10、hird digit is incremented when editorial only changes have been incorporated in the specification; Introduction This document summarises the requirements for the UMTS Terrestrial Radio Access concepts. The purpose of this document is to enable the proposals for UTRA technologies to be developed and
11、evaluated. UMTS 21.01 will be developed to give further details on the UMTS radio requirements. 5 Key Requirements Maximum User Bit Rates =lexibility Handover TR 101 398 V3.0.1 (1998-10) Description Bearer capabilities The UTRA should support a range of maximum user bit rates that depend upon a user
12、s current environment as follows: Rural Outdoor1: at least 144 kbitls (goal to achieve 384 kbiffs), maximum speed: 500 kmRi Suburban Outdoor? at least 384 kbps (goal to achieve 512 kbitls), maximum speed: 120 km/h Indoor/Low range outdoo?: at least PMbps, maximum speed: 10 km/h It is desirable that
13、the definition of UTRA should allow evolution to higher bit rates. Negotiation of bearer service attributes (bearer type, bit rate, delay, BER, up/down link symmetry, protection including none or unequal protection), parallel bearer services (service mix), real-time / non-real-time communication mod
14、es, adaptation of bearer service bit rate Circuit and packet oriented bearers Supports scheduling (and pre-emption) of bearers (including control bearers) according to priority Adaptivity of link to quality, traffic and network load, and radio conditions (in order to optimisi the link in different e
15、nvironments). Wide range of bit rates should be supported with suff icient granularity Variable bit rate real time capabilities should be provided. Bearer services appropriate for speech shall be provided. Provide seamless ( to user ) handover between cells of one operator. The UTRA should not preve
16、nt seamless HO between different operators or access networks. Efficient handover between UMTS and 2nd generation systems, eg GSM, should be possible. 1 Compatibility with services provided by present Core Transport Networks Key requirements ATM bearer services GSM services IP (internet protocol) ba
17、sed services B/N-ISDN services The following table summarises all the key requirements identified for UMTS Terrestrial Radio Access concept: NOTE: Not all combinations of options are required; for details see UMTS 21.01 (ETSI TR 101 11 1). Radio Access Network Planning Public network operators Priva
18、te and residential operators J If radio resource planning is required, automatic planning shall be supported. It shall be possible to guarantee pre-determined levels of quality-of-service and quality to public UMTS network operators, in the presence of other authorised UMTS users. The radio access s
19、cheme should be suitable for low cost applications where range, mobility and user speed may be limited. Multiple unsynchronised systems should be able to successfully coexist in the same environment. It should be possible to install basestations without Co-ordination. Frequency planning should not b

I loperational requirements I (continued) I I I The specified bit rate will be available throughout the operators service area, with the possibility of large cells 2 The specified bit rate will be available with complete coverage of a suburban or urban area, using microcells or smaller mac
21、rocells The specified bit rate will be available indoors and locallised coverage outdoors.

23、 sites, the associated network connections , signalling load and traffic The peak and average power and envelope variations have to be such that the degree of interference caused to other equipment is not higher than in todays systems. UMTS shall be operative at RF emission power levels which are in
24、 line with the recommendations related to electromagnetic radiation. The UMTS radio interface should be able to accommodate at least the same level of protection as the GSM radio interface does. Coexistence with other systems The UMTS Terrestrial Radio Access should be capable to Co-exist with other
25、 systems within the same or neighbouring band depending on systems and regulations Multimode implementation capabilities It should be possible to implement dual mode UMTWGSM terminals cost effectively. NOTE: the feasibility of spectrum sharing requires further study.
