The justification of the study item was, that with enhancements such as HSDPA and Enhanced Uplink, the 3GPP radio-access technolog

43、y will be highly competitive for several years. However, to ensure competitiveness in an even longer time frame, i.e. for the next 10 years and beyond, a long-term evolution of the 3GPP radio-access technology needs to be considered. Important parts of such a long-term evolution include reduced late

44、ncy, higher user data rates, improved system capacity and coverage, and reduced cost for the operator. In order to achieve this, an evolution of the radio interface as well as the radio network architecture should be considered. Considering a desire for even higher data rates and also taking into ac

45、count future additional 3G spectrum allocations the long-term 3GPP evolution should include an evolution towards support for wider transmission bandwidth than 5 MHz. At the same time, support for transmission bandwidths of 5MHz and less than 5MHz should be investigated in order to allow for more fle

46、xibility in whichever frequency bands the system may be deployed ETSI ETSI TR 125 912 V14.0.0 (2017-04)113GPP TR 25.912 version 14.0.0 Release 145 Deployment scenario A very large set of scenarios are foreseen, as stated in 25.913 4: - Standalone deployment scenario: In this scenario the operator is

47、 deploying E-UTRAN either with no previous network deployed in the area or it could be deployed in areas where there is existing UTRAN/GERAN coverage but for any reason there is no requirement for interworking with UTRAN/GERAN (e.g. standalone wireless broadband application). - Integrating with exis

48、ting UTRAN and/or GERAN deployment scenario: In this scenario it is assumed that the operator is having either a UTRAN and/or a GERAN network deployed with full or partial coverage in the same geographical area. It is assumed that the GERAN and UTRAN networks respectively can have differently levels

49、 of maturity. In order to enable the large number of possibilities, E-UTRAN will support the following: 1) shared networks, both in initial selection and in mobile-initiated (controlled by system broadcast) and network-initiated/controlled mobility. 2) high-velocity and nomadic mobiles. Mobility mechanisms include a handover mechanism with short latency, short interruption and minimizing of data losses (when the user has high data activity). Hence both high mobile velocities and Conversational QoS can be supported (as elaborated in 13.6). 3)
