Office Action

§102 §103
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 § 102 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)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. Claim(s) 1-4, 6, 7, 9, 14, 17, 18, and 20 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by MATSUMOTO US 20170048908. Regarding claims 1-4, 14, MATSUMOTO teaches a method of operating a transmitting radio node in a wireless communication network, the method comprising: transmitting first control signaling covering one or more first allocation units in a control transmission time interval (paragraph 7, "user terminal includes a controller configured to perform repetition of same control information using first and second control resources allocated continuously or discontinuously in a lime direction, in a control region having a predetermined time length and a predetermined frequency bandwidth"), and transmitting second control signaling covering one or more second allocation units in the control transmission time interval, the second control signaling being shifted relative to the first control signaling (paragraph 7, “user terminal includes a controller configured to perform repetition of same control information using first and second control resources allocated continuously or discontinuously in a time direction, in a control region having a predetermined time length and a predetermined frequency bandwidth"). Regarding claim 6, 17, the first control signaling and the second control signaling represent the one or both of a same information content and/or and payload (paragraph 7, repetition of same control information). Regarding claims 7, 18, the first control signaling comprises first reference signaling, and the second control signaling comprises second reference signaling, wherein the second control signaling is shifted relative to the first control signaling at least such that the second reference signaling is shifted relative to the first reference signaling. (paragraph 7, first and second control resources allocated continuously in a time direction). Regarding claims 9, 20, the first control signaling and the second control signaling are synchronised to each other (paragraph 7, first and second control resources allocated continuously in a time direction). (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. Claim(s) 1-5, 10, 16, 21 is/are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Cirik US 20220210818. Regarding claims 1-4, Cirik teaches a method of operating a transmitting radio node in a wireless communication network, the method comprising: transmitting first control signaling covering one or more first allocation units in a control transmission time interval (paragraph 7, "user terminal includes a controller configured to perform repetition of same control information using first and second control resources allocated continuously or discontinuously in a lime direction, in a control region having a predetermined time length and a predetermined frequency bandwidth"), and transmitting second control signaling covering one or more second allocation units in the control transmission time interval, the second control signaling being shifted relative to the first control signaling (For example, in FIG. 24 and FIG. 25, the plurality of downlink control signal/channel transmission/repetition occasions comprise a first downlink control signal/channel transmission/repetition occasion (e.g., PDCCH transmission/repetition occasion 1) and a second downlink control signal/channel transmission/repetition occasion (e.g., PDCCH transmission/repetition occasion 2), [0334]) Regarding claims 5, 16, one or both of the first control signaling and/or and the second control signaling is signaling on one or both of a physical control channel / PDCCH and/or and a physical broadcast channel. (PDCCH, [0334]). Regarding claims 10, 21, the second control signaling overlaps one or both in time and/or and frequency domain with the first control signaling (In the spatial/code domain repetition scheme, the plurality of downlink control signal/channel transmission occasions may overlap in frequency, [0348]). Claim Rejections - 35 USC § 103 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. Claim(s) 8, 19 is/are rejected under 35 U.S.C. 103 as being unpatentable over MATSUMOTO as applied to claims 1, 3 above, and further in view of Lee US 20200196052. MATSUMOTO is silent on one of both of the first control signaling and/or and the second control signaling are associated to first synchronisation signaling. Lee teaches control signaling for the purpose of synchronization ([0090]). Therefore it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention, to modify the system of MATSUMOTO by one of both of the first control signaling and/or and the second control signaling are associated to first synchronisation signaling, as suggested by Lee. This modification would benefit the system by synchronizing the mobile with the base station. Allowable Subject Matter Claims 11-13 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
