[0003] In wireless mobile communication systems, because wireless channels are not fixed and predictable like wired channels but rather exhibit significant randomness, their performance is significantly affected by channel effects, such as shadow fading and frequency-selective fading. To accurately recover the transmitted signal at the receiver, the receiver typically uses channel equalization to compensate for channel fading. Channel equalization requires pre-acquisition of channel state information (CSI). Therefore, wireless mobile communication systems typically perform channel estimation by transmitting pilot symbols to obtain accurate CSI. Channel equalization then uses this CSI to eliminate channel-induced signal distortion.

[0027] To help those skilled in the art better understand the technical solutions of the embodiments of the present disclosure, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings of 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present disclosure without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0028] In the description of the present disclosure, unless otherwise specified, “ / ” means “or”. For example, A / B can mean A or B. “And / or” in this article is merely a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can mean: only A, A and B, and only B. In addition, “at least one” means one or more, and “a plurality” means two or more. Words such as “first” and “second” do not limit the quantity and execution order, and words such as “first” and “second” do not necessarily limit them to be different.

[0029] It should be noted that in this disclosure, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described in this disclosure as "exemplary" or "for example" should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0030] Currently, channel estimation methods commonly use algorithms such as the least squares method (LS) and the minimum mean square error (MMSE). Channel equalization typically employs algorithms such as zero forcing (ZF) and MMSE. Consequently, all algorithms based on non-blind channel estimation require the transmitter to send a pilot signal, generating pilot overhead and reducing the communication efficiency of wireless mobile communication systems.

[0031] The structure of a wireless transmission frame is shown in Figure 1. Each wireless frame consists of 10 subframes, and the number of time slots in each subframe is related to the subcarrier spacing setting. Each time slot includes 14 orthogonal frequency-division multiplexing (OFDM) symbols, and the transmitted pilot signal occupies resources on the corresponding OFDM symbol as needed. Therefore, the need to send pilot signals can lead to a decrease in communication efficiency.

[0032] In view of this, embodiments of the present disclosure provide a communication method, which includes, for example, sending a transmission frame, wherein the transmission frame includes data pilot symbols and data symbols. The data pilot symbols are used for channel estimation and carrying data information to be transmitted, while the data symbols are used to carry data information to be transmitted. This improves communication efficiency.

For example, the communication system can be a long term evolution (LTE) system, a fifth generation (5G) communication system, a Wi-Fi system, a communication system related to the third generation partnership project (3GPP), a future evolved communication system (such as a sixth generation (6G) communication system, etc.), or a system integrating multiple systems, etc., without limitation. The method provided by the embodiment of the present disclosure is described below using the communication system 100 shown in Figure 2 as an example.

[0037] In some embodiments, during a communication process, a network device sends data to a terminal device, and the terminal device receives the data sent by the network device.

[0038] It should be noted that Figure 2 is only an exemplary framework diagram. The number of devices or nodes included in Figure 2 and the names of each device are not restricted.

[0039] The application scenarios of the embodiments of the present disclosure are not limited.

Those skilled in the art will appreciate that with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present disclosure are equally applicable to similar technical problems.

[0040] The following describes the embodiments provided by the present disclosure in conjunction with the accompanying drawings.

[0041] As shown in FIG3 , an embodiment of the present disclosure provides a communication method, which includes the following steps: S101 , a transmitting end sends a transmission frame, which includes a data pilot symbol and a data symbol.

[0042] The data pilot symbol is used for channel estimation and carrying data information to be transmitted, and the data symbol is used for carrying data information to be transmitted.

[0043] In some embodiments, a transmission frame may include one or more time slots.

[0044] In one example, a transmission frame includes one time slot including data pilot symbols and data symbols.

[0045] In some embodiments, the number of symbols included in one time slot is greater than 1 and less than or equal to 15. Exemplarily, the number of data pilot symbols may be N, where N is less than the number of symbols in one time slot. slot The sending end can be N in this time slot. slot N symbols are randomly selected as data pilot symbols, and the remaining symbols except the data pilot symbols can be configured as data symbols. Thus, the number of data symbols can be (N slot -N). For example, as shown in FIG4 , the single-slot transmission frame includes a data pilot symbol 0 and data symbols 1-13.

