Embodiment Construction

[0209] Before introducing the technical solutions of the embodiments of the present invention, the distributed architecture in the prior art is firstly introduced.

[0210] See figure 1 , is a schematic diagram of a distributed architecture. from figure 1 It can be seen from the figure that this distributed architecture consists of three devices, which are control device, switching device (optional) and access device. Then, if it is a tightly coupled type, the control device can be understood as a BBU, the switching device can be understood as an rHub, and the access device can be understood as a pRRU. If it is a loosely coupled type, the control device can be understood as a BBU, and the switching device can be understood as The switch and the access device can be understood as pRRU or RRU (Radio Remote Unit, remote radio unit). in:

[0211] Control equipment: including a processor, which includes RRC (Radio Resource Control, radio resource control), GTP (General Packet R...

Abstract

Disclosed is a radio frequency processing device for addressing a technical problem in which a large time delay between a baseband processing device and a radio frequency processing device causes a poor system performance. The device comprises: a storage for storing a set of code; and a processor for controlling the radio frequency processing device to process a baseband signal or a radio frequency signal when some or all of the set of code is executed, wherein the process includes modulating the baseband signal or demodulating the radio frequency signal, and processing MAC PDU or processing MAC PDU and RLC PDU. Also disclosed is a corresponding processing method.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a radio frequency processing device and a processing method. Background technique [0002] In the continuous networking of indoor small stations, if pRRU (pico Radio Remote Unit, micro radio frequency remote unit), rHub (Remote Hub, remote hub), and BBU (Building Base band Unit, indoor baseband processing unit) are deployed at the same time, then This deployment mode belongs to the tight coupling type, and the interface between the pRRU and the rHub is CPRI (Common Public Radio Interface, common public radio interface). In this deployment mode, the rHub is a dedicated device, the transmission delay between the pRRU and the BBU is small, and the overall performance is good. However, the pRRU and the rHub are usually connected by wires (network cables or optical fibers). During deployment, special design and installation of cable channels is usually required, and the deploy...
