This excludes long-term beam shaping such as fixed electrical down tilt. In AAS base stations the antenna system is integrated as part of the base station system or product.\nNon-active antenna systems (non-AAS) means a base station and an antenna system that provides one or more antenna connectors, which are connected to one or more separately designed passive antenna elements to radiate radio waves. The amplitude and phase of the signals to the antenna elements is not continually adjusted in response to short term changes in the radio environment.\nEquivalent isotropically radiated power (EIRP) is the product of the power supplied to the antenna and the antenna gain in a given direction relative to an isotropic antenna (absolute or isotropic gain).\nTotal radiated power (TRP) is a measure of how much power a composite antenna radiates. It equals the total conducted power input into the antenna array system less any losses in the antenna array system. TRP means the integral of the power transmitted in different directions over the entire radiation sphere as shown in the formula:\nwhere P(θ,φ) is the power radiated by an antenna array system in direction (θ,φ) given by the formula:\nP(θ, φ) = PTxg(θ, φ)\nwhere PTx denotes the conducted power (measured in Watts), which is input into the array system, and g(θ,φ) denotes the array system’s directional gain along the (θ, φ) direction.\nB.\nGENERAL PARAMETERS\nWithin the paired terrestrial 2 GHz band, the frequency arrangement shall be as follows:\n(1) The duplex mode of operation is Frequency Division Duplex (FDD). The duplex spacing shall be 190 MHz with terminal station transmission (FDD uplink) located in the lower part of the band starting at 1 920 MHz and finishing at 1 980 MHz (“lower band”) and base station transmission (FDD downlink) located in the upper part of the band starting at 2 110 MHz and finishing at 2 170 MHz (“upper band”).\n(2) The assigned block size shall be in multiples of 5 MHz. The lower frequency limit of an assigned block in the lower band of 1 920-1 980 MHz shall be aligned with or spaced at multiples of 5 MHz from its lower edge of 1 920 MHz. The lower frequency limit of an assigned block in the upper band of 2 110-2 170 MHz shall be aligned with or spaced at multiples of 5 MHz from its lower edge of 2 110 MHz. An assigned block may also have a size in the range of 4,8-5 MHz as long as it fits within the boundaries of a 5 MHz block as defined above.\n(3) The lower band of 1 920-1 980 MHz or portions thereof, can be used for uplink-only operation without paired spectrum within the upper band of 2 110-2 170 MHz.\n(4) The upper band of 2 110-2 170 MHz or portions thereof, can be used for downlink-only operation without paired spectrum within the lower band of 1 920-1 980 MHz.\n(5) Base station and terminal station transmission shall be in compliance with the technical conditions specified in Part C and Part D, respectively.\nC.\nTECHNICAL CONDITIONS FOR BASE STATIONS – BLOCK EDGE MASK\nThe following technical parameters for base stations called Block Edge Mask (BEM) are an essential component of conditions necessary to ensure coexistence between neighbouring networks, in the absence of bilateral or multilateral agreements between operators of such neighbouring networks. Less stringent technical parameters, if agreed among all affected operators of such networks, may also be used provided that these operators continue to comply with the technical conditions applicable for the protection of other services, applications or networks and with obligations resulting from cross-border coordination.\nThe BEM consists of several elements given in Table 1. The in-block power limit is applied to a block assigned to an operator. The baseline power limit, designed to protect the spectrum of other operators, and the transitional region power limit, enabling filter roll-off from the in-block to the baseline power limit represent out-of-block elements.