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 application relates to the technical field of communications and discloses a communication method and apparatus for improving the usage efficiency of a wireless channel. The method includes the steps of when a first terminal wants to send first data to a base station, sending a channel request frame to the base station, the channel request frame carrying a first time length of a channel that the first terminal requests to occupy, the first time length being greater than a time length required for sending the first data by the first terminal, and the first data having a degree of sensitivity to the delay being greater than a preset threshold; receiving, by the first terminal, a channel response frame returned for the channel request frame by the base station; aggregating, by the first terminal, the first data with second data to generate aggregated data, the second data being sent by at least one second terminal to the first terminal; and sending, by the first terminal, 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...
