Dynamic Data Packet Transmission Regime Modification for Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless telecommunications networks, user equipment faces challenges in maintaining data packet transmission regimes, particularly when power limited, leading to reduced geographical coverage and data throughput, as existing methods struggle to efficiently transition between different transmission time intervals without causing service disruptions.
Innovation Solution
A method is introduced to dynamically modify user equipment data packet transmission regimes by adjusting the period of retransmissions and involving a radio network controller to propagate changes across the active set of base stations, allowing for seamless transitions between normal and coverage extension modes, ensuring continuous service and optimal data throughput.

1Productivity
If user equipment operates in a 2ms transmit time interval regime to increase data throughput, then data throughput is improved, but the geographical coverage area supported by a base station is reduced due to power limitations
Solution Approach 1:
The patent implements dynamic switching between 2ms and 10ms transmit time interval regimes based on power availability and coverage requirements. The system can transition from a high-throughput 2ms regime to a broader-coverage 10ms regime when power limits are reached, and vice versa when power is available, allowing optimal adaptation to changing conditions without manual intervention
Solution Approach 2:
The patent changes the transmission parameter (transmit time interval duration) from fixed to variable. By adjusting the TTI duration between 2ms and 10ms based on power constraints and coverage needs, the system optimizes the trade-off between data throughput and geographical coverage area, enabling the same base station to serve different operational modes as conditions change

If user equipment transitions back to a 10ms transmit time interval regime when power limit is reached, then coverage area is maintained, but data throughput is reduced
Solution Approach 1:
The system dynamically adjusts the transmit time interval regime based on real-time power availability and coverage requirements. When power limits are reached, the system transitions to a 10ms regime to maintain coverage, and when power becomes available, it switches back to a 2ms regime to maximize throughput, creating a responsive adaptive system that optimizes both coverage and performance throughout operation
Solution Approach 2:
The transmission time interval parameter is made changeable between 2ms and 10ms based on operational conditions. This parameter adjustment allows the system to maintain coverage area by switching to longer intervals when power is constrained, while preserving the option to return to shorter intervals for higher throughput when power availability improves
3Area of stationary object
If user equipment uses coverage extension transmission modes to extend geographical coverage, then coverage area is improved, but the complexity of coordinating multiple base stations increases
Solution Approach 1:
The patent implements feedback mechanisms where user equipment monitors power levels and coverage conditions, then communicates with the serving base station to request regime changes. The base station coordinates with non-serving base stations in the active set, sharing transmission regime information so all stations can properly decode packets. This feedback loop manages the complexity by automating the coordination process rather than requiring manual configuration
Solution Approach 2:
The patent segments the base station network into a serving base station and non-serving base stations in an active set, each with specific roles. The serving base station manages the transmission regime changes, while non-serving base stations receive notifications and adjust their decoding accordingly. This segmentation allows coverage extension functionality to be implemented without requiring all base stations to participate equally in every decision, reducing overall system complexity

AI summary
A method of notifying a set of base stations in a wireless telecommunications network of a modification to a data packet transmission regime. A radio network controller and computer program product operable to carry out that method. The data packet transmission regime comprises predetermined periodic retransmission of a given data packet and said modified data packet transmission regime comprises a change to the predetermined period of retransmission. The method comprises the steps of: receiving at least one indication of a change request to modify a data packet transmission regime between user equipment and a base station; notifying a set of base stations identified as having an active radio link with said user equipment for which an indication of change request has been received of said modification to said data packet transmission regime.
