Abstract
A system, method and apparatus for wireless communications is provided. A user equipment (UE) receives one or more messages. The one or more messages include first configuration parameters for channel state information, reference signal (CSI-RS) measurement and CSI report in a first radio resource control (RRC) state. The one or more messages also include second configuration parameters for the CSI-RS measurement and the CSI report in a second RRC state. The UE transmits a first CSI report, based on the first configuration parameters, when the UE is in the first RRC state. The UE transmits a second CSI report, based on the second configuration parameters, when the UE is in the second RRC state.

A method of channel state information (CSI) feedback comprising:
- receiving, by a user equipment (UE), one or more messages comprising:
- first configuration parameters for channel state information-reference signal (CSI-RS) measurement and CSI report in a first radio resource control (RRC) state;
- and
- second configuration parameters for the CSI-RS measurement and the CSI report in a second RRC state;
- transmitting a first CSI report, based on the first configuration parameters, when the UE is in the first RRC state;
- and
- transmitting a second CSI report, based on the second configuration parameters, when the UE is in the second RRC state.
A method of channel state information (CSI) feedback for multicast broadcast services (MBS) comprising:
- receiving, by a user equipment (UE), configuration parameters for a channel state information-reference signal (CSI-RS) measurement and a CSI report associated with multicast broadcast services (MBSs);
- determining, based on the received configuration parameters, a CSI report associated with the MBSs for transmission at a first timing;
- and
- dropping the CSI report where the first timing of the CSI report collides with a second timing associated with at least one of an uplink channel or an uplink signal.
A method of channel state information (CSI) feedback comprising:
- transmitting, by a base station, one or more messages comprising:
- first configuration parameters for channel state information-reference signal (CSI-RS) measurement and CSI report in a first radio resource control (RRC) state;
- and
- second configuration parameters for the CSI-RS measurement and the CSI report in a second RRC state;
- receiving a first CSI report, based on the first configuration parameters, when the UE is in the first RRC state;
- and
- receiving a second CSI report, based on the second configuration parameters, when the UE is in the second RRC state.
