Abstract: An operating method of a communication device for providing a beamformed transmission signal to a plurality of terminals may include determining a target transmission vector based on an area restriction condition for each of the plurality of terminals, generating a beam selection matrix for selecting some of a plurality of antennas based on the target transmission vector and a beam selection condition, generating a precoding matrix based on the target transmission vector and the beam selection matrix, and generating a transmission signal based on the beam selection matrix and the precoding matrix.

Abstract: An apparatus and a method for effectively mapping a reference signal for vehicle-to-everything (V2X) communication in a wireless communication system are provided. A transmission terminal performing the V2X communication includes a processor generating sidelink control information (SCI) and a transceiver transmitting the generated SCI to a reception terminal through a physical sidelink control channel (PSCCH) and a physical sidelink shared channel (PSSCH). A decision on whether to allocate a demodulation reference signal (DMRS) of the PSSCH and the PSCCH to the same orthogonal frequency division multiplexing (OFDM) symbol is made based on a number of subchannels and at least one sized thereof.

Abstract: An operating method of a terminal configured to perform vehicle-to-everything (V2X) communication in a wireless communication system, including signaling a maximum physical sidelink feedback channel (PSFCH) receiving capability to a base station; and receiving a wireless signal transmitted from the base station based on the maximum PSFCH receiving capability, wherein the maximum PSFCH receiving capability is a maximum number of PSFCHs receivable during one time transmission interval (TTI).

Abstract: A method of receiving a downlink control channel in a user equipment may include receiving, using two or more antenna ports, a shortened physical downlink control channel (PDCCH) transmitted using a space-frequency block code (SFBC), by using at least one shortened control channel element (SCCE) for shortened transmission time interval (STTI) transmission; and monitoring the shortened PDCCH. The at least one SCCE may include at least one shortened resource element group (REG) including a number of resource elements (REs), where the number is unequal to an integer multiple of the number of antenna ports allocated to the shortened PDCCH.
