[0051] In order to enable ordinary persons in the art to better understand the technical solutions of the present disclosure, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings.

[0052] It should be noted that the terms "first", "second", etc. in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0053] At present, when two devices in a communication connection transmit information, for example, when a base station sends a physical downlink shared channel (PDSCH) message to a user equipment (UE) or a UE sends a physical uplink shared channel (PUSCH) message, the length of the original data sent, i.e., the protocol data unit (PDU) may be less than the actual number of allocated resources. In this case, in order to meet the requirements of the protocol or algorithm, padding bits need to be added after the PDU.

[0054] In the related art, padding bits are directly filled with zeros after the PDU, that is, all the padding bits are 0. The padding bits filled with zeros are random bits after scrambling, and the corresponding constellation points are evenly distributed in the constellation diagram, which is similar to the constellation diagram of the valid data PDU. This zero-filling method cannot transmit valuable information and wastes a lot of transmission power.

[0055] Figure 1 The flowchart of a data transmission method of an embodiment of the present disclosure is as follows. It should be noted that the data transmission method of the present embodiment can be applied to a data transmission device, which can be configured in an electronic device or chip so that the electronic device or chip can perform a data transmission function.

[0056] Among them, the electronic device can be any device with computing capabilities, such as a personal computer (PC), a mobile terminal, a terminal device, a server, a network device, etc. The mobile terminal can be, for example, a vehicle-mounted device, a mobile phone, a tablet computer, a personal digital assistant, a wearable device, and other hardware devices with various operating systems, touch screens and / or display screens.

[0057] In addition, the data transmission device may also be software in an electronic device, etc. The software may be, for example, data transmission software, etc. In addition, the data transmission device may also be the first device in the first device and the second device in communication connection. In the following embodiments, the execution subject is taken as the first device as an example for description.

[0058] like Figure 1 As shown, the method comprises the following steps:

[0059] Step 101, transmitting a first message to a second device; the first message includes: first information and fill information; the fill information indicates the second information; or, the fill information corresponds to a first constellation point in a constellation diagram; the distance between the first constellation point and the center constellation point of the constellation diagram is less than or equal to a distance threshold.

[0060] In an embodiment of the present disclosure, a first device may transmit a first message to a second device that is communicatively connected to the first device; the first device may concatenate the first information and the fill information to obtain the first message; the first information included in the first message may refer to PDU data, and the second information indicated by the fill information in the first message may be the same as or different from the first information.

[0061] In the disclosed embodiment, the constellation diagram is a combination of all symbol points of the modulated signal on the in-phase component (In-phase, I) / quadrature component (Quadrature, Q) plane, and the constellation diagram defines the mapping relationship between the signal distribution of the modulation technology and the modulated digital bits.

[0062] Specifically, after random bits are modulated, they are mapped to specific symbol points on the constellation diagram. Different modulation technologies (such as QPSK, 16-QAM, 64-QAM, etc.) will have different constellations, and each symbol point represents a specific set of bit combinations.

[0063] In the embodiment of the present disclosure, the first constellation point may refer to a constellation point close to the central constellation point of the constellation diagram.

[0064] It should be noted that the first constellation point corresponding to the filling information is close to the central constellation point of the constellation diagram, which can reduce the transmission power of the first message.

[0065] In the data transmission method of the embodiment of the present disclosure, a first message is transmitted to a second device; the first message includes: first information and fill information; the fill information indicates the second information; or, the fill information corresponds to the first constellation point in the constellation diagram; the distance between the first constellation point and the central constellation point of the constellation diagram is less than or equal to a distance threshold; wherein, in the case where the fill information indicates the second information, filling by the fill information can transmit additional second information to the second device, thereby improving the network experience between the devices; in the case where the fill information corresponds to the first constellation point in the constellation diagram, the first constellation point is close to the central constellation point of the constellation diagram, and filling by the fill information can reduce the transmission power of the first message.

[0066] Figure 2 This is a flow chart of a data transmission method according to another embodiment of the present disclosure. It should be noted that the data transmission method according to this embodiment can be applied to a data transmission device, which can be configured in an electronic device or a chip so that the electronic device or the chip can perform a data transmission function.

[0067] Among them, the electronic device can be any device with computing capabilities, such as a personal computer (PC), a mobile terminal, a terminal device, a server, a network device, etc. The mobile terminal can be, for example, a vehicle-mounted device, a mobile phone, a tablet computer, a personal digital assistant, a wearable device, and other hardware devices with various operating systems, touch screens and / or display screens.

