Description

Method and device for determining number of overlapping layers and transmitting information, transmitting equipment and storage medium

Technical Field

The present application relates to the field of wireless communications, and in particular, to a method, an apparatus, a transmitting device, and a storage medium for determining the number of overlapping layers and transmitting information.

Background

An overlapping Time Division Multiplexing (OVTDM) system forms a novel coding scheme with high coding gain and high spectral efficiency by shifting and overlapping the Multiplexing waveform of data in the Time domain. In an OVTDM system, overlap between adjacent symbols is deliberately introduced, and it is considered that mutual overlap between data symbols inside the system is not interference, but a beneficial coding constraint relationship, and only destructive factors from outside the system are interference. If this overlap is exploited reasonably, it will not only degrade system performance, but can provide additional performance gains.

Compared with the traditional OFDM system, the multi-carrier OVTDM system formed by combining the OVTDM technology and the multi-carrier Orthogonal Frequency Division Multiplexing (OFDM) system can greatly improve the data rate.

However, Inter-subcarrier Interference (ICI) exists in a multi-Carrier OVTDM system, and the existence of ICI has a serious impact on system performance.

Detailed Description

The present application will be described in further detail with reference to the following drawings and examples.

Assuming that the duration of a transmitted Symbol is T, in a conventional nyquist transmission system, data is transmitted only once in the duration of T in order to ensure orthogonality between signals, thereby avoiding Inter Symbol Interference (ISI) caused by overlapping of transmitted data. Fig. 1 is a schematic transmission diagram of an OVTDM system. As shown in fig. 1, in the OVTDM system, compared to the nyquist orthogonal transmission system, the transmission interval becomes 1/K, so the transmission rate is increased by K times, where K is the number of overlapping layers of the OVTDM system. OVTDM waveform coding is similar to convolutional codes, all by superimposing bits after delay. The convolutional code delay is an integer multiple of the symbol period T, while the OVTDM system delay is 1/K of the symbol period T.

When K is equal to 2, the corresponding relationship between the input and output symbols of the OVTDM system is as shown in fig. 2. As can be appreciated from fig. 2, the OVTDM system takes the waveform as the multiplexing dimension, which, although it destroys the one-to-one correspondence between the input data and the output symbols, still preserves the one-to-one correspondence between the input data sequences and the shifted overlapping output sequences. The essence of the OVTDM technique is a multiplexing technique, in which waveforms corresponding to a plurality of data streams are shifted in time domain or frequency domain, so that differences in the waveforms are artificially formed and are superimposed for transmission.

On the other hand, combining the OVTDM technique with a multi-carrier OFDM system to form a multi-carrier OVTDM system, as shown in fig. 3, a specific implementation scheme of a transmitting end includes: after modulation (namely symbol mapping) is carried out on bit streams generated by an information source, serial-to-parallel conversion is carried out, K-layer superposition is carried out on parallel data symbols of each path in each chip by using an OVTDM technology after molding and filtering, the superposed data is respectively modulated onto a plurality of orthogonal subcarriers, then parallel-to-serial conversion is carried out on the parallel data symbols of each path, and transmission is carried out after cyclic prefix and digital-to-analog conversion are inserted. In the multi-carrier OVTDM system, the transmission interval of the modulation symbols on each subcarrier is shortened to T/K, so that the data rate can be increased by K times compared with the traditional OFDM system.

However, in the conventional OFDM system, the peak of each subcarrier spectrum corresponds to exactly the zero of the other subcarrier spectrum, thereby ensuring orthogonality between subcarriers. However, in the multi-carrier OVTDM system, since K layers of shift overlap are introduced on each sub-carrier, ISI is introduced into data of the sub-carrier, and a spectrum peak of a current sub-carrier does not correspond to a zero point of other waveforms, that is, ICI is generated. Although ISI in a multi-carrier OVTDM system can be removed by inserting a cyclic prefix and viterbi decoding at the receiving end, the presence of ICI can still have a severe impact on system performance. Especially when pilot frequency exists in the system, the existence of ICI can cause significant interference between the RE where the pilot frequency is located and the RE where the OVTDM data is located. The influence on the pilot frequency is more obvious, and particularly, the accuracy of operations such as channel estimation based on the pilot frequency, demodulation and decoding of a receiving end and the like is seriously influenced.

