US 11,239,941 B2 · 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.

Dependent claims

A method for wireless communications at a first device in a wireless communications system, comprising:

determining a blind retransmission of a packet based at least in part on a previous transmission of the packet and exclusive of feedback by the first device in response to the previous transmission of the packet;
determining that the packet satisfies one or more conditions based at least in part on the blind retransmission;
and
transmitting a feedback signal relating to the blind retransmission of the packet based at least in part on determining that the packet satisfies the one or more conditions.

1 more element

A method for wireless communications at a first device in a wireless communications system, comprising:

receiving a feedback signal from a second device in the wireless communications system based at least in part on monitoring a feedback channel;
determining that the feedback signal satisfies one or more conditions;
and
excluding, from one or more candidate resources, one or more resources that overlap with one or more reserved resources corresponding to the feedback signal based at least in part on the determining.

1 more element

A method for wireless communications at a first device in a wireless communications system, comprising:

selecting one or more resources for transmission;
receiving a packet comprising a feedback signal from a second device in the wireless communications system based at least in part on monitoring a feedback channel;
determining that the feedback signal satisfies one or more conditions;
refraining from transmitting on the one or more resources that overlap with one or more reserved resources corresponding to the feedback signal based at least in part on the determining.
