As long as the same technical effect is achieved, the base station is not limited to specific technical vocabulary. It should be noted that in the embodiments of the present application, only the base station in the NR system is used as an example for introduction, and the specific type of the base station is not limited.

[0050] The core network equipment may include but is not limited to at least one of the following: core network node, core network function, mobility management entity (Mobility Management Entity, MME), access mobility management function (Access and Mobility Management Function, AMF), session management function (Session Management Function, SMF), user plane function (User Plane Function, UPF), policy control function (Policy Control Function, PCF), policy and charging rules function unit (Policy and Charging Rules Function, PCRF), edge application service discovery function (Edge Application Server Discovery Function, EASDF), unified data management (Unified Data Management, UDM), unified data storage (Unified Data Repository, UDR), home user server (Home Subscriber Server, HSS), centralized network configuration (CNC), network storage function (Network Repository Function, NRF), network exposure function (Network Exposure Function, NEF), local NEF (Local NEF, or L-NEF), binding support function (Binding Support Function, BSF), application function (Application Function, AF), etc. It should be noted that in the embodiments of the present application, only the core network device in the NR system is introduced as an example, and the specific type of the core network device is not limited.

[0051] In some embodiments, the terminal and the network side device can refer to Figure 2 As shown, the terminal includes a main communication module and an extremely low power consumption communication module, and the network side device includes a main communication module and an extremely low power consumption communication module. The main communication module and the extremely low power consumption communication module can communicate with each other, and the extremely low power consumption communication module of the terminal can communicate with the extremely low power consumption communication module of the network side device. It should be noted that Figure 2 This is just an example. For example, in some embodiments, the main communication module of the terminal can communicate with the main communication module of the network side device. In some embodiments, the ultra-low power consumption communication module of the terminal can communicate with the main communication module of the network side device.

[0052] In some embodiments, the main communication module can support traditional communication modes (such as 4G, 5G, 6G, etc.) and communication technologies for mobile broadband (MBB) or enhanced mobile broadband (eMBB) scenarios; for example: 5G NR technology that supports orthogonal frequency division multiplex (OFDM) communication, including uplink and / or downlink communication.

[0053] In some embodiments, the extremely low power communication module can support extremely low power communication (such as supporting sending signals by backscatter) or support low power reception, for example: the extremely low power communication module includes a low power receiving module, such as a low power wake-up receiver. For sending signals by backscatter, the excitation source signal can be generated by the terminal with the extremely low power communication module itself or by other devices. For example: in the case where the above-mentioned extremely low power communication module is a backscatter communication module, the main communication module will naturally excite the extremely low power communication module when sending signals, so the additional backscatter signal generated has almost no additional overhead.

[0054] In some embodiments, the extremely low power communication may include at least one of the following:

[0055] Supports backscatter communication for energy harvesting;

[0056] Support powered backscatter communications;

[0057] Low power reception.

[0058] For example: Ultra-low power communication modules can support energy harvesting, including but not limited to harvesting energy from light, solar energy, wireless signals, etc.

[0059] In addition, the excitation source signal of the backscatter communication may be generated by the terminal itself with the extremely low power consumption communication module or by other devices.

[0060] In some embodiments, extremely low power communication may refer to communication whose power consumption is significantly lower than that of the main communication module. For example, communication of a communication module whose power consumption is generally tens of microwatts to hundreds of microwatts is extremely low power communication, while the power consumption of the main communication module is generally tens of milliwatts to thousands of milliwatts, and the cost of the extremely low power communication module is also significantly lower than that of the main communication module.

[0061] Backscatter communication is the most representative technology for ultra-low power communication. In principle, backscatter communication equipment controls the reflection coefficient of the circuit by adjusting its internal impedance, thereby changing the amplitude, frequency, phase, etc. of the RF signal from other devices or the environment to achieve signal modulation. Typical backscatter communication hardware modules can be as follows: Figure 3 As shown, it includes: antenna unit, energy collection module or energy supply module, microcontroller, signal receiving module, channel coding and modulation module, memory or sensor module, etc. Among them, the signal receiving module is responsible for receiving the downlink signal sent to the backscattering device by the network side device or card reader, etc. Its architecture and technology can reuse the low-power wake-up receiver technology defined in the protocol or newly defined in the future; since the backscattering communication does not actively generate radio frequency signals, its energy consumption is extremely low, usually between tens of microwatts and hundreds of microwatts, and the energy collection module can collect energy such as radio frequency signals, light energy, thermal energy, etc. in the environment to modulate, demodulate and reflect the signal, without having its own energy source such as batteries; it can also be supplied by small energy supply modules such as button batteries, thereby reducing the strength requirements of the energy supply signal. In addition to the above typical components, the backscattering communication technology can integrate low-power amplifier modules to improve the receiving sensitivity and backscattering signal power.

[0062] It should be noted that in the embodiments of the present application, backscatter communication is only an example of extremely low power consumption communication. In the embodiments of the present application, there is no limitation on extremely low power consumption communication. For example, it may be extremely low power consumption communication defined in the protocol, such as communication of a communication module with power consumption ranging from tens of microwatts to hundreds of microwatts.

[0063] In combination with the accompanying drawings, a data transmission method, a data receiving method, an apparatus and a device provided by an embodiment of the present application are described in detail below through some embodiments and their application scenarios.

