[0040] Figure 1 is a schematic diagram of a wireless communication system 10 according to one embodiment of the present disclosure. The wireless communication system 10 is, in short, composed of a controller 12, a network 14, and a plurality of communication devices 16. The wireless communication system 10 may be any wireless communication system such as a wireless local area network (WLAN) system (e.g., Wi-Fi®), a personal area network (PAN) system (e.g., Bluetooth® (BT)), a digital video broadcasting (DVB) system, a long-term evolution (LTE) system, a long-term evolution advanced (LTE-A) system, or a fifth-generation (5G) system, but is not limited to such systems in this specification.

[0041] The wireless communication system 10 can support time-division duplex (TDD) mode, frequency-division duplex (FDD) mode, TDD-FDD joint operation mode, non-terrestrial network (NTN) mode, or license-assisted access (LAA) mode. That is, the controller 12, network 14, and communication device 16 can communicate via an FDD carrier, TDD carrier, license carrier (licensed serving cell), and / or an unlicensed carrier (unlicensed serving cell). Furthermore, the wireless communication system 10 can support carrier aggregation (CA). That is, the controller 12, network 14, and communication device 16 can communicate via multiple serving carriers (e.g., multiple channels (CH)), including a primary carrier (e.g., primary CH) and one or more secondary carriers (e.g., secondary CH).

[0042] In Figure 1, the controller 12, network 14, and communication device 16 are used simply to illustrate the structure of the wireless communication system 10. In reality, the controller 12 is a dedicated network device or application that functions as a central command center for managing and optimizing the wireless communication system 10. The controller 12 is designed to handle the network 14 and simplify the management of the wireless communication system 10, ensuring consistent performance, security, and reliability throughout the wireless communication system 10. By managing and monitoring the network 14, the controller 12 enables network administrators to deploy, configure, and maintain the wireless communication system 10.

[0043] In one embodiment, network 14 may be a WLAN including at least one access point (AP) and / or at least one hotspot. In one embodiment, network 14 may be a universal terrestrial radio access network (UTRAN) including at least one node B (NB) in a universal mobile communications system (UMTS). In one embodiment, network 14 may be an evolved UTRAN (E-UTRAN) including at least one evolved NB (eNB) and / or at least one relay node in a long-term evolution (LTE) system, an LTE-A system, or an evolved version of the LTE-A system. In one embodiment, network 14 may be a next-generation radio access network (NG-RAN) including at least one next-generation node B (gNB) and / or at least one fifth-generation (5G) base station (BS). In one embodiment, the gNB or 5G BS of network 14 may include an NTN gateway and an NTN payload. In one embodiment, the gNB or 5G BS of network 14 may be a transmit / receive point (TRP). In one embodiment, the network 14 may be any BS that conforms to a specific communication standard in order to communicate with the controller 12 and / or the communication device 16.

[0044] The communication device 16 may be a station (STA) (e.g., a non-AP STA), user equipment (UE), a very small earth station (VSAT), low-cost equipment (e.g., machine-type communication (MTC) equipment), device-to-device (D2D) communication equipment, narrowband Internet of Things (IoT) (NB-IoT), mobile phones, laptops, tablet computers, e-books, portable computer systems, home appliances, vehicles, ships, airplanes, or a combination thereof. Furthermore, the network 14 and the communication device 16 can be viewed as a transmitter or receiver based on direction (i.e., transmission direction). For example, in the case of an uplink (UL), the communication device 16 is the transmitter and the network 14 is the receiver; in the case of a downlink (DL), the network 14 is the transmitter and the communication device 16 is the receiver. Note that an STA with AP functionality enabled can operate as an AP.

[0045] Figure 2 is a schematic diagram of a communication device 20 according to one embodiment of the present disclosure. The communication device 20 may be the controller 12, network 14, or communication device 16 in Figure 1, but is not limited herein. The communication device 20 may include at least one processing circuit 200, such as a microprocessor or application-specific integrated circuit (ASIC), at least one storage device 210, and at least one communication interface device 220. The at least one storage device 210 may be any data storage device capable of storing program code 214 accessed and executed by the at least one processing circuit 200. Examples of the at least one storage device 210 include, but are not limited to, a subscriber identification module (SIM), read-only memory (ROM), flash memory, random access memory (RAM), compact disc read-only memory (CD-ROM), digital versatile disc ROM (DVD-ROM), Blu-ray® disc ROM (BD-ROM), magnetic tape, hard disk, optical data storage device, non-volatile storage device, and non-temporary computer-readable media (e.g., tangible media). At least one communication interface device 220 is preferably at least one transceiver and is used to transmit and receive signals (e.g., data, messages and / or packets) based on the processing results of at least one processing circuit 200.

[0046] Figure 3 is a flowchart of process 30 according to one embodiment of the present disclosure. Process 30 may be used by a communication device (for example, communication device 16 in Figure 1 or communication device 20 in Figure 2) to process communication resources. Process 30 may be compiled into program code 214 and includes the following steps 300 to 310.

[0047] Step 300 is to begin.

[0048] In step 302, first information related to a specific mode is received from the network.

[0049] In step 304, when it is decided to operate in a specific mode, the first message is sent to the network.

[0050] In step 306, after sending the first message, the system receives a first signaling signal from the network via the primary channel indicating the first channel.

[0051] In step 308, after receiving the first signaling, the first channel is applied to communicate with the network.

[0052] Step 310 is the end.

[0053] According to process 30, the communication device receives first information related to a particular mode from the network (e.g., via the primary CH). The network may be network 14 in Figure 1 or communication device 20 in Figure 2, but is not limited herein. Next, when the communication device decides to operate in a particular mode (e.g., to enable / enter / support a particular mode), it sends a first message to the network (e.g., via the primary CH). After sending the first message, the communication device receives a first signaling from the network via the primary CH indicating a first CH (e.g., resources (units) for the first CH). After receiving the first signaling, the communication device applies the first CH to communicate with the network (e.g., starts operation) (e.g., based on the first signaling). That is, when the communication device decides to operate in a particular mode, the network indicates a new CH, such as the first CH, to the communication device. The communication device performs communication with the network by applying the first CH. Thus, channel utilization efficiency can be improved.

[0054] The implementation of process 30 is not limited to the above description. The following embodiments may be applied to implement process 30.

[0055] In one embodiment, the specific mode is a dynamic subchannel / subband operation (DSO) mode. In one embodiment, when the communication device activates the specific mode, it transmits a second signaling to the network via the primary channel indicating the activation of the specific mode. The network then transmits first information to the communication device in response to the second signaling.

[0056] In one embodiment, when a controller (for example, controller 12 in Figure 1 or communication device 20 in Figure 2) activates a particular mode, it transmits a second signaling signal to the network via the primary channel. The network then transmits first information to the communication device in response to the second signaling signal.

