DETAILED DESCRIPTION

The embodiments of the present disclosure provide a communication method, device, and storage medium.

In a first aspect, an embodiment of the present disclosure provides a communication method, which is executed by a terminal. The method includes:

Acquire first information, where the first information is used to indicate a mapping type of a data bit sequence;

Mapping the data bit sequence into a symbol sequence according to the mapping type, where symbols of different amplitudes in the symbol sequence correspond to b data bits in different states in the data bit sequence, where b is a positive integer;

The symbol sequence is transmitted.

In the above embodiment, the terminal performs amplitude modulation on the data bit sequence based on the mapping type, that is, mapping the data bit sequence into a symbol sequence. The network device can dynamically indicate the mapping type. Amplitude modulation can achieve greater diversity gain and higher reliability in the Khatri-Rao domain, thereby enhancing uplink coverage.

In combination with some embodiments of the first aspect, in some embodiments, every b data bits in the data bit sequence are mapped to N _RF symbols, the N _RF symbols have the same amplitude, and N _RF is a positive integer.

In the above embodiment, when amplitude modulation is performed, every b data bits are mapped to N _RF symbols with the same amplitude. The N _RF symbols carry the same data bits, so that the receiving end (network device) performs spatial domain filtering.

In conjunction with some embodiments of the first aspect, in some embodiments, the amplitudes of the N _RF symbols satisfy at least one of the following:

The mapping type is the first mapping type, and the amplitude of the N _RF symbols is one of the 2 ^b amplitudes with the smallest amplitude in the constellation diagram;

The mapping type is the second mapping type, and the amplitude of the N _RF symbols is one of the 2 ^b amplitudes with the largest amplitude in the constellation diagram;

The mapping type is the third mapping type, and the amplitude of the N _RF symbols is one of the 2 ^b amplitudes in the constellation diagram that satisfies the maximum minimum difference between amplitudes.

When performing amplitude modulation, in some embodiments, the mapping type is the first mapping type, which minimizes the total transmit power of the terminal to save power consumption. In some embodiments, the mapping type is the second mapping type, which maximizes the total transmit power of the terminal to avoid the receiving end being unable to receive the signal due to insufficient transmit power and further improve uplink coverage. In some embodiments, the mapping type is the third mapping type, which increases the amplitude interval of the modulation symbols to improve the reliability and accuracy of the receiving end's decision. The network device can dynamically indicate the mapping type, for example, instructing the terminal to use a certain mapping type based on the terminal's location in the network.

In combination with some embodiments of the first aspect, in some embodiments, the mapping relationship between every b data bits and amplitude is Gray mapping.

The transceiver module is configured to send the symbol sequence.

In a fourth aspect, an embodiment of the present disclosure provides a communication device, including:

The transceiver module is configured to send first information to the terminal, where the first information is used to indicate a mapping type of a data bit sequence, where the mapping type is used to map the data bit sequence into a symbol sequence, where symbols of different amplitudes in the symbol sequence correspond to b data bits in different states in the data bit sequence, where b is a positive integer; and is also configured to receive the symbol sequence.

Multiple-antenna technology, also known as multiple-input, multiple-output (MIMO) technology, can achieve spatial diversity and spatial multiplexing. Spatial diversity can significantly improve the reliability of communication links, while spatial multiplexing can greatly increase the spectral efficiency of communication links. MIMO technology is a key physical layer transmission technology, including 4G LTE systems, 5G NR systems, and even future wireless communication systems (such as 6G communication systems).

Currently, multi-antenna arrays are primarily uniform arrays, such as the common one-dimensional uniform linear array (ULA) and two-dimensional uniform planar array (UPA). In addition to uniform arrays, there are also sparse arrays. The individual antenna elements (element groups) in a sparse array are non-uniformly distributed, such as the common minimum redundancy array (MRA) and Golomb array. Compared to uniform arrays, sparse arrays have the following advantages: 1) With the same number of antenna elements, sparse arrays can achieve a larger antenna aperture, thereby obtaining higher spatial resolution; 2) With the same antenna aperture, sparse arrays have fewer antenna elements, fewer RF channels, lower power consumption, and less mutual coupling between antennas.

In cellular communication systems, uplink coverage has always been a bottleneck due to the limited transmit power of user equipment (UE). To enhance uplink coverage, the 4G LTE system introduced the DFT-s-OFDM waveform. This waveform has a low peak-to-average power ratio (PAPR), allowing for smaller power backoff during power amplification to achieve higher transmit power. Therefore, the DFT-s-OFDM waveform continues to be used in 5G NR systems.

