Abstract: 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.

Abstract: In one embodiment, an apparatus includes a memory comprising instructions and a processor in communications with the memory. The processor is configured to execute the instructions to determine a reference signal received power of user equipment (UE). In response to determining that the reference signal received power is less than or equal to a threshold, it is determined that the UE supports sending a physical random access channel, receiving a random access response message, sending a random access response acknowledgment message, and receiving a contention resolution message. In response to determining that the reference signal received power is above the threshold, it is determined that the UE supports sending the physical random access channel, and receiving the contention resolution message, and it is determined that the UE does not support sending the random access response acknowledgment message and receiving the random access response message.