[0064] See also Figure 4 , Figure 4 is a flow chart of a data transmission method provided in an embodiment of the present application, such as Figure 4 As shown, the following steps are included:

[0065] Step 401: A first device performs parallel transmission through a first communication module and a second communication module, wherein the parallel transmission includes:

[0066] Repeated, multiplexed or mixed transmissions;

[0067] Wherein, in the repeated transmission, the data transmitted by the first communication module and the data transmitted by the second communication module are the same data;

[0068] In the multiplex transmission, the data transmitted by the first communication module and the data transmitted by the second communication module are different data;

[0069] In the mixed transmission, the data transmitted through the first communication module and the data transmitted through the second communication module include the same data, and the data transmitted through the first communication module and the data transmitted through the second communication module also include different data.

[0070] The first device may be a terminal or a network side device.

[0071] In some embodiments, the first communication module may be one of an extremely low power communication module and a main communication module, and the second communication module may be the other of the extremely low power communication module and the main communication module. For example, the first communication module is the main communication module, and the second communication module is the extremely low power communication module, or the second communication module is the main communication module, and the first communication module is the extremely low power communication module. The extremely low power communication module is a module that supports extremely low power communication, and the power consumption of the main communication module is higher than that of the extremely low power communication module.

[0072] In some embodiments, the first communication module and the second communication module are two different extremely low power consumption communication modules. For example, the first communication module and the second communication module are communication modules that can send signals in the form of backscattering and actively generate carrier waves. For example, the first device is an IoT terminal with two communication modes, such as an IoT terminal that can send signals in the form of backscattering and actively generate carrier waves.

[0073] In some implementations, the first communication module and the second communication module may be two completely independent communication modules, or the first communication module and the second communication module may share part or all of the module contents.

[0074] The above-mentioned parallel transmission by the first device through the first communication module and the second communication module may be that the first device sends data to the second device through the first communication module and the second communication module at the same time.

[0075] The above-mentioned repeated transmission may mean that the information transmitted by the two communication modules is the same data in the physical channel or logical channel, such as the data transmitted by the first communication module and the data transmitted by the second communication module are the same data in the same transmission block (Transport Block, TB), which is used to increase the reliability of transmission.

[0076] In the embodiment of the present application, if the TB is long, the TB can be divided into multiple code blocks (Codeblock, CB). Therefore, the TB in the embodiment of the present application can be a CB, or an undivided TB.

[0077] The above-mentioned multiplexing refers to transmitting multiple different data through two communication modules. For example, in the case of the multiplexing, the data transmitted through the first communication module and the data transmitted through the second communication module are different data in the same TB, or the data transmitted through the first communication module and the data transmitted through the second communication module are data in different TBs, thereby improving the transmission performance of the communication device.

[0078] The above-mentioned mixed transmission refers to transmitting the same data and transmitting different data through two communication modules, thereby improving the transmission performance of the communication device.

[0079] In an embodiment of the present application, the above steps can realize parallel transmission through two communication modules, thereby improving the transmission performance of the communication device. For example, the reliability of the communication device transmission can be improved through repeated transmission, the transmission rate of the communication device can be improved through multiplex transmission, and the reliability and rate of the communication device transmission can be improved through mixed transmission.

[0080] As an optional implementation manner, when the parallel transmission includes the repeated transmission or the mixed transmission, at least one of the following data processing processes of the data transmitted by the first communication module and the data transmitted by the second communication module is the same:

[0081] Add cyclic redundancy check (CRC);

[0082] Channel coding;

[0083] Rate matching;

[0084] Hybrid Automatic Repeat Request (HARQ) Redundancy Version (RV Generation).

[0085] The adding of CRC mentioned above may be adding CRC to TB to verify the correctness of TB.

[0086] The above-mentioned channel coding may be channel coding of TB+CRC according to the code rate indicated by the modulation and coding scheme (MCS), such as low density parity check (LDPC), polar code, etc. The bits after channel coding may include two types: systematic bits and parity check bits. Among them, the systematic bits are the original bits to be transmitted (including the CRC bits of the TB), and the parity bits are redundant bits used to recover the systematic bits. Generally speaking, the importance of the systematic bits is higher than that of the parity bits.

[0087] The above-mentioned rate matching can be processing the data obtained through channel coding, on the one hand to finally meet the code rate requirements of MCS, and on the other hand to meet the number of available physical resources. The rate matching can include at least one of the following: puncturing, shortening, lengthening, etc.

[0088] The above HARQ RV generation may be that the rate-matched data is placed in a ring buffer, such as Figure 5 As shown, the cache has 4 starting bit positions, corresponding to 4 HARQ RVs respectively. During transmission, according to the required transmission RV version number, a specified number of bits are read from the corresponding position.

[0089] In this implementation manner, since at least one of the processes of adding CRC, channel coding, rate matching, and HARQ RV generation is the same, device overhead can be saved.

[0090] Optionally, the method further includes:

[0091] Channel coding the data to which the CRC is added according to the first MCS or the third MCS to obtain coded data;

[0092] The first device performs parallel transmission through the first communication module and the second communication module, including:

[0093] performing data transmission processing on the coded data according to the first MCS through the first communication module;

[0094] The encoded data is processed for data transmission according to a second MCS through the second communication module.

[0095] The first MCS is the MCS used by the first communication module, and the third MCS is an MCS other than the MCS used by the first communication module and the second communication module, which may be specifically determined by the first device or indicated by the second device.

