[0071] The following will be combined with the accompanying drawings to clearly and thoroughly describe the technical solutions in the embodiments of the present application. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B; "and / or" in the text is only a description of the association relationship of the associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

[0072] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features, and in the description of the embodiments of the present application, unless otherwise specified, "plurality" means two or more.

[0073] The inventors have found that with the geometric growth of wireless services, the communication capacity, spectrum utilization efficiency and system complexity of wireless communication systems are facing new challenges. Although CA can be used to increase system bandwidth and improve system communication capacity, multiple combinations of CA will introduce MUX, which will increase the complexity of the system solution and increase the insertion loss of the RF front end, which will have a serious impact on the power consumption of the entire device.

[0074] Spurious emission refers to the radiation at discrete frequencies other than the carrier frequency and the sidebands and adjacent channels caused by normal modulation and switching transients when modulated with a standard signal, including harmonic emission, parasitic emission, intermodulation products and frequency conversion products. In traditional wireless communication schemes, only the carrier is used for information transmission, while the role of spurious signals is ignored, resulting in its spectrum resources being idle and wasted. The embodiments of the present application provide a solution on how to utilize the spectrum resources of spurious signals to improve the channel capacity of the wireless communication system.

[0075] In view of this, the present application proposes a network-side device for wireless communication to solve the above problems. The inventive concept of the present application can be summarized as follows: in the wireless communication network-side device, an amplifier (Power Amplifier, PA) controller is added, and the parameters of the PA are adjusted by the PA controller, and the spurious wave spectrum resources generated by the PA operation are used to convert the serial signal into n parallel signals and then perform signal modulation, at least one signal is modulated onto the corresponding spurious wave to obtain n modulated signals, and the n modulated signals are beamformed and transmitted to the wireless channel.

[0076] like Figure 1 , which is a schematic diagram of the structure of the network side device for wireless communication in the embodiment of the present application. The figure includes: a data source 101, a serial-to-parallel converter 102, a PA controller 103, an amplifier 104, a radio frequency signal modulator 105, a beamformer 106, and a transmitting antenna 107, wherein:

[0077] A data source 101 is configured to generate a serial signal to be transmitted;

[0078] In one embodiment, the serial bit stream generated by the data source may be a serial random binary bit stream.

[0079] A serial-to-parallel converter 102 is configured to convert a serial signal into n parallel signals;

[0080] The PA controller 103 is used to control the amplifier 104 to generate m-channel spurious waves, wherein n and m are both positive integers;

[0081] In one embodiment, since spurious waves are generated when the amplifier is working, the amplifier can be controlled to generate m-channel spurious waves within a preset frequency range by adjusting the parameters of the amplifier; wherein the parameters of the amplifier include at least one of the following: gain state, switching time, duty cycle, etc. Any parameters related to generating a spurious wave spectrum are applicable to the embodiments of the present application.

[0082] In one embodiment, since the transmission rates of different communication systems are different, the number of paths of the selected spurious waves should be determined based on the transmission rate. Therefore, based on the transmission rate of the communication system, the current transmission rate of the system is used as the target transmission rate. The target transmission rate has a positive correlation with the number of paths of the selected spurious waves, that is, the higher the transmission rate, the more paths of the selected spurious waves. Therefore, the parameters of the amplifier can be determined based on the positive correlation. For example, the number of paths of the selected spurious waves corresponding to multiple groups of transmission rates can be determined in advance according to experiments and stored. When the number of paths of the selected spurious waves is determined next time, the number of paths of the currently selected spurious waves can be directly obtained from the number of paths of the selected spurious waves corresponding to the pre-stored transmission rates.

[0083] In one embodiment, since the environment of the spatial channel affects the transmission of the signal and the attenuation degree of spurious waves of different frequencies is different, in order to select spurious waves suitable for transmission in the spatial channel, the frequency range of the spurious waves should be set according to the environment of the spatial channel and the attenuation degree of the spurious waves of different frequencies, and the frequency range is used as the preset frequency range, so that the spurious waves with frequencies within the preset frequency range can be selected for signal modulation according to the frequencies corresponding to the m-channel spurious waves. That is, according to the frequencies corresponding to the spurious waves, the spurious waves with small attenuation and not occupied by other users are selected for signal modulation.

[0084] The radio frequency signal modulator 105 is configured to perform signal modulation on the n parallel signals to obtain n modulated signals, wherein at least one parallel signal of the n parallel signals is modulated onto a corresponding spurious wave;

[0085] In one embodiment, n parallel signals may be respectively mapped to corresponding spurious waves for signal modulation (i.e., all signals are modulated with spurious waves); wherein one spurious wave carries one parallel signal; in this method, all signals are modulated with spurious waves, which may result in a waste of normal carrier resources and a low transmission rate.

[0086] Therefore, in another embodiment, at least one of the n parallel signals is mapped to a corresponding spurious wave for signal modulation; and the remaining parallel signals are mapped to a corresponding reference carrier for signal modulation (i.e., part of the n signals are modulated with spurious waves, and part of the signals are modulated with the reference carrier); wherein one spurious wave carries one parallel signal, and one reference carrier carries one parallel signal.

[0087] In order to avoid interference to other users in the wireless channel, the beamformer 106 is configured to perform beamforming on the n modulated signals and then transmit the signals through the transmitting antenna 107 .

[0088] For ease of understanding, the following signal processing method is used to accurately describe the above process:

[0089] The data source 101 generates a serial binary bit stream; the serial-to-parallel converter 102 converts the serial binary bit stream into K+1 parallel binary bit streams, wherein K channels are modulated by spurious waves and 1 channel is modulated by a reference carrier.

[0090] The serial-to-parallel converter output k (t), k = 1, 2 ... K} are all unipolar binary baseband signals, and the binary information {a k , k=1,2…K} takes 1 or 0, then the baseband binary signal of each channel can be expressed as:

[0091] p k (t) = a k g T (tT b ), (k=1,2…K) (Formula 1)

[0092] Where: g T is a unipolar non-return-to-zero square wave with an amplitude of 1, T b Binary symbol time interval.

[0093] The PA controller 103 controls the amplifier 104 to generate m-channel spurious waves, from which K-channel spurious waves are selected according to a preset frequency for signal modulation;

[0094] The spectrum of the K-path spurious wave generated by the PA controller controlling the amplifier is:

[0095] c k (t,ω k )=A k cos(ω k ·t), (k=1,2…K) (Formula 2)

[0096] Among them: A k is the amplitude corresponding to the stray wave frequency component, ωk =2πf k , f k are the component frequencies corresponding to each spurious wave.

[0097] The RF signal modulator 105, according to {p k (t), k=1,2…K} and {c k (t,ω k ), k=1,2…K} for stray RF signal modulation;

[0098] Get the spurious RF modulation signal:

[0099] s k (t,ω k )=p k (t)c k (t,ω k ),(k=1,2,K) (Formula 3)

[0100] The stray RF modulated signal is sent to the beamformer through parallel signal transmission lines for beamforming to obtain the combined transmission signal:

[0101]

[0102] Finally, the combined transmission signal is sent to the wireless channel through the transmitting antenna, so that the receiving end (such as the device in 2) can receive the signal and demodulate the signal. The terminal device in the embodiment of the present application is described in detail below:

[0103] The embodiment is specifically described by taking the communication terminal 100 as an example.
