Abstract: A method of performing device-to-device (D2D) communication by a first device includes obtaining at least one measurement value corresponding to a relative velocity between the first device and a second device; adjusting at least one transmission parameter based on the at least one measurement value; providing the adjusted at least one transmission parameter to the second device; and transmitting data to the second device based on the adjusted at least one transmission parameter.

Abstract: A method may include, and/or a device may be configured for: receiving, from a transmitting device, a signal corresponding to input bits; performing demodulation based on the signal to determine values corresponding to the input bits; identifying a number of the input bits based on the signal; identifying a base matrix and a lifting size based on the number of the input bits; identifying a parity check matrix based on the base matrix; determining a number of layers based on the lifting size and a number of the values; determining an order of layers for low density parity check (LDPC) decoding based on the number of layers; and performing the LDPC decoding to determine the input bits based on the values, the parity check matrix, and the order of layers.

Abstract: Disclosed are a communication scheme and a system thereof for converging IoT technology and a 5G communication system for supporting a high data transmission rate beyond that of a 4G system. The disclosure can be applied to intelligent services (for example, services related to a smart home, smart building, smart city, smart car, connected car, health care, digital education, retail business, security, and safety) based on the 5G communication technology and the IoT-related technology. A decoding method includes: performing decoding through an inner code; detecting an error through an outer code; determining a re-encoding method; and performing re-encoding. A method for processing a signal includes decoding a first layer signal to determine first LDPC information bits, encoding the first LDPC information bits and a first parity bits to determine second parity bits; identifying a part of the first LDPC information bits, and decoding a second layer signal.
