Description

Technical Field

[0001] The present application relates to the field of mobile communication technology, and in particular to a method, a base station and a terminal for improving the rate of a new air interface terminal. Background Art

[0002] To achieve smooth evolution from 4G (the 4th Generation Mobile Communication Technology) to 5G (the 5th Generation Mobile Communication Technology), operators use the strategy of dynamic spectrum sharing between 4G and 5G at the 2.1GHz frequency to balance the capacity of 4G and 5G. The DSS (Dynamic Spectrum Sharing) technology enables dynamic spectrum sharing between 4G and 5G, which can meet the respective traffic needs of 4G / 5G users on limited spectrum resources.

[0003] In the 1:1 configuration of NR (New Radio) and LTE (Long Term Evolution) under 40M bandwidth DSS, 40M NR terminals use full bandwidth or fixed sub-bandwidth to report CQI (Channel Quality Indicator) within 40M. The bandwidth of the overlapping part of 20M LTE and NR is dynamically variable, and there is interference from LTE CRS (Cell Reference Signal). Therefore, the 40M DSS base station is scheduled based on the full-bandwidth CQI or the fixed-sub-bandwidth CQI, which will cause the 40M NR terminal rate to drop due to inaccurate CQI, seriously affecting the NR performance and capacity in DSS.

[0070] In the embodiments of the present invention, the term "and / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent three situations: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0071] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0072] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0073] Reference Figure 1 The embodiment of the present application provides a method for improving the terminal rate of the new air interface, which is used to solve the problem in the prior art that when the DSS base station is scheduled based on the full-bandwidth CQI or the fixed sub-bandwidth CQI, the 40M NR terminal rate decreases due to inaccurate CQI, which seriously affects the NR performance and capacity in the DSS.

[0074] Among them, the method and the corresponding base station and terminal are based on the same application concept. Since the principles of solving the problems by the method and the corresponding base station and terminal are similar, the implementation of the base station, terminal and method can refer to each other, and the repeated parts will not be repeated.

[0075] In order to facilitate understanding of the method for improving the rate of a new air interface terminal in an embodiment of the present invention, the following contents are first introduced:

[0076] like Figure 2 As shown, in order to reduce the conflict of channels and signals between LTE and NR, the 40M DSS base station places the NR SSB (Synchronization Signal and PBCH block) in the 20M band outside the LTE 20M, but there is LTE CRS interference in the 20M overlapping part of LTE and NR. In the existing technical solution, the NR terminal is based on the CQI reported by the full bandwidth or fixed sub-bandwidth, and the 40M DSS base station is scheduled based on the full bandwidth CQI or fixed sub-bandwidth CQI reported by the NR terminal. Since the bandwidth of the overlapping part of LTE and NR is dynamically variable, the full bandwidth CQI or fixed sub-bandwidth CQI reported by the NR terminal is inaccurate, resulting in the 40M DSS base station scheduling based on the inaccurate full bandwidth CQI or fixed sub-bandwidth CQI, which will cause the 40M NR terminal rate to decrease.

[0077] Reference Figure 1 , shows a flowchart of a method for improving the rate of a new air interface terminal provided by an embodiment of the present application. In the embodiment of the present application, the method is applied to the base station side, and the method may include the following steps:

[0078] Step 101: obtain a first channel quality indication reported by a new radio interface NR terminal for a first type of bandwidth; the first type of bandwidth is an NR exclusive bandwidth.

[0079] The base station can send a first CSI-RS (Channel State Information-Reference Signal) measurement signal for the first type of bandwidth to the NR terminal, so that the NR terminal measures the first channel quality indication of the first type of bandwidth and reports the first channel quality indication to the base station; for the convenience of description, the first channel quality indication can also be represented by a first CQI.

[0080] Step 102: Obtain a second channel quality indication reported by the NR terminal for a second type of bandwidth, and a current bandwidth of the second type of bandwidth; the second type of bandwidth is a shared bandwidth between NR and the long term evolution network standard LTE.

