Enhanced MAC Control Element Bit Rate Query for High Data Rates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication technologies, such as LTE and 5G, face challenges in supporting higher data rates required for advanced streaming services like HD and UHD video, as conventional bit rate query mechanisms are limited, failing to accommodate the increased bandwidth needs for applications like virtual reality and high-quality video streaming.
Innovation Solution
The proposed solution involves a query and response mechanism using enhanced media access control (MAC) control elements, which include a bit rate field and additional bits or multipliers to support higher data rates, allowing for bit rates up to 24 Gbps, enabling higher data rate requests through MAC control elements in uplink and downlink streaming scenarios.

Engineering Contradiction Analysis
1Adaptability or versatility
If conventional bit rate query mechanisms are used, then system compatibility is maintained, but data rate support is limited and cannot accommodate advanced streaming services
Solution Approach 1:
The bit rate query mechanism is segmented into multiple components: a base bit rate field and additional bits that can be selectively activated. When advanced streaming services are detected, the system segments the bit rate representation into a base component and an extended component, allowing high bit rates to be expressed as base rate plus offset without requiring complete restructuring of the MAC control element.
Solution Approach 2:
The patent adds an additional dimension to the bit rate representation by introducing extra bits that extend the dynamic range. Instead of simply increasing the bit rate field width, the solution adds a new dimension through optional extension bits that are activated based on service type, effectively creating a multi-level bit rate encoding scheme that maintains backward compatibility while supporting ultra-high bit rates up to 24 Gbps.
2Adaptability or versatility
If MAC control elements are enhanced to support higher data rates, then streaming service capability is improved, but backward compatibility may be compromised
Solution Approach 1:
The MAC control element structure is made dynamic through conditional activation of extension bits. The system dynamically adjusts the bit rate encoding format based on the detected service type: conventional formats are used for legacy services to ensure compatibility, while extended formats with additional bits are activated only when advanced streaming services are identified, thereby maintaining reliability for existing devices while enabling enhanced capability for supported services.
Solution Approach 2:
The enhanced MAC control element is designed with multi-functionality to serve both conventional and advanced streaming services. The bit rate field can operate in two modes: standard mode for legacy compatibility and extended mode for high-performance streaming. This universal design allows the same control element structure to fulfill multiple functions across different service types and device capabilities, ensuring that the system can gracefully support a wide range of applications from basic video streaming to ultra-high-definition and virtual reality services.

AI summary
Certain aspects of the present disclosure provide techniques for an enhanced query and response message for a recommended bit rate for uplink and/or downlink streaming. The techniques generally include generating a query message indicating a requested data rate for streaming services, wherein the requested data rate is indicated via a bit rate field and one or more additional bits, and sending the query message to a base station.