The UL of 5G NR supports both CP-OFDM and DFT-s-OFDM waveforms, and switches between them. For example, when the UE is at the edge of the cell, the DFT-s-OFDM waveform is used; when the UE is at the center of the cell, the CP-OFDM waveform is used.

However, supporting both DFT-s-OFDM and CP-OFDM waveforms simultaneously has certain drawbacks: 1) DFT-s-OFDM is not well-suited for multi-layer transmission, whether for single-user or multi-user use. Currently, the DFT-s-OFDM waveform only supports single-layer transmission. 2) The DFT-s-OFDM waveform requires specialized processing distinct from the CP-OFDM waveform, such as operations related to the Demodulation Reference Signal (DMRS) and the Phase Tracking Reference Signal (PTRS). This significantly increases system complexity and cost, leading to the need for unified waveforms and operations.

In order to solve the problem of supporting both DFT-s-OFDM and CP-OFDM waveforms at the same time, in some embodiments, the terminal can dynamically switch between quadrature amplitude modulation (QAM) and amplitude modulation (AM), and use a unified waveform (such as CP-OFDM waveform) for uplink transmission, which can reduce the complexity and cost of the system. Amplitude modulation can obtain greater diversity gain and higher reliability in the Khatri-Rao domain, and achieve uplink coverage enhancement under the unified CP-OFDM waveform. Compared with the uplink (UL) that supports both CP-OFDM and DFT-s-OFDM waveforms at the same time, it can be achieved through CP-OFDM solves uplink coverage issues with a single waveform, avoiding the problems caused by the introduction of the DFT-s-OFDM waveform. Network equipment can dynamically indicate the modulation method on the terminal side. For example, for terminals at the cell edge, it can instruct them to use amplitude modulation to achieve enhanced uplink coverage. For example, for terminals at the cell center, it can instruct them to use orthogonal amplitude modulation to achieve high-speed uplink transmission.

If the modulation mode is amplitude modulation, the terminal performs amplitude modulation on the data bit sequence, thereby mapping the data bit sequence into a symbol sequence. Symbols of different amplitudes in the symbol sequence correspond to b data bits in different states in the data bit sequence, where b is a positive integer. For example, b data bits have ^2b different states, corresponding to ^2b different amplitudes. Optionally, b can be predefined or configured by the network device. For example, b can be predefined in the protocol or predefined by the terminal.

In some embodiments, if the modulation mode is amplitude modulation, the terminal maps each b data bits in the data bit sequence into N _RF symbols, where the N _RF symbols have the same amplitude, and N _RF is a positive integer. Optionally, N _RF can be predefined or configured by the network device. For example, N _RF is predefined in the protocol or predefined _by the terminal.

In some embodiments, amplitude modulation may be performed based on a constellation diagram method, that is, every b data bits in a data bit sequence are mapped to N _RF symbols.

Based on the amplitude in the constellation diagram, when mapping b data bits to N _RF symbols, the amplitude of the N _RF symbols is one of the amplitudes in the above constellation diagram, q(M) is the number of amplitudes in the constellation, and M is the number of constellation points in the constellation. For example, for a QAM constellation with order M (i.e., number of constellation points), there are q(M) different amplitudes. Taking 16QAM as an example, there are q(16) = 3 different amplitudes. Taking 64QAM as an example, there are q(64) = 9 different amplitudes. In particular, if q(M) is an integer power of 2, then Therefore, every maximum bits are mapped to N _RF symbols, and the amplitudes of N _RF symbols are the same, that is, each b data bits are mapped to one amplitude. Optionally, each b data bits are mapped to one of 2 ^b amplitudes among the q(M) amplitudes of the QAM constellation.

Taking 64QAM as an example, there are q(64)=9 different amplitudes in total, and a maximum of 3 data bits are mapped to one amplitude. For example, every 3 data bits can be mapped to one amplitude among 8 amplitudes (8 amplitudes in the 64QAM constellation diagram), or every 2 data bits can be mapped to one amplitude among 4 amplitudes (4 amplitudes in the 64QAM constellation diagram).

In some embodiments, the amplitudes of the N _RF symbols are determined by a mapping relationship between b data bits and amplitudes. The phases of each of the _{N RF} symbols may be the same or different.

In some embodiments, the amplitude of the N _RF symbols is recorded as amplitude 1, and each of the N _RF symbols is determined from a constellation symbol (constellation point) in the constellation diagram corresponding to amplitude 1. Optionally, each of the N _RF symbols is independently randomly selected from a constellation symbol in the QAM constellation diagram having an amplitude of amplitude 1.

