Office Action

§102
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Information Disclosure Statement As required by M.P.E.P. 609(c), the Applicant's submissions of the Information Disclosure Statement is acknowledged by the examiner and the cited references have been considered in the examination of the claims now pending. As required by M.P.E.P. 609 C(2), a copy of the PTOL-1449 initialed and dated by the examiner is attached to the instant office action. Applicant’s Information Disclosure Statement has been received, entered into the record, and considered. See attached form PTO-1449. Claims 1-2 are canceled. Claims 3-6 are pending for examination, infra. Claim Rejections - 35 USC § 102 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 (i.e., changing from AIA to pre-AIA ) 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 the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. Claims 3-6 are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Jongeonb Baek et al., (US Publication No. 2023/0101824 A1 and Baek hereinafter). Regarding Claims 3 and 6, Baek teaches a method performed by a terminal, the method comprising: receiving, by the terminal from a base station (i.e., sharing power and resources for on-demand sidelink positioning in a new radio-vehicle to everything (NR-V2X) communication system, and an apparatus therefor. A method by which a terminal shares power in a new radio-vehicle to everything (NR-V2X) communication system, according to one aspect, may comprise the steps of: configuring, in a physical sidelink feedback channel (PSFCH), transmission resources for HARQ-ACK feedback information (HFI) associated with an NR-V2X service and transmission resources for a positioning reference signal (PRS) associated with sidelink positioning) (Abstract), a specific system information block (SIB) (i.e., V2X…. NR) Para [0004]; [0025] (Examiner asserts that system information block is in radio technologies, such as V2X, NR, for example) and (i.e., (system information that the UE needs to first know before transmitting and receiving an SL signal. For example, the basic information may include information related to the SLSSs, duplex mode (DM) information, time division duplex (TDD) UL/DL (UL/DL) configuration information, resource pool-related information, information about the type of an application related to the SLSSs, subframe offset information, broadcast information) Para [0105], wherein: the specific SIB comprises one or more sets of resource pool parameters (i.e., positioning data dedicated resource pool structures for positioning data transmission, which are different from conventional resources) Para [0023]; and each set of the one or more sets of resource pool parameters (i.e., specific resources in a resource pool which is a set of resources. UE1 may then transmit an SL signal in the resource unit. For example, UE2, which is a receiving UE, may be configured with the resource pool in which UE1 may transmit a signal, and detect the signal from UE1 in the resource pool.) Para [0113] comprises a bitmap (i.e. bitmap) para [0380] related to Sidelink Positioning Reference Signal (SL-PRS) (i.e., transmitting a positioning reference signal (PRS) for sidelink positioning through a physical sidelink feedback channel (PSFCH) in an NR-V2X system and proposes a PRS transmission method using a PRS transmission structure preconfigured on the PSFCH and the PSFCH in order to effectively use a PSFCH-PRS resource (a PSFCH resource for PRS)) Para [0189] resource pool during a Direct Frame Number (DFN) cycle (i.e., number of symbols per slot, the number of slots per frame, and the number of slots per subframe according to an SCS in the ECP case ) Para [0092-0093]; transmitting, by the terminal to the base station, a specific uplink message Para [0324], wherein the specific uplink message (i.e., transmission and uplink) Para [0220] comprises: a parameter related to sidelink positioning reception interest (i.e., serving gNB of a target UE to obtain a location measurement of the UE. For positioning the target UE, the LMF may determine a positioning method based on a location service (LCS) client type, a QoS requirement, UE positioning capabilities, gNB positioning capabilities, and ng-eNB positioning capabilities, and apply the positioning) Para [0172] dand Para [0427]; a parameter related to sidelink destination identity (i.e., radio access network (NG-RAN) may include a next generation Node B (gNB) and/or an eNB, which provides user-plane and control-plane protocol termination to a UE. the NG-RAN is shown as including only gNBs, by way of example. A gNB and an eNB are connected to each other via an Xn interface. The gNB and the eNB are connected to a 5G core network (5GC) via an NG interface. More specifically, the gNB and the eNB are connected to an access and mobility management function) Para [0088]; a parameter related to delay of SL-PRS (i.e. packet delay) Para [0136]; and a parameter related to bandwidth of SL-PRS (i.e., bandwidth) Para [0094] and [0099]; and performing, by the terminal (i.e., s uplink/downlink communication 150a, sidelink communication 150b (or, D2D communication), or inter BS