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 device and method in a wireless communication system, the device including an access determination unit configured to determine an access requirement of a user equipment (UE); and a control unit configured to switch a target small cell of the device from a closed state to an open state based on the access requirement of the UE, and reallocate to the target small cell a new physical cell identifier different from the physical cell identifier used in the closed state. A physical cell identifier can be dynamically allocated in accordance with the open/closed state of the small cell, reducing the burden of cell planning and maintenance cost, and having greater flexibility.
