Blind Detection Method and Apparatus

An apparatus, comprising:

• a processor and a memory storing instructions;
• wherein the instructions are executed by the processor to cause the apparatus perform operations of:
• receiving first indication information from a network side device;
• and
• determining N time units based on the first indication information, and determining, by the terminal side device, a time unit in the N time units corresponding to a type of terminal operation which is not to perform a first operation, a second operation and a third operation in the time unit in the N time units;
• wherein the N time units belong to a same transmission time unit, and each one of the N time units comprises at least one symbol, wherein N is an integer greater than 0;
• and
• the first operation is used to determine a quantity of blind detections to be performed on a physical downlink control channel, PDCCH, in a current time unit, the second operation is used to determine a quantity of non-overlapping control channel elements, CCEs, used for channel estimation on the PDCCH in the current time unit, and the third operation is used to determine whether the quantity of blind detections to be performed on the PDCCH in the current time unit is greater than a maximum quantity of blind detections that corresponds to the current time unit, and/or determines whether the quantity of non-overlapping CCEs in the current time unit is greater than a maximum quantity of CCEs that corresponds to the current time unit.
