DETAILED ACTION
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Response to Amendment
Amendments filed on 2/20/2026 (hereafter the amendments) are entered for prosecution. Claims 1-2, 4, 7-10, 12, and 14-20 remain pending in the application. The amendments change the scopes of the previously presented claims. New grounds of rejections are applied to the amended claims and the current Office Action is made FINAL as necessitated by the claim amendments.
The amendments have overcome each and every objection to the claims previously set forth in the Non-Final Office Action mailed 11/20/2025.
Response to Arguments
Applicant’s arguments with respect to claims 1-2, 4, 7-10, 12, and 14-20 have been considered but are not persuasive. Applicant argues that “the UL Gap of amended independent Claims 1 and 9 aims to intentionally suspend (stop) uplink transmission itself during a specific interval on a specific cell.” Remarks at 9 (emphasis added). However, as recited in claims 4 and 12, performing an uplink transmission during the UL gap is permitted through a cell other than the specific cell (“perform[ing], during the UL gap, an uplink transmission through the second cell”). Hugl discloses similar operations. A cell for PUCCH transmission is determined according to time domain / time-dependent pattern of Hugl, and an uplink transmission is performed through the determined cell (see Figs. 1-4 and corresponding description). Hence, all cell(s) of Hugl other than the determined cell suspend (stop) uplink transmission itself during a specific interval as determined by the time domain pattern just the same way as the specific cell would do according to claims 1 and 9. Applicant’s argument is not persuasive.
Claim Interpretation
The broadest reasonable interpretation (BRI) of “uplink (UL) gap” includes “interval(s)” or “duration(s)” in the time domain that is somehow related to uplink (UL), because, according to [0035] of PGPub of the instant application, “On the other hand, in the disclosure, the uplink cell that does not perform uplink transmission during the uplink gap times 212 and 214 may be referred to as a deactivated uplink cell. In addition, in the disclosure, the uplink cell that performs uplink transmission at times 211 and 213 other than the uplink gap time may be referred to as an activated uplink cell.” (Emphasis added.) See also time domain / time-dependent pattern in Fig.2. The BRI of UL gap, therefore, includes slot(s) or symbol(s) specified by the time domain pattern for a PUCCH cell because those slot(s) or symbol(s) are “interval(s)” or “duration(s)” in the time domain related to PUCCH.

