Channel state information reporting for systems with multiple transmission time intervals

An apparatus for wireless communication, comprising:

• means for establishing a configuration for communication via a first transmission time interval (TTI) length and a second TTI length that is shorter than the first TTI length;
• means for identifying a trigger for a channel state information (CSI) report associated with the second TTI length, wherein the CSI report is associated with a reporting TTI having the first TTI length;
• means for identifying a first TTI of the first TTI length based at least in part on the reporting TTI for the CSI report;
• means for identifying a reference resource for the CSI report, wherein the reference resource comprises a TTI having the second TTI length within the first TTI and is identified based at least in part on a reporting configuration associated with the second TTI length;
• means for generating the CSI report based at least in part on the reference resource;
• and
• means for transmitting the CSI report during the reporting TTI and in response to the identified trigger.

An apparatus for wireless communication, comprising:

• a processor;
• memory in electronic communication with the processor;
• and
• instructions stored in the memory and operable, when executed by the processor, to cause the apparatus to:
• establish a configuration for communication utilizing a first transmission time interval (TTI) length and a second TTI length that is shorter than the first TTI length;
• identify a trigger for a channel state information (CSI) report associated with the second TTI length, wherein the CSI report is associated with a reporting TTI having the first TTI length;
• identify a first TTI of the first TTI length based at least in part on the reporting TTI for the CSI report;
• identify a reference resource for the second TTI length for the CSI report, wherein the reference resource comprises a TTI having the second TTI length within the first TTI and is identified based at least in part on a reporting configuration associated with the second TTI length;
• generate the CSI report based at least in part on the reference resource;
• and
• transmit the CSI report during the reporting TTI and in response to the identified trigger.

A non-transitory computer-readable medium storing code for wireless communication, the code comprising instructions executable by a processor to:

• establish a configuration for communication utilizing a first transmission time interval (TTI) length and a second TTI length that is shorter than the first TTI length;
• identify a trigger for a channel state information (CSI) report associated with the second TTI length, wherein the CSI report is associated with a reporting TTI having the first TTI length;
• identify a first TTI of the first TTI length based at least in part on the reporting TTI for the CSI report;
• identify a reference resource for the CSI report, wherein the reference resource comprises a TTI having the second TTI length within the first TTI and is identified based at least in part on a reporting configuration associated with the second TTI length;
• generate the CSI report based at least in part on the reference resource;
• and
• transmit the CSI report during the reporting TTI and in response to the identified trigger.