[0057] In one embodiment, when the network activates a particular mode, it transmits first information to the communication device. In this case, the network does not receive a second signaling from the communication device or controller, but directly notifies the communication device (of the first information / about the first information).

[0058] In one embodiment, the first information includes at least one of at least one location of at least one nonprimary channel and at least one bandwidth of at least one nonprimary channel. In one embodiment, at least one nonprimary channel is, but is not limited herein, at least one polling-based multistation DSO (PMD) channel. In one embodiment, the first information includes at least one of a first time (e.g., a timestamp) for entering a particular mode, a second time (e.g., a timestamp) for sending a first message, and a third time (e.g., a timestamp) for sending data for channel assignment (e.g., a reassignment message). In one embodiment, the first information is received after the network has acquired the primary channel and the first channel over a certain duration (e.g., a transmit opportunity (TXOP)).

[0059] In one embodiment, the communication device receives second information related to a particular mode from the network (e.g., via the primary channel). In one embodiment, the second information includes at least one of the start time of the particular mode and the duration of the particular mode. In one embodiment, the second information relates to at least one of the initial control frame (ICF) (e.g., buffer state report pole (BSRP), multi-user transmission request (MU-RTS)), and immediate response (IR). In one embodiment, the second information is included in the first information or included in the first signaling.

[0060] In one embodiment, the communication device determines whether or not it should operate in a specific mode (for example, to enable a particular mode) based on first information. In another embodiment, the communication device determines whether or not it should operate in a specific mode based on data characteristics (for example, priority).

[0061] In one embodiment, when the communication device decides to disable operation in a particular mode, it ignores (e.g., drops) the first information (e.g., until it receives the next first information related to the next particular mode). The next first information can refer to examples of the first information, which are not described herein for brevity. In one embodiment, the next particular mode is started later than the particular mode.

[0062] In one embodiment, when a communication device decides to disable operation in a particular mode, it performs at least one of the following actions: ignoring the first information (e.g., disabling decoding) until it receives the next first information related to the next particular mode; disabling the transmission of the first message to the network via the primary CH; and applying (or continuing to apply) the primary CH to communicate with the network.

[0063] In one embodiment, when a communication device decides to operate in a specific mode (for example, to enable a particular mode), it performs at least one of the following: switching to the specific mode; performing a measurement on at least one non-primary channel and generating (e.g., acquiring) a measurement result; and generating a first message containing the measurement result. For example, the first communication device may perform a measurement on at least one first non-primary channel, and the second communication device may perform a measurement on at least one second non-primary channel, and the at least one first non-primary channel and the at least one second non-primary channel may be partially different.

[0064] In one embodiment, the first channel is a non-primary channel (e.g., a PMD channel). In one embodiment, the first channel is comprised of at least one non-primary channel. In one embodiment, the first channel is determined based on a first message (e.g., by the network). In one embodiment, the first channel is determined based on measurement results (e.g., by the network).

[0065] In one embodiment, the first signaling is initiated by the network, initiated / triggered by a communication device based on a first action message transmitted by the communication device, or initiated / triggered by a controller based on a second action message transmitted by the controller. In one embodiment, the first signaling is associated with at least one of ICF and IR.

[0066] In one embodiment, the communication device switches from the primary channel to the first channel based on a first signaling. In one embodiment, after switching from the primary channel to the first channel, the communication device applies the first channel to communicate with the network. In one embodiment, step 308 includes sending a second message to the network via the first channel (for example, in response to the first signaling). In one embodiment, the communication device switches back to the primary channel based on a time constraint (for example, at the end of a particular mode or timer). In one embodiment, the communication device may switch back to the primary channel after receiving instructions from the network.

[0067] In one embodiment, the primary channel and the first channel are acquired by the network over a certain duration (e.g., a transmission opportunity (TXOP)). In one embodiment, at least one of the primary channel (e.g., a resource in the primary channel) and the first channel (e.g., a resource in the first channel) is allocated to the communication device by the network in a non-overlapping manner. For example, the primary channel and the non-primary channel (e.g., the first channel) are not allocated to the communication device simultaneously. In one embodiment, the bandwidth of the primary channel is one of 20 megahertz (MHz), 40 MHz, 80 MHz, and 160 MHz. In one embodiment, the bandwidth of the first channel is one of 20 MHz, 40 MHz, 80 MHz, 160 MHz, and 320 MHz. The bandwidth of the resource in the first channel is one of 20 MHz, 40 MHz, 80 MHz, and 160 MHz.

[0068] In one embodiment, the primary channel and the first channel may be associated with a single network (e.g., a service provided by a single access point). In one embodiment, the primary channel and the first channel may be within a single frequency band (e.g., 2.4 GHz, 5 GHz, 6 GHz, 42 GHz, etc.).

[0069] In another embodiment, the primary channel and the first channel may be in different frequency bands. For example, the primary channel may be in the 5 GHz band and the first channel in the 2.4 GHz band.

[0070] Figure 4 is a flowchart of process 40 according to one embodiment of the present disclosure. Process 40 may be used in a network (e.g., network 14 in Figure 1 or communication device 20 in Figure 2) that communicates with at least one communication device (e.g., communication device 16 in Figure 1 or communication device 20 in Figure 2) to process resources for communication. Process 40 may be compiled into program code 214 and includes the following steps 400 to 408.

[0071] Step 400 is to begin.

[0072] In step 402, first information related to a specific mode is transmitted to the communication device.

[0073] In step 404, after receiving the first message from the communication device, the first signaling indicating the first channel is transmitted to the communication device via the primary channel.

[0074] In step 406, after transmitting the first signaling, the first channel is applied to communicate with the communication device.

[0075] Step 408 is complete.

[0076] According to process 40, the network transmits first information related to a particular mode (e.g., via the primary CH) to the communication device. The communication device may be, but is not limited herein, communication device 16 in Figure 1 or communication device 20 in Figure 2. Next, the network receives a first message (e.g., related to the activation of a particular mode) from the communication device and transmits a first signaling indicating the first CH via the primary CH to the communication device. After transmitting the first signaling, the network applies the first CH to communicate with the communication device. That is, the network performs communication with the communication device by indicating a new CH such as the first CH and applying the first CH. Thus, channel utilization efficiency can be improved.

[0077] The implementation of process 40 is not limited to the above description. Embodiments of process 30 may also be applied to process 40 and are not described herein for the sake of brevity. Furthermore, the following embodiments may be applied to implement process 40.

[0078] In one embodiment, the network performs at least one of the following actions when a particular mode is activated or when a second signaling is received: switching to a particular mode and generating first information. The first information and the second signaling can refer to process 30, which are not described herein for brevity.

[0079] In one embodiment, after receiving a first message from a communication device, the network performs at least one of the following operations: assigning a first channel to the communication device (for example, based on the first message or measurement results); and generating a first signaling indicating the first channel. The measurement results can be seen in process 30, which are not described herein for brevity.

