Abstract: The present disclosure provides an uplink signal transmission method, a terminal, and base station. The terminal receives, from a base station, control information for an uplink scheduling, the control information including information indicating a reference starting position of a physical uplink shared channel (PUSCH); and transmits, to the base station, data based on the information indicating the reference starting position of the PUSCH. The information indicating the reference starting position of the PUSCH includes a starting symbol and a starting position preceding the starting symbol.

Abstract: The present disclosure provides an uplink transmission method, and a corresponding user equipment, base station and computer readable medium. A method for an uplink data transmission includes: determining a transmission occasion for an uplink transmission and a Hybrid Automatic Repeat Request, HARQ, process ID corresponding to the transmission occasion; determining an antenna port according to a correspondence between antenna ports and HARQ process IDs and/or a correspondence between antenna ports and transmission occasions; and transmitting, by the antenna port, uplink data corresponding to the HARQ process ID and a pilot signal corresponding to the uplink data. By establishing the correspondence between the antenna ports and the HARQ process IDs or the transmission occasion, the base station determines the antenna port when detecting the uplink transmission, so that the HARQ process ID corresponding to the uplink transmission may be determined.

Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The present disclosure discloses a method and an apparatus for data transmission. The method comprises: performing data transmission in a listen-before-talk mode; obtaining HARQ-ACK information of transmitted data bursts; and adjusting a contention window size CWS for carrier sensing to be performed before transmission of a next data burst based on HARQ-ACK information of reference data, wherein the reference data refers to a chosen PDSCH or PUSCH in a reference slot in a reference data burst selected from the transmitted data bursts. The method of the present disclosure may effectively reduce transmission collision between different nodes.

Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). A method for determining transmitting resources in vehicle to vehicle/pedestrian/infrastructure/network (V2X) communication is provided. The method includes determining, by a user equipment (UE), a set {ti} consisting of configurable V2X subframes within one system frame period, by the UE, determining information about a bitmap for configuring a resource pool, determining, in the set {ti}, subframes belonging to the resource pool, by the UE, selecting, after resource reselection, the position of a resource for initial transmission, determining, in the resource pool, the subframe position of the reserved resource according to a resource reservation subframe interval Prsv and the number of resource reservations, readjusting the position of the reserved resource when a certain condition is satisfied, and transmitting, by the UE, a physical sidelink shared channel (PSSCH) on the determined resource for initial transmission and the reserved resource.

Abstract: The present application provides a method for transmitting data, which includes the following. A UE detects a physical downlink control channel, PDCCH, on a configured control resource set; the UE analyzes the detected PDCCH, and determines a method for dividing code blocks, CBs, and a method for rate matching of a physical downlink shared channel, PDSCH, and receives the PDSCH accordingly. By the method of the present application, when a service with a low delay requirement punches the time-frequency resources of other services, a performance of the other services is improved as much as possible, and the resource utilization rate is improved as much as possible.

Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The present invention provides a method of a base station for supporting an inter-system handover from an evolved packet system (EPS) system to a 5th generation (5G) system. The present application provides a method for transmitting HARQ-ACK information, including steps of: detecting, by a UE, a PDCCH and receiving a PDSCH scheduled by the PDCCH; for one slot of one carrier, determining, according to a configured slot pattern and a configured PDCCH monitoring occasion, the HARQ-ACK occasion and the number of HARQ-ACK bits occupied by the one slot; and, generating, by the UE, an HARQ-ACK codebook according to the HARQ-ACK occasion and the number of HARQ-ACK bits occupied by the one slot, and transmitting HARQ-ACK information. By the method of the present invention, the number of HARQ-ACK bits to be fed back within each slot is reduced, and the feedback overhead is reduced; moreover, the number of bits of the generated HARQ-ACK codebook changes semi-statically, so that the confusion between a base station and a UE is avoided.
