Autonomous Paging Resource Allocation in Wireless Backhaul

Solution Overview

Problem

Existing wireless backhaul networks face challenges in efficiently allocating resources for paging messages, leading to potential delays in traffic communication between nodes.

Innovation Solution

The system allows a wireless node to identify and autonomously use resources controlled by another node in the network for transmitting paging messages, with the option to request resources if autonomous transmission is disabled.

1Object-affected harmful factors

If resources are partitioned and allocated to different nodes for access and backhaul communications, then interference is minimized, but resource utilization efficiency decreases and communication delays increase

Solution Approach 1:

The patent implements dynamic resource allocation where the first node can request and use resources from the second node on a per-message basis. The resource allocation transitions from static/partitioned to dynamic/shared, allowing the first node to autonomously access paging resources controlled by the second node when needed, thereby improving resource utilization efficiency while maintaining interference management through controlled access mechanisms.

Engineering Contradiction:

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent implements preliminary resource configuration where the second node is pre-configured with paging resources and the first node has pre-established the capability to request and use these resources autonomously. When a paging message needs to be transmitted, the first node can immediately access the pre-configured resources without going through complex real-time allocation procedures, thereby reducing communication delays while maintaining optimized communication between nodes.

Solution Approach 2:

The patent enables the first node to autonomously determine when to use resources controlled by the second node and to autonomously transmit paging messages without requiring explicit resource allocation requests or approvals in real-time. This self-service mechanism maintains resource control through pre-established configurations while dramatically improving transmission speed by eliminating real-time coordination overhead.

AI summary

Methods, systems, and devices for wireless communications are described that provide a mechanism for a wireless node to identify resources that are controlled by a different wireless node in the wireless backhaul communications network and in some cases autonomously transmit certain transmissions using resources of the different wireless node. A first wireless node may receive signaling that indicates whether such transmissions may be autonomously transmitted via configuration information or a flag provided in signaling to the first wireless node. The first wireless node may in some cases determine that autonomous transmissions are enabled based on a type of communication or node that provides the information for the transmissions from the first wireless node. In some cases, a priority associated with the transmissions may be used to determine whether autonomous transmissions are enabled.
