Office Action

§103
DETAILED ACTION This communication is in response to applicant’s response filed under 37 C.F.R. §1.111 in response to a non-final office action. Claims 21 have been amended; Claims 20 have been canceled. Claims 1-19 and 21 are subject to examination. Response to Arguments Applicant's arguments filed July 29, 2026, have been fully considered but they are not persuasive for the following reasons: Applicant’s Argument: The applicant argues, on page 9 in substance that "Applicant respectfully submits that CHA and ROSA do not disclose each and every feature recited in claim 1. For example, CHA and ROSA, taken alone or in any reasonable combination, do not disclose at least "receiv[ing], from a network entity having a plurality of antenna panels, information identifying, for each antenna panel of the plurality of antenna panels, a quantity of demodulation reference signal (DMRS) sequences for a message type A (msgA) physical uplink shared channel (PUSCH) transmission of a two-step random access channel procedure," as recited in claim 1. The Office Action relies on paragraph [0365] of CHA for allegedly disclosing receiving from a network entity having a plurality of antenna panels, information identifying the plurality of antenna panels. " Examiner’s Response: The examiner respectfully disagrees. Cha teaches identifying a technical problem to provide a method and device for transmitting a reference signal by a UE/base station equipped with a multi-antenna panel and initializing a reference signal sequence used to generate the reference signal based on the panel identification information and transmitting the reference signal to the base station based on the initialized reference signal sequence. Cha teaches that a UE/base station equipped with a multi-antenna panel may transmit a reference signal signaling between a base station and a UE and operations of the base station and the UE for effective wireless communication between the base station and UE equipped with one or more multiple transmission/reception antenna panels [0172, 0178-0179] and teaches ‘panel’ of the base station/UE may be used in the same meaning as the ‘antenna panel’ and the ‘transmission/reception panel’ of the base station/UE and panel” interpreted in various manners, as a “UE antenna element group,” “UE antenna port group,” “or “UE logical antenna group” ... Antenna panel may mean that several antenna elements are mounted on one physical panel. Further, CHA teaches [0170] that the base station may allocate different DMRS resources to different UEs sharing PUSCH resource, [0177] “uplink resource (or resource group)” may be interchangeably interpreted/applied as PRACH resource. and Fig. 14. a first wireless device 1410 and a second wireless device 1420 may transmit radio signals {the first wireless device 1410 and the second wireless device 1420} may correspond to {the wireless device 1410x and the BS 1420} and/or {the wireless device 1410x and the wireless device 1410x} of FIG. 13. Therefore examiner is construing that the UE and the bases station shows plurality of antenna 108 and 208 and using uplink resource interchangeably PRACH resource to allocate DMRS. Therefore, combining Rosa, [0041] the 2-step RACH procedure, in particular, the channel structure for msgA, including the mapping between the PRACH preamble and the time-frequency resources of PUSCH in msgA and demodulation reference signal (DMRS). However, claim 1 merely recites ...receiving from a network entity having plurality of antenna panels... Applicant’s Argument: The applicant argues, on page 11 in substance that "ROSA does not cure these deficiencies of CHA. Although ROSA describes MsgA PUSCH transmissions and may signal a number of DMRS for beam refinement or a number of UE transmitter-beam-refining configurations, ROSA does not identify that number for each antenna panel of a network entity. See, for example, ROSA, paragraphs [0051], [0060], and [0067]-[0076]. In particular, ROSA's values N and M relate to UE transmitter-beam configurations for transmission of the DMRS portion of MsgA. ROSA's disclosure that DMRS sequences or ports and associated resources may be grouped by time and frequency does not identify a quantity of DMRS sequences for each antenna panel of a network entity. Nor does ROSA's disclosure of a device having an array of antennas establish the recited per-panel relationship. ROSA therefore does not disclose that a network entity having a plurality of antenna panels transmits information identifying, for each antenna panel of the network entity, a quantity of DMRS sequences. ROSA also does not disclose configuring the transmitted DMRS sequences based on respective quantities identified for the antenna panels of the network entity. Examiner’s Response: The examiner respectfully disagrees. Rosa identifies that in Fig. 15 transceivers 1513 and 1523 of network entity 1510 and user equipment 1520, may have many antennas such as an array of antennas configured for multiple input multiple output (MIMO) communications, or multiple antennas for multiple radio access technologies. Therefore combining CHA as the above response generating the reference signal based on the panel identification information and transmitting the reference signal to the base station based on the initialized reference signal sequence along with Rosa a quantity of DMRS sequence for a message type A (msgA) teaches array of antennas configured for multiple input multiple output (MIMO) communications, or multiple antennas for multiple radio access technologies and be configured both for transmission and reception. However, claim 1 merely recites ... identifying, for each antenna panel of the plurality of antenna panels, a quantity of demodulation reference signal (DMRS) sequences for a message type A (msgA) physical uplink shared channel (PUSCH) transmission of a two-step random access channel procedure... Regarding all other arguments presented by applicant, the arguments are substantially the same as those which have already been addressed above and in the interest of brevity; the examiner directs the applicant to those responses above. 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 (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 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 claimed 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.

Claim 11 is rejected under 35 U.S.C. 103 as being unpatentable over Cha-Rosa as applied to claim 1 above, and further in view of Seo et al. (Seo hereafter) (US 20130242853 A1). Regarding claim 11 Cha-Rosa teaches, The UE of claim 1, Cha-Rosa fails to explicitly teach, wherein the DMRS scrambling identifier is configured on a per antenna port basis via a system information or radio resource control transmission. However, in the same field of endeavor Seo teaches,wherein the DMRS scrambling identifier is configured on a per antenna port basis via a system information or radio resource control transmission (Seo; [0184] FIG. 14 is a flowchart indicating a method for a base station to configure a scramble ID and/or an antenna port to a user equipment according to one embodiment of the present invention.[0185] Referring to FIG. 14, the base station transmits the antenna port information and the scramble ID to a user equipment). It would have been obvious to one of ordinary skilled in the art before the effective filing date to create the invention of Cha-Rosa to include the above recited limitations as taught by Seo in order to configure a scramble ID and an antenna port to transmit the PDSCH (Seo; [0188]). Conclusion THIS ACTION IS MADE FINAL. Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a).
