Claims 1-7, & 9-20 are rejected under 35 U.S.C. 103 as being unpatentable over Wai et al (US20240333344) (hereinafter "Wai-1) in view of Wai et al (US20230327746) (hereinafter "Wai-2"), in further view of Xi et al (WO2018232090A1).
Regarding claim 1, Wai-1 teaches a control apparatus comprising:
one or more memories configured to store instructions ( Fig 1 104 [0124] capability of different memories); and
one or more processors configured to execute the instructions (Fig 1 200, [0123] processing device) to:
acquire a measurement result including information on reception qualities of a plurality of beams (Fig 9 903, 902, 903, [0066], [0074]-[0075] beam selection unit (apparatus) acquires information indicating the measurement result of reception quality of the beam specifying signal for each beam ID output);
update a database including information representing a relationship between the plurality of beams for each of a plurality of propagation environments, based on the measurement result (Fig 9, 111, 101, 300 [0113], [00122]-[0123], [0127]-[0135] storage of beam characteristics and optimal beam ID may include propagation environments based on measured results of acquired information of receptive quality, subsequently stores in a beam storage unit— updated when new beam information is stored—the data in table format having beam ID and beam associated with each other),
But Wai-1 fails to teach and perform selection processing for selecting a beam using the database.
However, Wai-2 teaches and perform selection processing for selecting a beam using the database (Fig 18, Fig 19, [0015], [0073]-[0076],[0086]-[0087], [0089]-[0091], performing discrete beam selection involving selection processing using transmission data, processing unit performing beam selection).
Wai-1 and Wai-2 are considered to be analogous to the claimed invention because both are in the same field of multiple beam selection, processing, and propagation environment categorization based on reception quality characteristics. Therefore, it would have been obvious to someone of ordinary skill in the art before the effective filing date of the claimed invention to have a motivation to combine the teaching of Wai-1 and Wai-2 to create and control apparatus and method for adaptive beam selection in 5G networks, where multiple beams are used to cover areas with high-frequency signals that suffer from propagation loss.
Wai-1 provides a general description of a communication control method and apparatus capable of performing beam selection with respect to an increase in the number of distributed antennas. Furthermore, Wai-2 provides a wireless communication method and apparatus that aims at improving communication between wireless stations by efficiently managing beam switching which involves beam control. Wai-2 aims to improve signal quality, reliability and efficiency in wireless networks, particularly in scenarios where multiple beams are used and need to be dynamically adjusted. Combining the teachings of Wai-1 and Wai-2 would allow for an control apparatus and method for adaptive beam selection in 5G networks, where multiple beams are used to cover areas with high-frequency signals that suffer from propagation loss. The motivation to combine both references is to improve beam selection accuracy, thereby enhancing communication reliability and efficiency in complex wireless environments.
But Wai-1 and Wai-2 fails to teach—
determine a first beam having highest reception quality for each of a plurality of propagation environments based on the measurement result;
the relationship represents a difference between a first reception quality of the first beam and a second reception quality of a second beam among the plurality of beams;
However, Xi teaches—
determine a first beam having highest reception quality for each of a plurality of propagation environments based on the measurement result ([0100]-[0101], explicitly says the WRTU measures RSRP per SS block (per-beam measurement) and selects the best N blocks (i.e. selects the beam(s) with the highest reception quality),;
the relationship represents a difference between a first reception quality of the first beam and a second reception quality of a second beam among the plurality of beams ([0149]-[0150] ,[0184], [0195]-[0197], report format uses “relative RSRP value” associated with each reported beam pair—explicit representation of a difference/relationship between a base (first) RSRP and other beams (i.e. relative/differential values), the “differential L1-RSRP reporting” phrase shows the spec contemplates reporting differences (deltas) rather than absolute values; the “relative RSRP value” pairs and use of offset values (SSB vs CSI-RS) show a concrete method of representing beam relationships as differences between the first (base) reception quality and other beams).
Wai-1, Wai-2 and Xi are considered to be analogous to the claimed invention because both are in the same field of multiple beam selection, processing, and propagation environment categorization based on reception quality characteristics. Therefore, it would have been obvious to someone of ordinary skill in the art before the effective filing date of the claimed invention to have a motivation to combine the combination teachings of Wai-1, Wai-2, and Xi to create and control apparatus and method for adaptive beam selection in 5G networks, where multiple beams are used to cover areas with high-frequency signals that suffer from propagation loss.

Regarding claim 3, Wai-1 fails to disclose wherein, in the information representing the relationship, the plurality of propagation environments are distinguished based on the first beam having the highest reception quality at a time point at which the measurement result is acquired, and
the one or more processors are configured to regard a beam currently in use or to be used next as the first beam, and select the relationship corresponding to the present propagation environment.
