1, Xing teaches a method for wireless communications at a user equipment (UE), comprising: identifying a set of carriers within a frequency band for communicating with a base station via carrier aggregation [par 0039, if the UE wants to use the CA to transmit a service, the UE should select one or more carriers in the carrier set corresponding to the service. If the UE transmits multiple services at the same time, the UE should select carriers from multiple carrier sets corresponding to multiple services as the carriers in the carrier set. In this case, the carrier set A may be configured to be 4 carriers on a certain frequency band, or a size of the carrier set A is limited to no more than 2 according to the transmission capability of 2];
Xing fail to show measuring, based on downlink signals transmitted by the network entity, a first downlink power spectral density of a first carrier of the set of carriers and a second downlink power spectral density of a second carrier of the set of carriers; and the set of carriers within the frequency band, the first parameter comprising a difference between the first downlink power spectral density for the first carrier and the second downlink power spectral density for the second carrier.
In an analogous art Filipovic show measuring, based on downlink signals transmitted by the network entity, a first downlink power spectral density of a first carrier of the set of carriers and a second downlink power spectral density of a second carrier of the set of carriers; and the set of carriers within the frequency band [par 0006, 0008, 0025, In one aspect, at a remote terminal, a power spectral distribution (PSD) of received signals is sequentially measured in contiguous segments of a frequency band of interest. In another aspect, a PSD of received signals is measured within a frequency band of interest; and a plurality of characteristics of the measured PSD are compared to a respective plurality of predetermined metrics to identify at least one technology type of the received signals in locations across the band. Accordingly, as described, embodiments of power scan unit 320 may be configured to measure a PSD of received signals within a segment of a frequency band of interest, and to compare detected carrier frequencies within the PSD to a set of predetermined carrier frequencies, to derive a bias in frequency estimation of the wireless terminal, such as a bias due to the terminal's clock unit]
the first parameter comprising a difference between the first downlink power spectral density for the first carrier and the second downlink power spectral density for the second carrier[par 0067, The bias can be equal to a difference between the detected and predetermined carrier frequencies. Alternatively, the bias can be equal to a difference between the detected and predetermined carriers for a most likely carrier of a particular communication type. As a further alternative, the bias can be equal to a difference between the detected and predetermined carriers for a strongest carrier of a particular communication technology type];
Before the effective filing date it would have been obvious to one of ordinary skill in the art to combine the teaching of Xing and Filipovic because this provides r improving system acquisition in an environment of co-existing technologies over a common frequency band are disclosed. In one aspect, at a remote terminal, a power spectral distribution (PSD) of received signals is sequentially measured in contiguous segments of a frequency band of interest. [Filipovic, par 0006]
Xing and Filipovic fail to show refraining from communicating over a first carrier of the set of carriers within the frequency band based at least in part on a first parameter for communications over the first carrier exceeding a threshold with respect to corresponding parameters of other carriers of the set of carriers within the frequency band.
In an analogous art TaKaoka show refraining from communicating over a first carrier of the set of carriers within the frequency band based at least in part on a first parameter for communications over the first carrier exceeding a threshold with respect to corresponding parameters of other carriers of the set of carriers within the frequency band [par 0127, 0139, 140, 0143, In power scaling method 12, power scaling controlling section 109 preferentially drops an SRS having a low PSD over an SRS having a high PSD (lowers the power allocation priority, reduces the transmission power, stops the transmission, or sets the transmission power to be equal to zero). When a difference in PSD of SRS between CCs is large, the intermodulation distortion of the SRS on the CC having a higher PSD may become larger than a PSD of an SRS on a different CC. This intermodulation distortion cannot be removed by a transmission filter. In addition, it is also possible to introduce a threshold for PSDs or the abovementioned parameters and to preferentially drop the corresponding SRS when these values exceed the threshold],
Before the effective filing date it would have been obvious to one of ordinary skill in the art to combine the teachings of Xing, Filipovic and Takaoka because this provides a method of selecting a CC for multiplexing important UCI to which no retransmission is applied, on the power allocation priority used when power scaling occurs in simultaneous transmission of a plurality of periodic SRSes on a plurality of CCs
8, Xing, Filipovic and Takaoka describe the method of claim 1, Xing and Filipovic fail to show further comprising: determining, subsequent to the refraining, that a second parameter for communicating over a second carrier of the set of carriers exceeds the threshold; and communicating over the first carrier and the second carrier based at least in part on the first parameter and the second parameter exceeding the threshold.
