Description

Technical Field

[0001] This invention relates to the field of communication technology, and in particular to an MCS determination method, apparatus, electronic device, and storage medium. Background Technology

[0002] To address the high energy consumption associated with large bandwidth, NR (New Radio) systems introduced the concept of BWP (Bandwidth Part), enabling base stations to dynamically select appropriate bandwidth based on UE (User Equipment) requirements to achieve energy savings. When switching to a target BWP, the MCS (Modulation and Coding Scheme) level needs to be evaluated, and the scheduling strategy is determined based on the MCS. However, the reference measurement structure of the target BWP cannot be obtained before the handover, making it impossible to accurately calculate the initial MCS of the target BWP.

[0003] Currently, there are two methods for determining the initial MCS of a target BWP, depending on the BWP switching direction: When switching from a large BWP to a small BWP, the initial bandwidth MCS of the small BWP inherits the last updated cumulative bandwidth MCS maintained on the large BWP; when switching from a small BWP to a large BWP, for the bandwidth of the large BWP, the initial MCS directly inherits the last updated cumulative bandwidth MCS maintained on the small BWP, and for the subbands of the large BWP, the MCS of the boundary PRB (Physical Resource Block) of the small BWP is extended to the remaining PRBs of the large BWP.

[0004] However, this method requires extending the MCS on the source BWP boundary PRB to the target BWP in order to determine the initial MCS of the target BWP. Therefore, it is only applicable to scenarios where the BWPs have intersections in the frequency domain, and its applicability is insufficient.

[0005] Furthermore, if the interference noise power at different frequency points differs significantly, the cumulative broadband MCS maintained on the source BWP is not suitable for the target BWP. Alternatively, if the interference noise power between subbands differs significantly, the measured value of the source BWP boundary PRB is not suitable for extension to the target BWP. Therefore, the initial MCS of the target BWP determined by the above method may not be accurate enough.

[0006] In practical application scenarios, the initial MCS will affect the base station scheduling strategy. If the initial MCS is not accurately evaluated, adopting an overly aggressive base station scheduling strategy may lead to UE re-establishment or disconnection, while adopting an overly conservative base station scheduling strategy may lead to a sudden drop in service. Therefore, the inability to accurately evaluate the initial MCS will ultimately affect the network KPI (Key Performance Indicators) and UE service perception. Summary of the Invention

[0007] The purpose of this invention is to provide an MCS determination method, apparatus, electronic device, and storage medium to improve the applicability and accuracy of the MCS determination method when determining the initial MCS for a target BWP after handover, and ultimately maintain network KPIs and UE service awareness in practical application scenarios.

This invention obtains the interference noise power on the target BWP based on the interference noise power set on the system bandwidth, which does not depend on the frequency domain position relationship between the source BWP and the target BWP, thus having wide applicability. Furthermore, since the bandwidth frequency domain range of the target BWP is within the frequency domain range of the system bandwidth, it is not necessary to accumulate or expand the MCS on the source BWP when determining the initial MCS on the target BWP, resulting in higher accuracy of the initial MCS. Therefore, in practical application scenarios, this method can maintain network KPIs and UE service awareness.

[0068] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art based on this application are within the scope of protection of the present invention.

[0069] To provide a clearer explanation of the technical solutions in the embodiments of the present invention, the following will first combine... Figure 1 and Figure 2 The introduction of necessary related technologies within the technical field of the embodiments of the present invention does not constitute a limitation on the technical solutions provided by the embodiments of the present invention.

[0070] Figure 1 This is an example diagram of a network architecture provided in an embodiment of the present invention, which includes a base station 110 and a UE 120.

[0071] Base station 110, also known as public mobile communication base station, is used to provide UE120 with an interface for accessing the network and to enable communication between multiple UE120s.

[0072] In the communication process, the entire area covered by a base station may be divided into one or more different areas, that is, multiple cells, each of which constitutes the basic unit for providing communication services to users.

[0073] UE120 may include various user equipment and terminals with wireless communication capabilities, such as mobile phones and mobile computers.

