1. A method for a connectionless asset tracking service in a wireless communication system, the method comprising:
receiving, by a first device, an advertising packet from a second device;
detecting, by a host of the first device, that at least one advertising data structure (AD structure) included in the advertising packet is an AD structure related to the connectionless asset tracking service based on determining that an AD type field of the AD structure includes a value indicating the connectionless asset tracking service; and
determining, by the first device, a location based on the AD structure related to the connectionless asset tracking service,
wherein the AD structure includes an AD length field, the AD type field, and an AD data field,
wherein the AD data field of the AD structure related to the connectionless asset tracking service includes pseudo-noise data used for measuring an angle of arrival (AoA) related to the connectionless asset tracking, and
wherein, before the host determines that the AD type field of the AD structure includes the value indicating the connectionless asset tracking service, a controller of the first device samples and stores the advertising packet including the AD structure in a buffer.