In an analogous art Takoka show further comprising: determining, subsequent to the refraining, that a second parameter for communicating over a second carrier of the set of carriers exceeds the threshold; and communicating over the first carrier and the second carrier based at least in part on the first parameter and the second parameter exceeding the threshold[par 0139, 0140, 0143, in power scaling method 12, power scaling controlling section 109 preferentially drops an SRS having a low PSD over an SRS having a high PSD (lowers the power allocation priority, reduces the transmission power, stops the transmission, or sets the transmission power to be equal to zero). When a difference in PSD of SRS between CCs is large, the intermodulation distortion of the SRS on the CC having a higher PSD may become larger than a PSD of an SRS on a different CC. This intermodulation distortion cannot be removed by a transmission filter. Specifically, when the SRS is transmitted without removal of the intermodulation distortion, the eNB measures the communication quality of the CC by the SRS affected by the intermodulation distortion. As a result, correct scheduling or transmission power control cannot be performed. With respect to this problem, transmission of only an SRS having a high PSD, which is unlikely to be affected by the intermodulation distortion, allows an eNB to perform measurement on the CC with high accuracy].

Response to Arguments
Takaoka goes on to describe that transmitting an SRS having a high PSD will be unlikely to be affected by intermodulation distortion, allowing the eNB to perform a more accurate measurement of communication quality of the carrier. [0140]. However, Takaoka does not teach transmitting only a high-PSD SRS based on a downlink PSD of downlink signals transmitted by the eNB.
The examiner respectfully disagrees the applicant claim does not state the base station only transmits high-PSD SRS based on a downlink PSD of downlink signals, therefore the applicant’s argument is moot.
There is no indication, in Takaoka, that the referenced PSD of an SRS is a downlink PSD.
The examiner respectfully disagrees in Takaoka paragraphs 0091, 0133, An aperiodic SRS is the SRS that is newly introduced into LTE-A and configured to be triggered by a PDCCH, which is a physical layer downlink control channel, for an eNB to measure new quality information with low delay.
In power scaling method 11, when a plurality of SRSes of Scells is present, power scaling controlling section 109 raises the power allocation priority for the SRS on a CC on which UCI is triggered (to be triggered) by control information included in a physical layer control channel PDCCH (UL or DL grant) or control information reported (to be reported) via higher layer signaling, of the plurality of SRSes of the Scells. The paragraphs show SRS on a CC triggered by control information included in a physical layer control channel PDCCH (UL or DL grant).
Indeed, in Takaoka, it is the UE that is transmitting SRS. If anything, Takaoka suggests the use of an uplink PSD.
Thus, Takaoka does not teach or suggest at least the above-recited limitation in amended independent claim 1. Further, Lin, Gao, Xing '602, Akula, Lahr, Xu, and Guan do not overcome the deficiencies of Xing, nor does the Office Action suggest otherwise. Therefore, for at least these reasons, amended independent claim 1 is allowable over any combination of Xing, Takaoka, Lin, Gao, Xing '602, Akula, Lahr, Xu, and Guan. Amended independent claims 23, 29, and 30 are likewise allowable for at least similar reasons.
The examiner respectfully disagrees in para 0148, 0262, 0285 of Takaoka shows Furthermore, as a method of reducing the transmission power of an SRS with low power allocation priority, an SRS scaling weight reported from an eNB to a terminal (via higher layer signaling) may be used to reduce the transmission power.
The operation described above is used because an (e.g., aperiodic) SRS is likely to be transmitted on a CC which has been indicated by higher layer signaling such as RRC from the eNB and which has higher priority as an Scell used in reporting periodic CQI (PMI).
Furthermore, as a method of reducing the transmission power of an SRS with low power allocation priority described above, an SRS scaling weight reported from an eNB to a terminal (via higher layer signaling) may be used to reduce the transmission power, the paragraphs show the enb transmits the SRS.
