Base Station No Emission Mode Switching for ULE Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in reducing base station emissions while supporting ultra low energy (ULE) and no-emission mode (NEMo) devices, as the repetitive transmission of beacons required by ULE devices contradicts with the environmental-friendly NEMo operation, necessitating the disabling of NEMo mode, which is often not acceptable to customers.
Innovation Solution
A method and system for a base station to operate in a no-emission mode and switch to emission mode based on detected transmissions from wireless communication devices, allowing beacon transmission only when necessary, with the option to transmit different types of beacons to ULE and NEMo devices, including a hybrid beacon for controlling their behavior.

Engineering Contradiction Analysis
1Reliability
If the base station repetitively transmits ULE dummy bearers to support ULE devices, then ULE devices can achieve fast synchronization and communicate efficiently, but the base station cannot operate in NEMo mode and must continuously emit beacons
Solution Approach 1:
The base station dynamically switches between NEMo mode (low emission) and traditional beacon transmission modes based on real-time detection of ULE device presence and communication needs. This dynamic adaptation allows the system to minimize emissions when ULE devices are absent while ensuring reliable synchronization when they are present.
Solution Approach 2:
The base station uses feedback from detecting transmissions from wireless communication devices to determine whether to continue operating in NEMo mode or switch to emission mode. This feedback mechanism ensures that beacon transmission occurs only when necessary, balancing ULE device support requirements with emission reduction goals.
2Loss of energy
If the base station operates in NEMo mode to reduce emissions, then environmental friendliness and energy savings are improved, but the base station cannot communicate with ULE devices that require continuous beacon transmission
Solution Approach 1:
The base station operates dynamically, switching between NEMo mode (for energy savings when no ULE devices are present) and traditional beacon transmission modes (when ULE devices need communication). This dynamic operation allows the system to achieve both energy efficiency and device compatibility as needed.
Solution Approach 2:
The base station changes its operational parameters (beacon transmission status) based on detected conditions. When ULE devices are detected, the base station transitions from NEMo mode parameters to traditional beacon transmission parameters, enabling compatibility while maintaining energy efficiency during NEMo operation.
3Reliability
If the base station continuously transmits beacons to maintain communication with ULE devices, then communication reliability is improved, but the base station cannot achieve NEMo compliance and environmental friendliness
Solution Approach 1:
Instead of continuous beacon transmission, the base station uses periodic action by transmitting beacons only when NEMo mode is exited due to ULE device presence. The base station periodically monitors for ULE device transmissions and activates beacon mode only when necessary, reducing overall emission while maintaining communication reliability when devices are present.

AI summary
A method that includes operating a base station at a first operational mode thereby preventing the base station from a periodically transmitting a beacon; detecting, by the base station, a transmission from a first wireless communication device; determining, by the base station and in response to the transmission from the first wireless communication device, whether to continue operating in the no emission mode or to enter a emission mode during which the base station is allowed to transmit the beacon; and entering the second operational mode, if it is determined to enter the second operational mode, and sending the beacon to the first wireless communication device.
