Title:
METHOD AND APPARATUS FOR TRANSMITTING CHANNEL STATE INFORMATION USING PUCCH FORMAT 3 IN A WIRELESS ACCESS SYSTEM
Document Type and Number:
WIPO Patent Application WO/2013/048109
Kind Code:
A2
Abstract:
The present invention relates to various apparatuses and methods for encoding Channel State Information (CSI) and transmitting the encoded CSI in a wireless access system supporting a multi-cell or multi-carrier environment. The method for user equipment to transmit CSI about two or more cells in a wireless access system includes the steps of: generating CSI bits for two or more cells; encoding each CSI bit for the two or more cells; and periodically transmitting the encoded CSI bit using physical uplink control channel (PUCCH) format 3.
