1. A communication method, comprising:

  • determining a level of timing synchronization between a first access point and one or more neighboring access points;

    sending, from the first access point to an access terminal, a synchronization advertisement message that identifies the level of timing synchronization; and

    synchronizing, at the first access point, reference signal timing with at least one of the one or more neighboring access points based on the determining,wherein the reference signal timing corresponds to timing of a Discovery Reference Signal (DRS) Transmission Window (DTxW), andwherein the synchronizing comprises synchronizing the DTxW of the first access point and the at least one of the one or more neighboring access points to within a margin.