[0074] The base station 110 and UE 120 can communicate via air interface technology. For example, in a 5G scenario, the base station 110 and UE 120 can communicate via NR.

[0075] Figure 2 This is an example diagram of BWP dynamic switching provided in an embodiment of the present invention. The following is in conjunction with... Figure 2Let me explain BWP. BWP is a concept introduced with the development of 5G technology. Because 5G has a larger carrier bandwidth, NR sets up BWP to achieve flexible bandwidth configuration in order to reduce UE power consumption. In other words, BWP is equivalent to dividing the total bandwidth of the cell into BWPs with different bandwidths at different times, configuring one or more of these BWPs for the UE, enabling the UE to dynamically switch between different BWPs to adapt to different service requirements.

[0076] refer to Figure 2 Example of dynamic BWP switching in the document. Figure 2 The horizontal axis represents time, and the vertical axis represents frequency. The span of the frequency band on the vertical axis, that is, the difference between the highest and lowest frequencies, is called bandwidth, which is used to characterize the transmission capability of the frequency band. In the following text, the term "size" of the frequency band may also be used to describe the same meaning as the bandwidth size.

[0077] It can be seen Figure 2 The diagram illustrates the bandwidth allocation for two types of components, BWP1 and BWP2, where BWP1 has a smaller bandwidth and BWP2 has a larger bandwidth. For example, if a UE has low transmission capacity requirements, only the BWP with the smaller bandwidth can be configured for that UE, thus saving resources.

[0078] In practical applications, a UE can be configured with one or more BWPs, but only one can be active at a time. (Reference) Figure 2 It can be seen that BWP1 is activated first, and then... Figure 2 After the BWP switching point shown, BWP2 is activated. After BWP2 is activated for a period of time, BWP1 is activated again.

[0079] from Figure 2 As can be seen, after the activated BWP is switched from BWP1 to BWP2, the bandwidth used for communication between the UE and the base station changes from a small bandwidth to a large bandwidth. The BWP switch will affect... Figure 1 The network architecture shown in the diagram has an impact, therefore, during the process... Figure 2 Before the dynamic handover from BWP1 to BWP2, it is necessary to predetermine the initial scheduling strategy of the base station that matches BWP2, especially the initial MCS.

[0080] Before switching BWPs, the reference signal measurement results on the target BWP are unavailable. If BWP2 inherits the latest updated cumulative MCS maintained on BWP1, there are issues with insufficient applicability and poor accuracy. Furthermore, applying a scheduling strategy based on an inaccurate initial MCS to... Figure 1 The network architecture shown may further impact network KPIs and UE service perception.

[0081] To address the above problems, embodiments of the present invention provide an MCS determination method. Figure 3 This is a flowchart illustrating the MCS determination method provided in an embodiment of the present invention, as shown below. Figure 3 As shown, the method includes the following steps:

[0082] Step S110: Obtain the set of interference noise power on the system bandwidth; when a partial bandwidth BWP switching signal is received, determine the interference noise power of the target BWP based on the frequency domain position of the target BWP on the system bandwidth and the set of interference noise power.

[0083] System bandwidth, or total bandwidth, refers to the total bandwidth of the cell.

[0084] The interference noise power set refers to the interference noise power at multiple different frequency domain locations across the entire bandwidth. In one embodiment of the present invention, the interference noise power set is calculated by measuring signal values.

[0085] In one embodiment of the present invention, the calculation of the interference noise power set is performed periodically. The present invention does not limit the size of the period; in one embodiment, the period is set to the order of seconds.

[0086] In one embodiment of the present invention, the determination of the interference noise power of the target BWP is event-triggered. In other words, if no BWP switching occurs, even if the calculation of the interference noise power set is performed periodically, there is no step to further determine the interference noise power of the target BWP based on this. Furthermore, when the calculation of the interference noise power set is performed periodically, the interference noise power on the target BWP is also calculated at the same period.

