The following is a quotation of 35 U.S.C. 112(d):
(d) REFERENCE IN DEPENDENT FORMS.—Subject to subsection (e), a claim in dependent form shall contain a reference to a claim previously set forth and then specify a further limitation of the subject matter claimed. A claim in dependent form shall be construed to incorporate by reference all the limitations of the claim to which it refers.
The following is a quotation of pre-AIA 35 U.S.C. 112, fourth paragraph:
Subject to the following paragraph [i.e., the fifth paragraph of pre-AIA 35 U.S.C. 112], a claim in dependent form shall contain a reference to a claim previously set forth and then specify a further limitation of the subject matter claimed. A claim in dependent form shall be construed to incorporate by reference all the limitations of the claim to which it refers.
Claims 1 and 8 rejected under 35 U.S.C. 112(d) or pre-AIA 35 U.S.C. 112, 4th paragraph, as being of improper dependent form for failing to further limit the subject matter of the claim upon which it depends, or for failing to include all the limitations of the claim upon which it depends. Claims 1 and 8 disclose “UE” abbreviation interpreted as user equipment. Applicant may cancel the claim(s), amend the claim(s) to place the claim(s) in proper dependent form, rewrite the claim(s) in independent form, or present a sufficient showing that the dependent claim(s) complies with the statutory requirements.
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.
The text of those sections of Title 35, U.S. Code not included in this action can be found in a prior Office action.
The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.

Every time the RU receives the latest reference signal from the BBU, the RU overwrites the existing local cache of the reference signal with the latest reference signal from the BBU… the RU uses, at block 706, the local copy of the reference signal obtained from the local memory at the RU and transmits it over the air. The RU continues to look for the reference signal sent from the BBU, and the RU transmits the local copy of the reference signal from the local memory at the RU to keep the UE connected to the network until the BBU and/or the fronthaul interface comes back to operation. This can also be done to minimize fronthaul traffic overhead for reference signal transmissions);

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 combination of Sung and Rajagopal by incorporating the teachings of Zhou because the method and device allow for transmission and reception of resources based on resource signals and resource management to maintain compatibility (Zhou, P. 281). The motivation is that by applying a well-known standard or protocol or machine to a system provides the system with significantly improved industrial applicability.
Regarding claim 10 Sung, Rajagopal, and Zhou teach the apparatus of claim 9, Rajagopal teaches…wherein the entries comprise: at least a first entry that represents at least a first block of PRBs for transmitting primary synchronization signals (PSSs) of the SSBs; at least a second entry that represents at least a second block of PRBs for transmitting physical broadcast channel (PBCH) signals of the SSBs; and at least a third entry that represents at least a third block of PRBs for transmitting secondary synchronization signals (SSSs) of the SSBs (P. 96).
Regarding claim 16 Sung and Rajagopal teach the method of claim 15, but do not teach…wherein: the reference signals comprise synchronization signal blocks (SSBs); and processing the reference signals comprises transmitting the SSBs on the fronthaul interface based on the modulation compression parameters.
Zhou teaches… wherein: the reference signals comprise synchronization signal blocks (SSBs); and processing the reference signals comprises transmitting the SSBs on the fronthaul interface based on the modulation compression parameters(Fig. 29, P. 272 discloses the naming of fronthaul link also described as a backhaul link where the SSB is transmitted based on the MCS and P.281 discloses…a control resource set group of the plurality of control resource set groups, based on a control resource set, of the control resource set group, on which the wireless device receives a DCI. [0281] In an example, the base station transmits RSs (e.g., SSBs/CSI-RSs) via a first TRP of the first cell. The wireless device may, based on one or more RSs of the RSs via the first TRP, perform beam management (e.g., comprising beam failure recovery), power control, CSI report, radio link monitoring, and/or radio resource management, for the first cell. ).

Regarding claim 17 Sung, Rajagopal, and Zhou teach the method of claim 16, Rajagopal teaches…wherein the entries comprise: at least a first entry that represents at least a first block of PRBs for transmitting primary synchronization signals (PSSs) of the SSBs; at least a second entry that represents at least a second block of PRBs for transmitting physical broadcast channel (PBCH) signals of the SSBs; and at least a third entry that represents at least a third block of PRBs for transmitting secondary synchronization signals (SSSs) of the SSBs (P.96 ).
Regarding claim 23 Sung and Rajagopal teach the method of claim 22, but do not teach…wherein the reference signals comprise synchronization signal blocks (SSBs).
Zhou teaches…. wherein the reference signals comprise synchronization signal blocks (SSBs) (Fig. 29, P. 272 discloses the naming of fronthaul link also described as a backhaul link where the SSB is transmitted based on the MCS and P.281 discloses…a control resource set group of the plurality of control resource set groups, based on a control resource set, of the control resource set group, on which the wireless device receives a DCI.
