1 Scope
The present document defines system requirements for operation of mobile broadband service in the 2 300 - 2 400 MHz
band under Licensed Shared Access (LSA). This band is allocated to the Mobile Service and identified for IMT globally
in the ITU Radio Regulations. The objective of LSA is to enable access to this band for mobile/fixed communication
networks (MFCNs) in those CEPT countries where access to the band is complex due to Incumbent usage, as
documented in ETSI TR 103 113 [i.1] (for example, when it is not viable to "refarm" the band in a timely manner [i.2]).
An LSA system comprises one or more Incumbents, one or more MFCNs (LSA Licensees), and the means to enable
coordination between Incumbents and LSA Licensees, such that the latter may deploy their networks without harmful
interference. The requirements in the present document are intended as a first step towards the definition of LSA
System architecture specifications.

4.3 Requirement Formulation
A requirement is formulated in such a way that it is uniquely defined. It is built as follows:
Title: </br> Description: the description of a requirement will be formulated using one of the following terms:</br> • "shall" is used to express mandatory requirements (i.e. provisions that have to be followed)</br> • "should" is used to express recommendations (provisions that an implementation is expected to follow unless</br> there is a strong reason for not doing so)</br> • "may" is used to express permissible actions (provisions that an implementation is able to follow or not follow)</br> 4.3.1 LSA Roles</br> Requirements are formulated in regards of the "LSA System" and make use of generic "LSA roles", as shown in</br> Figure 4.2.</br> </br> Figure 4.2: LSA Roles</br> Roles are abstracted concepts defined for requirement formulation; in specific deployments, roles will be performed by</br> specific entities (e.g. the LSA Licensee role would be performed by a MFCN operator in the 2 300 - 2 400 MHz band).</br> In addition, multiple roles may be performed by the same entity (e.g. the Administration/NRA may perform also the</br> LSA System Administrator role).</br> Each of the roles may interact with the LSA System, and may also interact with each other via the LSA System.</br> There may be multiple instances of a given role in respect of a particular requirement.</br> 5 Working Assumptions</br> The working assumptions described below are based on ETSI TR 103 113 [i.1], and particularly the use case</br> "Bandwidth Expansion for Mobile Network Operator" in clause 7.1.2 of [i.1], as well as the ECC Report 205 [i.2] and</br> the RSPG opinion on LSA [i.3].</br> ETSI</br> </br> ---------------------- Page: 9 ----------------------</br> 10 ETSI TS 103 154 V1.1.1 (2014-10)</br> 5.1 Regulatory Background</br> It is assumed that, prior to implementation of LSA, the 2 300 - 2 400 MHz frequency band (or a sub-band) is used by</br> one or more non-IMT services, provided by current holder(s) of spectrum rights of use. LSA provides for some</br> administrations a solution to enable access to the 2 300 - 2 400 MHz frequency band for MFCN and impacts the</br> national allocation of a frequency band.</br> The Sharing Framework is the central piece for the implementation of LSA at national level. It will define for a given</br> frequency band the spectrum, with corresponding technical and operational conditions, that can be made available for</br> LSA. National administrations should decide which existing applications need to be considered as Incumbents within</br> the Sharing Framework and maintained in the long term according to national policy objectives, and taking into account</br> international obligations and community law in the case of EU Member States.</br> It is further assumed that one or more MFCN operators ("LSA Licensees") are subsequently granted individual rights to</br> use distinct portions of the Incumbent's spectrum resource (authorizations) [i.2]. Sharing rules should be part of the</br> corresponding licenses granted by the Administration/NRA, thus reinforcing the legal certainty to the parties, and in</br> particular to the Incumbents. The LSA Licensees are allowed to use the spectrum resource in accordance with such</br> rules included in their rights of use, thereby allowing all the authorized users, including Incumbents, to provide a certain</br> QoS [i.3].</br> The Sharing Framework [i.2] would be established under the responsibility of the Administration/NRA (following</br> consultations involving key stakeholders); the Administration/NRA is further expected to issue the individual</br> authorizations to LSA Licensees, and may have a role in monitoring spectrum use, and validating that such use is</br> compliant with the individual right of use, including the Sharing Framework.</br> 5.2 Spectrum Sharing Arrangement</br> The set of practical details for a given LSA spectrum resource is referred to in the present document as a Sharing</br> Arrangement. A Sharing Arrangement may be subject to change, but it should remain consistent with the Sharing</br> Framework defined by the Administration/NRA and the obligations placed in the "Authorization" Directive for</br> assigning spectrum resource for the delivery of Electronic Communication Services (ECS).