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 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 20claimed 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. Claims 1 -5 and 11-15 are rejected under 35 U.S.C. 103 as being unpatentable over Lee et al. (US 2018/0227848, hereinafter Lee) in view of Namboodiri et al. (US 2020/287672, hereinafter Namboodiri). Regarding claim 1, Lee discloses a method implemented by a wireless transmit/receive unit (WTRU) (610/620 of fig. 6) using a narrowband companion air interface (NB-CAI) that supports a wideband air interface (WB-AI) (para 0076; 0092-0093; transmitting wideband signals - t he base station may allocate the second portion of bandwidth for transmission of TRSs. The base station may transmit a TRS over every subcarrier within the second portion of bandwidth. A UE may receive TRS transmission and may perform fine frequency or time tracking based on the received TRSs. In some cases, a narrowband carrier may utilize a full TRS implementation) , wherein the NB- CAI and WB-AI operate over a same channel (para 0076 and 0093 ; 0095 – narrowband and wideband operate on the same channel- second portion of the same bandwidth for narrowband carrier ) , the method comprising: sending, via the NB-CAI to a network node (Para 0072; 0093; 0170; 0186; a set of resources for a TRS periodically transmitted by the base station in a data region of a first TTI, the TRS comprising a plurality of sub-patterns for a set of sub-carriers of a carrier for the UE for a set of symbol periods in the first TTI ; the base station communications manager may coordinate scheduling for transmissions to UEs for various interference mitigation techniques such as beamforming or joint transmission. In some examples, base station communications manager may provide an X2 interface within an LTE/LTE-A – narrowband signaling for control/resource request ) , a scheduling request for a frequency convergence reference signal (FCRS) over the WB-AI ( According to applicant’s specs 0167 – other reference signals can be used as FCRS e.g. tracking signals; para 0007; 0029; 0080 – a UE may wake up from an idle state and enter a connected state with base station within a network.

The synchronization block may include one or more PBCHs, a PSS, and an SSS. The synchronization block may span a set of symbol periods in the time domain, and a portion of a bandwidth in the frequency domain. For example, the synchronization block may span four symbol periods in the time domain, and a bandwidth spanning six resource blocks (RBs) in the frequency domain. UE upon connecting with base station, may receive the synchronization block and may perform configuration processes based on information contained within the synchronization block. In some cases, UE may perform time or frequency tracking based on a synchronization signal within the received synchronization block) ; receiving, via the WB-AI, periodic FCRS s from the network node based on the received scheduling response (para 0007; 0028; 0053; periodic transmission of TRS on the determined set of resources) . Lee does not explicitly disclose sending, via the NB-CAI, a request to the network node to change a rate of FCRS transmissions, wherein the request to change a rate of FCRS transmissions is based on a convergence indication. In an analogous art, Namboodiri discloses sending, via the NB-CAI, a request to the network node to change a rate of FCRS transmissions (para 0007; corrections on results of a received and initial automatic gain control corrected signal) , wherein the request to change a rate of FCRS transmissions is based on a convergence indication (Para 013 1 ; after the coarse frequency correction, the residual frequency error is much less than this). It would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to modify Lee ’s method/system by having Namboodiri ’s disclosure in order to improve resource allocation by dynamically addressing the system requirements . Regarding claim 11, Lee discloses a wireless transmit/receive unit (WTRU) (610/620 of fig. 6) configured to use a narrowband companion air interface (NB-CAI) that supports a wideband air interface (WB-AI) (para 0076; 0092-0093; transmitting wideband signals - t he base station may allocate the second portion of bandwidth for transmission of TRSs.

For example, the synchronization block may span four symbol periods in the time domain, and a bandwidth spanning six resource blocks (RBs) in the frequency domain. UE upon connecting with base station, may receive the synchronization block and may perform configuration processes based on information contained within the synchronization block. In some cases, UE may perform time or frequency tracking based on a synchronization signal within the received synchronization block) ; the transceiver is further configured to receiv e , via the WB-AI, periodic FCRSs from the network node based on the received scheduling response (para 0007; 0028; 0053; periodic transmission of TRS on the determined set of resources). Lee does not explicitly disclose that the transceiver is further configured to send, via the NB-CAI, a request to the network node to change a rate of FCRS transmissions, wherein the request to change a rate of FCRS transmissions is based on a convergence indication. In an analogous art, Namboodiri discloses that the transceiver is further configured to send , via the NB-CAI, a request to the network node to change a rate of FCRS transmissions (para 0007; corrections on results of a received and initial automatic gain control corrected signal), wherein the request to change a rate of FCRS transmissions is based on a convergence indication (Para 0131; after the coarse frequency correction, the residual frequency error is much less than this). It would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to modify Lee’s method/system by having Namboodiri’s disclosure in order to improve resource allocation by dynamically addressing the system requirements. Regarding claims 2 and 12, Lee discloses wherein the FCRS scheduling response comprises at least one of: FCRS sequence information, a periodicity, an initial time offset, frequency domain allocation information, and or beam information (para 0068; beamforming; 0080; frequency domain allocation; 0084 – periodicity) .

It would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to modify Lee’s method/system by having Namboodiri’s disclosure in order to improve resource allocation by dynamically addressing the system requirements. Regarding claims 5 and 15, Lee discloses performing measurements on the received periodic FCRSs (para 0053 ; 0060 ; t he UE may rely on continuous or periodic transmission of reference signals to obtain fine time and frequency tracking measurements ) . Claims 10 and 20 are rejected under 35 U.S.C. 103 as being unpatentable over Lee/Namboodiri in view fo Maamari et al. (US 2019/0356364, hereinafter Maamari ). Regarding claims 10 and 20, Lee/Namboodiri does not explicitly disclose wherein the convergence indication is based on a convergence threshold. In an analogous art, Maamari discloses wherein the convergence indication is based on a convergence threshold (para 0077 and 0098). It would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to modify Lee /Namboodiri ’s method/system by having Maamari ’s disclosure in order to reduce communications overhead to improve the utilization of system resources.
