Abstract
Provided is a terminal apparatus configured to communicate with a base station apparatus. The terminal apparatus includes: a higher layer processing unit configured to receive first information including a setting for semi-persistent channel state information-reference signal (CSI-RS) for measuring channel state information; a medium access control (MAC) layer configured to receive second information including information for activating the semi-persistent CSI-RS; and a receiver configured to receive a physical downlink shared channel (PDSCH). In the terminal apparatus, in a case where the semi-persistent CSI-RS is activated, a resource element to be used for the activated reference signal is not to be used as a resource element for the physical downlink shared channel.

Claim
1. A terminal device comprising:
higher layer processing circuitry configured to:
receive a configuration of a resource for a channel state information-reference signal (CSI-RS),
receive a configuration indicating semi-persistent transmission of the CSI-RS,
receive a configuration of a channel state information-interference measurement (CSI-IM) resource, and
receive a first medium access control (MAC) control element (CE) and a second MAC CE,
wherein the first and second MAC CEs include information indicating whether to activate the CSI-RS and whether to activate the CSI-IM resource;
reception circuitry configured to:
receive a physical downlink shared channel (PDSCH),
receive the first MAC CE in a first slot, and
receive the second MAC CE in a second slot; and
measurement circuitry configured to:
measure channel state information (CSI) based on the CSI-RS,
wherein:
the CSI-RS is activated by the first MAC CE,
the PDSCH is not mapped on the resource for the CSI-RS, and
the CSI-IM resource is activated by the second MAC CE.
2. A base station device comprising:
higher layer processing circuitry configured to:
transmit a configuration of a resource for a channel state information-reference signal (CSI-RS),
transmit a configuration indicating semi-persistent transmission of the CSI-RS,
