Abstract: A method, an apparatus and a system for data transmission are provided. The method includes: receiving processed first microwave data information that is received through a microwave antenna; performing multiplexing through a preset rule on the first microwave data information and processed first radio frequency data information that is received through a base station antenna, and sending multiplexed information to a baseband unit, so that the baseband unit sends the first microwave data information to a microwave indoor unit. In the method, the apparatus and the system for data transmission, microwave data information and radio frequency data information are multiplexed, and then multiplexed information is transmitted together. The microwave data information can be transmitted through a transmission medium between base station devices, such as a fiber, thereby saving connection cables between microwave transmission devices and reducing a device cost and an installation cost of the microwave transmission devices.

Abstract: The terminal device can generate a monophonic signal of a specified frequency, and can transmit the monophonic signal by using a specified receive antenna or transmit antenna of the terminal device. The terminal device has a function of transmitting the monophonic signal of the designated frequency by using any specified antenna. Therefore, a measurement system for an antenna complex number pattern of the terminal device can accurately measure a complex number pattern of each antenna of the terminal device in a manner in which the terminal device transmits the monophonic signal of the specified frequency by using each receive antenna or transmit antenna. The measurement system can further obtain an accurate measurement result when a MIMO OTA performance test is performed on the terminal device according to the complex number patterns of all the antennas of the terminal device.
