Duplex Barring Information for Radio Network Node Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Legacy radio network nodes struggle to efficiently serve User Equipments (UEs) with different duplex operational capabilities, leading to inefficient resource allocation and potential data loss or missed scheduling due to the lack of mechanisms to handle UEs supporting various duplex modes, especially in mixed environments with limited resources.
Innovation Solution
Implementing a duplex barring mechanism where radio network nodes transmit duplex barring information (DBI) to indicate whether a UE can access a cell based on its supported duplex operational modes, allowing the network to bar access to cells that cannot efficiently serve certain duplex operations and directing UEs to more suitable cells.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If legacy radio network nodes serve UEs with different duplex operational capabilities, then network coverage is maintained, but resource allocation efficiency deteriorates and data loss occurs
Solution Approach 1:
The patent segments the cell access based on duplex operational capability by introducing duplex barring information that differentiates between UEs supporting full duplex and half duplex modes. This segmentation allows legacy network nodes to efficiently allocate resources by preventing incompatible UEs from accessing cells where they would cause scheduling conflicts and data loss.
Solution Approach 2:
The patent introduces duplex barring information as an intermediary mechanism between the network node and UE. This intermediary element conveys the network's capability status regarding duplex operation, enabling UEs to make informed access decisions without requiring the network to actively manage and coordinate every duplex-specific resource allocation detail.
2Productivity
If the network bars access for UEs supporting certain duplex modes, then resource allocation efficiency improves, but UE access opportunities deteriorate
Solution Approach 1:
The patent applies local quality by providing duplex barring information specific to each cell's capabilities. Rather than uniformly barring all UEs, the network selectively bars only those UEs whose duplex capabilities are incompatible with the specific cell's configuration, while allowing access to UEs whose capabilities match the cell's capabilities.
Solution Approach 2:
The patent implements feedback by having the network node transmit duplex barring information to UEs about cell access restrictions. This feedback mechanism allows UEs to understand why certain cells are inaccessible and directs them to appropriate cells where their duplex capabilities are supported, maintaining access opportunities in suitable environments.
3Productivity
If legacy network nodes attempt to schedule all UE types, then network utilization increases, but scheduling conflicts and data loss increase
Solution Approach 1:
The patent applies preliminary action by having the network node determine and communicate duplex barring information before the actual scheduling process begins. This preliminary identification of incompatible UEs prevents scheduling conflicts from arising in the first place, allowing the network to achieve high utilization by scheduling only compatible UE types in each cell.

AI summary
It is herein disclosed a method performed by a radio network node (13) for handling communication in a wireless communications network. The radio network node transmits an indication indicating duplex barring information (DBI) associated with or related to at least one duplex operational mode (DOM) of a UE (10), wherein the DBI for a cell indicates whether the UE (10) supporting the at least one DOM can access the cell, or not.
