METHOD AND APPARATUS FOR TRANSMITTING/RECEIVING CHANNEL STATE INFORMATION
First Claim
1. A method for transmitting Channel State Information (CSI) report in a wireless network where a plurality of cells is configured to cooperate for a User Equipment (UE) with Carrier aggregation (CA), the method comprising:
- detecting a collision in a subframe, between a first Physical Uplink Control Channel (PUCCH) CSI report of one serving cell with which the UE is configured in one of transmission modes 1 to 9, and a second PUCCH CSI report of another serving cell with which the UE is configured in transmission mode 10;
comparing the priorities of reporting types of the collided PUCCH CSI reports; and
upon the reporting types of the collided PUCCH CSI reports having a same priority, transmitting the first PUCCH CSI report if a CSI process index of the second PUCCH CSI report has a positive value other than 1.

Abstract
A method for CSI report transmission includes detecting a collision in a subframe, between a first PUCCH CSI report of one serving cell with which a UE is configured in one of transmission modes 1 to 9, and a second PUCCH CSI report of another serving cell with which the UE is configured in transmission mode 10. Upon the reporting types of the collided PUCCH CSI reports having a same priority, the method transmits the first PUCCH CSI report if the CSI process index of the second PUCCH CSI report has a positive value other than 1. A method for CSI report transmission includes configuring, via a higher layer, a UE configured in transmission mode 10 whether to create a respective CSI report(s) for each aperiodic CSI process or not, using an information element including at least three one-bit variables.