Based on this, in various embodiments of the present application, for a multi-carrier OVTDM system with a pilot frequency, on a resource where a plurality of OVTDM data adjacent to a resource frequency domain where the pilot frequency is located are located, the number of OVTDM overlapping layers corresponding to the resource where the plurality of OVTDM data are located is reduced, for example, from K layers to 1 layer, and the number of overlapping layers of each second resource on each multi-carrier OVTDM symbol is adaptively selected according to channel quality, thereby reducing the influence of ICI. Namely, the resource where the OVTDM data is located is used as a guard band, so that the ICI influence on the resource where the pilot frequency is located is reduced.

An embodiment of the present application provides a method for determining a number of overlapping layers, which is applied to a multi-carrier OVTDM system, that is, the embodiment of the present application provides a method for determining a number of overlapping layers in a multi-carrier OVTDM system, which is specifically applied to a sending device, and as shown in fig. 4, the method includes:

step 401: acquiring the channel quality of a first resource where a pilot frequency is located;

step 402: determining the number of overlapping layers of the second resource where each data in the first symbol is located by using the obtained channel quality of the first resource; wherein the content of the first and second substances,

Wherein, in practical application, the first resource and the second resource may be represented by an RE. In this case, the second resource may be referred to as a data RE.

Here, the data RE means: the REs in which the OVTDM data is transmitted, i.e., the REs in which the OVTDM data is located.

In actual application, the first resource does not carry out overlapping transmission; k denotes the number of overlapping layers set in advance in the multicarrier OVTDM system.

In a multi-carrier OVTDM system, one symbol generally includes 12 REs, i.e., the number of data REs and pilot REs in one symbol is generally 12.

The transmitting device may be a base station or a terminal.

In practical applications, the number of overlapping layers may also be referred to as the number of overlapping multiplexing layers.

As shown in fig. 5, assuming that the first resource and the second resource are represented as REs, N second resources adjacent to the first resource in the frequency domain refer to: in one symbol, N/2 data REs before and after the RE frequency domain where the pilot is located, for example, assuming that N is 2, 2 second resources adjacent to the first resource frequency domain mean: 1 data RE before and after the RE where the pilot frequency is located; for another example, if N is 4, the 4 second resources adjacent to the first resource frequency domain refer to: and 2 data REs before and after the RE where the pilot frequency is located. In fig. 5, RS denotes a pilot.

In practical application, the sending device needs to acquire a pilot pattern of a resource block of the multi-carrier OVTDM system, and accordingly initializes the type of the OVTDM second resource, so as to adaptively select the number of overlapping layers of each second resource on each multi-carrier OVTDM symbol according to channel quality.

Based on this, in an embodiment, before step 401, the method may further include:

determining a pilot frequency pattern in a resource block in the OVTDM system;

correspondingly, the type of each second resource in the first symbol is adjusted by using the acquired channel quality of the first resource, and the number of overlapping layers of each second resource in the first symbol is indirectly determined due to the fact that different types correspond to different numbers of overlapping layers.

Exemplarily, the type of all the second resources on the multicarrier OVTDM symbol without the pilot frequency may be set to be TypeA-RE, and K-layer OVTDM transmission is performed, that is, the number of overlapping layers of all the second resources on the multicarrier OVTDM symbol without the pilot frequency is K; setting the type of second resources which are normally used for K-layer OVTDM transmission on a multi-carrier OVTDM symbol containing pilot frequency as TypeB-RE (namely, a second type), namely, the number of overlapped layers of the second resources is K; the type of the second resource for performing 1-layer OVTDM transmission on the multicarrier OVTDM symbol containing the pilot is set to be TypeC-RE (i.e. the first type), i.e. the number of overlapping layers of these second resources is 1.

