RRC Entity Selection for Signaling Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, particularly in new radio (NR) and 5G technologies, face challenges in efficiently managing radio resource control (RRC) messages due to limitations in link and entity selection, which can lead to delays and inefficiencies in data transmission, especially in dual connectivity scenarios.
Innovation Solution
The introduction of a secondary RRC entity at both the user equipment (UE) and the network, along with the ability to select between multiple RRC links for transmitting RRC messages, allows for dynamic routing of signaling messages, reducing delays and improving flexibility in data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single RRC entity and link are used for RRC message transmission, then device complexity is reduced, but transmission delays increase and efficiency deteriorates
Solution Approach 1:
The patent segments the RRC functionality by introducing multiple RRC entities (first RRC entity and second RRC entity) at both the network side and UE side. Each RRC entity is associated with a specific RRC link, allowing independent management and selection of communication paths. This segmentation enables parallel RRC message transmission through multiple links, improving transmission efficiency while maintaining manageable complexity through modular entity design.
2Adaptability or versatility
If multiple RRC entities and links are introduced, then transmission flexibility and efficiency improve, but device complexity increases
Solution Approach 1:
The patent implements dynamic RRC link selection mechanisms where the UE can select between first and second RRC links based on current network conditions, message types, and entity availability. The system dynamically configures and activates appropriate RRC entities and links as needed, rather than maintaining all entities in a fixed state. This dynamic approach provides transmission flexibility while managing complexity through on-demand activation and conditional configuration.
3Loss of time
If RRC messages are transmitted through the master link only, then entity management is simplified, but transmission delays increase
Solution Approach 1:
The patent introduces a second RRC link as an intermediary communication path alongside the traditional master link. The second RRC link serves as an alternative route for RRC message transmission, allowing messages to bypass congestion or delays on the master link. The system includes mechanisms to select between the master link and second link based on current conditions, adding minimal complexity while significantly reducing transmission delays through parallel path availability.

AI summary
Certain aspects of the present disclosure relate to methods and apparatus for radio resource control (RRC) entity selection for RRC messages using communications systems operating according to new radio (NR) technologies. Certain aspects provide a method for wireless communication. The method generally includes selecting an RRC entity from a plurality of RRC entities for communicating a RRC message, wherein the plurality RRC entities cooperate to manage radio resources of the UE. The method also includes selecting a link associated with the RRC entity for communicating the RRC message, and transmitting an uplink signaling transmission using the link to the RRC entity.