[0087] In this embodiment of the invention, the interference noise power on the target BWP is determined based on the frequency domain position of the target BWP in the system bandwidth and the set of interference noise power. Figure 2 The examples show that the frequency domain range of each BWP is within the frequency domain range of the system bandwidth, and the position of the BWP in the system bandwidth can be obtained through the BWP configuration information. Therefore, it can be understood that the embodiments of the present invention combine frequency domain position to obtain the interference noise power on the target BWP based on the interference noise power set on the system bandwidth, without needing to accumulate or expand the MCS on the source BWP, and the applicability is not affected by the frequency domain position relationship between different BWPs.

[0088] Step S120: Determine the signal-to-noise ratio of the target BWP based on the interference noise power of the target BWP and the uplink signal received power of the target BWP.

[0089] Specifically, the signal-to-noise ratio (SNR) is calculated according to the following formula:

[0090] Signal-to-noise ratio = Received signal power / Interference noise power

[0091] The interference noise power refers to the interference noise power of the target BWP determined in step S110. In this embodiment of the invention, the signal reception power specifically refers to the uplink signal reception power of the target BWP, that is, the signal reception power on the network side when the UE transmits signals to the base station through the uplink channel. The method for determining the uplink signal reception power of the target BWP in this embodiment of the invention will be described in detail later.

[0092] Step S130: Determine the uplink MCS of the target BWP based on the signal-to-noise ratio.

[0093] The uplink MCS refers to the MCS matched by the uplink channel from which the UE transmits signals to the base station. In contrast, the MCS matched by the downlink channel from which the base station transmits signals to the UE is called the downlink MCS.

[0094] Specifically, in this embodiment of the invention, the method of steps S110-S130 is applied to the scenario of dynamic BWP switching, and is used to determine the initial MCS on the target BWP before switching to the target BWP. Figure 2 For example, suppose a UE is pre-configured with two partial bandwidths, BWP1 and BWP2. BWP1 is activated first, and after a period of time, it switches to BWP2. In this case, BWP1 is called the source BWP, and BWP2 is called the target BWP. The method provided in this embodiment of the invention is used to pre-determine the initial MCS of BWP2 after switching to BWP2 before BWP2 is activated.

[0095] The MCS determination method provided in this invention first obtains the interference noise power on the target BWP based on its frequency domain position in the system bandwidth and the set of interference noise power in the system bandwidth. Since the frequency domain range of the target BWP's bandwidth is within the frequency domain range of the system bandwidth, the interference noise power on the target BWP can be obtained without approximate accumulation or extended calculations, resulting in high accuracy. Furthermore, calculations based on the set of interference noise power in the system bandwidth are not affected by the frequency domain position relationship between different BWPs, thus exhibiting high applicability. Consequently, when determining the signal-to-noise ratio based on the interference noise power and uplink signal received power, and further determining the uplink MCS, the determined MCS also has high accuracy, and the method has wide applicability. When the determined uplink MCS is actually applied to determine the base station scheduling strategy, a more accurate scheduling strategy can be obtained, which can maintain network KPIs and UE service awareness.

[0096] In another possible embodiment of the invention, in Figure 3 Based on the MCS determination method shown, a further improvement is proposed. The improvement is to provide a method to determine the interference noise power of the target BWP based on its frequency domain location in the system bandwidth and the interference noise power set, which can be applied after obtaining the interference noise power set in the system bandwidth. Figure 4 This is a flowchart illustrating the method for determining the interference noise power of a target BWP provided in an embodiment of the present invention, in conjunction with... Figure 4 The method specifically includes the following steps:

[0097] Step S111: Based on the frequency domain position of the target BWP in the system bandwidth, determine the correspondence between the CRB of the system bandwidth and the PRB of the target BWP.

[0098] To make the explanation of the method for determining the interference noise power of a target BWP clearer, the concept of RB (Resource Block) will be introduced first.

[0099] RB is a unit of bandwidth occupied by service resources. An RB includes multiple consecutive subcarriers in the frequency domain. For example, in a 5G system, an RB refers to 12 consecutive subcarriers.

