Repeater Frequency Selection via Network Criteria
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for selecting relay frequencies in repeaters lack dynamic behavior, failing to adapt to changing network conditions, especially in multi-carrier LTE systems, leading to suboptimal performance.
Innovation Solution
A system and method where a repeater dynamically selects channels to relay by examining network criteria broadcast by the network, combined with signal strength measurements, using Cell Selection and Cell Reselection criteria, to prioritize and reconfigure frequency bands based on network conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed configuration is loaded into the repeater to relay specific frequency bands, then the repeater can operate with a simple configuration, but the configuration becomes static and cannot adapt to changing network conditions
Solution Approach 1:
The repeater dynamically selects frequency bands to relay by monitoring network conditions and comparing them against stored configuration options. The system transitions from a static fixed configuration to a dynamic selection process where the repeater can change which frequency bands it relays based on current network state, resolving the contradiction between adaptability and complexity.
Solution Approach 2:
The repeater autonomously determines which frequency bands to relay by evaluating network conditions against stored configurations without requiring external control. The system serves itself by making independent decisions about frequency band selection, eliminating the need for complex external management while maintaining adaptability.
2Adaptability or versatility
If multiple configuration options are available for the repeater, then the repeater can potentially adapt to different network conditions, but it becomes difficult to select an appropriate configuration
Solution Approach 1:
The repeater continuously monitors network conditions and uses this feedback to automatically select the most appropriate configuration from available options. By implementing a feedback loop that compares current network state against stored configurations, the system eliminates the difficulty of manual configuration selection while preserving the benefits of multiple configuration options.
Solution Approach 2:
The repeater autonomously evaluates multiple configuration options against current network conditions and independently selects the most appropriate configuration. This self-service approach removes the burden of configuration selection from operators while maintaining the flexibility of having multiple configuration options available.
3Productivity
If the repeater uses a simple fixed configuration approach, then the device complexity is low, but the repeater performance is suboptimal in multi-carrier LTE systems with changing network conditions
Solution Approach 1:
The repeater implements a dynamic frequency band selection mechanism that monitors network conditions and adjusts which frequency bands to relay in real-time. This dynamic approach significantly improves signal relay efficiency in multi-carrier LTE systems compared to static configurations, while the complexity added is managed through automated decision-making algorithms.
Solution Approach 2:
The repeater changes operational parameters (specifically which frequency bands are relayed) based on monitored network conditions. By dynamically adjusting these parameters rather than maintaining a fixed configuration, the system achieves optimal performance in varying network environments while managing complexity through parameter-based adaptation.

AI summary
A system includes a repeater and a data processor. The repeater is for relaying data between a base station and a handset. The repeater is configured to receive data from a plurality of cells in a network and relay at least a portion of the received data to a handset on a first channel. The data processor is coupled to the repeater. The data processor is configured to extract, from the received data, network criteria characterizing a priority of different channels in the network. The data processor is configured to determine, based on the extracted network criteria, a second channel based on the priority of different channels and cause the repeater to reconfigure to relay data signals between a second base station and the handset using the second channel. The second channel includes a frequency band. Related apparatus, systems, techniques and articles are also described.