[0068] In addition, the data transmission device may also be software in an electronic device, etc. The software may be, for example, data transmission software, etc. In addition, the data transmission device may also be the first device in the first device and the second device in communication connection. In the following embodiments, the execution subject is taken as the first device as an example for description.

[0069] like Figure 2 As shown, the method comprises the following steps:

[0070] Step 201, transmitting a first message to a second device; the first message includes: first information and filling information; the filling information indicates second information, the second information includes the first information and / or local information of the first information, or the second information includes device information of the first device transmitting the first message.

[0071] In an embodiment of the present disclosure, the first device transmitting the first message is a network device, the second device is a terminal device, and the first message is a physical downlink shared channel PDSCH message; or, the first device is a terminal device, the second device is a network device, and the first message is a physical uplink shared channel PUSCH message.

[0072] In the disclosed embodiment, the first device may repeatedly group the first information, such as the PDU, until the data length of the first message reaches the number of resources actually allocated for the transmission and processing of the first message. It should be noted that the second information may include repeated information of the first information, and may also include repeated information of partial information of the first information.

[0073] like Figure 3 As shown, Figure 3 This is a schematic diagram of a first message, where PDU represents first information and PDU repetition represents padding information.

[0074] Among them, determining the filling information based on the first information and / or the local information of the first information can achieve repeated sending of the first information and / or the local information of the first information, thereby improving the reliability and robustness of the first message transmission.

[0075] In the embodiment of the present disclosure, when the second information includes the device information of the first device that transmits the first message, the format of the padding information may be a format agreed upon with the second device, and the padding information may be referred to as a characteristic bit. Figure 4 As shown, Figure 4 This is another schematic diagram of the first message, where PDU represents the first information and the additional information represents the padding information.

[0076] In an embodiment of the present disclosure, the first device is a network device, and the second device is a terminal device; the device information of the first device includes at least one of the following: whether the network device uses beamforming based on a sounding reference signal SRS; whether an edge precoding resource block group (Precoding Resource Block Group, PRG) and an adjacent PRG use the same beamforming; scheduling information of terminal devices other than the second device in a multi-user multiple-input multiple-output (Multi-User Multiple-Input Multiple-Output, MU-MIMO) scenario.

[0077] Wherein, in the case that the first device is a network device, the network device may determine the filling information according to the device information of the network device.

[0078] Among them, SRS-based beamforming refers to using the SRS sent by the terminal device to measure the downlink channel characteristics, and then optimize the beamforming parameters of the network device; whether the edge PRG and the adjacent PRG use the same beamforming can explain the strategy adopted by the network device when configuring the PRG. If the same beamforming is used, it usually means that the network device tries to simplify the configuration and reduce complexity, or believes that adjacent areas have similar channel conditions.

[0079] It should be noted that, when the first device is a network device and the second device is a terminal device, the fill information is determined based on the device information of the network device, and valuable information such as additional network device capabilities can be delivered to the terminal device through the fill information.

[0080] In an embodiment of the present disclosure, the first device is a terminal device, and the second device is a network device; the device information of the first device includes at least one of the following: whether the terminal device has at least two independent power amplifiers (Power Amplifier, PA); whether the terminal device has the ability to perform joint channel estimation on multiple time slots; the insertion loss value of at least two transmitting antennas of the terminal device; and the mobility status of the terminal device.

[0081] Wherein, when the first device is a terminal device, the terminal device may determine the filling information according to the device information of the terminal device.

[0082] The device information of the first device may further include whether multiple carriers share the same PA in carrier aggregation (CA) and dual connectivity (DC) scenarios.

[0083] It should be noted that, when the first device is a terminal device and the second device is a network device, the fill information is determined based on the device information of the terminal device, and valuable information such as additional terminal device capabilities can be transmitted to the network device through the fill information.

[0084] In the data transmission method of the embodiment of the present disclosure, a first message is transmitted to a second device; the first message includes: first information and padding information; the padding information indicates second information, and the second information includes the first information and / or local information of the first information, or the second information includes device information of the first device transmitting the first message; wherein, in the case where the second information includes the first information and / or local information of the first information, the first information and / or local information of the first information can be repeatedly sent through the padding information, thereby improving the reliability and robustness of the first message transmission; in the case where the second information includes the device information of the first device transmitting the first message, additional valuable device information can be delivered to the second device through the padding information.

[0085] In the case where the filling information corresponds to the first constellation point in the constellation diagram, in order to illustrate how the filling information is obtained, the present disclosure provides another data transmission method, Figure 5 Flow chart of the data transmission method of this embodiment of the present disclosure. It should be noted that the data transmission method of this embodiment can be applied to a data transmission device, which can be configured in an electronic device or chip so that the electronic device or chip can perform a data transmission function.

