Claim Rejections - 35 USC § 103
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
Claims 1, 5-16, 20-22, 24-28, 30 are rejected under 35 U.S.C. 103 as being unpatentable over Li (US 20250286671) in view of Rafique (US 20250251508).
Regarding Claims 1, Li teaches the following limitations:
A method at a sensing node of non-linear frequency-modulated (NLFM) radio frequency (RF) sensing, the method comprising: (Li - [0002] This application belongs to the field of communication sensing technologies, and specifically relates to a resource configuration method, a resource determining method and apparatus, a communication device, and a storage medium. [0052] In a mobile communication network, a base station (including one or more TRPs on the base station, a user equipment (User Equipment, UE, or a “terminal”) (including one or more antenna sub-arrays/panels (Panels) on the UE)) may serve as a sensing node participating in a sensing or an ISAC service. [0054] When a Doppler frequency shift of a target echo is large, a large ranging error is generated. A sidelobe level of an autocorrelation function of a nonlinear frequency modulation signal (Non LFM, NLFM) is improved, but there is still a large range sidelobe on a high Doppler frequency section of an ambiguity function. A sidelobe of a large target or clutter covers a mainlobe of a small target near the sidelobe. In a multi-target environment, synthesis of a plurality of sidelobes of a target response may even cover a mainlobe of a stronger target response. It can be learned that there is a problem in the related art that signal sensing performance is poor. Li teaches “Costa Array” and does not explicitly teach non-linear frequency-modulated (NLFM) radio frequency (RF) sensing.)
receiving an NLFM configuration at the sensing node from a configuring node of a wireless network, (Li – [Abstract] The resource configuration method in embodiments of this application includes: configuring, by a signal sending node, a first resource based on a predetermined first array, where the first array includes at least one Costas array or at least one Costas array set, and each Costas array set includes at least one Costas array; and sending, by the signal sending node, a first signal by using the first resource. [0053] In the embodiments of this application, the signal sending node and the signal receiving node may be a same device or different devices. For example, a sensing node A sends a first signal, a sensing node B receives the first signal, and the sensing node A and the sensing node B are not a same device and are separated in physical locations; or a sensing node A sends and receives a first signal, in other words, the sensing signal is sent and received by a same device, and the sensing node senses by receiving a signal echo sent by the sensing node. For ease of description, in the embodiments of this application, that the signal sending node and the signal receiving node are different devices is used as an example for description. [0129] the signal sending node receives first configuration information, where the first configuration information is used for configuring the first signal;)
wherein the NLFM configuration is indicative of a set of one or more parameters of a non-linear function describing time-varying frequency characteristics of an NLFM signal to be used by the sensing node for RF sensing; and (Li – [Fig. 3a-b], [0055] In the embodiments of this application, a first resource is configured through a Costas array, and a first signal is sent by using the first resource. Because a Costas array has a special sequence structure, and Costas arrays of different orders all have a “pin-shaped” ambiguity function, a resource sequence of a first resource configured based on the Costas array also has a “pin-shaped” ambiguity function. The first signal is sent by using the first resource, so that a main peak of the first signal is high and sharp, a sub-peak is low and flat, and a signal resolution is high. It can be learned that signal sensing performance can be improved according to this embodiment of this application.)
performing an RF sensing function with the sensing node in accordance with the NLFM configuration. (Li – [0052], [0053], [0055] first signal is sent by using the first resource Li does not explicitly teach “NLFM configuration”.)
Li does not explicitly teach the following limitations, however Rafique, in the same field of endeavor, teaches:
non-linear frequency-modulated (NLFM) radio frequency (RF) sensing (Rafique – [0164] A reference signal may be determined by a standard, a configuration of transmitter and/or receiver, and/or the like. Identification of sensing signal is explained in detail in section Identification of sensing signals… a first reference signal waveform may comprise one or more non-linear chirps, i.e. NL-FM chirps. At least one of the one or more non-linear chirps may be, for instance, a hyperbolic chirp. For example, a first non-linear chirp out of the one or more non-linear chirps has an increasing frequency and a second non-linear chirp out of the one or more non-linear chirps has a decreasing frequency. Corresponding to the transmitting of the sensing signal, the second reference waveform may be a linear chirp.)
Therefore, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to have modified the Costa Arrays of Li with the NLFM configuration of Rafique in order to improve sidelobe suppression (Rafique – [0100]).
Regarding Claim 5, Li further teaches:
wherein the sensing node comprises a user equipment (UE) or a base station. (Li - [0052])
Regarding Claim 6, Li further teaches:
wherein: the set of parameters comprises one of a plurality of parameter sets included in the NLFM configuration; and (Li – [0129], [0110] The structure of the first array is, for example, an order of a Costas array and a type of the Costas array. The type of the Costas array may include at least one of a Welch-Costas array, a Golomb-Costas array, and a Lempel-Costas array. Once the structure of the first array is determined, a relative position of a time-frequency resource element to which the first array is mapped is determined. The position of the time-frequency resource to which the first array is mapped is, for example, a position of the Costas array in the available time-frequency resource. [0111] Once the structure of the first array and the position of the time-frequency resource to which the first array is mapped are determined, an absolute position of the time-frequency resource to which the first array is mapped is determined, and the signal sending node may configure the first resource based on the absolute position of the time-frequency resource to which the first array is mapped. Li does not explicitly teach “NLFM capability information”.)
