[0002] With the continuous development of mobile communication technology, higher frequency spectrum resources (such as millimeter wave and terahertz bands) are being widely explored and applied in the new generation of mobile networks, especially towards the evolution of 6G technology. These high-frequency band signals have higher bandwidth and lower latency, but they also face the challenges of poor signal propagation characteristics and weak penetration, especially in non-line-of-sight or complex environments. Current mobile networks, such as 4G LTE and 5G NR, mainly adopt a point-to-point communication mode between the base station (BS) and the user terminal (MS). This mode performs well in low frequency bands, but when evolving to higher frequency bands, due to the signal attenuation of high frequency bands and the power limitation of user equipment (UE), it leads to an imbalance between the forward link (base station to terminal) and the reverse link (terminal to base station). Specifically, due to the power limitation of the terminal equipment, the signal strength and reliability of the uplink are often lower than those of the downlink, which is particularly obvious in high-frequency communications.

[0029] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0030] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application 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 interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0031] The information collected in the embodiments of the present application is information and data authorized by the user or fully authorized by all parties, and the collection, storage, use, processing, transmission, provision, disclosure and application of the relevant data comply with the relevant laws, regulations and standards of the relevant regions, take necessary confidentiality measures, do not violate public order and good morals, and provide corresponding operation entrances for users to choose to authorize or reject automated decision-making results; if the user chooses to reject, the expert decision-making process will be entered.

[0032] In order to better understand the embodiments of the present application, the technical terms involved in the embodiments of the present application are explained as follows:

[0033] TDD: (Time Division Duplex) is a wireless communication technology mainly used in mobile communication systems. TDD achieves two-way communication through time division, that is, on the same frequency, the base station and user equipment (such as mobile phones) send and receive signals in different time periods.

[0034] MS: (Mobile Station). A mobile station is a user device, usually used in mobile communication networks. Mobile station refers to terminal equipment or user terminals, which are devices that communicate wirelessly with base stations. Common user devices include mobile phones, tablets, laptops (with wireless network cards), IoT devices, etc.

[0035] RB: RB is the abbreviation of "Resource Block". In mobile communication systems, especially in LTE (4G) and NR (5G) networks, resource blocks are the basic allocation units of spectrum resources. In LTE and 5G networks, data is allocated to different resource blocks, allowing multiple users to transmit data on the same frequency band at the same time. The resource block allocation strategy affects the network throughput and user experience.

[0036] BS: is the abbreviation of Base Station. In mobile communication systems, a base station is a key component responsible for transmitting and receiving wireless signals. It communicates with mobile terminals (such as mobile phones) through radio waves and transmits these wireless signals to the core network or other base stations through wired or optical fiber networks.

[0037] TA: TA (Timing Advance). Parameters used to adjust the time synchronization between the base station and the mobile device to ensure that each device can send and receive signals at the correct time in wireless communication. This is particularly important because the distance between the mobile device and the base station affects the propagation time of the signal, which in turn affects the reliability and effectiveness of the communication. It is mainly used for signal synchronization.

[0038] PDCP (Packet Data Convergence Protocol). It is a protocol used in mobile communication networks and plays a key role in 4G LTE and 5G NR systems. The main function of PDCP is to process and optimize the transmitted data to improve the efficiency and performance of the network. PDCP is an important part of the data link layer in the mobile network. As an important protocol in the radio access network (RAN), it is between the upper layer protocols (such as IP, RLC) and the lower layer protocols (such as RLC, MAC).

[0039] QPSK: (Quadrature Phase Shift Keying). It is a modulation technique used in digital communication systems to convert digital data into analog signals for transmission. In QPSK, each digital bit sequence is mapped into a set of adjacent symbols, each symbol representing a specific phase state. Specifically, QPSK modulates the phase of two orthogonal carriers so that each symbol can represent four possible phase states: 0°, 90°, 180°, and 270°. This technique allows two bits to be transmitted in each symbol interval, thereby improving spectral efficiency. QPSK is widely used in wireless communications and digital modulation.

[0040] UM (Unacknowledged Mode), data transmission does not require confirmation and retransmission mechanism. It is a transparent mode in the RLC protocol and is mainly used to transmit error-free user data with lower latency and higher transmission efficiency.

It should be noted that Figure 1 This is merely one example of a particular embodiment and is intended to illustrate the types of components that may be present in the computer terminal described above.

[0048] In the above-mentioned operating environment, an embodiment of the present application provides an embodiment of a data transmission method. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0049] Figure 2 is a flow chart of a data transmission method according to an embodiment of the present application. Figure 2 As shown, the method comprises the following steps:

[0050] Step S202: receiving, through an uplink channel resource block of a first terminal in a terminal cluster, uplink data uploaded by the first terminal, wherein the uplink data is obtained by the first terminal encapsulating data to be uploaded according to an encoding method of the uplink data of the first terminal, wherein the encoding method of the uplink data is obtained from scheduling information sent by a base station to the first terminal, and the scheduling information at least includes: an identifier of the first terminal, an encoding method of the uplink data, and an uplink channel resource block of the first terminal;

[0051] Step S204: receiving a control channel signaling message sent by a base station through other terminals in the terminal cluster, wherein the control channel signaling message includes at least: an uplink channel resource block of the first terminal;

[0052] Step S206, obtaining a timing advance parameter from uplink data through other terminals in the terminal cluster;

[0053] Step S208: When the time advance parameter satisfies a preset condition, the uplink data is repackaged and uploaded to the base station, wherein the time advance parameter is used to represent a parameter for adjusting time synchronization between the base station and the terminal.

