MAC-m MAC-hs Resource Coordination for Wireless Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile communication systems, the coexistence of MBMS and HSDPA leads to inefficient resource allocation due to delayed recognition of wireless resource variations, causing difficulties in scheduling high-priority data transmission and potential data delays.
Innovation Solution
The MAC-m notifies the MAC-hs of wireless resource information in advance, allowing the MAC-hs to calculate and allocate resources for HSDPA data, enabling proactive scheduling and reducing data transmission delays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless resources are allocated independently to MBMS and HSDPA without advance notification, then each service can manage its own resources, but wireless resource usage efficiency decreases and unused resources are generated
Solution Approach 1:
The MAC-m performs preliminary action by notifying the MAC-hs in advance of the wireless resource allocation status for MBMS data transmission. This advance notification enables the MAC-hs to proactively adjust its resource allocation strategy before the actual transmission occurs, allowing it to utilize previously unused wireless resources for HSDPA data, thereby improving overall resource usage efficiency while maintaining independent management of each service's resources
Solution Approach 2:
The invention implements a feedback mechanism where the MAC-m provides information about MBMS wireless resource usage to the MAC-hs. This feedback loop enables the MAC-hs to recognize variations in available wireless resources in advance and dynamically adjust its scheduling decisions, transforming the previously isolated resource management into a coordinated system that maintains operational independence while achieving better resource utilization
2Adaptability or versatility
If wireless resource information is not transmitted to the other MAC, then each MAC can control its own data communication, but scheduling of high-priority data becomes difficult and data transmission delays occur

AI summary
A communication control method is provided which improves a wireless resource usage rate, is available to recognize a variation in wireless resource state in advance, and is available to control communication in accordance with the variation in a mobile communication system in which an MBMS and an HSDPA coexist and the same wireless resource is shared and used. A MAC-m transmits information related to a wireless resource used on an MBMS transport channel at a transmission timing of a base station to a MAC-hs before the transmission timing. The MAC-hs receives the information related to the wireless resource of the MBMS transport channel from the MAC-m. The MAC-hs calculates a wireless resource which can be used applied to data of a HSDPA transport channel at the transmission timing with using the information related to the wireless resource of the MBMS transport channel and a wireless resource to which the HSDPA transport channel is allocated. The MAC-hs controls communication of the data in accordance with the wireless resource of the calculation result.
