Abstract: The present invention provides a method for transmitting downlink control information, a network side device, and a user equipment. The method includes: selecting, by a network side device, a aggregation level of a physical control channel set in a transmission subframe, and selecting the number of physical control channel candidates corresponding to the aggregation level according to the aggregation level; and sending, by the network side, downlink control information on a physical control channel candidate corresponding to the selected number. The times that blind detection is performed corresponding to the aggregation level corresponds to the number of physical control channel candidates, and therefore, when the number of physical control channel candidates is determined, the times that blind detection is performed is determined, so that the network side device and the user equipment can communicate with each other without increasing the times that blind detection is performed.

Abstract: This application provides a data sending method and apparatus. The method includes: A node generates a first modulation symbol corresponding to a first modulation scheme. The node quantizes the first modulation symbol to obtain a target symbol. The target symbol corresponds to one of a plurality of constellation points of a second modulation scheme. The node preprocesses the target symbol to obtain to-be-sent data. The preprocessing includes one or more of layer mapping, antenna port mapping, precoding, or transform precoding. The node maps the to-be-sent data to a physical resource, and sends the to-be-sent data by using the physical resource.
