RES749 – 396 – emphasizing a) that the use of the frequency band 470-862 MHz by broadcasting and other primary services is also covered by the GE06 Agreement; b) that the requirements of the different services to which the frequency band is allocated, including the mobile, aeronautical radionavigation (in accordance with No. 5.312), fixed and broadcasting services, shall be taken into account, taking into account that the results of the studies carried out by ITU-R pursuant to Resolution 749 (WRC-07) indicate that there is a need to protect other primary terrestrial services from the mobile service in Region 1, resolves 1 that in Region 1:in accordance with No. 5.316B, and based on the criteria contained in Annex 1 to this Resolution, administrations implementing the mobile service in Region 1 shall seek agreement under No. 9.21 with respect to the aeronautical radionavigation service in the countries mentioned in No. 5.312 of the Radio Regulations; 2 that for Region 1 and Iran (Islamic Republic of): 2.1 when coordination between administrations is being effected, the protection ratios applicable to the generic case NB contained in the GE06 Agreement for the protection of the broadcasting service shall be used only for mobile systems with a bandwidth of 25 kHz. If another bandwidth is used, the relevant protection ratios are to be found in Recommendations ITU-R BT.1368 and ITU-R BT.2033; 2.2 to invite administrations to take into account, inter alia, the results of the sharing studies conducted by ITU-R in response to Resolution 749 (WRC-07); 3 that with respect to adjacent channel interference within the frequency band 790-862 MHz:3.1 adjacent channel interference within a given country is a national matter and needs to be dealt with by each administration as a national matter;3.2 adjacent channel interference should be treated among administrations concerned, using mutually agreed criteria or those contained in relevant ITU-R Recommendations (see also the most recent versions of Recommendations ITU-R BT.1368, ITU-R BT.1895 and ITU-R BT.2033 when sharing with the broadcasting service is concerned), as appropriate, invites administrations to contribute further to the studies conducted by ITU-R in accordance with recognizing k) above, instructs the Director of the Radiocommunication Bureau to implement this Resolution and to take appropriate actions.
