Description

Scheduling method, device, base station, terminal and medium for data transmission Technical Field The present invention relates to the field of communications technologies, and in particular, to a scheduling method, an apparatus, a base station, a terminal, and a medium for data transmission. Background Current NR (New Radio) systems support scheduling multiple physical shared channels for data transmission at a single time. NR-U standardizes scheduling a plurality of PUSCHs (Physical Uplink SHARED CHANNEL, physical Uplink shared channels) at a time, and a high-level configuration TDRA (Time Domain Resource Allocation ) table, where each row of the table represents one single or a plurality of PUSCH time domain allocation information allocated continuously, and each row can be allocated with 8 PUSCHs at most. The NR Rel-17 high frequency issue standardizes the design scheme of Multi-PDSCH (Physical Downlink SHARED CHANNEL )/PUSCH scheduling, and one DCI (Downlink Control Information ) can schedule 8 PDSCH/PUSCH at most, supports discontinuous time domain scheduling, and can span uplink timeslots/symbols in TDD system. However, SCS (Subcarrier Spacing ) applicable to FR1 and FR2-1 is smaller, when one DCI schedules PDSCH of a plurality of slots, the span between the scheduled time instants to the actual transmission is longer, and due to the time-varying nature of the channel, the resource configuration of PDSCH whose time domain position is far from the scheduled DCI may not match the channel state at the transmission time, for example, MCS level is too high or too low, resulting in high error rate or low resource utilization.
