[0058] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0059] In the following description, reference is made to “some embodiments”, which describe a subset of all possible embodiments, but it can be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0060] In the following description, the terms "first\second" involved are merely used to distinguish similar objects and do not represent a specific ordering of the objects. It can be understood that "first\second" can be interchanged with a specific order or sequence where permitted, so that the embodiments of the present disclosure described herein can be implemented in an order other than that illustrated or described herein.

[0061] Unless otherwise defined, all technical and scientific terms used in this disclosure have the same meaning as those commonly understood by those skilled in the art to which this disclosure belongs. The terms used in this disclosure are only for the purpose of describing the embodiments of this disclosure and are not intended to limit this disclosure.

[0062] It should be understood that in the various embodiments of the present disclosure, the size of the serial number of each implementation process does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present disclosure.

[0063] Figure 1 A first optional flow chart of a data transmission method in the related art is shown.

[0064] With the development of communication technology, multi-antenna transmission is used to improve throughput. Figure 1 As shown, the terminal reports the signal quality information to the base station. The base station modulates and layer-maps the data according to the signal quality information, and then modulates it into a radio frequency signal and transmits it through the antenna. When the terminal is in a weak signal area, the four antennas transmit the same data content, and the four antennas of the terminal also receive the same data. This is to use multiple antennas to enhance the downlink receiving sensitivity to ensure normal reception and demodulation of the required data.

[0065] Figure 2 A second optional flow chart of a data transmission method in the related art is shown.

[0066] When the terminal is in a strong signal area and needs to download large data, the base station modulates and maps the data, and then divides the data into 4 signals through serial-to-parallel conversion. These 4 signals are then modulated into RF signals and transmitted through the base station antenna. At this time, the four antennas transmit 1 / 4 of the data content respectively. The data content transmitted by each antenna is different, and the four antennas on the terminal side also receive 1 / 4 different data accordingly. Finally, the 4 data are demodulated and merged inside the terminal. Under the same modulation mode, Figure 2 The throughput of the scheme shown is Figure 1 4 times the throughput of the solution shown.

[0067] However, due to differences in antenna efficiency between multiple antennas on the terminal side, and in different usage scenarios, such as holding the phone in hand or in different folding states, the efficiency of some antennas varies significantly. Figure 2 In the scheme shown (i.e. each antenna transmits different data content), there may be a situation where a certain antenna cannot receive data or the received data has a high bit error rate and cannot be demodulated, which will affect the overall throughput.

[0068] In view of the defects existing in the related art, the embodiments of the present disclosure provide a data transmission method, which has solved some or all of the above-mentioned technical problems.

[0069] Figure 3 A first optional flow chart of the data transmission method provided by an embodiment of the present disclosure is shown, and will be explained according to each step.

[0070] Step S301: receiving antenna signal quality information sent by a terminal.

[0071] In some embodiments, the antenna signal quality information may include the channel quality or signal quality of each of the multiple antennas of the terminal, or the channel quality and signal quality. Among them, the channel quality includes the channel's effectiveness in signal transmission, which will be affected by noise, fading (multipath fading and shadow fading) and bandwidth limitations. Signal quality refers to whether the characteristics of the signal itself meet the requirements, focusing on the parameters and characteristics of the signal itself; the quality of the signal affects the correct reception and interpretation of information. Factors affecting signal quality include signal strength, stability and modulation method.

[0072] In some embodiments, the base station may periodically receive antenna signal quality information sent by the terminal; it may also obtain antenna signal quality information actively reported by the terminal before there is a downlink data flow on the terminal side; it may also send an antenna signal quality information acquisition indication to the terminal before there is a downlink data flow on the terminal side, and receive antenna signal quality information returned by the receiving terminal based on the antenna signal quality information acquisition indication.

[0073] It should be noted that the terminal antenna involved in the embodiments of the present disclosure is a cellular communication antenna, that is, an antenna for transmitting communication data with a base station. The communication data involved in the embodiments of the present disclosure may include, but is not limited to, one of the third generation mobile communication (3G) data, the fourth generation mobile communication (4G) data, the fifth generation mobile communication (5G) data, and the sixth generation mobile communication (6G) data. The communication data may also include communication data based on cellular network communication technology. The data involved in the embodiments of the present disclosure is communication data.

