It should be noted that when the N pieces of DCI are sorted in the preset order, one of the orders may be selected as a reference to sort the N pieces of DCI, for example, the N pieces of DCI are sorted by using a high priority as a reference. Optionally, usually, a priority is preferably selected as a reference for sorting. If no priority is labeled for the user equipment, latency sensitivity is selected as a reference for sorting. If latency sensitivity cannot be determined, a channel condition is used as a reference for sorting.
When the preset order includes at least two orders, the at least two orders may be sorted and selected based on importance. For example, importance of a priority is greater than importance of latency sensitivity, and the importance of latency sensitivity is greater than importance of a channel condition. When the N pieces of DCI are being sorted, the N pieces of DCI may be first sorted based on priorities of user equipments of the N pieces of DCI; if user equipments of two or more pieces of DCI have a same priority, latency sensitivity of the user equipments of the two or more pieces of DCI is considered, and DCI of latency-sensitive user equipment ranks higher; and if user equipment of two or more pieces of DCI have same latency sensitivity, channel conditions of the user equipment of the two or more pieces of DCI are then considered, and DCI of user equipment in a good channel condition ranks higher.
