1. based on a collocation method for the time division duplex modes between small areas of tdd systems, for eliminating the interference of the uplink/downlink signals between two neighbor cells that uplink/downlink physical frame ratio in same frequency range is different, it is characterised in that described method includes:

  • When the superframe-synchronized of said two neighbor cell, determine in the physical frame of said two neighbor cell overlapping in time domain and that transmission means is different one or more physical frames pair, one or two physical frame of each physical frame pair is set to not launch signal;

    Wherein, in all physical frame centerings determined, the ascending physical signal frame of same position in all of uplink transmission block is set to not launch signal, or the downstream physical frame of same position in all of downstream transmission blocks is set to not launch signal, or simultaneously by all of uplink transmission block same position ascending physical signal frame and in all of downstream transmission blocks the downstream physical frame of same position be set to not launch signal.
