METHOD FOR TRANSMITTING DOWNLINK CONTROL INFORMATION, NETWORK SIDE DEVICE AND USER EQUIPMENT

摘要

The present invention provides a method for transmitting downlink control information, a network side device and a user equipment. The method for transmitting downlink control information comprises: a network side device selecting an aggregation level to be detected of a physical control channel set in a transmission subframe, selecting the number of physical control channel candidates corresponding to the aggregation level according to the aggregation level, and the network side device sending downlink control information over physical control channel candidates corresponding to the selected number. The number of blind detection times corresponding to the aggregation level corresponds to the number of physical control channel candidates, and therefore after the number of physical control channel candidates is determined, the number of blind detection times is determined as well. The network side device and the user equipment can communicate without increasing the number of blind detection times.
