Terminal apparatus, base-station apparatus, communication system, and communication method

A base-station apparatus configured to communicate with a terminal apparatus, the base-station apparatus comprising:

• transmitting circuitry configured to transmit control information used for a scheduling of a Physical Uplink Shared Channel (PUSCH);
• and
• receiving circuitry configured to receive partial precoder information that specifies at least one preferred candidate from among a plurality of candidates of precoders, the partial precoder information being reported together with data from the terminal apparatus on the PUSCH, wherein
• modulation symbols of the partial precoder information and modulation symbols of the data are interleaved jointly in a case that the partial precoder information is aperiodically reported, and
• modulation symbols of the partial precoder information and modulation symbols of the data are interleaved separately in a case that the partial precoder information is periodically reported.

A communication method of a terminal apparatus configured to communicate with a base-station apparatus, the communication method comprising:

• receiving control information used for a scheduling of a physical Uplink Shared Channel (PUSCH);
• and
• reporting partial precoder information that specifies at least one preferred candidate from among a plurality of candidates of precoders, the partial precoder information being reported together with data from the terminal apparatus on the PUSCH, wherein
• in a case that the partial precoder information is to be aperiodically reported, modulation symbols of the partial precoder information and modulation symbols of the data are interleaved jointly;
• and
• in a case that the partial precoder information is to be periodically reported, modulation symbols of the partial precoder information and modulation symbols of the data are interleaved separately.
