Embodiment 1

[0041] The base station sends the first time-frequency resource set allocation information and the first sending mode description information to the terminal A, where the first sending mode includes at least one of the following: demodulation reference signal position. Preferably, the modulation and coding method of the first data packet, the number of transmission layers of the first data packet, and the first data packet are composed of T bits obtained by channel coding B useful bits, which can refer to 4G or 5G mobile communication The channel coding method of the system.

[0042] The base station allocates the second set of time-frequency resources to the terminal B, where, for example, Figure 2-Figure 4 As shown, there is overlap between the second time-frequency resource set and the first time-frequency resource set (the overlapping part is called an overlapping resource set), and the resources contained in the first time-frequency resource set in the frequency domain a...

Abstract

The present invention provides a method for solving data transmission conflicts in the Internet of Things. The present invention includes: the base station sends the allocation information of the first time-frequency resource set and the description information of the first sending mode to the first terminal; allocates the second time-frequency resource set to the first terminal; For the second terminal, the first time-frequency resource set includes an overlapping resource set that overlaps with the second time-frequency resource set and a non-empty third time-frequency resource set; the base station uses resources in the third time-frequency resource set to The time continuity determines the second transmission mode of the first data packet; the base station sends the description information of the overlapping resource set to the first terminal; the first terminal determines the second transmission method of the first data packet according to the description information In this way, the first data packet is received; if the reception is unsuccessful, feedback information is sent to the base station; the base station uses the fifth time-frequency resource set to send part of the first data packet to the first terminal. The invention overcomes the data transmission conflict problem in the existing machine communication.

Description

technical field [0001] The invention relates to a data transmission method, in particular to a method for solving data transmission conflicts in the Internet of Things. Background technique [0002] 5G will meet the diverse business needs of people in various areas such as living, working, leisure, and transportation, even in dense residential areas, offices, stadiums, open-air gatherings, subways, expressways, high-speed rails, and wide-area coverage. It can also provide users with extreme business experiences such as ultra-high-definition video, virtual reality, augmented reality, cloud desktop, and online games.
