Enhanced Channel State Information Measurement and Reporting at High Movement Speeds

A method, comprising:

• establishing, via a cellular network, a cellular link with a base station (BS);
• receiving, from the BS, radio resource control (RRC) signaling including channel state information (CSI) reporting configuration information;
• receiving, according to the CSI reporting configuration information, at least one burst of one or more CSI reference signals (CSI-RS) from the BS;
• and
• transmitting, to the BS, a first CSI report according to the CSI reporting configuration, wherein the first CSI report uses time-domain properties of the channel corresponding to the burst of the one or more CSI-RS.
• receiving, from the BS, modified CSI reporting configuration information;
• receiving, according to the modified CSI reporting configuration information, an adjusted burst of one or more additional CSI-RS from the BS;
• and
• transmitting, to the BS, an additional CSI report according to the modified CSI reporting configuration information.

An apparatus, comprising:

• a processor configured to, when executing instructions stored a memory, perform operations comprising:
• establishing, via a cellular network, a cellular link with a user equipment (UE);
• transmitting, to the UE, radio resource control (RRC) signaling including channel state information (CSI) reporting configuration information;
• transmitting, according to the CSI reporting configuration information, at least one burst of one or more CSI reference signals (CSI-RS) to the UE;
• receiving, from the UE, a first CSI report according to the CSI reporting configuration information, wherein the first CSI report uses time-domain properties of the channel corresponding to the burst of the one or more CSI-RS;
• determining, based on the first CSI report, modified CSI reporting configuration information;
• transmitting, to the UE, the modified CSI reporting configuration information;
• transmitting, according to the modified CSI reporting configuration information, an adjusted burst of one or more additional CSI-RS to the UE;
• and
• receiving, from the UE, an additional CSI report according to the modified CSI reporting configuration information.
