The method and system for directing the transmission mode for uplink control information

Title:

The method and system for directing the transmission mode for uplink control information

Document Type and Number:

Japanese Patent JP5934399

Kind Code:

B2

Abstract:

A method for Uplink Control Information (UCI) transmission of User Equipment (UE) in a communication system is disclosed. The method comprises receiving information indicating whether simultaneous Physical Uplink Shared Channel (PUSCH) and Physical Uplink Control Channel (PUCCH) transmission is configured or not. The method further comprises identifying whether at least one PUSCH transmission is configured at a corresponding subframe for UCI transmission or not. The method further comprises transmitting, when at least one PUSCH transmission configured at the corresponding subframe for UCI transmission, the UCI on a PUSCH at the corresponding subframe. The method further comprises transmitting, when the UE is configured with more than one serving cell and is not configured for simultaneous PUSCH and PUCCH transmission, the UCI on PUSCH of a serving cell at the corresponding subframe if the UCI consists of aperiodic Channel Status Information (CSI) or aperiodic CSI and Hybrid Automatic Repeat Request (HARQ) with-Acknowledgement (ACK).
