5. The following is a quotation of 35 U.S.C. 103(a) which forms the basis for all obviousness rejections set forth in this Office action:
(a) A patent may not be obtained though the invention is not identically disclosed or described as set forth in section 102 of this title, if the differences between the subject matter sought to be patented and the prior art are such that the subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains. Patentability shall not be negatived by the manner in which the invention was made.
This application currently names joint inventors. In considering patentability of the claims under pre-AIA 35 U.S.C. 103(a), the examiner presumes that the subject matter of the various claims was commonly owned at the time any inventions covered therein were made absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and invention dates of each claim that was not commonly owned at the time a later invention was made in order for the examiner to consider the applicability of pre-AIA 35 U.S.C. 103(c) and potential pre-AIA 35 U.S.C. 102(e), (f) or (g) prior art under pre-AIA 35 U.S.C. 103(a).
The factual inquiries set forth in Graham v. John Deere Co., 383 U.S. 1, 148 USPQ 459 (1966), that are applied for establishing a background for determining obviousness under 35 U.S.C. 103(a) 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) 1, 4, 8, 11, 15, 18, 22 and 25 are rejected under 35 U.S.C. 103(a) as being unpatentable over R2-093723 (“Impact of CA on MAC layer”, 29 June – 03 July, 2009), in view of ETSI (“TS 136 331 V10.3.0”, November 2011), and Chun et al. (WO# 2010143851 A2)(with English translation and citations to U.S. Patent Application Publication # 2012/0076042 A1).
Regarding claim 1, the R2-093723 document teaches a method comprising:
receiving, by a wireless device (read as UE) from a base station (read as ENB), at least one radio resource control message (read as RRC signaling) comprising a plurality of configuration parameters for a plurality of random access channel resources (read as “… UE gets the system information including RACH configuration in non-camping component carrier by some way, such as RRC signaling similar to that in handover.”(Section 2.1, page 1));
However, the R2-093723 document fails to explicitly teach a radio resource control message comprising:
a preamble received target power parameter,
a threshold parameter,
measuring, by the wireless device, radio link quality of at least one radio link between the wireless device and the base station; and
transmitting, by the wireless device based on the preamble received target power parameter and via at least one random access channel resource, of the plurality of random access channel resources, that is selected based on the radio link quality, a preamble that is selected based on the threshold parameter.
The ETSI document teaches a radio resource control message (read as RRC messages (Section 6.2, page 108)) comprising:
a preamble received target power parameter (read as an initial preamble power (preambleInitialReceivedTargetPower) field (Section 6.2.1, page 180)),
a threshold parameter (read as Threshold for preamble selection (messagePowerOffsetGroupB)(Section 6.2.1, page 180)),
Therefore, it would have been obvious to a person of ordinary skill in the art at the time the invention was made to employ the function for generating and transmitting an RRC message comprising of IE RACH-configCommon as taught by the ETSI document with a UE that communicates with a base station and vice versa as taught by the R2-093723 document for the purpose of enhancing random access control information used by devices in a communication network.
However, the the R2-093723 document and the ETSI document fail to explicitly teach measuring, by the wireless device, radio link quality of at least one radio link between the wireless device and the base station; and
transmitting, by the wireless device based on the preamble received target power parameter and via at least one random access channel resource, of the plurality of random access channel resources, that is selected based on the radio link quality, a preamble that is selected based on the threshold parameter.

(read as “a step of selecting a physical random access channel (PRACH) resource on the uplink component carrier having the highest channel quality; and a step of transmitting a random access preamble to the base station using the selected PRACH resource.”(Fig(s).7 and 9-10, Abstract) Also, “The reference signal transmitted power may be provided to the user equipment by the higher layer.”(Paragraph [0109]) For example, “In selecting UL CC for a preamble retransmission, a user equipment calculates a preamble received target power (PREAMBLE_RECEIVED_TARGET_POWER) for all available UL CCs including PRACH resource and may be then able to compare it with a pathloss (PL) of DL CC. In particular, the user equipment calculates a formula of `x=PREAMBLE_RECEIVED_TARGET_POWER-PL` and may be then able to select a UL CC having a highest x as a UL CC for the preamble retransmission.”(Paragraph [0120]) Also, the function for receiving preamble received target power and other parameters and the function to send a preamble are taught in “3GPP standard documents (e.g., TS36.213, TS36.214, TS36.331, etc.).”(Paragraph [0109]))
Therefore, it would have been obvious to a person of ordinary skill in the art at the time the invention was made to employ the function for measuring and determining the highest channel quality and the function for selecting a PRACH and transmitting a preamble as taught by Chun et al. and the function for generating and transmitting an RRC message comprising of IE RACH-configCommon as taught by the ETSI document with a UE that communicates with a base station and vice versa as taught by the R2-093723 document for the purpose of improving connection selection based on random access parameters by devices in a communication network.

