Embodiment Construction

[0168] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0169] First, a brief introduction to the nouns involved in the embodiments of this application:

[0170] Low-power wide-area (Low-Power Wide-Area, LPWA) business is a business derived from the background of Internet of Things (Internet of Things, IoT) technology development. IoT technology enables a large number of sensing and control devices to connect to LTE base stations (eNB) or ...

Abstract

The invention provides a data sending method and device, a data receiving method and device, a terminal and a storage medium, and relates to the field of communication. The method comprises the following steps: acquiring a transmission parameter set; receiving downlink control information, wherein the downlink control information comprises an information field; determining a target repeated transmission frequency n according to the transmission parameter set and the information field, wherein n is a positive integer; and performing data transmission in a target transmission resource accordingto a target transmission mode and the target repeated transmission frequency n. In the method for acquiring the transmission parameter set and the information field in the downlink control informationand thus determining the repeated transmission frequency in an authorization-free scheduling terminal, the repeated transmission frequency is reasonable, the problem that the repeated transmission frequency of low-power-consumption wide area equipment is unreasonable due to the fact that the reasonable transmission frequency cannot be determined is avoided, and the data transmission success rateof the low-power-consumption wide area equipment is increased.

Description

technical field [0001] The present disclosure relates to the field of mobile communication, and in particular to a data sending and receiving method, device, terminal and storage medium. Background technique [0002] With the rapid development of the Internet of Things (Interet of Things, IoT), machine-type communications (machine-type communications, MTC) technology and narrow-band Internet of Things (Narrow-Band Internet of Things, NB-IoT) Low-Power Wide-Area (LPWA) services, such as remote copying of water meter data, regular collection of agricultural information, etc. [0003] Because the amount of data transmitted by the equipment in the low-rate service to the base station is small each time, if the traditional Long Term Evolution (LTE) data transmission process is adopted, it is easy to generate a large signaling overhead, so the uplink license-free is usually used A scheme for data transmission of low-power wide-area devices. At the same time, because low-power wi...
