A mobile robot rotates a spin mop to move a main body along a surface and clean the surface. A location change of the main body during its motion is analyzed to determine if the robot is traveling abnormally. If abnormal traveling is occurring, the location where it is occurring is stored and re-cleaning of the location is initiated. The location where abnormal traveling occurred may be considered in next cleaning to improve cleaning efficiency.

Moving robot and control method thereof

A method and an apparatus for transmitting or receiving a reference signal in a wireless communication system are disclosed. A method of receiving a tracking reference signal (TRS) by a terminal in a wireless communication system according to an embodiment of the present disclosure may comprise: receiving, from a network, at least one of first offset information related to at least one burst of the TRS, or second offset information related to the at least one burst; and receiving, from the network, the TRS in the at least one burst, wherein the first offset information is related to a first burst of the at least one burst, wherein, based on the second offset information being absent, a number of the at least one burst is one, and wherein, based on the second offset information being present, the second offset information indicates an offset between the first burst and a second burst.

Method and apparatus for transmitting or receiving reference signal in wireless communication system

A robot cleaner according to the present invention includes a body provided with a driving unit for movement, a position recognition unit provided in the body to recognize a position of the body, a storage unit configured to store, on a map, a region cleaned while the body is moving by the driving unit, and a control unit configured to control the driving unit, wherein the control unit determines whether a charging stand exists in a cleaning completed region on the map stored in the storage unit when a return condition that the body returns to the charging stand is satisfied, searches for an uncleaned region when the charging stand is not located in the cleaning completed region, and controls the driving unit such that the body moves from a current position to a point in a found uncleaned region or a point around the found uncleaned region.

Robot cleaner and control method thereof

A autonomous robot includes a main body, a driving unit to move the main body within an operation region, a battery to supply power to the driving unit, and a controller to control the driving unit in a manner that the main body travels along a wall of the operation region to move to a charging stand when a remaining power level of the battery drops below a reference power level, wherein the controller controls the driving unit in a manner that the main body escape from one region corresponding to a closed curve when a movement path of the main body forms the closed curve while the driving unit performs wall following.

Moving robot and method of controlling the same

A method for configuring bit rate in a user equipment (UE) for use in a wireless communication system includes receiving guaranteed bit rate information comprising one or more bit rates which are supported by a base station (BS) for communications with the UE, selecting a minimum guaranteed bit rate responsive to user input received at the UE, the minimum guaranteed bit rate being a bit rate identified by the guaranteed bit rate information, generating a first request message requesting the selected minimum guaranteed bit rate, transmitting the first request message from the UE to the BS, the first request message including a request for receiving communications from the BS at the selected minimum guaranteed bit rate, receiving a response message from the BS in response to the first request message, and receiving data from the BS at a bit rate which is at or greater than the selected minimum guaranteed bit rate when the response message comprises an acknowledgement (ACK) message.

Method and apparatus for configuring minimum guaranteed bit rate in wireless communication system

A mobile station provided with multiple antennas in a wireless communication system is disclosed. More specifically, the mobile station displays an overlap zone entry notification message received from a macro base station if the mobile station enters an overlap zone between the macro base station and a femto base station, and an user selects an antenna driving mode of the multiple antennas. And then, the mobile station transmit and receive signals to and from at least one of the macro base station and the femto base station in accordance with the selected antenna driving mode.

Method for transceiving signal in mobile station in multiple antenna wireless communication system and apparatus therefor

A method for performing roaming in a dual mode terminal, which includes a first wireless communication module corresponding to a first communication network and a second wireless communication module corresponding to a second communication network, is disclosed. The method comprises acquiring a public land mobile network (PLMN) identifier by camping on the first communication network; determining whether connection to the first communication network is roaming by comparing roaming decision information included in the PLMN identifier with roaming decision information stored in the dual mode terminal; turning off the second wireless communication module if it is determined that connection to the first communication network is roaming; and transmitting and receiving a signal to and from the first communication network.

Method for restricting communicating service in roaming in multi mode terminal and apparatus therefor
