Introduction
The concept of local high-quality wireless networks has been identified in ETSI TR 103 588 [i.1] as a collective term to
enclose a kind of use cases targeting local area services requiring predictable levels of QoS, e.g. in vertical industrial
sectors such as industrial automation, PMSE, PPDR and e-Health. Their need for predictable levels of QoS mostly
preclude operation in a license-exempt spectrum, due to coexistence issues, and target exclusively licensed spectrum.
However, due to the current scarcity of suitable exclusive licensed spectrum resources, which can be directly accessible
by vertical local area service providers, spectrum sharing has been proposed in [i.1] as the enabling spectrum
technology for introducing QoS enabled local area services in licensed bands.
NOTE: In the present document, the term "local area service provider" used in [i.1] is substituted by the term
"MFCN operator". An MFCN operator refers to e.g. a vertical sector operator.
ETSI
---------------------- Page: 5 ----------------------
6 ETSI TS 103 652-1 V1.1.1 (2019-02)
Three possible spectrum sharing schemes have been identified in [i.1] for providing local area services focusing on QoS
in licensed bands:
1) MNOs can offer dedicated local area services in their licensed frequencies.
2) MNOs can lease part out of their spectrum locally to local area service providers.
3) Spectrum can be nationally licensed to local area services providers.
Scheme 1 addresses the hosting of local high-quality wireless networks as service network areas by MNOs. Schemes 2
and 3 target the deployment of local high-quality wireless networks as standalone private networks.
The use of scheme 2 is not limited to MNO bands, but any licensed band can be used where leasing is regulatory
allowed.
All three spectrum sharing schemes aim to facilitate licensed spectrum sharing between local vertical sector operators,
with specified geographical and temporal limits, and incumbents both in IMT and non-IMT bands. In this context, the
focus on IMT-bands facilitates wide availability of equipment since those bands are also used by Mobile Network
Operators (MNOs).
For enabling each of the three functional use cases, clauses 6.1 and 6.2 in [i.1] provide examples of functional
architectures in a general sense and within the current LSA framework [i.2], [i.3] and [i.4], respectively.
The main advantage of embracing the LSA framework is that it aims to ensure a predictable level of QoS at a defined
location for all spectrum resource users, i.e. LSA licensees and incumbents. The current LSA framework was designed
to share spectrum resources between Incumbents and LSA Licensees acting as MNOs. However, the support of vertical
local area service providers as a new type of LSA licensees, which asks for both shorter or longer time of spectrum
resource deployments with a predictable QoS level, and the expected higher number of these new type of LSA licensees
make it necessary to evolve the current LSA framework on both system and CEPT/NRA levels.
At the regulatory level, for instance, the role concept in LSA needs to be evolved opening the LSA method to include
local vertical sector operators as licensees.
At LSA system level, Table 6 in ETSI TR 103 588 [i.1] lists an overview of identified potential functional
enhancements to the current LSA system and the corresponding affected LSA entities.
The present document leverages on the findings in ETSI TR 103 588 [i.1] to technically specify the requirements for
providing spectrum access for local high-quality wireless networks within the LSA framework [i.5].

1 Scope
The objective of evolving the LSA framework towards an eLSA (evolved LSA) system is to support spectrum access to
local high-quality wireless networks operated by vertical sector operators, as introduced in ETSI TR 103 588 [i.1]. The
present document specifies system requirements for that purpose.
ETSI TC RRS work on eLSA is of technical nature aiming to provide an automatic tool to facilitate spectrum sharing
coordination between incumbents, NRAs and eLSA Licensees (e.g. vertical sector operators).
To meet the spectrum access demand and needs of local high-quality wireless networks, eLSA aims to offer technical
means to facilitate the spectrum allocation procedure, including automatic local area licensing and leasing agreements,
and to manage the conditions of spectrum use. The work is based on the generic aspects of the current ETSI
specifications [i.2], [i.3] and [i.4] for Licensed Shared Access (LSA) in the 2 300 - 2 400 MHz band and on the
functional enhancements proposed in ETSI TR 103 588 [i.1].
The work targets operation of local high-quality wireless networks in licensed bands to guarantee predictable QoS
levels. It is agnostic to the radio frequency bands.
The work on eLSA is based on the LSA concept [i.5], i.e. same architecture, role assumptions and applicable
functionality.
The requirements in the present document are intended to be used for the definition of an evolved LSA system
architecture specification for providing spectrum access for local high-quality wireless networks.

3 Definition of terms, symbols and abbreviations
3.1 Terms
For the purposes of the present document, the following terms apply:
allowance zone: geographical area within which an eLSA Licensee is allowed to operate radio transmitters on its
assigned spectrum resource
NOTE 1: An allowance zone is defined using specific measurement quantities and thresholds, e.g. a maximum field
strength level expressed in dBµ V/m/MHz, along the border of its geographical area.
NOTE 2: An allowance zone is normally applicable for a defined frequency range and time period.
eLSA licensee: entity operating a MFCN, which holds individual rights of use to an eLSA spectrum resource
NOTE: eLSA licensee role extends the scope of LSA licensees to include vertical sectors stakeholders
(e.g. vertical local area communication service providers/operators).
eLSA spectrum resource: spectrum resource which is to be shared between an incumbent and an eLSA licensee on a
static or dynamic basis according to the sharing framework defined by the administrations (NRAs)
eLSA system: system that enables and/or facilitates the realization of eLSA, and which comprises the eLSA specific
technical features, architecture, protocols, and interfaces
incumbent: current holder of spectrum rights of use
lease: arrangement between the lessor and the lessee for using parts of the spectrum, a particular geographical area, or a
combination of both, over a period of time
lessee: entity which holds right of use to a certain spectrum resource from a lessor under a lease
lessor: entity holding individual rights of use (license) to a certain spectrum resource, which leases out parts of his
license to a lessee under a lease
protection zone: geographical area within which incumbent receivers will not be subject to harmful interference caused
by eLSA/LSA licensees' transmissions
NOTE: A protection zone is defined using specific measurement quantities and thresholds (e.g. a mean field
strength that does not exceed a defined value in dBµ V/m/MHz at a defined receiver antenna height above
ground level). A protection zone is normally applicable for a defined frequency range and time period.
restriction zone: geographical area within an allowance zone where an eLSA Licensee has to operate under certain
additional restrictive conditions (e.g. maximum EIRP limits and/or constraints on antenna parameters)
sharing arrangement: set of practical details for sharing an eLSA and/or LSA spectrum resource
ETSI
---------------------- Page: 8 ----------------------
9 ETSI TS 103 652-1 V1.1.1 (2019-02)
sharing framework: set of sharing rules or sharing conditions that will materialize the change, if any, in the spectrum
rights of the incumbent(s) and define the spectrum, with corresponding technical and operational conditions, that can be
made available for alternative usage under eLSA and/or LSA
spectrum resource: resource or set of resources defined in time, space and frequency domains
vertical sector operator: operator of a local high-quality wireless network (MFCN) addressing a vertical sector
specific local connectivity needs
NOTE: The concept of "vertical sector" is used to name business sectors that have a need to use MFCNs to
maintain their operations, such as the transport, the culture and creative, the industrial automation or the
healthcare sectors. Different vertical sectors have different connectivity requirements: e.g. capacity,
network quality, latency, communication security and reliability.
