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.
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.
Claim(s) 2-4, 9-11 and 17-18 is/are rejected under 35 U.S.C. 103 as being unpatentable over Gan in view of Parkvall et al. (US 2017/0331577 A1, hereinafter “Parkvall”).
Regarding claims 2, and 9, Gan discloses that the position information is coordinates of a global position system (GPS) and that the network including the base station is a 5G network (see para. 0046 and 0062). Gan fails to disclose explicitly the base station adopts time division duplex (TDD) and includes a receiver configured to receive a positioning signal from a satellite positioning system, and the at least one processor configured to execute the instructions to acquire position information of the base station based on a positioning signal received via the receiver. However, Parkvall from a similar field of endeavor discloses the base station adopts time division duplex (TDD) and includes a receiver configured to receive a positioning signal from a satellite positioning system, and the at least one processor configured to execute the instructions to acquire position information of the base station based on a positioning signal received via the receiver (see para. 1166-1167 and 1707, TDD method). Thus, it would have been obvious to one ordinary skill in the art before the effective filing date of the claimed invention was made to include Parkvall TDD method and acquiring the coordinates of the global position system based on the positioning signal received from GPS of Gan. The method can be implemented in a receiver. The motivation of doing this is to improve spectral efficiency.
Regarding claims 3, 10, and 17, Gan discloses wherein the at least one
processor configured to execute the instructions to; transmit, to one or more
adjacent base stations by broadcast, state information of the base station together
with an identifier of the base station, and acquire, from the adjacent base station
by broadcast, state information of the adjacent base station together with an
identifier of the adjacent base station (see para. 0050, base station broadcasts configuration information including status information and cell ID to peripheral base stations).
Regarding claims 4, 11, and 18, Gan discloses all the subject matter but fails to mention wherein the state information sharing is performed by using a random backoff algorithm. However, Parkvall from a similar field of endeavor discloses wherein the state information sharing is performed by using a random backoff algorithm (see para. 1569, random backoff). Thus, it would have been obvious to include Parkvall random access backoff procedure into Gan access procedure. The method can be implemented in a message. The motivation of doing this is to prioritize data transmission.
Claim(s) 6 and 13 is/are rejected under 35 U.S.C. 103 as being unpatentable over Gan in view of Furuichi (US 2019/0274081)..
Regarding claims 6, and 13, Gan discloses all the subject matter but fails to mention explicitly further comprising a core, a radio unit (RU), a distributed unit (DU), and a central unit (CU), wherein the base station is a mobile base station operating according to a cellular communication standard. However, Furuichi from a similar field of endeavor discloses further comprising a core, a radio unit (RU), a distributed unit (DU), and a central unit (CU), wherein the base station is a mobile base station operating according to a cellular communication standard (see para. 0075). Thus, it would have been obvious to one ordinary skill in the before the effective filing date of the claimed invention was made to include Furuichi base unit components into Gan base station. The method can be implemented in a base station. The motivation of doing this is to separate processing function.
