Method and device for performing repetition transmission to improve uplink quality

A terminal device, comprising:

• circuitry configured to:
• receive repetition setting information, wherein
• the repetition setting information includes
• repetition information that indicates repetition transmission of a signal in an uplink, and
• beam information that is associated with the repetition information,
• the beam information indicates a plurality of beams,
• the plurality of beams includes a first beam, and a second beam different from the first beam, and
• the repetition setting information further includes a ratio of a number of repetitions of the signal in the first beam and a number of repetitions of the signal in the second beam;
• and
• perform the repetition transmission of the signal in a plurality of slots based on the repetition setting information, wherein the repetition transmission of the signal is in each of the first beam and the second beam.
