Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In joint communication and radar systems, especially in scenarios like the Internet of Vehicles, it is challenging to design a system where the communication module and detection module can operate effectively together without interference, as conventional designs often see radar detection signals deteriorating communication performance.
Innovation Solution
The system determines a sensing beam set where each sensing beam is selected from a beam codebook different from the communication beam, and transmits a combined beam that includes the communication beam and a sensing beam subset, allowing for simultaneous transmission and reception of multiple sensing beams to cover the entire detection angle range while minimizing interference with the communication beam.

1Device complexity
If radar detection signals are transmitted using the same hardware as communication module, then hardware resources are saved, but communication performance deteriorates due to interference
Solution Approach 1:
The patent segments the beam transmission by separating communication beams and sensing beams into different directional sets. The communication beam is transmitted in a first direction while sensing beams are transmitted in second directions that are different from the first direction, thereby spatially separating the two functions to reduce interference while sharing the same hardware resources.
Solution Approach 2:
The patent applies local quality by assigning different transmission characteristics to different spatial regions. The communication beam uses specific transmission parameters in its designated direction, while sensing beams use different parameters in other directions, allowing optimized performance for each function in its respective spatial zone.
2Productivity
If sensing beams are transmitted simultaneously with communication beam, then detection coverage is improved, but interference with communication signal increases
Solution Approach 1:
The patent segments the beam transmission by separating communication beams and sensing beams into different directional sets. The communication beam is transmitted in a first direction while sensing beams are transmitted in second directions that are different from the first direction, thereby spatially separating the two functions to reduce interference while sharing the same hardware resources.
Solution Approach 2:
The patent implements periodic action by controlling the transmission timing of sensing beams relative to the communication beam. The sensing beams are transmitted in a periodic manner with controlled duty cycles, allowing the communication beam to be transmitted in between sensing beam transmissions, thereby reducing mutual interference while maintaining detection coverage.