communication (e.g. relay, Integrated Access Backhaul (IAB)). The wireless devices and the BSs/the wireless devices may transmit/receive radio signals to/from each other through the wireless communication/connections) Para [0421], SL-PRS operation based on one or more SL-PRS resource pools configured by the one or more sets of resource pool parameters (i.e., resource pool structures for positioning data transmission, which are different from resources for conventional V2X data transmission, and management methods therefor. The management of independent dedicated resource pools for positioning data may satisfy positioning service requirements, which need to provide location information through fast positioning. However, when there is no positioning data transmission, the management of dedicated resource pools for positioning data may reduce the efficiency of V2X data transmission and the overall efficiency of sidelink resource use) Para [0315]. Regarding Claim 4, Baek teaches wherein the specific SIB further comprises: a field indicating the number of symbols used for sidelink in a slot (i.e., perform sidelink on-demand positioning in an NR-V2X communication system. The UE may include: a radio frequency (RF) transceiver; and a processor connected to the RF transceiver. The processor may be configured to: configure a resource for transmitting a PRS related to the sidelink positioning on a PSFCH; when there is a request for simultaneous transmission of the PRS and HFI related to NR-V2X services, allocate power available) Para [0035] without sidelink synchronization signal block (SSB) (i.e., NR system, different OFDM(A) numerologies (e.g., SCSs, CP lengths, and so on) may be configured for a plurality of cells aggregated for one UE. Accordingly, the (absolute time) duration of a time resource including the same number of symbols (e.g., a subframe, slot, or TTI) (collectively referred to as a time unit (TU) for convenience) may be configured to be different for the aggregated cells. In NR, various numerologies or SCSs may be supported to support various 5G services) Para [0094]; and a field indicating a starting symbol used for sidelink in the slot without sidelink SSB (i.e., perform sidelink on-demand positioning in an NR-V2X communication system. The UE may include: a radio frequency (RF) transceiver; and a processor connected to the RF transceiver. The processor may be configured to: configure a resource for transmitting a PRS related to the sidelink positioning on a PSFCH; when there is a request for simultaneous transmission of the PRS and HFI related to NR-V2X services, allocate power available) Para [0090-0092] see also (i.e., sidelink-synchronization signal block (S-SSB)) supporting periodic transmission. The S-SSB may have the same numerology (i.e., SCS and CP length) as a physical sidelink control channel (PSCCH)/physical sidelink shared channel (PSSCH) in a carrier, and the transmission bandwidth of the S-SSB may be within a (pre)configured SL BWP. For example, the bandwidth of the S-SSB may be 11 RBs. For example, the PSBCH may span 11 RBs. The frequency position of the S-SSB may be (pre)set. Therefore, the UE does not need to perform hypothesis detection in a frequency to discover the S-SSB in the carrier) Para [106]. Regarding Claim 5, Baek teaches wherein the specific SIB further comprises a subcarrier spacing parameter indicating a specific subcarrier spacing for one or more SL-PRS (i.e., PSFCH-PRS, on-demand positioning may be considered, and 1) a transmission structure between a request PRS and a response PRS, 2) a time gap between a request PRS transmission time and a response PRS reception time (request PRS-response PRS time gap), 3) PRS ID allocation for request PRS and response PRS transmission) Para [0910]-[0194] resource pools (i.e., dedicated resource pool structures) Para [0315] that are configured by the one or more sets of resource pool parameters (i.e., resource pool used for a transmitting UE to transmit user data. When an SA is multiplexed with SL data in the same resource unit, for transmission, only the SL data channel except for SA information may be transmitted in a resource pool for the SL data channel. In other words, REs used to transmit the SA information in an individual resource unit in an SA resource pool may still be used to transmit SL data in the resource pool of the SL data channel.) Para [0121]. Pertinent Prior Art The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Baek et al., (US Patent Publication No. 20230101824 A1), “METHOD FOR SHARING POWER AND RESOURCES FOR SIDELINK POSITIONING, AND APPARATUS THEREFOR” (March 30, 2023), discloses sharing power and resources for on-demand sidelink positioning in a new radio-vehicle to everything (NR-V2X) communication system, and an apparatus therefor. The terminal shares power in a new radio-vehicle to everything (NR-V2X) communication system may comprise configuring, in a physical sidelink feedback channel (PSFCH), transmission resources for HARQ-ACK feedback information (HFI) associated with an NR-V2X service and transmission resources for a positioning reference signal (PRS) associated with sidelink positioning.
