Embodiment Construction

[0094] In order to make the purpose, technical solution and advantages of the application clearer, the application will be further described in detail below in conjunction with the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0095] The embodiment of the present application is applied to the application scenario where a large number of low-power terminals access the wireless channel, but is not limited to the application scenario of the cellular mobile communication network MTC. Preferably, the terminal involved in this application can be an MTC device .

[0096] Such as figure 1 As shown, multiple terminals can communicate with the base station. For convenience of description, only five t...

Abstract

The present application relates to the technical field of communication, and discloses a communication method and device, which are used to improve the use efficiency of wireless channels. The method is as follows: when the first terminal intends to send the first data to the base station, it sends a channel request frame to the base station, the channel request frame carries the first time length for which the first terminal requests to occupy the channel, and the first terminal requests to occupy the channel. A time length is greater than the time length required by the first terminal to send the first data, and the sensitivity of the first data to time delay is greater than a preset threshold; the first terminal receives the A channel response frame returned by a request frame; the first terminal aggregates the first data and second data to generate aggregated data, and the second data is sent by at least one second terminal to the first terminal; the The first terminal sends the aggregated data to the base station.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a communication method and device. Background technique [0002] With the wide application of the Internet of Things (English: Internet of Things, abbreviation: IoT), machine type communication (English: Machine Type Communication, abbreviation: MTC), smart cities and vertically integrated industries, "low-power giant connection" has become the next generation One of the key application scenarios of the mobile communication network, the so-called "low-power giant connection" refers to a huge amount of low-power terminal application wireless channels. At present, the cellular mobile communication network that has provided services for billions of human mobile phone users still needs to add more than tens of billions of MTC devices. [0003] In the application scenario where a large number of terminals with low power consumption use wireless channels, if a larg...
