    Abstract: A data transmission method and a communications apparatus are described that reduce complexity and overhead of data reception performed by a base station. The method includes receiving information about a repetition quantity R1 corresponding to Tmax, where Tmax is a maximum transport block size allowed to be used to transmit data. The method further includes determining a cyclic parameter L based on R1, where the cyclic parameter L indicates that content carried in each of a plurality of time units to which a transport block used to transmit the data is mapped is repeated in L consecutive time units, and wherein a size of the transport block actually used to transmit the data is Ts, and Ts is less than a maximum transport block size (Tmax). The method further includes transmitting the data based on the cyclic parameter L.

    Abstract: An information indication method is provided, including: A terminal-side device receives first higher layer signaling from a network-side device, where the first higher layer signaling is used to configure N bandwidth parts BWPs, and N is a positive integer. The terminal-side device receives downlink control information from the network-side device, where the downlink control information includes an indication field. When N is less than a maximum quantity of BWPs that can be configured through the first higher layer signaling when the terminal-side device is in a connected mode (for example, an RRC connected mode) or a maximum quantity of BWPs that can be determined by using candidate bit states of the indication field that is used to determine an active BWP and that is in the downlink control information, the indication field indicates a position of the active BWP located in an initial BWP and the N BWPs.

    Abstract: A data transmission method in the present application includes: determining, by first UE, a frame structure in a time unit, where the frame structure indicates that N type-1 OFDM symbols and a GP are included in the time unit, and a subcarrier spacing of each type-1 OFDM symbol is Δf1. Therefore, according to the data transmission method and the user equipment in embodiments of the present application, a frame structure in a time unit is determined. The frame structure indicates that N type-1 OFDM symbols and a GP are included in the time unit, and a subcarrier spacing of each type-1 OFDM symbol is Δf1. Therefore, when an NB-IOT system is deployed in an LTE system in an embedded manner, and when NB-IOT UE is sending data, a channel resource of the legacy LTE system can be adequately utilized, and a conflict with a legacy LTE SRS can be avoided.
