Description

(Cross-reference of related applications) This application claims priority to Chinese Patent Application No. 201910143059.9, filed in China on February 26, 2019, and all contents of that application are incorporated herein by reference. This disclosure relates to the field of telecommunications technology, and more particularly to information transmission methods and terminals. When a terminal feeds back Hybrid Automatic Repeat request Response (HARQ-ACK) information corresponding to Physical Downlink Shared Channel (PDSCH) transmission to an Unlicensed Communication System (New Radio Unlicensed Spectrum, NR-U) based on downlink scheduling signaling, and the downlink scheduling signaling is located at the end of the Channel Occupancy Time (COT) requested by network equipment, such as a base station gNB, the Physical Uplink Control channel within this COT is also affected. Due to factors such as the inability to direct the Channel (PUCCH) resource, uncertainty in acquiring a radio channel before the terminal transmits the PUCCH based on the directive information, and interference from potential hidden nodes during PUCCH transmission, the terminal may be unable to feed back HARQ-ACK information as expected. In situations where a terminal is unable to provide HARQ-ACK information as expected, the gNB can request or trigger the terminal to report previously unsuccessful HARQ-ACK information. However, when the gNB requests or triggers the terminal to report previously unsuccessful HARQ-ACK information, the relevant technology does not yet know how the terminal will effectively transmit the triggered, previously unsuccessful HARQ-ACK information. The problem to be solved The embodiments of this disclosure provide an information transmission method and terminal to solve the problem in related technologies where, when a network device triggers a terminal to report HARQ-ACK information that had previously failed to be fed back, the terminal does not yet know how to effectively transmit the triggered HARQ-ACK information that had previously failed to be fed back. This is a flowchart of the information transmission method in the embodiment of the present disclosure.This is a schematic diagram illustrating the counting of DAI numbers in PDSCH transmission in a specific embodiment of the present disclosure.This is a schematic diagram of the cascading connections of the HARQ-ACK subcodebooks corresponding to the PDSCH set in a specific embodiment of the present disclosure.This is one of the schematic diagrams of the structure of the terminal in the embodiment of the present disclosure.This is the second schematic diagram of the structure of the terminal in the embodiment of the present disclosure. The terms "first," "second," etc., used in the specification and claims of this application are intended to distinguish similar subjects and are not necessarily intended to describe a specific order or sequence of steps. It should be understood that the data used in this manner is interchangeable where appropriate, so that the embodiments of this application described herein may be carried out in an order other than those illustrated or described herein. Furthermore, the terms "includes" and "have" and any variations thereof are intended to intentionally cover non-exclusive "includes," for example, a process, method, system, product, or apparatus that includes a series of steps or units may not necessarily be limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or are specific to those processes, methods, products, or apparatus. The technologies described in this text are not limited to Long Term Evolution (LTE) / LTE-Advanced (LTE-A) systems, but also include various wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), and Single-carrier Frequency Division Multiple Access (Single-carrier). This can also be applied to Frequency-Division Multiple Access (SC-FDMA) and other systems. The terms "system" and "network" are always used interchangeably. CDMA systems can implement radio technologies such as CDMA2000, Universal Terrestrial Radio Access (UTRA), etc. UTRA includes Broadband Code Division Multiple Access (WCDMA) and other CDMA variations. TDMA systems can implement radio technologies such as Global System for Mobile Communication (GSM). OFDMA systems can enable radio technologies such as Ultra Mobile Broadband (UMB), Evolution-UTRA (E-UTRA), IEEE 802.11 (Wireless Fidelity, Wi-Fi), IEEE 802.16 (Worldwide Interoperability for Microwave Access, WiMAX), IEEE 802.20, and Flash-OFDM. UTRA and E-UTRA are part of the Universal Mobile Telecommunications System (UMTS). LTE and higher levels of LTE (e.g., LTE-A) are newer UMTS versions that utilize E-UTRA. UTRA, E-UTRA, UMTS, LTE, LTE-A, and GSM are described
