For example, the receiving device 904 may update its estimate of the effective power amplifier model that is used by the DPoD component 920 to apply DPoD to a received signal. Fig. 16, Para. [0030]-Kutz discloses example of signaling to indicate a change in a non-linearity model. Fig. 4, Para. [0091-0092]-Kutz discloses the slot 410 including a control region 412 and a data region 414. In general, the control region 412 may carry control channels, and the data region 414 may carry data channels ... the various REs 406 within an RB 408 may be scheduled to carry one or more physical channels, including control channels, shared channels, data channels, etc. Other REs 406 within the RB 408 may also carry pilots or reference signals. These pilots or reference signals may provide for a receiving device to perform channel estimation of the corresponding channel, which may enable coherent demodulation/detection of the control and/or data channels within the RB 408. Para. [0095]-Kutz discloses the base station may further allocate one or more REs 406 (e.g., in the control region 412 or the data region 414) to carry other DL signals, such as a demodulation reference signal (DMRS). Para. [0094]-Kutz discloses the scheduling entity (e.g., a base station) may allocate one or more REs 406 (e.g., within the control region 412) to carry DL control information including one or more DL control channels, such as a physical downlink control channel (PDCCH), to one or more scheduled entities (e.g., UEs).

These pilots or reference signals may provide for a receiving device to perform channel estimation of the corresponding channel, which may enable coherent demodulation/detection of the control and/or data channels within the RB 408. Para. [0095]-Kutz discloses the base station may further allocate one or more REs 406 (e.g., in the control region 412 or the data region 414) to carry other DL signals, such as a demodulation reference signal (DMRS)); and
decode respective data signaling during each slot of the plurality of slots based at least in part on whether the respective control signaling indicates to update, or not to update, the estimation of the non-linear characteristics of the power amplifier of the network entity (Para. [0011]-Kutz discloses receiving, from a second wireless communication device, an indication {control channel} of a change in a non-linearity model for a power amplifier circuit comprising a digital pre-distorter of the second wireless communication device ... updating non-linearity information for a digital post-distorter of the first wireless communication device after the receiving the indication ... receiving a signal {data channel} from the second wireless communication device ... using the digital post-distortion to compensate for non-linear distortion in the signal. Para. [0134]-Kutz discloses the DPoD process iteratively removes an estimate of the non-linear distortion component d to restore the original data signal x by using a correction step, a slicing step, and a non-linear distortion estimation step. Para. [0078]-Kutz discloses control function can be implemented with an interface configured to communicate signals with other control functions ..., for network control and signaling. Para. [0094]-Kutz discloses the scheduling entity (e.g., a base station) may allocate one or more REs 406 (e.g., within the control region 412) to carry DL control information including one or more DL control channels, such as a physical downlink control channel (PDCCH), to one or more scheduled entities (e.g., UEs)),
the decoding uses an updated estimation of the non-linear characteristics of the power amplifier when the respective control signaling indicates to update the estimation of the non-linear characteristics of the power amplifier (Para. [0011]-Kutz discloses receiving, from a second wireless communication device, an indication of a change in a non-linearity model for a power amplifier circuit ... updating non-linearity information for a digital post-distorter of the first wireless communication device after the receiving the indication ... receiving a signal from the second wireless communication device ... using the digital post-distortion to compensate for non-linear distortion in the signal. Para. [0141]-Kutz discloses estimation of the non-linearity model G(x) ... the receiving device may apply a least-squares estimation). The resulting new set of kernels and coefficients provides the updated G(x) that the DPoD component 920 will use in the non-linearity distortion estimation phase. Para. [0134]-Kutz discloses the DPoD process iteratively removes an estimate of the non-linear distortion component d to restore the original data signal x by using a correction step, a slicing step, and a non-linear distortion estimation step. Para. [0094]-Kutz discloses the scheduling entity (e.g., a base station) may allocate one or more REs 406 (e.g., within the control region 412) to carry DL control information including one or more DL control channels, such as a physical downlink control channel (PDCCH), to one or more scheduled entities (e.g., UEs)), and
the decoding uses a previous estimation of the non-linear characteristics of the power amplifier when the respective control signaling indicates not to update the estimation of the non-linear characteristics of the power amplifier (Para. [0133]-Kutz discloses the receiving device 904 may maintain a local copy of the non-linearity model (e.g., an estimate of the effective power amplifier model) for use by the DPoD component 920. Para. [0143]-Kutz discloses the transmitting device 902 may transmit the indication 924 and the non-linearity parameters 926 {for when change in parameter is zero} in the same transmission (e.g., in a single message). Table 1, Figs. 9 and 12, Para. [0156-0163]-Kutz discloses the DPoD process of a receiving device, ..., a receiving device may receive a data signal y that includes a non-linear distortion component d ... the DPoD process is based on modeling the non-linear distortion as an additive signal ... the output of a power amplifier (PA) 1202 of a transmitting device may be represented by y=G(x)=ax+d ... y(x) is the received signal at a receiving device after channel equalization. The signal y(x) (i.e., y) is based on the original data signal x at the transmitting device ... the original data signal x is subject to non-linear distortion (e.g., at the CFR 908, the DPD 910, and the PA 912 of FIG. 9). The term G(x) represents this non-linear distortion model ... The parameter {circumflex over (d)} in Table 1 may represent the non-linear distortion that occurred at the transmitting device. The DPoD reconstruction procedure involves estimating the non-linear distortion {circumflex over (d)} in the received signal. With each iteration of the loop, a more accurate estimate of x and {circumflex over (d)} can be obtained ... Initially, {circumflex over (d)} is set to 0. Para. [0094]-Kutz discloses the scheduling entity (e.g., a base station) may allocate one or more REs 406 (e.g., within the control region 412) to carry DL control information including one or more DL control channels, such as a physical downlink control channel (PDCCH), to one or more scheduled entities (e.g., UEs)).