[0086] Among them, the electronic device can be any device with computing capabilities, such as a personal computer (PC), a mobile terminal, a terminal device, a server, a network device, etc. The mobile terminal can be, for example, a vehicle-mounted device, a mobile phone, a tablet computer, a personal digital assistant, a wearable device, and other hardware devices with various operating systems, touch screens and / or display screens.

[0087] In addition, the data transmission device may also be software in an electronic device, etc. The software may be, for example, data transmission software, etc. In addition, the data transmission device may also be the first device in the first device and the second device in communication connection. In the following embodiments, the execution subject is taken as the first device as an example for description.

[0088] like Figure 5 As shown, the method comprises the following steps:

[0089] Step 501, determine a scrambling code sequence; the length of the scrambling code sequence is consistent with the amount of resources used for the first message transmission process.

[0090] In the embodiment of the present disclosure, the first device may calculate a scrambling code sequence according to a scrambling code generation formula, wherein the length of the scrambling code sequence is the same as the number of resources used for the first message transmission process.

[0091] Step 502, performing XOR processing and row-column interleaving processing on the scrambling code sequence according to the first constellation point in the constellation diagram to obtain a processed scrambling code sequence; the XOR processing and row-column interleaving processing are pre-transmission processing operations of the first message.

[0092] In the disclosed embodiment, the constellation diagram is determined in combination with Quadrature Amplitude Modulation (QAM); the number of constellation points in the constellation diagram is the same as the order of QAM. The order of QAM includes at least one of the following: 16-order, 64-order, 256-order, 1024-order, etc.

[0093] In the disclosed embodiment, the order of QAM is different, and the constellation point bits of the first constellation point are different:

[0094] a) For 16QAM: every 4 bits are XORed with the expected modulated constellation point bit (the constellation point bit of the first constellation point), and the expected modulated constellation point bit can be xx00 or others.

[0095] b) For 64QAM: every 6 bits are XORed with the expected modulated constellation point bits. The expected modulated constellation point bits can be xx00xx or xx001x or others, where "x" represents 0 or 1.

[0096] c) For 256QAM: every 8 bits are XORed with the expected modulated constellation point bits. The expected modulated constellation point bits can be xx0011xx or xx00111x or others, where "x" represents 0 or 1.

[0097] d) For 1024QAM: every 10 bits are XORed with the expected modulated constellation point bits. The expected modulated constellation point bits can be xx00111111 or xx0011111x or others, where "x" represents 0 or 1.

[0098] In the embodiment of the present disclosure, the XOR-ed scrambled code bits can be interleaved in rows and columns through an interleaver; the number of rows of the interleaver is equal to the modulation order. Specifically, for 16QAM, the number of rows of the interleaver is equal to 4, for 64QAM, the number of rows of the interleaver is equal to 6, for 256QAM, the number of rows of the interleaver is equal to 8, and for 1024QAM, the number of rows of the interleaver is equal to 10.

[0099] Step 503: Delete the first N bits in the processed scrambling sequence; N is the number of bits in the first information.

[0100] In the embodiment of the present disclosure, the scrambling sequence after deleting the first N bits is padding information, and the first information and the padding information are concatenated to obtain the first message.

[0101] Assuming that the number of resources used for the first message transmission processing is 100 bits and the number of bits in the first information is 10, the first 10 bits in the processed scrambling code sequence are deleted to obtain padding information.

[0102] It should be noted that, by performing XOR processing and row-column interleaving processing on the scrambling code sequence according to the first constellation point in the constellation diagram, and determining the filling information based on the processed scrambling code sequence, the constellation point corresponding to the filling information can be made as close as possible to the central constellation point of the constellation diagram, thereby reducing the transmission power of the first message.

[0103] Step 504, transmitting a first message to the second device; the first message includes: first information and filling information; the filling information corresponds to the first constellation point in the constellation diagram.

[0104] Take 256QAM as an example. Figure 6 As shown, Figure 6Schematic diagram of the first constellation point, in which PDU is the first information, and the generated padding is the padding information obtained by deleting the first N bits in the processed scrambling sequence; the random bits are the random bits obtained after performing cyclic redundancy check (CRC), channel coding (coding), rate matching (RM) and scrambling (scramble) on the PDU, and the bits spliced ​​after the random bits are the constellation point bits obtained after performing CRC, coding, RM and scramble on the generated padding; the constellation point in the circle in the constellation diagram is the first constellation point.

[0105] It should be noted that the detailed description of step 504 can be found in Figure 1 Step 101 in the illustrated embodiment will not be described in detail here.