[0080] In other words, the network (e.g., AP) identifies at least one specific communication device (e.g., STA) and invites it to participate / operate in a specific mode (e.g., switch to the corresponding indicated channel).

[0081] Figure 5 is a sequence diagram of process 50 according to one embodiment of the present disclosure. Process 50 includes a communication device CM and a network NW. In one embodiment, the network NW activates a specific mode. In one embodiment, the communication device CM or controller (not shown in Figure 5) activates a specific mode and sends a second signaling to the network NW indicating the activation of the specific mode. Two of the above embodiments are not shown in Figure 5 for brevity. In step 500, the network NW activates / enables (e.g., switches) a specific mode in response to, for example, activating a specific mode or receiving a second signaling. In step 502, the network NW generates first information related to the specific mode. In step 504, the network NW sends the first information to the communication device CM.

[0082] Please refer to Figure 6 in combination with Figure 5. Figure 6 is a flowchart of process 60 according to one embodiment of the present disclosure, showing the operation of the communication device CM after step 504 in Figure 5. In step 602, the communication device CM receives first information from the network NW. Step 602 corresponds to step 504 in Figure 5. In step 604, the communication device CM decides whether or not to operate in a specific mode. Next, the communication device CM executes steps 610 to 616 when it decides to operate in a specific mode, and steps 606 to 608 when it decides to disable operation in a specific mode.

[0083] In step 606, the communication device CM continues to apply the primary channel to communicate with the network NW. In step 608, the communication device CM ignores the first information. In step 610, the communication device CM switches to a specific mode. In step 612, the communication device CM performs a measurement on at least one non-primary channel to generate a measurement result. In step 614, the communication device CM generates a first message containing the measurement result. In step 616, the communication device CM sends the first message to the network NW.

[0084] In the following diagram, blocks included in a channel represent communication operations performed over the channel. For example, resources (e.g., resource units in a channel) are included in the area indicated by the block. Data transmission and / or reception are performed over the resources included in the channel. Resources may be indicated / allocated by the network (e.g., for scheduled transmissions). Resources may be acquired / accessed by communication devices through contention-based channel access using a distributed control mechanism (DCF).

[0085] Refer to Figure 7 in conjunction with Figure 6. Figure 7 is a schematic diagram of a primary channel P_CH and non-primary channels NP_CH1 to NP_CH4 according to one embodiment of the present disclosure. In Figure 7, the primary channel P_CH and non-primary channels NP_CH1 to NP_CH4 correspond to the time axis T and may be the primary channel and at least one non-primary channel in Figure 6. Block 700 in the primary channel P_CH, block 702 in the non-primary channels NP_CH1 to NP_CH4, and block 704 in the primary channel P_CH correspond to steps 602, 612, and 616 in Figure 6, respectively. In detail, block 700 represents the communication device receiving first information related to a particular mode from the network. Block 702 represents the communication device performing a measurement on at least one of the non-primary channels NP_CH1 to NP_CH4 to generate a measurement result when it has decided to operate in a particular mode. Block 704 represents the communication device sending a first message to the network.

[0086] Refer to Figure 8 in conjunction with Figure 6. Figure 8 is a sequence diagram of process 80 according to one embodiment of the present disclosure, showing the operation of the communication device CM and network NW after step 616 in Figure 6. In step 800, the communication device CM sends a first message to the network NW. Step 800 corresponds to step 616 in Figure 6. In step 802, the network NW assigns a first channel (e.g., a non-primary channel) to the communication device CM based on the first message. In step 804, the network NW generates a first signaling indicating the first channel. In step 806, the network NW sends the first signaling to the communication device CM. In step 808, the communication device CM switches from the primary channel to the first channel based on the first signaling. For example, the communication device CM transmits messages (e.g., initial control response (ICR), immediate response (IR)) corresponding to the first signaling (e.g., in response to the first signaling) via the first channel (e.g., via resources contained in the first channel). In step 810, the communication device CM applies the first channel to communicate with the network NW.

[0087] Refer to Figure 9A in combination with Figure 8. Figure 9A is a schematic diagram of primary channel P_CH and non-primary channels NP_CH1 to NP_CH4 according to one embodiment of the present disclosure. Figure 8 shows an example of one communication device, and Figure 9A shows an example of multiple communication devices CM1 to CM6. Communication devices CM1 to CM4 decide to operate in a specific mode, and communication devices CM5 to CM6 decide to disable operation in a specific mode. Each of communication devices CM1 to CM4 may be a communication device CM in Figure 8.

[0088] In Figure 9A, the primary channel P_CH and non-primary channels NP_CH1 to NP_CH4 correspond to the time axis T. The primary channel P_CH may also be the primary channel in Figure 8. Each of the non-primary channels NP_CH1 to NP_CH4 may also be the first channel in Figure 8. Blocks 900_1, 900_2, 900_3, and 900_4 in the primary channel P_CH represent communication operations performed by communication devices CM1 to CM4, respectively. For example, blocks 900_1, 900_2, 900_3, and 900_4 correspond to step 800 in Figure 8. Communication devices CM1 to CM4 each send their individual first messages to the network NW. The first message corresponding to block 900_2 may include the measurement results of NP_CH1, NP_CH2, and NP_CH4 obtained by communication device CM2. Block 902 in the primary channel P_CH corresponds to step 806 in Figure 8. Communication devices CM1 to CM4 receive a first signaling signal from the network NW. The first signaling signal indicates a non-primary channel NP_CH1 for communication device CM1, a non-primary channel NP_CH2 for communication device CM2, a non-primary channel NP_CH3 for communication device CM3, and a non-primary channel NP_CH4 for communication device CM4. The primary channel and primary band may be used interchangeably. The non-primary channel may be a subband.

[0089] After receiving the first signal from the network NW, communication devices CM1 to CM4 switch from the primary channel P_CH to the non-primary channels NP_CH1 to NP_CH4 (for example, at the same time).

[0090] In Figure 9A, blocks 904_1 in nonprimary channel NP_CH1, 904_2 in nonprimary channel NP_CH2, 904_3 in nonprimary channel NP_CH3, and 904_4 in nonprimary channel NP_CH4 represent communication operations performed by communication devices CM1 to CM4, respectively. For example, blocks 904_1, 904_2, 904_3, and 904_4 correspond to step 810 in Figure 8. Communication devices CM1 to CM4 each apply nonprimary channels NP_CH1 to NP_CH4 to communicate with the network NW. Communication devices CM1 to CM4 each send their individual messages (e.g., corresponding to the first signaling) to the network NW (e.g., at the same time). Individual messages sent by a communication device (e.g., CM1) may be sent via resources contained in the area indicated by a block (e.g., 904_1).

