Engineering Contradiction Analysis
1Productivity
If Multiple Users Reusing One Single time slot (MUROS) concept is applied to enhance cell capacity, then the number of users that can communicate simultaneously increases, but communication quality degrades due to Co-Channel Interference and power imbalance
Solution Approach 1:
The base station performs preliminary actions by selecting and pairing communication devices before assigning them to the same time slot. It evaluates Timing Advance values and device types in advance to ensure compatible pairs are formed, preventing co-channel interference and power imbalance issues from arising during communication.
Solution Approach 2:
The invention changes the parameter of device pairing criteria by considering both Timing Advance values and device types when selecting communication devices for the same time slot. This multi-parameter approach ensures that paired devices have compatible characteristics, maintaining communication quality while enabling MUROS functionality.
2Productivity
If communication devices are paired in a single time slot to increase user capacity, then more users can communicate simultaneously, but sudden degradation in link quality occurs due to Co-Channel Interference
Solution Approach 1:
The base station acts as an intermediary that mediates between multiple communication devices before pairing them in the same time slot. It evaluates Timing Advance values and device types as intermediate criteria to select compatible pairs, thereby reducing co-channel interference while enabling multiple simultaneous users.
3Productivity
If communication devices are paired in a single time slot to increase user capacity, then more users can communicate simultaneously, but power imbalance ratio between users causes communication quality degradation
Solution Approach 1:
The base station performs preliminary evaluation of Timing Advance values and device types before pairing communication devices. This preliminary action ensures that paired devices have compatible power characteristics, preventing power imbalance issues while enabling multiple users to share the same time slot.
4Reliability
If a proper criterion for user pairing or allocation mechanism is implemented to mitigate Co-Channel Interference, then communication quality improves, but device complexity increases due to additional selection and pairing processes
Solution Approach 1:
The invention simplifies the pairing mechanism by changing the selection parameters to Timing Advance values and device types. These are already available parameters in the system, so using them for pairing avoids adding complex new evaluation criteria while still effectively reducing co-channel interference.
