Abstract

Methods, systems, and devices for wireless communications are described. The described techniques provide for a first device to perform data validation with one or more other devices. For example, a device may generate data at components associated with the device. To validate at least a portion of the data, the device may establish a connection with other devices. In some examples, the device may determine a portion of the data to validate based on a capability of the other devices to generate data that corresponds to the portion of data. The device may exchange data with the other devices and determine a validity of data generated at the device in response.

First claim

What is claimed is:

1. A method for wireless communications at a first device, comprising:
generating a first set of data associated with a plurality of components of the first device;
establishing, with one or more other devices, a wireless connection for validation of data generated at the plurality of components;
determining at least a subset of the first set of data for validation based at least in part on a capability of the one or more other devices to generate one or more other sets of data corresponding to the first set of data;
transmitting the subset of the first set of data to the one or more other devices;
receiving, from the one or more other devices, at least one other set of data corresponding to the subset of the first set of data;
determining at least one component of the plurality of components is experiencing a failure, wherein the first set of data is associated with the at least one component;
determining a second set of data associated with one or more other components of the plurality of components; and
determining a validity of the subset of the first set of data in response to receiving the at least one other set of data and the second set of data.

2. The method of claim 1 , further comprising:
determining the first set of data is invalid;
transmitting, to the one or more other devices, an indication that the first set of data is invalid; and
transmitting, to the one or more other devices, a request to initiate data sharing.

3. The method of claim 1 , further comprising:
determining the first set of data is valid; and
transmitting, to the one or more other devices, an indication that the first set of data is valid.

4. The method of claim 1 , further comprising:
dividing the plurality of components at the first device into one or more sets of components, wherein the first set of data is generated at a first set of components.

5. The method of claim 1 , wherein determining the validity of the first set of data comprises:
determining whether one or more parameters associated with the first set of data satisfy a threshold.

6. The method of claim 5 , wherein the one or more parameters comprise one or more of a latency parameter or a quality of service parameter.

7. The method of claim 1 , wherein establishing the wireless connection comprises:
establishing a vehicle-to-everything connection with the one or more other devices.

8. An apparatus for wireless communications at a first device, comprising:
one or more processors,
one or more memories coupled with the one or more processors; and
instructions stored in the one or more memories and executable by the one or more processors to cause the apparatus to:
generate a first set of data associated with a plurality of components of the first device;
establish, with one or more other devices, a wireless connection for validation of data generated at the plurality of components;
determine at least a subset of the first set of data for validation based at least in part on a capability of the one or more other devices to generate one or more other sets of data corresponding to the first set of data;
transmit the subset of the first set of data to the one or more other devices;
receive, from the one or more other devices, at least one other set of data corresponding to the subset of the first set of data;
determine at least one component of the plurality of components is experiencing a failure, wherein the first set of data is associated with the at least one component;
determine a second set of data associated with one or more other components of the plurality of components; and
determine a validity of the subset of the first set of data in response to receiving the at least one other set of data and the second set of data.

9. The apparatus of claim 8 , wherein the instructions are further executable by the one or more processors to cause the apparatus to:
determine the first set of data is invalid;
transmit, to the one or more other devices, an indication that the first set of data is invalid; and
transmit, to the one or more other devices, a request to initiate data sharing.

10. The apparatus of claim 8 , wherein the instructions are further executable by the one or more processors to cause the apparatus to:
determine the first set of data is valid; and
transmit, to the one or more other devices, an indication that the first set of data is valid.

11. The apparatus of claim 8 , wherein the instructions are further executable by the one or more processors to cause the apparatus to:
divide the plurality of components at the first device into one or more sets of components, wherein the first set of data is generated at a first set of components.

12. The apparatus of claim 8 , wherein the instructions to determine the validity of the first set of data are executable by the one or more processors to cause the apparatus to:
determine whether one or more parameters associated with the first set of data satisfy a threshold.

13. The apparatus of claim 12 , wherein the one or more parameters comprise one or more of a latency parameter or a quality of service parameter.

14. The apparatus of claim 8 , wherein the instructions to establish the wireless connection are executable by the one or more processors to cause the apparatus to:
establish a vehicle-to-everything connection with the one or more other devices.

15. An apparatus for wireless communications at a first device, comprising:
means for generating a first set of data associated with a plurality of components of the first device;
means for establishing, with one or more other devices, a wireless connection for validation of data generated at the plurality of components;
means for determining at least a subset of the first set of data for validation based at least in part on a capability of the one or more other devices to generate one or more other sets of data corresponding to the first set of data;
means for transmitting the subset of the first set of data to the one or more other devices;
means for receiving, from the one or more other devices, at least one other set of data corresponding to the subset of the first set of data;
means for determining at least one component of the plurality of components is experiencing a failure, wherein the first set of data is associated with the at least one component;
means for determining a second set of data associated with one or more other components of the plurality of components; and
means for determining a validity of the subset of the first set of data in response to receiving the at least one other set of data and the second set of data.

16. The apparatus of claim 15 , further comprising:
means for determining the first set of data is invalid;
means for transmitting, to the one or more other devices, an indication that the first set of data is invalid; and
means for transmitting, to the one or more other devices, a request to initiate data sharing.

17. The apparatus of claim 15 , further comprising:
