[0002] In 5G networks, network slicing can be used to provide different service-level agreements (SLAs) for different types of services.

[0003] If each control service is divided into a network slice, it will result in too many time and frequency resources being reserved in the cell. This will reduce the wireless resource utilization of the entire network cell, thereby reducing the cell throughput. Summary of the Invention

[0030] Next, the embodiments of the present application are described in detail.

[0031] The embodiment of the present application provides a data transmission method, which is applied to a base station, such as Figure 1 As shown, the method may include the following steps:

[0032] S11. When receiving the SR sent by the user equipment UE, if the size value of the data packet to be transmitted currently corresponding to the UE is not the set size value, the size value of the data packet to be transmitted is updated to the set size value, and a first uplink resource is allocated to the UE according to the set size value, and a first uplink authorization information is sent to the UE, so that the UE sends the first data packet within the first TTI indicated by the first uplink authorization information, based on the first uplink resource indicated by the first uplink authorization information, using the first transmission mode indicated by the first uplink authorization information and adopting the first modulation method indicated by the first uplink authorization information.

[0033] In this step, the size value is set to the sum of the size threshold set for the control data packet of the target type and the size value of the buffer status report BSR.

[0034] S12. When receiving the target BSR sent by the UE, if the channel attribute of the logical channel corresponding to the logical channel ID carried in the target BSR is a low latency attribute, and the size of the data packet to be transmitted corresponding to the logical channel carried in the target BSR is not greater than the size threshold, a first uplink resource is allocated to the UE, and a second uplink authorization information is sent to the UE, so that the UE sends a second data packet within the second TTI indicated by the second uplink authorization information, based on the first uplink resource indicated by the second uplink authorization information, using the second transmission mode indicated by the second uplink authorization information and adopting the second modulation method indicated by the second uplink authorization information.

[0035] It should be noted that, in the embodiment of the present application, the first transmission mode is the transmission mode used by the base station when receiving the SR, and the first modulation mode is the modulation mode used by the base station when receiving the SR.

[0036] The second transmission mode is a single-stream transmission mode and is different from the first transmission mode;

[0037] The second modulation mode is the lowest order modulation mode and is different from the first modulation mode.

[0038] In addition, in the embodiment of the present application, the target type may be a power line communication (PLC) type or a remote control type, etc. For example, the size threshold value is 20 bits, etc.

[0039] Furthermore, in an embodiment of the present application, for the base station, when receiving the SR sent by the UE, if the size value of the data packet to be transmitted currently corresponding to the UE is a set size value, the step of allocating the first uplink resource to the UE according to the set size value is directly executed.

[0040] That is to say, the base station has previously updated the current corresponding size value of the data packet to be transmitted of the UE. When receiving the SR sent by the UE again, there is no need to modify the current corresponding size value of the data packet to be transmitted of the UE. It directly allocates the first uplink resource to the UE according to the set size value and sends the first uplink authorization information to the UE.

[0041] Furthermore, in the embodiment of the present application, the base station may further perform the following operations:

[0042] If the channel attribute of the logical channel corresponding to the logical channel ID carried in the target BSR is not a low latency attribute, or if the channel attribute of the logical channel corresponding to the logical channel ID carried in the target BSR is a low latency attribute and the size of the data packet to be transmitted corresponding to the logical channel carried in the target BSR is greater than the size threshold, then allocate a second uplink resource according to the size of the control class data packet to be transmitted corresponding to the logical channel carried in the target BSR, and send a third uplink authorization information to the UE, so that the UE sends a third data packet within a third TTI indicated by the third uplink authorization information, based on the second uplink resource indicated by the third uplink authorization information, using the third transmission mode indicated by the third uplink authorization information and adopting the third modulation method indicated by the third uplink authorization information;

[0043] The third transmission mode is a transmission mode used by the base station when receiving the target BSR, and is different from the second transmission mode;

[0044] The third modulation mode is a modulation mode used by the base station when receiving the target BSR, and is different from the second modulation mode.

