b) The 880-915 MHz band is allocated for the uplink band, divided into four blocks B1, B2, and B3 with corresponding bandwidths of 10 MHz, 8.4 MHz, 8.2 MHz, and 8.2 MHz;₁, B₂, B₃ and B₄ with corresponding bandwidths of 10 MHz, 8.4 MHz, 8.2 MHz and 8.2 MHz;

c) The 925-960 MHz band is allocated for the downlink band, divided into four blocks B1', B2', and B3' with corresponding bandwidths of 10 MHz, 8.4 MHz, 8.2 MHz, and 8.2 MHz;₁’, B₂’, B₃’ and B₄’ with corresponding bandwidths of 10 MHz, 8.4 MHz, 8.2 MHz and 8.2 MHz;

d) The maximum total bandwidth that an organization may be licensed to use in the 880-915 MHz and 925-960 MHz bands under the FDD method is 2×10 MHz;

e) Organizations licensed to use the band within the 880-915 MHz and 925-960 MHz bands must cooperate with each other to prevent and handle harmful interference;

f) To avoid causing harmful interference to other permitted radio systems operating in certain areas within the 880-915 MHz and 925-960 MHz bands, organizations licensed to use the band within these bands must implement technical measures to address harmful interference in accordance with the guidance of the Ministry of Information and Communications (Radio Frequency Management Department).
