In view of the above, having the system of D1 and then given the well-established teaching of D2, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention was made to modify the system of D1 as taught by D2. The motivation for doing so would have been to provide evaluate the time difference results improve improved IAB handling, in particular with respect to downlink timing of an IAB (child) node (D2, 003]). As per Claim 23, is the non-transitory computer readable medium (CRM) claim corresponding to the apparatus claim 22 that has been rejected above. Applicant attention is directed to the rejection of claim 22. Claim 23 is anticipated by CRM being performed by the apparatus above and therefore is rejected under the same rational as claim 22. Claim 8 is rejected under 35 U.S.C. 103 as being unpatentable over D1, in view of D2, and further in view of KIM et al. (U.S. Patent Application Publication No. 2018/0091267), (“D3”, hereinafter).

In view of the above, having the system of D1 and then given the well-established teaching of D3, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention was made to modify the system of D1 as taught by D3. The motivation for doing so would have been to provide an efficient scalable frame structure results improve aligning transmission symbols having the same cyclic prefix (CP) overhead in different subcarrier spacings with symbol levels (D3, 0009]). Claim 9 is rejected under 35 U.S.C. 103 as being unpatentable over D1, in view of D2, and further in view of Zhang et al. (U.S. Patent Application Publication No. 20130142106), (“D4”, hereinafter). As per Claim 9, D1 and D2 disclose the method according to claim 6, and D1 further discloses wherein the transmission timing comprises the time difference between the first timing and the second timing ([see, [0015], timing difference between receive timing (first timing) and transmission timing (second timing) at the relay node (first parent node)]).

In view of the above, having the system of D1 and then given the well-established teaching of D4, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention was made to modify the system of D1 as taught by D4. The motivation for doing so would have been to provide timing adjustment results improve the throughput of the system and expand the coverage of a network (D4, 0002-0003]). Claims 18-20 are rejected under 35 U.S.C. 103 as being unpatentable over D1, in view of D2, and further in view of Zhang et al.

However, D5 discloses wherein the number of advanced or lagged OFDM symbols of the third timing of the target node relative to the fourth timing of the target node ([see, [0037, 0045-0046], wherein the timing offset occurs at the OFDM symbol level within a subframe, OFDM symbols transmitted from the relay station may be offset either to lead or to lag the subframes and/or OFDM symbols received from the base station]), comprises: at least one of: a number of advanced or lagged OFDM symbols of the uplink transmit timing (UTT) of the target node relative to a timing advance of the target node ([see, [0037, 0045-0046, 0050], and Fig. 1B, 4-5, wherein the number of OFDM symbols, lag the OFDM symbols received from the base station 103, and RS 140 transmits either frame 450 or frame 470 to MS 117]); a number of advanced or lagged OFDM symbols of the UTT of the target node relative to the DTT of the target node; a number of advanced or lagged OFDM symbols of URT of the target node relative to DRT of the target node; a number of advanced or lagged OFDM symbols of the UTT of the target node relative to the URT of the target node; or a number of advanced or lagged OFDM symbols of the DTT of the target node relative to the DRT of the target node. In view of the above, having the system of D1 and then given the well-established teaching of D5, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention was made to modify the system of D1 as taught by D5. The motivation for doing so would have been to provide number of OFDM symbols within the relay wireless traffic between a base station of a wireless network results improved relay stations for use in a wireless network (D5, 0010]). As per Claim 19, D1 and D2 disclose the method according to claim 6, and D1 doesn’t appear explicitly disclose: further comprising: determining the number of advanced or lagged OFDM symbols of the third timing of the target node relative to the fourth timing of the target node according to a predefined manner; and the determining the number of advanced or lagged OFDM symbols of the third timing of the target node relative to the fourth timing of the target node according to the predefined manner comprises: determining a default value of the number of OFDM symbols according to a node physical distance between the first parent node and the target node.

In view of the above, having the system of D1 and then given the well-established teaching of D5, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention was made to modify the system of D1 as taught by D5. The motivation for doing so would have been to provide number of OFDM symbols within the relay wireless traffic between a base station of a wireless network results improved relay stations for use in a wireless network (D5, 0010]). As per Claim 20, D1 and D2 disclose the method according to claim 6, and D1 further discloses wherein the configuration signaling comprises physical-layer signaling, medium access control (MAC) layer signaling, radio resource control (RRC) signaling and/or Operation Administration and Maintenance (OAM) signaling ([see, [0012], the type of signaling used includes medium access control (MAC) signaling, RRC signaling disclosed]). D1 doesn’t appear explicitly disclose: further comprising: determining the number of advanced or lagged OFDM symbols of the third timing of the target node relative to the fourth timing of the target node according to configuration signaling. However, D5 discloses determining the number of advanced or lagged OFDM symbols (i.e., lag the OFDM symbols ) of the third timing of the target node ([see, [0044], the time offset between frames and subframes received from BS 103]) relative to the fourth timing of the target node according to the predefined manner ([see, [0044], the time offset between frames and subframes transmitted to MS 117]). In view of the above, having the system of D1 and then given the well-established teaching of D5, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention was made to modify the system of D1 as taught by D5. The motivation for doing so would have been to provide number of OFDM symbols within the relay wireless traffic between a base station of a wireless network results improved relay stations for use in a wireless network (D5, 0010]).
