Frequency Hopping Puncture Pattern for Collocated Transceiver Coexistence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional techniques for coexistence of collocated transceivers in wireless devices are limited, leading to inefficient bandwidth usage and increased latency due to overlapping frequency ranges and time slots.
Innovation Solution
Implementing a puncturing scheme that allows a first transceiver to identify and enable the use of unused sub-channels by a second collocated transceiver, thereby partitioning and sharing bandwidth more efficiently.

Engineering Contradiction Analysis
1Device complexity
If conventional coexistence techniques are used for collocated transceivers, then device complexity is reduced, but bandwidth utilization deteriorates
Solution Approach 1:
The available bandwidth is segmented into multiple sub-channels, allowing the first transceiver to selectively puncture (exclude) only the sub-channels it needs while making other sub-channels available to the second transceiver. This segmentation enables fine-grained bandwidth sharing without requiring complex coordination protocols.
Solution Approach 2:
The puncturing pattern is dynamically adjusted based on the first transceiver's current bandwidth needs. When the first transceiver requires more bandwidth, it punctures fewer sub-channels; when it needs less, it punctures more sub-channels to make them available to the second transceiver. This dynamic adaptation optimizes bandwidth utilization without increasing device complexity.
2Ease of operation
If conventional coexistence techniques are used for collocated transceivers, then ease of operation is maintained, but latency increases
Solution Approach 1:
The first transceiver pre-determines its puncturing pattern based on anticipated bandwidth needs and communicates this pattern to the second transceiver in advance. This preliminary action allows the second transceiver to proactively use the punctured sub-channels without waiting for dynamic negotiation, thereby reducing latency while maintaining operational simplicity.
3Device complexity
If bandwidth is shared between collocated transceivers using conventional techniques, then device complexity is minimized, but bandwidth utilization deteriorates
Solution Approach 1:
The bandwidth is divided into multiple sub-channels that can be independently punctured and shared. This segmentation allows the first transceiver to precisely control which sub-channels are available to the second transceiver, maximizing bandwidth utilization without requiring complex sharing mechanisms.
Solution Approach 2:
The system changes the operational parameters of the transceivers by introducing puncturing patterns that dynamically adjust the effective bandwidth allocation. By modifying parameters such as the puncturing pattern and sub-channel assignment, the system achieves efficient bandwidth utilization while keeping the sharing mechanism relatively simple.

AI summary
Systems, methods, and devices provide improved coexistence of collocated transceivers. Methods include identifying, using one or more processing elements, wireless activity associated with a first transceiver, the first transceiver being collocated with a second transceiver, and generating, using the one or more processing elements, a puncture pattern for the first transceiver based, at least in part, on the identified wireless activity, the puncture pattern identifying an unused plurality of sub-channels of the first transceiver. Methods also include generating, using the one or more processing elements, a hopping pattern for the second transceiver based, at least in part, on the puncture pattern, the hopping pattern identifying a sequence of sub-channels used by the second transceiver for wireless activity, and the hopping pattern including at least some of the plurality of sub-channels identified by the puncture pattern.
