A network side device, comprising:

• a processor;
• and a memory having a computer program or an instruction stored thereon, wherein the computer program or the instruction, when executed by the processor, causes the processor to implement operations, comprising:
• sending a Media Access Control Control Element (MAC CE) command, wherein the MAC CE command comprises at least two first MAC CE commands or a second MAC CE command,
• wherein:
• the first MAC CE command is used to activate a Transmission Configuration Indicator (TCI) state corresponding to one piece of first identifier information,
• the second MAC CE command is used to activate TCI states corresponding to at least two pieces of second identifier information, and
• an activated TCI state is used to determine common beam information of a plurality of channels.