[0046] In some embodiments, the transmitting end may introduce a cyclic prefix (CP) between each subcarrier to prevent inter-carrier-interference (ICI).

[0047] In other embodiments, the transmitting end may not introduce a cyclic prefix to implement CP-free communication transmission to improve transmission efficiency. As shown in Figure 5, in the case of CP-free transmission, the value of N can be 15, and the single-slot transmission frame includes data pilot symbol 0 and data symbols 1-14.

[0048] In another example, the transmission frame includes a plurality of time slots, and the plurality of time slots include at least one first time slot and at least one second time slot.

[0049] In some embodiments, the first time slot includes at least data pilot symbols. For example, the first time slot may include only data pilot symbols. Alternatively, the first time slot includes data pilot symbols and data symbols. Furthermore, the first time slot may also be referred to as a data pilot time slot.

[0050] In some embodiments, the second time slot includes only data symbols. In addition, the second time slot can also be called a data time slot.

[0051] In some embodiments, the number of symbols included in a time slot in the data frame is greater than 1 and less than or equal to 15. The total number of all data pilot symbols in the data frame may be N, where N is less than the number of symbols in the time slot N. slot A positive integer.

[0052] For example, as shown in FIG6 , the transmission frame includes time slot 1, time slot 2, and time slot 3. Time slot 1 includes data pilot symbol 0 and data symbols 1-13, and is the first time slot. All symbols 0-13 in time slot 2 are data symbols, and this time slot is the second time slot. Similarly, all symbols 0-13 in time slot 3 are data symbols, and this time slot is the second time slot.

[0053] It should be noted that based on the transmission frame structure including multiple time slots provided in the embodiment of the present disclosure, the transmission frame may include a second time slot without data pilot symbols, thereby reducing the generation and transmission of data pilot symbols, and further improving the transmission capacity and transmission efficiency of the wireless communication system.

[0054] In some embodiments, the transmitting end may perform coding and modulation processing, resource mapping processing, and symbol shaping processing on the data information to be transmitted to generate the above-mentioned data frame.

[0055] In some embodiments, for coding and modulation processing at the transmitter, data pilot symbols and data symbols within the same time slot are independently configured with a modulation and coding scheme (MCS). For example, for a single-slot data frame, the data pilot symbols and data symbols within the frame are independently configured with an MCS. For a data frame comprising multiple time slots, the data pilot symbols and data symbols within any first time slot of the frame are independently configured with an MCS. This allows for selecting an appropriate MCS configuration for each data pilot symbol or data symbol based on the actual usage environment, thereby achieving better transmission performance.

[0056] In some embodiments, all data symbols in the same time slot use the same MCS. Data symbols in different time slots are independently configured with an MCS. For example, using the single-slot transmission frame in FIG4 , the MCS for data pilot symbol 0 can be denoted as MCSp, and the MCSs for data symbols 1-13 can all be denoted as MCSd.

[0057] In some embodiments, different transport blocks (TBs) can also be independently configured with an MCS. In addition, data in different transport layers can also be independently configured with an MCS. For example, taking the transmission frame in Figure 6 as an example, the MCS of data pilot symbol 0 in time slot 1 can be expressed as MCSp, the MCS of data symbols 1-13 in time slot 1 can all be expressed as MCSd1, the MCS of data symbols 0-13 in time slot 2 can all be expressed as MCSd2, and the MCS of data symbols 0-13 in time slot 3 can all be expressed as MCSd3.

[0058] In some embodiments, the data pilot symbol supports at least one of the following modulation schemes: quadrature phase shift keying (QPSK), 16QAM (quadrature amplitude modulation), 64QAM, and 256QAM.

[0059] In some embodiments, the data information to be transmitted may include first data to be transmitted and second data to be transmitted. The transmitting end may generate a data pilot symbol based on the first data to be transmitted, and generate a data symbol based on the second data to be transmitted.

[0060] Exemplarily, the transmitting end may perform coding modulation, resource mapping, and symbol shaping on the first data to be transmitted to generate data pilot symbols. Furthermore, the transmitting end may perform coding modulation, resource mapping, and symbol shaping on the second data to be transmitted to generate data symbols.

