Method, apparatus, and system for data transmission

摘要

The present invention provides a method, an apparatus and a system for data transmission. 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.

主权项

1. A data transmission method, comprising:
obtaining, by a remote radio unit, first microwave data information generated through format conversion and adaptation processing performed on a microwave signal received by a microwave outdoor unit through a microwave antenna; and performing, by the remote radio unit, time division multiplexing through a preset rule on the first microwave data information and processed first radio frequency data information to generate multiplexed information wherein, the processed first radio frequency data information is generated through processing a radio frequency signal received by a base station antenna, sending, by the remote radio unit, the multiplexed information to a baseband unit, for sending the first microwave data information or processed first microwave data information to a microwave indoor unit, wherein, the processed first microwave data information, into which the baseband unit processes the first microwave data information, comprises first valid data information and first control information.
