Fig. 1 shows a block diagram of a wireless communication system to which embodiments of the present application are applicable. The wireless communication system includes a terminal 11 and a network device 12. The terminal 11 may be a mobile phone, a tablet (Tablet Personal Computer), a Laptop (Laptop Computer) or a terminal-side Device called a notebook, a personal digital assistant (Personal Digital Assistant, PDA), a palm top, a netbook, an ultra-mobile personal Computer (ultra-mobile personal Computer, UMPC), a mobile internet appliance (Mobile Internet Device, MID), an augmented reality (augmented reality, AR)/Virtual Reality (VR) Device, a robot, a Wearable Device (weather Device), a vehicle-mounted Device (VUE), a pedestrian terminal (PUE), a smart home (home Device with a wireless communication function, such as a refrigerator, a television, a washing machine, or a furniture), a game machine, a personal Computer (personal Computer, PC), a teller machine, or a self-service machine, and the Wearable Device includes: intelligent wrist-watch, intelligent bracelet, intelligent earphone, intelligent glasses, intelligent ornament (intelligent bracelet, intelligent ring, intelligent necklace, intelligent anklet, intelligent foot chain etc.), intelligent wrist strap, intelligent clothing etc..

For ease of understanding, some of the matters related to the embodiments of the present application are described below:

1. terminal Capability (UE Capability) reporting.

Cellular wireless communication systems rely on accurate and efficient coordination and interworking between base stations and UEs, where UE Capability is an important ring of coordination between base stations and UEs. The base station knows the UE capabilities before it can make the correct scheduling for the UE. If the UE supports a certain function, the base station may configure the function for the UE; if the UE does not support a certain function, the base station may not configure the function for the UE.

1.1, UE Capability mainly involves two flows: UE Capability request and UE Capability report. When the base station needs the UE to report the UE Capability, the base station can issue a terminal Capability query (UE Capability requirement) instruction to the UE. And after receiving the UE capability information instruction, the UE reports the terminal capability information (UE capability information) according to the instruction. Wherein a Filter (Filter) in the UE Capability requirement signaling indicates which UE capabilities the UE base station specifically wants to know.

1.2, UE Capability signaling structure.

Optionally, UE Capability is divided into different levels of Capability.

UE Capability of terminal specific (UE specific): each UE may have different capabilities that apply to all carriers and carrier combinations supported by the UE.

UE Capability at carrier Combination (Band Combination) level: each Band Combination may be configured with different capabilities, such as a Band Combination for Band3+ Band77 may be configured to support a certain UE capability and a Band Combination for Band1+ Band78 may be configured to not support the UE capability.

Carrier (Band) level UE Capability: each Band may have different capabilities, such as Band77 supporting a certain UE capability, while Band78 may not support that UE capability.

Another method for classifying the UE capabilities is to classify according to protocol stacks, and when UE capabilities are actually reported, reporting is also performed according to protocol stack layering, where UE capabilities reporting is divided into:

packet data convergence protocol parameter (Packet Data Convergence Protocol Parameters, PDCP-Parameters): UE Capability corresponding to the PDCP layer;

radio link control Parameters (Radio Link Control Parameters, RLC-Parameters): UE Capability corresponding to the RLC layer;

media access control Parameters (Medium Access Control Parameters, MAC-Parameters): UE Capability corresponding to the MAC layer;

physical layer Parameters (Physical Parameters, PHY-Parameters): UE Capability corresponding to the PHY layer;

radio frequency Parameters (Radio Frequency Parameters, RF-Parameters): RF related UE Capability.

2. PA is nonlinear.

Radio frequency power amplifiers (also referred to as power amplifiers) are an important component of a transmission system. At the front end of the signal transmitting path, the linearization degree of the power amplifier can directly influence the transmitting quality of the signal. In practical situations, however, in order to increase the conversion efficiency of the power amplifier as much as possible, the Peak-to-Average Power Ratio (PAPR) will often drive the power amplifier to operate in a nonlinear region or even a saturation region, so that the power amplifier output signal generates distortion of amplitude and Phase information due to the difference of the instantaneous amplitude of the input signal, that is, nonlinear distortion of amplitude Modulation-amplitude Modulation (Amplitude Modulation-Amplitude Modulation) and/or amplitude Modulation-Phase Modulation (Amplitude Modulation-Phase Modulation, AM-PM) of the signal.

