Abstract: A method of a first user equipment (UE) may comprise: receiving a downlink (DL) reference signal transmitted by a base station using a beam included in a beam candidate group to be used for sidelink (SL) communication with a second UE; measuring a DL reference signal received power (RSRP) of the DL reference signal; determining a transmit power of a beam included in the beam candidate group based on the measured DL RSRP; and transmitting SL data to the second UE with the determined transmit power.

Abstract: An operation method of a relay node may include: receiving, from a first communication node, first data composed of n bits; receiving, from a second communication node, second data composed of m bits; in response to determining that n is greater than m, generating first T-data of m bits excluding (n-m) bits from the n-bits of the first data and first R-data of (n-m) bits; generating third data by performing a network coding operation on the first T-data and the second data; transmitting the third data to the first communication node; and transmitting the third data and the first R-data to the second communication node.

Abstract: A fingerprint recognition sensor according to an exemplary embodiment of the present invention includes: a photo sensor for sensing light that is diffuse-reflected from a finger of a user and incident on the photo sensor, or that is transmitted through the finger and incident on the photo sensor; a first matrix positioned on the photo sensor and including a first opening; a second matrix positioned on the first matrix and including a second opening; and a cover layer including one surface contacting the finger and positioned on the second matrix, wherein, from among light that is diffuse-reflected from the finger and incident on the cover layer or that is transmitted through the finger and incident on the cover layer, light having an angle, formed by a normal line on the one surface of the cover layer and a path of the light incident on the cover layer, that is greater than a critical angle, sequentially passes through the second opening and the first opening and is incident on the photo sensor.
