A user terminal, a feedback method at the user terminal, a base station and a method at the base station

A user terminal, comprising:

• a communication apparatus configured to transmit and receive signals with a base station;
• a processor configured to
• calculate first information related to receiving signal quality;
• combine the first information and a response signal to a hybrid automatic repeat request (HARQ) to be transmitted to a base station to generate a combined signal;
• and
• carry out signal processing on the combined signal to generate second information;
• and
• a communication apparatus configured to transmit the second information to the base station.

A method at a base station, comprising steps of:

• receiving second information from a user terminal, wherein the second information is obtained by carrying out the following steps at the user terminal:
• calculating first information related to receiving signal quality;
• combining the first information and a response signal to a hybrid automatic repeat request (HARQ) to be received from the user terminal to generate a combined signal;
• carrying out signal processing on the combined signal to generate the second information.

A base station, comprising:

• a communication apparatus configured to receive second information from a user terminal, wherein the second information is obtained by carrying out the following steps at the user terminal:
• calculating first information related to receiving signal quality;
• combining the first information with a response signal to a hybrid automatic repeat request (HARQ) to be received from the user terminal to generate a combined signal;
