Radio Module Paging Reception Without Data Interruption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face challenges in allowing one radio module to listen to paging signals without disrupting the data transmission of another radio module operating in connected mode, particularly when both modules share antennas and have different Radio Access Technologies (RATs).
Innovation Solution
The system employs at least two radio modules and antennas, with a processor arbitrating antenna usage based on DRX cycle durations and operational modes to ensure that one radio module can listen to paging signals without interrupting the other's data transmission, by yielding antenna access and reporting specific indicators to manage simultaneous activities.

Engineering Contradiction Analysis
1Adaptability or versatility
If one radio module listens to paging signals during connected mode, then standby functionality is improved, but data transmission of the other radio module may be interrupted
Solution Approach 1:
The patent segments the antenna resource by allowing different radio modules to use different antennas for different purposes. Specifically, when the first radio module needs to listen to paging signals, it can use one antenna while the second radio module uses another antenna for data transmission, thus avoiding interruption and resolving the conflict between standby functionality and data transmission reliability
Solution Approach 2:
The patent implements dynamic antenna switching and resource allocation based on the operational state of radio modules. The system dynamically adjusts which antenna is assigned to which radio module depending on whether they are in connected mode, idle mode, or performing receiving activities, thereby balancing standby functionality and data transmission reliability in real-time
2Device complexity
If multiple radio modules share antennas, then device complexity is reduced, but simultaneous receiving activities cannot be performed
Solution Approach 1:
The patent resolves the conflict by introducing a temporal dimension to antenna usage. When timing of receiving activities coincides, the system switches to using different antennas for different radio modules, effectively adding a spatial dimension (multiple antennas) to the temporal resource allocation problem, thereby enabling simultaneous receiving activities while maintaining simple shared antenna architecture
Solution Approach 2:
The system dynamically switches antenna assignments based on the timing of receiving activities. When the first radio module performs receiving activity at a different time than the second radio module, it can use a first antenna while the second radio module uses a second antenna, enabling simultaneous receiving activities without increasing overall device complexity
3Productivity
If antenna usage is arbitrated based on timing coincidence, then simultaneous receiving activities are enabled, but control complexity increases
Solution Approach 1:
The patent implements self-service mechanisms where each radio module autonomously determines its receiving activity timing and negotiates antenna usage with other modules. The arbitration logic is distributed across the radio modules themselves rather than centralized, reducing overall control complexity while still enabling simultaneous receiving activities through coordinated antenna assignment

AI summary
A communications apparatus. A first radio module communicates with a first wireless network and provides wireless communications services. A second radio module communicates with a second wireless network and provides wireless communications services. At least two antennas shared by the first radio module and the second radio module. When the first radio module operates in a connected mode and when the timing of the first radio module performing the first receiving activity coincides with the timing of the second radio module performing a second receiving activity, the first radio module reports a value of 1 for a Rank Indicator to the first wireless network at least once before the second radio module is to perform the second receiving activity, and then the second radio module uses one of the antennas to perform the second receiving activity.