[0096] The channel coding of the data with CRC added by the first MCS or the third MCS may be implemented by the first communication module or by a structure other than the first communication module and the second communication module, which is not limited.

[0097] The rate matching code rates and the adopted modulation orders of the first MCS and the second MCS may be different or the same.

[0098] The data transmission processing of the coded data according to the first MCS is the sending processing of the coded data according to the first MCS, and the data transmission processing of the coded data according to the second MCS is the sending processing of the coded data according to the second MCS.

[0099] Optionally, the performing data transmission processing on the coded data according to the second MCS includes:

[0100] Keep all data or select some of it.

[0101] Among them, retaining all data or selecting part of the data can be understood as performing rate matching according to the second MCS, such as selectively discarding data after channel coding, such as mainly retaining system bits, thereby reducing the number of bits actually required to be sent.

[0102] In this way, by retaining all the data or selecting part of the data, the transmission rate of the second communication module can be matched to improve the transmission performance of the second communication module.

[0103] For example: Figure 6 As shown, after channel coding, the two modules respectively perform rate matching, HARQ RV generation and interleaving on the encoded data according to the indicated first MCS (MCS1 in the figure) and second MCS (MCS2 in the figure). The rate matching of the second communication device also assumes the function of bit selection, and selectively retains or discards the data after channel coding. For example, mainly retains the system bits. Since the original code rate of the channel coding needs to be the same, only one MCS is needed to determine the code rate of the channel coding; and the rate matching code rate (and specific operation) and the modulation order adopted by the two modules can be different. In some embodiments, the two modules can generate their own HARQ RV processes completely independently.

[0104] In the above implementation, it is possible to share the channel coding process during repeated transmission, thereby saving equipment overhead.

[0105] Optionally, the method further includes:

[0106] Channel coding and rate matching are performed on the data to which the CRC is added according to the first MCS or the third MCS, and HARQ RV generation processing is performed to obtain HARQ RV data; or channel coding is performed on the data to which the CRC is added according to the first MCS or the third MCS, and HARQ RV generation processing is performed to obtain HARQ RV data;

[0107] The first device performs parallel transmission through the first communication module and the second communication module, including:

[0108] performing data transmission processing on the HARQ RV data according to the first MCS through the first communication module;

[0109] The HARQ RV data is processed for data transmission according to the second MCS through the second communication module.

[0110] In some implementations, when the HARQ RV data is generated and rate matched, the data transmission processing of the HARQ RV data according to the second MCS includes retaining all data or selecting part of the data. For example, the data transmission processing of the HARQ RV data according to the second MCS includes retaining all data or discarding selected part of the data. This process may be referred to as rate matching, so that the number of bits processed by the second communication module matches the transmission rate.

[0111] In some implementations, when rate matching is not performed before the HARQ RV data is generated, performing data transmission processing on the HARQ RV data according to the first MCS includes rate matching, and performing data transmission processing on the HARQ RV data according to the second MCS includes rate matching.

[0112] For example: Figure 7 As shown, when generating HARQ RV, it is first generated according to the requirements of the first communication module, including rate matching, and then the generated HARQ RV data is submitted to the second communication module for bit selection. At this time, the bit selection needs to be adjusted according to the code rate of the second MCS (MCS2 in the figure) indicated by the second communication module. The purpose is to match the number of bits with the transmission rate, and then modulate according to the modulation order of the second MCS.

[0113] In the above implementation, it is possible to share channel coding, rate matching and HARQ RV generation process during repeated transmission, or it is possible to share channel coding and HARQ RV generation process during repeated transmission, thereby saving device overhead.

[0114] Optionally, the method further includes:

[0115] Channel coding is performed on the data to which the CRC is added to obtain coded data, wherein a code rate of the channel coding corresponds to a channel coding code rate corresponding to the first MCS and the second MCS respectively, and the channel coding code rates corresponding to the first MCS and the second MCS are the same;

[0116] Performing HARQ RV generation processing on the coded data to obtain HARQ RV data;

[0117] The first device performs parallel transmission through the first communication module and the second communication module, including:

[0118] Performing data transmission processing on the HARQ RV data according to the first MCS through the first communication module, wherein the data transmission processing on the HARQ RV data according to the first MCS includes rate matching;

[0119] The second communication module performs data transmission processing on the HARQ RV data according to the second MCS, and the data transmission processing on the HARQ RV data according to the second MCS includes rate matching.

[0120] The code rates of the channel coding correspond to the channel coding code rates corresponding to the first MCS and the second MCS respectively, which can be understood as the code rates of the channel coding in the first MCS and the second MCS being the same.

[0121] In this implementation, the data transmission processing includes rate matching, which can be implemented by performing rate matching on the HARQ RV data so that the number of bits processed by the first communication module and the second communication module matches the number of bits that can actually be transmitted.

[0122] Optionally, performing data transmission processing on the HARQ RV data according to the second MCS includes:

[0123] Keep all data or select some of it.

[0124] For example, the rate matching performed by the second communication module may include: retaining all data or selecting part of the data.

[0125] The above-mentioned retaining all data or selecting part of the data may be selectively retaining or discarding the HARQ RV data, such as mainly retaining system bits so that the number of bits matches the transmission rate.

