaxation is decided, the UE will report the relaxation requirement and its specific parameters to the network through Radio Resource Control (RRC) signaling, MAC Control Element (MAC CE), Uplink Control Information (UCI), or capability reporting mechanisms, so that the network scheduling can perform more efficient resource allocation and power control, including:

[0216] Step 31: The UE makes a decision on ACLR and / or SEM relaxation based on at least one of the following strategies:

[0217] a) Consult Public Land Mobile Network (PLMN) information to confirm whether the policies of your country and operator support the relaxation of ACLR and SEM.

[0218] b) Combine PLMN and Tracking Area Code (TAC) to analyze the environmental conditions of the tracking area and determine whether it is appropriate to implement ACLR and SEM relaxation.

[0219] c) Assess the characteristics of the currently used frequency bands and determine the feasibility of relaxing ACLR and SEM.

[0220] d) Analyze the reported Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), or Signal-to-Noise Ratio Plus Interference Ratio (SINR) measurement results. If the signal quality is detected to be below a preset threshold, trigger ACLR and SEM relaxation commands. The measurement results are based on L1 or L3 layer data.

[0221] Step 32: The UE shall report its ACLR and SEM relaxation decisions to the base station by at least one of the following methods:

[0222] a) Using Radio Resource Control (RRC) signaling, the indication includes at least one of the following:

[0223] Whether ACLR and / or SEM are relaxed; the relaxation value of ACLR; the relaxation value of SEM; the relaxation values ​​of ACLR and SEM; the MPR values ​​of outer and edge RB allocations after relaxing ACLR and / or SEM.

[0224] Add at least one of the following fields to the RRC signaling:

[0225] RelaxIndicator: 2 bits, 00 indicates no relaxation, 01 indicates ACLR relaxation, 10 indicates SEM relaxation, 11 indicates both ACLR and SEM relaxation.

[0226] ACLR-RelaxValue: Indicates the ACLR relaxation value, in dB;

[0227] SEM-RelaxValue: Indicates the SEM relaxation value, in dB;

[0228] MPR-OuterValue: Indicates the MPR value of outer RB allocations after ACLR and / or SEM relaxation, in dB;

[0229] MPR-EdgeValue: Indicates the MPR value of edge RB allocations after ACLR and / or SEM relaxation, in dB.

[0230] b) Instructions via the Media Access Control Controller (MAC CE), specifically in two ways: either by adding fields to an existing MAC CE, or by adding a new MAC CE. The instructions can be at least one of the following:

[0231] Whether ACLR and / or SEM are relaxed; the relaxation value of ACLR; the relaxation value of SEM; the relaxation values ​​of ACLR and SEM; the MPR values ​​of outer and edge RB allocations after relaxing ACLR and / or SEM.

[0232] c) Using downlink control information (DCI) to indicate, specifically in two ways: one is to add some fields to the existing DCI, and the other is to add a new DCI. The indication content can be at least one of the following:

[0233] Whether ACLR and / or SEM are relaxed; the relaxation value of ACLR; the relaxation value of SEM; the relaxation values ​​of ACLR and SEM; the MPR values ​​of outer and edge RB allocations after relaxing ACLR and / or SEM.

[0234] d) Reporting ACLR relaxation and / or SEM via UE capability. Add one or more UE capabilities and report at least one of the following to the network:

[0235] Whether ACLR and / or SEM are relaxed; the relaxation value of ACLR; the relaxation value of SEM; the relaxation values ​​of ACLR and SEM; the MPR values ​​of outer and edge RB allocations after relaxing ACLR and / or SEM.

[0236] Through this mechanism, the UE can proactively report its ACLR and SEM relaxation intentions and parameters to the network, providing crucial information to ensure that uplink resource allocation and power control policies meet both the UE's performance requirements and comply with spectrum management regulations, thereby improving the overall network's spectrum efficiency and communication quality. This process not only enhances the network's adaptability but also helps improve UE coverage and capacity in edge areas, optimizes user experience, and demonstrates the flexibility and efficiency of 5G networks in spectrum resource management and power control.

[0237] Optionally, for certain specific scenarios, the UE determines whether to relax the application scope (and value) of ACLR and SEM. If relaxed, it needs to report to the network for network scheduling purposes, including:

[0238] Step 41: The terminal decides whether to perform ACLR and SEM relaxation based on at least one of the following strategies:

[0239] a) Based on Public Land Mobile Base Station (PLMN) information, confirm whether the geographical location of the UE and the regulations of its operator allow for the relaxation of ACLR and SEM.

[0240] b) Combine PLMN and Tracking Area Code (TAC) to analyze the environmental factors in the tracking area where the UE is located, in order to determine whether it is appropriate to relax ACLR and SEM.

[0241] c) Assess the feasibility of relaxing ACLR and SEM based on the characteristics of the currently used frequency bands.

[0242] d) Based on the reference signal received power (RSRP), reference signal received quality (RSRQ), or signal-to-noise ratio plus interference ratio (SINR) measurement data reported by the UE, detect the UE's signal status. If it is below a set threshold, generate an indication to relax ACLR and SEM.

