Service Flow Indicator for Wireless Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, the lack of information exchange on resource grant starting points during service flow generation or modification leads to packet transmission delays and losses, as user equipment must wait for resource allocation from the base station.
Innovation Solution
The method involves the user equipment transmitting an indicator and a resource allocation request starting point to the base station during service flow generation or modification, allowing for proactive resource allocation and reducing delays and losses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the base station and user equipment do not exchange information on resource grant starting point during service flow generation, then the service flow generation procedure is simple, but packet transmission delay and packet loss occur
Solution Approach 1:
The patent applies preliminary action by having the user equipment indicate the resource grant starting point during service flow generation or modification. This allows the base station to allocate resources in advance at the indicated starting point, eliminating the need for separate resource request procedures and ensuring resources are ready before data transmission begins, thus preventing packet loss and delay while maintaining procedural simplicity
2Ease of operation
If the user equipment waits for base station resource allocation after service flow generation, then the resource allocation process is straightforward, but packet transmission delay increases
Solution Approach 1:
The user equipment performs preliminary action by indicating the resource grant starting point during service flow generation. This enables the base station to proactively allocate resources at the indicated time without waiting for separate resource requests, thereby reducing packet transmission delay while keeping the resource allocation process straightforward through existing signaling mechanisms
3Measurement precision
If separate resource request procedure is performed after service flow generation, then resource allocation can be precise, but packet loss may occur
Solution Approach 1:
The patent merges the service flow generation procedure with the resource request procedure by having the user equipment indicate the resource grant starting point during service flow generation or modification. This combination eliminates the need for separate resource request procedures while maintaining precise resource allocation at the indicated starting point, thereby preventing packet loss without sacrificing allocation precision
