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.

Having received the NACK signal, the transmitter may retransmit the packet].
Before the effective filing date it would have been obvious to one of ordinary skill in the art to combine the teachings of Pi, Khan, and Nasiri because to improve the channel estimation quality is to use iterative demodulation/decoding and channel estimation. [Nairi par 0016]
4. Claim(s) 10, 20 is/are rejected under 35 U.S.C. 103 as being unpatentable over Pi et al. (U.S. Pub No. 2009/0254790 A1) in view of Khan (U.S. Pub No. 2010/0091905 A1) in further view of BALASUBRAMANIAN et al. (U.S. Pub No. 2021/0167899 A1).
10, Pi and Khan defines the method of claim 6, Pi and Khan fail to show wherein the plurality of bits selected from across two or more code blocks of the packet is selected using a set of interleavers associated with a redundancy version (RV) index.
In an analogous art BALASUBRAMANIAN show wherein the plurality of bits selected from across two or more code blocks of the packet is selected using a set of interleavers associated with a redundancy version (RV) index [par 0151, Similar numbered code block groups in TB.sub.1 1205 and TB.sub.2 1240 are used to generate cross redundancy versions. For example, cross parity bits produced jointly using CBG.sup.1.sub.3 1230 and CBG.sup.2.sub.3 1260 yields cross redundancy versions: (cRV1).sup.12.sub.3, (cRV2).sup.12.sub.3, and (cRV3).sup.12.sub.3. The procedure for generating cross redundancy versions between CBGs belonging to two different transport blocks is similar to the encoding procedure depicted in FIG. 8, with the transport blocks TB.sub.1 and TB.sub.2 replaced by code block groups CBG.sup.k.sub.m. That is, an interleaver may be used to produce a concatenated code block group, and the concatenated code block group may be segmented into code blocks, and encoding is performed per code block in a typical manner].
Before the effective filing date it would have been obvious to one of ordinary skill in the art to combine the teachings of Pi, Khan, and BALASUBRAMANIAN because this provides methods and apparatuses that optimize resource usage for HARQ stop-and-wait procedure over an NTN link are needed.
20, Pi and Khan reveal the apparatus of claim 16, Pi and Khan fail to show wherein the plurality of bits selected from across two or more code blocks of the packet is selected using a set of interleavers associated with a redundancy version (RV) index.

Before the effective filing date it would have been obvious to one of ordinary skill in the art to combine the teachings of Pi, Khan, and BALASUBRAMANIAN because this provodes methods and apparatuses that optimize resource usage for HARQ stop-and-wait procedure over an NTN link are needed.
