a processor; and

a memory storing instructions executable by the processor;

wherein when the instructions are executed by the processor, the terminal device is caused to:

in a case where Network Control Small Gap (NCSG) is supported, send first indication information to a network device;

wherein the first indication information is used to indicate NCSG configuration information supported by the terminal device;

wherein the first indication information sent by the terminal device comprises a first bit string;

wherein the first bit string comprises N bits, each of the N bits corresponds to at least one piece of NCSG configuration information, and NCSG configuration information corresponding to different bits in the N bits is different;

wherein in a case where a value of an i-th bit among the N bits is a first value, the i-th bit is used to indicate that the terminal device supports at least one piece of NCSG configuration information corresponding to the i-th bit, where N is a positive integer, and i is a positive integer less than or equal to N.
