Wireless data transmission method, network side device, user equipment, and system

A wireless data transmission method, comprising:

• sending, by user equipment to a network side device, a repetition quantity required for data transmission;
• obtaining, by the user equipment, a round trip time (RTT) of the user equipment in a hybrid automatic repeat request (HARQ), wherein the RTT is determined by the network side device according to obtained repetition quantity information of the user equipment, process quantity information of the user equipment, and a transmission time interval (TTI);
• and
• transmitting, by the user equipment, data to the network side device in the RTT according to the repetition quantity.

User equipment, comprising:

• a transmitter, configured to send, a repetition quantity required for data transmission to a network side device;
• and
• a processor, configured to obtain a round trip time (RTT) of the user equipment in a hybrid automatic repeat request (HARQ), wherein the RTT is determined by the network side device according to obtained repetition quantity information of the user equipment, process quantity information of the user equipment, and a transmission time interval (TTI);
• wherein the transmitter is further configured to transmit data to the network side device in the RRT according to the repetition quantity.
