1. A method for motion sensing carried out by a sensing receiver including a transmitting antenna, a receiving antenna, and at least one processor configured to execute instructions, the method comprising:
receiving, by the at least one processor from a sensing initiator, a sensing configuration comprising at least a bitmap length;
receiving, by the at least one processor, a sensing transmission from the sensing initiator;
determining time domain channel representation information from the sensing transmission;
determining one or more time domain pulses of the time domain channel representation information as selected time domain pulses;
creating a bitmap according to the selected time domain pulses of the time domain channel representation information and the bitmap length;
creating a sensing measurement report including at least the bitmap and the selected time domain pulses; and
sending the sensing measurement report to the sensing initiator.
