Abstract

Terminal device comprising: reception circuitry configured to receive a PDCCH scheduling a first PUSCH and a second PUSCH; and transmission circuitry configured to transmit the first PUSCH and/or the second PUSCH; and a number NPRB1 of PRBs is allocated to the first PUSCH and a number NPRB2 of PRBs which is different from the NPRB1 is allocated to the second PUSCH at least based on a FDRA field included in the PDCCH; wherein a size of a transport block is determined at least based on a baseline number NPRBbaseline of PRBs; and the NPRBbaseline is determined at least based on NPRB1 and NPRB2; and the transport block is included in the first PUSCH and the second PUSCH.

First claim

The invention claimed is:

1. A terminal device comprising:
reception circuitry configured to receive a Physical Downlink Control Channel (PDCCH) scheduling a first Physical Uplink Shared Channel (PUSCH) and a second PUSCH; and
transmission circuitry configured to transmit the first PUSCH and/or the second PUSCH, wherein:
a number N PRB 1 of Physical Resource Blocks (PRBs) is allocated to the first PUSCH and a number N PRB 2 of PRBs which is different from the N PRB 1 is allocated to the second PUSCH at least based on a Frequency Domain Resource Assignment (FDRA) field included in the PDCCH;
a size of a transport block is determined at least based on a baseline number N PRB baseline of PRBs;
the N PRB baseline is determined at least based on N PRB 1 and N PRB 2 ; and
the transport block is included in the first PUSCH and the second PUSCH.

2. The terminal device according to claim 1 , wherein:
N PRB baseline consecutive PRBs from the lowest frequency end or to the highest frequency end of the PRBs allocated to the first PUSCH are used for transmission of the first PUSCH; and
N PRB baseline consecutive PRBs from the lowest frequency end or to the highest frequency end of the PRBs allocated to the second PUSCH are used for transmission of the second PUSCH.

3. The terminal device according to claim 1 , wherein:
all the PRBs allocated to the first PUSCH are used for transmission of the first PUSCH; and
all the PRBs allocated to the second PUSCH are used for transmission of the second PUSCH.

4. A base station device comprising:
transmission circuitry configured to transmit a Physical Downlink Control Channel (PDCCH) scheduling a first Physical Uplink Shared Channel (PUSCH) and a second PUSCH; and
reception circuitry configured to receive the first PUSCH and/or the second PUSCH, wherein:
a number N PRB 1 of Physical Resource Blocks (PRBs) is allocated to the first PUSCH and a number N PRB 2 of PRBs which is different from the N PRB 1 is allocated to the second PUSCH at least based on a Frequency Domain Resource Assignment (FDRA) field included in the PDCCH;
a size of a transport block is determined at least based on a baseline number N PRB baseline of PRBs;
the N PRB baseline is determined at least based on N PRB 1 and N PRB 2 ; and
the transport block is included in the first PUSCH and the second PUSCH.

5. The base station device according to claim 4 , wherein:
N PRB baseline consecutive PRBs from the lowest frequency end or to the highest frequency end of the PRBs allocated to the first PUSCH are used for transmission of the first PUSCH; and
N PRB baseline consecutive PRBs from the lowest frequency end or to the highest frequency end of the PRBs allocated to the second PUSCH are used for transmission of the second PUSCH.

6. The base station device according to claim 4 , wherein:
all the PRBs allocated to the first PUSCH are used for transmission of the first PUSCH; and
all the PRBs allocated to the second PUSCH are used for transmission of the second PUSCH.

7. A communication method used by a terminal device, the communication method comprising:
receiving a Physical Downlink Control Channel (PDCCH) scheduling a first Physical Uplink Shared Channel (PUSCH) and a second PUSCH; and
transmitting the first PUSCH and/or the second PUSCH, wherein:
a number N PRB 1 of Physical Resource Blocks (PRBs) is allocated to the first PUSCH and a number N PRB 2 of PRBs which is different from the N PRB 1 is allocated to the second PUSCH at least based on a Frequency Domain Resource Assignment (FDRA) field included in the PDCCH;
a size of a transport block is determined at least based on a baseline number N PRB baseline of PRBs;
the N PRB baseline is determined at least based on N PRB 1 and N PRB 2 ; and
the transport block is included in the first PUSCH and the second PUSCH.
