Methods for receiving and sending downlink control information, user equipment, and base station

A method for sending downlink control information, comprising:

• scrambling first downlink control information based on a preset radio network temporary identifier (RNTI), a type of the preset RNTI being identical with a type of an RNTI used by a base station to scramble short downlink control information (sDCI), the first downlink control information comprising time-frequency position indication information and repeat count indication information;
• and
• sending the scrambled first downlink control information to user equipment (UE) through a first subslot;
• wherein the time-frequency position indication information is configured to indicate a time-frequency position of a downlink resource bearing target communication data in the first subslot, and the repeat count indication information is configured to indicate a count of repeated transmissions of the target communication data by the base station.

User equipment, comprising:

• a processor;
• and
• a memory for storing instructions executable by the processor;
• wherein the processor is configured to:
• receive first downlink control information sent by a base station through a first subslot, the first downlink control information comprising time-frequency position indication information and repeat count indication information, wherein the time-frequency position indication information is configured to indicate a time-frequency position of a downlink resource bearing target communication data in the first subslot, and the repeat count indication information is configured to indicate a count of repeated transmissions of the target communication data by the base station, wherein the count of repeated transmissions indicated by the repeat count indication information is n;
• determine n second subslots according to the count n indicated by the repeat count indication information and a preset time-frequency position determination rule, the n second subslots being subslots through which the base station repeatedly sends the target communication data;
• and
• not execute an operation of receiving second downlink control information in the n second subslots, a type of the second downlink control information being identical with a type of the first downlink control information.

A base station, comprising:

• a processor;
• and
• a memory for storing instructions executable by the processor;
• wherein the processor is configured to:
• scramble first downlink control information based on a preset radio network temporary identifier (RNTI), a type of the preset RNTI being identical with a type of an RNTI used by the base station to scramble short downlink control information (sDCI), the first downlink control information comprising time-frequency position indication information and repeat count indication information;
• and
• send the scrambled first downlink control information to user equipment (UE) through a first subslot;
• wherein the time-frequency position indication information is configured to indicate a time-frequency position of a downlink resource bearing target communication data in the first subslot, and the repeat count indication information is configured to indicate a count of repeated transmissions of the target communication data by the base station.
