35、 ETSI ETSI TS 103 145 V1.1.1 (2015-01)71 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 define the architecture

36、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 of White Space (where

37、 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 reference points with

46、 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 of spectrum usage

47、by its neighbour CRSs provided by the spectrum coordinator (SC). ETSI ETSI TS 103 145 V1.1.1 (2015-01)10The 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

48、 of the incumbent service and is derived from information provided by the WSD and the minimum required Adjacent Channel Leakage Ratio (ACLR) of the WSD itself. The SC is responsible for coordinating spectrum usage of CRSs based on the information obtained from GLDB as well as additional spectrum usa

49、ge data from different CRSs using its service. Different SCs are capable of communicating with each other. 4.2 Coordinated Usage of White Spaces 4.2.1 Spectrum coordination 4.2.1.1 Overview Spectrum coordination is the mechanism with which an SC serves CRSs so that they can operate efficiently in available spectrum resources of white spaces. The SC coordinates how to manage radio resources among a set of CRSs that are potentially interfering with each other (coexistence) and allows for channel assignment requested by a CRS that wishes to operate alone on a
