LTE Baseband Resource Pool for RACH Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LTE base stations face insufficient RACH processing capability, which cannot be effectively extended using existing baseband resource pool technologies that only implement resource sharing within a baseband processing module or between modules through redundant data exchange.
Innovation Solution
A method and apparatus for implementing a baseband resource pool in an LTE base station, where a main control module configures load sharing information and modifies PRACH configuration parameters to enable RACH resource allocation policies, allowing master and slave boards with baseband processing modules to perform PRACH detection in time division or frequency division modes, or detect different preamble root sequences, thereby extending RACH processing capability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing baseband resource pool technologies are used to implement resource sharing within a baseband processing module, then resource utilization is improved, but RACH processing capability cannot be extended between baseband boards
Solution Approach 1:
The patent segments the RACH processing function from the traditional baseband processing module and creates an independent RACH processing module. This segmentation allows the RACH processing capability to be independently configured and extended between baseband boards, resolving the contradiction by enabling both resource sharing (through the pool mechanism) and capability extension (through independent module deployment across multiple boards).
Solution Approach 2:
The patent introduces a baseband resource pool as an intermediary layer between multiple baseband boards and the RACH processing module. This resource pool acts as a mediator that manages and allocates RACH processing resources dynamically, enabling resource sharing while allowing the system to scale RACH processing capability across multiple boards without being constrained by individual module limitations.
2Quantity of substance
If the number of users in a cell increases to support more online and handover users, then service capacity is improved, but baseband RACH processing capability becomes insufficient
Solution Approach 1:
The patent creates a universal RACH processing module that can serve multiple cells and handle RACH processing for a large number of users. This module is designed with multi-functionality to manage RACH operations across different scenarios (online users, handover users, new access users), enabling the system to support increased user quantities without proportionally increasing per-cell processing complexity.
Solution Approach 2:
The patent extends the RACH processing capability from a single baseband board dimension to a multi-board dimension by deploying RACH processing modules across multiple baseband boards. This dimensional extension allows the system to handle increased user loads by distributing RACH processing tasks across multiple processing units, effectively scaling the processing capability to match the increasing number of users.
3Productivity
If baseband processing capability is increased to meet new feature requirements, then processing performance is improved, but existing investments are wasted and service impacts occur
Solution Approach 1:
The patent implements a dynamic baseband resource pool that can flexibly allocate and adjust RACH processing resources based on actual network conditions and service requirements. This dynamic mechanism allows the system to adapt processing capability to match demand, improving processing performance when needed while maintaining service continuity during transitions, thus avoiding the need for rigid over-provisioning that would waste investments and disrupt services.
