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.
5. Claims 1 and 7 are rejected under 35 U.S.C. 103 as being unpatentable over

Allowable Subject Matter
9. Claims 16-20 contain allowable subject matter.
10. The following is a statement of reasons for the indication of allowable subject matter: Although the cited prior art teaches radio access technology along with spectrum translation, the prior art fail to teach a single limitation in combination with all the limitations of the claim.
Therefore, the prior art fail to teach generating an indication of a time shift based on the indication of the slot scheduling, the indication of the time shift corresponding to when a multi-radio access technology (RAT) translator is to expect to receive downlink communications from the communication network.
The dependent claims depend on independent claim 16, therefore, the dependent claims 17-20 contain allowable subject matter as well.
