Abstract
A user equipment (UE) includes a memory that stores a state of semi-persistent Channel State Information (CSI)-Reference Signal (RS) as a first state where the semi-persistent CSI-RS is activated or a second state where the semi-persistent CSI-RS is deactivated; a receiver that receives a predetermined trigger information; and a processor that changes the state in the memory and causes a transmitter to perform aperiodic CSI reporting based on the predetermined trigger information.
Claims14
A user equipment (UE) comprising:
- a memory that stores a state of semi-persistent Channel State Information (CSI)-Reference Signal (RS) as a first state where the semi-persistent CSI-RS is activated or a second state where the semi-persistent CSI-RS is deactivated;
- a receiver that receives a predetermined trigger information;
- and
- a processor that changes the state in the memory and causes a transmitter to perform aperiodic CSI reporting based on the predetermined trigger information.
A method of control of Channel State Information (CSI) reporting, the method comprising:
- managing, with a user equipment (UE), a state of semi-persistent CSI-Reference Signal (RS) as a first state where the semi-persistent CSI-RS is activated or a second state where the semi-persistent CSI-RS is deactivated;
- receiving, with the UE, a predetermined trigger information from a base station;
- changing, with the UE, the managed state based on the predetermined trigger information;
- and
- performing, with the UE, aperiodic CSI reporting based on the predetermined trigger information.
