Abstract
A user equipment (UE) indicates an intent to transmit on sidelink sub-channels using a transmission indication and then monitors receptions of transmission grants transmitted from one or more other devices, such as UEs or base stations, and determines whether or not to proceed with the sidelink transmission on the sub-channels based on the received transmission grants. A device monitors transmission indications transmitted from UEs to determine a UE that can proceed with a sidelink transmission on sub-channels, and transmits a transmission grant corresponding to the UE that can proceed with the sidelink transmission on sub-channels.
Claims20
A user equipment (UE), comprising:
- a controller configured to select sidelink (SL) resources within a set of SL resources;
- and
- a transceiver, coupled to the controller, configured to:
- transmit an indication of the selected SL resources, and
- receive, in response to transmission of the indication, a grant for transmission on the selected SL resources,
- wherein:
- the controller is further configured to determine whether or not to provide an instruction to the transceiver to transmit in the selected SL resources based on the grant, and
- the transceiver is further configured to transmit in the selected SL resources based on the instruction.
A method, comprising:
- selecting sidelink (SL) resources within a set of SL resources;
- transmitting an indication of the selected SL resources;
- receiving, in response to transmission of the indication, a grant for transmission on the selected SL resources;
- determining whether or not to transmit in the selected SL resources based on the grant;
- and
- transmitting in the selected SL resources based on the determination.
A device, comprising:
- a transceiver configured to receive indications of selected sidelink (SL) resources for SL transmission by first user equipments (UEs);
- and
- a controller configured to determine priority values for corresponding second UEs relative to the first UEs, wherein:
- the second UEs have overlapping selected SL resources, and
- the transceiver is further configured to transmit a grant providing a priority value to a UE from the second UEs.