Kutz fails to explicitly teach receive, during each slot of a plurality of slots scheduled for one or more data transmissions, respective control signaling indicating whether to update, or not to update, an estimation of the non-linear characteristics of the power amplifier of the network entity.
However, Lee teaches receive, during each slot of a plurality of slots scheduled for one or more data transmissions, respective control signaling indicating whether to update, or not to update, an estimation of the non-linear characteristics of the power amplifier of the network entity (Table 1, Para. [0114]-Lee discloses transmit 1-bit information indicating the need to change the NC {nonlinear compensator} model to the receiver, and the receiver may learn the NC model whenever information indicating the need to change {Corresponding to indicating whether to update, or not to update} the NC model is received. Para. [0124]-Lee discloses the receiver always performs the NC model learning in every slot in a scheduling unit. Para. [0181]-Lee discloses it is natural to learn or apply the changed NC model from the frame, subframe or slot in which the NSI is transmitted. Para. [0197]-Lee discloses the base station may transmit the NSI (e.g., NSI #Y) corresponding to the changed nonlinearity to the terminal. In this case, similarly, the base ... station may transmit an RS necessary for learning the NC model to be changed, and the corresponding NSI (e.g., NSI #Y) may be related to the RS. The NSI may be transmitted through a DCI, MAC CE, RRC message, or a combination thereof according to the frequency or period in which the nonlinearity is changed. In this case, the message or information through which the NSI is transmitted may include information indicating a related RS (e.g., RS resource index, or the like). Para. [0194]-Lee discloses the base station may transmit the NSI (e.g., NSI #X) related to the RS together with an RS required for NC model learning. The NSI may be transmitted through a DCI, MAC CE, RRC message, or a combination thereof according to the frequency or period in which the nonlinearity is changed. In this case, the message or information through which the NSI is transmitted may include information indicating a related RS (e.g., RS resource index, or the like)).
Kutz and Lee are both considered to be analogous to the claimed invention because they are in the same field of wireless communication system, dealing with method and apparatus for efficient data transmission between a base station and a terminal.
Therefore, it would have been obvious to someone of ordinary skill in the art before the effective filing date of the claimed invention to have modified the Kutz to incorporate the teachings of Lee on non-linear characteristics of power amplifiers, with a motivation to indicate whether to update, or not to update, an estimation of the non-linear characteristics, and support communication via one or more cells, (Kutz, Para. [0003]).
Regarding claims 2 and 13, Kutz in view of Lee teaches the UE of claim 1 and the method of claim 12 respectively,
Kutz further teaches receive one or more demodulation reference signals with the respective data signaling during a first slot of the plurality of slots (Para. [0095]-Kutz discloses the base station may further allocate one or more REs 406 (e.g., in the control region 412 or the data region 414) to carry other DL signals, such as a demodulation reference signal (DMRS). Para. [0094]-Kutz discloses the scheduling entity (e.g., a base station) may allocate one or more REs 406 (e.g., within the control region 412) to carry DL control information including one or more DL control channels, such as a physical downlink control channel (PDCCH), to one or more scheduled entities (e.g., UEs)),
estimating the updated non-linear characteristics of the power amplifier of the network entity for the first slot is based at least in part on performing a digital post-distortion correction to the one or more demodulation reference signals (Para. [0011]-Kutz discloses receiving, from a second wireless communication device, an indication of a change in a non-linearity model for a power amplifier circuit comprising a digital pre-distorter of the second wireless communication device ... updating non-linearity information for a digital post-distorter of the first wireless communication device after the receiving the indication ... receiving a signal from the second wireless communication device ... using the digital post-distortion to compensate for non-linear distortion in the signal. Para. [0134]-Kutz discloses the DPoD process iteratively removes an estimate of the non-linear distortion component d to restore the original data signal x by using a correction step, a slicing step, and a non-linear distortion estimation step).
Regarding claims 4, 11, 15 and 22, Kutz in view of Lee teaches the UE of claim 1, The network entity of claim 5 and The method of claim 12 and the method of claim 16 respectively,
Kutz fails to teach one bit indicator.
However, Lee teaches the respective control signaling comprises a one bit indicator of whether to update, or not to update, the estimation of the non-linear characteristics of the power amplifier of the network entity (Table 1, Para. [0114]-Lee discloses transmit 1-bit information indicating the need to change the NC {nonlinear compensator} model to the receiver, and the receiver may learn the NC model whenever information indicating the need to change the NC model is received).
Kutz and Lee are both considered to be analogous to the claimed invention because they are in the same field of wireless communication system, dealing with method and apparatus for efficient data transmission between a base station and a terminal.
Therefore, it would have been obvious to someone of ordinary skill in the art before the effective filing date of the claimed invention to have modified the Kutz to incorporate the teachings of Lee on non-linear characteristics of power amplifiers, with a motivation to indicate changes using 1-bit indicator, and support high data rates in wider coverage, and smooth cooperation between a terminal and a base station, (Lee, Para. [0008-0009]).

