摘要： In order to satisfy the conflicting requirements for spectrum sensing and QoS of data transmission, it is highly desirable for a cognitive radio system, e.g. IEEE 802.22 WRAN, to perform spectrum sensing and data transmission simultaneously. Embodiments of the invention address critical issues of self-interference generated from a transmission unit to the co-located sensing unit when the simultaneous sensing and data transmission technique is applied. A number of interference mitigation techniques are described and analysis are given.

摘要： Discovery of safety and non-safety capable single-radio devices in vehicular wireless environments is made possible through the use a two-bit indicator. A first indicator is associated with a type C device. A second indicator is associated with a non-type C device within one hop of a type C device. A third indicator is associated with a non-type C device within two hops of a type C device. A fourth indicator is associated with a non-type C device within three hops or more (out of range) of a type C device. Discovery of safety and non-safety capable single-radio vehicular devices within a protection range in multiple-channel based wireless vehicular environments is thus made possible.

摘要： 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.

摘要： 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.

摘要： Data service transmission interruption is minimized by initially setting up a cluster of channels to transmit data services. As the need arises to switch channels due to the detection of an incumbent signal, the data services can be switched with substantially no delay. A group of channels from those available in a wireless network are chosen to form a cluster of channels. Each channel within the cluster is set up to convey data services with channel parameters being stored. A first operating channel is chosen from among the cluster of channels to transmit the data services. While the data services are being transmitted on the first operating channel, out-of-band spectrum sensing occurs on the other channels. Upon predetermined criteria a channel switch occurs. As each channel has already been set up the necessary channel parameters are retrieved from storage and restored without data service interruption.

摘要： A self-coexistence window reservation protocol for a plurality of Wireless Regional Area Network (WRAN) cells operating in a WRAN over a plurality of channels includes a sequence of self-coexistence windows that uniquely identifies a transmission period for each WRAN cell. A self-coexistence window reservation protocol is included within the first packet of a Coexistence Beaconing Protocol period identifying when each WRAN cell associated with a particular channel will transmit. When not actively transmitting, a WRAN cells remains in a passive, receiving mode to accept data. As the transmissions of each WRAN cell operating on a particular channel are scheduled, contention for a transmission period is eliminated.
