Claim of US Patent No. 10,785,658

1. A user equipment used in a cellular wireless communication system, the user equipment comprising:a wireless communication module; and
a processor,
wherein the processor is configured to:
receive Channel State Information Reference Signal (CSI-RS) configuration information indicating one of plurality of CSI-RS configuration information included in a CSI-RS configuration information set for a downlink cell from a base station, and
receive CSI-RS in the downlink cell according to the CSI-RS configuration information from the base station,
wherein when the downlink cell operates in a licensed band, the CSI-RS configuration information set is a first CSI-RS configuration information set including one or more first CSI-RS configuration information related to Orthogonal Frequency Division Multiplexing (OFDM) symbols #5/#6, one or more second CSI-RS configuration information related to OFDM symbols #9/#10, and one or more third CSI-RS configuration information related to OFDM symbols #12/#13,
wherein when the downlink cell operates in an unlicensed band, the CSI-RS configuration information set is a second CSI-RS configuration information set,
wherein the second CSI-RS configuration information set is part of the first CSI-RS configuration set and does not comprise the one or more third CSI-RS configuration information.