[0243] Step 42: Before the terminal decides to relax the application scope of ACLR and SEM, it must evaluate the relative position of the edge of the UE channel bandwidth (UE CBW) and the edge of the base station channel bandwidth (BS CBW) (e.g., Figure 3 The offsets 1 and 2 shown are used to determine whether the UE channel bandwidth needs to be increased. If it needs to be increased, the increased bandwidth is the second bandwidth (i.e., the terminal-adjusted channel bandwidth in the above embodiment). The specific steps are as follows:

[0244] a) Calculate the lower edge F of the BS channel bandwidth. BS_low Based on Point A (equivalent to the frequency domain reference point in the above embodiment) and offsetToCarrier, where offsetToCarrier is provided by the corresponding field in ServingCellConfigCommonSIB or sCellConfigCommon depending on the scenario.

[0245] Optionally, if the downlink is a single carrier, offsetToCarrier is given by the ServingCellConfigCommonSIB->DownlinkConfigCommonSIB->FrequencyInfoDL-SIB->scs-SpecificCarrierList field. For the case where the downlink consists of multiple consecutive carriers within a frequency band, offsetToCarrier is the minimum value of the offsetToCarrier values ​​for all carriers. The offsetToCarrier values ​​for all carriers are given by the sCellConfigCommon->ServingCellConfigCommon->DownlinkConfigCommon->frequencyInfoDL->SCS-SpecificCarrier field or the ServingCellConfigCommonSIB->DownlinkConfigCommonSIB->FrequencyInfoDL-SIB->SCS-SpecificCarrier field.

[0246] b) Determine the upper edge F of the BS channel bandwidth. BS_high For the single-carrier case, by F BS_lowThe value is obtained by adding BS CBW, where BS CBW equals the carrierBandwidth in the ServingCellConfigCommonSIB->DownlinkConfigCommonSIB->FrequencyInfoDL-SIB->scs-SpecificCarrierList field. For multi-carrier scenarios, the maximum value of Point A + offsetToCarrier + carrierBandwidth for all carriers is selected, where offsetToCarrier and carrierBandwidth are given by the ServingCellConfigCommonSIB->DownlinkConfigCommonSIB->FrequencyInfoDL-SIB->scs-SpecificCarrierList field or the sCellConfigCommon->ServingCellConfigCommon->DownlinkConfigCommon->frequencyInfoDL->SCS-SpecificCarrier field.

[0247] c) Determine the lower edge FUE_low of the UE channel bandwidth (the first bandwidth, i.e., the current channel bandwidth of the terminal in the above embodiment), which is obtained by adding Point A and offsetToCarrier. offsetToCarrier is given by the ServingCellConfig->downlinkChannelBW-PerSCS-List->SCS-SpecificCarrier field. If this field is empty, it is given by SCS-SpecificCarrier in DownlinkConfigCommon / DownlinkConfigCommonSIB.

[0248] d) Calculate the upper edge F of the UE channel bandwidth (first bandwidth) UE_high Based on F UE_low Add this to the UE-specific channel bandwidth. The UE-specific channel bandwidth is given by the ServingCellConfig->downlinkChannelBW-PerSCS-List->SCS-SpecificCarrier field.

[0249] e) Compare F BS_low -F UE_low and F BS_high -FUE_high That is, whether offset 1 and offset 2 are both greater than or equal to half of UECBW (first bandwidth).

[0250] Step 33: The UE shall report its ACLR and SEM relaxation decisions to the base station by at least one of the following methods:

[0251] a) Using Radio Resource Control (RRC) signaling, the indication includes at least one of the following:

[0252] Whether ACLR and / or SEM are relaxed; the relaxation value of ACLR; the relaxation value of SEM; the relaxation values ​​of ACLR and SEM; the MPR values ​​of outer and edge RB allocations after relaxing ACLR and / or SEM.

[0253] Add at least one of the following fields to the RRC signaling:

[0254] RelaxIndicator: 2 bits, 00 indicates no relaxation, 01 indicates ACLR relaxation, 10 indicates SEM relaxation, 11 indicates both ACLR and SEM relaxation.

[0255] ACLR-RelaxValue: Indicates the ACLR relaxation value, in dB;

[0256] SEM-RelaxValue: Indicates the SEM relaxation value, in dB;

[0257] MPR-OuterValue: Indicates the MPR value of outer RB allocations after ACLR and / or SEM relaxation, in dB;

[0258] MPR-EdgeValue: Indicates the MPR value of edge RB allocations after ACLR and / or SEM relaxation, in dB.

[0259] b) Instructions via the Media Access Control Controller (MAC CE), specifically in two ways: either by adding fields to an existing MAC CE, or by adding a new MAC CE. The instructions can be at least one of the following:

[0260] Whether ACLR and / or SEM are relaxed; the relaxation value of ACLR; the relaxation value of SEM; the relaxation values ​​of ACLR and SEM; the MPR values ​​of outer and edge RB allocations after relaxing ACLR and / or SEM.

