Embodiment Construction

[0080] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the following will gather the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0081]The 5G NR system supports SPS PDSCH transmission. When configuring SPS PDSCH (PDSCH without corresponding PDCCH) transmission for the terminal, it is necessary to configure the transmission interval and CS (configured scheduling) C-RNTI for the SPS PDSCH, where the CS C-RNTI is used to identify the PDCCH corresponding to the SPS se...

Abstract

The embodiment of the invention provides an HARQ-ACK transmission method for an SPS PDSCH, which comprises the following steps of: if the total amount of HARQ-ACK information of the SPS PDSCH needingto be transmitted at the current moment is greater than a second preset threshold value, transmitting HARQ-ACK by using a first PUCCH resource; otherwise, transmitting the HARQ-ACK by using the secondPUCCH resource corresponding to the SPS PDSCH, wherein the terminal corresponds to at least one first PUCCH resource used for transmitting HARQ-ACKs of a plurality of SPS PDSCHs, each SPS configuration corresponds to one second PUCCH resource, and each SPS PDSCH corresponds to one SPS configuration. According to the method provided by the embodiment of the invention, normal feedback during HARQ-ACK collision of a plurality of SPS PDSCHs is ensured.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a HARQ-ACK transmission method of SPS PDSCH. Background technique [0002] With the development and change of mobile communication service requirements, 5G NR (5Generation New RAT) wireless communication system came into being. The 5G NR system supports Semi-Persistent Scheduling (SPS, Semi-Persistent Scheduling) Physical Downlink Shared Channel (PDSCH, Physical Downlink Shared CHannel) transmission. [0003] When the terminal receives the SPS PDSCH, the terminal passes the physical uplink control channel (PUCCH, Physical Uplink Control CHannel ) / Physical Uplink Shared CHannel (PUSCH, Physical Uplink Shared CHannel) to send the HARQ-ACK of the SPS PDSCH to inform the base station whether the SPS PDSCH transmission is received correctly. [0004] In the 5G NR system, multiple SPS configurations can be configured for one terminal, and a shorter (for example...
