ETSI ETSI EN 303 145 V1.2.1 (2015-11) 7 1 Scope The present document defines the system architecture for the use of spectrum by White Space Devices (WSDs), specifically in the UHF TV Bands. The architecture stems from ETSI TS 102 946 1. The scope of the present document is to de
37、fine the architecture of a system which can allow operation of WSDs based on information obtained from Geo-location databases. The architecture will consider both uncoordinated use of White Space (where there is no attempt to manage the usage of channels by different WSDs) as well as coordinated use
38、 of White Space (where some form of channel management and/or coexistence techniques are employed to efficiently use the White Space). 2 References 2.1 Normative references References are either specific (identified by date of publication and/or edition number or version number) or non-specific.

Each entity is defined by its functional roles and re
47、ference points with other entities. The cognitive radio system (CRS) represents a white spaces device (WSD) or network of WSDs (i.e. a master WSD and some slave WSDs). The CRS uses available white space resources obtained with the help of geo-location database (GLDB) and/or with additional knowledge
48、 of spectrum usage by its neighbour CRSs provided by the spectrum coordinator (SC). The GLDB provides a WSD in a CRS with location specific information on the available frequencies and associated maximum EIRP values that the WSD is permitted to use. This will allow for protection of the incumbent se
49、rvice and is derived from information provided by the WSD and the minimum required Adjacent Channel Leakage Ratio (ACLR) of the WSD itself. ETSI ETSI EN 303 145 V1.2.1 (2015-11) 10 The SC is responsible for coordinating spectrum usage of CRSs based on the information obtained from GLDB as well as additional spectrum usage data from different CRSs using its service. Different SCs are capable of communicating with each other. The reference point A that is related to the uncoordinated usage of White Spaces is described in ETSI EN 301 598 i.5. 4.2 Coordinat
