Semiconductor devices may include a peripheral circuit structure including circuits, a substrate on the peripheral circuit structure, a pair of word line cut structures extending in a first direction on the substrate, and a memory cell block between the pair of word line cut structures and on the substrate. The memory cell block may include a memory stack structure including gate lines overlapping each other in a vertical direction, an interlayer insulation layer on an edge portion of each of the gate lines, a dam structure extending through the gate lines and the interlayer insulation layer, an intersection direction cut structure extending through the memory stack structure and the interlayer insulation layer in the vertical direction and being spaced apart from the dam structure, and a dummy channel structures between the intersection direction cut structure and the dam structure.

Semiconductor devices and electronic systems including the same

Disclosed are an apparatus and a method for selecting a beam in an electronic device. An electronic device includes: a plurality of antennas configured to form beams in different directions; and at least one processor, wherein the at least one processor is configured to: control the plurality of antennas to form a wide beam, determine a transmission beam pattern of a transmitting side through the wide beam, control the plurality of antennas to form a reception beam, and determine a reception beam pattern to be used for receiving a signal from the transmitting side.

Method of selecting beam and electronic device thereof

A method for a data signal on channels having spatial correlations by a Base Station (BS) is provided. The method includes estimating the spatial correlations of the channels, selecting a part of the channels based on a result of the estimation and transmitting a signal for channel estimation on the selected partial channels, and receiving channel estimation information estimated based on the signal from a User Equipment (UE) and generating a data signal to be transmitted to the UE on the channels using the channel estimation information.

Method and apparatus for transmitting feedback about channel having spatial correlation

The present disclosure relates to a method and an apparatus for transmitting and receiving channel related information. A method of transmitting channel related information of a UE according to an embodiment of the present disclosure includes configuring a sub-channel corresponding to a part of a plurality of antennas of an eNB; acquiring a Channel Estimation Error (CEE) and a Precoding Matrix Indicator (PMI) corresponding to the sub-channel; and transmitting a Sub-channel Indicator (SI) indicating the sub-channel, according to the CEE and the PMI. In accordance with an embodiment of the present disclosure, the channel related information is efficiently transmitted and received in a system in which a plurality of antennas is used.
