Abstract

A user equipment (UE) that performs sidelink (SL) communications is described. The UE includes receiving circuitry configured to: receive a first radio resource control (RRC) message comprising first information used for configuring an SL bandwidth part (SL BWP). The receiving circuitry is also configured to receive a second RRC message comprising second information used for configuring one or more resource pools for SL transmission within the SL BWP. The receiving circuitry is further configured to receive a third RRC message comprising third information used for configuring a sidelink channel state information-reference signal (SCSI-RS). The UE also includes transmitting circuitry configured to perform SL channel state information (CSI) reporting based on the third information. The third information is associated with at least one of the SL BWP and one resource pool of the one or more resource pools for the SL transmission.

First claim

The invention claimed is:

1. A user equipment (UE) that performs sidelink (SL) communications, the UE comprising:
receiving circuitry configured to:
receive a first radio resource control (RRC) message comprising first information used for configuring an SL bandwidth part (BWP);
receive a second RRC message comprising second information used for configuring one or more resource pools for SL transmission within the SL BWP; and
receive a third RRC message comprising third information used for configuring a sidelink channel state information (SCSI)-reference signal (RS); and

transmitting circuitry configured to perform SL channel state information (CSI) reporting based on the third information, wherein
the third information is associated with at least one of the SL BWP and one resource pool of the one or more resource pools for the SL transmission.

2. A base station apparatus, comprising:
transmitting circuitry configured to:
transmit a first radio resource control (RRC) message comprising first information used for configuring a sidelink (SL) bandwidth part (BWP);
transmit a second RRC message comprising second information used for configuring one or more resource pools for SL transmission within the SL BWP; and
transmit a third RRC message comprising third information used for configuring a sidelink channel state information (SCSI)-reference signal (RS), wherein;

SL channel state information (CSI) reporting is performed based on the third information, and
the third information is associated with at least one of the SL BWP and one resource pool of the one or more resource pools for the SL transmission.

3. A communication method performed by a user equipment for performing sidelink (SL) communications, the communication method comprising:
receiving a first radio resource control (RRC) message comprising first information used for configuring an SL bandwidth part (BWP);
receiving a second RRC message comprising second information used for configuring one or more resource pools for SL transmission within the SL BWP;
receiving a third RRC message comprising third information used for configuring a sidelink channel state information (SCSI)-reference signal (RS); and
performing SL channel state information (CSI) reporting based on the third information, wherein
the third information is associated with at least one of the SL BWP and one resource pool of the one or more resource pools for the SL transmission.

4. A communication method performed by a base station apparatus, the communication method comprising:
transmitting a first radio resource control (RRC) message comprising first information used for configuring a sidelink (SL) bandwidth part (BWP);
transmitting a second RRC message comprising second information used for configuring one or more resource pools for SL transmission within the SL BWP; and
transmitting a third RRC message comprising third information used for configuring a sidelink channel state information (SCSI)-reference signal (RS), wherein:
SL channel state information (CSI) reporting is performed based on the third information, and
the third information is associated with at least one of the SL BWP and one resource pool of the one or more resource pools for the SL transmission.
