“…A message-based sharing technique should specify how to implement the control channel required for coexistence message exchange, and what information to share with other TVBDs. Among the techniques proposed in the literature for message-based sharing are [12], [13] and [14]. In [12] a common spectrum coordination channel (CSCC) is proposed in which a common channel at the edge of the used band is reserved for sending coexistence information such as the node ID, center frequency, bandwidth, transmit power, data rate, interference margin etc., which can be used by neighboring nodes to coordinate and adapt their transmission for better sharing.…”

Abstract-The FCC recently issued the regulatory rules for cognitive radio use of the TV white space spectrum. These new rules provide an opportunity but they also introduce a number of technical challenges. The challenges require development of cognitive radio technologies like spectrum sensing as well as new wireless PHY and MAC layer designs. These challenges include spectrum sensing of both TV signals and wireless microphone signals, frequency agile operation, geo-location, stringent spectral mask requirements, and of course the ability to provide reliable service in unlicensed and dynamically changing spectrum. After describing these various challenges we will describe some of the possible methods for meeting these challenges.

“…Reference [3] introduce the notion of Coordinated Access Bands of spectrum to achieve limited coordination for spectrum sharing in a distributed way. Spectrum etiquette protocols that act as simple overlays over interfering devices such as bluetooth and 802.11a/b/g devices have been studied in [9]. While [3], [9] have mostly focused on the network architecture and protocol signaling, this paper studies the spectrum allocation problem from an analytical standpoint.…”

We develop a system model where multiple service providers (SPs), in the same geographic region, share a fixed spectrum, on a non-interference basis. This spectrum is allocated to end-users for transmission to the SPs. We assume that a user can obtain service from all the SPs. The quality of service depends on system parameters such as number of users and SPs, the channel conditions between the users and SPs and the total transmit power of each user. We adopt a user utility maximization framework to analyze this system. We introduce a spectrum price that enables a simple distributed spectrum allocation with minimal coordination among the SPs and users. Given the user utility functions and the system parameters, we characterize the spectrum price and the optimal bandwidth that the users should obtain.

“…The etiquette approach is capable of operating in more complex scenarios than the reactive schemes. The Common Spectrum Coordination Channel (CSCC) variant of the etiquette approach is given in [24,25] together with the demonstration of proof-of-concept experiments for coexisting IEEE 802.11b/g and Bluetooth networks in the shared 2.4 GHz unlicensed band. Paper [26] proposes an internetwork spectrum coordination across Wi-Fi and LTE systems based on an ontological framework as a possible solution for improved coexistence.…”

-Mobile communication networks are constantly evolving, and each new generation provides considerably higher data transmission capabilities. Having in mind predictions of high cellular data traffic growth over the next few years, it is clear that the licensed band communications would have problems to support such a high bandwidth demand. One of the possible solutions to this problem is to adaptively use some additional spectrum out of the dedicated licensed band, such as the unlicensed bands. LTE-A standard introduced a new mechanism, named Carrier Aggregation, which provides the possibility to simultaneously use multiple frequency bands, such as the licensed and unlicensed bands. In order to work in an unlicensed band, LTE has to employ some new procedures that provide shared access with other systems using the same frequency band, such as WiFi. These procedures include spectrum sensing, dynamic frequency selection, as well as the coordination of the shared access. Performance measurements and the analysis of the procedures in 5 GHz frequency band will be shown in this paper. Since there is no available LTE hardware operating in 5 GHz band, it has to be made in a laboratory using the software radio approach. The description of such an experiment may be complex, and therefore we describe and propose the concept of the automatic experiment code generation. The automatic code generation is based on the semantic descriptions of experiments, and it is flexible due to the adoption of the domain and system ontologies for formal representation of the semantics of the problem.
