This radio equipment type is capable of operating in all or any part of the frequency bands given in table 1-1. Table 1-1: UTRA FDD Base Station operating bands UTRA FDD band Direction of transmission UTRA FDD Base Station operating bands I Transmit 2 110 MHz to 2 170 MHz Receive 1 920 MHz to 1 980 MHz III Transmit 1 805 MHz to 1 880 MHz Receive 1 710 MHz to 1 785 MHz VII Transmit 2 620 MHz to 2 690 MHz Receive 2 500 MHz to 2 570 MHz VIII Transmit 925 MHz to 960 MHz Receive 880 MHz to 915 MHz XV Transmit 2 600 MHz to 2 620 MHz Receive 1 900 MHz to 1 920 MHz XVI Transmit 2 585 MHz to 2 600 MHz Receive 2 010 MHz to 2 025 MHz XX Transmit 791 MHz to 821 MHz Receive 832 MHz to 862 MHz XXII Transmit 3 510 MHz to 3 590 MHz Receive 3 410 MHz to 3 490 MHz XXXII (see note) Transmit 1 452 MHz to 1 496 MHz Receive - NOTE: The down link frequenc(ies) of this band are paired with the uplink frequenc(ies) of the other FDD band (external) of the dual band configuration. The present document covers requirements for UTRA FDD Base Stations for 3GPP Releases 99, 4, 5, 6, 7, 8, 9, 10 and 11. This includes the requirements for BS operating bands from 3GPP Release 12. In addition, the present document covers requirements for UTRA FDD Base Stations in the operating bands specified in ETSI TS 102 735 [i.4]. The present document contains requirements to demonstrate that Radio equipment both effectively uses and supports the efficient use of radio spectrum in order to avoid harmful interference.