[0126] For example: Figure 8 As shown, rate matching can be placed after generating HARQ RV. For example, the first device first needs to divide the TB to generate multiple HARQ RVs, and then submit them to the first communication module and the second communication module for rate matching and modulation respectively to obtain the final signals sent by each.

[0127] In the above implementation, it is possible to share the channel coding and HARQ RV generation process during repeated transmission, thereby saving equipment overhead.

[0128] As an optional implementation, the method further includes:

[0129] Channel coding is performed on the data to which the CRC is added to obtain coded data, wherein a code rate of the channel coding corresponds to a channel coding code rate corresponding to the first MCS and the second MCS respectively, and the channel coding code rates corresponding to the first MCS and the second MCS are the same;

[0130] Performing HARQ RV generation processing on the coded data to obtain HARQ RV data;

[0131] In the case where the parallel transmission includes the multiplex transmission, the first device performs parallel transmission through the first communication module and the second communication module, including:

[0132] Performing data transmission processing on a first part of the HARQ RV data according to the first MCS through the first communication module, wherein the data transmission processing on the HARQ RV data according to the first MCS includes rate matching;

[0133] Through the second communication module, data transmission processing is performed on a second part of the HARQ RV data according to a second MCS, and the data transmission processing performed on the HARQ RV data according to the second MCS includes rate matching.

[0134] The first part of data and the second part of data belong to the same HARQ RV; or the first part of data and the second part of data include data in different HARQ RVs.

[0135] The above-mentioned first part of data and the second part of data include data in different HARQ RVs, which may be that the first part of data and the second part of data are data from different HARQ RVs respectively, or the first part of data and the second part of data include data in the same HARQ RV, and the first part of data or the second part of data also includes data in different HARQ RVs.

[0136] For example, the first part of the data can be called RV Part I, and the second part of the data can be called RV Part II. Fig. 9 As shown, after the HARQ RV is generated, the data will be divided into two parts (RV Part I and RV Part II), RV Part I enters the first communication module for transmission, and RV Part II enters the second communication module for transmission, and the MCS of the two may be different. In the case where Part I and Part II together constitute a HARQ RV, in the initial transmission, the receiving end needs to obtain both parts completely to decode, but if it is not the initial transmission, the receiving end only obtains Part I or Part II, which can also be used for decoding.

[0137] In this implementation, a HARQ RV may be divided into more parts, thereby taking advantage of the fact that the transmission times of two communication modules may be unequal. While waiting for one communication module to complete the transmission of one RVPart, another communication module may send a different RV Part to improve transmission performance.

[0138] In addition, the RV Parts transmitted by the two modules can also come from different RVs, which is equivalent to transmitting the next RV in advance to improve the transmission performance.

[0139] As an optional implementation manner, when the parallel transmission includes the mixed transmission, the first device performs parallel transmission through the first communication module and the second communication module, including:

[0140] Data from the first TB is repeatedly transmitted through the first communication module and the second communication module, and multiplexed through the first communication module and the second communication module.

[0141] In this implementation, it is possible to implement repeated transmission of the same TB of data in mixed transmission, and also to implement multi-path transmission through the first communication module and the second communication module, so as to improve the transmission performance of the communication device.

[0142] Optionally, in performing multiplexing through the first communication module and the second communication module:

[0143] The data transmitted by the first communication module and the second communication module are from the same HARQ RV of the first TB; or,

[0144] The data transmitted by the first communication module and the second communication module come from different HARQ RVs of the first TB; or,

[0145] The data transmitted by the first communication module and the second communication module come from the second TB and the third TB respectively.

[0146] In this implementation, multiplexing of the same HARQ RV of the same TB, multiplexing of different HARQ RVs of the same TB, or multiplexing of data of different TBs can be implemented in mixed transmission to improve the transmission performance of the communication device.

[0147] Optionally, when the data transmitted by the first communication module and the second communication module are respectively from the second TB and the third TB, the repeatedly transmitting the data from the first transmission block TB by the first communication module and the second communication module, and performing multiplexing by the first communication module and the second communication module include:

[0148] Channel coding the data added with CRC from the first TB according to the first MCS, and performing HARQ RV generation processing to obtain first HARQ RV data; channel coding the data added with CRC from the second TB according to the first MCS, and performing HARQ RV generation processing to obtain second HARQ RV data; channel coding the data added with CRC from the third TB according to the second MCS, and performing HARQ RV generation processing to obtain third HARQ RV data;

[0149] concatenating a first portion of the first HARQ RV data with the second HARQ RV data to obtain first concatenated data, and performing data transmission processing on the first concatenated data according to the first MCS through the first communication module;

[0150] The second part of the data in the first HARQ RV data is concatenated with the third HARQ RV data to obtain second concatenated data, and data transmission processing is performed on the second concatenated data according to the second MCS through the second communication module.

[0151] Among them, the generation of the above-mentioned first HARQ RV data and the second HARQ RV data can be completed by the first communication module, or not by the first communication module, and the above-mentioned third HARQ RV data can be completed by the second communication module, or not by the second communication module, and there is no limitation on this.

[0152] The above data transmission processing includes rate matching, modulation and other processing.

[0153] For example: the independent data parts of two communication modules come from different TBs, such as Fig.10 As shown, the MAC layer submits three TBs, and the first communication module and the second communication module repeatedly transmit TB1, and transmit TB2 and TB3 respectively. Assume that the channel coding rate of TB2 and TB1 is controlled by MCS1, and the channel coding rate of TB3 is controlled by MCS2, and the code rate and modulation order of the final transmission of the two communication modules are controlled by MCS1 and MCS2 respectively.

