DETAILED ACTION
Claims 18-34 have been cancelled. Claims 1-17 are pending and have been examined.
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
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 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)(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, 3-9, and 11-17 is/are rejected under 35 U.S.C. 102(a)(2) as being anticipated by US 20260254571 A1 to Muraoka et al. (hereinafter “Muraoka”).
As per claim 1, Muraoka discloses a method of operating a radio unit (RU) shared by multiple distributed units (DUs) of a radio access network (RAN) (Muraoka Fig. 1), the method comprising: transmitting, by one or more computing devices, a modified synchronization signal block (SSB) (Muraoka Fig. 1, 2, and [0063] FIG. 2 conceptually shows the SSB beam sweep performed by the TRPs 31 to 33 in a single cell (cell 51). To allow UEs 40 to select the best beam for initial access, each of the TRPs 31 to 33 uses a beam sweep 300. Specifically, each TRP transmits multiple SSBs, changing the beam direction each time it transmits an SSB. Each SSB contains a PSS, an SSS, a PBCH, and PBCH DMRS. In a case where multiple TRPs are arranged in a single cell, at least one of these TRPs may transmit only one SSB beam. In other words, at least one of the multiple TRPs in the cell may intermittently transmit one SSB beam in a predetermined direction at a predetermined cycle without performing a beam sweep.), wherein the modified SSB includes: a first SSB including time and frequency synchronization information for the multiple DUs for sharing the RU (Muraoka Fig. 1, 2, and [0063] FIG. 2 conceptually shows the SSB beam sweep performed by the TRPs 31 to 33 in a single cell (cell 51).

In other words, at least one of the multiple TRPs in the cell may intermittently transmit one SSB beam in a predetermined direction at a predetermined cycle without performing a beam sweep.); and at least a second SSB different from the first SSB, wherein the second SSB includes access information specific to a corresponding DU of the multiple DUs sharing the RU (Muraoka Fig. 1, 2, and [0063] FIG. 2 conceptually shows the SSB beam sweep performed by the TRPs 31 to 33 in a single cell (cell 51).
