Abstract: Provided are a method and an apparatus for transmitting uplink data in a wireless communication system. Specifically, a first terminal transmits a random access preamble for requesting a connectionless transmission. The first terminal receives a random access response comprising scheduling information of the uplink data. The first terminal transmits the uplink data, a reference signal selected by the terminal and terminal identification information of the terminal from a first overlapping resource utilized by a second terminal. The first terminal receives, as a response for the uplink data, a response signal comprising a terminal identification information field containing terminal identification information corresponding to each reference signal.

Abstract: Provided are a method and a device for setting a space division connection between terminals for V2X communication in a wireless communication system. Specifically, a second terminal requests a connection setting with a first terminal from a base station. The second terminal measures a signal of the first terminal and generates a first beam group pair comprising a transmission beam group of the first terminal, which has a large signal size, and a reception beam group of the second terminal. When the second terminal receives a signal of a third terminal by using the reception beam group of the second terminal, the second terminal measures a signal of the third terminal and generates a second beam group pair comprising a transmission beam group of the third terminal, which has a large signal size, and the reception beam group of the second terminal.

Abstract: According to the present invention, a first physical downlink control channel (PDCCH) and a second PDCCH can be transmitted to user equipment. A first physical downlink data channel (PDSCH) corresponding to the first PDCCH, and a second PDSCH corresponding to the second PDCCH can be transmitted to the user equipment. When the first PDSCH has a lower decoding priority than the second PDSCH, and the decoding timing of the first PDSCH and the decoding timing of the second PDSCH overlap, the user device may decode the second PDSCH and not the first PDSCH at the decoding timing, and transmit information with respect to the first PDSCH as first ACK/NACK information. As a reply to the first ACK/NACK information, a third PDCCH not having a corresponding PDSCH may be transmitted to the user equipment.

Abstract: Disclosed is a method for performing contention-based transmission by a user equipment in a wireless communication system. Specifically, the method comprises the steps of: calculating a channel congestion for contention-based transmission within a predetermined time window; and performing contention-based transmission to an eNode B, using an allocated resource on the basis of the calculated channel congestion, wherein: the channel congestion is a ratio of a size of resources used for contention-based transmission at a unit time point to a size of a resource pool for the contention-based transmission at the relevant unit time point, and is calculated at every unit time point within the time window; and the size of the resource pool is independently configured at every unit time point.

Abstract: A method for transmitting a multiplexed uplink control channel and localized sounding reference symbol (localized SRS) by a terminal comprises a step of dividing the uplink control channel into a plurality of uplink control channel sub-blocks in a frequency domain and then transmitting the divided uplink control channel, when a frequency bandwidth of the localized SRS is smaller than or equal to a coherent bandwidth, wherein the divided uplink control channel sub-blocks may be frequency-division-multiplexed together with at least one localized SRS and then transmitted in one symbol.

Abstract: A method and apparatus for performing a scheduling request for transmitting uplink data in a wireless communication system are provided. Specifically, a terminal receives allocation information for a first SR resource that is semi-statically allocated from a base station. The terminal receives allocation information for a second SR resource dynamically allocated from the base station. The second SR resource is additionally allocated in addition to the first SR resource for a buffer status report (BSR). At this time, the allocation information for the first SR resource comprises: mapping information between the first and second SR resources and buffer size information. The terminal transmits an SR to the base station through the first SR resource or the second SR resource.

Abstract: Disclosed are a method for dividing a transport block of a low density parity check (LDPC) code and an apparatus therefor. A method for dividing a transport block of an LDPC code according to the present disclosure can improve the performance of the LDPC code by dividing the transport block using a minimum number of code blocks. In addition, it is possible to minimize shortening bits by making the size of some of the code blocks smaller than the size of the other code blocks. Further, it is possible to prevent performance degradation due to a minimum size code block by minimizing the number of the code blocks and performing shortening on a large size code block.

Abstract: A quasi-cyclic low density parity check (QC LDPC) code rate matching method is disclosed. According to the rate matching method in the present disclosure, the minimum lifting value can be selected from among lifting values by which a codeword longer than a target code block can be generated. A coding gain through retransmission can be acquired by generating the codeword that is longer than the target code block. In addition, by selecting a lifting value of a proper magnitude, rate matching for information bit sequences of various lengths can be performed.
