Radio applications provide their resource needs (e.g. using operational states) so that the multiradio computer may judge whether these resources are available, in orde

33、how the requirements are organised and the format of the requirement. 4.1 Requirement Organization The present document is structured such that a level 1 section is dedicated to the requirements associated with a single category. The requirements should be partitioned into groups of related category
34、 to assist understanding. The overall structure is shown in figure 4.1.1. ETSI ETSI TS 102 969 V1.1.1 (2012-03)8Figure 4.1.1: Overall requirememts 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
35、follows: R-: Standard requirement prefix Code Category FUNC Functional aspects : Requirement group identifier. A letter code will be used for this identifier. The three first letters will give the identifier of the group. : Requirement identifier within requirement group; range 01 = 99. EXAMPLE: R-F
36、UNC-QOS-01 4.3 Requirement Formulation A requirement formulation is defined which makes a unique way to formulate it. It will be built as follows: Title: Description: The description of the requirement shall be formulated using one of the following terms. As described into the ETSI Terms resource al
37、location mechanism within separate application is not specified. ETSI ETSI TS 102 969 V1.1.1 (2012-03)103) MDRC-2: Radio applications use pre-defined static resources MDRC-2 implements multiple radio applications but no dynamic resource management is available. The radio applications for MDRC-2 come
38、 from a single radio application package which is normally provided by a MD vendor or SDR chipset manufacturer. In this scenario, we assume that software radio components in the radio application package are provided in platform-specific executable code. The rule for resource allocation for multiple
39、 applicationsg3A1, A2, , ANg3can be formulated as follows: Aig3450 Ri, ig35471, ., N, where Ridenotes resource allocated for application Ai, if i j so that Ri Rj then such applications cannot be run concurrently, all other combinations are allowed; resource allocation mechanism within separate appli
40、cation is not specified. 4) MDRC-3: Radio applications have static resource requirements For MDRC-3, a resource budget is defined for each radio application. This budget contains a static resource measure that represents the worst-case resource usage of the application, generated at radio applicatio
41、n compile-time. If an application is being started, the resource manager installed in MD of MDRC-3 checks its resource budget and the sum of all resource budgets of already running applications, and admits the new application only if the resources can still be guaranteed for all running applications
42、. In this scenario, we assume that software radio components in the radio application package are provided in platform-specific executable code. The rule for resource allocation for multiple applicationsg3A1, A2, , ANg3can be formulated as follows: Ai R(Ai), where R denotes total resources to be sha
43、red and R(Ai) denotes a part of R allocated for Ai; if for i1, i2, ., iM g35471, ., N, M N, R(Ai1) R(Ai2) . R(AiM) R then applications Ai1, Ai2, , AiMcan be run concurrently; resource allocation mechanism within separate application is not specified. 5) MDRC-4: Radio applications have dynamic resour
44、ce requirements This scenario assumes a similar resource manager in MD as for MDRC-3, but in addition the radio applications have now varying resource demands based on their current type of activity. Applications have separate operational states for different types of activity, and a resource budget
45、 is assigned to each operational state. In this scenario, we assume that software radio components in the radio application package are provided in platform-specific executable code. Resource management for MDRC-4 can be formulated as follows. Multiple applicationsg3A1, A2, , ANg3can be run and each
46、 applicationg3Aig3is divided into tasks t1(Ai), t2(Ai), ., tk(Ai). Resource allocation is provided by the resource manager in MD for each task tj(Ai) R(tj(Ai). The rule for task running is exactly the same as for MDRC-3 except that each application should be replaced by corresponding task. Therefore
47、, if for i1, i2, ., iM g35471, ., N, M N, R(tj1(Ai1) R(tj2(Ai2) . R(tjL(AiM) R then tasks tj1(Ai1), tj2(Ai2), ., tjL(AiM) can be run concurrently; resource allocation mechanism within separate task is not specified. 6) MDRC-5: Radio applications use pre-defined static resources, on-device compilatio
48、n of Software Radio Components This class corresponds to MDRC-2 with the difference that all or part of the software radio components are provided in the radio application package as platform-independent source code or platform-independent Intermediate Representation (IR), which is compiled on the M
49、D itself. It particularly means that MD should include a proper compiler in order to convert the source code or IR of the software radio components into an executable code that runs on a given modem chip of MD. It is assumed that the methods of radio programming and the tools to support this category have become sufficiently standardized so that third-party vendors may create radio applications and activate them to different platforms with relative ease.
