However, the above words are not to be construed as limiting the scope of the invention.

According to the CBGTI indication method applied to the network equipment, the DCI comprises the indication information used for indicating the mapping relation between the CBGTI indication information and the N physical channels, the mapping relation between the CBGTI indication information and the N physical channels can be accurately indicated, and the signaling overhead is low.

In one embodiment of the invention, the number of sets of mappings is determined based on Mmax and Nmax. Wherein, Mmax is the maximum number of CBGTI indication information items that can be indicated in DCI, and Nmax is the maximum number of schedulable physical channels of DCI.

In one embodiment of the invention, Mmax and Nmax may be specified by a protocol or configured by higher layer signaling.

In one embodiment of the invention, the number of sets of mapping relationships may be
