Description

Transmission Direction Setting Method, User Equipment, Network Device This application claims the preferential benefit of U.S. provisional application 63/336,229 filed on April 28, 2018. The entirety of the aforementioned patent application is incorporated herein by reference and forms part of this specification. The present invention generally relates to a transmission direction setting method, user equipment, and network device. In Time Division Duplex (TDD), time domain resources can be allocated for downlink or uplink transmission. However, in TDD, allocating limited time to the uplink reduces coverage and increases latency. For example, FIG. 1 is a schematic diagram illustrating an example of latency. Referring to FIG. 1, "D" represents downlink (DL) and "U" represents uplink (UL). Transmission directions for multiple time slots are set as in FIG. 1. That is, a complete serving cell is allocated to a single transmission direction within a single time slot. When the PDSCH (Physical Downlink Shared Channel) is transmitted, the base station waits for three time slots and then receives HARQ (Hybrid Automatic Repeat Request) feedback on the PUCCH (Physical Uplink Control Channel). In addition, if UL data is to be transmitted, the base station must schedule UL resources for UL data by downlink control information (DCI), and in this case, the UL resources must be separated for a duration four times the time slot in which the DCI is scheduled.
