§  27.1607   Information sharing for time division duplex synchronization.

   (a) 3.45 GHz Service licensees must provide information to requesting
   Citizens Broadband Radio Service (part 96 of this chapter) operators to
   enable time division duplex (TDD) synchronization. Negotiations over
   the information must be conducted in good faith, with the goal of
   enabling synchronization between the relevant systems.

   (1) A Citizens Broadband Radio Service operator, whether a Priority
   Access Licensee or a General Authorized Access user (§ 96.1(b) of this
   chapter), may request information from a 3.45 GHz Service licensee to
   enable cross-service TDD synchronization if it provides service, or
   intends to provide service, in the same or adjacent geographic area as
   a 3.45 GHz Service licensee.

   (2) Upon request by an eligible Citizens Broadband Radio Service
   operator, the 3.45 GHz Service licensee must provide sufficient
   technical information to allow the Citizens Broadband Radio Service
   operator to synchronize its system with the 3.45 GHz band system. The
   3.45 GHz Service licensee must keep this information current if its
   network operations change.

   (b) 3.45 GHz Service licensees are under no obligation to make any
   changes to their operations or proposed operations to enable TDD
   synchronization.
