 FDD and TDD modes). Table 5.3 summa- rizes the specified channel configurations: The UTRA Transmission System Table 5.3 UTRA Channel Configurations FDD (MHz) TDD (MHz) Channel: UE and BS UE and BS Spacing 5 MHz 5 MHz Raster 200 kHz 200 kHz Number N = 5 X (F - MHz) 0.0 MHz Fuplink 3276.6 MHz 0.0 MHz F 3276.6 MHz Nd=5x(1Fdownlink MHz) F is the carrier frequency in MHz MHz Fdownlink 3276.6 Fuplink Fdownlink are the uplink and downlink frequencies in MHz, respectively. The nominal channel spacing (i.e. 5 MHz) can be adjusted to optimize performance depending on the deployment scenarios; and the channel raster (i.e. 200 kHz) implies the centre frequency which must be an integer multiple of 200 kHz. In the case of the channel number, the carrier frequency is designated by the UTRA Absolute Radio Frequency Channel Number (UARFCN), Table 5.3 shows those de- fined in the IMT2000 band. TRANSMITTER CHARACTERISTICS As in the UE or otherwise stated, we specify transmitter characteristics at the BS an- tenna connector (test port A) with a full complement of transceivers for the configura- tion in normal operating conditions. When using external apparatus (e.g. TX amplifiers, diplexers, filters or a combination of such devices, requirements apply at the far end antenna connector (port B). 5.3.1 Maximum Output Power 5.3.1. User Equipment (UE) At this time detailed transmitter characteristics of the antenna connectors in the UE are not available; thus, a reference UE with integral antenna and antenna gain of 0 dBi is as- sumed. For the definition of the parameters to follow we use the UL reference measure- ment channel (12.2 kbps) illustrated in Table 5.4, other references can be found in [1,2].
