Description
Technical Field
The present invention relates to the field of wireless communications, and in particular, to a data transmission method, apparatus, related device, and storage medium.
Background
In a digital communication system, in order to improve frequency efficiency, data to be transmitted may be encoded using an overlapping X Division Multiplexing (OVXDM) technique. OVXDM is a novel coding technology which forms high spectral efficiency, no coding residue and high coding gain by shifting and overlapping data weighting multiplexing waveforms in an X domain; the X domain includes a time domain, a frequency domain, a mixed domain, or the like. For example, OVTDM may be formed by implementing shift overlap in the time domain; shift superposition is realized in the frequency domain, and OVFDM can be formed; and realizing shift overlapping in a mixed domain, and forming OVHDM.
For the uplink, there are cases where multiple terminals concurrently transmit data, which may specifically include two cases, the first case: the network device only receives data sent by one terminal in each time period, however, the spectrum efficiency is low when the scheme is adopted for multi-user data transmission. In the second case: each terminal uses the respective overlap number to perform OVXDM coding on data to be transmitted and independently sends the coded data to network equipment, however, the adoption of the scheme for multi-user data transmission easily generates interference and can increase the decoding processing complexity of the network equipment;
based on this, how to use OVXDM to perform multi-user data transmission becomes a technical problem which needs to be solved urgently.

Detailed Description
In the related art, in a digital communication system, in order to improve frequency efficiency, data to be transmitted may be encoded using an overlap multiplexing OVXDM technique. OVXDM is a novel coding technology which forms high spectral efficiency, no coding residue and high coding gain by shifting and overlapping data weighting multiplexing waveforms in an X domain; the X domain includes a time domain, a frequency domain, a mixed domain, or the like. For example, implementing shift overlap in the time domain, OVTDM may be formed, as shown in fig. 1; shift superposition is realized in the frequency domain, and OVFDM can be formed; and realizing shift overlapping in a mixed domain, and forming OVHDM. In practical application, as shown in fig. 2, OVXDM may be implemented by using a waveform convolution coding model, and the sending end device may use the following formula:
calculating a complex envelope waveform of a transmitted signal
Wherein the content of the first and second substances,
the envelope waveform obtained by shifting the initial envelope waveform in the time domain at preset intervals is represented. For the uplink, there are cases where multiple terminals concurrently transmit data, which may specifically include two cases, the first case: the network device receives data transmitted by only one terminal in each time period, however, the scheme is adoptedAnd multi-user data transmission is carried out, and the spectrum efficiency is lower. In the second case: each terminal uses the respective overlap repetition number to perform OVTDM coding on data to be transmitted and independently transmits the coded data to network equipment, however, interference is easily generated when the scheme is adopted to perform multi-user data transmission, and thus, the network equipment is not easy to perform decoding processing to recover the data of each terminal;
how to use OVXDM for multi-user data transmission in the above manner becomes a technical problem which needs to be solved urgently.
Based on this, in the embodiment of the present invention, the information related to the overlapping multiple is notified to at least two terminals; the overlapping number is the overlapping number shared by the at least two terminals; and the overlapping weight number related information is used for the at least two terminals to carry out OVXDM coding on the data to be transmitted.
The present invention will be described in further detail with reference to the accompanying drawings and examples.
An embodiment of the present invention provides a data transmission method applied to a network device, and as shown in fig. 3, the method includes:
step 301: and informing the information related to the overlapping weight to at least two terminals.
Wherein the overlapping number is the overlapping number shared by the at least two terminals; and the overlapping weight number related information is used for the at least two terminals to carry out OVXDM coding on the data to be transmitted.
Here, the overlap multiple related information is used to indicate the number of multiplexing waveforms used by each of the at least two terminals when performing OVXDM coding.
Here, the at least two terminals may refer to at least two terminals currently scheduled by the network device.
In practical application, the network device may send Downlink Control information to the at least two terminals through a Physical Downlink Control Channel (PDCCH), so that the network device may carry the information related to the overlapping weights in the Downlink Control information and send the information to the at least two terminals.
