Abstract: Disclosed are a data transmission method, a terminal, and a base station. Determined is that a TB needs to be divided into M CBG; grouping, according to a preset grouping scheme, multiple CB produced when the one TB is code block segmented, thus diving the one TB into the M CBG; and transmitting data according to the M CBG, where M is a positive integer. The technical solution of the present invention solves the technical problem of low data transmission efficiency and low resource utilization rate in an LTE system found in the prior art.

Abstract: The present application discloses methods and devices for determining a downlink resource set and sending resource position information, and particularly relates to a method for determining, by a terminal, a downlink control channel resource set, a method for sending, by a base station, a position related to a downlink control channel resource set, and related devices. A terminal obtains, in a predefined manner and/or by receiving a notification of a base station, a frequency domain position and a time domain position of a downlink control channel resource set corresponding to the terminal, so as to determine that the downlink control channel resource set corresponding to the terminal is a third downlink control channel resource set. The base station transmits a common downlink control channel and/or a terminal-dedicated downlink control channel on the frequency domain and time domain positions of the downlink control channel resource set determined by the terminal.

Abstract: The present application discloses an uplink data retransmission method and terminal. The method comprises: a terminal determining whether to spontaneously retransmit first uplink data; and if the terminal determines to spontaneously retransmit the first uplink data, the terminal retransmitting the first uplink data on a physical resource that is pre-configured on a network side. The application adopts the above technical solution to resolve the technical problem in which, for a URLLC service, if a retransmission mechanism is based on a conventional HARQ mechanism, a certain time interval is required between two adjacent transmissions of uplink data, which may result in retransmission being unsupported for a certain time delay requirement and configuration, and as a result a reliability requirement for the URLLC service cannot be met.

Abstract: Disclosed are a data transmission method, device, and system. The method comprises: for the transmission of random access uplink data, according to the correspondence between preambles and data resources as described by a protocol, determining the data resource corresponding to the preamble in the uplink data transmission, different preambles corresponding to different data resources; transmitting the preamble and the uplink data that uses the determined data resource. In the embodiments of the present invention, a protocol describes the correspondence between preambles and data resources. For the transmission of random access uplink data, the data resource corresponding to the preamble in the uplink data transmission can be determined, and different preambles correspond to different data resources. Thus it can be ensured that different users use different data resources to bear uplink data, thereby enabling the data portion multiplexing for multiple users.

Abstract: Disclosed in the present application are a data transmission method and device. The method comprises: a base station sends a signaling notification to a terminal, so that the terminal determines, according to the signaling notification, whether a pilot signal of data transmitted using a second transmission time interval exists within a first transmission time interval, wherein the first transmission time interval is shorter than the second transmission time interval, or the priority of a service carried by the first transmission time interval is higher than the priority of a service carried by the second transmission time interval, there is a resource overlap between the first transmission time interval and the second transmission time interval, and the terminal using the first transmission time interval for data transmission knows a pilot signal location of the data transmitted using the second transmission time interval; and the base station performing transmission according to a pilot signal resource location of the second transmission time interval. The present application can ensure that a receiving end for other service transmissions can use a pilot signal for data demodulation, thereby avoiding the waste of resources caused by the destruction of the pilot signal.
