Data transmission method and device for uplink short-latency communication

Abstract

The present invention provides a data transmission method and device for uplink short-latency communication. The method includes: a user equipment detects whether the data to be sent is short-latency communication data; if the user equipment detects that the data to be sent is short-latency For the communication data, the short-latency communication data is sent to the base station on the short-latency dedicated transmission resource according to the pre-acquired transmission format, and the short-latency dedicated transmission resource is used to transmit the short-latency communication data.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a data transmission method and device for uplink short-latency communication. Background technique [0002] The Internet of Things (Machine to Machine; abbreviation: M2M) is to connect all items with the Internet through information sensing devices to realize intelligent identification and management. Specifically, the combination of the Internet of Things and the Internet can realize the remote perception and control of all items, thereby creating a generative life system. Compared with the current Internet, it is larger and widely used in smart grid, smart transportation, environmental protection, government work, public safety, smart home, smart fire protection, industrial testing, elderly care, personal health and other fields. [0003] At present, in some IoT application scenarios, the delay requirements are extremely strict. For example, in some commu...

Problems solved by technology

However, since the current cellular communication system is mainly designed for human-to-human communication (Human to Human; H2H for short), for example, taking the Long Term Evolution (Long Term Evolution; LTE for short) system as an example, When a user equipment (UserEquipment; UE for short) in an idle (Idle) state needs to send new uplink data, it first needs to establish a connection with the network, change the Idle state to a Connect (Connect) state, and then transmit data , and this process has a long delay, generally more than 50 milliseconds (ms), so it is difficult to meet the short delay requirements of M2M communication

At the same time, in some delay-sensitive communication requirements of the smart grid, the amount of data is generally small, and the normal communication method will cause a large amount of additional signaling interaction, which is inefficient and may even cause signaling congestion.
