  • Publication number: 20180324822
    Abstract: Embodiments of the present application propose a feedback method for an uplink channel, and an apparatus. In the solution, instead of always sending a first common message or a first scheduling command in any case, a base station determines, only after determining whether a data packet to be sent by a terminal is the last data packet of the terminal, whether a to-be-sent message including an indication bit that is used to indicate whether the base station correctly receives the data packet sent by the terminal is the first scheduling command or the first common message. Alternatively, when the base station determines that the terminal needs to send a next data packet or needs to retransmit the data packet, an indication bit for the terminal in at least two indication bits is used to indicate uplink control information. Therefore, this avoids a waste of resources.

  • Publication number: 20180316532
    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 ?f1. 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 ?f1.
