Uplink Data Transmission Confirmation Apparatus, Device, and Method

摘要

The present disclosure provides an uplink data transmission confirmation apparatus, device, and method. The apparatus includes the following. A transceiver module, configured to send uplink data to a base station; a detection module, configured to detect, within a first preset period, whether first physical downlink control channel signaling sent by the base station is received, and obtain a detection result; and a judging module, configured to determine, according to the detection result, whether the uplink data is successfully transmitted. According to the apparatus provided in embodiments of the present disclosure, physical downlink control channel signaling is reduced in a process of confirming, by the terminal in a coverage enhancement scenario, whether the uplink data is successfully transmitted; and whether an Msg3 is successfully transmitted can be confirmed.
