1. A base station, comprising:

  • a processor configured to determine a length and schedule of a silent period for each channel of a plurality of aggregated channels based on system information, wherein each channel of the plurality of aggregated channels is using unlicensed spectrum, and wherein a first silent period for a first channel of the plurality of aggregated channels is not scheduled to occur when a second silent period for a second channel of the plurality of aggregated channels is scheduled to occur;

    the processor further configured to select the first channel as a new primary channel when the second silent period occurs, wherein the new primary channel transmits data and acts as a common control channel for the plurality of aggregated channels during the second silent period, and wherein each of the remaining channels of the plurality of aggregated channels performs its respective silent period during the second silent period; and

    a transmitter configured to transmit the length and schedule of the silent period for each channel to at least one wireless transmit/receive unit (WTRU).
