Abstract

The invention provides a data transmitting method and related equipment. The data transmitting method comprises the following steps that: when a base station supports various wireless protocols, radio equipment RE in the base station determines wireless protocols two ports of the RE respectively belong to; and the two ports are utilized to respectively transmit data of the corresponding wireless protocols. By using the technical scheme provided by the embodiment of the invention, the base station can support various wireless protocols and service data and control data of various protocols can be normally transmitted.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a data transmission method and related equipment. Background technique [0002] The CPRI (Common Public Radio Interface) specification is an interface specification between REC (Radio Equipment Control, wireless equipment controller) and RE (Radio Equipment, wireless equipment) inside the wireless base station. CPRI includes three planes: user data plane, management control plane, and synchronization control plane. According to the protocol, there are three layers: physical layer (Layer1, L1), link layer (Layer2, L2) and application layer (Layer3, L3). In order for the REC to know the topology information of the CPRI link (including the head and tail information of the CPRI link, RE location information, etc.), the REC transmits service data (such as: IQ data) and control data (such as: HDLC ( High-level Data Link Control, advanced data link control) data), and perform TOP...
