Fig. 3 is a schematic flowchart of another data transmission method according to an embodiment of the present invention; as shown in fig. 3, this embodiment provides a specific embodiment of a data transmission method, which is specifically described with respect to the methods shown in fig. 1 and fig. 2.

Step 301, determining a shared resource for early data transmission.

Specifically, the step 301 includes:

the communication node (assumed as the base station 1 and the gNB 1) and other communication nodes (assumed as the base stations 2 and the gNB 2) negotiate information for determining shared resources for early data transmission; the shared resources include at least one of: preamble, PRACH, PUCCH, and PUSCH.

Further, the determining the shared resource for data early transmission further includes:

the gNB1 negotiates with the gNB2 to determine at least one of encryption information, integrity protection information and terminal identification information (UE ID), and configures the at least one of the encryption information, integrity protection information and terminal identification information for the terminal; and/or the presence of a gas in the gas,

configuring a logical channel associated with the shared resource for data transmission.

Step 302, transmitting the shared resource for early data transmission to a terminal (UE).

After the communication node (gbb 1 and/or gbb 2) sends the shared resource for early data transmission to the UE, the UE receives the shared resource for early data transmission, that is, performs data transmission based on the shared resource.

Further, when the communication node (gNB 1 and/or gNB 2) transmits the information of the shared resource to the UE, the communication node may also carry information indicating the shared area. The information indicating the shared area comprises at least one of the following information:

the measured RSRP, RSRQ, and/or RSSI ranges of cells under base station 1, gNB 1;

measured range of RSRP, RSRQ and/or RSSI of cells under base station 2, gNB 2;

TA reserved for terminal context (reference, this entry is valid only for UEs that do not move after leaving connected state);

the location of the cell.

Step 303, the UE sends a first message to the communication node using the shared resource.

Specifically, in the application process, for configured or activated multiplexed (duplicate) uplink data, when the UE determines that the uplink data meets the early-transmission condition, the UE may use the shared resource to transmit the uplink data. Here, the early-pass condition may include: the data amount of the uplink data is smaller than the preset threshold, and/or the data delay requirement of the uplink data is lower, specifically, the delay requirement may be greater than the preset threshold.

The UE sending uplink data to the communication node using the shared resource includes:

the UE sends a first message to the gNB1 or the gNB2 using the shared resource, where the first message includes: an RA preamble and a first data block (i.e., the uplink data); the first data block carries terminal identification information (UE ID). Here, the terminal identification information may be similar to the UE ID in message 1 and message 3 in an existing Random Access Channel (RACH).

Here, when the UE sends the first message, the first message including the RA preamble and the first data block may be sent in two steps; first, the UE sends an RA preamble and a message of a partial data block (the message of the partial data block may include length information of a first data block); and secondly, the UE sends the rest first data block.

It should be noted that whether the above method of sending in two steps is adopted depends on the size of the first data block, the coverage of the cell and the location of the UE in the cell (the UE is smaller at the cell edge than the data block sent by the UE at the cell center), for example, when the first data block is larger or the UE is at the cell edge, a problem may occur in data transmission, and at this time, the sending cannot be completed at one time. The first message is open loop power control and cannot be sent too large.

Step 304, informing other communication nodes of receiving the first message.

Specifically, after receiving a first message sent by the UE, gNB1 informs gNB2 of receiving the first message; otherwise, after receiving the first message sent by the UE, gNB2 informs gNB1 of receiving the first message.

Step 305, the communication node determines the second message, and replies the second message to the UE.

Specifically, the step 305 includes:

after receiving the first message, the communication node (gNB 1 and/or gNB 2) negotiates to determine that one gNB sends a second message;

and determining a second message to be replied according to the first message, and determining that the second message comprises downlink data and has a high reliability requirement, so that both gNB1 and gNB2 can send the second message to the UE.

Here, the second message carries information of a shared area, such as information of a base station and a cell.

Before determining a second message to be replied according to the first message, the method further includes: parsing the first message; specifically, the first message carries a UE ID, if the gNB2 receives the first message and determines that the first message is not allocated or not stored with the UE ID, the gNB2 needs to find an anchor base station (which may be the gNB1 or another base station) according to information of a base station and a cell carried in the UE ID, acquire a context (including encryption information and integrity protection information) of the UE, and unwrap a first data block; or directly forwarding the received UE ID and the first data block to the anchor base station, and transmitting the data block to the gNB2 after being decoded by the anchor base station.

In this embodiment, the limitation of Uplink (UL) synchronization is considered (if the time delays TA from the UE to the two base stations are too different, the two base stations cannot receive uplink data of the UE at the same time); the base stations interact shared resources, and further negotiate which shared resources can be used for sharing and multiplexing among communication nodes, and receive data early; and the extent to which resources can be shared.

In this embodiment, the communication node may use the base stations, that is, the gNB1 and the gNB2 (specifically, the process corresponding to the solid line portion in fig. 3 includes step 301, step 302, step 303, step 304, and step 305); the communication nodes may also be DUs, DU1 and DU2.

Specifically, when the communication node is a DU, the communication node may negotiate through the CU, that is, the CU determines which shared resources under different DUs can be used for sharing and multiplexing between base stations, and receives data while transmitting data early, and the plurality of DUs transfer the data to the CU for combination processing, which corresponds to a flow corresponding to a dotted line portion in fig. 3 specifically; the method specifically comprises the following steps:

in step 311, the CU determines the shared resource and sends it to DU1 and DU2.