Ideally, the transmission characteristics of the PA are linear, i.e., the output of the power amplifier is a linear multiple of the input. However, in practice the transmission characteristics of the PA do not always meet the linearity requirements. When the input of the power amplifier is a small signal, the output of the PA is a linear amplification of the input, and when the power of the input signal of the PA is gradually increased, the output of the PA will reach a saturated state, and the input and output of the PA show a nonlinear relationship.

The transmission signal may suffer from both in-band and out-of-band distortions due to the nonlinear effects of the PA. In-band distortion manifests itself as compression of the amplitude and phase shift of the transmitted signal, i.e. constellation dispersion of the modulated signal. The in-band distortion can lead to the detection judgment of the error of the receiver, and the error rate of the system is increased; out-of-band distortion, in turn, manifests itself in the transmission signal producing new spectral components such that the spectrum is spread, and such distortion can cause interference to adjacent channels. Both types of distortion coexist and affect the performance of the communication system.

Alternatively, based on the AM-AM characteristic and the AM-PM characteristic, the power amplifier can maintain linear amplification substantially when the signal power is small, and gradually enter a saturation region as the input signal power increases, the output power no longer increases as the input power increases, and the phase aspect generates jitter and rotation of the constellation.

3. Predistortion (Digital Pre-Distortion, DPD).

The principle of DPD is: the nonlinear distortion function is built in the digital, digital baseband signal processing domain by cascading a predistortion element with a power amplifier element (PA), which is comparable ("equal") to the amount of distortion exhibited by the amplifier, but the opposite function. Combining these two nonlinear distortion functions enables a highly linear, distortion-free system. The challenge with digital predistortion techniques is that the distortion (i.e., non-linear) characteristics of the PA can change with time, temperature, and bias voltage (bias) changes, from device to device. Thus, while it is possible to determine the characteristics and design the correct predistortion algorithm for one device, it is not economically viable to do so for every device. To solve the above-mentioned deviation, a feedback mechanism is used to sample the output signal and correct the predistortion algorithm. Digital predistortion is implemented using digital circuitry to implement this Predistorter (Predistorter), typically using digital signal processing. The nonlinearity of the power amplifier is compensated by adding a nonlinearity circuit. This allows a simple class AB platform to be used within the Power Amplifier (PA), thereby eliminating the burden and complexity of manufacturing the feed forward amplifier (feedforward amplifier) from the base station manufacturer. In addition, since the amplifier no longer needs an error amplifier distortion correction circuit, the system efficiency can be significantly improved.

4. Digital post-distortion (Digital Post distortion, DPoD).

DPoD does not attempt to remove nonlinear distortion, mainly by performing nonlinear compensation operation at the receiving end, thereby improving signal detection. And according to the nonlinear characteristics estimated by the UE, the UE carries out digital distortion adjustment on the received signal so as to correctly demodulate the transmitted signal.

The capability reporting processing method provided by the embodiment of the application is described in detail below by means of some embodiments and application scenarios thereof with reference to the accompanying drawings.

Referring to fig. 2, an embodiment of the present application provides a capability reporting processing method, as shown in fig. 2, where the capability reporting processing method includes:

in step 201, a terminal sends first information to a network side device, where the first information includes capability information indicating whether the terminal supports nonlinear distortion processing.

In an embodiment of the present application, the first information may be carried by at least one of the following:

layer 1 signaling carried by the physical uplink control channel (Physical Uplink Control Channel, PUCCH);

message 1 (MSG 1) carried by a physical random access channel (Physical Random Access Channel, PRACH);

message 3 (MSG 3) carried by PRACH;

message a (MSGA) carried by PRACH;

Physical uplink shared channel (Physical Uplink Shared Channel, PUSCH).

The above message 1, message 3 and message a are messages in the random access procedure. The above capability information may also be referred to as terminal wireless capability information.

It should be understood that after the network side device receives the first information sent by the terminal, whether the power amplifier in the network side device can work in a nonlinear region can be determined based on the capability information, for example, when the terminal has the capability of nonlinear distortion processing, the power amplifier of the network side device can work in the nonlinear region, so that the power efficiency can be improved, and the energy consumption of the network side device can be further reduced.

