Abstract
To enable a base station to select a more preferable codebook, a device includes a communication unit configured to perform radio communication and a control unit configured to perform control such that information regarding a codebook for multi-dimensionally modulating input data into a codeword is transmitted from the communication unit to a base station.
Claims20
A device comprising:
- storage circuitry configured to store codebook information;
- antenna circuitry configured to transmit radio waves in accordance to signals directed from processing circuitry, and configured to convert radio waves to signals directed to the processing circuitry;
- the processing circuitry configured to perform radio communications;
- and
- the processing circuitry configured to perform control such that information regarding a preferred codebook for multi-dimensionally modulating input data into a codeword is transmitted from the processing circuitry to a base station;
- wherein the processing circuitry is configured to transmit the information after successive receipt, from the base station to the device, of a request for codebook indication and a Sparse Code Multiple Access Reference Signal (SCMA-RS);
- wherein the request for codebook indication included a resource block to be used during reception of the SCMA-RS;
- wherein the SCMA-RS was received in a user data region;
- and
- the processing circuitry is configured to perform the radio communications in accordance with the preferred codebook.
