    • A method for maintaining adjacent cell coordination between one or more adjacent cells and a wireless mobile communication device in a communication system, wherein non-programmed radio windows of a data frame are made available to receive control channel coordination bursts used in the initial or ongoing synchronization of the adjacent cell. In at least one embodiment, one or more programmed radio window of the data frame are reorganized, such as the placement of an adjacent channel power measurement burst between a downlink traffic burst and an uplink traffic burst, so as to increase the portion of the data frame, which is available for receiving control channel coordination bursts. In at least further embodiments, where there is no data to communicate as part of an uplink traffic burst, such as during a discontinuous data channel transmission, the portion of the data frame previously assigned to the uplink traffic burst is reclassified as a non- programmed radio window during which a control channel coordination burst can be received.

    • The present invention relates to a method and arrangement in an ad-hoc network for synchronizing a multiple of radio transceiver arrangements with different characteristics that make use of a common air interface. Each transceiver arrangement comprises at least two transceivers which mutually communicate via a radio transmission link. All transceivers synchronize to a common synchronization signal comprising two staggered beacon pulse series signals (TX1, TX2) which have the same repetition rate. The transceivers synchronize their internal timers which control the signal transmission from the transceivers, to the strongest one of the two beacon pulse series signals (TX1, TX2) by listening during one of the corresponding sets of time windows (RX1, RX2). Between the reception of two beacon pulses, each transceiver transmits beacon pulses itself, thus contributing to the generation of the other beacon pulse series signal, on which other transceivers can lock.

    • A method for synchronizing overlapping cells covered by different base stations include obtaining a propagation delay between a first base station and a second base station, scheduling by the first base station a selected one of first users located in a first cell covered by the first base station to transmit a first data packet which is a part of a transmission data frame, transmitting at the selected one the first users a transmission offset indicating the difference in a time domain between the beginning of the transmission data frame and the first data packet, in response to the reception of the first data packet, recording a reception offset at a selected one of second users located in a second cell covered by the second base station, the reception offset indicating the difference in time domain between the beginning of a reception data frame and the first data packet, transmitting at the selected one of the second users the reception offset to the second base station, calculating at the second base station a frame slide by adding the transmission offset and the propagation delay, and subtracting the reception offset, and synchronizing the first cell and the second cell based upon the calculated frame slide.
