Radio Resource Allocation via Dual Buffer Status Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, errors in buffer status reports and channel resource requests by user equipment lead to inefficient allocation of radio resources, resulting in failed communication due to unallocated resources despite data to be transmitted.
Innovation Solution
A method where user equipment requests radio resources using a first and second allocation request mode, with a buffer status report triggering a second report if allocation information is not received within a predetermined time, utilizing either a scheduling request channel or a random access procedure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user equipment uses a single buffer status report mechanism, then the protocol is simple, but errors in reporting lead to failed communication and inefficient resource allocation
Solution Approach 1:
The patent implements preliminary actions by having the user equipment transmit a first buffer status report before actual data transmission begins. This allows the base station to allocate radio resources in advance based on the reported buffer status, ensuring that resources are ready when needed and reducing the likelihood of communication failure due to unallocated resources.
Solution Approach 2:
The patent establishes a feedback mechanism where the user equipment transmits buffer status reports to the base station, which then uses this information to allocate radio resources. The base station sends allocation information back to the user equipment, creating a closed-loop feedback system that ensures reliable resource allocation and allows for correction of any errors in the initial reporting.
2Productivity
If radio resources are allocated without timely buffer status reports, then allocation speed is fast, but communication efficiency decreases due to unallocated resources
Solution Approach 1:
The patent applies preliminary action by requiring the user equipment to transmit buffer status reports before data transmission begins. This allows the base station to perform resource allocation in advance, ensuring that radio resources are ready when data needs to be transmitted, thereby avoiding delays and improving overall communication efficiency.
Solution Approach 2:
The patent ensures continuity of useful action by implementing a mechanism where the user equipment continuously monitors its buffer status and transmits reports as needed. The base station continuously allocates resources based on these reports, creating an ongoing process that maintains efficient communication without interruption or resource waste.

AI summary
A method of allocating radio resources in a wireless communication system is disclosed. In one aspect of the present invention, in a wireless communication system, a user equipment requests a base station to allocate radio resources for uplink data transmission of at least one time in accordance with a first radio resource allocation request mode. The user equipment requests the base station to allocate the radio resources for uplink data transmission in accordance with a second radio resource allocation request mode if a predetermined condition is satisfied.
