ENCODING AND DECODING OF CONTROL INFORMATION FOR WIRELESS COMMUNICATION

Title:

ENCODING AND DECODING OF CONTROL INFORMATION FOR WIRELESS COMMUNICATION

Document Type and Number:

Japanese Patent JP2014075810

Kind Code:

A

Abstract:

To provide techniques for sending control information, such as CQI information and ACK information, in a wireless communication system.

User equipment (UE) maps first information (e.g., CQI information) to M most significant bits (MSBs) of a message and maps second information (e.g., ACK information) to N least significant bits (LSBs) of the message if the second information is sent, where M≥1 and N≥1. The UE encodes the message with a block code, encodes the M MSBs with the first M basis sequences of the block code and encodes the N LSBs with the next N basis sequences of the block code. The second information includes N ACK bits. The UE sets each of the N ACK bits to a first value for an ACK or to a second value for a NACK. The second value is also used for DTX of ACK information.
