Foreword This Technical Report (TR) has been produced by ETSI Technical Committee Reconfigurable Radio Systems
18、(RRS). Introduction The present document provides a feasibility study on defining and developing the concept of Cognitive Pilot Channel (CPC) for reconfigurable radio systems to support and facilitate end-to-end connectivity in a heterogeneous radio access environment where the available technologie
19、s are used in a flexible and dynamic manner in their spectrum allocation context. As a feasibility study the presented document provides basis for decision making at ETSI Board level on standardization of some or all topics of the CPC. ETSI ETSI TR 102 683 V1.1.1 (2009-09) 61 Scope The current trend
20、 for radiocommunications systems indicates a composite radio environment, where multiple Radio Access Technologies (RATs) links may be available at the same time. In this context, the cognitive capability of the terminals becomes increasingly a crucial point to enable optimization of the radio usage
21、. In order to obtain knowledge of its radio environment, a cognitive radio device may sense parts of the spectrum, which is necessary for its intention. This task may result in a very time and power consuming operation, if the parts of the spectrum to be sensed are large. In this context, the Cognit
22、ive Pilot Channel (CPC) solution could lead to a more efficient approach by conveying elements of the necessary information to let the terminal obtain knowledge of e.g. the available frequency bands, RATs, services, network policies, etc., through a kind of common pilot channel Therefore, the presen
23、t document aims at providing a study of the main concepts and possible implementations for the CPC in order to improve the spectrum and radio resources utilization in Reconfigurable Radio Systems. 2 References References are either specific (identified by date of publication and/or edition number or
