1 Scope
The present document defines the application protocol on the LSA interface, between LSA Controller (LC) and LSA
1
Repository (LR) [i.2] (LSA protocol), and the content of the LSA Spectrum Resource Availability Information
1
(LSRAI) conveyed by this protocol. It is based on the System Requirements defined in ETSI TS 103 154 [i.1] and the
System Architecture and High Level Procedures defined in ETSI TS 103 235 [i.2].
The present document supports the operation of mobile broadband service in the 2 300 MHz - 2 400 MHz band under
Licensed Shared Access (LSA), aimed at enabling access for mobile/fixed communication networks (MFCNs) in those
CEPT countries where access to the band is foreseen but cannot be provided without restrictions due to Incumbent
usage, as documented in ETSI TR 103 113 [i.3]. Application to other bands is not precluded and depends on future
regulatory decisions.

3.1 Definitions
For the purposes of the present document, the following terms and definitions apply:
idle zone: zone which has been defined but which is not currently operational
LSA Licensee: entity operating a MFCN, which holds individual rights of use to an LSA spectrum resource
LSA spectrum resource: spectrum resource which is to be shared between an Incumbent and a LSA Licensee on a

4 LSA Spectrum Resource Availability Information:
Description and Supported Functionality on LSA
1
4.1 Introduction
Clause 4 contains a high level description of the LSA Spectrum Resource Availability Information (LSRAI), and
LSRAI-related functionality supported by the nodes (LC and LR), and the interface (LSA ). This clause expands the
1
related material in the stage 2 specification of ETSI TS 103 235 [i.2], and describes detailed requirements for the LSA
1
protocol and its operation.
4.2 LSRAI Scope
LSA Spectrum Resource Availability Information (LSRAI) is information provided to a LSA Licensee, which conveys
information on the LSA spectrum resource that may be used by the LSA Licensee. As described in ETSI
TS 103 235 [i.2], LSRAI is generated in the LR, and sent to the LC over the LSA1 interface, using LSA protocol
1
messages.
Under LSA operation ECC Report 205 [i.4], it is assumed that the terms of a license will contain a description of the
spectrum resource which is allocated to the respective LSA Licensee, and therefore such information is not required to
be conveyed over LSA as part of LSRAI. LSRAI therefore includes any additional operational conditions or
1
restrictions that the Licensee shall apply, and which may be subject to change.
NOTE: It is a deployment choice whether permanent restrictions contained in the sharing framework or sharing
arrangement, ETSI TS 103 154 [i.1], are conveyed to the LC as part of LSRAI.
The conditions or restrictions within LSRAI may apply to the licensed spectrum resource, or to a subset (described in
frequency, space, time or a combination of these).
4.3 LSRAI Definition
LSRAI has the following characteristics:
• It contains one or more Zones. A Zone is an information object which describes a set of operational conditions
or restrictions to be applied by the LSA Licensee.
• A Zone has a Zone Type associated to it (e.g. restriction, protection, exclusion).
• A Zone contains space, frequency, radio and time parameters:
- Space parameters describing the geographical area to which the restriction applies.
- Frequency parameters describing the frequency range to which the restriction applies.
- Time parameters describing when the restriction applies.
- Radio parameters describing the RF restrictions to be applied within the space/frequency/time
combination defined by the above parameters.
• A Zone has a Zone ID and a Zone Configuration Index associated to it.
NOTE: When LSRAI is conveyed over the LSA interface, each Zone is associated to a Zone Action.
