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.
Claims 7 and 17 are rejected under 35 U.S.C. 103 as being unpatentable over Rico in view of Chang et al (US 2019/0174378) (hereinafter Chang).
Regarding claim 7, Rico does not expressly disclose the apparatus of claim 1, wherein: the one or more processors are configured to cause the apparatus to receive a common configuration indicating one or more first codeword-based RACH settings applying across a plurality of carriers; and to send the first signal, the one or more processors are configured to cause the apparatus to send the first signal in accordance with the common configuration.
Chang discloses the above recited limitations (see Chang, p. [0118], e.g., At step S220, the eNB sends the configuration information to a UE for the UE to perform random access, and p. [0120], e.g., The non-anchor carrier configuration information can be divided into non-anchor carrier common configuration information and non-anchor carrier dedicated configuration information. When a value of the indication information element is set to “true” or “setup” or “1”, the UE considers that a corresponding non-anchor carrier uses an uplink carrier and/or downlink carrier in the common configuration information, and p. [0128], e.g., the eNB configures common RACH-ConfigCommon-NB for an anchor carrier and all non-anchor carriers, and p. [0137], p. [0169]).
It would have been obvious to a person of ordinary skilled in the art before the effective filing date of the claimed invention to incorporate Chang’s teachings into Rico. The suggestion/motivation would have been to use the common configuration for defining general parameters of random access as suggested by Chang.
Regarding claim 17, the combined teaching of Rico and Chang disclose the apparatus of claim 11, wherein: the one or more processors are configured to cause the apparatus to send a common configuration indicating one or more first codeword-based RACH settings applying across a plurality of carriers; and to obtain the first signal, the one or more processors are configured to cause the apparatus to obtain the first signal in accordance with the common configuration (see Chang, p. [0118], e.g., At step S220, the eNB sends the configuration information to a UE for the UE to perform random access, and p. [0120], e.g., The non-anchor carrier configuration information can be divided into non-anchor carrier common configuration information and non-anchor carrier dedicated configuration information. When a value of the indication information element is set to “true” or “setup” or “1”, the UE considers that a corresponding non-anchor carrier uses an uplink carrier and/or downlink carrier in the common configuration information, and p. [0128], e.g., the eNB configures common RACH-ConfigCommon-NB for an anchor carrier and all non-anchor carriers, and p. [0137], p. [0169]).
