In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention are described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The first embodiment is as follows:
the embodiment provides a UCI multiplexing configuration method, which can accurately configure the BetaOffset value during UCI multiplexing, thereby obtaining the number of REs under the condition that UCI does not exceed the maximum appropriate code rate during multiplexing on the PUSCH according to the accurately configured BetaOffset value, saving resources occupied during UCI multiplexing, increasing the number of REs of the corresponding PUSCH, effectively reducing the PUSCH code rate, and improving the demodulation performance of the PUSCH. Please refer to fig. 1, the UCI multiplexing configuration method provided in this embodiment includes:
s101: and acquiring the bit length of UCI which needs to be multiplexed on a Physical Uplink Shared Channel (PUSCH).
In this embodiment, the bit length of the UCI may be represented by L. And it should be understood that the bit length of the UCI in this embodiment can be flexibly set according to an application scenario or a requirement. For example, the length of the UCI may be 1bit, 2bit, 32bit to 11bit, or 12bit or more. For the sake of easy understanding, the present embodiment will be described below by taking 12 bits as an example. The calculation method of the BetaOffset value of the UCI with 1bit, 2bit, 3-11 bit or other lengths is the same as 12bit, and is not described in detail in this embodiment.
S102: and acquiring the signal-to-noise ratio (PUSCH SINR) of the PUSCH.
For the acquiring method of the PUSCH SINR, the existing measurement or calculation method of the signal to noise ratio of the PUSCH may be adopted, and details are not repeated here.

S103: and acquiring the corresponding transport Block size Tbsize, Modulation and Coding Scheme (MCS), Physical Resource Block Number (PRB Number) and the corresponding target code rate of the UCI under the signal-to-noise ratio PUSCH SINR when the UCI is multiplexed on the PUSCH according to the signal-to-noise ratio PUSCH SINR.
In the present embodiment, the method of acquiring Tbsize, MCS, and PRB num according to the signal-to-noise ratio PUSCH SINR may be acquired based on, but not limited to, the method specified in the existing various standards. For example, the acquisition may be performed based on the Tbsize, MCS, and PRB num acquisition methods specified in the standard protocols such as standard 3.8214 and 3.8.212. And will not be described in detail herein.
In this embodiment, obtaining the target code rate corresponding to the UCI under the signal-to-noise ratio according to the signal-to-noise ratio PUSCH SINR includes:

The mapping relation between the signal-to-noise ratio and the code rate comprises the corresponding relation between the value of each signal-to-noise ratio and the value of the code rate under the set block error rate value.
The BLER value in this embodiment may be flexibly set according to requirements such as a specific application scenario. For example, it may be 0.01, or 0.008, or 0.02, etc. For the convenience of understanding, the present embodiment will be described below by taking an example in which the BLER value is 0.01 and the bit length L of the UCI is 12 bits.

Polar codes correspond to different modulation modes under different SINR, and decoding performances of the Polar codes are different. In this example, the bit length L of the UCI is equal to 12 bits, and Polar coding is adopted, where the Polar coding includes but is not limited to BPSK/QPSK/16QAM/64QAM/256QAM modulation schemes, and at this time, corresponding to the above several debugging schemes, when the BLER value is 0.01 and the bit length L of the UCI is 12 bits, the mapping relationship between the signal-to-noise ratio and the code rate under the several debugging schemes can be obtained through simulation, please refer to fig. 2 to 6, respectively.
For example, assuming that the obtained PUSCH SINR value is 12db, please refer to fig. 4, and the corresponding obtained target code rate is 0.85. And the query mode of the target code rate corresponding to other PUSCH SINR values is analogized, and is not described herein again.
