1. An information indicating method, comprising:
sending, by a terminal device, indication information to a network device, wherein the indication information is used to indicate additional spectrum emission supported by the terminal device;
wherein the sending, by a terminal device, indication information to a network device comprises:
sending, by the terminal device, third indication information to the network device, wherein there are k bits that are multiplexed in the third indication information, the k bits are bits used to indicate the additional spectrum emission supported by the terminal device, and K is a positive integer;
wherein the k bits that are multiplexed in the third indication information comprise:
a first bit in a modified maximum power reduction (MPR) behavior signaling, wherein the first bit is used to indicate a bit used to indicate a modified maximum power reduction (MPR) behavior;
or, all or part of reserved bits in the modified maximum power reduction (MPR) behavior signaling, wherein the reserved bits are bits other than the first bit;
or, the first bit and all or part of the reserved bits in the modified maximum power reduction (MPR) behavior signaling.
