## Abstract

A terminal apparatus includes a coding unit configured to map coded bits for an uplink shared channel (UL-SCH) and a first sequence to a set of elements, and a transmitter configured to transmit a physical uplink shared channel (PUSCH), wherein each of the elements is identified by a subcarrier index of the PUSCH and an OFDM symbol index of the PUSCH, and whether the first sequence is mapped without using a prescribed set of elements is given based on at least the number of hybrid automatic repeat request HARQ-ACK bits mapped to the PUSCH.

## Claims

### Claim 1

A terminal device comprising:
coding circuitry configured to map a first sequence for an uplink shared channel (UL-SCH), a second sequence for first channel state information (CSI), and a third sequence for second CSI to a set of elements; and
transmission circuitry configured to transmit a physical uplink shared channel (PUSCH), wherein
each of the elements is identified by a subcarrier index for the PUSCH and an orthogonal frequency division multiplexing (OFDM) symbol index for the PUSCH,
the first sequence is mapped to a first predetermined set of elements,
the second sequence is mapped to a second predetermined set of elements avoiding the first predetermined set of elements where the mapping of the second sequence is given at least based on the first predetermined set of elements, and
the third sequence is mapped to the first predetermined set of elements.

### Claim 2

A communication method for a terminal device, the communication method comprising:
mapping a first sequence for an uplink shared channel (UL-SCH), a second sequence for first channel state information (C SI), and a third sequence for second CSI to a set of elements; and
transmitting a physical uplink shared channel (PUSCH), wherein
each of the elements is identified by a subcarrier index for the PUSCH and an orthogonal frequency division multiplexing (OFDM) symbol index for the PUSCH,
the first sequence is mapped to a first predetermined set of elements,
the second sequence is mapped to a second predetermined set of elements avoiding the first predetermined set of elements where the mapping of the second sequence is given at least based on the first predetermined set of elements, and
the third sequence is mapped to the first predetermined set of elements.
