(See Ren fig. 2; Doppler and delay dimension of each subblock wherein the index pattern indicates a non-zero pattern in that some blocks are assigned (e.g. non-zero) and some are not (e.g. zero); inactive subcarriers are set to zero; see pg. 3) The motivation being to utilize the latest multiplexing schemes which may be a more efficient usage of limited wireless resources with certain characteristics which lend themselves to these schemes and further to achieve better BER performance (See Ren abstract) and further to provide reliable data transmission in high mobility environments (See Ren Intro). wherein the index modulation pattern are based at least in part on one or more of: the PAPR requirement or a data requirement, (See Gong para. 124-125; modulation order (e.g. modulation pattern) of resource selected based upon type of data; para. 94; resource selected based upon requirements of apparatus; para. 25;) The motivation being to reduce distortion and further to allow for less battery usage and complexity at receiver side and further to allow for less capable devices to receive and decode the signal successfully and further to increase bandwidth and further to increase detection performance. Zhang in view of Ren in view of Gong does not explicitly disclose wherein the subblock size depends upon the modulation order. However, Qaraqe does disclose wherein the subblock size is based at least in part on a modulation order. (See Qaraqe para. 52; subblock size depends on modulation order; see also para. 4) Therefore it would have been obvious to one of ordinary skill in the art before the effective filing date to modify the apparatus of Zhang in view of Ren in view of Gong to include the teaching of wherein the subblock size is based at least in part on a modulation order of Qaraqe with the motivation being to balance spectral efficiency and error rate performance and further in order to maintain acceptable performance (inverse relationship; higher modulation orders require smaller subblocks; while lower modulation orders can use larger subblocks) and further to balance spectral efficiency vs energy efficiency and further to improve error performance. Claim 16 is rejected under 35 U.S.C. 103 as being unpatentable over Zhang (2015/0382336), and further in view of Ren (Ren, Huarong, et. al. “Orthogonal Time-Frequency Space with Improved Index Modulation” 15th International Conference on Signal Processing and Communication Systems; 2021.) and further in view of Gong (2024/0214170; Foreign priority 27 Aug 2021) and further in view of Ma (2023/0319708).

Zhang in view of Ren in view of Gong does not explicitly disclose indicating a maximum block size supported by UE. However, Ma does disclose indicating a maximum block size supported by UE. (See Ma para. 28, para. 36; para. 332) Therefore it would have been obvious to one of ordinary skill in the art before the effective filing date to modify the apparatus of Zhang in view of Ren in view of Gong to include the teaching of indicating a maximum block size supported by UE of Ma with the motivation being indicating a maximum block size supported by UE of Ma with the motivation being to reduce delay in transmission and further to match UE ability with network ability to maximize wireless resources and further to reduce wasted wireless resources and battery power and further to maximize throughput and further to meet delay and error goals. Claim 17 is rejected under 35 U.S.C. 103 as being unpatentable over Zhang (2015/0382336), and further in view of Ren (Ren, Huarong, et. al. “Orthogonal Time-Frequency Space with Improved Index Modulation” 15th International Conference on Signal Processing and Communication Systems; 2021.) and further in view of Gong (2024/0214170; Foreign priority 27 Aug 2021) and further in view of Manolakos (2018/0115382).

(See Manolakos fig. 14 and associated paragraphs; UE obtains first and second reference signal value and determines the data portion of the field based upon these two reference signal values to determine multiplexing pattern for data; see also fig. 15, fig. 3 and associated paragraphs) Therefore it would have been obvious to one of ordinary skill in the art before the effective filing date to modify the method of Zhang in view of Ren in view of Gong to include the teaching of wherein a data modulation pattern, wherein the parameters are received via a reference signal wherein the reference signal has its own parameters which are stored by the UE and used to detect the reference signal of Manolakos with the motivation being to reduce control signaling and further to reduce delay in accessing a network and further to reduce jitter and further to maximize limited wireless resources.
