Abstract
A method for transmitting data over a SL data channel wherein a transmit UE and a receive UE are each semi-statically provided with a CG configuration such that a CG configuration indication does not have to be transmitted in association with each individual data transmission during a duration that the CG configuration is applied.
Claims25
A method, comprising:
- transmitting, by a transmitting (Tx) user equipment (UE) for a receiving (Rx) user equipment (UE), a first sidelink (SL) signal indicating configured grant (CG) configuration parameters, the CG configuration parameters for allocating a set of transmission resources;
- and
- transmitting, by the Tx UE, multiple SL data transmissions for the Rx UE in a SL data channel according to the CG configuration parameters on the set of transmission resources, wherein at least one of the multiple SL data transmissions is transmitted without being scheduled by a respective transmission in a physical SL control channel (PSCCH) indicating the CG configuration parameters, the Tx UE semi-statically applying the CG configuration parameters with effect that the CG configuration parameters do not have to be transmitted in association with each individual SL data transmission from the Tx UE to the Rx UE during a duration that the CG configuration is applied.
An apparatus comprising at least one processor coupled with a non-transitory computer-readable medium storing instructions, wherein when the instructions executed by the at least one processor, cause the apparatus to:
- transmit, by a transmitting (Tx) user equipment (UE) for a receiving (Rx) user equipment (UE), a first sidelink (SL) signal indicating configured grant (CG) configuration parameters, the CG configuration parameters for allocating a set of transmission resources;
- and
- transmit, by the Tx UE, multiple SL data transmissions for the Rx UE in a SL data channel according to the CG configuration parameters on the set of transmission resources, wherein at least one of the multiple SL data transmissions is transmitted without being scheduled by a respective transmission in a physical SL control channel (PSCCH) indicating the CG configuration parameters, the Tx UE semi-statically applying the CG configuration parameters with effect that the CG configuration parameters do not have to be transmitted in association with each individual SL data transmission from the Tx UE to the Rx UE during a duration that the CG configuration is applied.
A computer program product comprising a non-transitory computer readable medium storing instructions for configuring a transmitting (Tx) user equipment to:
- transmit, for a receiving (Rx) UE, a first SL signal indicating configured grant (CG) configuration parameters, the CG configuration parameters for allocating a set of transmission resources;
- and
- transmit multiple SL data transmissions in a SL data channel for the Rx UE according to the indicated CG configuration parameters on the set of transmission resources, wherein at least one of the multiple SL data transmissions is transmitted without being scheduled by a respective transmission in a physical SL control channel (PSCCH) indicating the CG configuration parameters, the Tx UE semi-statically applying the CG configuration parameters with effect that the CG configuration parameters do not have to be transmitted in association with each individual SL data transmission from the Tx UE to the Rx UE during a duration that the CG configuration is applied.
A method, comprising:
- receiving, from a transmitting (Tx) user equipment (UE), a first sidelink (SL) signal indicating configured grant (CG) configuration parameters, the CG configuration parameters for allocating a set of transmission resources;
- and
- receiving multiple SL data transmissions from the Tx UE in a SL data channel according to the CG configuration parameters on the set of transmission resources, wherein at least one of the multiple SL data transmissions is received without being scheduled by a respective transmission from the Tx UE in a physical SL control channel (PSCCH) indicating the CG configuration parameters, the Tx UE semi-statically applying the CG configuration parameters with effect that the CG configuration parameters do not have to be transmitted in association with each individual SL data transmission from the Tx UE to the Rx UE during a duration that the CG configuration is applied.
An apparatus, comprising at least one processor coupled with a non-transitory computer-readable medium storing instructions, wherein when the instructions executed by the at least one processor, cause the apparatus to:
- receive, from a transmitting (Tx) user equipment (UE), a first sidelink (SL) signal indicating configured grant (CG) configuration parameters, the CG configuration parameters for allocating a set of transmission resources;
- and
- receive multiple SL data transmissions from the Tx UE in a SL data channel according to the CG configuration parameters on the set of transmission resources, wherein at least one of the multiple SL data transmissions is received without being scheduled by a respective transmission from the Tx UE in a physical SL control channel (PSCCH) indicating the CG configuration parameters, the Tx UE semi-statically applying the CG configuration parameters with effect that the CG configuration parameters do not have to be transmitted in association with each individual SL data transmission from the Tx UE to the Rx UE during a duration that the CG configuration is applied.
