摘要

When transmitting retransmission data, MCS information of a control channel for when communicating the new data is replaced with retransmission control information and the control channel is transmitted. When receiving retransmission data, the control channel is received to obtain the retransmission control information, the replaced MCS information is estimated from the control channel received at the time of communication of new data, and a reception process of retransmission data is controlled using the estimated MCS information and the retransmission control information.

1. A wireless communication method comprising:
transmitting a first code block and a first control signal which specifies a modulation and a coding scheme applied to transmission of the first code block from among a first number of candidates for a modulation and coding scheme to be applied to new transmission; and retransmitting the first code block together with a second code block using a modulation and a coding scheme selected from a second number of candidates for a modulation and coding scheme to be applied to retransmission where the second number is less than the first number, while transmitting a second control signal that includes retransmission code block information but does not include scheme information for specifying the selected modulation and coding scheme.
