METHOD AND APPARATUS FOR TRANSMITTING UPLINK CONTROL INFORMATION FOR CARRIER AGGREGATED SPECTRUMS
First Claim
1. A method for transmitting uplink control information (UCI) in carrier aggregated spectrums, comprising:
- receiving configuration information regarding downlink component carriers and at least one uplink component carrier;
associating the downlink component carriers and the at least one uplink component carrier; and
combining UCI in accordance with the configuration information for transmission over the at least one uplink component carrier.

Abstract
Methods and apparatus for transmitting uplink control information (UCI) in carrier aggregated spectrums are disclosed. UCI may include, but is not limited to, Precoding Matrix Indicator (PMI), Rank Indication (RI), Channel Quality Indicator (CQI), Acknowledge/Not Acknowledge (ACK/NACK) and Scheduling Request (SR). For symmetric carrier aggregation, uplink (UL) and downlink (DL) component carriers may be paired and use physical uplink control channel (PUCCH) in each UL component carrier to send UCI for the corresponding DL component carrier. For asymmetric carrier aggregation, methods are provided for UCI transmission and resource allocation depending on component carrier configuration or assignment. Methods are provided for multiple and single component carrier configurations that may further provide backward compatibility.
