1. A method of operating an ultra-wide band (UWB) device, the method comprising:
receiving, by a UWB subsystem (UWBS) of the UWB device, a first UWB subsystem command interface (UCI) message including first configuration information for downlink time difference of arrival (DL-TDoA) ranging, wherein the first configuration information includes a list of at least one index of at least one active ranging round in which the UWBS listens for at least one DL-TDoA Message (DTM) from at least one anchor device;
receiving, by the UWBS. a second UCI message including second configuration information. wherein the second configuration information includes block striding information indicating a number of ranging blocks to be skipped;
receiving, by the UWBS, at least one DTM based on the list of the at least one index and the block striding information; and
determining a location of the UWB device based on the at least one DTM.
