Embodiment Construction

[0032] In this embodiment, the system block diagram of the large-scale access method integrating computing and communication is as follows: figure 1 As shown, the base station has N antennas, and each mobile terminal is configured with M antennas. Each mobile terminal separately designs a communication transmission beam and a calculation transmission beam for its communication signal and calculation signal, and then superimposes and encodes the communication signal and calculation signal after beamforming, and transmits the signal to the base station at the same time. After the base station receives the signal, the communication receiver is designed to decode the communication signal and calculate the receiver to recover the target calculation function.

[0033] The specific technical solutions adopted in this embodiment are as follows:

[0034] The large-scale access method integrating computing and communication includes the following steps:

[0035] 1) A base station with N ante...

Abstract

The invention discloses a large-scale access method integrating calculation and communication. A multi-antenna base station is arranged in the center of a cell, and a large number of mobile terminalsare accessed to a wireless network through the base station. The mobile terminal performs beam forming on the communication signal and the calculation signal to be transmitted respectively, and then transmits the communication signal and the calculation signal after superposition coding. On one hand, the base station can directly receive the summation function obtained through air calculation by utilizing the superposition characteristic of the wireless channel, and then recover the target function through calculating the receiver. And on the other hand, the base station decodes the communication signal of each mobile terminal through the communication receiver. The invention provides an effective calculation and communication fusion large-scale access method for the Internet of Things with a large-scale mobile terminal.

Description

Technical field [0001] The invention relates to the field of wireless communication, in particular to a large-scale access method integrating computing and communication. Background technique [0002] In recent years, with the rapid development of the Internet of Things and the continuous upgrade of smart devices, the trend of Internet of Everything has become more and more obvious, and the number of mobile access users is showing explosive growth. According to Cisco's latest forecast report, global mobile data traffic in 2020 will be 8 times that of 2015, and the number of connected mobile devices will exceed 25 billion. [0003] Currently, 5G networks are facing new challenges with explosive data traffic growth and massive device connections. At the same time, the new business scenarios of 5G networks, such as driverless cars, smart grids, industrial communications, etc., also put forward higher requirements for indicators such as latency, energy efficiency, device connections, ...
