Abstract: One embodiment is directed to a repeater system configured for use with a base station that implements a wireless interface that makes use of control transmissions that are retransmittable (for example, LTE PRACH transmissions). The repeater system implements a simplified mute or squelch function that transitions the repeater circuitry from a muted state to an unmuted state in response to a received power level crossing a first threshold value in connection with a first control transmission. Although that first control transmission will be lost, the repeater circuitry is configured to remain in the unmuted state in order to handle a retransmitted control transmission and to handle any associated subsequent control and user transmissions. The repeater system can be implemented as a single-node repeater and/or a distributed antenna system. Other embodiments are disclosed.

Abstract: A switching control module can optimize time division duplexing operations of a distributed antenna system (“DAS”). The switching control module can include a measurement receiver and a processor. The measurement receiver can measure signal powers of downlink signals in a downlink path of the DAS. The processor can determine start times for downlink sub-frames transmitted via the downlink path based on downlink signal powers measured by the measurement receiver exceeding a threshold signal power. The processor can identify a clock setting that controls a timing of switching signals used for switching the DAS between an uplink mode and a downlink mode. The processor can statistically determine a switching time adjustment for the clock setting based on switching time differentials between the clock setting and the start times. The processor can update the clock setting based on the switching time adjustment.
