[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, Time Division Duplex) is a wireless communication technology mainly used in mobile communication systems. TDD realizes two-way communication by time division, that is, on the same frequency, the base station and the user equipment (such as mobile phone) transmit and receive signals in different time periods.

[0034] MS: (Mobile Station, Mobile Station). Mobile station is a user equipment, usually used in mobile communication network, with mobile station refers to terminal equipment or user terminal, it is the equipment for wireless communication with base station. Common user equipment includes mobile phone, tablet computer, notebook computer (with wireless network card), Internet of Things equipment, etc.

[0035] RB: RB is the abbreviation of "Resource Block" (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 allocation strategy of resource blocks will affect the throughput of the network and the experience of users.

[0036] BS: is the abbreviation of Base Station. In mobile communication systems, the 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, Timing Advance). Used to adjust the time synchronization between the base station and the mobile device, to ensure that in wireless communication, each device can send and receive signals at the correct time. This is particularly important because the distance between the mobile device and the base station will affect the propagation time of the signal, and in turn affect the reliability and effectiveness of communication, mainly used for signal synchronization.

[0038] PDCP(Packet Data Convergence Protocol, Packet Data Convergence Protocol) is a protocol used in mobile communication networks, mainly 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 mobile networks, and it serves as an important protocol in the Radio Access Network (RAN), between upper layer protocols (such as IP, RLC) and lower layer protocols (such as RLC, MAC).

[0039] QPSK: (Quadrature Phase Shift Keying, Quadrature Phase Shift Keying) is a modulation technique used in digital communication systems to convert digital data into analog signals for transmission. In QPSK, each sequence of digital bits is mapped to 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 within each symbol interval, thereby improving spectral efficiency. QPSK is widely used in wireless communication and digital modulation.

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

It is to be noted that the steps shown in the flowchart of 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 herein can be executed in a different order.

[0049] Figure 2 is a flowchart of a data transmission method according to an embodiment of the present disclosure, as Figure 2 shown, the method includes the following steps:

[0050] In step S202, uplink data uploaded by a first terminal in a terminal cluster is received through an uplink channel resource block of the first terminal, the uplink data being obtained by encapsulating data to be uploaded according to an encoding mode of the uplink data of the first terminal, wherein the encoding mode 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, the encoding mode of the uplink data, and an uplink channel resource block of the first terminal.

[0051] In step S204, 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 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 : If the timing advance parameter satisfies a preset condition, re-encapsulate the uplink data and upload it to the base station, wherein the timing 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 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 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, the upper layer terminals {MS2, MS3} receive the uplink data packet of the terminal MS1 on the specific RB, and continue to transfer it to the upper layer {MS4, MS5, MS6} on the same RB; after receiving the uplink data packet, {MS4, MS5, MS6} transfer the MS1 uplink data packet to the base station BS; the base station BS receives the MS1 uplink data packet transferred 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 The timing advance parameter of the first-level terminal MS2, TA MS3 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, during the uplink data transfer process, both the terminals {MS2, MS3} and the terminals {MS4, MS5, MS6} adopt the UM transmission mode when transferring the uplink data of the terminal MS1.

[0056] Through the steps S202 to S208, the uplink data uploaded by the first terminal is received through the uplink channel resource block of the first terminal in the terminal cluster, the uplink data is obtained by encapsulating the data to be uploaded by the first terminal according to the encoding mode of the uplink data of the first terminal, wherein the encoding mode 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 mode of the uplink data and the uplink channel resource block of the first terminal; the control channel signaling message sent by the base station is received through the other terminals in the terminal cluster, and the control channel signaling message at least includes the uplink channel resource block of the first terminal; the time advance parameter is obtained from the uplink data through the other terminals in the terminal cluster; and in the case that the time advance parameter meets the preset condition, the uplink data is re-encapsulated and uploaded to the base station, so as to achieve the purpose of enhancing the uplink transmission in the communication link by using the terminal cluster for relaying, thereby realizing the technical effect of improving the uplink signal strength, and further solving the technical problem of uplink and downlink imbalance in the mobile network scene in the related art. The following will be described in detail.

