Telecommunications Repeater Node Pilot Signal Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing telecommunications systems using repeater nodes face challenges in efficiently identifying the most appropriate repeater node for mobile devices to communicate with, leading to increased power consumption and radio interference due to continuous pilot signal broadcasting on separate channels.
Innovation Solution
A system where each repeater node transmits a pilot signal at reduced power during a specified time slot, including an identifier, allowing mobile devices to select the strongest signal and reduce power consumption by only receiving data during allocated time slots, thereby minimizing radio interference and complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If repeater nodes continuously broadcast pilot signals on separate channels to enable mobile devices to identify the strongest signal, then mobile devices can select the most appropriate repeater node, but power consumption increases and radio interference worsens
Solution Approach 1:
The patent implements periodic pilot signal transmission within a time division multiplexing framework, where each repeater node transmits pilot signals only during its allocated time slot rather than continuously. This periodic action reduces power consumption while maintaining the ability for mobile devices to identify and select the strongest repeater node signal.
Solution Approach 2:
The patent merges the pilot signal transmission with the existing time division multiplexing data transmission framework, eliminating the need for separate continuous pilot channels. By combining these functions into a unified time-slotted structure, the system reduces radio interference and power consumption while maintaining reliable repeater node identification.
2Reliability
If repeater nodes continuously broadcast pilot signals on separate channels, then mobile devices can identify the strongest signal, but radio interference increases
Solution Approach 1:
The patent merges pilot signal transmission with data transmission by using the same radio channel and time division multiplexing structure. This eliminates separate continuous pilot channels that would cause interference, while still enabling reliable repeater node identification through periodically transmitted pilot signals within allocated time slots.
Solution Approach 2:
By implementing periodic pilot signal transmission only during allocated time slots rather than continuous broadcasting, the system reduces radio interference while maintaining the reliability of repeater node selection. The periodic nature ensures that pilot signals are present when needed but do not continuously occupy the spectrum.
3Reliability
If repeater nodes transmit pilot signals continuously, then mobile devices can maintain accurate repeater node identification, but system complexity increases
Solution Approach 1:
The patent combines pilot signal transmission and data transmission into a unified time division multiplexing structure, eliminating the need for separate continuous pilot channels and reducing transceiver unit complexity. The same hardware infrastructure handles both functions by time-multiplexing them.
Solution Approach 2:
The time division multiplexing structure serves multiple functions: it transmits both data and pilot signals using the same radio channel and infrastructure. This multi-functionality reduces system complexity while maintaining accurate repeater node identification through the integrated approach.
4Reliability
If each repeater node transmits data continuously, then data transmission reliability is maintained, but power consumption of repeater nodes increases
Solution Approach 1:
The patent implements time division multiplexing where each repeater node transmits data only during its allocated time slot rather than continuously. This periodic transmission maintains data reliability through structured time slots while significantly reducing the power consumption of repeater nodes.
Solution Approach 2:
While transmission is periodic rather than continuous, the system maintains continuity of useful action by ensuring that each repeater node has a guaranteed time slot for transmission, and the time division multiplexing structure ensures uninterrupted data flow across the network through coordinated time slots.

AI summary
A telecommunications system for communicating data to and from a mobile device. The system comprises a plurality of repeater nodes disposed to form a network. Each repeater node has a transceiver unit operable to transmit the data with a first transmission power to one or more other of the repeater nodes within one of a plurality of slots of a time frame. Each repeater node is allocated a time slot, and the mobile device is arranged to transmit and receive data to and from the repeater nodes in the network. Each of the repeater nodes is operable to transmit a pilot signal during the same one of the time slots of the time frame with a second transmission power, the second power being less than the first transmission power. The pilot signal includes an identifier of the repeater node which is transmitted with the pilot signal and the mobile device is operable to receive one of the pilot signals and from the identifier included in the strongest pilot signal the mobile device can identify on of the repeater nodes to which to transmit and or receive data.
