1. A reconfigurable radio frequency (RF) signal repeater switchable between single-input-single-output (SISO) and multiple-input-multiple-output (MIMO) operating modes, the repeater comprising:
a repeater controller;
a first bidirectional transmitter path coupled to the repeater controller, and switchably coupled to a first donor antenna and a first coverage antenna;
a second bidirectional transmitter path coupled to the repeater controller, and switchably coupled to a second donor antenna and a second coverage antenna;
a first bidirectional receiver path coupled to the repeater controller, and switchably coupled to the first donor antenna and the first coverage antenna; and
a second bidirectional receiver path coupled to the repeater controller, and switchably coupled to the second donor antenna and the second coverage antenna;
wherein the repeater controller is adapted to configure the repeater for a MIMO time-division-duplex (TDD) operating mode by:
configuring the first bidirectional transmitter path and the second bidirectional receiver path to repeat at least a first MIMO channel of user equipment (UE) uplink RF signals and at least a first MIMO channel of base station downlink RF signals; and
configuring the second bidirectional transmitter path and the first bidirectional receiver path to repeat at least a second MIMO channel of user equipment (UE) uplink RF signals and at least a second MIMO channel of base station downlink RF signals.
