Abstract: Embodiment of the present application provides a transmission method, a terminal device, and a base station, used to solve the technical problem in the related art that there is no method supporting CBG-based retransmission and ACK/NACK feedback. The transmission method comprises: receiving by the terminal device a downlink control channel; and acquiring by the terminal device a first indication field from the downlink control channel, the first indication field being used to indicate whether each code block group (CBG) in the corresponding CBGs in an initial transmission of TB needs to be retransmitted.

Abstract: A method for determining and configuring a resource used for transmitting downlink data, a terminal and a base station: the base station configures, for each terminal, resource collections or resource collection subgroups used for receiving downlink data, and then the base station notifies the terminal, by means of an explicit signaling, whether all of the resource collections or each resource collection of the configured resource collections are available, or whether all of resource collection subgroups or each resource collection subgroup of the resource collection subgroups are available, thus allowing the terminal to determine, according to the notification, the time-frequency resource position of a resource used to receive downlink data, so that the terminal may carry out rate matching on the determined resource.

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 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.