[0154] In this implementation, different TBs of data can be concatenated, so that the first communication device and the second communication device can transmit different TBs of data together, thereby improving transmission performance.

[0155] As an optional implementation manner, the first MCS and the second MCS belong to different MCS tables respectively.

[0156] The first MCS and the second MCS respectively belong to different MCS tables, which may be that the first device is configured with multiple MCS tables, wherein one MCS table is used for the first communication module and the other MCS table is used for the second communication module. In this way, the MCS table can be simplified to reduce the complexity of the device. Alternatively, it can be understood that the MCS tables used by the first communication module and the second communication module are independently configured. For example, when the device has an MCS table corresponding to the first communication module, there is no need to change the configuration of the MCS table corresponding to the first communication module, and it is only necessary to configure the MCS table corresponding to the second communication module for the device (addition), thereby reducing the configuration overhead.

[0157] In some implementations, the MCS table of the second communication module added by the first device may be as shown in Table 1 below:

[0158] Table 1:

[0159]

[0160] The modulation order indicates the number of bits that a symbol can carry, which is a positive integer value.

[0161] Modulation mode (optional) indicates the way in which symbols carry bits, such as Amplitude Shift Keying (ASK), Phase Shift Keying (PSK), Quadrature Amplitude Modulation (QAM), etc. For example, 00 represents ASK, 01 represents PSK, and 10 represents QAM, etc.

[0162] Code rate representation: If it is assumed that the code rate of the channel coding is determined by another MCS, then the code rate here refers to the rate matching code rate, which is a value in the range of 0-1;

[0163] The bit selection method indicates how to obtain a second target HARQ RV from a generated HARQ RV. For example, 0 indicates taking one bit from X equally spaced bits of the HARQ RV; 1 indicates reserving the system bit of the HARQ RV; and so on.

[0164] The spectrum efficiency is determined by the above parameters and represents the spectrum efficiency that can be obtained for an MCS, which is a value between 0 and 1.

[0165] The first MCS and the second MCS respectively belong to different MCS tables, which means that the first device is configured with multiple MCS tables, wherein one MCS table is used by the first communication module and the other MCS table is used by the second communication module.

[0166] The above-mentioned multiple MCS tables may be multiple MCS tables configured by the first device receiving the network side, or agreed upon by the protocol.

[0167] As an optional implementation, the first MCS and the second MCS belong to the same MCS table, and the first index in the MCS table corresponds to two groups of MSC parameters; the channel coding code rates corresponding to the two groups of MCS parameters are the same.

[0168] The first MCS and the second MCS belong to the same MCS table, which can be an MCS table configured by the first device and can be used by both the first communication module and the second communication module. The MCS table can be received by the first device from the network side, or agreed upon by the protocol.

[0169] The first index in the MCS table corresponds to two groups of MSC parameters, which can be understood as two groups of MCS parameters can be determined by the first index in the MCS table. For example, each index in the MCS table corresponds to a row, and each row includes two groups of MCS parameters, that is, the first index can be any index in the MCS table. In this way, two groups of MCS parameters can be indicated by one index, thereby saving signaling overhead, such as indicating the first MCS and the second MCS by one first index.

[0170] The above-mentioned first index corresponds to two groups of MCS parameters, and these two groups of MCS parameters can also be called independent MCS or MCS subsets.

[0171] In some embodiments, there may be a second index in the above-mentioned MCS table, and the second index corresponds to a group of MCS parameters, such as the second index corresponds to the first MCS, that is, there may be two types of indexes in the MCS table, one is the first index, corresponding to two groups of MCS parameters, and the other index is the second index corresponding to a group of MCS parameters. In this way, when communicating through a communication module, it is only necessary to indicate the second index, so that the device only needs to read one group of MCS parameters to save the device computing overhead.

[0172] Since only one MCS table needs to be configured for two communication modules, configuration overhead can be saved. In addition, since the first MCS and the second MCS are MCS parameters in the same row of the MCS table, the overhead of MCS indication can be reduced, such as only one MCS index needs to be indicated.

[0173] Optionally, the first code rate or the second code rate, wherein the first code rate is the channel coding code rate corresponding to the two groups of MCS parameters, or the rate-matched code rate of one group of MCS parameters in the two groups of MCS parameters is the second code rate, and the channel coding code rate corresponding to the two groups of MCS parameters is the second code rate.

[0174] Among them, the above-mentioned first code rate is the channel coding code rate corresponding to the two groups of MCS parameters, which can be understood as the first code rate corresponding to the above-mentioned first index is the channel coding code rate corresponding to the above-mentioned two groups of MCS parameters. For example, the first code rate corresponding to the above-mentioned first index is the channel coding code rate corresponding to the above-mentioned first MCS and the second MCS. In this way, for two groups of MCS parameters, only one channel coding code rate needs to be configured in the MCS table, thereby saving the overhead of the MCS table.

[0175] The rate matching code rate of one set of MCS parameters in the above two sets of MCS parameters is the second code rate, and the channel coding code rate corresponding to the two sets of MCS parameters is the second code rate. It can be understood that the second code rate indicated by the above first index is both the rate matching code rate of one set of MCS parameters and the channel coding code rate corresponding to the two sets of MCS parameters. For example, the second code rate corresponding to the above first index is the rate matching code rate of the above first MCS and the channel coding code rate of the above first MCS and the second MCS, that is, the above second code rate is a comprehensive code rate, thereby saving the overhead of the MCS table.

