A cellular wireless system using a single frequency OFDMA channel. Base stations include means for synchronization in frequency and time for control purposes. The synchronization means include same Frame numbers and slot index and same reference clock. In a cellular wireless system using a single frequency OFDMA channel, wherein base stations include means for synchronization in frequency and time for control purposes, a method for organizing data and pilots into sub-channels comprising pilots allocations among BSs. The method may further include taking the variable pilots and performing the allocation while shifting through time.
