Scope and Field of Application |
The work item will develop a System Reference Document (SRDoc) for mobile broadband services in the 2300 MHz – 2400 MHz band under Licensed Shared Access (LSA) regime. The objective of the work item is to enable access to this band for mobile broadband services in those CEPT countries where access to the band is complex due to the incumbent uses. LSA when used by IMT/mobile broadband is similar to the Authorized Shared Access (ASA) . The SRDoc will outline • expected usage scenarios • technical characteristics and parameters necessary to describe the spectrum needs and performance requirements for the deployment of mobile broadband services under LSA regime while meeting the constraints of mutual coexistence between mobile broadband services and incumbent users based on already existing/further CEPT spectrum sharing and compatibility studies • high level functions required to manage/comply with the requirements for the deployment of mobile broadband services under LSA regime. [Background] The 2300 MHz – 2400 MHz frequency band is allocated to the Mobile Service and identified for IMT globally in the ITU Radio Regulations. It is targeted for use by TDD technology (e.g. 3GPP LTE Band 40). In a number of CEPT countries, the access to this band for mobile broadband will be possible, however in a number of other CEPT countries, the access to this band will be complex and lengthy due to the incumbent uses such as wireless cameras and video links (ENG-links), public safety, amateur services, aeronautical telemetry, governmental use (incl. military) and fixed links. The aim is to contribute to the availability of the frequency band 2300 – 2400 MHz for mobile broadband within CEPT, on a timely manner and under harmonised technical conditions, while taking into account the various incumbent uses in a number of CEPT countries. LSA is a new complementary regulatory framework to enable access to spectrum through sharing between incumbents and a limited number of “LSA licensees” (e.g. mobile network operators). Alongside the use of spectrum by the incumbent, further “LSA licensees” can be authorised by the regulators and granted rights to use the radio frequencies. It is a right to utilise those parts of spectrum in spatial or time domain that are unused by the incumbent, upon agreed terms and conditions defined with the incumbent. The agreed conditions may be “static” (e.g. static exclusion zone, static time allowed for operation) or more ‘dynamic’ (e.g. geographic/time sharing, on-demand authorisation of operators licensed under LSA or on-demand restrictions by incumbents). As such, a system for updating, maintaining and providing the access conditions is to be established. A key feature of LSA is to ensure a predictable. quality of service for all spectrum use rights holders, network operators and for consumers. The harmonisation and use of the 2300 MHz – 2400 MHz band for mobile broadband across CEPT will benefit from LSA implementation due to the variety and foreseen long term usage of incumbents in a number of countries. The implementation of LSA by CEPT countries would be on a voluntary basis. Some CEPT countries have already plans to release the 2.3 GHz, others are having difficulties to make such release on a timely basis and could apply the LSA framework to cope with this situation. This will allow CEPT to reap the full benefits of the large of economies of scale in TDD equipment. (1) CEPT WG FM, at its 74th Meeting in April 2012, agreed that the following tasks should be handled on the LSA concept : - Study the “level of guarantee” in terms of spectrum access that is required by an operator to invest in the deployment of a network (or at least in the upgrade of its existing network). This notion will, on the other hand, affect the “level of guarantee” that the incumbent can ensure to the LSA licensee. - When identified as a framework relevant for a given frequency band, develop the harmonisation framework (ECC Decision, recommendation) with reference to the relevant LSA framework. - Develop general conditions and band-specific technical/operational conditions for the implementation of the LSA concept that could be used as guidelines for CEPT administrations. These guidelines could be published as an ECC Report. Establish relevant interaction with ETSI in order to translate relevant sharing requirements in harmonised standards including those in relation with the implementation of the LSA framework. CEPT WG FM also concluded regarding the 2300-2400 MHz band that: - Harmonisation work should be undertaken for the implementation of broadband MFCN in the band; - Incumbent use of the 2.3-2.4 GHz band should be ensured through appropriate regulatory framework. In that respect, using the LSA concept should be considered. |
