“…ECC Reports 15(04) and 172 [4,5] describe the scenarios and technical requirements for the sharing of this frequency band between PMSE users and possible mobile broadband users. Several studies and trials have been conducted on spectrum sharing using Licensed Shared Access (LSA) and coexistence between PMSE and LTE systems [6,7,8]. ECC Recommendation 15(01) considers cross-border coordination of 4G and 5G Mobile/Fixed Communications Networks (MFCN) to avoid harmful interference and provides guidance in case of synchronized and unsynchronized MFCN TDD systems operation [9].…”

Private wireless networks have recently gained interest in many business applications. Use of 4G and 5G technologies for private network deployments has become feasible recently. Finnish Transport and Communications Agency Traficom began to grant licenses for private mobile Time Division Duplex (TDD) networks on frequency band 2300-2320 MHz in 2020. In this study, the coexistence of two 4G TDD networks is investigated through an extensive measurement campaign. The laboratory test setup developed to conduct the interference measurement campaign can be used to study 4G and 5G TDD technologies in frequency bands below 4 GHz. Networks using TDD technology are recommended to use synchronized frame configurations to avoid interference. Private network applications and requirements differ between user organisations and hence the uplink and downlink data rate requirements are different and may need different TDD frame configurations. This paper studies interference between adjacent private networks, which have same or different TDD frame configurations. Measurement results indicate that non-synchronized networks produce interference and significant decrease in data throughput in neighboring networks.

Use of 4G and 5G technologies for local industrial networks has become feasible in recent years. This paper studies the co-existence of two geographically limited adjacent Time Division Duplex (TDD) local networks through a field measurement campaign. The networks have the same or different TDD frame configurations. The test setup developed to conduct the interference measurement campaign can be used to study both 4G and 5G TDD technologies. Measurement results indicate that non-synchronized networks produce interference and significant decrease in data throughput in neighboring networks. Thus, networks using TDD technology are recommended to use synchronized frame configurations to avoid interference. However, local network applications and their requirements may differ between user organizations, and hence the uplink and downlink data rate requirements are different and may need different TDD frame configurations.

“…Let us mention that the authorized shared access (ASA) concept also falls under the LSA umbrella [8], [9]. LSA evolution is also being developed to provide user priorities and more dynamic overall approach to access shared spectrum resources [10], [11].…”

Since the introduction of the idea of cognitive radio, various approaches towards spectrum sharing have been considered, for example, the Licensed Shared Access (LSA), which is considered in Europe, or Citizens Broadband Radio Service (CBRS) with Spectrum Access System (SAS) regulated by the US. This paper deals with the problem of coordinated resource allocation among a set of available base stations. A detailed definition of the problem is provided, followed by a discussion on a set of heuristics proposed for solving the problem. Four solutions are presented that are based on existing standards as well as on the approaches described in the literature. Next, new multi-selection (multi-choice) algorithm is proposed and discussed in detail. The main problem is divided in two subproblems, which are solved by using graph theorem and analytical description. The performance of the proposed solutions is analyzed in various scenarios. Finally, a trade-off between power allocation and frequency use is provided. All challenges identified during the investigation of the problem are presented.
