Beam-Specific Network Admission for Less Congested Cell Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face inefficiencies in resource utilization due to uniform management of beams, leading to high energy consumption and underutilization of system resources, as some beams may have varying traffic loads while others are congested.
Innovation Solution
Implementing beam-specific network admission by indicating, via control signaling, whether a user equipment (UE) can access a cell through specific beams, allowing access through non-congested beams, and providing access barring parameters on a per-beam basis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If uniform management of beams is implemented, then system simplicity is maintained, but resource utilization efficiency deteriorates due to high energy consumption and underutilization of system resources
Solution Approach 1:
The patent segments the cell into multiple beams and applies independent access barring parameters to each beam. The network entity transmits separate barring parameters for different beams, allowing UEs to select appropriate beams based on congestion status. This segmentation enables differentiated resource management across beams while maintaining overall system coordination.
Solution Approach 2:
The patent implements local quality by applying different access barring parameters to different beams within the same cell. Each beam can have its own congestion status and barring parameter, allowing the system to optimize resource allocation locally for each beam while maintaining global network coordination. This enables less congested beams to be utilized while congested beams are appropriately restricted.
2Ease of operation
If access barring is applied uniformly across all beams, then network control is simplified, but resource utilization deteriorates due to inability to access less congested beams
Solution Approach 1:
The access barring control is segmented from cell-level to beam-level. Instead of a single cell-wide barring parameter, the network entity transmits multiple beam-specific barring parameters. UEs receive and process these segmented parameters to make informed beam selection decisions, improving access efficiency while maintaining manageable network control through standardized signaling procedures.
Solution Approach 2:
The patent introduces dynamic beam selection based on current congestion conditions. UEs can dynamically choose which beam to access by comparing the barring parameters received for different beams. This dynamic adaptation allows the system to respond to changing traffic conditions while maintaining simple network control through periodic updates of barring parameters.
3Device complexity
If UEs are restricted to single beam access, then access control is simplified, but resource utilization deteriorates due to inability to switch to less congested beams
Solution Approach 1:
The patent enables dynamic beam selection where UEs can switch between beams based on congestion status. The network entity provides barring parameters for multiple beams, and UEs dynamically select the most appropriate beam for access. This dynamic approach maintains simplified access control procedures while significantly improving beam selection flexibility and resource utilization.
Solution Approach 2:
The system implements feedback through the transmission of beam-specific barring parameters to UEs. UEs use this feedback information to make informed decisions about which beam to access. The network entity continuously updates these parameters based on congestion monitoring, creating a feedback loop that improves resource utilization while maintaining simple access control for UEs.

AI summary
Methods, systems, and devices for wireless communications are described. The network may manage access to a cell on a per-beam basis. The network may indicate, for a given beam, whether a user equipment (UE) is able to access the cell via the given beam. Accordingly, the UE may access a cell using a beam that is not barred for the UE. In some examples, control signaling may include a list of each beam associated with the cell and may indicate whether each beam is barred or accessible. In some examples, control signaling include a field indicating whether the particular beam on which the control signaling was transmitted is barred. In some examples, control signaling may indicate whether a cell is barred. The UE may interpret the indication of whether the cell is barred as indicating whether the beam on which the control signaling was transmitted is barred.