In another embodiment, after determining the shared resource, the CU may also send the shared resource to DU2, and DU2 sends the shared resource to DU1, which is not limited herein.

Step 313, like step 303, the UE transmits a first message to the communication node using the shared resource.

Step 314, like step 304, informs the other communication nodes of the receipt of the first message.

Step 315, sending the received first message to the CU.

Step 316, the CU determines the second message and sends the second message to the UE via DU1 or DU2.

In a second embodiment, a similar scheme to that in the first embodiment is adopted, except that in this embodiment, after receiving the shared resource, the gNB1 and the gNB2 may form a Dual Connectivity (DC) like structure for the UE, that is, a certain gNB1 has a Convergence layer, and for example, a Packet Data Convergence Protocol (PDCP) and/or a Radio Link Control Protocol (RLC) takes effect only in a certain communication node.

A third embodiment, a similar scheme to that in the first embodiment is adopted, except that in this embodiment, semi-static reserved resources may be adopted as the shared resources, that is, semi-static reserved resources (which may be common semi-static reserved resources or grouped semi-static reserved resources) that are interactively shared between the communication nodes; further negotiating a shared encryption information and/or integrity protection information (e.g., MAC-I information) between the communication nodes; the communication node sends the shared semi-static reserved resource to the UE. Specifically, the information of the semi-static reserved resource can be broadcast by the cell when the cell sends the system message; or, the cell sends the information of the semi-static reserved resource through a message with a preset format (such as an RRC release message when leaving the RRC connected state).

The communication node and the UE perform data transmission by using the semi-static reserved resource in the same manner as the above scheme, and are not described herein again.

The fourth embodiment provides a data transmission method, which includes:

the first communication node sends information of the shared resources for data transmission to the terminal.

The shared resource for data transmission comprises at least one of the following resources: the shared resource used by the terminal to send the first message (i.e. at least one of preamble, PRACH, PUCCH, and PUSCH described in the method shown in fig. 1), the block chain storage resource of the terminal, the block chain calculation resource of the terminal, the resource occupied by the block chain application information, the block chain storage resource of another terminal related to the terminal, and the sharing rule used for data transmission.

and the communication nodes in the shared area make a judgment on the safety and reliability of the first message by using the sharing rule of data transmission, execute an intelligent contract and feed back a conclusion to the terminal, and optionally feed back the conclusion to the related terminal and the communication nodes.

For example, a vehicle is used as the terminal, the shared resource is used for feeding back road congestion indication information, the security and reliability of the first message are judged by using a sharing rule of data transmission through communication nodes in a sharing area, and then the information is determined not to meet the actual condition, an intelligent contract is executed, punishment is carried out on the terminal reporting the information, and the information reliability level is reduced; on the contrary, if the security and reliability of the first message are judged by the communication node in the shared area by using the sharing rule of data transmission and then the information is determined to be in accordance with the actual situation, an intelligent contract is executed, the terminal reporting the information is appreciated, and the reliability level of the information is improved or maintained.

Fifth, a data transmission method provided in this embodiment includes:

the first communication node sends information of the shared resources for data transmission to the second communication node.

And the communication nodes in the shared area make a judgment on the safety and reliability of the first message by using the sharing rule of data transmission, execute the intelligent contract and feed back the conclusion to the first communication node, and optionally feed back the conclusion to the related communication node and the second communication node.

For example, the second communication node feeds back the road congestion indication information by using the shared resource, when a communication node (i.e., the first communication node) in the shared area determines that "the number of pieces of information of IMSI of the base station requesting the UE", "the number of pieces of tracking area update failure information", or "the number of pieces of RRC connection failure information" is too large, the security and reliability of the second communication node are determined by using a sharing rule of data transmission, and then it is determined that the road congestion indication information does not conform to the actual situation (for example, when the road congestion indication information fed back by a certain second communication node is different from the information fed back by other majority of second communication nodes, it is considered that the road congestion indication information fed back by the second communication node does not conform to the actual situation), an intelligent contract is executed, and it is determined that the second communication node is a pseudo base station; on the contrary, if the communication node in the shared area judges the safety and reliability of the second communication node by using the sharing rule of data transmission and then determines that the information accords with the actual condition, the intelligent contract is executed to determine that the second communication node is a reliable base station. Through the operation, the pseudo base station is prevented from acquiring the IMSI of the UE by triggering the flow and then carrying out illegal events.

For example, if the number of pieces of information of IMSI of the base station requesting the UE, the number of pieces of tracking area update failure information, or the number of pieces of RRC connection failure information, which are fed back to the second communication node by the terminal on the shared resource, is too large, and the security and reliability of the second communication node are determined by using the sharing rule, and then the number of pieces of information is determined not to meet the actual situation (specifically, if the number of pieces of information of IMSI of the base station requesting the UE, the number of pieces of tracking area update failure information, or the number of pieces of RRC connection failure information, which are fed back by the terminal according to the request of the second communication node, such as the base station, is too large, then the number of pieces of information is determined not to meet the actual situation), an intelligent contract is executed, and it is determined that the second communication node is a pseudo base station; on the contrary, if the communication node in the shared area utilizes the sharing rule of data transmission to judge the safety and reliability of the second communication node to be information according with the actual condition, the intelligent contract is executed to judge that the second communication node is a reliable base station. Through the operation, the pseudo base station can be prevented from acquiring the IMSI of the UE by triggering the flow and then carrying out illegal affairs.
