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

The invention discloses network equipment, a signal processing device and an antenna device. The network equipment comprises a baseband, a radio frequency remote device and the antenna device; the antenna device comprises a branching unit and five groups of antenna arrays; the baseband is used for generating at least one signal and transmitting at least one signal to the radio frequency remote device; the radio frequency remote device is used for receiving signals from a baseband and forwarding the signals to the antenna device after frequency conversion, and the branching unit of the antennadevice is used for branching the signals sent by the radio frequency remote device and finally mapping the signals on different antenna arrays so as to realize expected wave beams. According to the network equipment provided by the invention, through a special antenna structure and in combination with an independent baseband side beamforming signal processing method among different systems, UMTS multi-sector and LTE system 4T4R MIMO same-frequency-band concurrency is realized, mutual compatibility of two platforms is realized, and meanwhile, the network capacity is improved.

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...
