Abstract: A base station side and user equipment side device and method in a wireless communication system, and a wireless communication system. The base station side device includes a processor configured to: respond to a random access request of the user equipment and determine that an access process initiated by the user equipment is a contention-based or a non-contention-based access process; and with respect to the contention-based access process, to prepare auxiliary access information for potential user equipment that has failed to access so that the user equipment that has failed to access and the base station can complete the access process based on interaction of auxiliary access information.

Abstract: A wireless communication equipment and a wireless communication method. The wireless communication equipment used for a user equipment side includes one or more processors. The processors are configured to determine indication information about a type of another user equipment carried in a synchronizing signal from the user equipment, the type including a first type and a second type. The processors are also configured to determine, based on the indication information, corresponding device-to-device communication operation of a user equipment aiming at another user equipment.

Abstract: Disclosed are a wireless communication device and a wireless communication method. The wireless communication device according to one embodiment comprises one or more processors. The processors are configured so as to: on the basis of auxiliary dissemination limitation information about a source device as an information dissemination source, acquire device information about candidate devices capable of establishing direct communication with the source device; on the basis of the locations of the source device and the candidate devices, select a target device for establishing direct communication with the source device from the candidate devices; and determine a transmission resource for direct communication with the target device and generate a transmission resource scheduling indication.