[0261] c) Using downlink control information (DCI) to indicate, specifically in two ways: one is to add some fields to the existing DCI, and the other is to add a new DCI. The indication content can be at least one of the following:

[0262] Whether ACLR and / or SEM are relaxed; the relaxation value of ACLR; the relaxation value of SEM; the relaxation values ​​of ACLR and SEM; the MPR values ​​of outer and edge RB allocations after relaxing ACLR and / or SEM.

[0263] d) Reporting ACLR relaxation and / or SEM via UE capability. Add one or more UE capabilities and report at least one of the following to the network:

[0264] Whether ACLR and / or SEM are relaxed; the relaxation value of ACLR; the relaxation value of SEM; the relaxation values ​​of ACLR and SEM; the MPR values ​​of outer and edge RB allocations after relaxing ACLR and / or SEM.

[0265] Step 44: After extending the UE CBW, a portion of the original outer RB allocation within the first bandwidth is converted to inner RB allocation and incorporated into a more optimized power control scheme. The new inner RB allocation of the first bandwidth (equivalent to the adjusted internal resource block allocation in the above embodiment) is determined based on the second bandwidth. The new inner RB allocation of the first bandwidth is the intersection of the RB allocation of the first bandwidth and the inner RB allocation of the second bandwidth. The inner RB allocation of the second bandwidth must meet the following conditions:

[0266] R BStart,Low The calculation formula is: R BStart,Low =max(1,floor(L) CRB / 2)) ensures that the starting position of resource block allocation is within a reasonable range, where max() represents taking the maximum value of all parameters, floor(x) represents the largest integer less than or equal to x, and L CRB The size of the resource blocks allocated to the terminal.

[0267] R BStart,High The calculation formula is: RB Start,High =N RB,extended –RB Start,Low –L CRB , where N RB,extended Configure the maximum transmission bandwidth for the second bandwidth.

[0268] The starting position of the internal resource block allocation for the second bandwidth is RB. Start RB must be satisfied simultaneously. Start,Low ≤RB Start ≤RB Start,High And LCRB≤ceil(N) RB,extended / 2).

[0269] The new inner RB allocation for the first bandwidth also needs to satisfy: RB shift ≤RB Start ≤N RB +RB shift Among them, RB shift It is the offset between the first RB of the first bandwidth and the first RB of the second bandwidth, N. RB It is the maximum transmission bandwidth configuration of the first bandwidth.

[0270] Finally, as Figure 4 As shown, the new inner RB allocation should be located below the hypotenuse of the right triangle formed by the RB allocations of the first bandwidth, expressed by the formula: RB Start ≤N RB +RB shift -L CRB .

[0271] It can be deduced that: RB Start ≤N RB +RB shift -L CRB ;

[0272] Therefore, the new inner RB allocation for the first bandwidth can be defined as: RB Start,Low =max(1,floor(L) CRB / 2));

[0273] RB Start,High =N RB,extended –RB Start,Low –L CRB .

[0274] The RB allocation at this time is the inner RB allocation of the first bandwidth when the following conditions are met:

[0275] RB Start,Low ≤RB Start ≤RB Start,High and,

[0276] RB shift ≤RB Start ≤NRB +RB shift and,

[0277] RB Start ≤N RB +RB shift -L CRB and,

[0278] L CRB ≤ceil(N RB,extended / 2).

[0279] Optionally, for certain specific scenarios, the UE determines whether to relax ACLR and SEM. If relaxation is required, it sends a request to the network to relax ACLR and SEM. The network then responds to the UE based on scheduling conditions to determine whether relaxation is possible. Specifically, first, the UE determines whether to relax ACLR and / or SEM according to the above-described method. If relaxation is required, it sends a request to the network. Then, the network instructs the UE, based on scheduling conditions, to reduce MPR by relaxing ACLR and / or SEM values ​​or by relaxing the application scope (and value) of ACLR and SEM. If the instruction is to relax ACLR and / or SEM values, the instruction method and content can refer to the method described above for base stations instructing terminals to relax ACLR and / or SEM values. If the instruction is to relax the application scope (and value) of ACLR and SEM, the instruction method, content, and the method for determining the content can refer to the method described above for base stations instructing terminals to relax the application scope (and value) of ACLR and / or SEM.

This computer software product is stored in a storage medium (such as ROM / RAM, magnetic disk, optical disk) and includes several instructions to cause a terminal device (which may be a mobile phone, computer, server, or network device, etc.) to execute the methods described in the various embodiments of this application.

[0281] This embodiment also provides a parameter information relaxation device, which is used to implement the above embodiments and preferred embodiments; details already described will not be repeated.

When downlink transmission is performed using a single carrier, the upper edge frequency point of the current channel bandwidth of the base station is determined based on the lower edge frequency point of the base station and the current channel bandwidth of the base station. When the base station performs downlink transmission using multiple consecutive carriers within a frequency band, the frequency domain reference point of the base station, the offset of each carrier relative to the frequency domain reference point of the base station, and the bandwidth of each carrier are determined.
