1. A wireless communication method, comprising:
transmitting, by a base station, multicast channel data to a terminal according to a multicast search space;
wherein the multicast search space comprises a first-type multicast common search space, a second-type multicast common search space and a third-type multicast common search space, wherein the first-type multicast common search space is configured for transmitting first-type multicast downlink control information comprising scheduling information of multicast control channel data, the second-type multicast common search space is configured for transmitting second-type multicast downlink control information comprising scheduling information of multicast traffic channel data, and the third-type multicast common search space is configured for transmitting third-type multicast downlink control information comprising multicast control channel change notification information,
wherein a size of the first-type multicast downlink control information corresponding to the first-type multicast common search space, a size of the second-type multicast downlink control information corresponding to the second-type multicast common search space, and a size of the third-type multicast downlink control information corresponding to the third-type multicast common search space are same.
