Reconfigurable Radio Systems (RRS); evolved Licensed Shared Access (eLSA); Part 1: System requirements
|Publication Date:||1 February 2019|
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.