[0176] In some implementations, the MCS table may be the MCS table shown in Table 2;

[0177] Table 2:

[0178]

[0179] Wherein, modulation order 1 and modulation order 2 refer to the modulation orders of the first communication module and the second communication module respectively;

[0180] Modulation mode 1 (optional) and modulation mode 2 (optional) refer to the modulation modes of the first communication module and the second communication module respectively, and have the same interpretation as option 1;

[0181] The forward error correction (FEC) code rate represents the first code rate, which represents: the code rate of channel coding, excluding the code rate change caused by rate matching, that is, the channel coding code rates corresponding to the two sets of MCS parameters;

[0182] Code rate 1 and code rate 2 refer to code rate changes of the first communication module and the second communication module due to rate matching, that is, code rates of rate matching of two sets of MCS parameters;

[0183] In some embodiments, the FEC code rate and code rate 1 can also be combined into a comprehensive code rate (i.e., the second code rate mentioned above) to determine and generate the HARQ RV transmitted by the first communication module, while code rate 2 is used alone as the code rate for rate matching the HARQ RV by the second communication module to reduce the complexity of the MCS table; alternatively, the FEC code rate and code rate 2 can also be combined, and code rate 1 can be indicated alone to reduce the complexity of the MCS table.

[0184] As an optional implementation, in the parallel transmission, the data transmitted through the first communication module and the data transmitted through the second communication module belong to at least one physical channel or logical channel.

[0185] The data transmitted by the first communication module and the data transmitted by the second communication module belong to at least one physical channel or logical channel, including:

[0186] The data transmitted by the first communication module and the data transmitted by the second communication module belong to one physical channel or logical channel, that is, the two communication modules transmit the same physical channel or logical channel, or the two modules simultaneously carry the same physical channel or logical channel, such as the two modules repeatedly transmit, multiplex or mix the data of the same physical channel or logical channel; or

[0187] The data transmitted by the first communication module and the data transmitted by the second communication module belong to multiple physical channels or logical channels, that is, the two communication modules transmit multiple physical channels or logical channels, or the two modules carry multiple physical channels or logical channels at the same time, such as the two modules repeatedly transmit the data of multiple physical channels or logical channels, or, in multiplex transmission, one module transmits one channel and the other module transmits another channel, or, in mixed transmission, one module transmits the first channel and the other module transmits the second channel, and the two modules also repeatedly transmit the third channel.

[0188] The above physical channels include but are not limited to:

[0189] Downlink control channel, downlink shared channel, paging channel, broadcast channel, uplink control channel, uplink shared channel, etc.

[0190] In this implementation, at least one physical channel or logical channel can be transmitted through the first communication module and the second communication module, thereby improving the transmission flexibility of the communication device.

[0191] As an optional implementation, the method further includes:

[0192] The first device sends capability information of the first device, where the capability information is used to indicate at least one of the following:

[0193] whether the first device supports parallel transmission of the first communication module and the second communication module;

[0194] MCS capabilities supported by the first communication module;

[0195] The MCS capability supported by the second communication module.

[0196] The first device may send capability information to the second device or the network side device.

[0197] Since the capability information of the first device is sent, the device receiving the capability information can perform capability-matched communication with the first device based on the capability information of the first device, thereby improving the communication performance of the first device.

[0198] Optionally, when the capability information indicates that the first device supports parallel transmission of the first communication module and the second communication module, the capability information is further used to indicate at least one of the following:

[0200] The above parallel transmission mode includes at least one of the following:

[0201] Repeat transmission, multiplex transmission, and mixed transmission.

[0202] The above-mentioned maximum TB data for multiplexing indicates the maximum number of TBs that can be transmitted in parallel.

[0203] The maximum number of HARQ RV parts multiplexed above indicates the maximum number of HARQ RV parts that can be transmitted in parallel.

[0204] The capability information described above can improve the accuracy of capability reporting, so as to achieve more matched communication transmission between the first device and the second device.

[0205] Optionally, the MCS capability supported by the first communication module includes at least one of the following:

[0206] The maximum transmission duration supported by the first communication module, the maximum number of symbols supported by the first communication module, the maximum number of resource units RE supported by the first communication module, the maximum number of bits of the sending buffer of the first communication module, the maximum transmission block size TBS of the sending buffer of the first communication module, the maximum number of bits of the receiving buffer of the first communication module, the maximum TBS of the receiving buffer of the first communication module, the number of HARQRVs supported by the first communication module, the maximum number of bits that can be carried by one HARQ RV of the first communication module, the modulation mode supported by the first communication module, the modulation mode set supported by the first communication module, the symbol time length supported by the first communication module, and the symbol rate supported by the first communication module;

[0210] The MCS capability information can improve the accuracy of capability reporting, so as to achieve more matched communication transmission between the first device and the second device.

[0211] As an optional implementation, the method further includes:

[0212] The first device receives transmission indication information, where the transmission indication information is used to indicate relevant information of the TB, where the relevant information of the TB includes at least one of the following:

[0213] Parallel transmission mode, the number of TBs to be sent by the first device, the number of TBs to be received by the first device, transmission parameters of at least one TB, transmission parameters of at least one HARQ RV part, TBS, and the number of bits of HARQ RV.