[0081] The base station can send the second CSI-RS measurement information for the second type of bandwidth to the NR terminal, so that the NR terminal measures the second channel quality indication of the second type of bandwidth and reports the second channel quality indication to the base station. In addition, the NR terminal can also detect the current bandwidth of the second type of bandwidth. Since the second type of bandwidth is a shared bandwidth between NR and LTE, the current bandwidth of the second type of bandwidth refers to the instantaneous bandwidth of the second type of bandwidth occupied by the NR terminal. For the convenience of description, the second channel quality indication can also be represented by the first CQ2.

[0082] Step 103: Based on the current bandwidth, weighted processing is performed on the first channel quality indication and the second channel quality indication to obtain an overall channel quality indication of the NR terminal.

[0083] After obtaining the current bandwidth, the first channel quality indication, and the second channel quality indication, the base station can perform weighted processing on the first channel quality indication and the second channel quality indication based on the current bandwidth, and use the result of the weighted processing as the overall channel quality indication of the NR terminal. For the convenience of description, the overall channel quality indication can also be expressed as an overall CQI.

[0084] Step 104: adjust the modulation and coding strategy for the NR terminal according to the overall channel quality indication.

[0085] After determining the overall channel quality indication of the NR terminal, the base station adjusts the adjustment coding strategy for the NR terminal according to the overall channel quality indication. Since the determination process of the overall channel quality indication is obtained by weighting the first channel quality indication of the first type of bandwidth and the second channel quality indication of the second type of bandwidth based on the current bandwidth, compared with the prior art, which directly obtains the CQI based on the full bandwidth or the CQI of the fixed sub-bandwidth, the overall channel quality indication obtained in this embodiment can eliminate or reduce LTE CRS interference, that is, the overall channel quality indication obtained in this embodiment is highly accurate, and the base station schedules based on the overall channel quality indication with high accuracy, which can ensure that the scheduling result is conducive to improving the NR terminal rate.

[0086] In an embodiment of the present application, the base station obtains a first channel quality indication reported by a new air interface NR terminal for a first type of bandwidth; obtains a second channel quality indication reported by the NR terminal for a second type of bandwidth, and the current bandwidth of the second type of bandwidth; wherein the first type of bandwidth is the NR exclusive bandwidth, and the second type of bandwidth is the NR and LTE shared bandwidth; based on the current bandwidth, the first channel quality indication and the second channel quality indication are weighted to obtain an overall channel quality indication of the NR terminal; the accuracy of the determined overall channel quality indication can be effectively improved; finally, the modulation and coding strategy for the NR terminal is adjusted according to the overall channel quality indication; on the basis of ensuring the accuracy of the overall channel quality indication, the modulation and coding strategy is adjusted according to the overall channel quality indication, so as to ensure that the adjusted modulation and coding strategy is conducive to improving the NR terminal rate.

[0087] The method for increasing the new air interface terminal rate in this exemplary embodiment will be further described below.

[0088] To facilitate the understanding of those skilled in the art, the base station in the following example can be understood as a 40M DSS base station. Figure 3 As shown in the figure, the 40M DSS base station divides the 40M bandwidth into 20M NR exclusive bandwidth and 20M NR and LTE shared bandwidth. Among them, the 20M NR exclusive bandwidth can be called the first type of bandwidth in this embodiment, and the 20M NR and LTE shared bandwidth can be called the second type of bandwidth in this embodiment; and the NR bandwidth occupied by the NR terminal in the 20M NR and LTE shared bandwidth is the instantaneous bandwidth or the instantaneous variable bandwidth or the variable bandwidth, which can be called the current bandwidth in this embodiment, that is, Figure 3 The xM in , where xM is dynamically variable and its range is between [0, 20M].

[0089] In step 101, a first channel quality indication reported by a new radio interface NR terminal for a first type of bandwidth is obtained; the first type of bandwidth is an NR exclusive bandwidth.