[0054] Figure 3 A communication system is shown, such as Figure 3 As shown, it includes: base stations and terminal clusters MS1, MS2, MS3, ..., MS6. Taking the first terminal as MS1 and the other terminals as MS2, MS3, ..., MS6 as an example, in terms of the downlink data transmission mode, the downlink adopts the data transmission mode from the base station BS directly to the terminal MS1, and in terms of the uplink data transmission mode, as shown in FIG. Figure 4 As shown, the uplink terminal MS1 performs uplink data transmission in a specific RB (uplink channel resource block of the first terminal) according to the scheduling mode UM transmission mode of the base station BS; at the same time, after the upper-layer terminals {MS2, MS3} receive the uplink data packet of the terminal MS1 on the specific RB, they continue to forward it to the upper-layer {MS4, MS5, MS6} on the same RB; after {MS4, MS5, MS6} receive the uplink data packet, they forward the MS1 uplink data packet to the base station BS; the base station BS receives the MS1 uplink data packet forwarded by {MS4, MS5, MS6}, and performs data merging processing according to the diversity reception mode; thereby completing the transmission of the entire MS1 uplink data. It can be understood that TA MS1 represents the time advance parameter of the first terminal MS1, TA MS2 represents the timing advance parameter of the first-level terminal MS2, TA MS3 represents the timing advance parameter of the first-level terminal MS3, TA MS4 TA MS5 TA MS6 Indicates the timing advance parameters of the second-level terminals MS4, MS5, and MS6.

[0055] It should be noted that, in the process of uplink data transfer, no matter it is the terminal {MS2, MS3} or the terminal {MS4, MS5, MS6}, in the process of transferring the uplink data of the terminal MS1, the UM transmission mode is adopted.

[0056] Through the above steps S202 to S208, uplink data uploaded by the first terminal is received through the uplink channel resource block of the first terminal in the terminal cluster, and the uplink data is obtained by the first terminal encapsulating the data to be uploaded according to the encoding method of the uplink data of the first terminal, wherein the encoding method of the uplink data is obtained from the scheduling information sent by the base station to the first terminal, and the scheduling information at least includes: the identifier of the first terminal, the encoding method of the uplink data and the uplink channel resource block of the first terminal; a control channel signaling message sent by the base station is received through other terminals in the terminal cluster, and the control channel signaling message at least includes: the uplink channel resource block of the first terminal; a time advance parameter is obtained from the uplink data through other terminals in the terminal cluster; when the time advance parameter meets the preset condition, the uplink data is re-encapsulated and uploaded to the base station, wherein the time advance parameter is used to represent the parameter for adjusting the time synchronization between the base station and the terminal, thereby achieving the purpose of enhancing the uplink transmission in the communication link by relaying by the terminal cluster, thereby achieving the technical effect of improving the uplink signal strength, and then solving the technical problem of uplink and downlink imbalance in the mobile network scenario in the related technology. The following details are given.

[0057] In some embodiments of the present application, uplink data uploaded by the first terminal is received through the uplink channel resource block of the first terminal, including: when the service status of multiple uplink channel resource blocks in the target frequency domain of the first-level terminal among the other terminals is idle, the uplink data is received through the uplink channel resource block of the first-level terminal, the first-level terminal is the terminal in the layer closest to the first terminal, wherein the resource block of each terminal in the terminal cluster is allocated after the base station divides the uplink channel resources into multiple resource blocks according to the time and frequency domains, and each terminal is allocated resource blocks of all frequency domains in a time domain.

[0058] like Figure 5 As shown, the base station BS divides the uplink channel resources according to the time domain and the frequency domain; each RB represents a time domain and a frequency domain resource, such as Figure 6 As shown, the base station BS and n service-state terminals {MS1, MS2, MS3, ..., MS n During the service communication process, the base station BS allocates all RB resources in the frequency domain of a certain time domain to a single terminal MS;

[0059] For example, the base station BS has a total of m RBs in the frequency domain of a single time domain of an uplink channel, and provides n service-state terminals {MS1, MS2, MS3, ..., MS n The uplink time-frequency domain RB resources of} are

[0060]

[0061] When MS i exist When performing business operations, if a If there is no data, the Empty, not allocated to other MSs x Use, among others, MS i Indicates the i-th terminal, MS x In addition to MS i Other terminals.

