Claim 6:
7. A system comprising a terminal and a base station, wherein
the terminal comprises:
a receiver that receives a medium access control control element (MAC CE); and
a processor that controls, based on a number of transmission configuration indication (TCI) states corresponding to a certain TCI codepoint, among a plurality of TCI codepoints configured by the MAC CE, to perform either a single transmission/reception point (TRP) operation or a multi-TRP operation,
wherein when performing the single TRP operation, the processor determines a number of code division multiplexing (CDM) groups and DMRS ports based on a first DMRS table, and when performing the multi-TRP operation, the processor determines a number of CDM groups and DMRS ports based on a second DMRS table that differs from the first DMRS table, and

the base station comprises:
a transmitter that transmits the MAC CE.