According to the method and the device for processing the nonlinear distortion, the terminal sends the first information to the network side device, and the capability information is used for indicating whether the terminal has the capability of nonlinear distortion processing or not, so that the network side device can enable the power amplifier of the network side device to work in a nonlinear region when the terminal has the capability of nonlinear distortion processing, and therefore power efficiency can be improved, and energy consumption of the network side device is further reduced.

Optionally, in some embodiments, the capability information may include at least one of:

First capability information for indicating whether the terminal supports estimating a nonlinear characteristic;

second capability information for indicating whether the terminal supports feeding back the estimated nonlinear characteristics to the network side device;

third capability information for indicating whether the terminal supports performing a post-digital distortion operation on the received signal according to the estimated nonlinear characteristics;

a first bit field for indicating whether the terminal supports the nonlinear distortion processing;

a second bit field, where the second bit field is used to indicate relevant information that the terminal supports the nonlinear distortion processing, and the relevant information includes at least one of the following: the type of non-linear characteristic, the range of non-linear characteristic, the frequency range, the subcarrier spacing (Subcarrier Spacing, SCS), the modulation and coding scheme (Modulation and Coding Scheme, MCS), the power range, the signal-to-noise ratio (Signal Noise Ratio, SNR) range, and the signal-to-interference-plus-noise ratio (Signal to Interference plus Noise Ratio, SINR) range.

In the embodiment of the present application, the nonlinear distortion processing may be understood to include at least one of the following:

the terminal estimates nonlinear characteristics;

The terminal feeds the estimated nonlinear characteristics back to the network side equipment;

the terminal performs a digital post-distortion operation on the received signal according to the estimated nonlinear characteristics.

The above-mentioned first capability information may be understood as the capability of the terminal to estimate the non-linear characteristic. The second capability information may be understood as the capability of the terminal to feed back the estimated nonlinear characteristics to the network side device. The above-described third capability information may be understood as the capability of the terminal to perform a digital post-distortion operation on the received signal according to the estimated nonlinear characteristics.

The ability of the terminal to estimate the nonlinear characteristic may be understood as whether the terminal supports the ability to estimate the nonlinear characteristic, the ability of the terminal to feed back the estimated nonlinear characteristic to the network side device may be understood as whether the terminal supports the ability to feed back the estimated nonlinear characteristic to the network side device, and the ability of the terminal to perform the digital post-distortion operation on the received signal according to the estimated nonlinear characteristic may be understood as whether the terminal supports the ability to perform the digital post-distortion operation on the received signal according to the estimated nonlinear characteristic.

When the terminal supports the capability of estimating the nonlinear characteristic and the capability of feeding back the estimated nonlinear characteristic to the network side device, the network side device can acquire the nonlinear characteristic fed back by the terminal, so that predistortion processing can be performed based on the nonlinear characteristic fed back by the terminal, and therefore, the power amplifier of the network side device can work in a nonlinear region under the condition that the terminal normally receives signals, and further, the power efficiency can be improved, and the energy consumption of the network side device can be reduced. When the terminal supports the ability to estimate the nonlinear characteristics and the ability to perform digital post-distortion operation on the received signal according to the estimated nonlinear characteristics, the terminal may perform digital post-distortion processing on the nonlinear distorted signal transmitted by the network side device, thereby obtaining a normal signal. Therefore, the power amplifier of the network side equipment can work in a nonlinear area under the condition that the terminal normally receives signals, so that the power efficiency can be improved, and the energy consumption of the network side equipment is reduced.

It should be understood that the above-described first bit field may include one or more bits indicating that the terminal supports or does not support the nonlinear distortion process, wherein the terminal supports the nonlinear distortion process may be understood as at least one of supporting estimating nonlinear characteristics, feeding back the estimated nonlinear characteristics to a network side device, and performing a digital post-distortion operation on a received signal according to the estimated nonlinear characteristics. The terminal not supporting the nonlinear distortion processing may be understood as at least one of not supporting the estimation of the nonlinear characteristics, not supporting the feedback of the estimated nonlinear characteristics to the network side device, and not supporting the execution of the digital post-distortion operation on the received signal according to the estimated nonlinear characteristics. In addition, the first bit field may also indicate whether to support the estimation of the nonlinear characteristic, whether to support the feedback of the estimated nonlinear characteristic to the network side device, and whether to perform the digital post-distortion operation on the received signal according to the estimated nonlinear characteristic, respectively, through a plurality of bits.

