Embodiment Construction

[0051] The embodiment of the present application provides a signal processing method and related equipment. The baseband processing device sends a downlink analog baseband signal to the radio frequency device, so the radio frequency device no longer needs to be equipped with a digital-to-analog converter, which reduces the complexity of the radio frequency device. , power consumption and heat production.

[0052] Embodiments of the present application are described below in conjunction with the accompanying drawings. Those of ordinary skill in the art know that, with the development of technology and the emergence of new scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0053] The terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned accompanying drawings are used to distinguish similar objects, and are not necessarily used to ...

Abstract

The embodiment of the present application discloses a signal processing method and related equipment. The signal processing method can be used in the field of signal transmission between the baseband processing device and the radio frequency device of the access network equipment. The baseband processing device obtains at least two first downlink The digital baseband signal is multiplexed into a second downlink digital baseband signal, and after the second downlink digital baseband signal is converted into the first downlink analog baseband signal, it is sent to the radio frequency device, and the radio frequency device performs the first downlink analog baseband signal Demultiplexing, and generating a downlink radio frequency signal to be sent to the terminal device according to at least two second downlink analog baseband signals obtained through the demultiplexing operation. Therefore, there is no need to configure a digital-to-analog converter on the radio frequency device, which reduces the complexity, power consumption and heat generation of the radio frequency device.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a signal processing method and related equipment. Background technique [0002] A cellular communication system is a widely used wireless communication system. In a cellular communication system, a base station provides a radio access (radio access) service for terminal equipment (also referred to as "user equipment"). Remote radio is a communication method commonly used by current base stations, that is, the baseband part and the mid-radio frequency part of the base station are respectively located in two separate devices, wherein the baseband part can be located in the baseband unit (BBU), and the mid-radio frequency part It may be located in a remote radio unit (remote radio unit, RRU). [0003] In the prior art, a common public radio interface (CPRI) protocol is often used between the BBU and the RRU to transmit digital baseband signals in the downlink ...