[0045] Here, the third transmission mode may be the same as or different from the first transmission mode; the third modulation mode may be the same as or different from the first modulation mode.

[0046] The above data transmission method is described in detail below with reference to specific embodiments.

[0047] like Figure 2 As shown in the figure, it is assumed that UE1 needs to send data packet 1 to the base station at a certain moment (for example, data packet 1 is a PLC data packet, and the corresponding size value is 20 bits), but there is no uplink resource, and the size value of the data packet to be transmitted corresponding to UE1 on the base station side (denoted as DseVom) is the default size value (not the set size value). In this case, the interaction process between UE1 and the base station is as follows:

[0048] 1. UE1 sends a Scheduling Request (SR) to the base station.

[0049] 2. When the base station receives the SR, it finds that the DseVom corresponding to UE1 is not the set size value. At this time, the base station updates the DseVom corresponding to UE1 to the set size value, and allocates uplink resources to UE1 according to the set size value (recorded as uplink resource 1), and sends uplink authorization message 1 to UE1.

[0050] Here, the transmission mode indicated by the uplink authorization message 1 is the transmission mode used by the base station when receiving the SR (not the single-stream transmission mode); the modulation mode indicated by the uplink authorization message 1 is the modulation mode used by the base station when receiving the SR (not the lowest-order modulation mode).

[0051] 3. After receiving uplink grant message 1, UE1 sends data packet 1 within the transmission time interval (TTI) indicated by uplink grant message 1, based on uplink resource 1 indicated by uplink grant message 1, using the transmission mode indicated by uplink grant message 1 and adopting the modulation method indicated by uplink grant message 1.

[0052] Since there are sufficient uplink resources, UE1 can successfully send data packet 1.

[0053] 4. Assuming UE1 needs to continue sending PLC data packet 2, UE1 continues to send a Buffer Status Report (BSR) to the base station. The BSR carries the logical channel identifier (ID) of the logical channel on which PLC data packet 2 is to be sent and the size of the pending data packet (i.e., the size of PLC data packet 2). Furthermore, the channel attribute of this logical channel is low latency.

[0054] 5. When the base station receives the BSR, it finds that the channel attribute of the logical channel corresponding to the logical channel ID carried in the BSR is a low-latency attribute, and the size of the data packet to be transmitted corresponding to the logical channel carried in the BSR is equal to the size threshold. At this time, the base station allocates uplink resource 1 to the UE and sends uplink authorization information 2 to the UE.

[0055] Here, the transmission mode indicated by uplink grant message 2 is single-stream transmission mode, and the modulation method indicated by uplink grant message 2 is the lowest-order modulation method. This can significantly reduce the transmission delay of PLC data packet 2, improving not only wireless resource utilization but also transmission reliability.

[0056] It should be noted that the base station can adjust the transmission mode indicated by the uplink authorization message 2 by modifying the Rank value. For example, the base station can modify the Rank value to 1 to implement the transmission mode indicated by the uplink authorization message 2 as a single-stream transmission mode; the base station can adjust the modulation mode indicated by the uplink authorization message 2 by modifying the modulation and coding scheme (MCS) value. For example, the base station can modify the MCS value to 0 to implement the modulation mode indicated by the uplink authorization message 2 as the lowest-order modulation mode.

[0057] 6. After receiving uplink grant message 2, UE1 sends PLC data packet 2 within the TTI indicated by uplink grant message 2, based on uplink resource 1 indicated by uplink grant message 2, using the transmission mode indicated by uplink grant message 2 and adopting the modulation method indicated by uplink grant message 2.

[0058] As can be seen from the above technical solution, in the embodiment of the present application, the base station can allocate the same uplink resource for target type control packets that need to be sent multiple times on the UE side. This uplink resource can also ensure that the UE can smoothly send the BSR. Moreover, when the base station receives the BSR, it also instructs the UE to use a single-stream transmission mode and the lowest-order modulation method to send the relevant control packets. This not only reduces the number of SRs sent, but also greatly reduces the transmission delay of the target type control packets, thereby improving the utilization of wireless resources and the throughput of the cell where the UE is located.
