Further, the terminal can use the HARQ information based on the TB feedback instead, so that the terminal does not perform the HARQ-ACK feedback of the CBG, but only performs the HARQ-ACK feedback of the TB.

In another embodiment, if CBG feedback is configured, the terminal may compress part of the CBG-based HARQ-ACK feedback information in the UCI to be transmitted. For example, the CBG-based HARQ-ACK feedback information is 8 bits, which can be compressed every two bits to obtain 4 bits of transmission information.

2) The number of bits of UCI to be transmitted is greater than the first bit threshold;

Optionally, the first bit threshold value may be a predetermined value, or may be a value configured in the PUCCH resource by a network side device, that is, a higher layer. For example, the network side device may configure a fixed first bit threshold value in each PUCCH resource, and the first bit threshold value configured in different PUCCH resources may be the same or different; The PUCCH resource is configured with a fixed first bit threshold.

In one embodiment, after acquiring the UCI to be transmitted and selecting the PUCCH resource, the terminal can determine whether the number of bits of the UCI to be transmitted is greater than the first bit threshold value configured in the PUCCH resource, and determine whether the number of bits of the UCI to be transmitted is greater than the first bit threshold value configured in the PUCCH resource, and the number of bits of the UCI to be transmitted is When the code rate is greater than the first bit threshold value, it is determined to adopt the transmission mode of compressing UCI, and the UCI to be transmitted is compressed so that the UCI compression information is smaller than the first bit threshold value.

3) The number of bits of UCI to be transmitted is greater than the second bit threshold, and the PUCCH format indicated by the physical uplink control channel resource indication (PUCCH Resource Indication, PRI) obtained by the terminal is PUCCH format 0 or PUCCH format 1;

As shown in Figure 3, the initial number of UCI bits to be transmitted by the UE is n1, and the code rate is q1. When the PRI indicates to transmit in the PUCCH resource shown in Figure 3, due to the limitation of the pre-configured maxCodeRate threshold, that is, q1 is high At the maxCodeRate threshold, the UE can discard part of the CSI part information to obtain UCI compression information.