a power threshold,
receiving, by the base station from the wireless device, an indication of radio link quality of at least one radio link between the wireless device and the base station; and

The ETSI document teaches the function for generating and transmitting an RRC message comprising of IE RACH-configCommon. (Section(s) 6.2 and 6.2.1, pages 108 and 180)
Chun et al. teach “a method and apparatus for performing a random access in a wireless communication system that supports multi-carriers.”(Fig(s).7 and 9-10; Paragraph [0001])
However, the R2-093723 document, the ETSI document, and Chun et al. fail to explicitly teach transmitting, to the wireless device via a primary cell, a random access response.
Fwu et al. teach a method for transmitting, to the wireless device via a primary cell, a random access response. (read as Random Access Response (Paragraph [0064]); For example, “receiving 1020 a Random Access Response (RAR) at the UE from the eNodeB for the PCell.”(Paragraph [0064]))
Therefore, it would have been obvious to a person of ordinary skill in the art at the time the invention was made to employ the function for generating and exchanging a RAR for a PCELL as taught by Fwu et al., the function for measuring and determining the highest channel quality and the function for selecting a PRACH and transmitting a preamble as taught by Chun, and the function for generating and transmitting an RRC message comprising of IE RACH-configCommon as taught by the ETSI document by with a base station (ENB) that communicates with a UE and vice versa as taught by the R2-093723 document for the purpose of improving connection selection based on random access parameters by devices in a communication network.
Claims 5-7, 12-14, 19-21, and 26-28 are rejected under 35 U.S.C. 103(a) as being unpatentable over R2-093723 (“Impact of CA on MAC layer”, 29 June – 03 July, 2009), in view of ETSI (“TS 136 331 V10.3.0”, November 2011), Chun et al. (WO# 2010143851 A2)(with English translation and citations to U.S. Patent Application Publication # 2012/0076042 A1), and Yamada (U.S. Patent Application Publication # 2012/0257513 A1).
Regarding claims 5, 12, 19, and 26, and as applied to claims 1, 8, 15, and 22 above, the R2-093723 document teaches a random access procedure between a UE and ENB. (Section 2.1, pages 1-2)
The ETSI document teaches the function for generating and transmitting an RRC message comprising of IE RACH-configCommon. (Section(s) 6.2 and 6.2.1, pages 108 and 180)

However, the R2-093723 document, the ETSI document, and Chun et al. fail to explicitly teach wherein:
the plurality of configuration parameters for the plurality of random access channel resources are for a plurality of cells grouped into a plurality of cell groups;
the plurality of cell groups comprise a primary cell group and a secondary cell group; and
the secondary cell group comprises a plurality of secondary cells.
Yamada teaches a method wherein:
the plurality of configuration parameters for the plurality of random access channel resources are for a plurality of cells grouped into a plurality of cell groups (read as “The RRC signaling may indicate the PSCell based on one selected from the group consisting of an SCell with a random access channel (RACH), an SCell with a lowest order in a group configuration and an SCell that is a reference cell for uplink timing.”(Paragraph [0028]));
the plurality of cell groups comprise a primary cell group and a secondary cell group (read as “The RRC signaling may indicate the PSCell based on one selected from the group consisting of an SCell with a random access channel (RACH), an SCell with a lowest order in a group configuration and an SCell that is a reference cell for uplink timing.”(Paragraph [0028])); and
the secondary cell group comprises a plurality of secondary cells. (read as non-PCell group (Paragraph(s) [0050] and [0128]))
Therefore, it would have been obvious to a person of ordinary skill in the art at the time the invention was made to employ the function for generating and exchanging an RRC message with group indicators as taught by Yamada, the function for measuring and determining the highest channel quality and the function for selecting a PRACH and transmitting a preamble as taught by Chun et al., and the function for generating and transmitting an RRC message comprising of IE RACH-configCommon as taught by the ETSI document by with a base station (ENB) that communicates with a UE and vice versa as taught by the R2-093723 document for the purpose of improving connection selection based on random access parameters by devices in a communication network.

