Method and device of transmitting and receiving channel state information report

A method of transmitting a channel state information (CSI) report, applied to a user equipment (UE), comprising:

• receiving a first indication on a second downlink (DL) frequency domain transmission resource, wherein the first indication is used to activate a first DL frequency domain transmission resource;
• transmitting a CSI report on a first uplink (UL) frequency domain transmission resource according to a first CSI report configuration corresponding to the first DL frequency domain transmission resource when it is determined that there is the first CSI report configuration and it is determined that a CSI-reference signal (RS) corresponding to the first CSI report configuration is received on the first DL frequency domain transmission resource, wherein the first CSI report configuration comprises a periodicity characteristic of the CSI report;
• and
• stopping transmitting a semi-persistent (SP) CSI report corresponding to the second DL frequency domain transmission resource when the SP CSI report is activated for the second DL frequency domain transmission resource and the second DL frequency domain transmission resource is switched to the first DL frequency domain transmission resource.