[0214] The transmission indication information may be transmission indication information sent by the second device, the network side device or the relay and received by the first device.

[0215] The number of TBs to be sent by the first device is the number of TBs to be sent by the first device through parallel transmission of the first communication module and the second communication module. For example, for repeated transmission, the number of TBs is 1, and for multiplexed transmission / mixed mode, the number of TBs can be 1 or >1.

[0216] The number of TBs to be received by the first device is the number of TBs to be received by the first device when the second device performs parallel transmission, that is, the number of TBs to be sent by the second device through the first communication module and the second communication module in parallel.

[0217] The transmission parameters of at least one TB may be understood as indicating the transmission parameters with TB as the granularity, and the transmission parameters of the at least one HARQ RV part may be understood as indicating the transmission parameters with the HARQ RV part as the granularity.

[0218] Optionally, the transmission parameter includes at least one of the following:

[0219] Original code rate, rate matching code rate, modulation mode, modulation order, transmission resources, position relationship of overlapping bits, mapping rules of overlapping bits, data selection rules, and data discarding rules; wherein the position relationship of overlapping bits, the mapping rules of overlapping bits, the data selection rules, and the data discarding rules are: the position relationship of overlapping bits, the mapping rules of overlapping bits, the data selection rules, and the data discarding rules when the first communication module and the second communication module perform repeated transmission or mixed transmission.

[0220] The transmission parameters may be transmission parameters indicated with a TB as the granularity, or may be transmission parameters indicated with a HARQ RV part as the granularity.

[0221] The above transmission resources include resource locations or resource quantities.

[0222] The positional relationship of the overlapping bits indicates the positional relationship of the overlapping bits if there is overlap between the bits transmitted by the first communication module and the bits transmitted by the second communication module in the case of repeated transmission or mixed mode.

[0223] The above overlapping bit mapping rule indicates that in case of repeated transmission or mixed mode, if there is overlap between the bits transmitted by the first communication module and the bits transmitted by the second communication module, the overlapping bit mapping rule is indicated.

[0224] The above data selection rule or data discarding rule indicates that the HARQ RV of the second communication module selects or discards bits of the HARQ RV of the first communication module.

[0225] In this implementation, the above transmission parameters can enable the first device to perform more accurate data transmission, thereby improving the transmission performance of the first device.

[0226] In some implementations, the transmission parameters may be transmission parameters indicated for the first communication module and the second communication module respectively, that is, the transmission parameters corresponding to the first communication module and the second communication module are indicated separately.

[0227] In an embodiment of the present application, a first device performs parallel transmission through a first communication module and a second communication module, and the parallel transmission includes: repeated transmission, multiplexed transmission or mixed transmission; wherein, in the repeated transmission, the data transmitted through the first communication module and the data transmitted through the second communication module are the same data; in the multiplexed transmission, the data transmitted through the first communication module and the data transmitted through the second communication module are different data; in the mixed transmission, the data transmitted through the first communication module and the data transmitted through the second communication module include the same data, and there are also different data in the data transmitted through the first communication module and the data transmitted through the second communication module. In this way, parallel transmission can be achieved through two communication modules, thereby improving the transmission performance of the communication device, such as the reliability of the communication device transmission can be improved through repeated transmission, the rate of the communication device transmission can be improved through multiplexed transmission, and the reliability and rate of the communication device transmission can be improved through mixed transmission.

[0228] See also Fig.11 , Fig.11 is a flow chart of a data receiving method provided in an embodiment of the present application, such as Fig.11 As shown, the following steps are included:

[0229] Step 1101: A second device receives a first path of data sent by a first device through a first communication module, and receives a second path of data sent by the first device through a second communication module.

[0230] The second device may be a terminal or a network side device.

[0231] The second device receiving the first data sent by the first device through the first communication module may be the second device receiving the first data through the first communication module, and the second device receiving the second data sent by the first device through the second communication module may be the second device receiving the second data sent by the first device through the second communication module through the second communication module. It should be noted that the receiving method of the second device is not limited in the embodiments of the present application.

[0232] Optionally, the method further includes:

[0233] The second device acquires at least one HARQ RV data based on the first path of data and the second path of data, and decodes the at least one HARQ RV data.

[0234] In this implementation, when the first data path and the second data path include partial data in the same HARQ RV, the two data paths can be combined into HARQ RV data, and then the complete HARQ RV data can be decoded to improve the accuracy of data decoding.

[0235] It should be noted that this embodiment is Figure 4 The implementation of the second device corresponding to the embodiment shown in the figure can be found in the specific implementation of the second device. Figure 4 To avoid repeated description, the related description of the embodiment shown in the present invention will not be repeated in detail.