[0100] CRB (Carrier Resource Block) and PRB are used to index and indicate RB. Figure 5 This is an example diagram of a resource block provided in an embodiment of the present invention. The following is in conjunction with... Figure 5 Explanation of PRB and CRB.

[0101] Specifically, a common reference point, Point A, is defined within the system bandwidth, and its position in the frequency domain is fixed. CRBs are numbered sequentially from 0, starting from Point A, within the system bandwidth. When a BWP is configured, the PRB assigns sequential numbering to all RBs within a given BWP, starting from 0.

[0102] refer to Figure 5 It can be seen that the CRB is numbered starting from Point A in terms of system bandwidth. Figure 5 The image shows three BWPs, BWP#1, BWP#2, and BWP#3. It can be seen that each BWP is numbered starting from 0 by the PRB. For example, Figure 5 Within BWP#1, PRB is numbered from 0 to N1.

[0103] Therefore, it can be simply understood that the PRB is the index of the RB in the BWP, and the CRB is the index of the RB in the system bandwidth. Thus, the correspondence between the CRB of the system bandwidth and the PRB of the target BWP can also be understood as the positional relationship between the system bandwidth and the resource blocks in the target BWP.

[0104] In step S111, the interference noise power set is the interference noise power of each CRB in the system bandwidth.

[0105] Step S112: Determine the interference noise power of each PRB on the target BWP based on the interference noise power and corresponding relationship of each CRB.

[0106] After obtaining the interference noise power of each CRB, steps S111 and S112 obtain the interference noise power at the overlapping RB positions one by one according to the principle of RB alignment.

[0107] Figure 6 This is an example diagram of the RB grid provided in the embodiment of the present invention. The following is in conjunction with... Figure 6 The principles of RB alignment and the method for determining the interference noise power at the overlapping position are briefly explained.

[0108] Specifically, the metric of RB in the frequency domain can vary depending on the different subcarrier configurations, but the starting boundaries of RBs with different metrics are always aligned.

[0109] Figure 6 The diagram illustrates RB grids under three different subcarrier configurations with subcarrier spacings of Δf, 2Δf, and 4Δf. Each row represents an RB grid under one subcarrier configuration. It can be seen that the RB boundaries are always aligned; therefore, the overlapping RBs between different configurations are always one-to-one or one-to-many, meaning the correspondence is explicit. For example, RBs numbered 0 and 1 in the subcarrier with a subcarrier spacing of Δf correspond to RB number 0 in the subcarrier with a subcarrier spacing of 2Δf.

[0110] When a BWP configuration exists, different BWPs may have different subcarrier configurations. Based on a similar principle, there may also be a one-to-one or one-to-many relationship between the CRB on the system bandwidth and the PRB on the target BWP. According to this correspondence, the interference noise power of the CRB can be used as the interference noise power of the PRB at the overlapping position.

[0111] Specifically, there are three correspondences between CRB and PRB:

[0112] The target BWP's PRB and the system bandwidth's CRB are in one-to-one correspondence;

[0113] One PRB for the target BWP corresponds to multiple CRBs for the system bandwidth;

[0114] The target BWP has multiple PRBs and a system bandwidth corresponding to one CRB.

[0115] In one embodiment of the present invention, the interference noise power of each PRB on the target BWP is determined by the following method:

[0116] When the PRB of the target BWP and the CRB of the system bandwidth correspond one-to-one, the interference noise power of the CRB is determined as the interference noise power of the PRB.

[0117] When a PRB of a target BWP corresponds to multiple CRBs of the system bandwidth, the linear average of the interference noise power of the multiple CRBs is determined as the interference noise power of a PRB.

[0118] When multiple PRBs of the target BWP correspond to one CRB of the system bandwidth, the interference noise power of one CRB is determined as the interference noise power of each of the multiple PRBs.