[0090] The 40M DSS base station can send a first CSI-RS measurement signal for the first type of bandwidth (20M NR exclusive bandwidth) to the NR terminal, so that the NR terminal measures the first channel quality indication of the first type of bandwidth and reports the first channel quality indication to the 40M DSS base station; the first channel quality indication corresponds to Figure 3 CQI1 in. Therefore, the 40M DSS base station can obtain the first channel quality indication reported by the NR terminal for the first type of bandwidth. Among them, the CSI-RS measurement information is used to instruct the NR terminal to measure CSI-RS. CSI-RS is a very important reference signal in the 5G NR system. The wireless channel conditions may change continuously. The NR terminal needs to feed back the measured downlink channel conditions to the 40M DSS base station through CSI, so that the 40M DSS base station can take the channel quality into account during downlink scheduling.

[0091] Exemplarily, after receiving the first CSI-RS measurement signal, the NR terminal starts to measure the CSI-RS of the 20M NR exclusive bandwidth, evaluates the downlink characteristics according to the measurement results, such as the SINR (Signal to Noise or Interference Radio) value of the CSI-RS, and uses the internal algorithm of the NR terminal to determine the BLER (BLock Error Rate) value that can be obtained under this SINR. Generally, the BLER value is less than or equal to 10%; then find the corresponding MCS (Modulation and Coding Scheme) level through BLER, for example, find the corresponding MCS according to the EESM (Exponential Effective SINR Mapping) model; then obtain the first channel quality indication of the 20M NR exclusive bandwidth by looking up the table according to the MCS level. After obtaining the first channel quality indication of the first type of bandwidth, the NR terminal reports the first channel quality indication to the 40M DSS base station.

[0092] In step 102, a second channel quality indication reported by the NR terminal for a second type of bandwidth and a current bandwidth of the second type of bandwidth are obtained; the second type of bandwidth is a shared bandwidth between NR and the long term evolution network standard LTE.

[0093] Similar to step 101, the 40M DSS base station can send the second CSI-RS measurement information for the second type of bandwidth (20M NR and LTE shared bandwidth) to the NR terminal, so that the NR terminal measures the second channel quality indication of the second type of bandwidth of the NR and LTE shared bandwidth, and reports the second channel quality indication to the 40M DSS base station; the second channel quality indication corresponds to Figure 3 CQI2 in.

[0094] In addition, the NR terminal can also detect the current bandwidth of the second type of bandwidth and report the current bandwidth to the 40MDSS base station. The current bandwidth of the second type of bandwidth refers to the instantaneous bandwidth of the second type of bandwidth occupied by the NR terminal. The current bandwidth corresponds to Figure 3 Therefore, the 40M DSS base station can obtain the second channel quality indicator and the current bandwidth of the second type of bandwidth.

[0095] In an optional embodiment of the present application, before obtaining the first channel quality indication reported by the new air interface NR terminal for the first type of bandwidth, it also includes: the 40M DSS base station can send resource allocation information and scheduling information to the NR terminal, so that the NR terminal determines the current bandwidth of the second type of bandwidth based on the resource allocation information and scheduling information.

[0096] Exemplarily, the 40M DSS base station can also send the resource allocation and scheduling information of the uplink PUSCH (Physical Uplink Shared Channel) and the downlink PDSCH (Physical Downlink Shared Channel) to the NR terminal through the DCI (Data Communication Interface) of the PDCCH. After receiving the information sent by the 40M DSS base station, the NR terminal calculates and detects the instantaneous bandwidth x value of the second type of bandwidth occupied by the NR terminal through the RB (Resource Block) position and number N. The x value is also called the current bandwidth of the second type of bandwidth. After calculating the current bandwidth of the second type of bandwidth, the NR terminal reports the current bandwidth to the 40M DSS base station.

[0097] Among them, the formula for the NR terminal to calculate the current bandwidth of the second type of bandwidth can be: occupied bandwidth = subcarrier width * number of subcarriers per RB * number of RBs. For example, 12 consecutive subcarriers in frequency and one slot in the time domain are called 1 RB, that is, 1RB = 12 subcarriers. When the bandwidth of each subcarrier = 15K and the number of subcarriers per RB = 12; then x = 15*12*N / 1000 = 0.18N (MHz).