As shown in fig. 6, assuming that the manifestation of the first resource and the second resource is REs, when initializing the type of OVTDM data REs, for a multi-carrier OVTDM symbol that does not contain pilot, the types of all data REs thereon are all set to type-REs; for the multicarrier OVTDM symbol with the pilot frequency, the type of each 1 OVTDM data RE before and after the frequency domain adjacent to the pilot frequency RE is set as TypeC-RE, and the type of the rest OVTDM data RE in the multicarrier OVTDM symbol is set as TypeB-RE. In fig. 6, RS denotes a pilot, a denotes data REs of type TypeA-RE, B denotes data REs of type TypeB-RE, and C denotes data REs of type TypeC-RE.

When OVTDM transmission is carried out, the type of each second resource in each symbol is self-adaptively adjusted according to the channel quality, and therefore the number of the overlapped layers of each second resource on each multi-carrier OVTDM symbol is self-adaptively selected.

In an embodiment, when determining the number of overlapping layers of each second resource in the first symbol by using the obtained channel quality of the first resource, the method may include:

and determining the value of N according to the comparison result.

Specifically, when the obtained channel quality of the first resource is greater than a first threshold, the value of N is determined to be a first value.

Under the condition that the obtained channel quality of the first resource is larger than a second threshold and smaller than or equal to a first threshold, the determined N value is a second value;

Wherein the first threshold is greater than a second threshold; the first value is less than the second value.

That is to say, when the channel quality of the first resource is good, the value of N is smaller, for example, 1, and when the channel quality of the first resource is general, the value of N is larger, for example, 4, and when the channel quality of the first resource is very poor, all the second resources on the first symbol may be set as a guard band, and perform 1-layer OVTDM transmission, where the value of N is Q.

Exemplarily, assuming that the first resource and the second resource are represented by REs, taking the RE type shown in fig. 6 as an example, if the channel quality of the RE where the pilot is located is greater than the first threshold, this indicates that the channel quality of the RE where the pilot is located is better, and the value of N is 2, at this time, the number and the position of TypeC-REs in data REs adjacent to the frequency domain of the RE where the pilot is located do not need to be adjusted, and meanwhile, the number and the position of data REs of TypeA-REs and TypeB-REs also do not need to be adjusted. In this case, each pilot RE only needs two adjacent data REs as a guard band, i.e., can protect the correct transmission of the pilot.

If the channel quality of the RE where the pilot frequency is located is greater than the second threshold and less than or equal to the first threshold, it indicates that the channel quality of the RE where the pilot frequency is located is general, the value of N is 4, the types of 2 data REs before and after the frequency domain of the data RE adjacent to the frequency domain of the RE where the pilot frequency is located are set to be TypeC-RE, the number of data REs of TypeB-RE is correspondingly reduced, and the number and position of data REs of TypeA-RE do not need to be changed, as shown in fig. 7. In this case, each pilot RE needs 2 data REs before and after the frequency domain as a guard band, thereby reducing the ICI effect and ensuring correct transmission of the pilot. In fig. 7, RS indicates a pilot, a indicates data RE of type TypeA-RE, B indicates data RE of type TypeB-RE, and C indicates data RE of type TypeC-RE.

If the channel quality of the RE where the pilot frequency is located is greater than the second threshold and less than or equal to the first threshold, it indicates that the channel quality of the RE where the pilot frequency is located is general, the value of N is 12, at this time, all types of data REs on the multicarrier OVTDM symbol where the pilot frequency RE is located are set to be TypeC-RE, the number of data REs of TypeB-RE is correspondingly reduced, and the number and position of data REs of TypeA-RE do not need to be changed, as shown in fig. 8. In this case, all data REs on the multicarrier OVTDM symbol with the pilot are set as the guard band, and 1-layer OVTDM transmission is performed to achieve the protection of the pilot, thereby reducing the ICI effect. In fig. 8, RS denotes a pilot, a denotes data REs of type TypeA-RE, B denotes data REs of type TypeB-RE, and C denotes data REs of type TypeC-RE.

In practical applications, the first threshold and the second threshold may be set as needed. The first and second values may also be set as desired.

In an embodiment, the channel quality of the first resource may be characterized by at least one of the following parameters:

SNR；

SINR；

RSRP；

RSRQ。
