Abstract: In one embodiment, a RF signal repeater switchable between SISO and MIMO comprises: a controller; a first transmitter path switchably coupled to first donor and coverage antennas; a second transmitter path switchably coupled to second donor and coverage antennas; a first receiver path switchably coupled to the first donor and coverage antennas; a second receiver path switchably coupled to the second donor and coverage antennas. The controller configures the repeater for a MIMO TDD operating mode by: configuring the first transmitter path and the second receiver path to repeat at least a first MIMO channel of UE uplink RF signals and at least a first MIMO channel of base station downlink RF signals; and configuring the second transmitter path and the first receiver path to repeat at least a second MIMO channel of UE uplink RF signals and at least a second MIMO channel of base station downlink RF signals.

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.
