Simultaneous transmission of different types of feedback information in a wireless environment

A device for supporting concurrent transmission of a Channel State Information (CSI) and a Hybrid Automatic Repeat reQuest Acknowledgment (HARQ-ACK) information, comprising:

• a modulation module operating at a User Equipment (UE), the modulation module configured to:
• modulate the CSI to assist in separating the CSI from the HARQ-ACK information data at an evolved Node B (eNodeB), and
• modulate the HARQ-ACK information data to assist in separating the HARQ-ACK information from the CSI at the eNodeB;
• a processing module configured to process combined data comprising the CSI and the HARQ-ACK information data for transmission;
• and
• a transmission module configured to transmit the combined data.

A computer program product for supporting concurrent transmission of a Channel State Information (CSI) and a Hybrid Automatic Repeat reQuest Acknowledgment (HARQ-ACK) information, comprising a non-transitory computer usable medium having a computer readable program code embodied therein, the computer readable program code adapted to be executed at a User Equipment (UE) to implement a method for concurrent transmission of the CSI and the HARQ-ACK information, comprising:

• modulating the CSI according to a predetermined regime, and
• modulating the HARQ-ACK information according to the predetermined regime, wherein the predetermined regime is configured to allow the CSI and the HARQ-ACK information to be separated after the CSI and the HARQ-ACK information have been combined;
• combining the CSI and the HARQ-ACK information to form a combined signal;
• and
• transmitting the combined signal.

A method for supporting concurrent transmission of a CSI and a Hybrid Automatic Repeat reQuest Acknowledgment (HARQ-ACK) information from a User Equipment (UE), comprising:

• determining, at the UE, a combined payload associated with the CSI and the HARQ-ACK information is smaller than a predefined payload value;
• determining, at the UE, a ratio defined by a CSI payload associated with the CSI over a HARQ-ACK payload associated with the HARQ-ACK information is smaller than a predefined ratio value;
• concatenating, at the UE, the CSI with the HARQ-ACK information according to a predefined concatenation scheme to produce a concatenated unit of data;
• and
• transmitting, from the UE, the concatenated unit of data from the UE to an evolved Node B (eNodeB).
