Abstract: Provided are a device-to-device (D2D) group communication method and a device using the same. The method includes transmitting a scheduling request for D2D group communication to a base station, receiving first radio resource information for a status report of D2D data to be transmitted from the base station, transmitting a D2D buffer status report to the base station through a first radio resource, receiving second radio resource information including D2D resource allocation information necessary for the D2D group communication from the base station, and transmitting control information for the D2D group communication including a D2D group identifier (ID) as a device ID and D2D user data to two or more communication partner devices belonging to the D2D group.

Abstract: An operation method of a terminal may include: receiving, from a base station, an addition value KN, information on linear combination coefficient matrices for respective numbers of transport blocks, and configuration information on each linear combination coefficient matrix; dividing a source block into M transport blocks; selecting one linear combination coefficient matrix among the linear combination coefficient matrices based on M; generating (M+KN) network coding blocks by performing network coding on the M transport blocks with the selected one linear combination coefficient matrix; and transmitting, to the base station, messages each including one network coding block among the network coding blocks, a control index of the one linear combination coefficient matrix, and a preamble.

Abstract: Disclosed are operation methods of communication node supporting direct communications in network. The operation method may comprise generating control information which includes parameters used for transmitting and receiving data; transmitting, to a second UE, the control information through a physical sidelink control channel (PSCCH); and transmitting, to the second UE, the data through a physical sidelink shared channel (PSSCH) based on the parameters. Therefore, a performance of the network can be enhanced.

Abstract: Disclosed are methods and apparatuses for transmitting data using a random access procedure in a communication system. An operation method of a terminal in a communication system includes transmitting a first MsgA including an RA preamble #i and a payload to a base station; receiving, from the base station, a MsgB including information indicating that an RA preamble #k is reserved; and transmitting a second MsgA including the RA preamble #k and data to the base station in a preamble reservation period associated with the RA preamble #k.

IPC: H04L1/00
Abstract: An operation method of a first communication node in a communication system includes receiving a signal from a second communication node; demodulating the signal to obtain LLR values; calculating a first codeword based on the LLR values; selecting error patterns from among all error patterns based on Hamming weights; generating second codewords by applying the first codeword to each of the selected error patterns; and determining a codeword having a highest similarity to the first codeword among the second codewords as an optimal codeword.