[0119] For example, assuming the position of PRB 0 on the target BWP corresponds to the position of CRB n on the system bandwidth, and the position of PRB1 corresponds to the position of CRB n+1 (i.e., a one-to-one correspondence between the target BWP's PRBs and the system bandwidth's CRBs as described above), the interference noise power of CRB n is determined as the interference noise power of PRB 0, and the interference noise power of CRB n+1 is determined as the interference noise power of PRB 1. Assuming the position of PRB 0 on the target BWP corresponds to the positions of CRB n and CRB n+1 on the system bandwidth (i.e., a correspondence between one PRB of the target BWP and multiple CRBs on the system bandwidth as described above), the linear average of the interference noise of CRB n and CRB n+1 is determined as the interference noise power of PRB 0. Assuming the positions of PRB 0 and PRB 1 on the target BWP correspond to the positions of CRB n on the system bandwidth (i.e., a correspondence between one PRB of the target BWP and multiple CRBs on the system bandwidth as described above), then the interference noise power of both PRB 0 and PRB 1 is the interference noise power of CRB n.

[0120] Step S113: Based on the interference noise power of each PRB, obtain the interference noise power of the broadband and the interference noise power of each sub-band.

[0121] The bandwidth of the target BWP refers to the size of the configured BWP, while the subband is a series of consecutive PRBs on the target BWP. The bandwidth and subband sizes can be obtained through the target BWP configuration.

[0122] In one embodiment of the present invention, the interference noise power of the broadband and subband is obtained through the following steps:

[0123] Obtain the bandwidth and size of each subband on the target BWP;

[0124] Based on the bandwidth and the size of each subband, the interference noise power of multiple PRBs corresponding to the bandwidth and each subband is linearly averaged to obtain the interference noise power of the bandwidth and the interference noise power of each subband.

[0125] In one embodiment of the present invention, the interference noise power of the broadband is synchronously updated to Noise_Interfere_Power_WideBand, and the interference noise power of the i-th sub-band is updated to Noise_Interfere_Power_Sub-band_i. Here, i is only used to distinguish multiple sub-bands and serves as an example, not as a limitation. The method for confirming the interference noise power of each sub-band is the same. The parameters Noise_Interfere_Power_WideBand and Noise_Interfere_Power_Sub-band_i can be used to determine the MCS, and the specific operation will be described later.

[0126] In determining the interference noise power of each PRB on the target BWP, this embodiment of the invention utilizes the alignment principle of RBs. Based on the correspondence between the PRBs on the target BWP and the CRBs on the system bandwidth, the interference noise power of the CRB is confirmed as the interference noise power of the corresponding PRB, resulting in high accuracy. When determining the bandwidth and subband interference noise power of the target BWP, a linear average is performed on the interference noise power of each PRB corresponding to the bandwidth and subband of the target BWP, yielding highly accurate results.

[0127] Another possible embodiment of the invention is in Figure 3 Based on the MCS determination method shown, a further improvement is proposed. The improvement is to provide an uplink MCS determination method, which is applied after step S110. Figure 7a and Figure 7b This is a flowchart illustrating the uplink MCS determination method provided in this embodiment of the invention. This method determines the uplink MCS for both the bandwidth and subband of the target BWP. The following explanation uses the determination of the uplink MCS for the bandwidth as an example:

[0128] First, based on the interference noise power and uplink signal received power of the target BWP's bandwidth, the signal-to-noise ratio (SNR) of the target BWP's bandwidth is determined. Then, the uplink MCS of the bandwidth is determined based on the SNR. This specifically includes the following steps:

[0129] Step S121a: Calculate the transmit power of the broadband based on its size.

[0130] Here, transmit power refers to the broadband uplink transmit power. In one embodiment of the present invention, the transmit power is calculated with reference to the formula in TS38.213.

[0131] Step S122a: Calculate the uplink signal receiving power of the broadband based on the corresponding transmit power and link loss.

[0132] Referring to the description in step S120, the uplink signal received power of the broadband, or the useful signal received power over the broadband, is specifically used to determine the signal-to-noise ratio (SNR) of the target BWP, and further determine the uplink MCS based on the SNR. Therefore, the signal received power used to determine the SNR here should be the uplink signal received power on the network side. In practical application scenarios, it is difficult to obtain the uplink signal received power through direct measurement. Therefore, this embodiment of the invention provides a method for estimating the signal received power.