The above-mentioned second bit field may be associated with a certain capability supported by the terminal, for example, when the capability information indicates that the terminal supports estimating the nonlinear characteristic, the second bit field is used to indicate related information supporting estimating the nonlinear characteristic, for example, indicates a type of nonlinear characteristic and a range of nonlinear characteristics supporting estimating the nonlinear characteristic, and the like. In this way, the second bit field indicates that the terminal supports the relevant information for performing the nonlinear distortion processing, so that the pertinence of nonlinear distortion of signals can be improved, the range of signal distortion is further limited, and the terminal can normally receive signals, so that the reliability of communication can be further improved.

In the embodiment of the invention, the first information is sent to the network side equipment through the terminal, and the first information comprises the capability information indicating whether the terminal supports nonlinear distortion processing, so that the network side equipment can determine whether the power amplifier works in a nonlinear region based on the capability information whether the terminal supports nonlinear distortion processing, and the problem that the terminal cannot normally receive signals sent by the network side equipment due to the fact that the power amplifier of the network side equipment works in the nonlinear region under the condition that the terminal does not support the capability of nonlinear distortion processing is effectively avoided. Therefore, the embodiment of the application improves the reliability of communication. Meanwhile, under the condition that the terminal supports the capability of supporting nonlinear distortion processing, the network side equipment can determine whether the power amplifier works in a nonlinear area according to actual conditions, and when the power amplifier of the network side equipment can work in the nonlinear area, the power efficiency can be improved, and the energy consumption of the network side equipment is further reduced.

Optionally, in some embodiments, at least one of the first capability information, the second capability information, and the third capability information includes at least one of: the type of non-linear characteristics, the range of non-linear characteristics, the frequency range, the subcarrier spacing, the modulation and coding scheme, the power range, the SNR range, and the SINR range.

In this embodiment of the present application, specific behaviors of the nonlinear processing are different, and the corresponding supporting capability may include multiple types, for example, the type of nonlinear characteristics supporting the nonlinear distortion processing may include at least one of the following:

supporting a nonlinear characteristic type for estimating nonlinear characteristics;

supporting the feedback of the estimated nonlinear characteristics to the nonlinear characteristic type of the network side equipment;

the type of nonlinear characteristics that perform a digital post-distortion operation on the received signal based on the estimated nonlinear characteristics is supported.

It should be appreciated that in embodiments of the present application, when the terminal supports estimating the nonlinear characteristics, the first capability information may include at least one of a nonlinear characteristic type, a nonlinear characteristic range, a frequency range, a subcarrier spacing, a modulation and coding scheme, a power range, an SNR range, and an SINR range. When the terminal supports feeding back the estimated non-linear characteristic to the network side device, the second capability information may include at least one of a non-linear characteristic type, a non-linear characteristic range, a frequency range, a subcarrier spacing, a modulation and coding scheme, a power range, an SNR range, and an SINR range. When the terminal supports performing a digital post-distortion operation on the received signal according to the estimated nonlinear characteristics, the third capability information may include at least one of a nonlinear characteristic type, a nonlinear characteristic range, a frequency range, a subcarrier spacing, a modulation and coding scheme, a power range, an SNR range, and an SINR range. The flexibility of capability information indication is improved because the related information of specific behaviors is carried in different capability information.

Alternatively, the types of nonlinear characteristics corresponding to the behaviors of the three different nonlinear distortion processes may be the same or different, for example, the types of nonlinear characteristics supporting the estimation of nonlinear characteristics include at least one of a type of nonlinear characteristics supporting the feedback of the estimated nonlinear characteristics to the network side device and a type of nonlinear characteristics performing a digital post-distortion operation on the received signal according to the estimated nonlinear characteristics.

The type of nonlinear characteristics described above may include at least one of amplitude and phase.

The nonlinear characteristic range may include at least one of a maximum offset value, a minimum offset value, an offset value average value, an offset value variance, and an offset value standard deviation.

