Abstract: A semiconductor package includes a lower connection structure, a semiconductor chip on the lower connection structure, an upper connection structure including a first conductive pattern layer on the semiconductor chip, a first insulating layer on the first conductive pattern layer, a second conductive pattern layer on the first insulating layer, a first via penetrating the first insulating layer to extend between the first conductive pattern layer and the second conductive pattern layer, and a second insulating layer extending between a side surface of the first via and the first insulating layer, and an intermediate connection structure between the lower connection structure and the upper connection structure. A chemical composition of the first insulating layer may differ from a chemical composition of the second insulating layer.

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: 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.