[0098] In step 103, based on the current bandwidth, the first channel quality indication and the second channel quality indication are weighted to obtain an overall channel quality indication of the NR terminal.

[0099] After obtaining the current bandwidth, the first channel quality indication, and the second channel quality indication, the 40M DSS base station can perform weighted processing on the first channel quality indication and the second channel quality indication based on the current bandwidth, and use the result of the weighted processing as the overall channel quality indication of the NR terminal, thereby improving the accuracy of the overall channel quality indication through weighted processing.

[0100] In an optional embodiment of the present application, the process of performing weighted processing on the first channel quality indication and the second channel quality indication based on the current bandwidth to obtain the overall channel quality indication of the NR terminal may include:

[0101] Determining, according to the current bandwidth, a first weighting coefficient corresponding to the first channel quality indication and a second weighting coefficient corresponding to the second channel quality indication;

[0102] The first channel quality indication and the second channel quality indication are weighted according to the first weighting coefficient and the second weighting coefficient to obtain an overall channel quality indication of the NR terminal.

[0103] In this embodiment, considering that there is LTE CRS interference in the shared bandwidth of 20M NR and LTE, the current bandwidth of the shared bandwidth of 20M NR and LTE changes instantaneously, and the corresponding interference also changes instantaneously. The 40M DSS base station determines the contribution of the second channel quality indication to the overall channel quality indication according to the current bandwidth of the shared bandwidth of 20M NR and LTE, thereby accurately eliminating the dynamic variable interference influence of the second channel quality indication of the interfered part in the overall channel quality indication, improving the accuracy of the overall channel quality indication, and thus improving the performance and capacity of the NR terminal in the 40M DSS base station.

[0104] Preferably, in the above-mentioned determining the first weighting coefficient corresponding to the first channel quality indicator and the second weighting coefficient corresponding to the second channel quality indicator according to the current bandwidth, the calculation formula corresponding to the first weighting coefficient is as follows:

[0105] W1 = 20 / (20+x);

[0106] Wherein, W1 represents the first weighting coefficient, x represents the current bandwidth, that is, the instantaneous bandwidth of the 20M NR and LTE shared bandwidth, and the range of x is [0, 20M].

[0107] The calculation formula corresponding to the second weighting coefficient is as follows:

[0108] W2=x / (20+x);

[0109] Wherein, W2 represents the second weighting coefficient, x represents the current bandwidth, that is, the instantaneous bandwidth of the 20M NR and LTE shared bandwidth, and the range of x is [0, 20M].

[0110] In this embodiment, the weighting coefficients of the first channel quality indication of the 20M NR exclusive bandwidth and the second channel quality indication of the 20M NR and LTE shared bandwidth are determined according to the corresponding respective bandwidth sizes. According to the maximum and minimum fairness and accuracy principles, the larger the corresponding bandwidth and the greater the signal capability, the greater the weight (weighting coefficient); conversely, the smaller the corresponding bandwidth and the smaller the signal capability, the smaller the weight (weighting coefficient); the accuracy of the overall channel quality indication calculated based on the first weighting coefficient and the second weighting coefficient can be ensured. Exemplarily, the calculation formula corresponding to the overall channel quality indication is as follows:

[0111] CQI(v)=W1*CQI1+W2*CQI2;

[0112] Among them, CQI(v) represents the overall channel quality indicator, CQI1 represents the first channel quality indicator, and CQI2 represents the second channel quality indicator.

[0113] It should be noted that, in other implementations, the overall channel quality indication may also be calculated in other ways, for example, by determining the first weighting coefficient and the second weighting coefficient through methods such as AI (Artificial Intelligence) or big data to calculate the overall channel quality indication. Exemplarily, when the big data method is used to calculate the overall channel quality indication, the period of the NR terminal measuring the first channel quality indication and the second channel quality indication may be shortened, the number of measurements of the first channel quality indication and the second channel quality indication may be increased, and the average value and variance of the first channel quality indication and the second channel quality indication may be counted. A large variance in the first channel quality indication and the second channel quality indication indicates a large interference, that is, a small SINR, and the corresponding weight (weighting coefficient) is relatively small.

