摘要：
A communication system includes first and second devices, where a processor of at least one of the first device and the second device is configured to establish a superframe having a superframe duration (Ts) and transmit a beacon by the first device during each of the superframe duration (Ts); scan by the second device all sectors (Nbeam) by scanning each sector for a superframe duration (Ts) and repeating a jump sequence. The jump sequence has a sequence duration (Ttotal) which is equal to a sum of a control duration (Tc) of a control channel and durations of data channels (KTd). The processor is further configured to find the first device by the second device during a find time (Tf), where the control duration (Tc) is greater than the durations of data channels (KTd).