[0074] Step S302: confirming the modulation mode and data ratio corresponding to each antenna of the base station based on the antenna signal quality information.

[0075] In some embodiments, the antenna of the base station corresponds to the antenna of the terminal one-to-one, that is, the signal sent by antenna A on the base station side will be received by antenna a on the terminal side; the signal sent by antenna B on the base station side will be received by antenna b on the terminal side. Therefore, the downlink data can be divided into n parts according to different proportions according to the antenna signal quality information on the terminal side. The higher (or better) the antenna signal quality information of the antenna on the terminal side, the greater the proportion of downlink data received, and correspondingly, the greater the proportion of downlink data sent by the corresponding antenna on the base station side and the higher the order of the modulation mode; the lower (or worse) the antenna signal quality information of the antenna on the terminal side, the smaller the proportion of downlink data received, and correspondingly, the smaller the proportion of downlink data sent by the corresponding antenna on the base station side and the lower the order of the modulation mode.

[0076] In the related art, the lower the order of the modulation mode, the lower the required signal-to-noise ratio, and the lower the bit error rate under the same conditions. For example, the signal-to-noise ratio requirement: BPSK<QPSK<16QAM<64QAM; under the same signal-to-noise ratio, the bit error rates are BPSK, QPSK, 16QAM, and 64QAM from small to large. Therefore, for antenna signal quality information with low quality, select a low-order modulation mode (such as BPSK, QPSK) so that it can have a low bit error rate under low signal-to-noise ratio conditions; for antenna signal quality with high quality, select a high-order modulation mode (such as 64QAM) so that it can achieve a large amount of downlink data transmission while ensuring the bit error rate under high signal-to-noise ratio conditions.

[0077] Step S303: divide the data based on the data ratio corresponding to each antenna, and modulate the divided data according to the corresponding modulation method.

[0078] In some embodiments, the data is divided based on the data ratio determined in step S302 to confirm the data corresponding to each antenna of the base station (i.e., the data to be sent by each antenna of the base station) and the modulation mode corresponding to the data; the data corresponding to each antenna is modulated based on the modulation mode to obtain the modulated data.

[0079] Step S304: sending the modulated data to the terminal based on the corresponding antenna.

[0080] In some embodiments, the modulated data corresponding to each antenna is modulated onto a corresponding radio frequency signal, and the radio frequency signal is sent through the antenna.

[0081] Specifically, it is assumed that there are 4 antennas on the base station side participating in downlink data transmission: antenna A, antenna B, antenna C and antenna D; based on step S302, the data ratio transmitted by each antenna is determined, and the downlink data is divided into sub-data a, sub-data b, sub-data c and sub-data d according to the data ratio, wherein the data amounts of sub-data a, sub-data b, sub-data c and sub-data d are not exactly the same; sub-data a, sub-data b, sub-data c and sub-data d are modulated respectively according to the modulation mode determined in step S302 to obtain modulated sub-data a1, modulated sub-data b1, modulated sub-data c1 and modulated sub-data d1, and the modulated sub-data a1 is modulated to the radio frequency band corresponding to antenna A, the modulated sub-data b1 is modulated to the radio frequency band corresponding to antenna B, the modulated sub-data c1 is modulated to the radio frequency band corresponding to antenna C, and the modulated sub-data d1 is modulated to the radio frequency band corresponding to antenna D, and sent to the terminal.

[0082] In some embodiments, the above steps S301 to S304 may be implemented by a resource scheduling module disposed in the base station; the resource scheduling module is disposed between the layer mapping module and the radio frequency module.

[0083] In this way, through the data transmission method described in the embodiment of the present disclosure, the proportion and modulation mode of downlink data received by each antenna are determined according to the antenna signal quality information of each antenna of the terminal; based on the proportion of downlink data received by each antenna, the data is divided for the antennas participating in transmitting downlink data on the base station side, and modulated according to the modulation mode, and then sent to the terminal; in this way, the efficiency of each antenna of the terminal can be adapted to avoid the situation where the data bit error rate is too high, thereby improving the data throughput.

[0084] Figure 4 A second optional flow chart of the data transmission method provided in an embodiment of the present disclosure is shown, and will be described according to each step.

[0085] Step S401: receiving antenna signal quality information sent by a terminal.

