An electronic apparatus for providing proximity-based information according to various embodiments of the present invention comprises: a communication interface; a memory; and a processor electrically connected to the communication interface and the memory, wherein the processor may be set to obtain first context information from one or more programs running on the electronic apparatus, identify first location information corresponding to the first context information, transmit, to a server, first data including at least one of the first context information and the first location information, through the communication interface, receive, from the server, first event information on a point of interest corresponding to the transmitted first data, and store, in the memory, the received first event information on the point of interest. Other various embodiments are possible.

Method and apparatus for providing proximity-based information

Embodiments herein provide methods and systems for achieving D2D communications through unlicensed spectrum. The D2D-U operations can be achieved through multiple approaches. In the first approach, the devices can communicate with each other without any involvement of network. In the second approach, the network provides partial assistance to the devices such as allocating time and frequency resources for D2D-U communication. In the third approach, the network completely controls D2D-U operations between the devices. The embodiments include allocating time and frequency resources for transmission of PSBCH, PSDCH, PSCCH, and PSSCH. The allocations of the time and frequency resources meet regulatory requirements of minimum bandwidth utilization for unlicensed band operation. The embodiments include distributing power in narrow frequency sub-bands of D2D-U spectrum, in order to maximize transmission range of D2D-U communications.

Methods and systems for D2D operation in unlicensed spectrum

An electronic device according to various embodiments of the present invention may comprise: a communication circuit for communicating with at least one network; and a processor configured to obtain a location estimation region of the electronic device on the basis of the at least one network, via the communication circuit, and to determine whether the electronic device has entered a region of interest, on the basis of a correlation between a probability distribution for the obtained location estimation region and a probability distribution for a preset region of interest, wherein various embodiments are possible.

Electronic device and method for determining entry of region of interest of electronic device

Disclosed are a method and an apparatus for managing a Point of Interest (POI) using a tile. An electronic device includes a memory; and a processor, wherein the processor is configured to receive map information of a cellular base station including a plurality of tiles from at least one server, determine a location of the electronic device based on the received map information, identify at least one tile corresponding to the location of the electronic device based on a request of the processor for configuring a POI, and obtain a first search list of POIs included in the at least one identified tile.

Method and apparatus for managing point of interest based on tile

A method for communication in an electronic device is provided. The method includes determining whether to control a communication module of the electronic device based on information related to communication between the electronic device and an external device, determining a control value for the communication module based on the determination, and controlling the communication module using the control value.

Apparatus and method for providing communication

An apparatus for iteratively estimating a channel in a receiver of a wireless communication system is provided. The apparatus includes a channel estimator configured to estimate a first channel value by using a pilot symbol included in a received signal, a demodulator configured to demodulate the received signal by using the first channel value, a decoding unit configured to decode the received signal demodulated by the demodulator, a feedback determining unit configured to determine whether to iteratively estimate the channel, and a feedback device configured to feed back an input value of the decoding unit when the feedback determining unit determines to iteratively estimate the channel, wherein when the feedback determining unit determines to iteratively estimate the channel, the channel estimator estimates a second channel value by using at least one of the pilot symbol included in the received signal and a data symbol received from the feedback device.
