1. A method, comprising:
in a relay device that comprises a plurality of antenna arrays:
receiving a signal from a source device;
measuring signal power of the received signal;
selecting, based on the measured signal power, a first set of antenna arrays in the plurality of antenna arrays to establish a first link between the relay device and the source device, wherein the signal is received through the first link;
selecting a second set of antenna arrays in the plurality of antenna arrays to establish a second link between the relay device and a destination device, wherein the second set of antenna arrays is selected based on a distance between the relay device and the destination device;
selecting between an active mode or a passive mode of relay operation;
in the active mode of relay operation:
demodulating the received signal to obtain demodulated signal; and
transmitting the demodulated signal on the second link, wherein the signal is received concurrently with the transmitting of the demodulated signal; and
in the passive mode:
forwarding the received signal to the destination device on the second link without demodulating the received signal.
