Office Action

§103
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 . 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. Patentability shall not be negated by the manner in which the invention was made. Claims 1, 4, 9, 16, 18 and 20 are rejected under 35 U.S.C. 103 as being unpatentable over Xiang, Zhengzheng et al. (US 20200322032 A1, hereinafter referred to as Xiang) in view of Deenoo, Yugeswar et al. (US 20160337916 A1, hereinafter referred to as Deenoo-916). Regarding claim 1, Xiang teaches: sending first control information by using a first transmission beam (Xiang discloses sending sidelink control information (SCI) for beam training. See paragraph [0007]). wherein the first control information comprises resource location information of a first resource (Xiang discloses that the SCI includes time-frequency resource information and a resource identifier for a reference signal. See paragraph [0009]). and sending a first reference signal on the first resource by using M transmission beams, wherein M is a positive integer (Xiang discloses sending a reference signal using a plurality of narrow beams. See paragraph [0046]). and the first transmission beam covers each of the M transmission beams (Xiang discloses that each wide beam includes at least one narrow beam. The wide beam is interpreted as the first transmission beam and the narrow beams as the M transmission beams. See paragraph [0046]). In the same field of endeavor, Deenoo-916 teaches the first transmission beam is different from each of the M transmission beams (Deenoo-916 discloses a hierarchal beam structure where the control channels are carried on the wide beams, while the data channels are mapped to the narrow beams, thus, making the beam types different from each other. See paragraph [0164]). Therefore, it would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to modify the Xiang reference to incorporate distinctly identifying that the beams have different functions during the transmission process. The motivation to combine is for efficient resource allocation and simplified beam management. Regarding claim 4, Xiang further teaches wherein the first control information further comprises at least one of period duration or a period repetition quantity of the first resource. (Xiang discloses the control information includes an indication of a time-frequency resource subframe. It is known in the art that a subframe is a time unit which denotes a period duration. See paragraphs [0049] and [0051]). Regarding claim 9, Xiang further teaches wherein the resource location information comprises at least one of the following: a frame index, a slot index, a symbol index, a quantity of symbols, a sub channel index, a physical resource block (PRB) index, a resource element RE index, a symbol offset, or a slot offset. And wherein: the quantity of symbols is a quantity of symbols for sending the first reference signal in a slot; the slot offset is a quantity of offset slots between a slot in which the first reference signal is sent and a slot in which the first control information is sent; and the symbol offset is a quantity of offset symbols between a symbol for sending the first reference signal and a symbol for sending the first control information. (Xiang discloses the resource location information including a resource element index. See paragraph [0064]). Regarding claim 16, it is rejected for the same reasons outlined in claim 1.

Therefore, it would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to modify the Landström reference to incorporate determining the difference of the different beam gain information between the beams. The motivation to combine is to identify directivity and concentration for optimization. Claim 5 is rejected under 35 U.S.C. 103 as being unpatentable over Xiang in view of Deenoo-916 and further in view of Kang, Jiwon et al. (US 20210084640 A1, hereinafter referred to as Kang).
