This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention.
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 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.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.

Regarding claim 1, Chen teaches a base station device (see Abstract base station/base station 1 and Fig. 1) comprising a plurality of wireless stations, the wireless stations each including:
a receiver that receives signals transmitted from a plurality of wireless terminal devices that transmit transmission data in a coordinated manner (see [0024] The plurality of mobile terminals 2 (i.e. wireless terminals) in the group share data to be transmitted to the base station 1. The data may be shared by communication between the mobile terminals 2 or by communication through the group head. The plurality of mobile terminals 2 in the group transmit, to the base station 1, the data to be transmitted to the base station 1 by Coordinated Multi-Point transmission (CoMP) between mobile terminals (cooperative transmission between terminals). More specifically, the plurality of mobile terminals 2 synchronously transmit, to the base station 1, the data to be transmitted to the base station 1 as a common message signal. The CoMP transmission is called "Joint Transmission".); and
a controller that selects a reference wireless station from among the wireless stations,
determines a phase of the transmission data for each of the wireless terminal devices at the selected reference wireless station (see [0041].. the base station 1 measures the phase of the channel based on the pilot signal and divides the plurality of mobile terminals 2 into one or more groups using the similarity of the phase of the channel to (02 of FIG. 2)….; further see [0073, 0095]), and
notifies the wireless terminal devices of the determined phase.
But fails to explicitly state about base stations having plurality of wireless stations as well as a controller that selects a reference wireless station from among the wireless stations, and notifies the wireless terminal devices of the determined phase.
However Samuel teaches col. 30- 35 and 44- 60 of col. 8 about BS1 to BS3 managed by master station/a server; further Samuel teaches in lines 30 -44 of col. 2 about Advantageously, the method comprises a step of election of at least one reference base station for the mobile terminal among the plurality of base stations according to at least one determined criterion belong to the group comprising: a temporal offset, a power of a signal received by at least on base station of said plurality, a connection quality between the at least one base station of said plurality and the mobile terminal, and an available bitrate of the at least one base station of said plurality; further see Fig. 5 #53. Further see Abstract about .. transmission of an item of information representative of a first temporal offset intended for the mobile terminal, the first offset being according to at least one reception time (740, 750, 760) of the first signal by at least one base station (BS1, BS2, BS3).

The taking into account of this criterion offers notably the advantage of electing the base station(s) receiving the signal with a power level in fact sufficient for the processing of the signal transmitted by the mobile terminal, quality of the link between at least one of the base stations 11 to 13 and the mobile terminal 10, the quality of the link between a base station and the mobile terminal is for example estimated by determining the Signal to Noise Ratio (SNR). Advantageously, the base station having the highest SNR is elected reference base station. According to a variant, the two base stations with the highest SNR are elected reference base stations. According to another variant, the base station(s) for which the SNR is greater than a threshold value (for example 10 dB or 20 dB) is (are) elected reference base station(s).