[0061] In an example, as shown in FIG7 , the process of generating a data frame at the transmitting end based on the data to be transmitted can be implemented as the following S1 to S3.

[0062] In S1, the transmitting end performs coding and modulation on the data information to be transmitted to obtain modulation symbols.

[0063] In some embodiments, the transmitting end may first determine the data pilot symbol and the number of transmission information bits of the data symbol based on the number of resource blocks (RBs) scheduled for transmission, the number of spatial streams, and the MCS index value, and then generate the pilot data symbol transmission bit information according to the number of transmission information bits of the data pilot symbol and the above-mentioned data information to be transmitted, that is, the first data to be transmitted, and generate the data symbol transmission bit information according to the number of transmission information bits of the data symbol and the above-mentioned data information to be transmitted, that is, the second data to be transmitted.

[0064] Thus, the transmitting end can perform channel coding on the data to be transmitted to obtain coded bit data. The channel coding method can adopt methods such as low density parity check code (LDPC) and Polar coding.

[0065] In some embodiments, the data pilot symbol includes a first pilot symbol and a second pilot symbol. The transmitting end may generate a first modulation symbol based on the first data to be transmitted, and generate a second modulation symbol based on the second data to be transmitted.

[0066] In one example, taking the communication system 100 as an example, the data frame in the communication system 100 adopts a single-slot transmission frame format. The number of data streams is 1, the number of antenna ports is 1, and the number of physical transmit antennas and physical receive antennas is 1. The number of symbols N contained in the single-slot transmission frame is slot = 14, the number of data pilot symbols N = 1. Furthermore, the data pilot symbols and data symbols are encoded independently.

[0067] The MCS used by the data pilot symbol is MCSp=10. The transmitting end can first obtain the coded data X based on the first data to be transmitted. p Then, based on the modulation order of MCSp=10, Q is configured. m,pw =4 pairs of X p Perform modulation processing to obtain the first modulation symbol Y after modulation processing p , Y p =Modulate(X p ,4).

[0068] The MCS used by the data symbol is MCSd=19. The transmitting end can obtain the encoded data X based on the second data to be transmitted. d Then, based on the modulation order configuration of MCSd=19, Q m,da =6 pairs of X d Perform modulation processing to obtain the second modulation symbol Y after modulation processing d , Y d =Modulate(X d ,6).

[0069] In another example, taking the communication system 100 as an example, the data frame in the communication system 100 adopts a transmission frame format of 3 time slots. The number of data streams is 2, the number of antenna ports is 2, and the number of physical transmit antennas and physical receive antennas is 2. A transmission frame includes 1 first time slot and 2 second time slots. The number of symbols contained in the first time slot is N. slot =14, the number of data pilot symbols N=1, and the number of symbols contained in the second time slot is also 14.

[0070] In the communication system 100, data pilot symbols and data symbols are independently configured with MCSs, and all data symbols in the same time slot use the same MCS, while data symbols in different time slots are independently configured with MCSs.

[0071] For the first time slot, the MCS used by the data pilot symbol is MCSp=0. The transmitting end can first obtain the coded data X based on the first data to be transmitted. p Then, based on the modulation order configuration Q corresponding to MCSp = 0 m,pw =2, for X p Perform modulation processing to obtain the first modulation symbol Y after modulation processing p , Y p =Modulate(X p ,2).

[0072] The MCS used by the data symbol in the first time slot is MCSd1=10. The transmitting end can obtain the encoded data X based on the portion of the second data to be transmitted corresponding to the data symbol. d1 Then, based on the modulation order configuration of MCSd1=10, Q m,da1 =4, for X d Perform modulation processing to obtain the modulation symbol Y after modulation processing d1 , Y d1 =Modulate(X d1 ,4).

[0073] For the two second time slots in the transmission frame, the transmitting end can obtain the encoded data X based on the part of the second data to be transmitted corresponding to the data symbols of each second time slot. d2 、X d3 Then, modulation processing is performed based on MCSd2=19 configured in one second time slot and MCSd3=27 configured in another second time slot. The modulation order configuration corresponding to MCSd2=19 is Q m,da2 =6, and the modulation symbol Y after modulation processing is obtained d2 , Y d2 =Modulate(X d2 ,6). The modulation order configuration corresponding to MCSd3=27 is Q m,da3 =8, and the modulation symbol Y after modulation processing is obtained d3 , Y d3 =Modulate(X d3 ,8).