Regarding claim 1, Hugl discloses:
A method (Fig.5) performed by a user equipment (UE) operating in carrier aggregation (CA) using a first cell and a second cell (Pcell, Scell, more than one serving cell) in a communication system (Abstract, One method may include configuring at least one user equipment (UE) with a configuration for more than one serving cell for physical uplink control channel (PUCCH) transmission within at least one physical uplink control channel (PUCCH) cell group; [0022] For URLLC services, low latency is important. Therefore, it had been proposed to enable PUCCH carrier switching for HARQ-ACK feedback which, e.g., for inter-band TDD with different UL/DL configurations can lead to some latency benefits. [0038] The example shown in FIG. 1 is provided based on the assumption that two cells are applicable for PUCCH transmission (Pcell & Scell); [0048] In some example embodiments, the network entity performing one or more of the procedures depicted in FIG. 5 may include or be included in a UE, SL UE, relay UE, mobile station, mobile device, stationary device, a wireless transmit/receive unit, IoT device or sensor, or the like.; See also [0049]), the method comprising:
receiving (510), from a base station (gNB), first information (Figs.1-4; time domain / time-dependent pattern) indicating an uplink (UL) gap configuration (slot(s) or symbol(s) where a cell is not the cell for PUCCH transmission per time domain / time-dependent pattern; slots# { 0,1,2}+k *pattern_length, k≥0 are UL gap(s) for Scell, when Pcell is the cell for PUCCH transmission at those slots. Similarly, slots# {3,4}+k *pattern_length, k≥0 are UL gap(s) for Pcell, when Scell is the cell for PUCCH transmission at those slots.) (Figs.1-4; [0027] Certain example embodiments described herein relate to the selection mechanism the UE would use to select a cell for PUCCH transmission in the case of PUCCH cell switching based on semi-static configuration (i.e., Alternative 2). One example embodiment may relate to the semi-static configuration of a cell carrying the PUCCH at certain times (i.e., time domain pattern of cell for PUCCH). [0038] ... The example shown in FIG. 1 is provided based on the assumption that two cells are applicable for PUCCH transmission (Pcell & Scell)—Pcell is associated with ‘0’ and SCell is associated with a value of ‘1’ in the configured time-domain pattern, that the configured reference SCS as well as the SCS of two cells is 15 kHz SCS (i.e. slot length of 1 ms), and that the time-domain configuration granularity is on slot level and the periodicity of the pattern is 5 ms (i.e., pattern length of 5 slots). For the example, the gNB configured the pattern ‘00011’ for the 5 ms periodicity with slot granularity (i.e. lms granularity for the 15 kHz SCS). [0039] Based on the configured time-domain pattern for the PUCCH cell of ‘00011’, the UE may determine the PUCCH cell given by the pattern. Namely, for slots# { 0,1,2}+k *pattern_length, k≥0, the UE may determine the Pcell to be the cell for PUCCH transmission. This is shown as shaded grey for slots 0 to 2 and 5 to 7 in the example of FIG. 1. Based on the pattern with the ‘1’s, the Scell may be configured as the cell for PUCCH transmission, which means that for slots# {3,4}+k*pattern_length, k≥0, the SCell is selected. [0049] As illustrated in the example of FIG. 5, at 505, the method may include receiving, from a gNB, configuration information with more than one serving cell for PUCCH transmission within at least one PUCCH cell group. In addition, the method may include, at 510, receiving, from the gNB, configuration information with a time-dependent pattern of the applicable PUCCH cell.; See also [0034] and Figs.1-4);
identifying (515), based on the first information (Figs.1-4; time domain / time-dependent pattern), a periodicity (periodicity of the time-domain pattern) and a length (lengths of slots or symbols where a cell is not the cell for PUCCH transmission per time domain / time-dependent pattern) of a UL gap (slot(s) or symbol(s) where a cell is not the cell for PUCCH transmission per time domain / time-dependent pattern; slots# { 0,1,2}+k *pattern_length, k≥0 are UL gap(s) for Scell, when Pcell is the cell for PUCCH transmission at those slots. Similarly, slots# {3,4}+k *pattern_length, k≥0 are UL gap(s) for Pcell, when Scell is the cell for PUCCH transmission at those slots.) associated with the first cell ([0038] FIG. 1 illustrates an example of the baseline operation of the cell selection for PUCCH based on semi-static configuration, according to an embodiment. The example shown in FIG. 1 is provided based on the assumption that two cells are applicable for PUCCH transmission (Pcell & Scell)—Pcell is associated with ‘0’ (hence when the pattern indicates ‘0’, Pcell (not Scell) is the cell for PUCCH transmission) and SCell is associated with a value of ‘1’ (hence when the pattern indicates ‘1’, Scell (not Pcell) is the cell for PUCCH transmission) in the configured time-domain pattern,… For the example, the gNB configured the pattern ‘00011’ for the 5 ms periodicity with slot granularity (i.e. 1ms granularity for the 15 kHz SCS). [0039] Based on the pattern with the ‘1’s, the Scell may be configured as the cell for PUCCH transmission; [0049] In an embodiment, the method may include, at 515, determining the cell for PUCCH transmission of a required UCI transmission based on the configured time-dependent pattern.; See also Figs.2-4 and descriptions thereof.); and
performing (530) an uplink transmission (UCI transmission) through the first cell (the determined cell for PUCCH transmission; Pcell during slots# { 0,1,2}+k *pattern_length, k≥0 (i.e., during UL gap(s) for Scell); Scell during slots# {3,4}+k *pattern_length, k≥0 (i.e., during UL gap(s) for Pcell)) in case that the uplink transmission (UCI transmission) does not overlap with the UL gap (slot(s) or symbol(s) where a cell is not the cell for PUCCH transmission per time domain / time-dependent pattern; slots# { 0,1,2}+k *pattern_length, k≥0 are UL gap(s) for Scell, when Pcell is the cell for PUCCH transmission at those slots. Similarly, slots# {3,4}+k *pattern_length, k≥0 are UL gap(s) for Pcell, when Scell is the cell for PUCCH transmission at those slots.) ([0050] As further illustrated in the example of FIG. 5, the method may include, at 520, performing UCI multiplexing and PUCCH resource determination according to the configuration used on the determined cell for PUCCH transmission. The method may also include, at 525, determining the validity of PUCCH resource on the determined cell for PUCCH transmission. In an embodiment, the method may include, at 530, UCI transmission on PUCCH on the determined cell for PUCCH transmission or on PUSCH.; A cell transmits PUCCH when the cell for PUCCH transmission according to the pattern. In other words, the cell’s PUCCH transmission does not overlap with “slot(s) or symbol(s) where the cell is not the cell for PUCCH transmission per time domain / time-dependent pattern”.).