[0086] In some embodiments, the base station may receive antenna signal quality information actively sent by the terminal; or, before transmitting downlink data to the terminal, send antenna signal quality information to the terminal, and receive antenna signal quality information returned by the terminal based on the obtained antenna signal quality information.

[0087] Step S402: confirming the modulation mode and data ratio corresponding to each antenna of the base station based on the antenna signal quality information.

[0088] In some embodiments, the base station side confirms the data ratio corresponding to each antenna of the base station based on the signal quality or channel quality received by each antenna of the terminal; and confirms the modulation mode corresponding to each antenna based on the data ratio corresponding to each antenna of the base station.

[0089] Among them, the antenna of the terminal corresponds one-to-one with the antenna of the base station. The higher the signal quality received by the antenna on the terminal side, the higher the data ratio of the corresponding antenna on the base station side; the higher the channel quality corresponding to the antenna on the terminal side, the higher the data ratio of the corresponding antenna on the base station side; the higher the data ratio of the antenna, the higher the order of the modulation method.

[0090] During specific implementation, the base station side can sort the antenna signal quality information of all antennas of the terminal, and determine the data ratio and modulation mode corresponding to each antenna according to the sorting result. The higher the antenna signal quality information is sorted, the higher the corresponding data ratio and the higher the modulation order. Optionally, the ratio can be a fixed ratio, such as sorting the antenna signal quality information from high to low among the four antennas in a ratio of 4:3:2:1. The base station side can allocate data to each antenna at a set ratio, or it can allocate data to each antenna on the base station side according to the specific antenna signal quality information of each antenna on the base station side.

[0091] Or in a specific implementation, the base station side can determine the data content and proportion sent by each antenna on the base station side based on a preset threshold and antenna signal quality information of all antennas of the terminal.

[0092] Specifically, it is confirmed that the base station side antenna corresponding to the antenna whose terminal side antenna signal quality is greater than the preset threshold value sends different content from the content sent by other antennas on the base station side; it is confirmed that the base station side antenna corresponding to the antenna whose terminal side antenna signal quality is less than or equal to the preset threshold value sends the same content as the content sent by at least one other antenna on the base station side. Further, the data division ratio is confirmed based on the antenna signal quality, wherein the number of data divisions is less than the total number of antennas on the base station side participating in downlink data transmission.

[0093] For example, the terminal side includes four cellular communication antennas, namely antenna a, antenna b, antenna c and antenna d, and the corresponding antennas on the base station side are antenna A, antenna B, antenna C and antenna D in sequence; confirm that the signal quality information of antenna a and antenna b is greater than a preset threshold, and the signal quality information of antenna c and antenna d is less than the preset threshold; then correspondingly, the data content sent by antenna A is different from the data content sent by the other three antennas; the data content sent by antenna B is different from the data content sent by the other three antennas; the data content sent by antenna C and antenna D is the same, but different from the data content sent by antenna A and antenna B. Further, based on the sorting results of the signal quality information of antenna a, antenna b, antenna c and antenna d, the data ratios of antenna A, antenna B, and antenna C and antenna D are determined; such as 5:3:2, that is, antenna A is responsible for sending 50% of the downlink data, antenna B is responsible for sending 30% of the downlink data, and antenna C and antenna D are responsible for sending 20% ​​of the downlink data (the data sent by antenna C and antenna D are the same).

[0094] In some optional embodiments, the base station side can also determine the data ratio of each antenna on the base station side based on the specific range of the signal quality information. The higher the transmission quality of the terminal side antenna represented by the signal quality information, the higher the data ratio of the corresponding base station side antenna. The lower the transmission quality of the terminal side antenna represented by the signal quality information, the lower the data ratio of the corresponding base station side antenna.

