|1. (WO2018059297) METHOD AND APPARATUS FOR TRANSMITTING PHYSICAL DOWNLINK CONTROL CHANNEL, AND BASE STATION AND TERMINAL|
|Title:||METHOD AND APPARATUS FOR TRANSMITTING PHYSICAL DOWNLINK CONTROL CHANNEL, AND BASE STATION AND TERMINAL|
Provided are a method and apparatus for transmitting a physical downlink control channel, and a base station and a terminal. The transmission method comprises: a first communication node, based on a set of candidate sending modes, determining a set of actual sending modes, wherein the set of candidate sending modes contains X sending modes, X being an integer greater than or equal to 1; and the set of actual sending modes contains Y sending modes, Y being an integer greater than or equal to 1 and not greater than X; and the first communication node, according to the set of actual sending modes, sending a physical downlink control channel to a second communication node. The present invention solves the technical problem in the relevant art that the success rate of a receiving end receiving the physical downlink control channel is relatively low.