The frequency domain range may include at least one of an operating frequency band, a bandwidth, a lowest frequency, and a highest frequency.

The power range may include at least one of a maximum value, a minimum value, a median value, an average value, a standard deviation, and a variance of power; the SNR range may include at least one of a maximum value, a minimum power value, a median value, an average value, a standard deviation, and a variance of SNR; the SINR range may include at least one of a maximum value, a minimum power value, a median value, an average value, a standard deviation, and a variance of SINR.

Optionally, in some embodiments, after the terminal sends the first information to the network side device, the method further includes:

the terminal receives an acknowledgement message from the network side equipment, wherein the acknowledgement message comprises at least one of the following:

the first indication information is used for indicating that the network side equipment receives the capability information;

second indication information, wherein the second indication information is used for indicating at least one of the terminal use supporting capability, and the supporting capability is the capability of the nonlinear distortion processing supported by the capability information indication;

a transmission parameter for the terminal to estimate at least one signal of a nonlinear characteristic;

time-frequency resource position information for the nonlinear characteristics of the terminal feedback estimation;

whether to transmit a signal having a nonlinear characteristic;

transmission parameters of signals having non-linear characteristics.

In the embodiment of the present application, when the capability information indicates the capability of the supported nonlinear distortion processing, the method includes:

the terminal estimates nonlinear characteristics;

The network side device may instruct the terminal to use the capability of the terminal to estimate the nonlinear characteristic and the capability of the terminal to feed back the estimated nonlinear characteristic to the network side device through the second instruction information, and may instruct the terminal to use the capability of the terminal to estimate the nonlinear characteristic and the capability of the terminal to perform the digital post-distortion operation on the received signal according to the estimated nonlinear characteristic through the second instruction information. Further, when the capability information indicates that the capability of the supported nonlinear distortion processing includes supporting a nonlinear characteristic type for performing the nonlinear distortion processing, the second indication information may further indicate that the terminal uses a specific nonlinear characteristic type among the supported nonlinear characteristic types.

Alternatively, when the acknowledgement message includes transmission parameters of at least one signal for the terminal to estimate the nonlinear characteristics and time-frequency resource location information for the terminal to feed back the estimated nonlinear characteristics, the terminal may perform estimation of the nonlinear characteristics of the signal based on the transmission parameters of the at least one signal and feed back the estimated nonlinear characteristics to the network-side device through the time-frequency resource location information.

Optionally, the transmission parameters of the signal having the nonlinear characteristic are used for receiving the signal having the nonlinear characteristic. The signal may include at least one signal for the terminal to estimate the non-linear characteristic and other signals actually used for transmission.

Optionally, the acknowledgement message is carried by at least one of:

a medium access control unit (Medium Access Control Control Element, MAC CE);

a radio resource control (Radio Resource Control, RRC) message;

non-access stratum (NAS) messages;

user plane data;

downlink control information (Downlink Control Information, DCI);

system information blocks (System Information Block, SIB);

layer 1 signaling carried by the physical downlink control channel (Physical downlink control channel, PDCCH);

a physical downlink shared channel (Physical downlink shared channel, PDSCH);

message 2 carried by PRACH;

message 4 carried by PRACH;

message B carried by PRACH.

The message 2, the message 4 and the message B are messages in the random access process.

Further, the terminal has a nonlinear distortion processing capability, and when the network side device determines that the power amplifier works in the nonlinear region, the network side device can send a signal for estimating the nonlinear characteristic of the terminal, and then the terminal performs nonlinear characteristic estimation based on the signal. For example, in the case that the terminal has the capability of nonlinear distortion processing, after the terminal sends the first information to the network side device, the method further includes:

The terminal receives a first signal sent by the network side equipment, wherein the first signal has nonlinear characteristics;

the terminal carries out nonlinear characteristic estimation based on the first signal to obtain target nonlinear characteristics;

the target nonlinear characteristic is used for the terminal to execute digital post-distortion operation or used for the network side equipment to execute predistortion operation.

In this embodiment of the present application, the terminal may receive the first signal based on the transmission parameter corresponding to the first signal carried in the acknowledgement message, and then perform nonlinear characteristic estimation to obtain the target nonlinear characteristic.

