Problems solved by technology

[0004] In a large number of IoT devices, sometimes the amount of data communicated by each device is very small. If the data transmission method in the existing wireless cellular network is used to transmit the small data, the efficiency of the communication system will be low, and the signal of the communication process will be low. costly

Embodiment Construction

[0039] According to the current communication mode in the wireless cellular network, an uplink data transmission process includes: random access request, wireless resource allocation and connection establishment, data link layer connection establishment, identity provision, encryption start, data transmission, data Link connection release and wireless resource connection release; for the downlink data transmission process, in addition to including the same processing flow as the uplink data transmission process, it also includes a paging process before random access to the network. It can be seen that, in order to complete data transmission, a large amount of communication process signaling is required.

[0040] The wireless communication technology mentioned above can meet the needs of communication to a certain extent. However, in the future, there will be a demand for the Internet of Things formed by the simultaneous access of a large number of devices.

Abstract

The invention provides a data transmission method for a wireless cellular network, a base station, and a terminal. The wireless cellular network comprises two Internet of Things (IoT) communication shared channels with different frequencies, i.e., an uplink channel and a downlink channel. The method comprises the following steps: when data is to be sent to a base station side, monitoring whether the uplink channel is idle or not; when the uplink channel is idle, sending the data through the uplink channel in the form of an information frame, wherein the information frame comprises identity information of a terminal, and identification information of the information frame; and receiving a response data frame corresponding to the information frame through the downlink channel, and determining that data transmission is complete when the response data frame indicates that the information frame is correctly transmitted, wherein the response data frame comprises the identification information of the information frame. The method, the base station and the terminal adopting the technical scheme have the advantages that command expenses during communication can be reduced, and the efficiency of a communication system can be improved.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a data transmission method in a wireless cellular network, a terminal and a base station. Background technique [0002] According to the current communication mode in the wireless cellular network, an uplink data transmission process includes: random access request, wireless resource allocation and connection establishment, data link layer connection establishment, identity provision, encryption start, data transmission, data Link connection release and wireless resource connection release; for the downlink data transmission process, in addition to including the same processing flow as the uplink data transmission process, it also includes a paging process before random access to the network. Therefore, it can be seen that in order to complete the data transmission, a large amount of communication process signaling is required. [0003] The wireless communication technology...
