[0025] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0026] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and do not have to be used to describe a specific order or sequence.

[0027] First, the related technologies involved in the present invention will be described:

[0028] In wireless communication technology, the capacity of the wireless channel is constantly changing and uncertain. Therefore, the amount of information that can be correctly transmitted depends on the capacity of the wireless channel. The Block Error Rate (BLER) is the ratio of the number of erroneously transmitted data packets to the total number of transmitted data packets within a certain time interval. BLER largely reflects the matching degree between the wireless channel capacity and the amount of transmitted information. To achieve a lower BLER, less information can be loaded on the spectrum resources, that is, the modulation order and code rate of the transmitted data are reduced. This can achieve a very low BLER or even zero BLER. This approach is to make the amount of transmitted information much smaller than the channel capacity to ensure a smaller BLER. However, this will waste the capacity of the wireless channel, that is, more spectrum resources are required to transmit the same amount of data, and spectrum resources are very precious and limited. On the other hand, if the amount of information far exceeding its channel capacity is loaded on the spectrum resources, a large number of erroneously transmitted data packets will occur. Since throughput and spectral efficiency are calculated based on the amount of correctly transmitted data or information, the throughput and spectral efficiency will not be very high in the case of a large number of packet errors.

[0029] Maximizing spectral efficiency is the goal that wireless communication has been pursuing. In this case, the introduction of the target BLER is to ensure the optimal spectral efficiency. When the BLER is equal to the target BLER, the spectral efficiency of data transmission is considered to be optimal. For example, the target BLER in the eMBB scenario is 0.1, that is, the ratio of the number of erroneously transmitted data packets to the total number of transmitted data packets is 1:10. At this BLER, the spectral efficiency is considered to be optimal, and spectral efficiency is one of the most important goals in the eMBB scenario.

[0030] In addition, the target BLER can not only be used to ensure spectral efficiency, but also to ensure transmission delay and jitter. For example, the target BLER in the URLLC scenario is 10 -5 , that is, the ratio of the number of erroneously transmitted data packets to the total number of transmitted data packets is 1:10 5 . Such a low target BLER ensures that almost all transmitted data packets can be correctly demodulated, ensuring reliability. At the same time, it also greatly reduces the occurrence of retransmissions, reduces the transmission delay and jitter of data, and ensures determinacy.

[0031] The target BLER plays an important role in wireless communication, ensuring communication quality and system performance.

[0032] However, in the related technology, the target BLER is fixed. That is, as described above, the target BLER in the eMBB scenario is fixed at 0.1, and the target BLER in the URLLC scenario is fixed at 10 -5, the fixed target BLER cannot optimally adapt to the changing radio access channel and service quality of service requirements. In particular, the target BLER in the URLLC scenario is artificially set without sufficient verification, resulting in resource waste caused by the over-conservatism of the target BLER. For example, if the actual required BLER for a specific service scenario is 0.01, choosing a target BLER of 0.1 cannot guarantee reliability and determinism; if choosing a target BLER of 10 -5 , it will waste resources and lead to too low spectral efficiency.

[0033] In view of the above problems in the related art, in the embodiments of the present invention, corresponding solutions are proposed. In the embodiments of the present invention, the target BLER can be configured to maximize the spectral efficiency SE (Spectral Efficiency).

[0034] The present invention will be described below in conjunction with embodiments:

Among them, the above mobile terminal may further include a transmission device 106 for communication functions and an input / output device 108. Those of ordinary skill in the art can understand that Figure 1 the structure shown is only schematic and does not limit the structure of the above mobile terminal. For example, the mobile terminal may further include more or fewer components than those shown in Figure 1 , or have a different configuration from that shown in Figure 1 .

[0036] The memory 104 can be used to store computer programs, such as software programs and modules of application software, such as the computer program corresponding to the wireless communication method in the embodiments of the present invention. The processor 102 executes various functional applications and data processing by running the computer programs stored in the memory 104, that is, the above-mentioned method is implemented. The memory 104 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memories, or other non-volatile solid-state memories. In some instances, the memory 104 may further include a memory remotely disposed relative to the processor 102, and these remote memories can be connected to the mobile terminal through a network. Examples of the above-mentioned network include, but are not limited to, the Internet, an intranet, a local area network, a mobile communication network, and combinations thereof.

[0037] The transmission device 106 is used to receive or send data via a network. Specific examples of the above-mentioned network may include a wireless network provided by a communication provider of the mobile terminal. In one instance, the transmission device 106 includes a network adapter (Network Interface Controller, abbreviated as NIC), which can be connected to other network devices through a base station and thus can communicate with the Internet. In one instance, the transmission device 106 may be a radio frequency (Radio Frequency, abbreviated as RF) module, which is used to communicate with the Internet wirelessly.