[0062] Specifically, the method of receiving the scheduling information is as follows: the terminal MS1 is in the service state, and the base station BS sends scheduling information about uplink data transmission (uplink MS1 specific identifier, coding method, uplink channel RB resources of the first terminal, etc.) to the terminal MS1 through a control channel signaling message;

[0063] At the same time, other terminals {MS2, MS3, ..., MS n}, also through the control channel signaling message of the base station BS, the uplink channel resources allocated by the base station BS to the terminal MS1 are obtained: uplink RB channel resources uplink channel RB resources (uplink channel resource block of the first terminal), In the figure, k represents the time domain where the RB is located, and (i, j) represents the frequency interval where the RB is located.

[0064] After the terminal at the first layer receives the uplink data, when the reference signal power of the uplink signal of the first terminal is within a preset power interval, information in a header of the uplink data is acquired.

[0065] Specifically, the first terminal When the uplink signal reference power satisfies formula (1), the information in the header of the uplink data is obtained.

[0066]

[0067] In the formula, represents a reference signal power of an uplink signal of the first terminal, Indicates the minimum value within the preset power range. Indicates the maximum value of the preset power range.

[0068] When formula (1) is satisfied, it is determined that there is a certain degree of isolation between MS1 ​​and MS2.

[0069] Among them, the specific steps of obtaining the time advance parameter from the uplink data through other terminals in the terminal cluster include: obtaining the time advance parameter of the first terminal in the uplink data; when the difference between the time advance parameter of the first terminal and the time advance parameter of the terminal of the first level is greater than a preset parameter threshold and the reference power of the base station signal received by the terminal of the first level is greater than a preset power threshold, repackaging the uplink data and uploading it to the base station.

[0070] The terminal MS1 receives the scheduling information about uplink data transmission from the base station BS (coding mode, uplink channel resource block of the first terminal) After that, the uploaded data is encrypted and encapsulated at the PDCP layer. The encapsulation method is as follows: Figure 7 As shown, the encapsulation package consists of two parts: a header and data to be uploaded.

[0071] Take the first terminal MS1 uploading uplink data to the first-level terminal MS2 as an example. The following conditions need to be met:

[0072]

[0073] In the above formula, represents a timing advance parameter of the first terminal, represents the timing advance parameter of the terminal MS2 in the first level, THESH TA {Threshold} indicates the preset parameter threshold. represents the reference power of the base station signal received by the terminal MS2, THESH RSRP {Threshold} indicates the preset power threshold. Represents multiple resource blocks in the target frequency domain.

[0074] In some embodiments of the present application, the specific steps of repackaging the uplink data and uploading it to the base station are as follows: obtaining the service status of multiple resource blocks of the first-level terminal in the target frequency domain; when the service status of multiple resource blocks of the first-level terminal in the target frequency domain is idle, repackaging the uplink data and uploading it to the base station step by step through multiple levels of terminals among the other terminals, and the terminal at the highest level among the multiple levels is closest to the base station.

[0075] Specifically, taking the first terminal as MS1 and the first-level terminal as MS2 as an example, Figure 8 As shown, It is used to indicate that the distance between the terminal MS2 and the base station is closer than that between the terminal MS1 and the base station; It is used to indicate that the reference power of the base station signal received by the terminal MS2 needs to be higher than the preset power threshold; the uplink channel RB of the terminal MS2: If it is empty, it means that the terminal MS2 is in There is no data on the device and it is in idle state.

[0076] The uplink data is repackaged, such as Fig. 9 The format shown is repackaged to obtain the time advance parameters of the first-layer terminal and the data to be uploaded; the time advance parameters of the first-layer terminal and the data to be uploaded are encoded according to the encoding method of the uplink data to complete the repackaging of the uplink data.

[0077] In some embodiments of the present application, multiple layers of terminals among the other terminals are uploaded to the base station step by step, including: uploading multiple uplink data uploaded by multiple terminals at the highest level to the base station, and the multiple uplink data are used for the base station to merge according to the diversity reception mode.

[0078] like Fig.10 As shown, the terminal MS2 repackages the uploaded data of the first terminal MS1 to obtain the transfer data, and distributes the transfer data to the terminal MS2. Upward launch.

[0079] By analogy, the nearby terminals (terminals in the first layer) {MS3, ...} upload the uplink data of the first terminal MS1 in the above manner;

[0080] After receiving the transfer data, the terminals {MS4, MS5, MS6...} at the next higher level transfer the uplink transfer data packets {MS2, MS3} step by step until they are transmitted to the base station. Fig.11 As shown, the base station BS receives the uplink data packet about MS1 transferred from the terminals {MS4, MS5, MS6...}.

[0081] It can be understood that the data transmission method provided in the embodiment of the present application adopts an uplink transmission mode in which the terminal uplink is relayed step by step; and utilizes the uplink relay transmission between terminals step by step to solve the imbalance problem of the uplink and downlink links of the mobile network.

[0083] A first receiving module 30 is configured to receive uplink data uploaded by a first terminal in a terminal cluster through an uplink channel resource block of the first terminal, wherein the uplink data is obtained by encapsulating the data to be uploaded by the first terminal according to a coding method of the uplink data of the first terminal, wherein the coding method of the uplink data is obtained from scheduling information sent by a base station to the first terminal, and the scheduling information at least includes: an identifier of the first terminal, a coding method of the uplink data, and an uplink channel resource block of the first terminal;
