MFBMS Transceiver Frequency Band Allocation for Blocker Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless transceivers that support multiple frequency bands and standards face challenges in minimizing the adverse effects of blocker signals on received RF signals, particularly when signal strength differences are substantial, requiring multiple RF blocking circuits and duplexers to mitigate interference.
Innovation Solution
A network managing device with a transceiver and processing module allocates communication resources across multiple frequency band standards to establish separate communication paths, ensuring that transmission and reception frequencies are substantially separated, thereby minimizing the impact of blocker signals on received signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If multiple RF blocking circuits and duplexers are used to mitigate interference, then the blocker signal reduction is improved, but the device complexity increases
Solution Approach 1:
The patent changes the frequency parameter by allocating transmit and receive operations to different frequency bands. The transceiver uses a first frequency band for transmission and a second frequency band for reception, ensuring that the transmit frequency falls outside the receive frequency band. This frequency separation parameter change eliminates the need for multiple RF blocking circuits and duplexers, reducing device complexity while maintaining blocker signal reduction.
2Object-affected harmful factors
If transmit and receive frequencies are separated across different frequency bands, then blocker signal impact is reduced, but the communication resource allocation complexity increases
Solution Approach 1:
The patent implements dynamic frequency band allocation where the transceiver can switch between different frequency bands for transmit and receive operations based on communication needs. The processing module dynamically selects and allocates frequency resources, allowing flexible adaptation to different communication scenarios while maintaining the benefit of frequency separation for blocker reduction.

AI summary
A device includes a transcevier and a processing module. The transceiver is operable to receive a wireless communication request from a requesting wireless communication device and to convert the wireless communication request into a baseband or near baseband request signal. The processing module is operable to determine multiple frequency band multiple standard (MFBMS) capabilities of the requesting and the target wireless communication devices based on the baseband or near baseband request signal. When the devices have at least two frequency band standards in common, the processing module allocates a communication resource of one of the two frequency band standards for a first communication path from the requesting wireless communication device to the target wireless communication device and allocates a communication resource of another one of the two frequency band standards for a second communication path from the target wireless communication device to the requesting wireless communication device.
