               1. A motion sensing method comprising: 
            at a first wireless communication device, receiving wireless signals transmitted from a second wireless communication device through a space during a time period; 
                by operation of the first wireless communication device: 
              generating channel state information based on the wireless signals; 
                  detecting that the first wireless communication device moved relative to the second wireless communication device during the time period; 
                  in response to detecting that the first wireless communication device moved relative to the second wireless communication device during the time period, updating motion sensing parameters of a motion sensing system; and 
                  processing the channel state information according to the updated motion sensing parameters to detect motion of an object, other than the first wireless communication device, in the space during the time period.