uplink transmission timing associated with the primary cell group is based on a first cell of the primary cell group; and
uplink transmission timing associated with the secondary cell group is based on a second cell of the secondary cell group.
Yamada teaches a method wherein:
uplink transmission timing associated with the primary cell group is based on a first cell of the primary cell group (uplink timing reference (Paragraph [0050]); For example, “Each group may have one specific cell that is used as an uplink timing reference.”(Paragraph [0050])); and
uplink transmission timing associated with the secondary cell group is based on a second cell of the secondary cell group. (uplink timing reference (Paragraph [0050]); For example, “Each group may have one specific cell that is used as an uplink timing reference.”(Paragraph [0050]))
Therefore, it would have been obvious to a person of ordinary skill in the art at the time the invention was made to employ the function for generating an uplink timing reference for a cell within group as taught by Yamada, the function for measuring and determining the highest channel quality and the function for selecting a PRACH and transmitting a preamble as taught by Chun et al., and the function for generating and transmitting an RRC message comprising of IE RACH-configCommon as taught by the ETSI document by with a base station (ENB) that communicates with a UE and vice versa as taught by the R2-093723 document for the purpose improving connection selection based on random access parameters by devices in a communication network.

transmitting, to the base station, an indication of radio link quality of the plurality of secondary cells;
receiving, from the base station, an indication of a random access channel resource, of the plurality of random access channel resources, associated with a secondary cell of the plurality of secondary cells; and
receiving, from the base station, a command to cause the transmitting the preamble.
Yamada et al. teach a method further comprising:
transmitting, to the base station, an indication of radio link quality of the plurality of secondary cells (read as Multi-Group Control Information (Fig.5 @ 531));
receiving, from the base station, an indication of a random access channel resource, of the plurality of random access channel resources, associated with a secondary cell of the plurality of secondary cells (read as Signal Information (Fig.5 @ 523)); and
receiving, from the base station, a command to cause the transmitting the preamble. (read as Time Advance Command(s) (Fig.5 @ 527))
Therefore, it would have been obvious to a person of ordinary skill in the art at the time the invention was made to employ the function for generating TA commands for a cell within group as taught by Yamada, the function for measuring and determining the highest channel quality and the function for selecting a PRACH and transmitting a preamble as taught by Chun, and the function for generating and transmitting an RRC message comprising of IE RACH-configCommon as taught by the ETSI document by with a base station (ENB) that communicates with a UE and vice versa as taught by the R2-093723 document for the purpose of improving connection selection based on random access parameters by devices in a communication network.

Response to Arguments
6. Applicant's arguments with respect to claim(s) 1-28 have been considered but are moot in view of the new ground(s) of rejection.
Conclusion
7. The prior art made of record and not relied upon is considered pertinent to Applicant’s disclosure:
ETSI (“TS 136 213 V10.3.0”, October 2011) document teach “From the physical layer perspective, the L1 random access procedure encompasses the transmission of random access preamble and random access response.” (Section 6.1, page 21) For example, the ETSI document teaches “A preamble index, a target preamble received power (PREAMBLE_RECEIVED_TARGET_POWER), a corresponding RA-RNTI and a PRACH resource are indicated by higher layers as part of the request.”(Section 6.1, page 21)
Yi et al. (U.S. Patent Application Publication # 2009/0316586 A1) teach “A RACH Preamble is selected. The Preamble Transmission counter value is compared with the Preamble Transmission maximum value. If the Preamble Transmission counter value equals the Preamble Transmission maximum value +1, the RRC entity is informed that the RACH procedure has problem. The selected RACH Preamble is transmitted.” (Paragraph [0068])
Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a).
A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
