Feedback techniques for wireless communications

Abstract:

Methods, systems, and devices for wireless communications are described. A device, which may be otherwise known as user equipment (UE) may support sidelink communications, for example, such as device-to-device (D2D) communications, vehicle-based communications, which may also be referred to as vehicle-to-everything (V2X) communications, vehicle-to-vehicle (V2V) communications, and the like. To mitigate or decrease collisions or other interference on resources (e.g., time and frequency resources) used by other UEs in sidelink communications, a UE may determine a blind retransmission of a packet, determine that the packet satisfies one or more conditions based in part on the blind retransmission, and transmit feedback signal relating to the blind retransmission of the packet.
