Abstract: Radio frequency (RF) architectures for spectrum access networks are provided. Embodiments of the invention generally provide a radio frequency (RF) architecture for customer premise equipment (CPE) for use in, for example, IEEE 802.22 wireless regional area networks (WRANs). In some embodiments, the CPE RF architecture includes two receive chains with a directional antenna and an omni-directional antenna, respectively. The CPE RF architecture facilitates opportunistic out-of-band spectrum sensing and WRAN signal receiving that are performed in parallel with data transmission.

Abstract: The invention relates to systems and methods for spectrum sharing and communication among several wireless communication networks with overlapping service areas (or cells), especially to Wireless Regional Area Networks (WRANs). Particular embodiments of the invention disclose using a conference channel to communicate between base stations. Other embodiments use slotted coexistence windows within frames to transmit and receive information, including for reserving transmission times within subsequent frames.

Abstract: 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. 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.
