[0111] like figure 1 As shown, the embodiment of the present invention provides an information transmission method, which is applied to a terminal, and specifically includes the following steps:

[0112] Step 11: When the first physical uplink control channel PUCCH resource carrying the first hybrid automatic repeat request acknowledgment HARQ-ACK and the second PUCCH resource carrying the second HARQ-ACK overlap in the time domain, if the preset condition, then determine the cyclic shift used for transmitting the first HARQ-ACK according to the information bits of the second HARQ-ACK.

[0113] Wherein, the preset condition is: the first HARQ-ACK is transmitted using the first PUCCH format, and the second HARQ-ACK is transmitted using the second PUCCH format; or, the first HARQ-ACK is transmitted using the first PUCCH format. The PUCCH format is used for transmission, and the number of bits of the second HARQ-ACK does not exceed the predetermined number of bits.

Abstract

The present invention provides an information transmission method, a terminal, and a base station, wherein the method on the terminal side includes: overlapping in the time domain between the first PUCCH resource carrying the first HARQ-ACK and the second PUCCH resource carrying the second HARQ-ACK In the case of , if the preset condition is satisfied, the cyclic shift used to transmit the first HARQ-ACK is determined according to the information bits of the second HARQ-ACK; on the first PUCCH resource, the cyclic shift is used to transmit the first HARQ-ACK ACK; where the preset condition is: the first HARQ-ACK is transmitted using the first PUCCH format, and the second HARQ-ACK is transmitted using the second PUCCH format; or, the first HARQ-ACK is transmitted using the first PUCCH format, and the second The number of bits of the two HARQ‑ACKs does not exceed the predetermined number of bits. The present invention solves the problem in the prior art that there is no specific transmission scheme when PUCCH resources carrying different HARQ-ACK information overlap in the time domain.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to an information transmission method, a terminal and a base station. Background technique [0002] In 5G NR, a terminal may transmit multiple different services at the same time. For ultra-reliable and low latency communications (Ultra-Reliable and Low Latency Communications, URLLC) services, considering the characteristics of low latency, it supports sub-slot-based hybrid automatic repeat request response in a time slot Transmission of (Hybrid Automatic Repeat Request ACK, HARQ-ACK) information. The uplink control information (UCI) of the enhanced mobile broadband (enhancedMobile Broadband, eMBB) service is transmitted based on time slots. Different services have different priorities, and it may appear that the Physical Uplink Control Channel (PUCCH) carrying HARQ-ACK information of higher priority services (such as URLLC services) and the physical uplink contr...
