34、ethodology This clause describes how the requirements are organized and the related format. 4.1 Requirement Organization As shown in Figure 1, the requirements described in the present document belong to two different categories: the functional requirements and the performance requirements. Each cat
35、egory, in turn, is organized into groups. ETSI ETSI TS 102 946 V1.1.1 (2014-07)9Figure 1: Overall requirements structure 4.2 Requirement Format A letter code system is defined which makes a unique identification of each requirement R-. It should be constructed as follows: R- : Standard requirement p
36、refix - Code Category FUNC Functional aspects PERF Performance aspects GROUP: Requirement group identifier. A letter code will be used for this identifier. The three first letters will give the identifier of the group. 4.3 Requirement Formulation A requirement is formulated in such a way that it is
37、uniquely defined. It is built as follows: Title: Description: the description of a requirement will be formulated using one of the following terms: - “shall“ is used to express mandatory requirements (i.e. provisions that have to be followed); - “should“ is used to express recommendations (provision
38、s that an implementation is expected to follow unless there is a strong reason for not doing so); - “May“ is used to express permissible actions (provisions that an implementation is able to follow or not follow. ETSI ETSI TS 102 946 V1.1.1 (2014-07)105 Working assumptions There are two approaches f
39、or use of TVWS channels by each CRS, uncoordinated approach and coordinated approach: Uncoordinated use of TV White Space implies that each CRS independently uses available TV White Space resources obtained with the help of geo-location database without any help from a spectrum coordination function
40、 to coordinate spectrum usage with its neighbour CRSs. Coordinated use of TV White Space implies that each CRS uses available TV White Space resources obtained with the help of geo-location database and with additional knowledge of spectrum usage by its neighbour CRSs and/or decision making from a s
41、pectrum coordination function. The tag “COOR“ in the requirement identifier indicates that the requirement applies only to the coordinated use and any requirement without the “COOR“ tag applies either to the uncoordinated use or to the coordinated use. 6 Metrics The present document derives the requ
42、irements from the use cases and technical challenges as defined in TR 102 907 i.1. It requires the availability of metrics related to the operational state of the network (or parts of it) and the user requirements. This clause describes these metrics on which the requirements are based. 6.1 Quality
43、of Service (QoS) QoE requirements for EPG; QoE requirements for browser; QoE requirements for content navigation. 7 System Requirements 7.1 Terrestrial Broadcasting Service Protection Requirements 7.1.1 Requirements for advanced geo-location function The system may support advanced geo-location func
44、tion to facilitate management for Terrestrial Broadcasting Service protection. The function employs the calculation function of location specific WSD output power level for Terrestrial Broadcasting service receiver protection. This clause defines the requirements for the advanced geo-location functi
45、on. Explanation: There will be several possible deployment scenarios for the calculation function of location specific WSD output power level. For example, the calculation function may be a part of the geo-location database controlled by a regulatory body, or a separate function (namely advanced geo
46、-location function) from the geo-location database managed by regulatory body. In the former case, any requirements definition on this function will be unnecessary, because it will be defined in each regulatory body itself. On the other hand, in a case where it is a separate function, a third party
47、should take a responsibility to protect the Terrestrial Broadcasting service receivers, and the operation should be kept under surveillance by a regulatory body. In this case, requirements will be necessary in defining the interface between WSD and this calculation function. 7.1.1.1 R-FUNC-TER-01 Lo
48、cation specific WSD output power level calculation function If the system supports an advanced geo-location function, the advanced geo-location function shall support calculation of location specific WSD output power level which takes into consideration the number of active master WSDs in operationa
49、l TVWS channels in order to satisfy Terrestrial Broadcasting service protection requirements. ETSI ETSI TS 102 946 V1.1.1 (2014-07)12Explanation: The location specific output power level calculation for a newly entering WSD should be based on relevant parameters of both the newly entering WSD and other active master WSDs. In addition, the advanced geo-location function should re-calculate the location specific output power levels of the active master WSDs. The re-calculated maximum power levels are sent from the advanced geo-location fu