[0095] In some embodiments, when the base station side sorts the signal quality information, the signal quality information received by each antenna of the terminal can be sorted in a descending order to obtain a sorting result; based on the sorting result and a preset data ratio comparison table, the data ratio received by each antenna on the terminal side is confirmed; based on the data ratio received by each antenna on the terminal side, the data ratio sent by each antenna on the base station side is confirmed; the channel quality received by each antenna on the terminal side can also be sorted in a descending order to obtain a sorting result; based on the sorting result and a preset data ratio comparison table, the data ratio received by each antenna on the terminal side is confirmed; based on the data ratio received by each antenna on the terminal side, the data ratio sent by each antenna on the base station side is confirmed; it is also possible to weight the signal quality and channel quality received by each antenna on the base station side to obtain a weighted result, and sort the weighted results corresponding to each line on the terminal side in a descending order to obtain a sorting result; based on the sorting result and the preset data ratio comparison table, the data ratio received by each antenna on the terminal side is confirmed; based on the data ratio received by each antenna on the terminal side, the data ratio sent by each antenna on the base station side is confirmed.

[0096] In some embodiments, the base station side can determine the data modulation mode of each antenna participating in sending downlink data on the base station side based on the ranking result of the signal quality information of each antenna on the terminal side; it can also determine the data modulation mode of each antenna based on the data ratio of each antenna participating in sending downlink data on the base station side. For example, if the data ratio is higher, a higher-order modulation mode can be used to ensure that the downlink data is transmitted to the terminal at the same time.

[0097] Step S403: divide the data based on the data ratio corresponding to each antenna, and modulate the divided data according to the corresponding modulation method.

[0098] The specific step flow of step S403 is the same as that of step S303 and will not be repeated here.

[0099] Step S404: sending the modulated data to the terminal based on the corresponding antenna.

[0100] In some embodiments, the base station performs layer mapping (such as serial-to-parallel conversion) on the modulated data, and then maps the modulated data to the corresponding antenna port, modulates the data according to the RF frequency of different antennas, and transmits the modulated RF data through the antenna.

[0101] In some embodiments, the above steps S401 to S404 may be implemented by a resource scheduling device disposed in a base station; the resource scheduling device is disposed between the layer mapping module and the radio frequency module.

[0102] In this way, through the data transmission method described in the embodiment of the present disclosure, the proportion and modulation mode of downlink data received by each antenna are determined according to the antenna signal quality information of each antenna of the terminal; based on the proportion of downlink data received by each antenna, the data is divided for the antennas participating in transmitting downlink data on the base station side, and modulated according to the modulation mode, and then sent to the terminal; in this way, the efficiency of each antenna of the terminal can be adapted to avoid the situation where the data bit error rate is too high, thereby improving the data throughput.

[0103] Figure 5 A third optional flow chart of the data transmission method provided in the embodiment of the present disclosure is shown. Figure 6 The schematic diagram of the data processing flow at the base station side provided by the embodiment of the present disclosure is shown. Figure 5 and Figure 6 Provide explanation.

[0104] Step S501: The preprocessing module preprocesses the downlink data.

[0105] In some embodiments, the base station side may include a preprocessing module, a resource scheduling module, a radio frequency module and at least one antenna; the preprocessing module may include a channel coding unit and a layer mapping unit and may also include an interleaving unit, an inverse Fourier transform processing (IFFT) unit, a cyclic prefix (CP) unit, a windowing unit, a parallel-to-serial conversion unit and a digital-to-analog conversion processing unit.

[0106] In some embodiments, the preprocessing includes at least channel coding and layer mapping and may also include interleaving, inverse Fourier transform processing (IFFT), adding a cyclic prefix (CP), windowing, parallel-to-serial conversion and digital-to-analog conversion.

[0107] In some embodiments, the preprocessing module preprocesses the downlink data to be transmitted to the terminal, and then performs serial-to-parallel conversion on the encoded data, converting one signal into multiple signals. The "multiple" involved in the embodiments of the present disclosure includes two or more, for example, the multiple signals include 2 or more signals.

[0108] Step S502: The resource scheduling module receives antenna signal quality information sent by the terminal.

[0109] In some embodiments, the resource scheduling module receives antenna signal quality information sent by the terminal. The specific receiving method is the same as step S301 or step S401, and will not be repeated here.

[0110] In some embodiments, the resource scheduling module confirms the modulation mode and data ratio corresponding to each antenna of the base station based on the antenna signal quality information; the specific method of confirming the modulation mode and data ratio is the same as step S302 or step S402, and will not be repeated here.

[0111] In some embodiments, the resource scheduling module divides the data based on the data ratio corresponding to each antenna, and modulates the divided data according to the corresponding modulation method. The specific division method and modulation method are the same as step S303, and will not be repeated here.

