Abstract

The present invention provides a transmission method, a sending end device, a receiving end device and a network side device. The method includes: repeatedly transmitting N physical shared channels; said N is an integer greater than 1; in the time domain, any physical shared channel The transmission resources of the channel are continuously distributed in the time domain, and the transmission resources of any physical shared channel are located in the same time slot. In this way, when there is a conflict in the transmission direction during repeated transmission, the transmitting device can transmit according to the rule that the transmission resources of any physical shared channel must be continuously distributed in the time domain and located in the same time slot. The transmission conflict is effectively resolved, and the reliability of repeated transmission is improved.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to a transmission method, a sending end device, a receiving end device and a network side device. Background technique [0002] Compared with the existing 4G mobile communication system, the 5G mobile communication system can better meet the diverse scenarios and business needs of users. The 3rd Generation Partnership Project (3GPP) defines three directions for 5G application scenarios: eMBB (Enhanced Mobile Broadband), mMTC (Massive Machine Type Communication) and uRLLC (Ultra Reliable, Low Latency Communication). Among them, for the uRLLC service, in order to meet the requirements of low-latency and high-reliability service indicators, a physical downlink shared channel (Physical Downlink Shared Channel, PDSCH) / physical uplink shared channel ( Physical Uplink Shared Channel, PUSCH) for repeated transmission. [0003] However, there is currently no specific solu...
