1. A method for transmitting downlink control information, the method comprising:
determining, by a network side device, an aggregation level of a first physical control channel set and an aggregation level of a second physical control channel set in a transmission subframe;
determining, by the network side device, a number of physical control channel candidates corresponding to the aggregation level of the first physical control channel set;
determining, by the network side device, a number of physical control channel candidates corresponding to the aggregation level of the second physical control channel set; and
sending, by the network side device, downlink control information on at least one of: at least one physical control channel candidate corresponding to the number of the physical control channel candidates of the first physical control channel set and at least one physical control channel candidate corresponding to the number of the physical control channel candidates of the second physical control channel set;
wherein when the aggregation level of the first physical channel set and the aggregation level of the second physical channel set are 4, a sum of the number of the physical control channel candidates of the first physical control channel set and the number of the physical control candidates of the second physical control channel set is 6.