[0057] In some embodiments of the present application, receiving the uplink data uploaded by the first terminal through the uplink channel resource block of the first terminal includes: in the case that the first level terminal in the other terminals has a plurality of uplink channel resource block service states in the target frequency domain, the uplink data is received through the uplink channel resource block of the first level terminal, and the first level terminal is the terminal in the level closest to the first terminal, wherein the resource block of each terminal in the terminal cluster is allocated by the base station after dividing the uplink channel resource into a plurality of resource blocks according to the time and frequency domain, and each terminal is allocated with a resource block of all frequency domains in a time domain.

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

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

[0060]

[0061] When the MS i In In the service state, if a certain No data, the Empty, not assigned to other MS x Use, wherein the MS i Indicates the i-th terminal, MS x Indicates other terminals except MS i .

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

[0063] At the same time, other terminals {MS2, MS3, …, MS n} also know the uplink channel resource allocated by the base station BS to the terminal MS1 through the control channel signaling message of the base station BS: uplink RB channel resource uplink RB resource (first terminal uplink channel resource block), in , 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 first level terminal receives the uplink data, in the case that the reference signal power of the uplink signal of the first terminal is within a preset power interval, the information in the header of the uplink data is obtained.

[0065] Specifically, the first terminal obtains the information in the header of the uplink data in the case that the uplink signal reference power of needs to meet formula (1).

[0066]

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

[0068] In the case of meeting formula (1), it is determined that there is a certain 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 the preset parameter threshold and the reference power of the base station signal received by the terminal of the first level is greater than the preset power threshold, re-encapsulating the uplink data and uploading it to the base station.

[0070] The terminal MS1 receives the scheduling information of the base station BS about uplink data transmission (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 in FIG, the encapsulation package consists of two parts: a header and data to be uploaded.

[0071] For example, the first terminal MS1 uploads uplink data to the first-level terminal MS2. The following conditions need to be met:

[0072]

[0073] In the above formula, represents the timing advance parameter of the first terminal, The timing advance parameter of the terminal MS2 in the first layer, THESH TA {Threshold} represents the preset parameter threshold, The reference power of the base station signal received by the terminal MS2, THESH RSRP {Threshold} represents the preset power threshold, Indicates 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: is idle, indicating that the terminal MS2 is in the state without data on the uplink.

[0076] The uplink data is re-encapsulated, re-encapsulated in the format as Figure 9 shown, and the time advance parameter of the terminal at the first level and the data to be uploaded are obtained. The time advance parameter of the terminal at the first level and the data to be uploaded are encoded according to the encoding mode of the uplink data, and the re-encapsulation of the uplink data is completed.

[0077] In some embodiments of the present application, the uplink data uploaded by the terminals at multiple levels in the other terminals to the base station in stages includes: uploading the uplink data uploaded by the terminals at the highest level to the base station, and the uplink data is used for combining by the base station according to the diversity reception mode.

[0078] As shown in Figure 10 , the terminal MS2 re-encapsulates the uploaded data of the first terminal MS1 to obtain transit data, and distributes the transit data to the uplink where the terminal MS2 is located.

[0079] By analogy, the terminals (terminals at the first level) {MS3, …} in the vicinity upload the uplink data of the first terminal MS1 in the above manner;

[0080] The terminals {MS4, MS5, MS6, …} at the next level receive the transit data, and perform step-by-step transit transmission on the uplink transit data packets of {MS2, MS3}, until the transmission is performed to the base station. As shown in Figure 11 , the base station BS receives the uplink data packets about MS1 from the terminals {MS4, MS5, MS6, …} after the transit.

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

[0083] The first receiving module 30 is configured to receive uplink data uploaded by a first terminal in the terminal cluster through an uplink channel resource block of the first terminal, wherein the uplink data is obtained by encapsulating data to be uploaded according to an encoding mode of the uplink data of the first terminal, and the encoding mode 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, the encoding mode of the uplink data and the uplink channel resource block of the first terminal.
