1. A method of wireless communication by a repeater in a network, comprising:
receiving, via one or more of a plurality of input ports, one or more input signals carrying information;
mapping, via a mapping module, one or more of the plurality of input ports to a subset of a plurality of output ports based on feedback information associated with a plurality of output beam sweep procedures;
transforming, via the mapping module, each of the one or more input signals into two or more output signals carrying the information;
amplifying the two or more output signals;
adjusting, via the mapping module, phases of at least one of the two or more output signals such that the two or more output signals are coherently phased when received by a receiver; and
transmitting, via the subset of the plurality of output ports, the two or more output signals in a multiple-in multiple-out (MIMO) network.
