Abstract

A terminal according to one aspect of the present disclosure is characterized by including: a transmission unit that uses a physical uplink shared channel (PUSCH) to transmit a plurality of transport blocks to a transmission / reception point (TRP); and a control unit that determines a parameter relating to an initial value for generating a scramble sequence to be applied to the PUSCH. According to this one aspect of the present disclosure, it is possible to appropriately perform PUSCH transmission.

Claims

1. A transmitter that reports the ability to support uplink (UL) transmission of eight antenna ports and transmits multiple codewords using a Physical Uplink Shared Channel (PUSCH), A terminal having a control unit that uses different initial values ​​defined for each index of the codeword in order to generate a scramble sequence to be applied to the PUSCH.

2. The terminal according to claim 1, wherein the control unit multiplexes Uplink Control Information (UCI) into one of the plurality of codewords when transmitting the PUSCH.

3. The step of reporting the ability to support uplink (UL) transmission of eight antenna ports, The steps include sending multiple codewords using the Physical Uplink Shared Channel (PUSCH), A wireless communication method for a terminal, comprising the step of using different initial values ​​defined for each index of the codeword in order to generate a scramble sequence to be applied to the PUSCH.

4. A receiving unit that receives a report on the ability of eight antenna ports to support uplink (UL) transmission and receives a plurality of codewords using a Physical Uplink Shared Channel (PUSCH), A base station having a control unit that controls the reception of the PUSCH transmitted from a terminal using different initial values ​​defined for each index of the codeword, in order to generate a scramble sequence to be applied to the PUSCH.

5. A system comprising a terminal and a base station, The aforementioned terminal is The report describes the capability to support uplink (UL) transmission with eight antenna ports, and the transmitter unit that transmits multiple codewords using a Physical Uplink Shared Channel (PUSCH), The system includes a control unit that uses different initial values ​​defined for each index of the codeword in order to generate a scramble sequence to be applied to the PUSCH, The base station is a system having a receiving unit that receives reports regarding the capability and the PUSCH.