Alternatively, the corresponding operations performed for the target nonlinear characteristics are different based on the different support capabilities of the terminal use. For example, in some embodiments, after the terminal estimates a nonlinear characteristic based on the first signal, the method further comprises any one of:

the terminal feeds back the target nonlinear characteristic to the network side equipment;

the terminal performs a digital post-distortion operation on a second signal based on the target nonlinear characteristic.

In the embodiment of the application, when the terminal supports and uses the capability of feeding back the estimated nonlinear characteristics to the network side equipment, the terminal can feed back the target nonlinear characteristics to the network side equipment. When a terminal supports and uses a digital post-distortion operation on a received signal according to an estimated nonlinear characteristic, the terminal performs a digital post-distortion operation on a second signal based on the target nonlinear characteristic. The second signal is understood to be the signal actually used for transmission, i.e. used for implementing communication functions other than the non-linear characteristic estimation.

The method for sending the first information to the network side device by the terminal may be active reporting by the terminal or a request from the network side device, where the terminal may report to the network side device when the terminal is initially accessed, or may report periodically. If the terminal is requested by the network side device, before the terminal sends the first information to the network side device, the method further includes:

the terminal receives a request command from the network side device, wherein the request command is used for requesting the terminal to send the first information.

In this embodiment of the present application, the request command may be carried by at least one of the following: MAC CE, RRC message, NAS message, user plane data, layer 1 signaling of DCI, SIB, PDCCH, PDSCH, message 2 of PRACH, message 4 of PRACH, and message B of PRACH.

For a better understanding of the present application, the following detailed description is provided by way of some specific examples.

Referring to fig. 3, the terminal capability information is reported by adopting a query and response mode, which specifically includes the following procedures:

step 31, after the terminal enters the RRC connected state, the base station issues a terminal capability query command (corresponding to the request command) to the terminal, where the terminal capability query command is used to request the terminal to report capability information. Wherein, the signaling of the terminal capability inquiry command indicates which terminal capability the base station wants to know.

And step 32, reporting the terminal capability information according to the command after the terminal receives the terminal inquiry command.

The signaling of the terminal capability information may carry the following information:

ability of UE to estimate signal non-linearity characteristics: if the UE supports estimated signal non-linearity/amplitude distortion/phase distortion/amplitude distortion + phase distortion; the UE supports at least one of maximum offset value, minimum offset value, offset average value, offset value variance, offset value standard deviation, operating band, bandwidth, lowest frequency, highest frequency, SCS, MCS, power range, SNR range, and SINR range of the estimated signal nonlinear characteristic/amplitude distortion/phase distortion.

The ability of the UE to feed back the estimated non-linear characteristics to the base station: such as whether the UE supports feedback non-linear characteristics/amplitude distortion/phase distortion/amplitude distortion + phase distortion; the UE supports at least one of a maximum offset value, a minimum offset value, an offset average value, an offset value variance, an offset value standard deviation, an operating band, a bandwidth, a lowest frequency, a highest frequency, SCS, MCS, power range, SNR range, and SINR range of the feedback nonlinear characteristic/amplitude distortion/phase distortion.

The ability of the UE to perform digital post-distortion operations on the received signal based on the estimated nonlinear characteristics, such as whether the UE supports performing digital post-distortion operations based on the estimated nonlinear characteristics/amplitude distortion/phase distortion/amplitude distortion + phase distortion; at least one of a maximum offset value, a minimum offset value, an offset average value, an offset value variance, an offset value standard deviation, an operating band, a bandwidth, a lowest frequency, a highest frequency, an SCS, an MCS, a power range, an SNR range, and an SINR range of nonlinear characteristics/amplitude distortion/phase distortion supported when the UE performs the digital post-distortion operation.

In step 33, the base station sends an acknowledgement message to the terminal.

Optionally, the base station may send acknowledgement information to the UE after receiving the nonlinear distortion handling capability reported by the UE.

Based on the difference in the capability supported by the acknowledgement message and the terminal, the corresponding behavior of the base station and the terminal is different, so that the optional execution steps indicated by the dashed lines in fig. 3 are executed, and the following description will be made for different cases.

