Abstract: A storage device includes a memory device including user memory blocks providing a user data region; and a controller configured to: map logical addresses used in a host to a portion of the user data region, and use a remaining portion of the user data region as an over-provisioning region, wherein the controller is further configured to control the memory device to: erase the user memory blocks based on a sanitize command from the host, provide, to the host, block address information of the user memory blocks based on a block address request from the host, access the user memory blocks based on block state check requests from the host, and provide, to the host, state information indicating whether the user memory blocks are erased according to access results.

Abstract: A communication method and apparatus for communicating with an intelligent base station in a wireless communication system are provided. An operation method of the intelligent base station includes determining whether reconfiguration of an intelligent base station group that supports a terminal is necessary, according to movement information of the terminal, the determination being performed by a first intelligent base station included in the intelligent base station group, when the first intelligent base station determines that reconfiguration of the intelligent base station group is necessary, transmitting a join request to join the intelligent base station group, to a nearby intelligent base station not included in the intelligent base station group, receiving a join approval message in response to the transmitted join request, and reconfiguring the intelligent base station group, based on the received join approval message.