performing the RF sensing function is based at least in part on a trigger message received from a base station, the trigger message identifying the set of parameters from the plurality of parameter sets. (Li – [0052], [0053], [0129], [0247] As shown in FIG. 7b, when the sensing signal is configured as the aperiodic perceptual signal, the network side device triggers sending and measurement of the CSI-RS through a method of sending DCI 0_1 or MAC CE+DCI 0_1.)
Li does not explicitly teach the following limitations, however Rafique, in the same field of endeavor, teaches:
NLFM configuration (Rafique – [0164])
Therefore, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to have modified the Costa Arrays of Li with the NLFM configuration of Rafique in order to improve sidelobe suppression (Rafique – [0100]).
Regarding Claims 7, 14, Li further teaches:
wherein the sensing node comprises a transmit (Tx) sensing node, and (Li – [0052], [0053])
wherein performing the RF sensing function in accordance with the NLFM configuration comprises transmitting the NLFM signal. (Li – [0052], [0053], [0129])
Li does not explicitly teach the following limitations, however Rafique, in the same field of endeavor, teaches:
NLFM configuration (Rafique – [0164])
Therefore, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to have modified the Costa Arrays of Li with the NLFM configuration of Rafique in order to improve sidelobe suppression (Rafique – [0100]).
Regarding Claims 8, 26, Li further teaches:
wherein transmitting the NLFM signal comprises transmitting one or more repetitions of the NLFM signal in a symbol of an orthogonal frequency division multiplexing (OFDM) communication scheme. (Li – [Fig. 3a-b], [0093] In an example, FIG. 3a and FIG. 3b provide schematic diagrams of resource mapping relationships of two Costas arrays in the OFDM. FIG. 3a shows two Costas arrays, orders of the two Costas arrays are both 6, and FIG. 3b shows one Costas array, and an order of the Costas array is 12. In all examples in this embodiment of this application, it is default that sub-carrier indexes in one RB are 0 to 11, and OFDM symbol indexes in one slot (Slot) are 0 to 13.)
Li does not explicitly teach the following limitations, however Rafique, in the same field of endeavor, teaches:
NLFM signal (Rafique – [0164])
Therefore, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to have modified the Costa Arrays of Li with the NLFM configuration of Rafique in order to improve sidelobe suppression (Rafique – [0100]).
Regarding Claim 9, Li further teaches:
wherein the OFDM communication scheme comprises cyclic prefix (CP)-OFDM in which each OFDM symbol is preceded by a period of time allocated for a CP, and (Li – [Fig. 3a-b], [0093] Li does not explicitly teach “cyclic prefix (CP)-OFDM”.)
wherein transmitting the one or more repetitions of the NLFM signal in the symbol comprises transmitting the one or more repetitions such that: there is a first period of time prior to the beginning of the one or more repetitions during which the sensing node makes no transmission, (Li – [0176] an OFDM frame, or a time length of any pre-defined size in a time domain.)
the first period of time comprising the period of time allocated for a CP immediately preceding the symbol; and (Li – [Fig. 3a-b], [0093], [0176])
there is a second period of time between the end of the symbol and the end of the one or more repetitions during which the sensing node makes no transmission. (Li – [Fig. 3a-b], [0093], [0176])
Li does not explicitly teach the following limitations, however Rafique, in the same field of endeavor, teaches:
cyclic prefix (CP)-OFDM (Rafique – [0126] Due to the presence of orthogonal subcarriers, OFDM delivers high multiplexing capabilities in time and frequency through OFDM resource elements. The cyclic prefix converts the linear convolution of the transmit signal with the propagation channel impulse response to a circular convolution hence enabling simple frequency domain equalization at the receiver. [0127] A suitable sensing and/or communication performance may not be effectively feasible with a single fixed frame design and transmission mechanism. Each design and mechanism has its own advantages and drawbacks. Therefore, an adaptive and flexible frame design and transmission mechanism selection framework may be advantageous.)
Therefore, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to have modified the OFDM of Li with the cyclic prefix of Rafique in order to operate over 4G and 5G networks (Rafique – [0126]).

appending a second FMCW signal to the end of the one or more repetitions such that the second FMCW signal is transmitted prior to end of the symbol. (Li – [Fig. 3a-b], [0093], [0176])
Li does not explicitly teach the following limitations, however Rafique, in the same field of endeavor, teaches:

In addition, the radio frequency unit 1401 may send uplink data to the network side device.

Therefore, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to have modified the Costa Array configuration and mapping of Li with the transmitter and receiver capabilities of Rafique in order to configure a transmitting or receiving device (Rafique – [0139]).
Li does not explicitly teach the following limitations, however Cho, in the same field of endeavor, teaches:
a maximum order of LPs, a maximum frequency ramping speed, or a combination thereof. (Cho – [0085], [0092])
Therefore, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to have modified the ambiguity function and Costa Array mapping of Li with the Legendre Polynomials of Cho in order to calibrate an amplitude error (Cho – [0085]).
Regarding Claim 29, Li further teaches:
wherein the one or more processors are configured to receive NLFM capability information from the sensing node prior to determining the NLFM configuration,
wherein the NLFM capability information is indicative of: (Li – [0110], [0111], [0129])