[0112] Combination Figure 6 The downlink data sent by the preprocessing module to the resource scheduling module is {S1, S2, S3, S4, S5, S6, S7, S8}. Based on the antenna signal quality information, the resource scheduling module confirms that the data ratio corresponding to each antenna of the base station is 2:1:3:2, that is, antenna 1 transmits {S1, S2}, antenna 2 transmits {S3}, antenna 3 transmits {S4, S5, S6}, and antenna 4 transmits {S7, S8}. The data is modulated based on the modulation mode corresponding to each antenna.

[0113] Step S503: The radio frequency module modulates the data and sends it to the terminal through the antenna module.

[0114] In some embodiments, the RF module performs RF modulation on the data to obtain RF data. Specifically, based on the RF frequency corresponding to each antenna on the base station side, the data is modulated to the corresponding RF frequency, and then the RF data is sent to the terminal through the antenna module.

[0115] Specifically, Figure 6 For example, the RF frequency modulation corresponding to antenna 1 is {S1, S2}, the RF frequency modulation corresponding to antenna 2 is {S3}, the RF frequency modulation corresponding to antenna 3 is {S4, S5, S6}, and the RF frequency modulation corresponding to antenna 4 is {S7, S8}.

[0116] In this way, through the data transmission method described in the embodiment of the present disclosure, the proportion and modulation mode of downlink data received by each antenna are determined according to the antenna signal quality information of each antenna of the terminal; based on the proportion of downlink data received by each antenna, the data is divided for the antennas participating in transmitting downlink data on the base station side, and modulated according to the modulation mode, and then sent to the terminal; in this way, the efficiency of each antenna of the terminal can be adapted to avoid the situation where the data bit error rate is too high, thereby improving the data throughput.

[0117] Figure 7 A fourth optional flow chart of the data transmission method provided in the embodiment of the present disclosure is shown and will be explained according to each step.

[0118] Step S701: Send signal quality information of each of multiple antennas to a base station.

[0119] In some embodiments, the terminal sends signal quality information of each antenna among multiple antennas included in the terminal to the base station. The multiple antennas include cellular communication antennas; and the signal quality information includes signal quality, channel quality, and signal quality and channel quality.

[0120] In some optional embodiments, the base station may periodically send the signal quality information of each antenna to the base station, and may also send the signal quality information of each antenna to the base station before there is a downlink data flow demand; the signal quality information of each antenna may also be periodically confirmed, and when a change in the signal quality information of at least one antenna is greater than a first threshold, the antenna signal quality information is updated, and the updated antenna signal quality information is sent to the base station, so that the base station adjusts the modulation mode and data ratio corresponding to each antenna based on the updated antenna signal quality information; specifically, the signal quality information of each antenna may be sent to a resource scheduling module of the base station.

[0121] Step S702: Receive modulated data sent by the base station, and confirm the modulation mode corresponding to each antenna based on the signal quality information received by the antenna.

[0122] In some embodiments, the terminal can confirm the modulation mode corresponding to each antenna based on the data proportion, order and modulation mode carried by the signal header in the modulated data. Here, each antenna may include at least one antenna on the base station side that participates in sending the modulated data (i.e., downlink data), and may also include at least one cellular communication antenna on the terminal side.

[0123] In some other embodiments, the terminal may also confirm the modulation mode corresponding to each antenna in advance based on the signal quality information of each antenna in the terminal. The specific confirmation method is the same as that of the base station side.

[0124] Specifically, the terminal can sort the antenna signal quality information of all antennas of the terminal, and determine the data ratio and modulation mode corresponding to each antenna according to the sorting result. The higher the antenna signal quality information is sorted, the higher the corresponding data ratio and the higher the modulation order. Optionally, the ratio can be a fixed ratio, such as sorting the antenna signal quality information from high to low among the four antennas in a ratio of 4:3:2:1. The terminal can determine the amount of data received by each antenna with a set ratio, or determine the amount of data received by each antenna according to the specific antenna signal quality information of each antenna on the terminal side.

[0125] Alternatively, in a specific implementation, the terminal side may determine the data content and proportion sent by each antenna on the base station side based on a preset threshold and antenna signal quality information of all antennas of the terminal, and further determine the data content and proportion received by each antenna in the terminal.

