The frames are assigned for sole use by a base station on a frame-by-frame basis using a Frame-Based, On-Demand Spectrum Contention process. The process resolves contentions for use of frames using equally probable random numbers. The results of the process are transmitted and received between base stations using vector messages. Applications of the methods and systems include Wireless Regional Area Networks (WRANs), including those using the standards of IEEE 802.22."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Frame based, on-demand spectrum contention protocol vector messaging","description":"Systems and methods are disclosed by which base stations with overlapping service areas allocate frames within superframes of a channel in a cognitive radio communication network.
