Coding and multiplexing of control information in a wireless communications system

Title:

Coding and multiplexing of control information in a wireless communications system

Document Type and Number:

Japanese Patent JP6181227

Kind Code:

B2

Abstract:

A method and corresponding apparatus for sending control information in a wireless communication system are described, the method comprising spreading control information across frequency with a discrete Fourier transform to obtain frequency spread data and spreading the frequency spread data across time with an orthogonal sequence to obtain output data for the control information. Also the corresponding method and apparatus for receiving control information are described.