\nPower limits are provided separately for non-AAS and AAS. For non-AAS, the power limits apply to the mean EIRP. For AAS, the power limits apply to the mean TRP. The mean EIRP or mean TRP are measured by averaging over a time interval and over a measurement frequency bandwidth. In the time domain, the mean EIRP or mean TRP is averaged over the active portions of signal bursts and corresponds to a single power control setting. In the frequency domain, the mean EIRP or mean TRP is determined over the measurement frequency bandwidth as given in Tables 2, 3 and 4 below. In general, and unless stated otherwise, the BEM power limits correspond to the aggregate power radiated by the relevant device including all transmit antennas, except in the case of baseline and transition requirements for non-AAS base stations, which are specified per antenna.\nBlock Edge Mask (BEM)\nTable 1\nDefinition of BEM elements\nBEM element\nDefinition\nIn-block\nRefers to a block for which the BEM is derived.\nBaseline\nSpectrum within the FDD downlink frequency band used for WBB ECS, with the exception of block assigned to the operator and the corresponding transitional regions.\nTransitional region\nSpectrum within the FDD downlink within 0 to 10 MHz below and 0 to 10 MHz above the block assigned to the operator. The transitional regions do not apply below 2 110 MHz or above 2 170 MHz.\nTable 2\nIn-block power limits for non-AAS and AAS base stations\nIn a multi-sector base station, the AAS radiated power limit applies to each one of the individual sectors.\nBEM element\nFrequency range\nNon-AAS EIRP limit\nAAS TRP limit\nIn-block\nBlock assigned to the operator\nNot obligatory.\nIn case an upper bound is set by a Member State, a value of 65 dBm/(5 MHz) per antenna may be applied.\nNot obligatory.\nIn case an upper bound is set by a Member State, a value of 57 dBm/(5 MHz) per cell may be applied.\nExplanatory note to Table 2:\nThe corresponding in-block TRP limit is determined following guidelines given in ETSI TS 138 104 V15.6.0, Annex F, sections F.2 and F.3, on the basis of an antenna gain of 17 dBi and a total of eight beam forming antenna elements (scaling factor of 9 dB):\n65 dBm/(5 MHz) – 17 dBi + 9 dB = 57 dBm/(5 MHz).\nTable 3\nBaseline out-of-block power limits for non-AAS and AAS base stations\nThe non-AAS BEM level is defined per antenna and applicable to base station configuration with up to four antennas per sector.\nIn a multi-sector base station, the AAS radiated power limit applies to each one of the individual sectors.\nBEM element\nFrequency range within FDD downlink\nNon-AAS mean EIRP limit per antenna\nAAS mean TRP limit per cell\nMeasurement bandwidth\nBaseline\nFrequencies spaced more than 10 MHz from the lower or upper block edge\n9 dBm\n1 dBm\n5 MHz\nTable 4\nTransitional region out-of-block power limits for non-AAS and AAS base stations\nThe non-AAS BEM level is defined per antenna and applicable to base station configuration with up to four antennas per sector\nIn a multi-sector base station, the AAS radiated power limit applies to each one of the individual sectors.\nBEM element\nFrequency range within FDD downlink\nNon-AAS mean EIRP limit per antenna\nAAS mean TRP limit per cell\nMeasurement bandwidth\nTransitional region\n– 10 to – 5 MHz from lower block edge\n11 dBm\n3 dBm\n5 MHz\n– 5 to 0 MHz from lower block edge\n16,3 dBm\n8 dBm\n5 MHz\n0 to + 5 MHz from upper block edge\n16,3 dBm\n8 dBm\n5 MHz\n+ 5 to + 10 MHz from upper block edge\n11 dBm\n3 dBm\n5 MHz\nExplanatory note to Tables 3 and 4:\nIn alignment with the standardisation of unwanted emission conducted power (TRP) for AAS base stations in ETSI TS 138 104 (V15.6.0), Annex F, sections F.2 and F.3, the out-of-block TRP limits are set to a value that corresponds to a total of eight beam forming antenna elements, resulting in 8 dB difference between AAS and non-AAS as for the in-block case.\nD.\nTECHNICAL CONDITIONS FOR TERMINAL STATIONS\nTable 5\nTerminal station BEM in-block power limit\nThis power limit is specified as EIRP for terminal stations designed to be fixed or installed and as TRP for terminal stations designed to be mobile or nomadic. EIRP and TRP are equivalent for isotropic antennas. It is recognised that this value may be subject to a tolerance defined in the harmonised standards to take account of operation under extreme environmental conditions and production spread.\nMaximum mean in-block power\n24 dBm\nExplanatory note to Table 5:\nMember States may relax this limit for specific deployments, e.g. fixed terminal stations in rural areas provided that protection of other services, networks and applications is not compromised and cross-border obligations are fulfilled.’",
