It has to be noted that each Use Case does not necessarily require fulfilling all the system requirements but only the ones related to the specific S
40、cenarios. Furthermore the requirements related to MD has to be intended as a means to fully benefit from the depicted RRS operations in which even non-reconfigurable multi-mode MDs can be fully supported. 6 Functional Requirements 6.1 Radio and Hardware Processing Resources Reconfiguration Requireme
41、nts 6.1.1 R-FUNC-RHR-01: Reconfiguration for each RAT The system shall support the reconfiguration of both the Hardware Processing Resources (HPRs) and the Radio Resources (RRs) for each supported RAT. Explanation: The system should be able to perform resource reconfiguration of both the hardware pr
42、ocessing resources and the radio resources for each supported RAT. The radio resources assigned to each supported RAT can be dynamically modified, which includes bandwidth, frequencies, power levels, spectrum masks, etc. Meanwhile, the percentage of hardware processing resources devoted to each supp
43、orted RAT should be dynamically modified. For example, sufficient HPR should be configured to a RAT when a new channel is assigned to it. NOTE: HPR indicates the hardware of the reconfigurable node (e.g. constituted by DSPs and FPGAs) that is used to run the software that implements the specific RAT
44、s functionalities (e.g. Base Band operations). The RF part is supposed to be separate and managed by specific modules (e.g. Radio Units (RUs) able to support more RATs at the same time with sufficient power capacity in order to respect the RF requirements of any single RAT i.1. 6.1.2 R-FUNC-RHR-02:
45、Reconfiguration between RATs The system shall support reconfiguration of both HPRs and RRs between different RATs. Explanation: The system can re-configure multiple RATs with flexibility in terms of the percentage of HPRs and RRs between different RATs according to the status of the network. 6.2 Req
46、uirements for functions supporting reconfiguration 6.2.1 R-FUNC-REC-01: Gathering and processing function The system shall support a gathering and processing function to gather and process certain radio related metrics and parameters. Explanation: After having gathered radio related metrics and para
47、meters, the gathering and processing function may process them to make decisions on reconfiguration in order to optimize radio performance. The identification of the radio related metrics and parameters which can be used for reconfiguration purposes may vary according the specific use case. These ar
48、e expected to include traffic variations, channel bandwidth, interference, transmit power, QoS, etc. 6.2.2 R-FUNC-REC-02: Support of trigger events for reconfiguration The system shall support trigger events for reconfiguration. Explanation: Trigger events are described by certain parameters (e.g. t
49、hresholds, hysteresis, etc.) in order to define the condition under which an event is happening. When one or more events occur, the system starts to evaluate the need for a possible reconfiguration. ETSI ETSI TS 102 968 V1.1.1 (2016-11)9 6.2.3 R-FUNC-REC-03: Support for reconfiguration function The system shall support a reconfiguration function to make decisions for radio resource reconfiguration and inform RBSs to perform the reconfiguration e.g. triggered by events in clause 6.2.2. Explanation: The reconfiguration function shall make
