UAV Broadcast Message Type Signaling for Selective Decoding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face inefficiencies in identifying the intended recipient of messages transmitted by unmanned aerial vehicles (UAVs), leading to excessive power consumption and resource utilization as receiving devices decode messages not intended for them.
Innovation Solution
UAVs transmit control information indicating the message type, such as UAV-to-UAV or UAV-to-terrestrial UE messages, allowing receiving devices to determine whether to decode the message based on the indicated type.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If receiving devices decode all messages without early indication of message type, then all messages can be received, but power consumption and resource utilization increase excessively
Solution Approach 1:
The patent applies preliminary action by transmitting control information before the actual message to indicate the message type. This allows receiving devices to prepare in advance by determining whether they need to decode the upcoming message based on the indicated type, thereby avoiding unnecessary decoding operations and reducing power consumption while ensuring reliable message reception when needed
2Reliability
If receiving devices decode all messages without early indication of message type, then no messages are missed, but resource utilization increases excessively
Solution Approach 1:
The control information is transmitted in advance to indicate message type, enabling receiving devices to make preliminary decisions about whether to allocate decoding resources. This preliminary action prevents wasted resource utilization on irrelevant messages while maintaining reliable reception of intended messages through timely resource allocation
3Use of energy by moving object
If control information is transmitted to indicate message type, then power consumption and resource utilization are reduced, but device complexity increases
Solution Approach 1:
The communication protocol is segmented into two distinct parts: control information that indicates message type, and the actual message content. This segmentation allows receiving devices to process only the relevant portion based on the control indication, reducing overall power consumption and resource utilization despite the added structural complexity of the protocol

AI summary
Methods, systems, and devices for wireless communication are described. An aerial vehicle (a transmitting device) may transmit control information that indicates a message type of a message. The message type may be one of multiple aerial vehicle broadcast message types, such as an aerial vehicle-to-aerial vehicle message type or an aerial vehicle-to-terrestrial user equipment (UE) message type. The transmitting device may transmit the message to a receiving device (e.g., another aerial vehicle or a terrestrial UE) in accordance with the indicated message type. For example, the transmitting device may transmit an aerial vehicle-to-aerial vehicle message to another nearby aerial vehicle or an aerial vehicle-to-terrestrial UE message to a terrestrial UE. As such, a receiving device may be aware of a message type and determine whether to decode the message accordingly.