Based on this, in an embodiment, the notifying the information related to the overlapping multiple to at least two terminals includes: and notifying the information related to the overlapping weight to at least two terminals through the downlink control information.
In practical application, in order to enable the at least two terminals to share the overlap number, the shared overlap number may be segmented according to the number of the terminals, each terminal corresponds to one overlap number segment, each overlap number segment includes one start-stop overlap number, and the start-stop overlap number corresponding to each terminal is sent to the corresponding terminal.
Based on this, in an embodiment, the method further comprises: determining, for each of the at least two terminals, a first overlap count corresponding to the respective terminal; determining the starting and stopping overlapping weight number corresponding to the corresponding terminal by using the first overlapping weight number; and generating the overlapping weight related information based on the starting and stopping overlapping weight.
For example, assuming that the number of overlapping times K shared is equal to 10, the terminals UE1, UE2, and UE3 share the number of overlapping times K, the first number of overlapping times corresponding to UE1 may be 3, the start-stop number of overlapping times corresponding to UE1 may be 1 and 3, the first number of overlapping times corresponding to UE2 may be 5, the start-stop number of overlapping times corresponding to UE 358 may be 4 and 8, the first number of overlapping times corresponding to UE3 may be 2, and the start-stop number of overlapping times corresponding to UE3 may be 9 and 10.
In practical application, in order to enable the at least two terminals to share the overlap number, the shared overlap number may be segmented according to the overlap number corresponding to each terminal, each terminal corresponds to one first overlap number and one starting overlap number, and the first overlap number and the starting overlap number corresponding to each terminal are sent to the corresponding terminals.
Based on this, in an embodiment, the method further comprises: determining, for each of the at least two terminals, a first overlap count corresponding to the respective terminal; determining the starting overlapping weight number corresponding to the corresponding terminal by using the first overlapping weight number; generating the overlapping weight related information based on the starting overlapping weight and the first overlapping weight.
Here, the first overlap multiple is equal to a number indicating a multiplexing waveform used by the corresponding terminal when performing OVXDM coding.
For example, assuming that the overlap number K is equal to 7, and the terminals UE1, UE2, and UE3 share the overlap number K, the starting overlap number corresponding to UE1 may be 1, the ending overlap number may be 2, and the first overlap number is: 2-1+1 ═ 2; the UE2 may have a starting overlap count of 4, an ending overlap count of 6, and a first overlap count of: 6-4+1 ═ 3; the UE1 may have a starting overlap count of 5, an ending overlap count of 7, and a first overlap count of: 7-5+1 ═ 3.
Here, since the at least two terminals share the overlap count, the start-stop overlap count corresponding to each terminal may be quantized using the same quantization bits as the shared overlap count.
In practical application, it is considered that if the uplink channel quality between the terminal and the network device is high, the spectral efficiency of the terminal for encoding data to be transmitted by using OVXDM is high, and therefore, when the uplink channel quality between each terminal and the network device meets a preset condition, the corresponding overlap multiple is determined.
Based on this, in an embodiment, determining a first overlap count corresponding to a respective terminal includes: determining the quality of an uplink channel between a corresponding terminal and the network equipment; determining the overlapping weight number corresponding to the uplink channel quality according to the corresponding relation between the uplink channel quality and the overlapping weight number; and taking the determined overlapping weight number as a first overlapping weight number corresponding to the corresponding terminal.
For example, table 1 is a corresponding relationship between the uplink channel quality and the overlap number, and as shown in table 1, the uplink channel quality between the corresponding terminal and the network device may be determined; when the uplink channel quality is greater than the threshold value 1, it may be determined that the first overlap multiple corresponding to the terminal is 2; when the uplink channel quality is greater than the threshold 2, it may be determined that the first overlap multiple corresponding to the terminal is 3; when the uplink channel quality is greater than the threshold 3, it may be determined that the first overlap multiple corresponding to the terminal is 5; when the uplink channel quality is greater than the threshold 4, it may be determined that the first overlap multiple corresponding to the terminal is 6. It should be noted that the number of the threshold values may be set according to actual situations.
| Quality of uplink channel | First overlap weight |
| The quality of the uplink channel is greater than the |
2 |
| The quality of the uplink channel is greater than the |
3 |
| The quality of the uplink channel is greater than the threshold 3 | 5 |
| The quality of the uplink channel is greater than the threshold 4 | 6 |
TABLE 1
In practical applications, since the at least two terminals share the overlap ratio, the starting overlap ratio corresponding to each terminal may be quantized using the same quantization bits as the shared overlap ratio, and the first overlap ratio corresponding to each terminal may be quantized using fewer quantization bits than the shared overlap ratio.
