Claim Rejections - 35 USC § 103
In the event the determination of the status of the application as subject to AIA 35
U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any
correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will
not be considered a new ground of rejection if the prior art relied upon, and the rationale
supporting the rejection, would be the same under either status.
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
he claimed invention pertains. Patentability shall not be negated by the manner
in which the invention was made.
The factual inquiries for establishing a background for determining obviousness
under 35 U.S.C. 103 are summarized as follows:
• Determining the scope and contents of the prior art.
• Ascertaining the differences between the prior art and the claims at issue.
• Resolving the level of ordinary skill in the pertinent art.
• Considering objective evidence present in the application indicating
• obviousness or nonobviousness.
This application currently names joint inventors. In considering patentability of the
claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any
evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to
point out the inventor and effective filing dates of each claim that was not commonly
owned as of the effective filing date of the later invention in order for the examiner to
consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2)
prior art against the later invention.

Regarding Claim 4,
‘The UE of claim 1’ (disclosed above),
LIM discloses, bundling size can be determined based on resource allocation type. Disclosure provides various resource allocation type. And, multiple active bandwidth configured includes PRB contiguous or dis-contiguous. Dis-contiguous RB can be uniformly allocated in frequency domain.
And, didn’t disclose, ‘wherein the section extension message indicates that the UE is not scheduled with non-contiguous PRBs.’
Haghighat in the same field of endeavor discloses, schedule RBs may or may not be contiguous Col. 21 [0043].

Further includes, MIMO precoders: narrow-band, mid-band, and wide-band. plurality of subbands can have a respective plurality of bandwidths and subbands includes contiguous and non-contiguous. FIG. 4 is a graph illustrating a capacity comparison of adaptive CDD precoding with other precoding mechanisms. The comparison is based on capacity estimates of a 4×4 MIMO system.
A method for the terminal uses a band that is a scheduled bandwidth comprises: adjacent, contiguous and non-contiguous. Disclosure claim 1, 3 and 4.
Further, a transmit precoding matrix includes a set of subbands and uses adjacent subbands based on uniform structured pattern on scheduled transmission as illustrated Fig. 23.

Would be obvious to indicate when scheduling specific to the contiguous that is not being schedule for the non-contiguous. LIM motive to use beam id for specific PRB set [0133-0141] for beamforming scheme. And, to increase transmission bandwidth that is very crucial for the bandwidth optimization. Haghighat complements the motive to further optimize MIMO performance Col. 23 [0017] can increase the system bandwidth and utilize the precoding resource-block (PRG) more effectively.
