Disclosed is a method of operating an air purifier by executing an artificial intelligence (AI) algorithm and/or a machine learning algorithm in a fifth generation (5G) environment connected for the Internet of Things. A method for operating an air purifier comprises determining whether an indoor situation is a situation in which protection of a filter is necessary based on sensor information from at least one sensor, in response to a determination that the indoor situation is the situation in which protection of the filter is necessary, suspending an air purifying function, and operating one or more ventilation devices. According to the present disclosure, it is possible to protect the air purifier from a situation in which a life of the filter of the air purifier can be drastically shortened.

Air purifier and operating method of the same

A method for wireless communication by a terminal, a method for wireless communication by a base station, the terminal, and the base station, are provided. The method for wireless communication by the terminal includes receiving first information comprising a muting subframe interval, a subframe offset, and a muting position of a resource element in a resource block, checking presence of a data in a subframe, determining the resource element to be muted in the subframe based on the muting subframe interval, the subframe offset, and the muting position, if the data is present, and receiving the data on a physical downlink shared channel (PDSCH) based on the result of the determining step.

Device and method for communicating channel state information reference signal (CSI-RS) in wireless communication system

A method and an apparatus are provided for transmitting channel state information (CSI) by a terminal in a communication system. The method includes receiving a first signal from a first serving cell; receiving a second signal from a second serving cell; calculating first CSI for the first serving cell based on the first signal; calculating second CSI for the first serving cell based on the first signal; calculating first CSI for the second serving cell based on the second signal; calculating second CSI for the second serving cell based on the second signal; transmitting the first CSI and the second CSI for the first serving cell respectively; and transmitting the first CSI and the second CSI for the second serving cell respectively.

Method and apparatus for sending and receiving channel state information in multiple-input multiple-output network wireless communication systems

In a wireless communication system, a control channel is required in order to use limited resources effectively. However, the control channel resource is part of the system overhead, and thus reduces the data channel resource used for data transmission. In the long term evolution (LTE) system based on OFDM, one sub frame the consists of fourteen OFDM symbols wherein a maximum of three OFDM symbols are used for the control channel resource and remaining eleven OFDM symbols are used for the data channel resource. Therefore, the quantity of energy that can be transmitted for the control channel resource is extremely limited compared to the data channel resource. For this reason, the coverage of the control channel becomes less than that of the data channel, and even if a user can successfully receive the data channel, reception failure of a control channel sometimes results in failure of data recovery. In the present invention, in order to expand the coverage of the control channel to at least the coverage of the data channel, the time resource of the transmission resource wherein the control channel is transmitted is expanded and allocated for sending and receiving the control channel. By way of methods for extending the time resource are provided a method wherein a plurality of sub frames are used to transmit one control channel, and a method wherein a part of a data channel is used for the control channel.

Method and apparatus for sending and receiving control channel in wireless communication system

The present invention relates to a method for transmitting a backhaul sub frame channel of a base station in a wireless communication system. The method for transmitting a backhaul sub frame channel according to one embodiment of the present invention comprises: creating a downlink relay control channel by coding downlink relay control information that is transmitted to a relay; allocating the created downlink relay control channel to a first slot of a semi-static resource region that is allocated to the relay; and transmitting, to the relay, a backhaul sub frame to which the channel is allocated. Compared to existing control channel transmission techniques, the present invention can minimize overheads. Moreover, the present invention also reduces control channel resources required during retransmission and for the transmission of multiple backhaul subframes.