In some embodiments, the phase of each of the N _RF symbols is a random phase within [0, 2π). Optionally, the phases of the N _RF symbols are independent of each other. Optionally, the phase of each of the N _RF symbols is a random phase uniformly distributed within [0, 2π).

In the above embodiment, the phase of each of the N _RF symbols may be randomly determined, or each of the N _RF symbols may be a constellation symbol in a QAM constellation diagram.

In some embodiments, based on the amplitude in the QAM constellation diagram, the The amplitude corresponding to the b data bits in the QAM constellation diagram is amplitude one, and N _RF constellation symbols are independently randomly selected from the constellation symbols with amplitude one in the QAM constellation diagram, thereby mapping the b data bits to N _RF symbols.

In some embodiments, based on the amplitude in the QAM constellation diagram, the The amplitude corresponding to the b data bits in the QAM constellation is amplitude 1. Based on amplitude 1 and a random phase uniformly distributed in [0, 2π), N _RF symbols are determined, thereby mapping the b data bits to N _RF symbols. In the above embodiment, only the amplitude state in the QAM constellation is used.

In some embodiments, the network device sends second information to the terminal, where the second information includes at least one of the following:

b;

N _RF .

Optionally, the second information includes b, that is, the network device configures b for the terminal through the second information. If the network device does not configure b for the terminal, b can take a default value, such as Optionally, the second information does not include b. For example, when b is predefined or takes a default value, the second information does not include b.

Optionally, the second information includes N _RF , meaning the network device configures the N _RF for the terminal using the second information. If the network device does not configure the N _RF for the terminal, the N _RF may take a default value. Optionally, the second information does not include N _RF , for example, when the N _RF is predefined or takes a default _value .

In the above technical solution, when mapping each b data bit to N _RF symbols, the b data bits need to be mapped to one of the 2 ^b amplitudes among the q(M) amplitudes of the QAM constellation. Therefore, when q(M) is greater than 2 ^b , it is necessary to select 2 ^b amplitudes from the q(M) amplitudes and map each b data bit in the data bit sequence to one of the selected 2 ^b amplitudes. The above technical solution faces the problem of how to select 2 ^b amplitudes from the q(M) amplitudes.

FIG2 is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2 , the embodiment of the present disclosure relates to a communication method, which includes:

Step S2101: The network device sends first information to the terminal, where the first information is used to indicate a mapping type of a data bit sequence.

In some embodiments, the name of the first information is not limited, and it can be, for example, "amplitude modulation type (AMT)", "mapping indication information", etc.

In some embodiments, the first information is carried in downlink control information (DCI) including an uplink scheduling grant. For example, an indication field is added to the DCI including the uplink scheduling grant.

In some embodiments, the mapping type of the data bit sequence includes at least one of the following:

The first mapping type indicates that the amplitude of the modulation symbol is the 2 ^b amplitudes with the smallest amplitude (power) in the constellation diagram;

The second mapping type indicates that the amplitude of the modulation symbol is the 2 ^b amplitudes with the largest amplitude (power) in the constellation diagram;

The third mapping type indicates that the amplitude of the modulation symbol is the 2 ^b amplitudes in the constellation diagram that satisfy the maximum minimum difference between the amplitudes (power).

In the embodiments of the present disclosure, the name of the first mapping type is not limited, and its example is "minimum mapping (minMapping)". In the embodiments of the present disclosure, the name of the second mapping type is not limited, and its example is "maximum mapping (maxMapping)". In the embodiments of the present disclosure, the name of the third mapping type is not limited, and its example is "minimum maximization mapping (minMaxMapping)". The terms mapping type, amplitude modulation type, mapping mode, etc. are interchangeable.

Referring to FIG3A , taking 64QAM as an example, there are q(64)=9 different amplitudes. Assuming that 2 ² =4 amplitudes are selected from the q(64)=9 amplitudes to map every two data bits in a data bit sequence to one of the four amplitudes, FIG3B , FIG3C , and FIG3D illustrate the four amplitudes selected based on the first mapping type, the second mapping type, and the third mapping type, respectively.

In some embodiments, step S2101 is optional. When the terminal does not receive the first information sent by the network device, the terminal may map the data bit sequence into a symbol sequence based on a default value for the mapping type. Optionally, the default value for the mapping type may be predefined or configured by the network device. Optionally, the default value for the mapping type may be predefined in the protocol. Optionally, the network device may send third information to the terminal, the third information being used to configure the default value for the mapping type. Optionally, the terminal may autonomously determine the mapping type for the data bit sequence.

