Downlink control channel detection method, terminal and base station

A terminal, comprising a processor, a memory, and a computer program stored in the memory, wherein the computer program is executable by the processor, when the computer program is executed by the processor, the processor is caused to perform:

• obtaining first auxiliary information and second auxiliary information, wherein the first auxiliary information indicates a time-domain duration of a control resource set of a downlink control channel, which is allocated by a base station, the second auxiliary information indicates a resource mapping mode from a resource element group (REG) of the control resource set to a control channel elements (CCE);
• and,
• performing a blind detection on the downlink control channel, based on the first auxiliary information and the second auxiliary information;
• wherein performing the blind detection on the downlink control channel, based on the first auxiliary information and the second auxiliary information, comprises:
• determining a blind-detection priority of each control resource set of the downlink control channel, based on the first auxiliary information and the second auxiliary information;
• and,
• performing the blind detection on the downlink control channel, based on the blind-detection priority of each control resource set;
• wherein determining the blind-detection priority of each control resource set of the downlink control channel, based on the first auxiliary information and the second auxiliary information, comprises:
• when N indicated by the first auxiliary information is greater than or equal to a fourth index M4, determining that the blind-detection priority of the control resource set of the downlink control channel is a high priority;
• when N indicated by the first auxiliary information is less than M4, determining that the blind-detection priority of the control resource set of the downlink control channel is a low priority, wherein N is the quantity of time-domain symbols occupied by the control resource set, M4 is an index of the last OFDM symbol in a pre-allocated control resource set, which is pre-allocated by the base station, indexes of the OFDM symbols in the pre-allocated control resource set start from 1, M4 and N are both integers.
