Sidelink resource allocation and communication

A user equipment (UE), comprising:

• at least one processor;
• and
• at least one memory communicatively coupled with the at least one processor and storing processor-readable code that, when executed by the at least one processor in conjunction with at least one modem, is configured to:
• receive, from a base station, a single message that indicates a first transmission opportunity for transmission of information from the UE to a second UE and that indicates one or more additional transmission opportunities for at least one subsequent transmission of information from the UE to the second UE;
• initiate transmission of the information to the second UE in the first transmission opportunity;
• and
• retransmit the information to the second UE in at least one of the one or more additional transmission opportunities responsive to the transmission of the information in the first transmission opportunity being unsuccessful.

A base station, comprising:

• at least one processor;
• and
• at least one memory communicatively coupled with the at least one processor and storing processor-readable code that, when executed by the at least one processor in conjunction with at least one modem, is configured to:
• transmit, to a user equipment (UE), a single message that indicates a first transmission opportunity for transmission of information from the UE to a second UE and that indicates one or more additional transmission opportunities for at least one subsequent transmission of information from the UE to the second UE;
• and
• after transmission of the information to the second UE in the first transmission opportunity, receive, from the UE, an indication as to whether retransmission of the information in the one or more additional transmission opportunities from the UE to the second UE was successful.