[0091] Furthermore, communication devices CM5-CM6, whose operation in a specific mode is disabled, continue to apply the primary channel P_CH to communicate with the network NW via contention-based channel access (or in sequence). For example, block 908_5 in the primary channel P_CH indicates that communication device CM5 is performing communication operations with the network NW, and block 908_6 in the primary channel P_CH indicates that communication device CM6 is performing communication operations with the network NW.

[0092] Refer to Figure 9B in conjunction with Figure 8. Figure 9B is a schematic diagram of primary channel P_CH and non-primary channels NP_CH1 to NP_CH4 according to one embodiment of the present disclosure. Figure 8 shows an example of one communication device, and Figure 9B shows an example of multiple communication devices CM1 to CM6. Communication devices CM1 to CM4 decide to operate in a specific mode, and communication devices CM5 to CM6 decide to disable operation in a specific mode. Each of communication devices CM1 to CM4 may be a communication device CM in Figure 8.

[0093] In Figure 9B, the primary channel P_CH and non-primary channels NP_CH1 to NP_CH4 correspond to the time axis T. The primary channel P_CH may also be the primary channel in Figure 8. Each of the non-primary channels NP_CH1 to NP_CH4 may also be the first channel in Figure 8. Blocks 900_1, 900_2, 900_3, and 900_4 in the primary channel P_CH represent communication operations performed by communication devices CM1 to CM4, respectively. For example, blocks 900_1, 900_2, 900_3, and 900_4 correspond to step 800 in Figure 8. Communication devices CM1 to CM4 each transmit their individual first messages to the network NW. The first message corresponding to block 900_2 may include measurement results of non-primary channels NP_CH1, NP_CH2, and NP_CH4 acquired by communication device CM2. Block 902 in the primary channel P_CH corresponds to step 806 in Figure 8. Communication devices CM1 to CM4 receive a first signaling from the network NW. The first signaling indicates a non-primary channel NP_CH1 for communication device CM1, a non-primary channel NP_CH2 for communication device CM2, a non-primary channel NP_CH3 for communication device CM3, and a non-primary channel NP_CH4 for communication device CM4. The primary channel and primary band may be used interchangeably. The non-primary channel may be a subband.

[0094] After receiving the first signal from the network NW, communication devices CM1 to CM4 switch from the primary channel P_CH to the non-primary channels NP_CH1 to NP_CH4 (for example, at the same time).

[0095] In Figure 9B, blocks 906_1 in nonprimary channel NP_CH1, 906_2 in nonprimary channel NP_CH2, 906_3 in nonprimary channel NP_CH3, and 906_4 in nonprimary channel NP_CH4 represent communication operations performed by communication devices CM1 to CM4, respectively. For example, blocks 906_1, 906_2, 906_3, and 906_4 correspond to step 810 in Figure 8. Communication devices CM1 to CM4 each apply nonprimary channels NP_CH1 to NP_CH4 to communicate with the network NW. Before sending or receiving messages / data over the channel, the communication device may perform carrier sensing on the channel (for example, at the same time).

[0096] When a channel is idle, unoccupied, or uninterrupted, a communication device (e.g., communication device CM2) accesses the channel using competition-based channel access (e.g., DCF, Hybrid Control Mechanism (HCF), Extended Distributed Channel Access (EDCA)) to send or receive messages / data (e.g., sending individual messages corresponding to the first signaling).

[0097] When a channel is busy, occupied, or interfered with (e.g., in the hatched blocks of non-primary channels NP_CH1, NP_CH3, and NP_CH4), the communication devices (e.g., communication devices CM1, CM3, and CM4) postpone their transmission or reception. The communication devices then access the channel using contention-based channel access and perform message / data transmission or reception (e.g., transmission of individual messages corresponding to the first signaling). Individual messages transmitted by the communication device (e.g., communication device CM1) may be transmitted via resources contained in the area indicated by a block (e.g., block 906_1). Note that (data) transmission and / or reception may also be performed corresponding to a block (e.g., 906_2), but are not shown in this diagram for brevity.

[0098] Furthermore, communication devices CM5-CM6, whose operation in a specific mode is disabled, continue to apply the primary channel P_CH to communicate with the network NW via contention-based channel access (or in sequence). For example, block 908_5 in the primary channel P_CH indicates that communication device CM5 is performing communication operations with the network NW, and block 908_6 in the primary channel P_CH indicates that communication device CM6 is performing communication operations with the network NW.

[0099] Please refer to Figure 9C in conjunction with Figure 8. Figure 9C is a schematic diagram of primary channel P_CH and non-primary channels NP_CH1 to NP_CH4 according to one embodiment of the present disclosure. Figure 8 shows an example of one communication device, and Figure 9C shows an example of multiple communication devices CM1 to CM6. Communication devices CM1 to CM4 decide to operate in a specific mode, and communication devices CM5 to CM6 decide to disable operation in a specific mode. Each of communication devices CM1 to CM4 may be a communication device CM in Figure 8.

[0100] In Figure 9C, the primary channel P_CH and non-primary channels NP_CH1 to NP_CH4 correspond to the time axis T. The primary channel P_CH may also be the primary channel in Figure 8. Each of the non-primary channels NP_CH1 to NP_CH4 may also be the first channel in Figure 8. Blocks 900_1, 900_2, 900_3, and 900_4 in the primary channel P_CH represent communication operations performed by communication devices CM1 to CM4, respectively. For example, blocks 900_1, 900_2, 900_3, and 900_4 correspond to step 800 in Figure 8. Communication devices CM1 to CM4 each send their individual first messages to the network NW. The first message corresponding to block 900_2 may include the measurement results of NP_CH1, NP_CH2, and NP_CH4 acquired by communication device CM2. Block 902 in the primary channel P_CH corresponds to step 806 in Figure 8. Communication devices CM1 to CM4 receive a first signaling from the network NW. The first signaling indicates a non-primary channel NP_CH1 for communication device CM1, a non-primary channel NP_CH2 for communication device CM2, a non-primary channel NP_CH3 for communication device CM3, and a non-primary channel NP_CH4 for communication device CM4. The primary channel and primary band may be used interchangeably. The non-primary channel may be a subband.

[0101] After receiving the first signal from the network NW, communication devices CM1 to CM4 switch from the primary channel P_CH to the non-primary channels NP_CH1 to NP_CH4 (for example, at the same time).

[0102] In Figure 9C, blocks 908_1 in nonprimary channel NP_CH1, 908_2 in nonprimary channel NP_CH2, 908_3 in nonprimary channel NP_CH3, and 908_4 in nonprimary channel NP_CH4 represent communication operations performed by communication devices CM1 to CM4, respectively. For example, blocks 908_1, 908_2, 908_3, and 908_4 correspond to step 810 in Figure 8. Communication devices CM1 to CM4 each apply nonprimary channels NP_CH1 to NP_CH4 to communicate with the network NW. Communication devices CM1 to CM4 each send their individual messages (e.g., corresponding to the first signaling) to the network NW (e.g., at the same time) (e.g., within a time interval, either without carrier sense or using contention-based channel access). Individual messages transmitted by a communication device (e.g., communication device CM1) may be transmitted via resources contained in the region indicated by a block (e.g., block 908_1). Resources may be allocated by the network NW within a time interval.

