Abstract

The invention discloses an asynchronous uplink transmission method, a terminal and a network device. The method includes: constructing uplink data to be transmitted according to a preset data structure; and sending the uplink data to the network device. The preset data structure includes: a preamble cyclic prefix, a preamble, at least one data part consisting of a data cyclic prefix and data, and a guard interval. In the embodiments of the present invention, by constructing uplink data with a preset data structure, when a terminal transmits small data packets in an idle state or an inactive state, it directly performs asynchronous uplink transmission through the preset data structure, which can save power consumption and signaling overhead. , and adopting the uplink data of the preset data structure can reduce the configuration complexity of the network equipment and the complexity of the terminal. In addition, inter-data interference can also be eliminated through guard intervals between different uplink data.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an asynchronous uplink transmission method, a terminal and a network device. Background technique [0002] Compared with previous mobile communication systems, the fifth generation (5Generation, 5G) mobile communication system, or New Radio (New Radio, NR) system, needs to adapt to more diverse scenarios and business requirements. The main scenarios of NR include enhanced Mobile Broadband (eMBB) communication, massive MachineType Communications (mMTC), ultra-reliable and ultra-low latency communication (Ultra-Reliable and Low Latency Communications, URLLC), these scenarios High reliability, low latency, large bandwidth, and wide coverage are required for the system. [0003] In mMTC or eMBB scenarios, the terminal needs to support low-power operation. In a traditional uplink transmission mode, if a terminal needs to send uplink data, it first needs to obtain upli...
