To develop the E-UTRA standard, all the relevant scenarios need to be considered for the various aspects of operation and the most critical cases identified. The process may then be iterated to arrive at final parameters that meet both service and implementation requirements.The E-UTRA system is intended to be operated in the same frequency bands specified for UTRA. In order to limit the number of frequency bands to be simulated in the various simulation scenarios a mapping of frequency bands to two simulation frequencies (900 MHz and 2000 MHz) is applied. When using the macro cell propagation model ofTR25.942 [3], the frequency contributes to the path loss by 21*log10(f). The maximum path loss difference between the lowest/highest frequencies per E-UTRA frequency band and corresponding simulation frequency is shown in tables 4.1 and 4.2.Table 4.1: Simulation frequencies for FDD mode E-UTRA frequency bandsTable 4.2: Simulation frequencies for TDD mode E-UTRA frequency bandsIt can be observed that the difference of path loss between simulation frequency and operating frequency (except bands 7, 11 and 38) is in the worst case less than 0.8 dB for the downlink and less the 1,5 dB for the uplink. Hence the mapping of operating frequency to simulation frequency will provide valid results.The validity of simulations performed at 2 GHz for the 2.6 GHz bands 7 and 38 was already analyzed in TR 25.810. Considering the expected higher antenna gain in the 2.6 GHz band the difference in path loss is in the order of 1 dB what is comparable to the other frequency bands.4.1 Interference scenariosThis chapter should cover how the interference scenarios could occur e.g. BS-BS, UE-BS etc.4.2 Antenna ModelsThis chapter contains the various antenna models for BS and UE4.2.1 BS antennas4.2.1.1 BS antenna radiation patternThe BS antenna radiation pattern to be used for each sector in 3-sector cell sites is plotted in Figure 4.1.

Propagation models are adopted from [3] and [4] and presented in the following clauses.4.5.1 Received signalAn important parameter to be defined is the minimum coupling loss (MCL). MCL is the parameter describing the minimum loss in signal between BS and UE or UE and UE in the worst case and is defined as the minimum distance loss including antenna gains measured between antenna connectors. MCL values are adopted from [3] and [7] as follows:Table 4.4: Minimum Coupling LossesWith the above definition, the received power in downlink and uplink can be expressed as [3]: RX_PWR = TX_PWR – Max (pathloss – G_TX – G_RX, MCL) where:RX_PWR is the received signal power TX_PWR is the transmitted signal power G_TX is the transmitter antenna gain G_RX is the receiver antenna gain4.5.2 Macro cell propagation model – Urban AreaMacro cell propagation model for urban area is applicable for scenarios in urban and suburban areas outside the high rise core where the buildings are of nearly uniform height [3]:80dB (f)log 21(Dhb)log 18(R)log Dhb)104(140L 1010103+⋅+⋅-⋅⋅⋅-⋅=-where:R is the base station-UE separation in kilometres f is the carrier frequency in MHzDhb is the base station antenna height in metres, measured from the average rooftop levelConsidering a carrier frequency of 900MHz and a base station antenna height of 15 metres above average rooftop level, the propagation model is given by the following formula [4]:(R)37,6log 120,9L 10+=where:R is the base station-UE separation in kilometresConsidering a carrier frequency of 2000MHz and a base station antenna height of 15 metres above average rooftop level, the propagation model is given by the following formula:(R)37,6log 128,1L 10+=where:R is the base station-UE separation in kilometresAfter L is calculated, log-normally distributed shadowing (LogF) with standard deviation of 10dB should be added [2], [3].

This model is notvery accurate for short distances. NOTE 4: The mean building height is equal to the sum of mobile antenna height (1,5m) and 10,5m Δh m = [5]. NOTE 5: Some downlink simulations in this TR were performed without shadowing correlation, however it wasreported this has a negligible impact on the simulation results.4.5.3 Macro cell propagation model – Rural AreaFor rural area, the Hata model was used in the work item UMTS900[2], this model can be reused:L (R)= 69.55 +26.16log 10(f)–13.82log 10(Hb)+[44.9-6.55log 10(Hb)]log(R) – 4.78(Log 10 (f))2+18.33 log 10 (f) -40.94 where:R is the base station-UE separation in kilometres f is the carrier frequency in MHzHb is the base station antenna height above ground in metresConsidering a carrier frequency of 900MHz and a base station antenna height of 45 meters above ground the propagation model is given by the following formula:(R)34,1log 5,95L 10+=where:R is the base station-UE separation in kilometresAfter L is calculated, log-normally distributed shadowing (LogF) with standard deviation of 10dB should be added [2], [3].

