Techniques for controlling spectrum usage of a hierarchical communication system
摘要
說明書
Initially, the SAS Controller will require medium access budget requirements from the secondary systems in order to manage the spectral resources and allow access to the corresponding bands (e.g. MuLTEfire/WiFi APs will provide required resource requests). The requirements can be expressed in terms of bandwidth share, throughput (e.g. minimum throughput), application types (e.g., social media, personal email, youtube, etc.) or other performance requests.
To ensure truthfulness of the secondary systems and guarantee utilization and fairness of the spectrum distribution among the different systems, different incentive and allocation mechanisms can be used. A simple approach is to introduce a penalty to the secondary systems that do not completely use the allocated resources to prevent them from requesting for the entire bandwidth. Other approaches that can be used include auction-based mechanisms [4] or market-based approaches. For example, the required information that the CBSDs have to send to the SAS can be proportional to their resource requests. Hence, little additional information is required in case of low resource requests (e.g., a 1% resource request is granted easily) whereas more information is required for high resource requests (e.g., a 99% resource request required detailed information on application types, etc.).
