摘要： Control unit within a femtocell base station is arranged to detect a transmission collision situation and resolves it by adjusting the timing of the transmission signal and consequently the frame position gradually over time. The adjustment (or shift) is performed in a slow enough rate such that the User Equipments currently connected (camped) to the femtocell base station remain connected. Additionally, a method is also provided. The method comprises: detecting neighboring base stations; detecting frame boundaries of the transmitting signal of each detected neighboring base station; calculating optimal transmit position; setting transmit position to calculated optimal transmit position; and maintaining optimal transmit position by gradually adjusting transmit position over time. In case, detecting neighboring base stations is not possible, the method comprises: detecting absolute time drifting in view of an absolute accurate time reference and maintaining constant absolute transmit position by gradually adjusting transmit position over time.

摘要翻译： 毫微微小区基站内的控制单元被配置为检测传输冲突情况，并且通过随时间逐渐调整传输信号的定时和随之而来的帧位置来解决它。 以足够慢的速率执行调整（或移位），使得当前连接（驻留）到毫微微小区基站的用户设备保持连接。 此外，还提供了一种方法。 该方法包括：检测相邻基站; 检测每个检测到的相邻基站的发送信号的帧边界; 计算最优发射位置; 将发射位置设置为计算的最佳发射位置; 并通过逐渐调整发射位置来保持最佳发射位置。 在不可能检测相邻基站的情况下，该方法包括：通过绝对准确的时间参考来检测绝对时间漂移，并通过逐渐调整发射位置随时间而保持恒定的绝对发送位置。
