Problems solved by technology

[0003] Although theoretical analysis and field tests show that the performance of the 5G system in outdoor scenarios is better than that of the 4G system, but in outdoor coverage indoor scenarios, the 5G system only has indoor uplink shallow coverage capabilities, and its uplink deep coverage performance is worse than that of the 4G system.
For example, the path loss of 3.5GHz frequency is 7~9dB higher than that of 1.8GHz frequency on average; the uplink coverage performance is 5.2dB worse than that of FDD when the 2.5ms double-period TDD frame structure is adopted.

Abstract

The invention relates to an uplink signal transmission method, device and system, and relates to the technical field of communication. The transmission method comprises the following steps: allocating corresponding transmitting antennas to a terminal on different communication resources, wherein the communication resources comprise at least one of a time resource and a frequency resource; and transmitting the distribution result of the transmitting antenna to the terminal by using a signaling corresponding to the transmitting diversity mode according to the currently adopted transmitting diversity mode, so that the terminal transmits an uplink signal by using the corresponding transmitting antenna.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular, to an uplink signal transmission method, an uplink signal transmission device, an uplink signal transmission system, and a non-volatile computer-readable storage medium. Background technique [0002] There are many differences between 5G systems and 4G systems. For example, 4G adopts 1.8GHz LTE (Long Term Evolution) FDD (Frequency Division Duplexing, frequency division duplexing) system, 5G adopts 3.5GHz NR (New Radio, new air interface) TDD (Time Division Duplexing, time division duplexing) system )system. [0003] Although theoretical analysis and field tests show that the performance of the 5G system in outdoor scenarios is better than that of the 4G system, in the outdoor coverage indoor scenario, the 5G system only has the capability of indoor uplink shallow coverage, and its uplink deep coverage performance is worse than that of the 4G system. For exam...
