As to claim 10:
Abdelghaffar et al. discloses:
A terminal comprising:
a receiver that receives a configuration of a demodulation reference signal (DMRS) using a frequency domain orthogonal cover code (FD-OCC) having a length of 4, for a physical uplink shared channel (PUSCH); and
(“For example, a UE 115 of the wireless communications system 100 may receive control signaling (e.g., RRC signaling, MAC-CE signaling, DCI signaling) which indicates an FD-OCC sequence length value for wireless communications with the network. The FD-OCC sequence length value may be 4, 6, 8, etc. (e.g., N=4, 6, 8). The UE may then receive an indication of an antenna port field value, and may determine which one or more orthogonal DMRS ports are to be used for transmitting DMRSs based on the indicated FD-OCC sequence length value and the antenna port value. In some aspects, the UE 115 may be configured to identify a set of cyclic shift (CS) sequence values, a Walsh sequence, or both, based on the indicated antenna port field value and the indicated sequence length value, and may determine one or more DMRS ports at the UE 115 which are to be used based on the identified CS values and/or Walsh sequence. In some aspects, a quantity of CS values within the set of CS sequence values and/or the length of the Walsh sequence may be based on the sequence length.”; Abdelghaffar et al.; 0133)
(“…For example, the UE 115 may transmit uplink signals, such as uplink control signals or uplink data signals (e.g., physical uplink shared channel (PUSCH) transmissions), to the base station 105 using the communication link 205 and the base station 105 may transmit downlink signals, such as downlink control signals or downlink data signals, to the UE 115 using the communication link 205.”; Abdelghaffar et al.; 0087)
(“…The wireless communications system 200 may enable techniques for increasing a sequence length of FD-OCCs supported by the wireless communications system, thereby increasing a quantity of available orthogonal DMRS ports for supporting a higher number of spatial layers for uplink transmissions. In particular, the wireless communications system 100 may support techniques for signaling higher-order FD-OCCs (e.g., having a sequence length N>2), and configurations for indicating antenna port values for higher-quantities of supported DMRS ports.”; Abdelghaffar et al.; 0132)

Referring to the DMRS pattern 310, the first four ports/columns (e.g., ports/columns 0-3) may be the same as the legacy port mapping for FD-OCC length two (e.g., same for N=2).

Abdelghaffar et al. as described above does not explicitly teach:
However, Jacobsson et al. further teaches a FD-OCC complex-code/cyclic shifts capability which includes:
(“In particular embodiments, the FD-OCC comprises a real-valued code (e.g., Hadamard) or a complex-valued code (e.g., cyclic shifts).”; Jacobsson et al.; 0031)
(“In some embodiments, the FD-OCC code is of length 8 or longer. In particular embodiments, the FD-OCC contains codewords that correspond to cyclic shifts that are integer multiples of 360°/L.sub.C, where L.sub.C is the length of the FD-OCC.”; Jacobsson et al.; 0079)
(where
“FD-OCC comprises…complex-valued code (e.g. cyclic shifts)” maps to “, “cyclic shifts that are integer multiples of 360°/L.sub.C, where L.sub.C is the length of the FD-OCC” maps to “using a cyclic shift {0, π, π/2, 3π/2}”
Jacobsson et al. teaches a FD-OCC comprising complex-valued code associated with cyclic shifts, where the FD-OCC contains codewords with cyclic shifts that are integer multiples of 360 degrees divided by the length of the FD-OCC.
Thus, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to implement the FD-OCC complex-code/cyclic shifts capability of Jacobsson et al. into Abdelghaffar et al. By modifying the processing/communications of Abdelghaffar et al. to include the FD-OCC complex-code/cyclic shifts capability as taught by the processing/communications of Jacobsson et al., the benefits of improved communication (Abdelghaffar et al.; 0005) with improved OTT (Jacobsson et al.; 0190) are achieved.

