Multi-cell communication apparatus and method using rate-splitting scheme and transmission frame

A terminal in a multi-cell environment, the terminal comprising:

• a receiving unit configured to receive MAP information, the MAP information comprising an indicator configured to indicate a rate-splitting mode, the rate-splitting mode configured to set a base station to use a rate-splitting scheme from among a target base station and a neighbor base station;
• and
• a decoder configured to decode, based on the MAP information, at least one message transmitted from each of the target base station and the neighbor base station.

A communication method in a multi-cell environment, the method comprising:

• setting a rate-splitting mode based on channel information of a target base station and channel information of a neighbor base station, the rate-splitting mode setting a base station to use a rate-splitting scheme from among the target base station and the neighbor base station;
• and
• allocating, based on the rate-splitting mode, a power or a bandwidth to at least one message.