Assumptions or E-UTRA in this chapter are based on the physical layer (OFDMA DL and SC-FDMA UL) as described in the E-UTRA study item report [4]. It must be noted that actual E-UTRA physical layer specification of frequency resource block is different regarding number ofsub-carriers per resource block (12 instead of 25 specified in [4]) and regarding the size of a resource block (180 kHz instead of 375 kHz in [4]). However, this has no impact on the results and conclusions of the present document.5.1.1 Simulation assumptions for co-existence simulations5.1.1.1 SchedulerFor initial E-UTRA coexistence simulations Round Robin scheduler shall be used.5.1.1.2 Simulated servicesWhen using Round Robin scheduler, full buffer traffic shall be simulated. For E-UTRA downlink, one frequency resource block for one user shall be used. The E-UTRA system shall be maximum loaded, i.e. 24 frequency resource blocks in 10 MHz bandwidth and 12 frequency resource blocks in 5 MHz bandwidth respectively. For E-UTRA uplink, the number of allocated frequency resource blocks for one user is 4 for 5 MHz bandwidth and 8 for 10 MHz bandwidth respectively.For the 5 MHz TDD UTRA victim using 3.84 Mcps TDD, Enhanced Uplink providing data service shall be used where 1 UE shall occupy 1 Resource Unit (code x timeslot). Here the number of UE per timeslot is set to 3 UEs/timeslot.Other services, e.g. constant bit rate services are FFS.5.1.1.3 ACIR value and granularityFor downlink a common ACIR for all frequency resource blocks to calculate inter-system shall be used. Frequency resource block specific ACIR is FFS.For uplink it is assumed that the ACIR is dominated by the UE ACLR. The ACLR model is described in table 5.1 and table 5.2Table 5.1: ACLR model for 5MHz E-UTRA interferer and UTRAvictim, 4 RBs per UETable 5.2: ACLR model for E-UTRA interferer and 10MHz E-UTRA victimNote: This ACLR models are agreed for the purpose of co-existence simulations. ACLR/ACS requirements need to be discussedseparately.5.1.1.4.1 Uplink Asymmetrical Bandwidths ACIR (Aggressor withlarger bandwidth)Since the uplink ACLR of the aggressor is measured in the aggressor’s bandwidth, for uplink asymmetrical bandwidth coexistence, a victim UE with a smaller bandwidth than that of the aggressor will receive a fraction of the interference power caused by the aggressor’s ACLR. For two victim UEs falling within the 1st ACLR of the aggressor, the victim UE closer in frequency to the aggressor will experience higher interference than one that is further away in frequency. The difference in interference depends on the power spectral density (PSD) within the aggressor’s 1st ACLR bandwidth. For simplicity, it is assumed that the PSD is flat across the aggressor’s ACLR bandwidth. Hence, the ACLR can be relaxed (or increased) by the factor, F ACLR:F ACLR = 10 × LOG10(B Aggressor/B Victim)Where, B Aggressor and B Victim are the E-UTRA aggressor and victim bandwidths respectively.20 MHz E-UTRA 5 MHz E-UTRAFigure 5.1: 20 MHz E-UTRA UE aggressor to 5 MHz E-UTRA UEvictims20 MHz E-UTRA 10 MHz E-UTRAFigure 5.2: 20 MHz E-UTRA UE aggressor to 10 MHz E-UTRAUE victimsIn Table 5.2, the aggressor UE that is non adjacent to the victim UE, the victim UE will experience an interference due to an ACLR of 43 + X –F ACLR. For the case where the aggressor UE is adjacent to the victim UEs, consider the scenarios in Figure 5.1, 5.2 and 5.3, where a 20 MHz E-UTRA aggressor is adjacent to 3 victim UEs of 5 MHz, 10 MHz and 15 MHz E-UTRA systems respectively.In Figure 5.1, all the UEs in the 5 MHz E-UTRA system will be affected by an ACLR of 30 + X - F ACLR. For the 10 MHz E-UTRA victims in Figure 5.2, two UEs will be affected by an ACLR of 30 + X - F ACLR whilst 1 UE will be affected by a less severe ACLR of 43 + X- F ACLR . In the 15 MHz E-UTRA victim as shown in Figure 5.3, the UE next to the band edge will be affected by an ACLR of 30 + X - F ACLR whilst the UE farthest from the band edge will be affected by an ACLR of 43 + X - F ACLR. The victim UE of the 15 MHz E-UTRA occupying the centre RB (2nd from band edge) is affected by 1/3 ACLR of 30 + X - F ACLR and 2/3 ACLR of 43 + X - F ACLR. This gives an ACLR of 34 + X - F ACLR.Using a similar approach for 15 MHz, 10 MHz and 5 MHz aggressor with a victim of smaller system bandwidth, the ACLR affecting each of the 3 victim UEs can be determined. This is summarised in Table 5.2A. Here the value Y is defined for victim UE, where ACLR = Y + X - F ACLR. UE1 is the UE adjacent to the aggressor, UE2 is located at the centre and UE3 is furthest away from the aggressor.。
