Channel state information procedure for enhanced component carriers

An apparatus for wireless communication, comprising:

• means for receiving one or more downlink reference signals in a variable length downlink transmission time interval (TTI), wherein the variable length downlink TTI comprises a variable number of downlink symbols;
• means for estimating channel state information (CSI) for one or more of the downlink reference signals;
• and
• means for identifying at least a portion of the estimated CSI for transmission in a CSI report in a variable length uplink TTI.

An apparatus for wireless communication, comprising:

• a processor;
• memory in electronic communication with the processor;
• and
• instructions stored in the memory, the instructions being executable by the processor to cause the apparatus to:
• receive one or more downlink reference signals in a variable length downlink transmission time interval (TTI), wherein the variable length downlink TTI comprises a variable number of downlink symbols;
• estimate channel state information (CSI) for one or more of the downlink reference signals;
• and
• identify at least a portion of the estimated CSI for transmission in a CSI report in a variable length uplink TTI.

A non-transitory computer-readable medium storing computer-executable code for wireless communication, the code executable to:

• receive one or more downlink reference signals in a variable length downlink transmission time interval (TTI), wherein the variable length downlink TTI comprises a variable number of downlink symbols;
• estimate channel state information (CSI) for one or more of the downlink reference signals;
• and
• identify at least a portion of the estimated CSI for transmission in a CSI report in a variable length uplink TTI.
