STANDARDIZATION OF LICENSED SHARED ACCESS

LSA  definition by RSPG 
“A regulatory approach aiming to facilitate the introduction of radiocommunication systems operated by a limited number of licensees under an individual licensing regime in a frequency band already assigned or expected to be assigned to one or more incumbent users.
Under the Licensed Shared Access (LSA) approach, the additional users are authorised to use the spectrum (or part of the spectrum) in accordance
with sharing rules included in their rights of use of spectrum, thereby allowing all the authorised users, including incumbents, to provide a certain Quality of Service (QoS)”

Active Working Groups

ETSI Reconfigurable Radio systems (RRS) WG1 – System Aspects (link)

ETSI RRS TR 103 113 “System requirements for operation of Mobile Broadband Systems in the 2300 MHz- 2400 MHz band under Licensed Shared Access (LSA) regime”

Scope of work to be undertaken: This Technical Specification defines system requirements for operation of Mobile Broadband Systems in the 2300 – 2400 MHz frequency band under Licensed Shared Access regime. The Technical Specification will serve as an input for defining the Harmonized Standards and European Standards that are part of the EC mandate for Reconfigurable Radio Systems (M/512). Therefore, this work is performed in a close liaison with the Joint Task Force ERM RRS (JTFER) related to EC Mandate M/512 and where applicable, additional requirements will also be provided by JTFER.

ETSI RRS TS 103 154 “System Reference Document; Mobile broadband services in the 2300 MHz – 2400 MHz frequency band under Licensed Shared Access regime”

Scope of work to be undertaken: This specification provided by this work item describes mobile broadband service in the 2300 – 2400 MHz band under Licensed Shared Access (LSA) regime. This band is allocated to the mobile service and identified for IMT globally in the ITU Radio Regulations. The objective of the LSA regime 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. The LSA regime may require changes in the present regulatory framework for mobile applications regarding either intended or unwanted emissions. 

ETSI RRS TS 103 235 "System Architecture and High Level Procedures for operation of Licensed Shared Access (LSA) in the 2300 MHz-2400 MHz band" 

Scope of work to be undertaken: This Technical Specification defines the system architecture for the operation of Licensed Shared Access, enabling operation of Mobile Broadband Systems under Licensed Shared Access regime. The architecture builds on the scenarios and applications described in ETSI TR 103 113 "Mobile Broadband Services in the 2 300 MHz - 2 400 MHz Frequency Band under Licensed Shared Access Regime", and the system requirements captured in ETSI TS 103 154 "System requirements for operation of Mobile Broadband Systems in the 2 300 MHz - 2 400 MHz band under Licensed Shared Access (LSA) regime. The scope of the work will be to define the architecture of a system which enables LSA following the requirements developed in TS 103 154 . The Technical Specification will serve as an input for defining the Harmonized Standards and European Standards that are part of the EC mandate for Reconfigurable Radio Systems (M/512).