[0236] The following takes the first communication module as the main communication module and the second communication module as the extremely low power consumption communication module as an example to illustrate the method provided in the embodiment of the present application through multiple embodiments:

[0237] Embodiment 1:

[0238] This embodiment describes repeated transmission, which is as follows:

[0239] Repeated transmission means that the information transmitted by the two modules is the same data (the same TB), which is used to increase the reliability of transmission. In some cases, the transmission rate of the extremely low power communication module may not match that of the main communication module, and its transmission power, symbol rate and modulation order may not be as good as those of the main communication module. Therefore, the MCS used by the extremely low power communication module may be different from that of the main communication module. However, in order for the decoder to merge the data from the two modules, the TBs processed by the two modules are generated by the same channel coding, that is, the same coding type, coding method (such as generation matrix, check matrix, etc.), and original code rate (code rate without rate matching). After channel coding, the two modules can generate different HARQ RVs and modulate them separately according to the indicated MCS. In order to match the transmission rate of the extremely low power module, the data length of a HARQ RV of the two modules may be different (for example, each RV of the main communication module has X bits, while each RV of the extremely low power communication module has Y bits), and the extremely low power communication module can also selectively discard the data after channel coding, for example: mainly retain the system bits, thereby reducing the number of bits actually required to be sent. To further accommodate the difference in transmission rates between the two modules, the HARQ RVs of the two modules can also be asynchronous, for example, the time required for the main communication module to transmit 2 RVs corresponds to the time required for the ultra-low power communication module to transmit 1 RV. At the receiving end, only one HARQ RV needs to be received, no matter which module it comes from, to update the LLR of the relevant bits on the TB, and then try to decode it.

[0240] Specifically, for the sending end (i.e., the first device mentioned above), there may be the following three implementation options:

[0241] Option 1: If Figure 6As shown, after channel coding, the two modules perform rate matching, HARQ RV generation and interleaving on the coded data according to the indicated MCS (MCS1 and MCS2 respectively). The rate matching of the ultra-low power communication module also assumes the function of bit selection, and selectively retains or discards the data after channel coding, such as mainly retaining the system bits. Since the original code rate of the channel coding needs to be the same, only one MCS is needed to determine the code rate of the channel coding; and the rate matching code rate (and specific operation) and the modulation order adopted by the two modules can be different. In this option, the two modules can generate their own HARQ RV processes completely independently.

[0242] Option 2: If Figure 7 As shown, when generating HARQ RV, it is first generated according to the needs of the main communication module, including rate matching, and then the generated HARQ RV data is submitted to the extremely low power communication module for bit selection. At this time, the bit selection needs to be adjusted according to the code rate of MCS2 indicated to the extremely low power communication module, in order to match the number of bits with the transmission rate, and then modulate according to the modulation order of MCS2. Compared with option 1, option 2 basically does not need to modify the processing flow of the main communication module, and reduces the additional overhead of preparing HARQ RV separately for the extremely low power communication module, but the disadvantage is that the HARQ RV sent by each extremely low power communication module is based on the bit selection of 1 HARQ RV generated by the main communication module, which reduces the diversity of transmission.

[0243] Option 3: Note that the bit selection in Option 2 is actually a kind of rate matching. Therefore, in Option 3, the rate matching can be placed after the HARQ RV is generated, such as Figure 8 The transmitter first needs to split the TB to generate multiple HARQRVs, and then submit them to the main communication module and the ultra-low power communication module for rate matching and modulation to obtain the final transmitted signals.

[0244] Embodiment 2:

[0245] This embodiment describes multiplexing, specifically as follows:

[0246] In multi-channel transmission, two channels of data with certain correlation but different characteristics are sent, for example, HARQ RV data is divided into two non-overlapping parts, and the receiving end needs to receive both channels of data to obtain a complete HARQ RV for decoding. A specific method can be obtained by modifying option 3 of embodiment 1, such as Fig. 9As shown. The difference is that after the HARQ RV is generated, the data will be divided into two parts (RV Part I and RV Part II). RV Part I enters the main communication module for transmission, while RV Part II enters the ultra-low power communication module for transmission. The MCS of the two may be different. However, it should be noted that Part I and Part II together constitute an RV. During the initial transmission, at least two parts must be fully acquired for decoding. However, if it is not the initial transmission, if the receiving end only obtains Part I or Part II, it may also be used for decoding. Furthermore, an RV may be divided into more parts. The advantage of this is that it takes advantage of the fact that the transmission time of the two modules may be unequal. While waiting for one module to complete the transmission of one RV Part, the other module can send multiple different RV Parts.

[0247] Furthermore, the RV Parts transmitted by the two modules may also come from different RVs, which is equivalent to transmitting the next RV in advance.

[0248] Embodiment three:

[0249] This embodiment describes hybrid transmission, which is as follows:

[0250] Hybrid transmission combines the above two methods, in which part of the data transmitted by the two modules is repeated, while the other part is different.

[0251] The simplest case is that two modules transmit the same HARQ RV of the same TB at the same time, and some bits are overlapped and some bits are different from each other, then this purpose can be achieved by only overlapping some bits of RV Part I and RVPart II in Embodiment 2. Similar to Embodiment 2, the RV Parts transmitted by the two modules can also come from different RVs of the same TB, which is equivalent to transmitting the next RV in advance.

[0252] Another case is that the independent data parts of the two modules come from different TBs. Fig.10A most general form is shown, in which the MAC layer submits three TBs, the main communication module and the ultra-low power communication module repeatedly transmit TB1, and transmit TB2 and TB3 respectively. Since data from two TBs need to be transmitted on the same physical layer, data concatenation is required. Without loss of generality, it is assumed that the channel coding rate of TB2 and TB1 is controlled by MCS1, the channel coding rate of TB3 is controlled by MCS2, and the code rate and modulation order of the final transmission of the two modules are controlled by MCS1 and MCS2 respectively.
