Abstract
Embodiments of the present application provide a method, device, device, and system for identifying user equipment in unauthorized transmission. The method includes: the network device receives K first messages repeatedly transmitted by the first user equipment on resources used for unauthorized transmission at L, and sent DMRS corresponding to the K first messages respectively; the DMRS is the first user equipment Generated according to the first DMRS parameter set corresponding to the first user equipment; the network device parses the DMRS corresponding to the K first messages received respectively, and parses out the DMRS parameters corresponding to the K first messages respectively, and according to the parsed out The DMRS parameters, and the correspondence between the first user equipment and the first DMRS parameter set, identify the user equipment sending the first message as the first user equipment. The present application increases the number of user equipment carried in resources used for unlicensed transmission.
Description
technical field [0001] The present application relates to the field of communication technology, and in particular to a method, device, device and system for identifying user equipment in unauthorized transmission. Background technique [0002] Existing cellular communication systems, such as Global System for Mobile Communication (GSM), Wideband Code Division Multiple Access mobile communication system (Wideband Code Division Multiple Access, WCDMA), Long Term Evolution (Long Term Evolution, LTE) and other systems , the supported communication is mainly for voice and data communication. Generally speaking, a traditional base station (Base Station, BS) supports a limited number of connections and is easy to implement. It should be noted that in LTE (4G, fourth-generation mobile communication system), base stations can be called 4G base stations (eNodeB, eNB); in next-generation (5G, fifth-generation) mobile communication systems (also called new An air interface (New Radio...
