The method for sending a grant signalling includes: configuring one Multi-Physical Downlink Control Channel (M-PDCCH); and sending a grant signalling to N pieces of User Equipment (UE) through the M-PDCCH. By the technical solution, the technical problem that data throughput and spectral efficiency of a system are reduced by higher PDCCH overhead caused by the fact that one PDCCH or EPDCCH signalling can be granted to only one piece of UE in the related technology is solved, and the technical effect of improving the data throughput and spectral efficiency of the system is achieved.
