Unified Initial Access Channels for MBB and IoT Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face inefficiencies in transmitting common channels for both mobile broadband (MBB) and Internet of Things (IoT) devices, leading to increased power consumption, time, and resource usage due to the need for multiple repetitions to meet the requirements of both device types.
Innovation Solution
A unified initial access procedure is implemented, reducing the number of repetitions needed for configuring both MBB and LPWA UEs by using a common channel design that supports both device types, with separate configurations for specific device-type information, thereby optimizing resource allocation and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate common channels are configured for MBB and IoT devices, then device-specific requirements are met, but power consumption and resource usage increase
Solution Approach 1:
The patent implements a unified common channel that serves both MBB and IoT devices simultaneously. The channel is designed with multi-functionality to handle different device types without requiring separate dedicated channels, thereby reducing overall power consumption while maintaining device-specific performance requirements through configurable parameters within the unified channel structure.
Solution Approach 2:
The patent merges previously separate common channels for MBB and IoT devices into a single unified common channel. This consolidation eliminates redundant transmissions and resource allocations, reducing power consumption and resource usage while maintaining the ability to serve both device types effectively through a shared channel infrastructure.
2Length of stationary object
If multiple repetitions are used for common channel transmission, then coverage is extended, but time and resource consumption increase
Solution Approach 1:
The patent employs parameter changes within the unified common channel to optimize transmission efficiency. By dynamically adjusting parameters such as repetition count, transmission power, and resource allocation based on device type and channel conditions, the system achieves extended coverage without requiring excessive repetitions, thereby reducing time and resource consumption while maintaining coverage requirements.
3Loss of information
If device-type-specific channels are maintained, then information accuracy is improved, but system complexity increases
Solution Approach 1:
The patent segments device-specific information transmission within the unified common channel structure. By dividing the channel into logical segments or using segmentation techniques for different device types, the system maintains accurate device-specific information transmission while avoiding the complexity of completely separate physical channels. The segmentation allows targeted information delivery to specific device types without requiring complex overall system architecture.

AI summary
Various aspects of the present disclosure relate to techniques for using a unified initial access procedure. A network equipment (NE) is configured to configure, as part of an initial access procedure, a common channel that supports a plurality of device types and a device type common channel for a device type of the plurality of device types, wherein the plurality of device types comprises a first device type that supports mobile broadband (MBB) communication and a second device type that supports an internet of things (IoT) communication; transmit, in the common channel, a first portion of remaining minimum system information (RMSI) that is common for the plurality of device types; and transmit, in the device type common channel, a second portion of the RMSI and paging information that is specific to the device type.