Step S2102: Map the data bit sequence into a symbol sequence according to the mapping type.

In some embodiments, the data bit sequence is a code block sequence after channel coding.

In some embodiments, the data bit sequence is mapped to a symbol sequence according to a mapping type, wherein symbols of different amplitudes in the symbol sequence correspond to b data bits in different states in the data bit sequence, and b is a positive integer.

In some embodiments, every b data bits in the data bit sequence are mapped to N _RF symbols according to a mapping type, the N _RF symbols have the same amplitude, and N _RF is a positive integer.

In some embodiments, the amplitudes of the _NRF symbols satisfy at least one of the following:

If the mapping type is the first mapping type, the amplitude of the N _RF symbols is one of the 2 ^b amplitudes with the smallest amplitude in the constellation diagram;

If the mapping type is the second mapping type, the amplitude of the N _RF symbols is one of the 2 ^b amplitudes with the largest amplitude in the constellation diagram;

If the mapping type is the third mapping type, the amplitude of the N _RF symbols is one of the 2 ^b amplitudes in the constellation diagram that satisfies the maximum minimum difference between amplitudes.

In some embodiments, the amplitudes of the N _RF symbols depend on a mapping relationship between b data bits and amplitudes. Optionally, the mapping relationship between b data bits and amplitudes may adopt Gray mapping to reduce a bit error rate (BER).

In some embodiments, each of the N _RF symbols is determined from constellation symbols of corresponding magnitude in a constellation diagram.

In some embodiments, the phase of each of the N _RF symbols is a random phase within [0, 2π).

Step S2103: The terminal sends a symbol sequence.

In some embodiments, the terminal sends the symbol sequence via a first waveform. Optionally, the first waveform is a CP-OFDM waveform.

In some embodiments, the network device receives a symbol sequence. Optionally, the network device receives a symbol sequence transmitted via a first waveform.

In some embodiments, the network device detects (equalizes) the received signal of the symbol sequence. The network device performs spatial domain filtering on the received signals of N _RF symbols with the same amplitude and carrying the same data bits, transforms the signals into the Khatri-Rao domain, and detects the equivalent transmitted signals of the N _RF symbols in the Khatri-Rao domain.

For ease of description, taking b data bits as an example, the transmission from the terminal to the network device can be expressed as the following formula:
y _i = _Hi x _i +n _i , i=1,…,N _RF

in, is the transmitted signal corresponding to the i-th symbol vector in N _RF symbol vectors, including N _t layers, N _t is the number of transmitting antennas of the terminal, and the average power of the signal transmitted by the terminal satisfies to Represents the power of N _RF symbol vectors at each layer, is the channel matrix of the uplink channel, N _r is the number of antenna elements in the sparse array used by the network device for reception; y _i , are the signal and noise of the corresponding i-th symbol vector received by the network device, and the average power of the noise received by the network device satisfies is the power of the noise, is the N _r ×N _r unit matrix.

Since the modulation mode is amplitude modulation, the amplitudes of the N _RF symbols are the same and they carry the same data bits. The network device performs spatial filtering on the N _RF received signal vectors (i.e., _yi ) and transforms the signal into the Khatri-Rao domain. Similarly, the filtered signal can be expressed as is the equivalent received signal in Khatri-Rao domain, is the equivalent channel matrix in Khatri-Rao domain, For the equivalent signaling in Khatri-Rao domain, is the equivalent noise in Khatri-Rao domain. Based on this, Detection. Compared with H _i , i＝1,…,N _RF , A larger number of rows (depending on the type and parameters of the sparse array of network equipment) can correspond to more virtual receive antennas in the Khatri-Rao domain. This obviously leads to greater diversity gain, thereby improving uplink coverage. Therefore, amplitude modulation can achieve greater diversity gain and higher reliability in the Khatri-Rao domain, thereby enhancing uplink coverage.

When performing amplitude modulation, in some embodiments, the mapping type is the first mapping type, which minimizes the total transmit power of the terminal to save power consumption. In some embodiments, the mapping type is the second mapping type, which maximizes the total transmit power of the terminal to avoid the receiving end (network device) being unable to receive the signal due to insufficient transmit power and further improve uplink coverage. In some embodiments, the mapping type is the third mapping type, which increases the amplitude interval of the modulation symbols to improve the reliability and accuracy of the receiving end's decision. The network device can dynamically indicate the mapping type, for example, instructing the terminal to use a certain mapping type based on the terminal's location in the network.

In some embodiments, the antenna array on the network device side is a sparse array, which can achieve the same effect as a uniform array using more antennas with fewer receiving antennas, thereby saving costs.
