Spectrum access system for the citizen broadband radio service

Abstract-Spectrum Access Systems (SAS) are emerging as a principal mechanism for managing the sharing of radio spectrum. The design of the SAS depends on the specification of spectrum property rights and the governance system by which those rights are enforced. Current perspectives on SAS design have been too limited, focusing narrowly on the technical components without adequate consideration of socio-technical factors that will impact the likely success of any SAS design.In this paper, we apply the social science literature on the management of common pool resources (CPR) to the design challenge for the SAS. Heretofore, too much of the discussion has focused on an overly simplistic characterization of the spectrum rights design space as a dichotomous choice between licensed v. unlicensed, markets v. government, and exclusive v. open. The CPR framework forces consideration of a wider class of design options, positioning the specifications of spectrum property rights more appropriately along a multi-dimensional continuum of rights bundles. The CPR framework highlights the importance of considering formal and informal, multi-layered institutional and market-based interactions among SAS stakeholders when designing a resource management system. We will explain how this leads one to view the SAS as a polycentric governance system (using the terminology in the CPR literature). By examining the economic and social context of spectrum sharing, we assert that these emerging systems must be sufficiently flexible to adapt to various forms of resource governance, which refers to the process by which rights are distributed among stakeholders, how those rights are enforced, and how the resource is managed. We illustrate how the insights from the CPR literature might be implemented in a prototype SAS architecture.

“…The SAS dynamically determines and assigns PAL channels and GAA frequencies at a given geographic location, controls the interference environment, and enforces exclusion zones to protect higher priority users as well as takes care of registration, authentication, and identification of user information [25]. In 2016, the FCC finalized rules for CBRS [22] and introduced the light-touch leasing process to make the spectrum use rights held by PALs available in secondary markets.…”

This paper discusses the regulatory and standardization status of the Licensed Shared Access (LSA), compares it with the US Citizens Broadband Radio Service concept, and reviews results from the ongoing feasibility study in the European Telecommunications Standards Institute on temporary spectrum access for local high-quality wireless networks. Based on comparative analysis, a new LSA evolution concept and functional architecture is proposed, and the early results of the world first LSAevo validation are presented. Introduced system architecture can be applied to 3.4-3.8 GHz band so that fragmentation challenges to take the band into 5G use in the European member states can be solved, while ensuring that the communication of the incumbent users, fixed wireless access, fixed links, and satellite earth stations do not experience any harmful interference. In the end-to-end field trial, local high-quality wireless network use case for an industrial automation Micro-operator is validated.

“…In this technique, same frequency is shared between uplink and downlink in different time slots [1]. Advanced LTE bands like LTE B 42 (TD 3500), LTE B 43 (TD 3700) and Citizens Broadband Radio Services (CBRS) band offer high speed broadband services and are key bands on which future technologies may be built upon [2]. In recent times, MIMO platforms have been worked upon to reduce their dimensions in order to incorporate more antenna terminals on a single platform.…”

Multiple Input Multiple Output antenna systems have been the key reasons behind tremendous increase in speed with which data can be transferred through air. The focus area with these antenna designs has been to obtain small size with good performance of the system. In this paper a MIMO antenna system is proposed that is made up of two PIFA elements. The system is capable of operating in advanced LTE In recent times, MIMO platforms have been worked upon to reduce their dimensions in order to incorporate more antenna terminals on a single platform. The problem with the reduced size of the MIMO systems is the increase in mutual coupling between antenna terminals [3]. This interaction between electromagnetic radiation of the antenna elements lead to degradation in the performance parameters of the MIMO system [4]. Many performance enhancement techniques to improve the performance of closely spaced MIMO antenna elements systems have been proposed. These techniques include the use of defected ground structures, impedance transformers, neutralization lines, parasitic components etc. These techniques try to divert the direction of the surface current flowing on the antenna surface to reduce electromagnetic interaction between antenna elements [5], [6]. The disadvantages of above mentioned techniques are their complex geometry and comparatively large design. Recently, a performance enhancement technique using metamaterial structures is being used in MIMO antenna systems to reduce the mutual interaction between elements and increase the overall performance of the system. Metamaterial are negative permeability material structures that offer imaginary propagation constant for surface electromagnetic waves and hence curtail them from propagating from one terminal to another. This results in a reduction in mutual coupling and an increase in the isolation [7]. This reduction in mutual coupling reflects on the performance of the MIMO system also with improved MIMO coefficients like TARC, ECC and Channel Capacity Loss. MIMO systems that exist in literature focus on wideband operations but there are hardly any systems which primarily focus upon advanced LTE bands. The wideband designs result in moderate performance of the systems in these particular bands. There are various MIMO antenna designs in literature which include [8], in which two element MIMO system for ultra-wide band (UWB) operation is proposed. The disadvantage of the system is its large size and poor TARC and ECC characteristics. In [9], a wide-band