[0114] In step 104, the modulation and coding strategy for the NR terminal is adjusted according to the overall channel quality indication.

[0115] After determining the overall channel quality indication of the NR terminal, the 40M DSS base station adjusts the adjustment coding strategy for the NR terminal according to the overall channel quality indication. Since the overall channel quality indication is determined by weighting the first channel quality indication of the first type of bandwidth and the second channel quality indication of the second type of bandwidth based on the current bandwidth, compared with the prior art, which directly obtains the CQI based on the full bandwidth or the CQI of the fixed sub-bandwidth, the overall channel quality indication obtained in this embodiment can eliminate or reduce LTE CRS interference, that is, the overall channel quality indication obtained in this embodiment is highly accurate, and the 40M DSS base station is scheduled based on the overall channel quality indication with high accuracy, which can ensure that the scheduling result is conducive to improving the NR terminal rate.

[0116] The process of the 40M DSS base station determining the corresponding modulation and coding strategy according to the overall channel quality indication may include:

[0117] First, obtain the amount of data to be transmitted, which can be expressed in bits (bits, a binary unit); determine the MPR (Modulation order Product Rate) corresponding to the overall channel quality indication; use MPR to calculate the required number of RE (Resource Element) to allocate resources and obtain the number of RBs; then, by looking up the table, find the table of RB and TBS (Transport Block Size) in the 38.213 protocol to find the corresponding TBS; finally, use TBS to find the table of MCS and TBS, determine MCS, and perform precision scheduling of data modulation and coding for NR terminals based on the determined MCS. The overall channel quality indication determined by this embodiment has high accuracy, so the 40MDSS base station can obtain accurate channel quality to dynamically adjust the scheduling strategy, thereby increasing the NR terminal rate, improving the performance and capacity of NR in DSS, and improving the 5G user experience.

[0118] In order to reduce the amount of calculation of the 40M DSS base station and avoid going through a series of processes of determining the modulation and coding strategy corresponding to the overall channel quality indication when there is no need to adjust the current modulation and coding strategy, in an optional embodiment of the present application, the above-mentioned adjustment of the modulation and coding strategy for the NR terminal according to the overall channel quality indication may include:

[0119] Obtaining a preset channel quality indicator corresponding to the current modulation and coding strategy;

[0120] When the overall channel quality indication does not meet the preset channel quality indication, determining a new modulation and coding strategy according to the overall channel quality indication;

[0121] The new modulation and coding strategy is adopted to replace the current modulation and coding strategy.

[0122] In this embodiment, the 40M DSS base station obtains the preset channel quality indication corresponding to the current modulation and coding strategy of the NR terminal, and compares the obtained overall channel quality indication with the preset channel quality indication. If the overall channel quality indication is within the range of the preset channel quality indication, it means that the current modulation and coding strategy does not need to be adjusted and the current modulation and coding strategy can continue to be maintained; if the overall channel quality indication is not within the preset channel quality indication range, it means that the current modulation and coding strategy needs to be modulated. At this time, a new modulation and coding strategy is determined according to the overall channel quality indication. The determination process can be found in the previous description and will not be repeated. After determining the new modulation and coding strategy corresponding to the overall channel quality indication, the new modulation and coding strategy is used to replace the current modulation and coding strategy to increase the NR terminal rate and enhance the 5G user experience.

[0123] In summary, the embodiments of the present invention have the following advantages:

[0124] 1. According to the 20M NR in 40M DSS and the NR variable bandwidth size in the LTE shared bandwidth (i.e., the current bandwidth), the weighting coefficient is dynamically adjusted to calculate the overall channel quality indication, thereby improving the accuracy of the overall channel quality indication and effectively solving the problem of rate drop of 40M NR terminals in the 1:1 configuration of NR and LTE under 40M DSS in the prior art.

