Abstract

A radio frequency signal transceiving method and device thereof are proposed. The method is configured for a radio equipment controller (REC) of a radio frequency signal transceiving device to exchange radio signals between a plurality of Baseband Units (BBUs) and a plurality of Radio Equipments (REs) that respectively connected to a plurality of Remote Radio Units (RRUs), and the method includes but not limited to the step of: receiving a first radio downlink signal at least, generating a first downlink control signal, modulating the first radio downlink signal at least into a first analog downlink signal at a first frequency according to the first downlink control signal, multiplexing the first analog downlink signal and the first downlink control signal into an integrated analog downlink signal, converting the integrated analog downlink signal into an optical downlink signal, and transmitting the optical downlink signal.

Description

technical field [0001] The invention relates to a radio frequency signal transceiving device and its method, as well as a self-monitoring optical transmission device and its method. Background technique [0002] For example, radio interfaces such as Common Public Radio Interface (Common Public Radio Interface, CPRI) or Open Base Station Standard Initiative (Open Base Station Standard Initiative, OBSAI) connect a radio equipment control device (radio equipment control, REC) in a wireless base station with radio equipment ( Standardization of the protocol interface between radio equipment (RE), which allows the baseband unit (Baseband Unit, BBU) of the base station and the remote radio unit (Remote Radio Unit, RRU) to be separated, so that the system capability and flexibility can be improved accordingly. However, one of the main disadvantages of these protocols is bandwidth efficiency. For example, CPRI consumes more than 9 GHz of bandwidth to transmit / receive 24 channels of...
