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 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. 1. Claims 2-4, 9-12 and 19 are rejected under 35 U.S.C. 103 as being unpatentable over Hakola (US 2020/0106168) in view of Rom (US 2024/0008031). 2. As per claim 2, Hakola teaches an apparatus for communication, comprising: an interface (Hakola, ¶0059 “interface); and a processing system that includes one or more processors and one or more memories coupled with the one or more processors (Hakola, ¶0059 “processor … memory …” . Furthermore, it’s well-known in the art to communicate the active antenna panel and/or when an active antenna panel switching will be performed so that to reduce overhead or improve communication performance - see Rom US 2024/0008031 for example ¶0007- 0010), the processing system configured to cause the apparatus to: obtain, via the interface, at least one transmit precoding matrix indicator indicative of at least one active group of a plurality of groups of antenna ports (Hakola, ¶0042 0044 “UE to provide a currently active antenna”), and output, via the interface, signals associated with at least one antenna port of the at least one active group (Hakola, ¶0045). Therefore, taking the combined teaching of Hakola and Rom as a whole, it would have been obvious to one having ordinary skill in the art at the time of the invention to implement the instant limitation for the benefit of reducing overhead or improving performance of the communication system. 3. Claims 10 & 11 are similarly analyzed as claim 2 for obviousness reasons discussed above. 4. As per claim 3, Hakola in view of Rom teaches the apparatus of claim 2, wherein the at least one transmit precoding matrix indicator is associated with a mapping of transmit precoding matrix indicators to active antenna groups (Hakola, ¶0033 0042 0044). 5. Claims 9 & 19 are similarly analyzed as claim 3 for obviousness reasons discussed above. 6. As per claim 4, Hakola in view of Rom teaches the apparatus of claim 2, wherein the at least one transmit precoding matrix indicator comprises at least one of: a first transmit precoding matrix indicator for a first active group of the at least one active group (Hakola, ¶0042 0044); or a second transmit precoding matrix indicator for a second active group of the at least one active group, wherein the second transmit precoding matrix indicator is different from the first transmit precoding matrix indicator and the second active group is different from the first active group (Hakola, ¶0042 0044). Allowable Subject Matter 7. Claims 5-8 and 13-18 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.