</br> LSA spectrum resource sharing may in general be dynamic, i.e. the requirements of the Incumbent may be such that</br> some portions of the spectrum are not permanently available to the LSA Licensee in any given location. However, a</br> particular Spectrum Sharing Arrangement may include constraints on the potential variations of resource availability</br> (e.g. to facilitate implementation or operability). Examples of such constraints are given below, noting that a particular</br> Sharing Arrangement may include a combination of multiple constraints:</br> • Changes in the spectrum resource availability may only occur at pre-set times (e.g. periodic)</br> • There may be minimum allowed intervals between successive changes (in general or affecting a given area)</br> • Spectrum resource availability may be pre-configured (only a finite set of possible combinations in</br> space/frequency is allowed)</br> • Changes may not be allowed if they violate certain statistical criteria (e.g. overall availability of a certain</br> resource in a given time frame)</br> It is assumed that an LSA Licensee is granted individual rights of use by the relevant NRA. This implies that the LSA</br> System will provide means to guarantee coexistence between Incumbents and LSA Licensees in general, but there is no</br> special need to handle coexistence between LSA Licensees beyond normal deployment requirements (such as</br> deployment of adjacent band users in same area, or same-band users in adjacent areas).</br> It is assumed that Incumbents and LSA Licensees not involved in a particular Sharing Arrangement will not get access</br> permission to the respective LSA spectrum resource and will not receive information on the designated LSA spectrum</br> resource.</br> rd</br> 5.3 LSA System Administration by Trusted 3 Party Users</br> rd</br> It is assumed that the LSA System or part(s) thereof may be administered by trusted 3 party user(s) with defined</br> access rights.</br> ETSI</br> </br> ---------------------- Page: 10 ----------------------</br> 11 ETSI TS 103 154 V1.1.1 (2014-10)</br> 6 Functional System Requirements</br> 6.1 General System Operation</br> This clause comprises functional requirements that relate to the general system operation.</br> 6.1.1 R-FUNC-GEN-01 LSA Spectrum Resource Sharing</br> The LSA System shall support flexible spectrum resource sharing in the 2 300 - 2 400 MHz frequency band (or a</br> sub-band thereof) between the Incumbent(s), and a limited number of LSA Licensees (MFCNs), according to the</br> applicable LSA Sharing Framework.</br> Explanation: In general, spectrum assigned to Incumbent(s), may be used by MFCNs according to the applicable LSA</br> Sharing Framework. The LSA System will allow an LSA spectrum resource unused by the Incumbent (considering</br> time, space and frequency domains) to be made available in a flexible manner to the MFCN, on a non-interfering basis.</br> 6.1.2 R-FUNC-GEN-02 Quality of Service</br> The LSA System shall facilitate the provision of a predictable Quality of Service (QoS) for both Incumbents and LSA</br> Licensees, whenever operation by a particular service is allowed by the system.</br> Explanation: The LSA System supports sharing on a non-interfering basis, meaning that the sharing systems will</br> operate without causing harmful interference. Predictable QoS in this context means that a system can perform in a</br> similar way to a non-sharing case, at the radio level.</br> 6.1.3 R-FUNC-GEN-03 Information Exchange between Incumbent and</br> LSA Licensee</br> The LSA System shall provide means for the exchange of information between an Incumbent, and an LSA Licensee to</br> enable the LSA Licensee to be made aware of the LSA spectrum resource that is available for its use and its possible</br> changes over time.</br> Explanation: Legacy sharing arrangements are typically made in a static fashion (e.g. a secondary user may use a</br> certain portion of spectrum in a given area until told otherwise). In order for LSA spectrum resource sharing to occur in</br> an efficient manner, the LSA System will include efficient interfacing between Incumbent and LSA Licensee to enable</br> changes in the available LSA spectrum resource to be communicated to the Licensee.</br> 6.1.4 R-FUNC-GEN-04 Multiple MFCN Support</br> The LSA System shall allow the Incumbent to interact with one or more LSA Licensees for spectrum sharing purposes.</br> Explanation: A single Incumbent user may communicate with multiple MFCNs to provide information on the LSA</br> spectrum resource available to each. For example, an Incumbent may have usage rights for a 20 MHz band, and two</br> MFCNs are authorized to use 10 MHz each (non-overlapping bands) as LSA Licensees. The information sent to each</br> MFCN reflects the degree of Incumbent usage only, since the LSA System does not support contention between</br> MFCNs. Each LSA Licensee has an individual authorization to use a particular LSA spectrum resource, subject to a</br> suitable grant provided by the LSA System.</br> 6.1.5 R-FUNC-GEN-05 Multiple Incumbent User Support</br> The LSA System shall allow an MFCN to interact with one or more Incumbents for spectrum sharing purposes.</br> Explanation: A particular MFCN may be authorized as an LSA Licensee of different LSA spectrum resources, each</br> shared with a particular Incumbent. For example, it may have usage rights to two different sub-bands, each shared with</br> a particular Incumbent.</br> ETSI</br> </br> ---------------------- Page: 1</br> <b>...</b>
