Patent ID: 8626186

Claim:
A femtocell base station, comprising: a femtocell base station control unit configured to generate a transmission signal exhibiting a plurality of periodic frames, wherein each frame exhibits frame boundaries and an active transmit signal within the frame boundaries, and wherein the active transmit signal includes a temporal transmit position being a start point of the transmission signal; and a collisions avoidance module configured to: detect neighboring base stations; detect frame boundaries of a signal transmitted by each of the detected neighboring base stations when neighboring base stations are detected; select the temporal transmit position such that a likelihood of collisions between transmit signals is minimized when neighboring base stations are detected; select the temporal transmit position to be a current transmit position added to a predefined number of chips when no neighboring base station are detected for a predefined period of time; set a transmit position to the selected temporal transmit position; and gradually adjust the selected temporal transmit position over time such that the likelihood of collisions between transmit signals remains minimized.
