Problems solved by technology

However, at present, due to the internal circuit of the antenna of the sector splitting technology, for example, the circuit design of the 6-sector 1T2R is different from that of the 4T4R antenna circuit of the LTE system, which makes the two platforms incompatible

Embodiment Construction

[0051] Before explaining the technical solutions of the embodiments of the present application, the technical terms, technical scenarios and network element devices involved in the present application are firstly introduced.

[0052] 1. Baseband

[0053] Baseband, the inherent frequency band (frequency bandwidth) of the original electrical signal sent by the source (information source, also known as the transmitter) without modulation (spectrum shifting and conversion), is called the basic frequency band, or baseband for short. Among them, the baseband corresponds to the frequency band, and the frequency band refers to the frequency bandwidth occupied by the baseband signal after modulation, that is, the difference between the lowest frequency and the highest frequency occupied by a signal.

[0054] 2. Baseband signal

[0055] Baseband signal, the original electrical signal sent by the source (information source, also known as the sending terminal) without modulation (spectru...

Abstract

Disclosed is a network device, a signal processing device, and an antenna device, wherein the network device includes a baseband, a radio remote device, and an antenna device, and the antenna device includes a splitter and five groups of antenna elements, and the baseband is used to generate At least one signal, and at least one signal is transmitted to the remote radio device; the remote radio device is used to receive the signal from the baseband, and forward it to the antenna device after frequency conversion, and the splitter of the antenna device is used for the radio frequency The signal sent by the remote device is split and processed, and finally mapped on different antenna arrays to achieve the desired beam; the network equipment of this application uses a special antenna structure, combined with independent baseband side beamforming signals between different systems The processing method realizes UMTS multi-sector and LTE system 4T4R MIMO concurrency in the same frequency band, realizes mutual compatibility of the two platforms, and improves network capacity at the same time.

Description

technical field [0001] The present application relates to the communication field, and in particular to a network device, a signal processing device and an antenna device. Background technique [0002] Improving network capacity has always been an important issue in the development of wireless networks. In the Long Term Evolution (LTE) system, the demand for data is gradually increasing, resulting in an increasing demand for network capacity. For a general universal mobile telecommunications system (UMTS), although most of the data has been migrated to a higher standard in the agreement, operators will still carry out spectrum refarming (Refarming) of UMTS or LTE, such as re-planning the spectrum resources, and use the remaining bandwidth capacity of the UMTS network for other standards, so that the UMTS network will still face the pressure of capacity shortage. [0003] In order to alleviate the pressure on network capacity, each network standard has launched corresponding...