Based on this, in an embodiment, the generating the overlapping weight related information based on the starting overlapping weight and the first overlapping weight includes: determining a first quantization bit and a second quantization bit; quantizing the starting overlap multiplicity using a first quantization bit; quantizing the first overlap multiplicity using a second quantization bit.
Wherein a number of bits of the first quantization bit is greater than a number of bits of the second quantization bit.
For example, assuming that the shared overlap may be quantized by Nbit, and the terminals UE1, UE2, and UE3 share the overlap K, taking UE1 as an example, assuming that the starting overlap is 3 and the first overlap is 4, the starting overlap may be quantized by N-4 bits and the first overlap may be quantized by M-3 bits.
In practical application, after the network device notifies the information related to the overlapping multiplicity to at least two terminals, each of the at least two terminals may perform OVXDM coding on data to be transmitted, and send the coded OVXDM coding to the network device.
Based on this, in an embodiment, the method further comprises: receiving data sent by a terminal; the data is obtained by the terminal performing OVXDM coding on a sending sequence by using the overlapping weight related information; and carrying out OVXDM decoding on the data based on the overlapping weight related information corresponding to the terminal to obtain decoded data.
Here, after receiving the data sent by the at least two terminals, the network device may perform OVXDM decoding on the data sent by the corresponding terminal by using the first overlap number corresponding to the corresponding terminal in the at least two terminals and the overlap number shared by the at least two terminals, so as to recover the data of all the terminals, thereby improving the accuracy of decoding.
It should be noted that, here, the network device may receive the data sent by the at least two terminals in the same time period, so that the spectrum efficiency can be improved; the at least two terminals can share the overlap number, and perform OVXDM coding on the sending sequence by using the corresponding overlap number related information and send the coded sequence to the network equipment, so that the occurrence of overlapping of multiplexing waveforms used by a plurality of terminals can be avoided when multi-user data transmission is performed, and the complexity of decoding is reduced.
By adopting the technical scheme of the embodiment of the invention, because the at least two terminals can share the overlapping number, the at least two terminals can utilize the information related to the overlapping number to carry out OVXDM coding on data to be transmitted, thereby improving the frequency spectrum efficiency. In addition, because the at least two terminals can share the overlapping repetition number, interference is not easy to generate when multi-user data transmission is carried out, and thus, the network equipment can recover the data of all the terminals, and the accuracy rate of decoding is improved.
An embodiment of the present invention provides a data transmission method, which is applied to a terminal, and as shown in fig. 4, the method includes:
step 401: and receiving the related information of the overlapping weight sent by the network equipment.
Here, the overlap number is a number of overlaps shared by at least two terminals.
Here, the overlap number-related information is used to indicate the number of multiplexed waveforms used by the terminal when performing OVXDM coding.
In practical application, after the terminal receives the overlapping weight related information sent by the network device, the terminal may perform OVXDM coding on data to be transmitted, and send the coded data to the network device.
Based on this, in an embodiment, the method further comprises: determining a time interval for shifting an initial envelope waveform of a transmission sequence by using the overlapping multiplicity related information; shifting the initial envelope waveform according to the determined time interval to obtain a shifted envelope waveform; carrying out OVXDM coding on the sending sequence by using the shifted envelope waveform to obtain coded data; and sending the encoded data to the network equipment.
Here, the terminal may implement OVXDM using a waveform convolution coding model and calculate a complex envelope waveform of a transmission signal according to equation (1)
Wherein the content of the first and second substances,
which represents an envelope waveform obtained by shifting an initial envelope waveform in the time domain at certain time intervals.
