Methods for communication, terminal device, network device, and computer readable medium

A method performed by a network device, comprising:

• transmitting a higher layer configuration indicating one repetition scheme among a first frequency division multiplexing (FDM) scheme, a second FDM scheme and a time division multiplexing (TDM) scheme;
• and
• in response to indicating to a terminal device, two transmission configuration indication (TCI) states and at least one DMRS port within one DMRS group:
• transmitting a downlink transmission of a Transport Block (TB) in a case where the TCI states are indicated and the first FDM scheme is indicated, wherein each of the two TCI states is associated with a non-overlapping frequency domain resource allocation;
• transmitting two downlink transmissions of a same TB in a case where the TCI states are indicated and the second FDM scheme is indicated, wherein each of the two TCI states is associated with a downlink transmission from the two downlink transmissions, and the downlink transmission is associated with a non-overlapping frequency domain resource allocation with respect to the other downlink transmission;
• or
• transmitting two downlink transmissions of a same TB within a single slot in a case where the two TCI states are indicated and the TDM scheme is indicated, wherein each of the two TCI states is associated with a downlink transmission from the two downlink transmissions, and the downlink transmission is associated with a non-overlapping time domain resource allocation with respect to the other downlink transmission.

A terminal device comprising:

• a receiver;
• and
• a processor configured to:
• receive a higher layer configuration indicating one repetition scheme among a first frequency division multiplexing (FDM) scheme, a second FDM scheme and a time division multiplexing (TDM) scheme;
• and
• in response to being indicated with two transmission configuration indication (TCI) states and at least one DMRS port within one DMRS group:
• receive a downlink transmission of a Transport Block (TB) in a case where the two TCI states are indicated and the first FDM scheme is indicated, wherein each of the two TCI states is associated with a non-overlapping frequency domain resource allocation;
• receive two downlink transmissions of a same TB in a case where the two TCI states are indicated and the second FDM scheme is indicated, wherein each of the two TCI states is associated with a downlink transmission from the two downlink transmissions, and the downlink transmission is associated with a non-overlapping frequency domain resource allocation with respect to the other downlink transmission;
• or
• receive two downlink transmissions of a same TB within a single slot in a case where the two TCI states are indicated and the TDM scheme is indicated, wherein each of the two TCI states is associated with a downlink transmission from the two downlink transmissions, and the downlink transmission is associated with a non-overlapping time domain resource allocation with respect to the other downlink transmission.