[0103] After a time interval, blocks 910_1 in nonprimary channel NP_CH1, 910_2 in nonprimary channel NP_CH2, 910_3 in nonprimary channel NP_CH3, and 910_4 in nonprimary channel NP_CH4 represent communication operations performed by communication devices CM1 to CM4, respectively. For example, blocks 910_1, 910_2, 910_3, and 910_4 correspond to step 810 in Figure 8. Communication devices CM1 to CM4 each apply nonprimary channels NP_CH1 to NP_CH4 to communicate with the network NW. Before sending or receiving messages / data over the channel, the communication device may perform carrier sensing on the channel (for example, at the same time).

[0104] When a channel is idle, unoccupied, or uninterrupted, a communication device (e.g., communication device CM2) accesses the channel using contention-based channel access (e.g., DCF, HCF, EDCA) to send or receive messages / data. Message / data transmission may exclude individual messages corresponding to the first signaling.

[0105] When a channel is busy, occupied, or interfered with (e.g., a hatched block in non-primary channels NP_CH1, NP_CH3, and NP_CH4), the communication devices (e.g., communication devices CM1, CM3, and CM4) postpone their transmission or reception. The communication devices then access the channel using contention-based channel access and perform message / data transmission or reception. Message / data transmission may exclude individual messages corresponding to the first signaling. Note that (data) transmission and / or reception may be performed in accordance with blocks (e.g., block 906_2), but are not shown in this diagram for brevity.

[0106] Furthermore, communication devices CM5-CM6, whose operation in a specific mode is disabled, continue to apply the primary channel P_CH to communicate with the network NW via contention-based channel access (or in sequence). For example, block 908_5 in the primary channel P_CH indicates that communication device CM5 is performing communication operations with the network NW, and block 908_6 in the primary channel P_CH indicates that communication device CM6 is performing communication operations with the network NW.

[0107] Figure 10 is a flowchart of process 100 according to one embodiment of the present disclosure. Process 100 may be used by a communication device (for example, communication device 16 in Figure 1 or communication device 20 in Figure 2) to process communication resources. Process 100 may be compiled into program code 214 and includes the following steps 1000 to 1006.

[0108] Step 1000 is to begin.

[0109] Step 1002 involves performing at least one communication operation with the network via the first channel.

[0110] In step 1004, the system operates on the second channel based on at least one of the following: instructions, time constraints, and interference conditions.

[0111] Step 1006 is the end.

[0112] According to process 100, the communication device performs at least one communication operation with the network via the first CH. The network may be, but is not limited herein, network 14 in Figure 1 or communication device 20 in Figure 2. Next, the communication device operates on the second CH (e.g., starts operation) based on at least one of instructions, time constraints, and interference conditions. That is, the communication device dynamically allocates CHs (e.g., resources (units) for CHs) to communicate with the network. Thus, channel utilization efficiency can be improved.

[0113] The implementation of process 100 is not limited to the above description. The following embodiments may be applied to implement process 100.

[0114] In one embodiment, the instruction is determined (e.g., generated) by a communication device. In one embodiment, the communication device transmits the instruction to the network via a first channel. In one embodiment, the instruction is transmitted to the network after the communication device receives an allocation inquiry message from the network. For example, the instruction is transmitted to the network via a resource unit (e.g., 20 MHz) included in the first channel (e.g., 80 MHz).

[0115] In one embodiment, the communication device transmits an allocation request to the network (for example, via the first channel). In one embodiment, after the communication device transmits the allocation request, an allocation inquiry message is received (for example, by the communication device via the first channel).

[0116] In one embodiment, the instruction indicates at least one of data information and role intention. In one embodiment, the data information indicates at least one of the amount of data (to be transmitted) and the traffic type of the data (e.g., priority). In one embodiment, the role intention indicates one of CH reduction, CH reservation, and CH extension. A role intention indicating CH reduction may be equivalent to no instruction / transmission for CH reservation and CH extension. A traffic type with a larger amount and / or higher priority may be equivalent to an intention for CH extension. A traffic type with a smaller amount and / or lower priority may be equivalent to an intention for CH reduction.

[0117] In one embodiment, the communication device determines its role intent in response to receiving an assignment inquiry message. In one embodiment, the step of determining the role intent includes at least one of the following: determining whether or not a CH expansion is required; and determining whether or not a first CH can be provided. In one embodiment, the step of determining the role intent includes at least one of the following: determining a role intent indicating a CH reduction when the communication device does not require a CH expansion and / or can provide a first CH; determining a role intent indicating a CH reservation when the communication device does not require a CH expansion and / or cannot provide a first CH; and determining a role intent indicating a CH expansion when the communication device requires a CH expansion. For example, the communication device may not require a CH expansion when it decides to operate in power-saving mode.

[0118] In one embodiment, the communication device receives a first assignment message from the network via the first channel based on instructions. In one embodiment, the first assignment message indicates the second channel. In one embodiment, the first assignment message indicates the second channel to a single communication device (e.g., a communication device). In one other embodiment, the first assignment message indicates the second channel to multiple communication devices (e.g., a communication device and another communication device).

[0119] In one embodiment, the second CH is determined based on the instructions.

[0120] In one embodiment, the second channel is determined based on the measurement result of at least one channel acquired by the communication device. For example, the second channel is included in at least one channel (e.g., one of them). In one embodiment, the second channel is determined by the network. In one embodiment, the measurement result is included in the instruction or the previous message preceding the instruction. In one embodiment, the previous message is transmitted to the network via the primary channel.

[0121] In one embodiment, when an instruction indicates a channel reduction, the second channel is one of the primary channel, the first non-primary channel (e.g., a subband), and the second non-primary channel. In one embodiment, the first non-primary channel is included in the first channel and has a bandwidth narrower (or not wider) than the bandwidth of the first channel. In one embodiment, the second non-primary channel is not included in the first channel and has a bandwidth narrower than the bandwidth of the first channel. In one embodiment, the first non-primary channel or the second non-primary channel is indicated by a second assignment message received from the network via the first channel. In one embodiment, the communication device determines the first non-primary channel or the second non-primary channel. In one embodiment, when the communication device determines (e.g., prefers) a channel reduction, it may determine (e.g., anticipate) that the second channel is the primary channel or the first non-primary channel (e.g., whether or not an explicit instruction is received). For example, when the communication device determines (e.g., prefers) a channel reduction, it determines the first non-primary channel. In one embodiment, when the communication device indicates a channel reduction and / or a lower traffic type, the instruction transmitted by the communication device may (further) indicate a target channel (e.g., a narrower channel included in the primary channel or first channel). Based on the received instruction, the network understands that the communication device may / will switch to the target channel.

