Reference signal notification method and apparatus

A reference signal notification method, performed by a user equipment (UE) or a chipset for the UE, the method comprising:

• sending information about one or more synchronization signal (SS) blocks, wherein the information about the one or more SS blocks comprises at least one time index of the one or more SS blocks;
• receiving a reference signal notification message, wherein the reference signal notification message comprises time resource information of a channel state information reference signal (CSI-RS), period information of the CSI-RS, and a cell identity and numerology information of the CSI-RS, wherein the time resource information is a time offset of the CSI-RS, wherein the period information indicates a periodicity of the CSI-RS, wherein the numerology information of the CSI-RS indicates a subcarrier spacing of the CSI-RS, wherein the reference signal notification message further comprises reference information used to indicate whether the time resource information is based on a current cell or a neighboring cell, and wherein the reference signal notification message further comprises beam information related to at least one time index of one or more synchronization signal (SS) blocks;
• and
• receiving the CSI-RS based on the time resource information of the CSI-RS.

A reference signal notification apparatus, comprising a transceiver, wherein

• the transceiver is configured to:
• receive information about one or more synchronization signal (SS) blocks, wherein the information about the one or more SS blocks comprises at least one time index of the one or more SS blocks;
• and
• send a reference signal notification message, wherein the reference signal notification message comprises time resource information of a channel state information reference signal (CSI-RS), period information of the CSI-RS, and a cell identity and numerology information of the CSI-RS wherein the time resource information is a time offset of the CSI-RS, wherein the period information indicates a periodicity of the CSI-RS, wherein the numerology information of the CSI-RS indicates a subcarrier spacing of the CSI-RS, wherein the reference signal notification message further comprises reference information used to indicate whether the time resource information is based on a current cell or a neighboring cell, and wherein the reference signal notification message further comprises beam information related to at least one time index of one or more synchronization signal (SS) blocks.
