Claim Rejections - 35 USC § 112
The following is a quotation of 35 U.S.C. 112(b):
(b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention.
The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph:
The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention.
Claim(s) 8 rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor, or for pre-AIA the applicant regards as the invention.
Claim 8 recites the limitation "wherein the first signal comprises a first SSB", which renders the claim indefinite. It is unclear whether the “a first SSB” in claim 8 refers to the same SSB as the “a first SSB” recited in claim 2 or a different SSB due to the lack of a proper antecedent basis.
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.
Claim(s) 1-3, 6-11, 13-17, and 20 rejected under 35 U.S.C. 103 as being unpatentable over Li et al. (U.S. Patent Application Publication No. 20190132882, hereafter “Li”) in view of Ly et al. (U.S. Patent Application Publication No. 20230362847, hereafter “Ly”).
Examiner’s note: in what follows, references are drawn to Li unless otherwise mentioned.
With respect to independent claims:
Regarding claim 1, A transmission processing method, comprising:
determining, by a terminal, a first Physical Random Access Channel (PRACH) transmission occasion, wherein the first PRACH transmission occasion corresponds to analog beams of (para [0156]: a UE first detects the SS/PBCH block(s) from the gNB and selects a suitable SS/PBCH block for the RACH procedure (interpreted as “corresponds to analog beams of a wireless auxiliary device”, the gNB is interpreted as “a wireless auxiliary device”). Then UE obtains the configuration of a control resource set (CORESET) for receiving PDCCH, which schedules the system information blocks that contain the PRACH configuration. From the PRACH configuration, the UE obtains one or multiple of the following RA related parameters, such as a PRACH preamble format, indicator to use the 2-step RA or the 4-step RA, a configuration of Msg1 occasion burst, a configuration of slot structure for Msg1 transmission, an indicator to support wideband LBT down-selection for PRACH, and the like. From the Msg1 configuration, the mapping rule between the selected SS block and Msg1 occasions, the UE obtains the time and frequency resources to transmit Msg1.) (para [0310]: the UE can determine its available PRACH occasions within an association period of SS/PBCH blocks to the PRACH occasions (interpreted as “determining, by a terminal, a first Physical Random Access Channel (PRACH) transmission occasion … corresponds to analog beams of a wireless auxiliary device”), which can be one or multiple PRACH configuration periods.)(The missing/crossed out limitation ‘ will be discussed in view of Ly.); and
sending, by the terminal, a first message Msg1 on the first PRACH transmission occasion (para [0100]: The UE 104 may select a PRACH preamble according to the SSB that indicates the type of SSB received by the UE 104. The PRACH transmitted to the base station 102 by the UE 104 may comprise the selected PRACH preamble (interpreted as “a first message Msg1”).).
Li does not specifically teach about the “a wireless auxiliary device” as recited in claim 1.
It, however, had been known in the art before the effective date of the instant application as shown by Ly. In para [0086] of Ly, Ly discloses that: The UE 104 b (interpreted as “a terminal”) may receive a type 1 SSB from base station 102 after the type 1 SSB transmission has been reflected by the RIS 410 (interpreted as “analog beams of a wireless auxiliary device”) (The RIS is ‘Reconfigurable Intelligent Surface’ and is interpreted as “a wireless auxiliary device”, see para [0052] of the Specification of the Instant Application).
Therefore, it would have been obvious to one of ordinary skill in the art at the time of instant application to modify Li's method by using the teaching of Ly to receive the SS/PBCH block(s) from the gNB after the SSB transmission has been reflected by the Reconfigurable Intelligent Surface (“RIS”). In 5G NR technology, the wireless communication may involve the transmission and propagation of signals using reconfigurable intelligent surfaces (RIS) (see para [0003] of Ly).
Regarding claim 15, it is a terminal claim corresponding to the method claim 1, except limitations “a processor (Fig. 3 and para [0103]: a processor 340); and a memory having a computer program or an instruction stored thereon (Fig. 3 and para [0103]: a memory 360. The memory 360 includes an operating system (OS) 361 and one or more applications 362.)” and is therefore rejected for the similar reasons set forth in the rejection of claim 1.
Regarding claim 20, it is a non-transitory computer readable storage medium claim corresponding to the method claim 1, except limitations “A non-transitory computer readable storage medium (para [0021]: Moreover, various functions described below can be implemented or supported by one or more computer programs, each of which is formed from computer readable program code and embodied in a computer readable medium… A “non-transitory” computer readable medium excludes wired, wireless, optical, or other communication links that transport transitory electrical or other signals. A non-transitory computer readable medium includes media where data can be permanently stored and media where data can be stored and later overwritten, such as a rewritable optical disc or an erasable memory device.” and is therefore rejected for the similar reasons set forth in the rejection of claim 1.

From the PRACH configuration, the UE obtains one or multiple of the following RA related parameters (interpreted as “the first transmission parameter is a relevant parameter of a Synchronization Signal and PBCH Block (SSB) and the wireless auxiliary device”), such as a PRACH preamble format, indicator to use the 2-step RA or the 4-step RA, a configuration of Msg1 occasion burst, a configuration of slot structure for Msg1 transmission, an indicator to support wideband LBT down-selection for PRACH, and the like.

Otherwise, the UE can segment a bandwidth for LBT, for example into two contiguous segments, and measure an energy level over each bandwidth segment 2302. When the energy level over any segment is below (Γ−3) dB, the UE can transmit PRACH over the segment and the LBT process is completed (interpreted as “determining, by the terminal, whether to send the Msg1 on the first PRACH transmission occasion corresponding to the first SSB”).
