With regard to independent claims:
Regarding claim 1, ZHOU teaches an apparatus (component in UE 114 in fig. 1, Fig. 7: UE 702) for wireless communication at a first wireless communication device (see fig. 1: UE 114) (see fig. 1 where UE 114 is in wireless communication with Base Station 104; “The wireless communication system 100 may operate pursuant to a wireless standard, for example the IEEE 802.11 standard.

For example, the message may include the frame structure 500 including the power backoff per MCS information. For example, an AP may be configured to transmit the message containing the power backoff per MCS information to a STA. As another example, a STA may be configured to transmit the message containing the power backoff per MCS information an AP. In some examples, certain power backoffs for reference MCSs may be signaled (e.g. transmitted to a receiving device), and one or more power backoffs corresponding to one or more MCSs may be interpolated (e.g., by the receiving device) based on the signaled power backoff information for the reference MCSs. For example, a power backoff of 1 dB for reference MCS3 and a power backoff of 3 dB for reference MCSS may be signaled and power backoff of 2 dB may be interpolated for MCS4 (which may not be signaled). For example, an MCS component of the receiving device of transmit power related information (e.g., an AP or a STA) may be configured to interpolate one or more power backoffs based on received power backoff per MCS information.

For example, power backoff per MCS information for a STA may refer to a transmit power backoff from a maximum transmit power of a transmitter of the STA to prevent the transmitter (e.g., the power amplifier (PA) of the transmitter) of the STA from entering a non-linear state. As an example, if the transmit power of a STA increases from 20 dB to 30 dB, the increase in the transmit power may cause the PA of the transmitter to enter a non-linear region of operation which may distort the signal.

For example, in an example, the best MCS (e.g., for a UL transmission from the STA to the AP) may be defined as the highest MCS (or highest MCS index/MCS index value) with a packet error rate (PER) below a threshold at the estimated SINR for this MCS. In some examples, the backoff per MCS may be a function of bandwidth (e.g., channel bandwidth), number of spatial streams, and/or pre-coding matrix.

Regarding claim 17 : ZHOU in view of YANG do not expressively teach, wherein the one or more processors are further configured to: receive an indication of an estimated nonlinearity of a transmission port used to transmit the communication, wherein the estimated nonlinearity of the transmission port is based at least in part on the indication of the power amplifier nonlinearity state .
Stopler, in the same field of endeavor, discloses:
wherein the one or more processors are further configured to: receive an indication of an estimated nonlinearity of a transmission port used to transmit the communication, wherein the estimated nonlinearity of the transmission port is based at least in part on the indication of the power amplifier nonlinearity state (Fig. 3A-3C: Digital nonlinear Function (DNF) which estimate nonlinear distortion: [0111]-[0112]; see Fig. 2 DFP circuit 102 “optimized to compress the transmitted signal to limit out-of-band distortion introduced by the Power Amplifier (e.g. reducing cubic metric) and maximize receiver performance.”: [0033]).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the teaching of ZHOU in view of YANG to include the above recited limitations as taught by Stopler. The suggestion/motivation to do so would have been to improve the functionally of integrated circuit or chip (Stopler:[0127]).
Regarding claim 24, ZHOU in view of YANG do not expressively teach,
wherein the one or more processors, to estimate the nonlinearity of the communication based at least in part on reception of the set of communications are configured to :
estimate the nonlinearity based at least in part on pilot measurements of the set of communications transmitted by the second wireless communication device.
Stopler, in the same field of endeavor, discloses:
wherein the one or more processors, to estimate the nonlinearity of the communication based at least in part on reception of the set of communications are configured to :
estimate the nonlinearity based at least in part on pilot measurements of the set of communications transmitted by the second wireless communication device (“the adjustment of the one or more components may be controlled based on order of a modulation constellation used for generation of the symbol. The adjustment of the one or more components may be controlled based on a determination of interference present at a receiver to which said symbol is to be transmitted.”: [0122]; “The at least one nonlinear circuit may comprise a power amplifier and/or a digital pre-distortion circuit. The at least one nonlinear circuit may comprise a digital nonlinear function circuit configured to compress a signal to be transmitted prior to input of the signal to be transmitted to a power amplifier of the transmitter. The said generation of the pre-distortion signal may be based on a seeking of a minimum, maximum, or desired value (e.g., above or below a threshold) of a performance metric. The transmitter may comprise a pilot distortion circuit (e.g., bin mapper 116 or multiplier 390) operable to distort pilots of said symbol.”: [0123]).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the teaching of ZHOU in view of YANG to include the above recited limitations as taught by Stopler. The suggestion/motivation to do so would have been to improve the functionally of integrated circuit or chip (Stopler:[0127]).
Conclusion
Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a).
A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
