Abstract
Official abstract text for this publication.
Channel state information (CSI) request procedures are disclosed for use in wireless communication systems. The serving base station transmits an identifier, which signals that the aperiodic reference signal will be transmitted, either in the same subframe or a future subframe, and then transmits the aperiodic reference signal in the designated subframe. UEs served by the base station will receive the identifier, identify a CSI request, either implicitly through the identifier signal received from the base station or explicitly through a UE-specific CSI request, and then generate a CSI report based on the aperiodic reference signal for transmission back to the serving base station.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method of wireless communication, comprising: detecting, by a user equipment (UE), an identifier signaling presence of an aperiodic reference signal in a subframe, wherein the identifier indicates a selected aperiodic reference signal configuration; identifying, by the UE, a channel state information, CSI, request from a base station; generating, by the UE, a CSI report based on the aperiodic reference signal in response to the CSI request; and transmitting, by the UE, the CSI report to the base station.