[0074] In another example, taking the communication system 100 as an example, the data frame in the communication system 100 adopts a single-slot transmission frame format. The number of data streams is 4, the number of antenna ports is 4, and the number of physical transmit antennas and physical receive antennas is 4. A CP-free transmission mode is used, and the number of symbols contained in the time slot is N. slot =15, the number of data pilot symbols N=1, and the number of symbols contained in the second time slot is also 14.

[0075] In the communication system 100, data pilot symbols and data symbols are independently configured with MCSs, and data pilot symbols are also independently configured with MCSs in different transmission layers.

[0076] For the data pilot symbol, the data stream of the communication system 100 is 4, that is, the number of transmission layers is 4, and the MCS used by the data pilot symbol in each transmission layer includes MCSp1=0, MCSp2=0, MCSp3=10, and MCSp4=10. The transmitting end can first obtain the data X of each transmission layer after encoding based on the first data to be transmitted. p =[X p1 ,X p2 ,X p3 ,X p4 ]. Furthermore, based on the modulation order configuration corresponding to MCSp1=0, MCSp2=0, MCSp3=10, and MCSp4=10, [Q m,pw1 =2,Q m,pw2 =2,Q m,pw3 =4,Q m,pw4 =4], respectively for X p1 ,X p2 ,X p3 ,Xp4 Perform modulation processing to obtain the first modulation symbol Y after modulation processing p , Y p =[Y p1 ,Y p2 ,Y p3 ,Y p4 ],Y p1 =Modulate(X p1 ,2),Y p2 =Modulate(X p2 ,2),Y p3 =Modulate(X p3 ,4),Y p4 =Modulate(X p4 ,4).

[0077] The MCS used by the data symbol is MCSd=19. The transmitting end can obtain the encoded data X based on the second data to be transmitted. d Then, based on the modulation order configuration of MCSd=19, Q m,da =6, for X d Perform modulation processing to obtain the second modulation symbol Y after modulation processing d , Y d =Modulate(X d ,6).

[0078] In S2, the transmitter performs resource mapping on the modulation symbols to obtain frequency domain data.

[0079] In some embodiments, the transmitter may use N transmission layers to perform layer mapping on the modulation symbols to obtain frequency domain data. N is a positive integer. For example, the value of N may be 1, 2, 4, or other possible values.

[0080] Layer mapping involves mapping modulation symbols to different transport layers (new data streams). A transport layer is a transmission channel, and the number of layers in a transport layer represents the number of transmission channels used simultaneously. For example, if the number of layers is two, two transmission channels transmit information simultaneously. The information transmitted by two transport layers at the same time can be the same or different, without limitation here. Furthermore, frequency domain data includes modulation symbols at various locations within each transport layer of one or more transport layers.

[0081] It should be noted that because the number of codewords for the data to be transmitted is inconsistent with the number of transmit antennas, the data to be transmitted needs to be mapped to different transmit antennas, so layer mapping is required. The transmitter can first use layer mapping to remap the first modulation symbol to multiple layers (new data streams) based on certain rules, and then map the data to the antenna ports through processing.

[0082] In some embodiments, the frequency domain data may include first frequency domain data and second frequency domain data. The transmitting end may perform resource mapping on the first modulation symbol to obtain the first frequency domain data.

[0083] In some embodiments, the first frequency domain data is used to indicate a frequency domain mapping position of the data pilot symbol. In some embodiments, the frequency domain mapping position is determined based on the transmission layer where the data pilot symbol is located, the number of transmission layers, and the number of resource blocks (RBs).

[0084] Exemplarily, the frequency domain mapping position k of the data pilot symbol is determined based on the following formula (1): k=L·n+p Formula (1)

[0085] And, n=0, 1, ... (12*RB Num / L-1), p=0, 1,..., L-1.

