DETAILED ACTION
This action is responsive to the communications filed on 8/26/2024.
Currently, claim 1 is pending.
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Claim Rejections - 35 USC § 102
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale or otherwise available to the public before the effective filing date of the claimed invention.
(a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention.
Claim 1 is concurrently rejected under 35 U.S.C. 102(a)(1) and 102(a)(2) as being anticipated by Kang et al. (US 2010/0110874: hereinafter “Kang”).
With regards to claim 1, Kang teaches an apparatus and method (figs. 3-5 and 19: see [0056] for IEEE 802.16m and the per frame parameters (within each superframe) are shown by Table 1, see at least [0051-0055]. Note [0055] addresses the subframes in a frame may change based on the selected channel bandwidth, CP length, etc (as shown in Table 1). Note that the method steps are implemented as functions of the hardware), comprising:
a processor configured for generating a data frame (figs. 3-5 and 19: at least the processor(s) 1920 and 1930 of the transmitter (in figure 19 which performs the functions of figure 3-5) meets this limitation. Where the superframe header of the data superframe may be broadcast [0050], thus the superframe itself may be broadcast wirelessly. Note that the ‘superframe of Kang’ is mapped to the claimed “data frame”); and
a transmitter configured to wirelessly broadcast the data frame (figs. 3-5 and 19: at least the processor(s) 1920 and 1930 of the transmitter (in figure 19 which performs the functions of figure 3-5) meets this limitation. Where the superframe header of the data superframe may be broadcast [0050], thus the superframe itself may be broadcast wirelessly),
wherein the data frame (figs. 3-5 and 19: as previously addressed the parameters of Table 1 (including different FFT sizes, useful portion, and cyclic prefix CP ratio/lengths) are ‘selected per 5ms frame’ within a single superframe (the superframe was previously mapped to the claimed ‘data frame’).
The first set of OFDM symbols is mapped to first frame F0 (which includes OFDM symbols with useful portion and non-useful portions (e.g. the prepended CP)); and the second set of OFDM symbols is mapped to second frame F1 (which includes OFDM symbols with useful portion and non-useful portions (e.g. the prepended CP)). The frame parameters are selected from Table 1 and may be the same or different from one another) comprises: generating a first set of orthogonal frequency domain multiplexing (OFDM) symbols; and generating a second set of OFDM symbols, wherein each OFDM symbol in the first set of OFDM symbols and the second set of OFDM symbols comprises a useful portion and a cyclic prefix (CP) (figs. 3-5 and 19: as previously addressed the parameters of Table 1 (including different FFT sizes, useful portion, and cyclic prefix (CP) ratio/lengths) are ‘selected per 5ms frame’ within a single superframe.
The first set of OFDM symbols is mapped to first frame F0, which includes a plurality of OFDM symbols, where each OFDM symbol in the first set of OFDM symbols individually includes ‘useful/data portion’ and ‘prepended CP’.
The second set of OFDM symbols is mapped to second frame F1, which includes a plurality of OFDM symbols, where each OFDM symbol in the second set of OFDM symbols individually includes ‘useful/data portion’ and ‘prepended CP’.
Where the frame parameters are selected from Table 1 and may be the same or different from one another), and
wherein generating said each OFDM symbol (the processor(s) were previously addressed, and also generate each of the OFDM symbols), the processor is further configured for or further comprises (addressed below):
converting a block of frequency domain data to time-domain samples using an inverse fast Fourier transform having a transform size to form the useful portion (figs. 3-5 and 19: the transmitter functions/step are shown by the figure 3 elements 202-214, which perform the stated functions. For example, the digital samples are converted from the frequency domain to the time domain via M-point IDFT/IFFT unit 208 (based on the selected FFT size for respective frame from TABLE 1) and then the CP (based on the selected CP size/ratio from TABLE 1) is prepended to each of the OFDM symbols via ‘Add CP’ unit 210. The OFDM symbols themselves are the ‘useful portion’, while overhead information such as CP is regarded in the art as non-useful information/portion. The remaining limitations were previously addressed and/or are readily apparent); and
forming the cyclic prefix (CP) by prepending to said each OFDM symbol a plurality of time-domain samples from the end of the useful portion (previously addressed. Also this limitation merely states the basic concept of a cyclic prefix in regards to OFDM modulation schemes (implemented after the IFFT operation but before the digital-to-analog converter (DAC)); which is applicable to the Kang reference as well as the IEEE 802.16m standard).