The method may include determining a change in a non-linearity model for a power amplifier circuit that includes a digital pre-distorter. The method may also include transmitting an indication of the change in the non-linearity model to a second wireless communication device) to cause the network entity to:

Of course, a slot may contain all DL, all UL, or at least one DL portion and at least one UL portion. The structure illustrated in FIG. 4 is merely an example, and different slot structures may be utilized, and may include one or more of each of the control region(s) and data region(s). Para.

In the remarks, on page 10, Lines [16-18], Applicant argues that, “…the Office Action has not shown that Kutz discloses all the features of independent claim 1, much less all of the features arranged or combined in the same way as recited in independent claim 1.”
However, in Para. [0412]-Kutz discloses the components, steps, features and/or functions illustrated in FIGS. 1-27 may be rearranged and/or combined into a single component, step, feature, or function or embodied in several components, steps, or functions. Additional elements, components, steps, and/or functions may also be added without departing from novel features.
In the remarks, on page 11, Lines [1-3], Applicant argues that, “…the Office Action has not shown that Kutz discloses a per-slot indication of whether or not to update estimation of non-linear characteristics.”
However, in Para. [0059]-Kutz discloses the uplink control information 118, downlink control information 114, downlink traffic 112, and/or uplink traffic 116 may be time-divided into frames, subframes, slots, and/or symbols ... A slot may carry 7 or 14 OFDM symbols in some examples; while,

In the remarks, on page 11, Lines [26-27], Applicant argues that, “…Kutz has not been shown to disclose such features as recited in dependent claim 7.”
However, Kutz teaches transmit the respective control signaling indicating the UE is to update the estimation of the non-linear characteristics of the power amplifier of the network entity based at least in part on a time duration between non-linear characteristic estimation updates satisfying a threshold (Para. [0135]-Kutz discloses non-linearity model may change over time. For example, one or more attributes (e.g., temperature, etc.) associated with the power amplifier 912 may change over time. A change in such an attribute may affect the power amplifier state, thereby resulting in a change in the non-linearity imparted on a signal by the power amplifier 912. Para.

In the remarks, on page 13, Lines [9-10], Applicant argues that, “…Kutz has not been shown to disclose such features as recited in dependent claim 8.”
However, Kutz teaches transmit, during each slot of the plurality of slots, the respective control signaling indicating the UE is to update the estimation of the non-linear characteristics of the power amplifier of the network entity based at least in part on a time duration between a previous data signaling to the UE and the respective data signaling during the slot satisfying a threshold (Para.

In the remarks, on page 15, Lines [1-5], Applicant argues that, “…the Office Action fails to demonstrate that Lee discloses or suggests "receive, during each slot of a plurality of slots scheduled for one or more data transmissions, respective control signaling indicating whether to update, or not to update, an estimation of the non-linear characteristics of the power amplifier of the network entity," as recited in amended independent claim 1.”
However, Lee teaches receive, during each slot of a plurality of slots scheduled for one or more data transmissions, respective control signaling indicating whether to update, or not to update, an estimation of the non-linear characteristics of the power amplifier of the network entity (Table 1, Para. [0114]-Lee discloses transmit 1-bit information indicating the need to change the NC {nonlinear compensator} model to the receiver, and the receiver may learn the NC model whenever information indicating the need to change {Corresponding to indicating whether to update, or not to update} the NC model is received. Para. [0124]-Lee discloses the receiver always performs the NC model learning in every slot in a scheduling unit. Para. [0181]-Lee discloses it is natural to learn or apply the changed NC model from the frame, subframe or slot in which the NSI is transmitted. Para. [0197]-Lee discloses the base station may transmit the NSI (e.g., NSI #Y) corresponding to the changed nonlinearity to the terminal. In this case, similarly, the base ... station may transmit an RS necessary for learning the NC model to be changed, and the corresponding NSI (e.g., NSI #Y) may be related to the RS. The NSI may be transmitted through a DCI, MAC CE, RRC message, or a combination thereof according to the frequency or period in which the nonlinearity is changed. In this case, the message or information through which the NSI is transmitted may include information indicating a related RS (e.g., RS resource index, or the like). Para. [0194]-Lee discloses the base station may transmit the NSI (e.g., NSI #X) related to the RS together with an RS required for NC model learning. The NSI may be transmitted through a DCI, MAC CE, RRC message, or a combination thereof according to the frequency or period in which the nonlinearity is changed. In this case, the message or information through which the NSI is transmitted may include information indicating a related RS (e.g., RS resource index, or the like)).
