Title:

CSI-RS CONFIGURATION FOR PARTIAL BAND RETUNING

Document Type and Number:

WIPO Patent Application WO/2018/210098

Kind Code:

A1

Abstract:

Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive a message indicating, for each or multiple partial bands, a set of possible channel state information reference signal (CSI-RS) configurations. The UE may further receive downlink control information (DCI) from a base station, which may indicate a set of downlink resource associated with a first partial band. The UE may select a first CSI-RS configuration from the set of possible CSI-RS configurations for the first partial band based on the DCI, and when the base station transmits CSI-RS, the UE may obtain CSI-RS measurements over the first partial band during the set of downlink resources using the selected first CSI-RS configuration.