Hugl further disclose the first information is received as RRC configuration ([0028] Certain embodiments may be based on gNB configuration (such as RRC) determining the PUCCH cell given a semi-statically configured timing relation (i.e., time pattern) of the cell carrying PUCCH. An embodiment provides for operation for the time-dependent configuration of a cell which is to carry the PUCCH and the related PUCCH resource selection. Example embodiments consider different options on the RRC configuration of the time-dependent PUCCH cell as well as the operation for cells having different subcarrier spacings (SCS).; See also [0034], [0036], [0054], [0055]).
Hugl does not disclose transmitting, to the base station, second information indicating that the RRC configuration is received.
However, Zhang discloses:
transmitting, to a base station (network device), second information (an acknowledgment message for confirming the configuration information) indicating that RRC configuration (configuration information carried by RRC signaling) is received (Fig.4; pp.10-11, Step 401: The terminal device receives the high layer signaling sent by the network device, where the high layer signaling includes at least configuration information related to the terminal device receiving or transmitting the physical layer signal; Step 402: The terminal device sends, to the network device, an acknowledgment message for confirming the configuration information, where the acknowledgment message is carried by MAC signaling or physical layer signaling. In step 401, the terminal device receives configuration information sent by the network device for the terminal device to send or receive a signal related to a physical layer. The configuration information is carried by the high layer signaling, and the high layer signaling may be RRC signaling or MAC signaling.).
It would have been obvious before the effective filing date of the claimed invention to a person of ordinary skill in the art to modify the method of Hugl to comprise transmitting, to the base station, second information indicating that the RRC configuration is received as taught by Zhang, so that the transmission reliability of the transmission configuration itself is improved and/or the configuration effective blur period during configuration is reduced. (Zhang, p.11, According to the foregoing embodiment, after receiving the configuration information related to receiving or transmitting the physical layer signal, the terminal device receives or sends at least MAC signaling or physical layer signaling for confirming the configuration information. . Thereby, the transmission reliability of the transmission configuration itself is improved and/or the configuration effective blur period during configuration is reduced.).
Regarding claims 2, 8, 10, and 15, Hugl discloses:
wherein the first information (Figs.1-4; time domain / time-dependent pattern) is received (transmitted) based on a radio resource control message (RRC) (radio resource configuration (RRC))(See [0028], [0034], [0036], [0054], [0055]) and includes information indicating the periodicity (periodicity of the time-domain pattern) of the UL gap (slot(s) or symbol(s) where a cell is not the cell for PUCCH transmission per time domain / time-dependent pattern; slots# { 0,1,2}+k *pattern_length, k≥0 are UL gap(s) for Scell, when Pcell is the cell for PUCCH transmission at those slots. Similarly, slots# {3,4}+k *pattern_length, k≥0 are UL gap(s) for Pcell, when Scell is the cell for PUCCH transmission at those slots.) and information indicating the length (lengths of slots or symbols where a cell is not the cell for PUCCH transmission per time domain / time-dependent pattern) of the UL gap (slot(s) or symbol(s) where a cell is not the cell for PUCCH transmission per time domain / time-dependent pattern; slots# { 0,1,2}+k *pattern_length, k≥0 are UL gap(s) for Scell, when Pcell is the cell for PUCCH transmission at those slots. Similarly, slots# {3,4}+k *pattern_length, k≥0 are UL gap(s) for Pcell, when Scell is the cell for PUCCH transmission at those slots.) ([0034] According to certain embodiments, the gNB may further configure the UE with a time-dependent pattern of the applicable PUCCH cell. The granularity of the time-domain pattern may be defined in the specification (fixed) or may be configurable to the UE. The granularity of the time-domain pattern may be in multiple of slots (N slots) or symbols (M symbols). In one example, the granularity may be 2 symbols, 7 symbols (for normal CP, 6 symbols for extended CP) or a slot to align with the Release-16 PUCCH configuration of allowing slot or sub-slot based PUCCH configuration. The periodicity of the time-domain pattern may be pre-determined in the specification or may be based on RRC configuration. In one example implementation, the configurable periodicity may have the same candidate values as the TDD UL/DL configuration (e.g., 0.5, 0.625, 1, 1.25, 2, 2.5, 3, 4, 5 and 10 ms). [0039] Based on the configured time-domain pattern for the PUCCH cell of ‘00011’, the UE may determine the PUCCH cell given by the pattern. Namely, for slots# { 0,1,2}+k *pattern_length, k≥0, the UE may determine the Pcell to be the cell for PUCCH transmission. This is shown as shaded grey for slots 0 to 2 and 5 to 7 in the example of FIG. 1. Based on the pattern with the ‘1’s, the Scell may be configured as the cell for PUCCH transmission, which means that for slots# {3,4}+k*pattern_length, k≥0, the SCell is selected. [0054] In some embodiments, a periodicity of the time-domain pattern may be fixed in the specification or determined based on radio resource configuration (RRC). According to one embodiment, the configuration of the time-domain pattern may include a reference subcarrier spacing (SCS) to determine a timing and granularity of the time-domain pattern).
Regarding claim 4, Hugl discloses:
performing (530), during the UL gap (slot(s) or symbol(s) where a cell is not the cell for PUCCH transmission per time domain / time-dependent pattern; slots# { 0,1,2}+k *pattern_length, k≥0 are UL gap(s) for Scell, when Pcell is the cell for PUCCH transmission at those slots. Similarly, slots# {3,4}+k *pattern_length, k≥0 are UL gap(s) for Pcell, when Scell is the cell for PUCCH transmission at those slots.), an uplink transmission (UCI transmission) through the second cell (the determined cell for PUCCH transmission; Pcell during slots# { 0,1,2}+k *pattern_length, k≥0 (i.e., during UL gap(s) for Scell); Scell during slots# {3,4}+k *pattern_length, k≥0 (i.e., during UL gap(s) for Pcell)) or a downlink reception through first cell.
Regarding claim 7, Hugl discloses:

Therefore, it had been proposed to enable PUCCH carrier switching for HARQ-ACK feedback which, e.g., for inter-band TDD with different UL/DL configurations can lead to some latency benefits. [0038] The example shown in FIG. 1 is provided based on the assumption that two cells are applicable for PUCCH transmission (Pcell & Scell); See also [0049]), first information (Figs.1-4; time domain / time-dependent pattern) indicating an uplink (UL) gap configuration (slot(s) or symbol(s) where a cell is not the cell for PUCCH transmission per time domain / time-dependent pattern; slots# { 0,1,2}+k *pattern_length, k≥0 are UL gap(s) for Scell, when Pcell is the cell for PUCCH transmission at those slots. Similarly, slots# {3,4}+k *pattern_length, k≥0 are UL gap(s) for Pcell, when Scell is the cell for PUCCH transmission at those slots.) (Figs.1-4; [0027] Certain example embodiments described herein relate to the selection mechanism the UE would use to select a cell for PUCCH transmission in the case of PUCCH cell switching based on semi-static configuration (i.e., Alternative 2). One example embodiment may relate to the semi-static configuration of a cell carrying the PUCCH at certain times (i.e., time domain pattern of cell for PUCCH). [0038] ...

For the example, the gNB configured the pattern ‘00011’ for the 5 ms periodicity with slot granularity (i.e. lms granularity for the 15 kHz SCS). [0039] Based on the configured time-domain pattern for the PUCCH cell of ‘00011’, the UE may determine the PUCCH cell given by the pattern. Namely, for slots# { 0,1,2}+k *pattern_length, k≥0, the UE may determine the Pcell to be the cell for PUCCH transmission. This is shown as shaded grey for slots 0 to 2 and 5 to 7 in the example of FIG. 1. Based on the pattern with the ‘1’s, the Scell may be configured as the cell for PUCCH transmission, which means that for slots# {3,4}+k*pattern_length, k≥0, the SCell is selected. [0052] As illustrated in the example of FIG. 6, the method may include, at 605, configuring at least one UE with a configuration for more than one serving cell for PUCCH transmission within at least one PUCCH cell group. The method may also include, at 610, configuring the at least one UE with a configuration for a time-domain pattern or time-dependent pattern of an applicable PUCCH cell within the at least one PUCCH cell group.; See also [0034] and Figs.1-5); and

Similarly, slots# {3,4}+k *pattern_length, k≥0 are UL gap(s) for Pcell, when Scell is the cell for PUCCH transmission at those slots.) associated with the first cell is identified ([0038] FIG. 1 illustrates an example of the baseline operation of the cell selection for PUCCH based on semi-static configuration, according to an embodiment. The example shown in FIG. 1 is provided based on the assumption that two cells are applicable for PUCCH transmission (Pcell & Scell)—Pcell is associated with ‘0’ (hence when the pattern indicates ‘0’, Pcell (not Scell) is the cell for PUCCH transmission) and SCell is associated with a value of ‘1’ (hence when the pattern indicates ‘1’, Scell (not Pcell) is the cell for PUCCH transmission) in the configured time-domain pattern,… For the example, the gNB configured the pattern ‘00011’ for the 5 ms periodicity with slot granularity (i.e. 1ms granularity for the 15 kHz SCS).

Example embodiments consider different options on the RRC configuration of the time-dependent PUCCH cell as well as the operation for cells having different subcarrier spacings (SCS).; See also [0034], [0036], [0054], [0055]).

