Abstract

The invention provides an air interface signal alignment processing method, device, equipment and a storage medium. The method comprises the following steps: a baseband unit receiving a processing delay amount and a first maximum delay compensation amount of a radio frequency unit reported by the radio frequency unit; the baseband unit determining a target delay compensation amount according to the processing delay amount; and the baseband unit being combined with the radio frequency unit to carry out delay compensation processing according to the target delay compensation amount and the firstmaximum delay compensation amount. Therefore, the baseband unit can share with the radio frequency unit for delay compensation, resource occupation of the radio frequency unit buffer is reduced, andthe buffer pressure of the radio frequency unit is reduced.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a processing method, device, device and storage medium for air interface signal alignment. Background technique [0002] In the composition of the wireless base station, the baseband unit and the radio frequency unit are two independent network elements, and the two communicate through the optical fiber connection, and the radio frequency unit can be extended to any network coverage area through the optical fiber. When realizing the optical fiber remote function of the video unit, it is necessary to ensure that the signals transmitted to the air interface (air interface) by all base stations in the entire network are synchronized, which requires that the signal transmitted by the radio frequency unit to the air interface can be transmitted at any distance by optical fiber. Arrive at the same moment. For the baseband unit, on its input side, all user signals ...
