Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, relay user equipment often wastes resources by transmitting the same data multiple times to remote user equipment, leading to inefficiencies in data transmission, especially when the base station uses multicast mode with few relay user equipments, resulting in high power consumption and resource waste.
Innovation Solution
A method where a first network device triggers a relay user equipment to establish a common data flow bearer with a second network device, sending an identifier of the common data flow to remote user equipment, allowing downlink data to be transmitted once from the relay user equipment to multiple remote user equipments, thereby reducing redundant data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a relay user equipment provides relay services for multiple remote user equipments in unicast transmission manner, then the relay user equipment can serve multiple remote user equipments, but the same data is repeatedly transmitted multiple times between the relay user equipment and network side, causing resource waste
Solution Approach 1:
The patent merges multiple unicast data flows into a single multicast data flow. When the network device determines that multiple remote user equipments require the same data, it establishes a multicast bearer instead of multiple unicast bearers, combining the transmission resources into one shared channel that serves all target user equipments simultaneously.
Solution Approach 2:
The patent implements dynamic switching between unicast and multicast transmission modes. The network device dynamically determines the appropriate transmission mode based on real-time conditions such as the number of remote user equipments, data characteristics, and network state, transitioning from static unicast to dynamic multicast when beneficial.
2Area of stationary object
If the base station transmits data in multicast mode to ensure farthest user equipment can receive data, then coverage is improved, but power consumption increases and resource waste occurs when there are few relay user equipments
Solution Approach 1:
The base station dynamically adjusts transmission mode between unicast and multicast based on the number of relay user equipments and network conditions. When few relay user equipments are available, unicast mode is used to conserve power; when multiple relay user equipments exist, multicast mode is activated to improve coverage efficiency and reduce overall resource consumption.
Solution Approach 2:
The patent changes the transmission mode parameter based on network conditions. The network device monitors parameters such as the number of relay user equipments and data characteristics, then adjusts the transmission mode parameter accordingly, switching from power-intensive multicast to energy-efficient unicast when appropriate.
3Reliability
If unicast transmission is used for each remote user equipment, then dedicated data transmission is ensured, but transmission efficiency decreases when same data needs to be sent to multiple remote user equipments
Solution Approach 1:
The patent combines multiple identical data transmissions into a single multicast transmission. When the network device identifies that the same data needs to be delivered to multiple remote user equipments, it merges the transmission paths and uses one multicast data flow to reach all targets, maintaining data reliability while dramatically improving transmission efficiency.
Solution Approach 2:
The multicast data flow serves multiple functions simultaneously, delivering the same data to multiple remote user equipments through a single transmission channel. This universal approach allows one data flow to fulfill multiple delivery requirements, enhancing efficiency without compromising the reliability of data reception at each individual user equipment.