[0122] In one embodiment, when the instruction indicates a CH extension, the second CH is either the first CH or includes a third non-primary CH. In one embodiment, the second CH has a bandwidth wider (or not narrower) than the bandwidth of the first CH. In one embodiment, the third non-primary CH is either the entire available CH including the first CH or an additional available CH other than the first CH.

[0123] In one embodiment, when the instruction indicates a channel reservation, the second channel is the first channel. In one embodiment, when the communication device determines (e.g., makes a preference) a channel reservation, it may determine (e.g., anticipate) that the second channel is the first channel (regardless of whether an explicit instruction is received, for example).

[0124] In one embodiment, the time constraint is determined by the communication device or indicated by the network for at least one communication device. In one embodiment, at least one(s) of the communication devices operate in a specific mode. In one embodiment, the time constraint is received from the network via a first channel. In one embodiment, the time constraint is indicated by an assignment message received from the network. In one embodiment, the time constraint indicates at least one of a time and a timer. For example, at least one(s) of the communication devices begin operating on the channel corresponding to the time (e.g., switch to the channel corresponding to the time). In one embodiment, the communication device switches to the primary channel based on the time constraint (e.g., at the end time of a specific mode or timer).

[0125] In one embodiment, the first CH is the fourth non-primary CH.

[0126] In one embodiment, the primary channel, the first channel, and the second channel are acquired by the network over a certain duration (e.g., TXOP). In one embodiment, at least one of the primary channel (resources), the first channel (resources), and the second channel (resources) is allocated to the communication device by the network in a non-overlapping manner. For example, the primary channel and non-primary channels (e.g., the first channel and the second channel) are not allocated to the communication device simultaneously.

[0127] In one embodiment, the communication device switches from the primary channel to the first channel and communicates with the network. In one embodiment, the communication device receives a third assignment message from the network via the primary channel indicating the first channel. In one embodiment, after switching to (or operating on) the first channel, the communication device performs at least one communication operation with the network.

[0128] In one embodiment, the communication device operates on the second channel when operating in a specific mode. In one embodiment, the specific mode is the DSO mode.

[0129] In one embodiment, step 1004 includes a step of switching from the first channel to the second channel to communicate with the network. In one embodiment, the step of switching from the first channel to the second channel includes at least one of an operation to determine whether the second channel is the primary channel and an operation to determine whether the second channel is the first channel. In one embodiment, the step of switching from the first channel to the second channel includes at least one of an operation to switch from the first channel to the second channel when the second channel is neither the primary channel nor the first channel, an operation to continue applying the first channel to communicate with the network when the second channel is the first channel, and an operation to switch from the first channel to the primary channel when the second channel is the primary channel.

[0130] In one embodiment, the bandwidth of the primary channel is one of 20 megahertz (MHz), 40 MHz, 80 MHz, and 160 MHz. In one embodiment, the bandwidth of the first channel is one of 20 MHz, 40 MHz, 80 MHz, 160 MHz, and 320 MHz. In one embodiment, the bandwidth of the second channel is one of 20 MHz, 40 MHz, 80 MHz, 160 MHz, and 320 MHz.

[0131] It should be noted that process 100 may be a subsequence operation of process 30. Therefore, embodiments of process 30 may be applied to process 100 and are not described herein for the sake of brevity.

[0132] Figure 11 is a flowchart of process 110 according to one embodiment of the present disclosure. Process 110 may be used in a network (e.g., network 14 in Figure 1 or communication device 20 in Figure 2) that communicates with at least one communication device (e.g., communication device 16 in Figure 1 or communication device 20 in Figure 2) to process resources for communication. Process 110 may be compiled into program code 214 and includes the following steps 1100 to 1106.

[0133] Step 1100 is to begin.

[0134] Step 1102 involves performing at least one communication operation with one of the communication devices via the first channel.

[0135] In step 1104, the system operates on the second channel based on at least one of the following: instructions, time constraints, and interference conditions.

[0136] Step 1106 is the end.

[0137] According to process 110, the network performs at least one communication operation with one of at least one communication devices via the first CH. The communication device may be, but is not limited herein, communication device 16 in Figure 1 or communication device 20 in Figure 2. Next, the network operates on the second CH (e.g., starts operation) based on at least one of instructions, time constraints, and interference conditions. That is, the network dynamically allocates CHs (e.g., resources (units) for CHs) to communicate with the communication devices. Thus, channel utilization efficiency can be improved.

[0138] The implementation of process 110 is not limited to the above description. Embodiments of process 100 may be applied to process 110 and are not described herein for brevity. Furthermore, the following embodiments may be applied to implement process 110.

[0139] In one embodiment, after receiving instructions from a communication device, the network performs at least one of the following operations: assigning (or reassigning) the second channel to the communication device (for example, based on at least one of instructions, time constraints, and interference conditions); and generating a first assignment message indicating the second channel. The instructions, second channel, and first assignment message can refer to process 100 and are not described herein for brevity.

[0140] It should be noted that process 110 may be a subsequence operation of process 40. Embodiments of process 40 may be applied to process 110 and are not described herein for the sake of brevity.

[0141] Figure 12 is a sequence diagram of process 120 according to one embodiment of the present disclosure. Process 120 includes a communication device CM and a network NW, and process 120 may be a subsequence operation of process 80. In step 1200, the network NW sends an allocation inquiry message to the communication device CM via the first CH. In step 1202, the communication device CM determines a role intent indicating one of the following: CH reduction, CH reservation, and CH expansion. In step 1204, the communication device CM generates an instruction including the role intent. In step 1206, the communication device CM sends the instruction to the network NW via the first CH. In step 1208, the network NW allocates (or reassigns) the second CH to the communication device CM based on the instruction. In step 1210, the network NW generates a first allocation message indicating the second CH. In step 1212, the network NW sends the first allocation message to the communication device CM via the first CH. In step 1214, the communication device CM switches from the first channel to the second channel based on the first assigned message and communicates with the network. In step 1216, the communication device CM switches from the second channel to the primary channel based on time constraints.

[0142] In process 120, if the second channel is the primary channel, the communication device does not perform step 1216.

[0143] Please refer to Figure 13 in conjunction with Figure 12. Figure 13 is a flowchart of process 130 according to one embodiment of the present disclosure, and shows details of step 1202 in Figure 12. In step 1302, the communication device CM determines whether or not a CH expansion is required. Next, if the communication device CM determines that a CH expansion is required, it performs step 1304, and if it determines that a CH expansion is not required, it performs step 1306. In step 1304, the communication device CM determines the role intent to indicate a CH expansion. In step 1306, the communication device CM determines whether or not it can provide the first CH. Next, if the communication device CM determines that it can provide the first CH, it performs step 1308, and if it determines that it cannot provide the first CH, it performs step 1310. In step 1308, the communication device CM determines the role intent to indicate a CH reduction. In step 1310, the communication device CM determines the role intent to indicate a CH reservation.