[0125] 2. By combining the first channel quality indication of fixed bandwidth (i.e., first type of bandwidth) and the second channel quality indication of variable bandwidth (i.e., second type of bandwidth), the interference impact of LTE CRS in the overall channel quality indication can be accurately and dynamically eliminated or reduced, thereby improving the NR network capacity and performance in 40M DSS.

[0126] 3. The overall channel quality indication determination method provided in the embodiment of the present application is not limited to the 40M DSS base station. Therefore, it greatly improves the flexibility of DSS networking, improves resource utilization, reduces network construction costs and DSS operation and maintenance and optimization costs.

[0127] 4. This embodiment can effectively improve the 4G and 5G user experience by ensuring the accuracy of the overall channel quality indication and performing scheduling based on the highly accurate overall channel quality indication.

[0128] Reference Figure 4, shows a flowchart of the steps of a method for improving the rate of a new air interface terminal provided by an embodiment of the present application. In the embodiment of the present application, the method is applied to the new air interface NR terminal side, wherein the base station corresponding to the NR terminal includes a first type of bandwidth and a second type of bandwidth, the first type of bandwidth is the NR terminal exclusive bandwidth, and the second type of bandwidth is the NR and LTE shared bandwidth. The method may include the following steps:

[0129] Step 401: determine the current bandwidth of the second type of bandwidth corresponding to the base station; the second type of bandwidth is a shared bandwidth between NR and the long term evolution network standard LTE.

[0130] In an embodiment of the present application, the NR terminal needs to determine the current bandwidth (also called instantaneous bandwidth) size of the shared bandwidth occupied by the NR terminal, so as to subsequently determine the overall channel quality indication of the NR terminal based on the current bandwidth.

[0131] Step 402: determine a first channel quality indicator of a first type of bandwidth of the base station and a second channel quality indicator of the second type of bandwidth; the first type of bandwidth is an NR exclusive bandwidth.

[0132] In an embodiment of the present application, the NR terminal needs to report the CQI in segments, and therefore, it is necessary to determine the first channel quality indication of the first type of bandwidth and the second channel quality indication of the second type of bandwidth.

[0133] Step 403: Report the first channel quality indication, the second channel quality indication and the current bandwidth to the base station, so that the base station determines the overall channel quality indication of the NR terminal based on the first channel quality indication, the second channel quality indication and the current bandwidth, and adjusts the adjustment coding strategy for the NR terminal according to the overall channel quality indication.

[0134] After determining the first channel quality indication, the second channel quality indication and the current bandwidth, the NR terminal sends the first channel quality indication, the second channel quality indication and the current bandwidth to the corresponding base station, so that the base station performs weighted processing on the first channel quality indication and the second channel quality indication based on the current bandwidth to obtain an overall channel quality indication, and then performs scheduling based on the overall channel quality indication.

[0135] In an embodiment of the present application, the NR terminal changes the method of reporting CQI based on full bandwidth or fixed sub-bandwidth in the prior art, by determining the current bandwidth of the second type of bandwidth of the corresponding base station; determining the first channel quality indication of the first type of bandwidth of the base station, and the second channel quality indication of the second type of bandwidth; reporting the first channel quality indication, the second channel quality indication and the current bandwidth to the base station, and realizing segmented reporting of the first channel quality indication based on the NR exclusive bandwidth and the second channel quality indication based on the NR and LTE shared bandwidth, and realizing detection and reporting of the current bandwidth of the NR and LTE shared bandwidth, so that the base station determines the overall channel quality indication of the NR terminal based on the first channel quality indication, the second channel quality indication and the current bandwidth, and adjusts the adjustment coding strategy for the NR terminal according to the overall channel quality indication, which can improve the NR terminal rate and improve user experience.

[0136] The method for increasing the new air interface terminal rate in this exemplary embodiment will be further described below.