[0086] In the above formula, k represents the subcarrier index of the frequency domain mapping position, p represents the index of the transmission layer where the data pilot symbol is located, L represents the total number of transmission layers, RB Num Indicates the total number of scheduled RBs.

[0087] In some embodiments, when the number of transmission layers for resource mapping is one, the first frequency domain data is mapped to one transmission layer, and the data in the transmission layer occupies multiple subcarriers of the data pilot symbol.

[0088] In other embodiments, when there are multiple transmission layers for resource mapping, the first frequency-domain data is mapped to the multiple transmission layers, and the data in different transmission layers of the multiple transmission layers occupy different subcarriers of the data pilot symbols. For example, the transmitting end may periodically allocate the first frequency-domain data to multiple consecutive subcarriers of the data pilot symbols, using the number of transmission layers as an allocation period. One allocation period includes data from each transmission layer in all transmission layers.

[0089] For example, when N=1, the transmitting end may modulate the first modulation symbol Y p Map to the transmission layer to obtain the first frequency domain data For example, as shown in FIG8A , the transmitting end may p Mapped to transmission layer a1, and the transmission layer a1 occupies subcarriers 0-11 of the data pilot symbol.

[0090] Alternatively, in the case of N=2, the transmitting end may use the first modulation symbol Y p Mapped to two transmission layers. Thus, the first frequency domain data obtained includes the first transmission layer corresponding And the corresponding second transport layer

[0091] Exemplarily, as shown in FIG8B , the subcarriers occupied by the data of the transmission layer b1 (first transmission layer) include subcarriers 0, 2, 4, 6, 8, and 10, and the subcarriers occupied by the data of the transmission layer b2 (second transmission layer) include subcarriers 1, 3, 5, 7, 9, and 11. The transmitting end uses the number of transmission layers 2 as the allocation period and periodically allocates the first frequency domain data to a plurality of consecutive subcarriers 0-11 of the data pilot symbol. For example, the subcarriers of one allocation period may include subcarriers 0 and 1, 2 and 3, etc. Taking subcarriers 0 and 1 as an example, the data of the transmission layer b1 may occupy subcarrier 0, and the data of the transmission layer b2 may occupy subcarrier 1.

[0092] Alternatively, when N=4, the transmitter may use the first modulation symbol Y p Mapped to four transmission layers. Thus, the first frequency domain data obtained includes the first transmission layer corresponding The second transport layer corresponds to The third transport layer corresponds to And the corresponding fourth transport layer

[0093] For example, as shown in FIG8C , the subcarriers occupied by the data of transmission layer c1 (first transmission layer) include subcarriers 0, 4, and 8, the subcarriers occupied by the data of transmission layer c2 (second transmission layer) include subcarriers 1, 5, and 9, the subcarriers occupied by the data of transmission layer c3 (third transmission layer) include subcarriers 2, 6, and 10, and the subcarriers occupied by the data of transmission layer c4 (fourth transmission layer) include subcarriers 3, 7, and 11. The transmitting end uses the number of transmission layers 4 as an allocation period and periodically allocates the first frequency domain data to a plurality of consecutive subcarriers 0-11 of the data pilot symbol. For example, the subcarriers of one allocation period may include subcarriers 0-3, 4-7, and so on. Taking subcarriers 0-3 as an example, the data of transmission layer c1 may occupy subcarrier 0, the data of transmission layer c2 may occupy subcarrier 1, the data of transmission layer c3 may occupy subcarrier 2, and the data of transmission layer c4 may occupy subcarrier 3.

[0094] In some embodiments, the transmitting end may further perform resource mapping on the second modulation symbol to obtain second frequency domain data.

[0095] In some embodiments, data in multiple transmission layers (data streams) in the second frequency domain data may be superimposed.

[0096] For example, when N=1, the transmitting end may use the second modulation symbol Y d Mapped to the transmission layer, the second frequency domain data obtained is For example, as shown in FIG8A , the transmitting end mayd Mapped to the data pilot symbol transmission layer a2, and the transmission layer a2 occupies subcarriers 0-11 of the data symbol.

[0097] Alternatively, in the case of N=2, the transmitter may use the second modulation symbol Y d Mapped to two transmission layers.
