UE Transmission Prioritization in Multi-Connectivity Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multiple connectivity wireless communications, user equipment (UE) faces challenges in prioritizing transmissions to multiple cells or cell groups due to power limitations, which affects the allocation of transmission resources and the ability to transmit data effectively across different communication links.
Innovation Solution
The UE determines whether to prioritize transmissions to primary and secondary cells by allocating transmission power and deciding on the transmission of transport block bits based on parameters such as channel content and power availability, allowing for concurrent transmissions across multiple cells.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the UE transmits communications to multiple cells or cell groups simultaneously, then the network coverage and communication reliability are improved, but the UE power consumption increases and transmission power allocation becomes complex
Solution Approach 1:
The patent segments the transmission power allocation into different priority levels and cell groups. The UE divides its limited power resources among multiple cells based on prioritization rules, where different cells or cell groups are assigned different priorities for power allocation. This segmentation allows the UE to manage power consumption effectively while maintaining communications with multiple cells simultaneously.
2Productivity
If the UE allocates transmission power to multiple cells, then the data transmission capability is improved, but the transmission power limitation is exceeded
Solution Approach 1:
The patent changes the parameter of transmission power allocation by introducing prioritization-based dynamic allocation. Instead of equal power distribution or fixed power allocation, the system dynamically adjusts transmission power parameters based on cell priority, communication requirements, and available power resources. This allows the UE to optimize data transmission capability within its power limitations by allocating more power to high-priority cells and less to lower-priority cells.
3Productivity
If the UE prioritizes transmissions to certain cells, then the transmission efficiency is improved, but the complexity of transmission management increases
Solution Approach 1:
The patent applies preliminary action by establishing prioritization rules and power allocation strategies in advance before actual transmissions occur. The UE pre-configures priority levels for different cells and pre-determines power allocation ratios based on expected communication requirements. This preliminary setup simplifies real-time transmission management by providing a framework that automatically guides power allocation decisions without requiring complex real-time calculations for each transmission.

AI summary
Certain aspects of the present disclosure relate to allocating transmission power in multiple connectivity wireless networks. A device can establish a first connection with a first primary cell in a first cell group as well as a second connection with a second primary cell in a second cell group. The device can determine whether to prioritize a first communication over the first connection or a second communication over the second connection, wherein the first communication and the second communication are scheduled for concurrent transmission. In addition, the device can transmit at least one of the first communication over the first connection or the second communication over the second connection in a transmission time interval based at least in part on determining whether to prioritize the first communication or the second communication.