[0133] In one embodiment of the present invention, the uplink signal received power is estimated based on link loss and broadband uplink transmit power, and the specific calculation satisfies the following formula:

[0134] Uplink signal received power = transmit power - link loss

[0135] Specifically, the link loss is predetermined based on the UE transmit power and the network-side receive power. In one embodiment of the present invention, the link loss is calculated on the source BWP side during BWP handover, and the calculation method satisfies the following formula:

[0136] PathLoss=Max_Tx_Power–Power_Headroom–Recive_Power

[0137] Wherein, PathLoss represents the link loss between the UE and the base station, Max_Tx_Power represents the maximum transmit power of the UE, Power_Headroom represents the reported value of the remaining power of the UE, and Receive_Power represents the receive power on the source BWP.

[0138] Step S123a: Determine the signal-to-noise ratio of the target BWP's broadband based on the broadband uplink signal received power and the broadband interference noise power.

[0139] Specifically, the calculation of the signal-to-noise ratio can be referred to the description in step S120 above, and will not be repeated here.

[0140] Step S130a: Determine the uplink MCS of the target BWP based on the signal-to-noise ratio of the target BWP's bandwidth.

[0141] In one embodiment of the present invention, a mapping relationship between signal-to-noise ratio and MCS is established based on product performance to obtain the broadband uplink MCS and update it to MCS_UL_WideBand.

[0142] The method for calculating the uplink MCS of a subband of a target BWP is similar to that for calculating the uplink MCS of a broadband network. Specifically, the signal-to-noise ratio (SNR) of the target BWP's subband is determined based on its interference noise power and uplink signal received power, and then the uplink MCS is determined based on the SNR. The following explanation uses the determination of the uplink MCS of any subband on the target BWP as an example, and includes the following steps:

[0143] Step S121b: Calculate the transmit power of the subband based on its size.

[0144] Step S122b: Calculate the uplink signal receiving power of the sub-band based on the corresponding transmit power and link loss.

[0145] Step S123b: Determine the signal-to-noise ratio of the target BWP's subband based on the uplink signal received power and the interference noise power of the subband.

[0146] Step S130b: Determine the uplink MCS of the subband of the target BWP based on the signal-to-noise ratio of the subband.

[0147] Optionally, the uplink MCS of the i-th subband can be updated to MCS_UL_Sub-band_i.

[0148] Since the calculation of the uplink MCS of the broadband and subband is based on the same principle, the specific details involved can be found in the descriptions in steps S121a-S130a, where the broadband is replaced with the subband.

[0149] In this embodiment of the invention, after obtaining the interference noise power of the broadband and subband on the target BWP, the uplink signal received power of the broadband and subband on the target BWP is first estimated based on link loss and transmit power. The obtained uplink signal received power has high accuracy, thus the signal-to-noise ratio (SNR) obtained when determining the SNR based on the uplink signal received power and interference noise power also has high accuracy. After calculating the SNR of the broadband and subband, a mapping relationship between the SNR and MCS is established to determine the uplink MCS of the broadband and subband, and the obtained uplink MCS also has high accuracy.

[0150] Another possible embodiment of the invention is in Figure 3Based on the MCS determination method shown, a further improvement is proposed, which is that the method also includes a method for determining the downlink MCS. Figure 8a and Figure 8b This is a flowchart illustrating the downlink MCS determination method provided in this embodiment of the invention. The method determines the downlink MCS for both the bandwidth and subband of the target BWP. The determination of the downlink MCS for the bandwidth will be used as an example for explanation below:

[0151] Step S141a: Obtain the interference noise power and downlink MCS of the source BWP.

[0152] In one embodiment of the present invention, when the communication between the base station and the UE adopts the TDD (Time Division Duplexing) standard, the uplink detected interference noise power can be used instead of the downlink power. In the TDD standard, reception and transmission occur at different times on the same frequency channel, therefore the uplink and downlink channels can be considered symmetrical.