Case 1: if the UE supports estimating signal non-linearity/amplitude/phase distortion, the acknowledgement information may include the time-frequency location at which the base station transmits information for non-linearity estimation to the UE. Information for nonlinear characteristic estimation is then transmitted at the corresponding time-frequency location, from which the UE estimates signal nonlinear characteristics, such as amplitude distortion, phase distortion. At this time, the terminal may decide whether to report the estimated nonlinear characteristic, thereby deciding to perform predistortion by the network side device or perform digital post-distortion operation by the terminal, so that the power amplifier of the network side device may operate in a nonlinear region.

Case 2: if the UE supports estimating signal nonlinear characteristics/amplitude distortion/phase distortion and supports feedback to the base station, the acknowledgement information may include time-frequency location where the base station transmits information for nonlinear characteristics estimation to the UE and time-frequency resource information for feedback by the UE. And the UE feeds back the estimated nonlinear characteristics to the base station on the allocated feedback resources after estimating the nonlinear characteristics according to the information sent by the base station. The terminal feeds back the estimated nonlinear characteristic to the network side equipment, so that the network side equipment can execute predistortion, the power amplifier of the network side equipment can work in a nonlinear area, and the terminal is not required to execute digital post-distortion operation, thereby reducing the electric quantity loss of the terminal.

Case 3: if the UE supports estimating signal nonlinear characteristics/amplitude distortion/phase distortion and supports performing a digital post-distortion operation based on the estimated nonlinear characteristics, the confirmation information may include time-frequency positions at which the base station transmits information for nonlinear characteristics estimation to the UE and parameter information with nonlinear characteristics signals/data that the base station subsequently transmits. After the nonlinear characteristics are estimated according to the information sent by the base station, the UE receives signals/data with the nonlinear characteristics according to the parameter information indicated by the base station, performs digital post-distortion operation on the received signals based on the estimated nonlinear characteristics, and then performs corresponding demodulation operation. Therefore, the terminal does not need to report the estimated nonlinear characteristics, thereby saving signaling overhead.

Case 4: if the UE supports estimating signal nonlinear characteristics/amplitude distortion/phase distortion and supports feedback to the base station and supports performing digital post-distortion operations based on the estimated nonlinear characteristics, the acknowledgement information may include, in addition to information in case 1, case 2, and case 3, the base station configuration indicating the UE to use specific nonlinear distortion processing capabilities, e.g., indicating the UE to use only estimated signal phase distortion capabilities, and the ability to feed back the estimated nonlinear characteristics to the base station. In the embodiment of the application, the network side equipment indicates the terminal use capability, so that the terminal use capability can be flexibly adjusted according to the communication state, and the communication reliability can be further improved.

Case 5: if the UE does not support estimating the signal nonlinearity, the UE cannot support feeding back the estimated nonlinearity to the base station and digital post-distortion operation. After the UE reports that the nonlinear characteristics of the estimated signal are not supported, the acknowledgement information may include that the base station receives the nonlinear distortion processing capability information of the UE, and the base station does not send information for estimating the nonlinear characteristics of the UE any more later, and the base station cannot send signals/data with the nonlinear characteristics. Since information for the UE to estimate the nonlinear characteristics is not transmitted any more, waste of resources can be avoided. In addition, the base station does not send the signal/data with nonlinear characteristics, so that the situation that the terminal cannot normally receive the signal/data with nonlinear characteristics sent by the network side equipment is avoided, and the reliability of communication can be improved.

In some embodiments, the terminal capability information may be actively reported by the terminal, for example, when the terminal is first registered for network access, the UE actively reports its own UE capability information through NSA signaling. The method specifically comprises the following steps:

step 41, the terminal establishes RRC connection, and the terminal reports own terminal capability information to the core network through a message 2, wherein the message 2 is an initial terminal message;

In step 42, the core network device sends a message 4 to the base station, the message 4 being an initial context setup request (Initial context setup request).

Optionally, if the message 4 carries a cell (Information element, IE) of the terminal wireless capability information, the base station does not perform steps 43 to 45, and if the message 4 does not carry a cell of the terminal wireless capability information, steps 43 to 45 are performed;

step 43, the base station initiates a UE capability query procedure;

step 44, the terminal reports the wireless capability information of the terminal to the base station;

in step 45, the base station sends a capability information indication (Capability Info Indication) to a mobility management entity (Mobility Management Entity, MME) in the core network, and transmits and reports terminal wireless capability information to the MME.
