Abstract
A user equipment (UE), comprising: higher layer circuitry configured to receive information to configure a sidelink bandwidth part (BWP) and second information to configure one or more resource pool for sidelink transmission and/or reception; transmitting circuitry configured to transmit a physical sidelink control channel (PSCCH) and a physical sidelink shared channel (PSSCH), wherein subcarrier spacing is associated with the sidelink BWP, and a demodulation reference signal configuration for the PSCCH and PSSCH is configured for each of the one or more resource pools.
Claims4
A user equipment (UE), comprising:
- higher layer circuitry configured to receive first information to configure a sidelink bandwidth part (BWP) and second information to configure one or more resource pools for sidelink transmission and/or reception;
- and
- transmitting circuitry configured to transmit a physical sidelink control channel (PSCCH) and a physical sidelink shared channel (PSSCH), wherein
- the first information configures a subcarrier spacing,
- the second information configures, for each of the one or more resource pools, a demodulation reference signal configuration for the PSCCH and the PSSCH,
- the PSCCH is used for indicating sidelink control information (SCI),
- the SCI indicates resource allocation information of one or more resources for the PSSCH,
- the PSSCH is used for transmitting sidelink shared channel (SL-SCH), and
- the SL-SCH is V2X data.
A base station (BS), comprising:
- higher layer circuitry configured to transmit first information to configure a sidelink bandwidth part (BWP) and second information to configure one or more resource pools for sidelink communication, wherein
- the first information configures a subcarrier spacing,
- the second information configures, for each of the one or more resource pools, a demodulation reference signal configuration for a physical sidelink control channel (PSCCH) and a physical sidelink shared channel (PSSCH),
- the PSCCH is used for indicating sidelink control information (SCI),
- the SCI indicates resource allocation information of one or more resources for the PSSCH, the PSSCH is used for transmitting sidelink shared channel (SL-SCH), and the SL-SCH is V2X data.
