AI Technical Summary

Problems solved by technology

[0008] Since a new RTT or TTI with a shorter length is added, and in the prior art, there is no communication mechanism to distinguish between two RTT or TTI lengths, therefore, conflicts are likely to occur

Embodiment Construction

[0288] seefigure 1 , an embodiment of the data transmission method in the embodiment of the present invention includes:

[0289] 101. The user equipment receives the control message sent by the base station;

[0290] The user equipment receives the control message sent by the base station, specifically, the control message is used to determine the RTT length corresponding to the data transmitted between the user equipment and the base station and perform the data transmission by the base station.

[0291] In a specific application, the control message may include a control message sent through high-layer signaling, such as a radio resource control (RRC, Radio Resource Control) configuration message; it may also include a control message sent through physical layer signaling, such as a downlink control Information (DCI, Downlink Control Information) message; Exemplarily, the high-level signaling includes: dedicated signaling and broadcast messages.

[0292] Specifically, the R...

Abstract

Embodiments of the present invention disclose a data transmission method, user equipment and a base station, which are used to solve the conflict problem in the data transmission process when scenarios with different processing delays coexist. The method of the embodiment of the present invention includes: the user equipment receives a control message sent by the base station, the control message is used to determine the RTT length corresponding to the data transmitted between the user equipment and the base station; the user equipment responds to the control message according to the control message. The message determines the round-trip transmission time RTT length corresponding to the data transmitted between the base stations; the user equipment transmits the data with the base station according to the RTT length.

Description

technical field [0001] The present invention relates to the communication field, in particular to a data transmission method, user equipment and a base station. Background technique [0002] In the future 5G (fifth generation communication) technology, with the continuous expansion of air interface technology and applications, reducing latency has become one of the key performance indicators. For example, the end-to-end delay requirement of Real-time remote computing for mobile terminals (real-time remote monitoring of mobile terminals) is less than 10ms, the delay requirement of Traffic efficiency and safety (efficient and safe service) is 5ms, and the current long-term evolution (LTE, The transmission time interval (TTI, transmission time interval) of Long Term Evolution) is 1ms, and the round-trip transmission time (RTT, Round-Trip Time) is 8ms, that is, a retransmission will bring a delay of 8ms, and the uplink transmission The time required is shown in the table below:...