However, Jacobsson et al. further teaches a FD-OCC complex-code/cyclic shifts capability which includes:
(“In particular embodiments, the FD-OCC comprises a real-valued code (e.g., Hadamard) or a complex-valued code (e.g., cyclic shifts).”; Jacobsson et al.; 0031)
(“In some embodiments, the FD-OCC code is of length 8 or longer. In particular embodiments, the FD-OCC contains codewords that correspond to cyclic shifts that are integer multiples of 360°/L.sub.C, where L.sub.C is the length of the FD-OCC.”; Jacobsson et al.; 0079)
(where
“FD-OCC comprises…complex-valued code (e.g. cyclic shifts)” maps to “, “cyclic shifts that are integer multiples of 360°/L.sub.C, where L.sub.C is the length of the FD-OCC” maps to “using a cyclic shift {0, π, π/2, 3π/2}”
Jacobsson et al. teaches a FD-OCC comprising complex-valued code associated with cyclic shifts, where the FD-OCC contains codewords with cyclic shifts that are integer multiples of 360 degrees divided by the length of the FD-OCC.
Thus, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to implement the FD-OCC complex-code/cyclic shifts capability of Jacobsson et al. into Abdelghaffar et al. By modifying the processing/communications of Abdelghaffar et al. to include the FD-OCC complex-code/cyclic shifts capability as taught by the processing/communications of Jacobsson et al., the benefits of improved communication (Abdelghaffar et al.; 0005) with improved OTT (Jacobsson et al.; 0190) are achieved.
As to claim 14:
Abdelghaffar et al. discloses:
A system comprising a terminal and a base station, wherein
the terminal comprises:
a receiver that receives a configuration of a demodulation reference signal (DMRS)
using a frequency domain orthogonal cover code (FD-OCC) having a length of 4, for a physical uplink shared channel (PUSCH); and
a transmitter that transmits the configuration to the terminal; and
(“For example, a UE 115 of the wireless communications system 100 may receive control signaling (e.g., RRC signaling, MAC-CE signaling, DCI signaling) which indicates an FD-OCC sequence length value for wireless communications with the network. The FD-OCC sequence length value may be 4, 6, 8, etc. (e.g., N=4, 6, 8). The UE may then receive an indication of an antenna port field value, and may determine which one or more orthogonal DMRS ports are to be used for transmitting DMRSs based on the indicated FD-OCC sequence length value and the antenna port value. In some aspects, the UE 115 may be configured to identify a set of cyclic shift (CS) sequence values, a Walsh sequence, or both, based on the indicated antenna port field value and the indicated sequence length value, and may determine one or more DMRS ports at the UE 115 which are to be used based on the identified CS values and/or Walsh sequence. In some aspects, a quantity of CS values within the set of CS sequence values and/or the length of the Walsh sequence may be based on the sequence length.”; Abdelghaffar et al.; 0133)
(“…For example, the UE 115 may transmit uplink signals, such as uplink control signals or uplink data signals (e.g., physical uplink shared channel (PUSCH) transmissions), to the base station 105 using the communication link 205 and the base station 105 may transmit downlink signals, such as downlink control signals or downlink data signals, to the UE 115 using the communication link 205.”; Abdelghaffar et al.; 0087)
(“…The wireless communications system 200 may enable techniques for increasing a sequence length of FD-OCCs supported by the wireless communications system, thereby increasing a quantity of available orthogonal DMRS ports for supporting a higher number of spatial layers for uplink transmissions. In particular, the wireless communications system 100 may support techniques for signaling higher-order FD-OCCs (e.g., having a sequence length N>2), and configurations for indicating antenna port values for higher-quantities of supported DMRS ports.”; Abdelghaffar et al.; 0132)
(where
See FIG. 9 for “receiver”
“a UE 115 of the wireless communications system 100 may receive control signaling (e.g., RRC signaling, MAC-CE signaling, DCI signaling) which indicates an FD-OCC sequence length value for wireless communications with the network.

a processor that controls, based on the configuration, reception of the DMRS,
(“The DMRS port mapping configuration 300 for a single symbol for CS-based sequence length four (e.g., N=4), type-1 (8 DMRS ports in total) may be illustrated via the phase shift configuration 305 and the DMRS pattern 310. Referring to the DMRS pattern 310, the first four ports/columns (e.g., ports/columns 0-3) may be the same as the legacy port mapping for FD-OCC length two (e.g., same for N=2). As such, techniques described herein may enable new port mappings which are illustrated in the last four ports/columns (e.g., ports/columns 8-11) of the DMRS pattern 310. Moreover, the DMRS pattern 310 may be scalable to any N.”; Abdelghaffar et al.; 0148)

Abdelghaffar et al. teaches configuring a UE for FD-OCC with sequence length value of 4 and configuring DMRS ports for transmitting DMRSs based on the configured sequence length value, where the UE is configured with DMRS port mapping associated with a DMRS pattern where the FD-OCC is associated with Walsh sequences.
Abdelghaffar et al. as described above does not explicitly teach:
