ENHANCED RETRANSMISSION FOR SIDELINK COMMUNICATIONS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240243839 titled 'ENHANCED RETRANSMISSION FOR SIDELINK COMMUNICATIONS

The abstract describes a method for enhanced retransmission in sidelink communications, where a user equipment (UE) determines resources for initial transmission and blind retransmission of a transport block (TB) via a physical sidelink shared channel (PSSCH). If positive acknowledgment is not received after blind retransmissions, the UE switches to a hybrid automatic repeat request (HARQ)-based retransmission mode.

  • User equipment (UE) determines resources for initial transmission and blind retransmission of a transport block (TB) via a physical sidelink shared channel (PSSCH).
  • If positive acknowledgment is not received after blind retransmissions, the UE switches to a hybrid automatic repeat request (HARQ)-based retransmission mode.

Original Abstract Submitted

a method of enhanced retransmission in sidelink communications includes determining, by a user equipment (ue) based on a first number of blind retransmissions in a blind retransmission mode, a plurality of resources for an initial transmission and a blind retransmission of a first transport block (tb) via a physical sidelink shared channel (pssch); transmitting the first tb and the first number of blind retransmissions of the first tb; and in response to not receiving a positive acknowledgement after the first number of the blind retransmissions, switching from the blind retransmission mode to a hybrid automatic repeat request (harq)-based retransmission mode.
