ANNEX PART A TECHNICAL CONDITIONS FOR GSM-R IN 874,4-880,0 MHZ and 919,4-925,0 MHZ BANDS For GSM-R, the following parameters apply: GSM-R Downlink centre frequency f DL = 921 MHz + n × 0,2 MHz ( 1 ) where GSM-R Uplink centre frequency f UL = f DL – 45 MHz GSM-R channel bandwidth is 200 kHz Table 1 In-block requirements for GSM-R Base Stations in 919.4-921 MHz uncoordinated deployment GSM-R channel bandwidth Maximum EIRP 200 kHz = 70,5 dBm + (f DL – 921) × 40/3 dB f DL is the centre frequency in MHz There is no EIRP restriction on GSM-R Base Stations transmitting in the 921-925 MHz frequency band. Formula applicable to f DL ≤ 921 MHz. To allow higher EIRP the implementation of a coordination procedure or other mitigation measures must be applied. PART B TECHNICAL CONDITIONS FOR A SINGLE WIDEBAND RAILWAY MOBILE RADIO (RMR) CARRIER IN 874,4-880,0 MHZ and 919,4-925,0 MHZ BANDS Technical conditions for RMR Base Stations using wideband technologies The technical conditions defined in this section are in the form of a block-edge mask (BEM) applicable to wideband RMR Base Stations. The technical conditions defined in this section are valid for a single RMR carrier using wideband technologies. The BEM is developed on the basis that detailed coordination and cooperation agreements would not be required to be in place prior to network deployment. To allow multiple carriers or higher EIRP for RMR Base Stations than stated in the harmonised technical conditions, the implementation of a coordination procedure or other mitigation measures must be applied. Base Stations using active antenna systems are prohibited. For radio access technologies other than GSM-R, the following parameters apply: — The lower edge of the lowest Resource Block shall be ≥ 919,6 MHz Table 2 General in-block requirement – not mandatory RMR channel bandwidth Maximum EIRP For any channel bandwidth The following value may be used in case an upper bound is desired: = Min {65 dBm/channel, Maximum EIRP specific to the channel bandwidth} Table 3 Specific in-block requirements for 5,6 MHz and 5 MHz channels mandatory for uncoordinated deployment RMR channel bandwidth Maximum EIRP 5,6 MHz = 62 dBm/5,6 MHz 5 MHz = 64,5 dBm/5 MHz + (f DL – 922,1) × 40/3 dB (Note 1) f DL is the centre frequency in MHz. NB-IoT in-band operation mode without power boost is allowed. NB-IoT guard-band operation mode and in-band operation mode with power boost are not allowed. Note 1: The calculation has been based on 25 Resource Blocks. The formula equally applies to 20 Resource Blocks. Table 4 Specific in-block requirements for frequency channels of 3 MHz, and smaller than or equal to 200 kHz, which are mandatory for uncoordinated deployment RMR channel bandwidth Maximum EIRP 3 MHz = 61 dBm/3 MHz + (f DL – 921,4) × 40/3 dB (Note 1) 200 kHz (Note 2) = 70,5 dBm/200 kHz + (f DL – 921) × 40/3 dB (Note 3) f DL is the centre frequency in MHz. Note 1: Formula applicable to f DL ≤ 922,5 MHz. No specific EIRP restriction above 922,5 MHz. The calculation is based on 15 Resource Blocks. It equally applies to 12 Resource Blocks. Note 2: Applicable to narrowband technologies. Note 3: Formula applicable to f DL ≤ 921,0 MHz. No specific EIRP restriction above 921 MHz. Table 5 Out-of-band requirements MHz from block edge (919.4-925 MHz) EIRP limit 0 ≤ Δf < 0.2 32,5 dBm/200 kHz 0,2 ≤ Δf < 1 14 dBm/800 kHz 1 ≤ Δf < 10 5 dBm/MHz On a case-by-case basis, at a national level, higher out-of-band limits may be applied. Table 6 Baseline requirement Frequency range EIRP limit 880-915 MHz -49 dBm/5 MHz This requirement prevails over out-of-band requirements.
