Abstract: A data transmission method and a data transmission device for a TDD system are provided, so as to reduce the frequency hopping operations, reduce the retuning time, prolong a valid duration for the data transmission and reduce the time period for the data transmission, and reduce the power consumption. The data transmission method includes steps of: at a predetermined retuning start time point, adjusting, by a UE, a carrier frequency for data reception and transmission within a predetermined retuning duration so as to acquire the adjusted carrier frequency; and performing, by the UE, uplink data transmission and downlink data reception at the adjusted carrier frequency with a network device within a consecutive duration in accordance with a TDD uplink-downlink configuration. The consecutive duration is a duration from a current retuning end time point to a next retuning start time point.

Abstract: Disclosed by the present application are a resource mapping method and apparatus and device, comprising: determining to-be-sent data hosted on a data-channel physical downlink shared channel (PDSCH)/physical uplink shared channel (PUSCH); mapping said to-be-sent data to a virtual resource block (VRB); mapping the virtual resource block to a physical resource block (PRB) in resource block (RB) bundle units. Using the present application, it is possible to prevent the problem of the size of a virtual resource block bundle being inconsistent with the size of a physical resource block bundle, thus causing it to be impossible to map the virtual resource block to the physical resource block.

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.