[0153] Step S142a: Determine the first change in interference noise power before and after BWP handover based on the interference noise power of the source BWP and the broadband interference noise power of the target BWP.

[0154] Specifically, this step involves calculating the difference between the broadband interference noise power of the target BWP and the interference noise power of the source BWP, which is used as the first interference noise power change.

[0155] Step S143a: Map the first interference noise power change to the first downlink MCS change before and after BWP handover.

[0156] Specifically, with downlink transmit power configuration and link loss remaining constant, the change in interference noise power is equivalent to the change in signal-to-noise ratio (SNR). Therefore, the first change in interference noise power is defined as the first change in SNR, which is the difference between the broadband SNR of the target BWP and the SNR of the source BWP.

[0157] The first downlink MCS change refers to the change between the downlink MCS of the target BWP and the downlink MCS of the source BWP. In one embodiment of the present invention, after obtaining the first signal-to-noise ratio change, a mapping relationship between the signal-to-noise ratio change and the MCS change is established based on product performance to obtain the first downlink MCS change.

[0158] Step S144a: Based on the downlink MCS of the source BWP and the change in the first downlink MCS, obtain the downlink MCS of the target BWP's bandwidth.

[0159] In one embodiment of the present invention, the downlink MCS of the target BWP is denoted as MCS_DL_WideBand.

[0160] by Figure 2 To illustrate this step, with BWP1 as the source BWP and BWP2 as the target BWP, the change between the detected interference noise power of BWP1 and the broadband interference noise power of BWP2 confirmed by the method provided in this embodiment is calculated. The first interference noise power change is mapped to the first downlink MCS change. Assuming the obtained first downlink MCS change is ΔMCS and the detected downlink MCS of BWP1 is MCS_DL_0, the broadband downlink MCS of BWP2 can be obtained by considering ΔMCS based on MCS_DL_0.

[0161] The method for calculating the downlink MCS of a subband of a target BWP is similar to the method for calculating the downlink MCS of a broadband area. The following explanation uses the method for determining the downlink MCS of the i-th subband as an example, and includes the following steps:

[0162] Step S141b: Obtain the interference noise power and downlink MCS of the source BWP.

[0163] Step S142b: Determine the change in the second interference noise power before and after BWP switching based on the interference noise power of the source BWP and the interference noise power of the subband of the target BWP.

[0164] Step S143b: Map the second interference noise power change to the second downlink MCS change before and after BWP handover.

[0165] Step S144b: Based on the downlink MCS of the source BWP and the change in the second downlink MCS, obtain the downlink MCS of the target BWP's subband.

[0166] In one embodiment of the present invention, the downlink MCS of the i-th sub-band of the target BWP is denoted as MCS_DL_Sub-band_i.

[0167] Since the calculation of the downlink MCS for both broadband and subband is based on the same principle, the specific details involved can be found in the descriptions in steps S141a-S144a.

[0168] It is worth noting that the above steps are merely illustrative and not intended to limit the order of operations in actual applications. For example, the downlink MCS may be calculated first, followed by the uplink MCS. In one possible embodiment of the invention, steps S141-S144 are executed first, followed by steps S121-S130. Alternatively, the calculation of the uplink and downlink MCS may be processed in parallel.

[0169] This invention, in calculating the downlink MCS of a target BWP, utilizes the symmetry between uplink and downlink channels. It uses the uplink detected bandwidth and subband interference noise power to replace the downlink bandwidth and subband interference noise power. The change in interference noise power between the source BWP and the target BWP bandwidth and subband interference noise power is then identified as the signal-to-noise ratio (SNR) change. This SNR change is further mapped to the downlink MCS change, determining the target BWP bandwidth and subband downlink MCS based on the source BWP's downlink MCS. This eliminates the need for step-by-step independent calculation of the target BWP's bandwidth and subband SNR and downlink MCS, improving the efficiency of downlink MCS determination while maintaining accuracy.