However, Wai-2 teaches wherein, in the information representing the relationship, the plurality of propagation environments are distinguished based on a first beam having a highest reception quality at a time point at which the measurement result is acquired ([0118], [0141]-[0143], [0239]-[0240] data processing unit determines which reception beam search signal has the best communication quality among the reception beam search signals transmitted, highest reception quality, beam ID read out (other characteristic data) reads out the beam ID from the received beam search signal determined by the data processing unit to have the best communication quality).
the one or more processors are configured to regard a beam currently in use or to be used next as the first beam, and select the relationship corresponding to the present propagation environment ([0030]-[0031], [0069]-[0070], [0086], beam search signal used in the discrete beam search selection—consider beam currently in use, selection of beam selection considered data involving propagation characteristics such as physical conditions).

Regarding claim 18, Wai-1 teaches wherein the one or more processors are configured to generate the database to be used in a first period of time and the database to be used in a second period of time (Fig 9, 111, 101, 300 [0113], [00122]-[0123], [0127]-[0135] generating data tables filled with beam type data, storage of beam characteristics and optimal beam ID may include propagation environments based on measured results of acquired information of receptive quality, subsequently stores in a beam storage unit— updated when new beam information is stored—the data in table format having beam ID and beam associated with each other).
Regarding claim 19, Wai-1 teaches a control method comprising:
acquiring a measurement result including information on reception qualities of a plurality of beams (Fig 9 903, 902, 903, [0066], [0074]-[0075] beam selection unit (apparatus) acquires information indicating the measurement result of reception quality of the beam specifying signal for each beam ID output);
updating a database including information representing a relationship between the plurality of beams for each of a plurality of propagation environments, based on the measurement result (Fig 9, 111, 101, 300 [0113], [00122]-[0123], [0127]-[0135] storage of beam characteristics and optimal beam ID may include propagation environments based on measured results of acquired information of receptive quality, subsequently stores in a beam storage unit— updated when new beam information is stored—the data in table format having beam ID and beam associated with each other),
But Wai-1 fails to teach and performing selection processing for selecting a beam using the database.
However, Wai-2 teaches and performing selection processing for selecting a beam using the database (Fig 18, Fig 19, [0015], [0073]-[0076],[0086]-[0087], [0089]-[0091], performing discrete beam selection involving selection processing using transmission data, processing unit performing beam selection).
Wai-1 and Wai-2 are considered to be analogous to the claimed invention because both are in the same field of multiple beam selection, processing, and propagation environment categorization based on reception quality characteristics. Therefore, it would have been obvious to someone of ordinary skill in the art before the effective filing date of the claimed invention to have a motivation to combine the teaching of Wai-1 and Wai-2 to create and control apparatus and method for adaptive beam selection in 5G networks, where multiple beams are used to cover areas with high-frequency signals that suffer from propagation loss.
Wai-1 provides a general description of a communication control method and apparatus capable of performing beam selection with respect to an increase in the number of distributed antennas. Furthermore, Wai-2 provides a wireless communication method and apparatus that aims at improving communication between wireless stations by efficiently managing beam switching which involves beam control. Wai-2 aims to improve signal quality, reliability and efficiency in wireless networks, particularly in scenarios where multiple beams are used and need to be dynamically adjusted. Combining the teachings of Wai-1 and Wai-2 would allow for an control apparatus and method for adaptive beam selection in 5G networks, where multiple beams are used to cover areas with high-frequency signals that suffer from propagation loss. The motivation to combine both references is to improve beam selection accuracy, thereby enhancing communication reliability and efficiency in complex wireless environments.
But Wai-1 and Wai-2 fails to teach—
determining a first beam having highest reception quality for each of a plurality of propagation environments based on the measurement result;
the relationship represents a difference between a first reception quality of the first beam and a second reception quality of a second beam among the plurality of beams;
However, Xi teaches—
determining a first beam having highest reception quality for each of a plurality of propagation environments based on the measurement result ([0100]-[0101], explicitly says the WRTU measures RSRP per SS block (per-beam measurement) and selects the best N blocks (i.e. selects the beam(s) with the highest reception quality),;
the relationship represents a difference between a first reception quality of the first beam and a second reception quality of a second beam among the plurality of beams ([0149]-[0150] ,[0184], [0195]-[0197], report format uses “relative RSRP value” associated with each reported beam pair—explicit representation of a difference/relationship between a base (first) RSRP and other beams (i.e. relative/differential values), the “differential L1-RSRP reporting” phrase shows the spec contemplates reporting differences (deltas) rather than absolute values; the “relative RSRP value” pairs and use of offset values (SSB vs CSI-RS) show a concrete method of representing beam relationships as differences between the first (base) reception quality and other beams).
