1. A method of wireless communication operable at a transmitting device in a wireless network, comprising:
sensing a spectrum on a plurality of first beams following a first sequence of the plurality of first beams in a first frame of a plurality of frames, each of the plurality of frames comprising a sensing period for sensing the spectrum and an idle period for facilitating spectrum sharing with another wireless network and configured to forbid transmission of different beams;
selecting one or more beams of the plurality of first beams based on a result of sensing the spectrum in the sensing period of the first frame;
transmitting a signal in the first frame using the one or more beams in a time interval between the sensing period and the idle period of the first frame; and
sensing the spectrum on the plurality of first beams following a second sequence of the same plurality of first beams in a second frame of the plurality of frames, the second sequence being derived and different from the first sequence.
