Abstract
A terminal according to one aspect of the present disclosure includes a control section that determines an 8-port partial-coherent precoder configured based on some precoders limited based on at least a rank, from among 4-port precoders, and a transmitting section that performs uplink transmission, based on the 8-port partial-coherent precoder. One aspect of the present disclosure allows UL transmission using more than 4 antenna ports to be appropriately controlled.

-6. (canceled)
A terminal comprising:
- a processor that determines an 8-port partial-coherent precoder configured based on some precoders of 4-port precoders, the some precoders being limited based on at least a rank;
- and
- a transmitter that performs an uplink transmission based on the 8-port partial-coherent precoder,
- wherein when a rank for the uplink transmission is 4 or 6, the some precoders are limited to two 4-port precoders with a same rank.
A radio communication method for a terminal, comprising:
- determining an 8-port partial-coherent precoder configured based on some precoders of 4-port precoders, the some precoders being limited based on at least a rank;
- and
- performing an uplink transmission based on the 8-port partial-coherent precoder,
- wherein when a rank for the uplink transmission is 4 or 6, the some precoders are limited to two 4-port precoders with a same rank.
A base station comprising:
- a transmitter that transmits, to a terminal, configuration information for causing the terminal to determine an 8-port partial-coherent precoder configured based on some precoders of 4-port precoders, the some precoders being limited based on at least a rank;
- and
- a receiver that receives an uplink transmission transmitted based on the 8-port partial-coherent precoder,
- wherein when a rank for the uplink transmission is 4 or 6, the some precoders are limited to two 4-port precoders with a same rank.
A system comprising a terminal and a base station, wherein
- the terminal comprises:
- a processor that determines an 8-port partial-coherent precoder configured based on some precoders of 4-port precoders, the some precoders being limited based on at least a rank;
- and
- a transmitter that performs an uplink transmission based on the 8-port partial-coherent precoder, and
- the base station comprises:
- a transmitter that transmits, to the terminal, configuration information for causing the terminal to determine the 8-port partial-coherent precoder;
- and
- a receiver that receives the uplink transmission,
- wherein when a rank for the uplink transmission is 4 or 6, the some precoders are limited to two 4-port precoders with a same rank.
