Embodiment Construction

[0045] In order to facilitate understanding of the technical solutions of the embodiments of the present application, a brief introduction of related technologies of the present application is given as follows.

[0046] First, IoT:

[0047] IoT is the "Internet of Things Connected". It expands the user end of the Internet to any item and item, enabling information exchange and communication between any item and item. Such a communication manner is also called machine type communications (MTC). Wherein, the communicating nodes are referred to as MTC terminals or MTC devices. Typical IoT applications include various aspects such as smart grid, smart agriculture, smart transportation, smart home, and environmental detection.

[0048] Since the Internet of Things needs to be applied in a variety of scenarios, such as from outdoors to indoors, from the ground to the ground, many special requirements are put forward for the design of the Internet of Things. For example, because ...

Abstract

The embodiment of the invention provides a data receiving and sending method, device and system, which can improve the scheduling flexibility of a network device during data transmission. The method comprises that: a terminal device receives indication information from a network device, wherein the indication information indicates a first resource for transmitting uplink data and the first resource overlaps a data early transmission (EDT) physical random access channel resource, and under the condition that the terminal device determines that the preset condition is met, delaying sending of the uplink data to the network equipment in a second resource which is not overlapped with the resource of the EDT physical random access channel.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to methods, devices and systems for receiving and sending data. Background technique [0002] With the development of Internet of Things (IoT) technology, IoT applications have higher and higher requirements for IoT design. In order to meet these demands, the 3rd generation partnership project (3GPP) of the mobile communication standardization organization approved a new research topic at the #62 plenary session of the radio access network (RAN) to study the The method of supporting extremely low-complexity and low-cost Internet of Things in the network, and was established as a narrowband Internet of things (narrow band internet of things, NB-IoT) project at the RAN#69 meeting. [0003] At present, in the NB-IoT system, an early data transmission (EDT) feature has been introduced. The EDT feature is an optional feature for terminal devices in the NB-IoT system...
