Abstract: A radio frequency tag-based user interactive Internet of Things verification method, apparatus and system. Compared with the prior art, according to the method, interaction with a user (15) who orders a commodity (14) is performed to obtain a user password which is set by a user (15) or determined by a network device (11) and sent to the user (15); the user password and chip feature information of a radio frequency tag (13) are verified together, so that the user password is introduced into anti-counterfeiting verification of the radio frequency tag (13) by means of the interaction with the user (15). Because the user (15) can actively participate in anti-counterfeiting of a commodity (14), a platform party is prevented from operating an anti-counterfeiting system unilaterally; an Internet of Things method and a server verification technology are utilized to ensure that a chip can uniquely refer to a specific commodity, and replacement and/or repeated use are/is avoided; even if the user password is leaked, a third party rewrites the same content by using a chip in the same format, or a chip tag is replaced and repeatedly used, the solution can directly detect, and a commercial, complete and effective commodity anti-counterfeiting system is formed.

Abstract: Systems and methods for using a relay user equipment (UE) to transport data of interest received from a first remote UE to a second remote UE on a UE to UE relay within a wireless communication system are discussed herein. These methods may be performed at Layer 2 of a protocol stack of the wireless communication system. Data packets sent on the UE to UE relay may include an adaptation header including routing information (e.g., Layer 2 addresses, a bearer-specific index, etc. ) for the UE to UE relay. An adaptation layer may accordingly be provided within Layer 2 to decode these adaptation headers. In some cases, a per-bearer approach may be used to map between individual direct bearers of a hop by hop path configuration of the UE to UE relay. Embodiments eschewing the adaptation header and instead using logical channel identifiers (LCIDs) to make routing indications are also described.