[0144] Refer to Figure 14 in conjunction with Figure 12. Figure 14 is a flowchart of process 140 according to one embodiment of the present disclosure, and shows details of step 1214 in Figure 12. In step 1402, the communication device CM determines whether the second channel is the primary channel. Next, if the communication device CM determines that the second channel is the primary channel, it executes step 1404, and if it determines that the second channel is not the primary channel, it executes step 1406. In step 1404, the communication device CM switches from the first channel to the primary channel. In step 1406, the communication device CM determines whether the second channel is the first channel. Next, if the communication device CM determines that the second channel is the first channel, it executes step 1408, and if it determines that the second channel is not the first channel, it executes step 1410. In step 1408, the communication device CM continues to apply the first channel to communicate with the network NW. In step 1410, the communication device CM switches from the first channel to the second channel. Note that the communication device will indicate a channel expansion, but will continue to use the first channel if no additional channels are available.

[0145] Refer to Figure 15 in conjunction with Figure 14. Figure 15 is a schematic diagram of primary channel P_CH and non-primary channels NP_CH1 to NP_CH4 according to one embodiment of the present disclosure. In Figure 15, primary channel P_CH and non-primary channels NP_CH1 to NP_CH4 correspond to the time axis T. The communication device CM operates in a specific mode and applies non-primary channel NP_CH1 (e.g., block 1500). The communication device CM switches from non-primary channel NP_CH1 to primary channel P_CH (e.g., block 1502) (e.g., based on a first assignment message), which corresponds to step 1410 in Figure 14. In this case, the instruction (e.g., role intent) indicates a channel reservation.

[0146] Refer to Figure 16 in conjunction with Figures 8 and 14. Figure 16 is a schematic diagram of primary channel P_CH and non-primary channels NP_CH1 to NP_CH4 according to one embodiment of the present disclosure. In Figure 16, primary channel P_CH and non-primary channels NP_CH1 to NP_CH4 correspond to the time axis T. The communication device CM operates in a specific mode and applies primary channel P_CH (e.g., block 1604). The communication device CM switches from primary channel P_CH to non-primary channel NP_CH1 (e.g., block 1600). The communication device CM switches from non-primary channel NP_CH1 to primary channel P_CH (e.g., block 1602) (e.g., based on a first assignment message), which corresponds to step 1410 in Figure 14. For example, a first assignment message is received by the communication device CM from the network NW via non-primary channel NP_CH1 (e.g., block 1600). In this case, the instruction (e.g., role intent) indicates a CH reservation.

[0147] Refer to Figure 17 in conjunction with Figure 14. Figure 17 is a schematic diagram of primary CH P_CH and non-primary CH NP_CH1~NP_CH4 according to one embodiment of the present disclosure. In Figure 17, primary CH P_CH and non-primary CH NP_CH1~NP_CH4 correspond to the time axis T. The communication device CM operates in a specific mode and applies a combination of non-primary CH NP_CH1~NP_CH2 (e.g., block 1700). Note that the non-primary CH NP_CH1~NP_CH2 in this embodiment are continuous but are not limited herein. The communication device CM switches from a combination of non-primary CH NP_CH1~NP_CH2 (e.g., block 1702) (e.g., based on a first assignment message), which corresponds to step 1410 in Figure 14. In this case, the instruction (e.g., role intent) indicates a CH reduction.

[0148] Refer to Figure 18 in conjunction with Figures 8 and 14. Figure 18 is a schematic diagram of primary CH P_CH and non-primary CH NP_CH1~NP_CH4 according to one embodiment of the present disclosure. In Figure 18, primary CH P_CH and non-primary CH NP_CH1~NP_CH4 correspond to the time axis T. The communication device CM operates in a specific mode and applies primary CH P_CH (e.g., block 1804). The communication device CM switches from primary CH P_CH to non-primary CH NP_CH1~NP_CH2 (combination) (e.g., block 1800). Note that the non-primary CH NP_CH1~NP_CH2 in this embodiment are continuous but are not limited herein.

[0153] Please refer to Figure 23 in combination with Figures 12 and 14. Figure 23 is a schematic diagram of primary CH P_CH and non-primary CH NP_CH1~NP_CH4 according to one embodiment of the present disclosure. Figure 12 shows an example of one communication device, and Figure 23 shows an example of multiple communication devices CM1~CM6. Communication devices CM1~CM4 operate in a specific mode and apply non-primary CH NP_CH1~NP_CH4, respectively. Communication devices CM5~CM6 disable operation in a specific mode and apply primary CH P_CH. Furthermore, each of communication devices CM1~CM4 may be communication device CM in Figure 12.

[0154] In Figure 23, the primary channel P_CH and non-primary channels NP_CH1 to NP_CH4 correspond to the time axis T. Each of the primary channel P_CH and non-primary channels NP_CH1 to NP_CH4 may also be the primary channel and the first channel in Figure 12. In the case of communication device CM1, the first channel is the non-primary channel NP_CH1. In the case of communication device CM2, the first channel is the non-primary channel NP_CH2. In the case of communication device CM3, the first channel is the non-primary channel NP_CH3. In the case of communication device CM4, the first channel is the non-primary channel NP_CH4.

[0155] Blocks 2302_1 in non-primary channel NP_CH1, 2302_2 in non-primary channel NP_CH2, 2302_3 in non-primary channel NP_CH3, and 2302_4 in non-primary channel NP_CH4 represent communication operations performed by communication devices CM1 to CM4, respectively. For example, communication devices CM1 to CM4 each apply non-primary channels NP_CH1 to NP_CH4 to communicate with the network NW. A communication device (e.g., communication device CM1) may send an allocation request to the network NW. The allocation request may be sent via resources contained in the area indicated by a block (e.g., block 2302_1).

[0156] Blocks 2304 of non-primary channels NP_CH1 to NP_CH4 correspond to step 1200 in Figure 12. The network NW sends allocation inquiry messages to communication devices CM1 to CM4. Blocks 2306_1 in non-primary channel NP_CH1, 2306_2 in non-primary channel NP_CH2, 2306_3 in non-primary channel NP_CH3, and 2306_4 in non-primary channel NP_CH4 correspond to step 1206 in Figure 12. Communication devices CM1 to CM4 each send their instructions to the network NW. The instruction from communication device CM_1 may indicate channel reservation. The instructions from communication devices CM2 to CM3 may indicate channel reduction. The instruction from communication device CM4 may indicate channel expansion. Note that (data) transmission and / or reception may be performed corresponding to blocks (e.g., block 2302_2), but are not shown in this figure for brevity.