[0137] To facilitate the understanding of those skilled in the art, the base station in the following example can be understood as a 40M DSS base station. Figure 3 As shown, the 40M DSS base station divides the 40M bandwidth into 20M NR exclusive bandwidth and 20M NR and LTE shared bandwidth. Among them, the 20MNR exclusive bandwidth can be called the first type of bandwidth in this embodiment, and the 20M NR and LTE shared bandwidth can be called the second type of bandwidth in this embodiment; and the NR bandwidth occupied by the NR terminal in the 20M NR and LTE shared bandwidth is the instantaneous bandwidth or the instantaneous variable bandwidth or the variable bandwidth, which can be called the current bandwidth in this embodiment.

[0138] In step 401, the current bandwidth of the second type of bandwidth of the corresponding base station is determined; the second type of bandwidth is a shared bandwidth of NR and long term evolution network standard LTE.

[0139] The NR terminal can determine the current bandwidth of the second type of bandwidth based on resource allocation information and scheduling information.

[0140] Exemplarily, the NR terminal can receive the resource allocation and scheduling information of the uplink PUSCH and downlink PDSCH sent by the 40M DSS base station, and calculate and detect the instantaneous bandwidth x value of the second type of bandwidth occupied by the NR terminal through the RB position and number N. The x value is also called the current bandwidth of the second type of bandwidth.

[0141] In step 402, a first channel quality indicator of a first type of bandwidth of the base station and a second channel quality indicator of the second type of bandwidth are determined; the first type of bandwidth is an NR exclusive bandwidth.

[0142] In an embodiment of the present application, the NR terminal can receive a first CSI-RS measurement signal for a first type of bandwidth (20M NR exclusive bandwidth) sent by a base station, and measure a first channel quality indication of the first type of bandwidth based on the first CSI-RS measurement signal, and send the first channel quality indication to the corresponding base station.

[0143] Exemplarily, after receiving the first CSI-RS measurement signal, the NR terminal starts to measure the CSI-RS of the 20M NR exclusive bandwidth, evaluates the downlink characteristics based on the measurement results, such as the SINR value of the CSI-RS, and uses the NR terminal internal algorithm to determine the BLER value that can be obtained under this SINR, and generally the BLER value is less than or equal to 10%; then find the corresponding MCS level through the BLER, for example, find the corresponding MCS according to the EESM model; then obtain the first channel quality indication of the 20M NR exclusive bandwidth through a table lookup based on the MCS level.

[0144] Similarly, after receiving the second CSI-RS measurement signal, the NR terminal can measure and obtain the second channel quality indication of the second type of bandwidth.

[0145] In step 403, the first channel quality indication, the second channel quality indication and the current bandwidth are reported to the base station, so that the base station determines the overall channel quality indication of the NR terminal based on the first channel quality indication, the second channel quality indication and the current bandwidth, and adjusts the adjustment coding strategy for the NR terminal according to the overall channel quality indication.

[0146] After determining the first channel quality indication, the second channel quality indication and the current bandwidth, the NR terminal reports the first channel quality indication, the second channel quality indication and the current bandwidth to the 40M DSS base station. The 40M DSS base station can determine the overall channel quality indication of the NR terminal based on the first channel quality indication, the second channel quality indication and the current bandwidth, and adjust the adjustment coding strategy for the NR terminal according to the overall channel quality indication. Among them, the 40M DSS base station determines the overall channel quality indication of the NR terminal based on the first channel quality indication, the second channel quality indication and the current bandwidth, and adjusts the adjustment coding strategy for the NR terminal according to the overall channel quality indication. For example, Figure 1 The step flow chart shown and the method embodiment for improving the new air interface terminal rate applied to the base station side mentioned above will not be repeated here.

[0147] In an embodiment of the present application, the NR terminal changes the method of reporting CQI based on the full bandwidth or fixed sub-bandwidth in the prior art, and reports the first channel quality indication based on the NR exclusive bandwidth and the second channel quality indication based on the NR and LTE shared bandwidth in segments, as well as reporting the current bandwidth of the NR and LTE shared bandwidth, so that the base station can implement the effects of the embodiment of the method for improving the new air interface terminal rate as applied to the base station side as mentioned above, including increasing the NR terminal rate and improving user experience.
