Embodiment Construction

[0066] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to specific embodiments and accompanying drawings.

[0067] The information transmission method of the embodiment of the present invention is applied to a terminal, such as figure 1 shown, including:

[0068] Step 101: When the HARQ-ACK and channel state information CSI of the semi-persistent scheduling SPS physical downlink shared channel PDSCH need to be transmitted at the same time, according to the sum of the bits of the HARQ-ACK of the SPS PDSCH and the CSI, Select a PUCCH resource set from multiple pre-configured PUCCH resource sets.

[0069] Here, when it is necessary to transmit the HARQ-ACK of the semi-persistent scheduling SPS physical downlink shared channel PDSCH and the channel state information CSI at the same time, it means that the PUCCH carrying the HARQ-ACK of the SPS PDSCH and ...

Abstract

The present invention provides an information transmission method, a terminal and a base station to solve the problem that when the HARQ-ACK of the SPS PDSCH is transmitted on the PUCCH, if there is a conflict with the CSI transmitted on another PUCCH, there is no clear solution for how to transmit. The present invention includes: when the HARQ-ACK and CSI of the SPS PDSCH need to be transmitted at the same time, according to the sum of the bits of the HARQ-ACK and CSI of the SPS PDSCH, a PUCCH resource set is selected from a plurality of pre-configured PUCCH resource sets; The PUCCH resource in the PDCCH indicating the activation of the downlink SPS resource refers to the time domain, and at least one PUCCH resource is determined in the selected PUCCH resource set; the HARQ-ACK and CSI of the SPS PDSCH are simultaneously sent on the determined at least one PUCCH resource.

Description

technical field [0001] The present invention relates to the technical field of communication applications, in particular to an information transmission method, a terminal and a base station. Background technique [0002] With the development and changes of mobile communication service requirements, many organizations such as ITU have begun to study new wireless communication systems (5 Generation New RAT, 5G NR) for future mobile communication systems. In the 5G NR system, Semi-Persistent Scheduling (Semi-Persistent Scheduling, SPS) Physical Downlink Shared Channel (PDSCH) transmission is supported. When the SPS PDSCH is configured for a terminal, it is necessary to configure the transmission interval and the configured scheduling (configured scheduling, CS) Cell Radio Network Temporary Identifier (C-RNTI) for the SPS PDSCH. The CS C-RNTI is used to identify Corresponding to the Physical Downlink Control Channel (PDCCH) of the SPS service, such as the PDCCH indicating the a...
