Description

technical field [0001] The present application relates to a transmission method and device in a wireless communication system, especially a wireless signal transmission method and device in a wireless communication system supporting a cellular network. Background technique [0002] In the 5G NR system, in order to support services with higher communication requirements such as eMBB (Enhance Mobile Broadband) and URLLC (Ultra Reliable and Low Latency Communication), it is different from the previous ones. Compared with a larger amount of DCI (Downlink Control Information, downlink control information) signaling needs to be sent to complete the transmission channel (such as, PDSCH (Physical Downlink SharedCHannel, physical downlink shared channel), PUSCH (Physical Uplink Shared CHannel) , Physical Uplink Shared Channel) etc.) scheduling (scheduling); this may bring potential system efficiency reduction. [0003] The 3GPP RAN plenary meeting passed a decision to conduct resear...
