Patent ID: 11546937

Abstract:
Methods and systems are provided that facilitate sidelink (SL) retransmission scheduled by the network if a SL transmission of a transport block (TB) is unsuccessful. Signalling is used by the network to send a configured grant of transmission resources available for SL transmissions by the UE that repeat on a periodic basis within each of period. The UE makes SL transmissions during one of the periods by transmitting one or more SL transmissions of at least one transport block using the configured resources. The network can schedule a retransmission by transmitting a downlink control information (DCI) to schedule a SL retransmission of one of the transmitted TB. The UE transmits a SL transmission containing a retransmission of the transport block using resources specified in the DCI. The UE transmits a sidelink control information associated with each SL transmission, containing a HARQ process ID for the SL transmission.
