Time slot scheduling method and device, and medium

A time slot scheduling method based on Downlink Control Information (DCI), comprising:

• receiving, by a terminal, a first corresponding relationship configured by a network side device via high-level signaling between scheduling information groups and scheduling information group indexes;
• receiving, by the terminal, a scheduling information group index sent by the network side device via one DCI;
• and determining, by the terminal, at least one scheduling information group indicated by the scheduling information group index;
• wherein the scheduling information group index is a scheduling information group index, corresponding to at least one scheduling information group, determined by the network side device according to the first corresponding relationship, and the at least one scheduling information group is selected by the network side device from a plurality of scheduling information groups configured for the terminal;
• wherein the scheduling information group index is determined according to a quantity of scheduling information groups configured for the terminal by the network side device;
• wherein the scheduling information groups in the first corresponding relationship configured for the terminal by the network side device through high- level signaling comprises:
• a scheduling information group containing all scheduling information;
• and a scheduling information group containing part of the scheduling information;
• wherein the scheduling information comprises time domain resource distribution information;
• the DCI is configured to schedule data transmission in a plurality of time slots, and the scheduling information at least indicates time domain resource distribution information used by the terminal in each of the plurality of time slots;
• wherein the scheduling information group index is sent by the network side device, corresponding to a time slot through a scheduling indication information domain, in the one DCI, corresponding to the time slot;
• and the scheduling indication information domain is determined by the network side device according to a position index, in the one DCI, of the scheduling indication information domain corresponding to the time slot needing to be scheduled in a second corresponding relationship between position indexes of scheduling indication information domains in the one DCI and time slots;
• and
• carrying out, by the terminal, data transmission in the plurality of time slots by using the at least one scheduling information group.

A device for time slot scheduling based on Downlink Control Information (DCI), comprising a processor, a memory and a transceiver;

• wherein the processor is configured to read a program in the memory and execute:
• configuring a first corresponding relationship between scheduling information groups and scheduling information group indexes for a terminal through high-level signaling;
• selecting, from a plurality of scheduling information groups configured for the terminal, at least one scheduling information group to be used by the terminal;
• determining a scheduling information group index corresponding to the at least one scheduling information group to be used by the terminal according to the first corresponding relationship;
• configuring a second corresponding relationship between position indexes of scheduling indication information domains in one DCI and time slots for the terminal through high-level signaling;
• determining a position index, in the one DCI, of a scheduling indication information domain corresponding to a time slot needing to be scheduled according to the second corresponding relationship;
• and
• sending a scheduling information group index corresponding to the time slot to the terminal through the corresponding scheduling indication information domain in the one DCI according to the position index;
• wherein the scheduling information group indexes are determined according to a quantity of the scheduling information groups configured for the terminal by the network side device;
• wherein the scheduling information groups in the first corresponding relationship configured for the terminal by the network side device through high-level signaling comprises:
• a scheduling information group containing all scheduling information;
• and
• a scheduling information group containing part of the scheduling information;
• wherein the scheduling information comprises time domain resource distribution information;
• the DCI is configured to schedule data transmission in a plurality of time slots, and the scheduling information at least indicates time domain resource distribution information used by the terminal in each of the plurality of time slots.