[0126] In a specific implementation, the terminal confirms that the data content received by the antenna whose antenna signal quality is greater than the preset threshold is different from the data content received by other antennas; confirms that the data content received by the antenna whose antenna signal quality is less than or equal to the preset threshold is the same as the data content received by at least one other antenna. Further, the data division ratio is confirmed based on the antenna signal quality, wherein the number of data divisions is less than the total number of antennas participating in downlink data transmission of the terminal.

[0127] For example, the terminal includes four cellular communication antennas, namely antenna a, antenna b, antenna c and antenna d, and the corresponding antennas on the base station side are antenna A, antenna B, antenna C and antenna D in sequence; confirm that the signal quality information of antenna a and antenna b is greater than the preset threshold, and the signal quality information of antenna c and antenna d is less than the preset threshold; then correspondingly, the data content received by antenna a is different from the data content sent by the other three antennas; the data content received by antenna b is different from the data content sent by the other three antennas; the data content received by antenna c and antenna d is the same, but different from the data content received by antenna a and antenna b. Furthermore, based on the sorting results of the signal quality information of antenna a, antenna b, antenna c and antenna d, determine the data ratio of antenna a, antenna b, and antenna c and antenna d; such as 5:3:2, that is, antenna a is responsible for receiving 50% of the downlink data, antenna b is responsible for receiving 30% of the downlink data, and antenna c and antenna d are responsible for receiving 20% ​​of the downlink data (the data received by antenna c and antenna d are the same).

[0128] In some optional embodiments, the terminal can also determine the data ratio of each antenna based on the specific range of the signal quality information. The higher the transmission quality of the antenna on the terminal side represented by the signal quality information, the higher the data ratio of the antenna on the corresponding terminal side. The lower the transmission quality of the antenna on the terminal side represented by the signal quality information, the lower the data ratio of the antenna on the corresponding terminal side.

[0129] In some embodiments, when the terminal side sorts the signal quality information, it can sort the signal quality information received by each antenna of the terminal in order from high to low to obtain a sorting result; based on the sorting result and a preset data ratio comparison table, confirm the data ratio received by each antenna of the terminal; it can also sort the channel quality received by each antenna of the terminal in order from high to low to obtain a sorting result; based on the sorting result and the preset data ratio comparison table, confirm the data ratio received by each antenna of the terminal; it can also weight the signal quality and channel quality received by each antenna to obtain a weighted result, and sort the weighted results corresponding to each line of the terminal in order from high to low to obtain a sorting result; based on the sorting result and the preset data ratio comparison table, confirm the data ratio received by each antenna of the terminal.

[0130] In some embodiments, the terminal can determine the modulation mode corresponding to each antenna based on the ranking result of the signal quality information of each antenna of the terminal; or determine the data modulation mode of each antenna based on the data ratio of each antenna. For example, if the data ratio is higher, a higher-order modulation mode can be used to ensure that the downlink data is transmitted to the terminal at the same time.

[0131] Step S703: demodulate the modulated data based on the modulation mode corresponding to each antenna.

[0132] In some embodiments, the terminal demodulates the modulated data received by each antenna based on the modulation mode corresponding to each antenna.

[0133] In some optional embodiments, the terminal may further perform analog-to-digital conversion, serial-to-parallel conversion, CP removal, Fourier transform processing (FFT) and deinterleaving on the demodulated data to obtain original downlink data.

[0134] In this way, through the data transmission method provided by the embodiment of the present disclosure, the terminal side determines the corresponding received data ratio and modulation method based on each cellular communication antenna, and then performs demodulation and splicing processing to adapt the received data to the antenna efficiency, avoid the situation where the data bit error rate is too high, and improve the data throughput rate.

[0135] It should be noted that the method described in the embodiment of the present disclosure is also applicable to uplink data transmission, that is, the terminal side reports the antenna signal quality information of each antenna to the base station side, and the base station side and the terminal side confirm the modulation mode and data ratio corresponding to each antenna on the base station side and the terminal side based on the antenna signal quality information; and then perform data transmission, modulation, and demodulation based on the corresponding modulation mode and data ratio.

[0136] In some embodiments, the method described in the embodiments of the present disclosure is also applicable to a multiple-input multiple-output (MIMO) scenario.
