Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Single radio transceiver devices face challenges in efficiently allocating resources for paging signal reception from one network while communicating in another network, leading to potential throughput losses, especially during ongoing UMTS LTE data calls.
Innovation Solution
A method that dynamically allocates time periods for receiving paging signals from a secondary radio access technology, adjusting based on previous decoding success, to minimize interference with primary network communication, using a radio scheduler and decoder to optimize the number of bursts required for successful decoding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single radio transceiver is used to monitor paging from legacy network while connected to UMTS LTE, then parallel paging reception is enabled, but throughput loss occurs in UMTS LTE data transfer
Solution Approach 1:
The patent implements dynamic allocation of time periods for paging reception, where the number of time periods is adjusted based on decoding results from previous paging signals. This dynamic adaptation allows the system to optimize the balance between paging monitoring and data transfer, reducing throughput loss while maintaining parallel paging reception capability.
Solution Approach 2:
The system uses feedback from decoding results of previous paging signals to determine the number of time periods to allocate for subsequent paging reception. This feedback mechanism enables the transceiver to adapt its behavior based on actual channel conditions and decoding success, thereby minimizing the impact on UMTS LTE throughput while ensuring reliable paging reception.
2Reliability
If more time periods are allocated to paging reception, then paging signal decoding reliability improves, but UMTS LTE data transfer performance deteriorates
Solution Approach 1:
The patent dynamically adjusts the number of time periods allocated to paging reception based on real-time decoding results. When decoding is successful with fewer time periods, the system reduces allocation to preserve UMTS LTE throughput. When decoding reliability is insufficient, the system increases allocation, creating a dynamic balance between reliability and productivity.
Solution Approach 2:
The system changes the parameter of time period allocation based on decoding performance. By monitoring decoding success rates and adjusting the number of time periods accordingly, the system optimizes the trade-off between paging reception reliability and data transfer performance, avoiding fixed allocation that would always sacrifice one for the other.
3Device complexity
If the number of time periods for paging reception is fixed, then system complexity is reduced, but adaptability to varying channel conditions decreases
Solution Approach 1:
The system implements self-service through autonomous adjustment of time period allocation based on decoding results. The transceiver automatically determines the appropriate number of time periods without external intervention, adapting to channel conditions while maintaining relatively simple control logic. This self-adjusting mechanism provides adaptability without significantly increasing system complexity.

AI summary
A method is disclosed of a wireless communication device adapted to communicate using a radio access transceiver alternatingly in accordance with a first radio access technology and in accordance with a second radio access technology. The method comprises allocating a number of time periods during communication in accordance with the first radio access technology to reception of a paging signal of the second radio access technology, wherein the number is dynamically variable based on a result of a (block) decoding of at least one previous paging signal of the second radio access technology. The number may be set based on at least one respective previous number of time periods required for successful (block) decoding of the at least one previous paging signal. Furthermore, the number may be set to a maximum value if an immediately previous paging signal was not successfully decoded.
