Title: COUPLING APERIODIC CHANNEL STATE INFORMATION (CSI) REFERENCE SYMBOL (RS) (CSI-RS) STRUCTURE WITH FEEDBACK CONTENT AND REPORTING TIMING
Abstract:
Certain aspects of the present disclosure provide techniques for coupling a structure in which aperiodic channel state information reference symbols (CSI-RSs) are received with the content and timing of channel feedback. An example method generally includes receiving a request for channel feedback identifying a type of channel feedback to be provided to the BS and a type of CSI-RS to be used for generating the identified type of channel feedback, transmitting an indication of an amount of time used to generate the identified type of feedback based on the identified type of CSI-RS, receiving a triggering signal indicating at least a location of one or more CSI-RSs and a time at which the UE is to report the channel feedback, receiving the one or more CSI-RSs in the indicated location, generating the channel feedback based on the one or more CSI-RSs, and transmitting the generated feedback to the BS.