Regarding claim 9, Hugl discloses:
A user equipment (UE) (Fig.7B, 20) operating in carrier aggregation (CA) using a first cell and a second cell (Pcell, Scell, more than one serving cell) in a communication system (Abstract, One method may include configuring at least one user equipment (UE) with a configuration for more than one serving cell for physical uplink control channel (PUCCH) transmission within at least one physical uplink control channel (PUCCH) cell group; [0022] For URLLC services, low latency is important. Therefore, it had been proposed to enable PUCCH carrier switching for HARQ-ACK feedback which, e.g., for inter-band TDD with different UL/DL configurations can lead to some latency benefits.

In step 401, the terminal device receives configuration information sent by the network device for the terminal device to send or receive a signal related to a physical layer. The configuration information is carried by the high layer signaling, and the high layer signaling may be RRC signaling or MAC signaling.).

(Zhang, p.11, According to the foregoing embodiment, after receiving the configuration information related to receiving or transmitting the physical layer signal, the terminal device receives or sends at least MAC signaling or physical layer signaling for confirming the configuration information. . Thereby, the transmission reliability of the transmission configuration itself is improved and/or the configuration effective blur period during configuration is reduced.).

In an embodiment, apparatus 10 may be a node, host, or server in a communications network or serving such a network. For example, apparatus 10 may be a network node, a sensing node, satellite, base station, a Node B, an evolved Node B (eNB), 5G Node B or access point, next generation Node B (NG-NB or gNB), TRP, HAPS, integrated access and backhaul (IAB) node, and/or a WLAN access point, associated with a radio access network, such as a LTE network, 5G or NR. In some example embodiments, apparatus 10 may be an eNB in LTE or gNB in 5G.), comprising:
a transceiver (Fig.7A, 18); and
a controller (Fig.7A, 12, 14) coupled with the transceiver (Fig.7A, 18) and configured to:
transmitting (610), to a user equipment (UE) operating in carrier aggregation (CA) using a first cell and a second cell (Pcell, Scell, more than one serving cell) (Abstract, One method may include configuring at least one user equipment (UE) with a configuration for more than one serving cell for physical uplink control channel (PUCCH) transmission within at least one physical uplink control channel (PUCCH) cell group; [0022] For URLLC services, low latency is important. Therefore, it had been proposed to enable PUCCH carrier switching for HARQ-ACK feedback which, e.g., for inter-band TDD with different UL/DL configurations can lead to some latency benefits. [0038] The example shown in FIG. 1 is provided based on the assumption that two cells are applicable for PUCCH transmission (Pcell & Scell); See also [0049]), first information (Figs.1-4; time domain / time-dependent pattern) indicating an uplink (UL) gap configuration (slot(s) or symbol(s) where a cell is not the cell for PUCCH transmission per time domain / time-dependent pattern; slots# { 0,1,2}+k *pattern_length, k≥0 are UL gap(s) for Scell, when Pcell is the cell for PUCCH transmission at those slots. Similarly, slots# {3,4}+k *pattern_length, k≥0 are UL gap(s) for Pcell, when Scell is the cell for PUCCH transmission at those slots.) (Figs.1-4; [0027] Certain example embodiments described herein relate to the selection mechanism the UE would use to select a cell for PUCCH transmission in the case of PUCCH cell switching based on semi-static configuration (i.e., Alternative 2).

For the example, the gNB configured the pattern ‘00011’ for the 5 ms periodicity with slot granularity (i.e. lms granularity for the 15 kHz SCS). [0039] Based on the configured time-domain pattern for the PUCCH cell of ‘00011’, the UE may determine the PUCCH cell given by the pattern. Namely, for slots# { 0,1,2}+k *pattern_length, k≥0, the UE may determine the Pcell to be the cell for PUCCH transmission. This is shown as shaded grey for slots 0 to 2 and 5 to 7 in the example of FIG. 1. Based on the pattern with the ‘1’s, the Scell may be configured as the cell for PUCCH transmission, which means that for slots# {3,4}+k*pattern_length, k≥0, the SCell is selected.

In step 401, the terminal device receives configuration information sent by the network device for the terminal device to send or receive a signal related to a physical layer. The configuration information is carried by the high layer signaling, and the high layer signaling may be RRC signaling or MAC signaling.).
It would have been obvious before the effective filing date of the claimed invention to a person of ordinary skill in the art to modify the method of Hugl to comprise receiving, from the user equipment, second information indicating that the RRC configuration is received as taught by Zhang, so that the transmission reliability of the transmission configuration itself is improved and/or the configuration effective blur period during configuration is reduced.
