The disclosure relates to a method and a device for transmitting and receiving a signal by a base station or a terminal in a wireless communication system. Specifically, a method performed by a first device in a wireless communication system includes deriving an amplitude scaling factor based on a comparison between amplitude distribution of a pilot signal corresponding to a first time resource domain and the amplitude distribution of a data signal corresponding to a second time resource domain; and transmitting, to a second device, a physical channel including the pilot signal and the data signal and the amplitude scaling factor, wherein the pilot signal is transmitted with a power determined based on the amplitude scaling factor, and power compensation for the data signal is based on the amplitude scaling factor.

Pilot power control technology for compensating for nonlinearity of amplifier

A liquid crystal display may be manufactured by forming a first alignment layer on a first base substrate, forming a second alignment layer on a second base substrate, disposing liquid crystal on the first alignment layer or the second alignment layer, and combining the first base substrate and the second base substrate with each other. At least one of the first and second alignment layers may be formed by forming an alignment solution including an alignment agent and a cross-linking agent on the first or second base substrate. The alignment solution is cured at a first temperature to form an alignment layer. The base substrate is exposed to light or an electron beam to align the alignment layer. The alignment layer is baked at a second temperature. The first temperature is lower than a cross-linking reaction temperature of the cross-linking agent.

Method of manufacturing liquid crystal display

A method of aligning an alignment layer of a liquid crystal display (LCD) includes positioning a substrate on a stage; the substrate having the alignment layer provided thereon and the alignment layer including a plurality of alignment regions. Data identifying positions of the alignment regions relative to the alignment layer are loaded. A control signal for controlling a supply of light based on the loaded data identifying the positions of the alignment regions is generated. The light is supplied to the alignment regions according to the control signal and the alignment regions are aligned. The light is supplied from at least two different angles of incidence so that the alignment regions are aligned in at least two different directions.
