[0027] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings and in conjunction with embodiments.

[0028] It should be noted that the terms "first", "second", etc. in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0029] First, the related technologies involved in this disclosure are described:

[0030] In wireless communication technology, the capacity of wireless channels 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 data packets transmitted with errors to the total number of data packets transmitted within a certain time interval. The BLER largely reflects the match between the capacity of the wireless channel and the amount of information transmitted. To achieve a lower BLER, the amount of information can be loaded onto the spectrum resources, that is, the modulation order and code rate of the transmitted data can be reduced. This can achieve a very low BLER or even zero BLER. This approach ensures a low BLER by keeping the amount of information transmitted far below the channel capacity. However, this wastes the capacity of the wireless channel, meaning that more spectrum resources are required to transmit the same amount of data, which is a precious and limited resource. On the other hand, if the amount of information loaded onto the spectrum resources far exceeds the channel capacity, a large number of data packets will be transmitted with errors. Throughput and spectral efficiency are calculated based on the amount of correctly transmitted data or information. Therefore, if a large number of data packets are erroneous, throughput and spectral efficiency will not be very high.

[0031] Maximizing spectrum efficiency is a long-standing goal in wireless communications. In this context, the target BLER (BLER) is introduced to ensure optimal spectrum efficiency. When the BLER equals the target BLER, the spectrum efficiency of data transmission is considered optimal. For example, in eMBB scenarios, the target BLER is 0.1, meaning the ratio of transmitted error packets to the total number of transmitted packets is 1:10. At this BLER, spectrum efficiency is considered optimal and is one of the most important objectives in eMBB scenarios.

[0032] In addition, the target BLER can be used to guarantee not only spectrum efficiency but also transmission delay and jitter. For example, the target BLER in the URLLC scenario is 10 -5 , that is, the ratio of the number of data packets with transmission errors to the total number of packets transmitted is 1:10 5 Such a low target BLER ensures that almost all transmitted data packets can be demodulated correctly, ensuring reliability. It also greatly reduces the occurrence of retransmissions, reduces data transmission delay and jitter, and ensures determinism.

[0033] Target BLER plays an important role in wireless communication, ensuring communication quality and system performance.

[0034] However, in the related art, the target BLER is fixed. That is, as mentioned 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 However, a fixed target BLER cannot optimally adapt to the changing air interface wireless channel and service quality requirements. In particular, the target BLER in the URLLC scenario is artificially set without sufficient verification, which will lead to resource waste due to the overly conservative target BLER. For example, if the actual BLER required for a specific service scenario is 0.01, if a target BLER of 0.1 is selected, reliability and certainty cannot be guaranteed; if a target BLER of 10 is selected, the target BLER of 0.1 cannot be guaranteed. -5 If the target BLER is not achieved, resources will be wasted, resulting in low spectrum efficiency.

[0035] In response to the above-mentioned problems existing in the related art, corresponding solutions are proposed in the embodiments of the present disclosure. In the embodiments of the present disclosure, the target BLER can be configured to maximize the spectrum efficiency SE (Spectral Efficiency).