[0157] Block 2308 of non-primary channels NP_CH1 to NP_CH4 corresponds to step 1212 in Figure 12. The network NW sends a first assignment message. The first assignment message indicates a combination of non-primary channels NP_CH2 to NP_CH4 (i.e., all available channels) or non-primary channels NP_CH2 to NP_CH3 (i.e., additional available channels) for communication device CM4. The first assignment message may optionally / further indicate non-primary channel NP_CH1 for communication device CM1. The first assignment message may optionally / further indicate primary channels P_CH for communication devices CM2 to CM3. Thus, communication device CM1 continues to apply non-primary channel NP_CH1 (e.g., block 2310_1), which corresponds to step 1408 in Figure 14. Communication devices CM2 and CM3 switch to primary channel P_CH (e.g., blocks 2310_2 and 2310_3), which corresponds to step 1404 in Figure 14. Communication device CM4 switches to non-primary channels NP_CH2 to NP_CH4 (a combination) (e.g., block 2310_4), which corresponds to step 1410 in Figure 14. Because communication devices CM2 and CM3 switch to primary channel P_CH, communication devices CM2, CM3 and CM5, CM6 apply primary channel P_CH (e.g., blocks 2310_2, 2310_3, 2310_5 and 2310_6) via contention-based channel access (or in sequence).

[0158] Next, communication devices CM1 and CM4 switch to primary CH P_CH (e.g., blocks 2312_1 and 2312_4) at the end of a specific mode, which corresponds to step 1216 in Figure 12. As communication devices CM1 and CM4 switch to primary CH P_CH, communication devices CM1 to CM6 apply primary CH P_CH (e.g., blocks 2312_1 to 2312_6) by contention-based channel access (or in sequence).

[0159] Figure 23 may also represent the subsequence status of Figure 9A (or Figures 9B and 9C). For example, block 904_4 corresponds to block 2302_4.

[0160] Please refer to Figure 24 in combination with Figures 12 and 14.

Figure 12 shows an example of one communication device, and Figure 24 shows an example of multiple communication devices CM1~CM5. Communication devices CM1~CM4 operate in a specific mode and apply non-primary CH NP_CH1~NP_CH4, respectively. Communication device CM5 disables operation in a specific mode and applies primary CH P_CH. Furthermore, each of communication devices CM1~CM4 may be communication device CM in Figure 12.

[0161] In Figure 24, the primary channel P_CH and non-primary channels NP_CH1 to NP_CH4 correspond to the time axis T. Each of the primary channel P_CH and non-primary channels NP_CH1 to NP_CH4 may also be the primary channel and the first channel in Figure 12. For communication device CM1, the first channel is the non-primary channel NP_CH1. For communication device CM2, the first channel is the non-primary channel NP_CH2. For communication device CM3, the first channel is the non-primary channel NP_CH3. For communication device CM4, the first channel is the non-primary channel NP_CH4.

[0162] Blocks 2402_1 in non-primary channel NP_CH1, 2402_2 in non-primary channel NP_CH2, 2402_3 in non-primary channel NP_CH3, and 2402_4 in non-primary channel NP_CH4 represent communication operations performed by communication devices CM1 to CM4, respectively. For example, communication devices CM1 to CM4 each apply non-primary channels NP_CH1 to NP_CH4 to communicate with the network NW. A communication device (e.g., communication device CM1) may send instructions to the network NW. Instructions may be sent via resources contained in the area indicated by a block (e.g., block 2402_1).

[0163] Block 2404 of non-primary channels NP_CH1 to NP_CH4 corresponds to step 1212 in Figure 12. The network NW sends a first assignment message. The first assignment message indicates non-primary channel NP_CH1 for communication device CM1. The first assignment message indicates non-primary channels NP_CH2 to NP_CH4 (i.e., all available channels) or non-primary channels NP_CH2 to NP_CH4 (i.e., additional available channels) (combination) for communication device CM4. The first assignment message may optionally / further indicate primary channels P_CH for communication devices CM2 to CM3. Thus, communication device CM1 continues to apply non-primary channel NP_CH1 (e.g., block 2406_1), which corresponds to step 1408 in Figure 14. Communication devices CM2 to CM3 switch to primary channels P_CH (e.g., blocks 2406_2 and 2406_3), which corresponds to step 1404 in Figure 14. Communication device CM4 switches to the non-primary channels NP_CH2~NP_CH4 (combination) (e.g., block 2406_4), which corresponds to step 1410 in Figure 14. As communication devices CM2~CM3 switch to the primary channel P_CH, communication devices CM2~CM3 and CM5 apply the primary channel P_CH (e.g., blocks 2406_2, 2406_3, and 2406_5) via contention-based channel access (or in sequence).

[0164] Blocks 2408_1 in non-primary channel NP_CH1, 2408_2 in non-primary channel NP_CH2, 2408_3 in non-primary channel NP_CH3, and 2408_4 in non-primary channel NP_CH4 correspond to step 1206 in Figure 12. Communication devices CM1 to CM4 transmit their next individual instructions to the network NW.

[0165] Block 2410 of the primary channel P_CH and non-primary channels NP_CH1~NP_CH4 corresponds to step 1212 in Figure 12. The network NW sends the following first assignment message. The following first assignment message indicates the primary channel P_CH for communication devices CM1 and CM3. The following first assignment message indicates a combination of non-primary channels NP_CH3~NP_CH4 (i.e., all available channels) or non-primary channels NP_CH3~NP_CH4 (i.e., additional available channels) for communication device CM4. The following first assignment message may optionally / further indicate the non-primary channel NP_CH2 for communication device CM2. Thus, communication device CM1 switches to the primary channel P_CH (e.g., block 2412_1), which corresponds to step 1402 in Figure 14. Communication device CM2 switches to the non-primary channel 2 (e.g., block 2412_2), which corresponds to step 1410 in Figure 14. Communication device CM3 continues to apply the primary channel P_CH, which corresponds to step 1408 in Figure 14. Communication device CM4 switches to the non-primary channels NP_CH3~NP_CH4 (combination) (e.g., block 2412_4), which corresponds to step 1410 in Figure 14. In other words, the channels (resources in them) previously allocated to communication device CM4 are reallocated / released. Because communication device CM1 switches to the primary channel P_CH and communication device CM2 switches from the primary channel P_CH, communication devices CM1, CM3, and CM5 apply the primary channels P_CH (e.g., resources 2412_1, 2412_3, and 2412_5) by contention-based channel access (or in sequence).

[0166] Please refer to Figure 25 in combination with Figures 12 and 14. Figure 25 is a schematic diagram of primary CH P_CH and non-primary CH NP_CH1~NP_CH4 according to one embodiment of the present disclosure. Figure 12 shows an example of one communication device, and Figure 25 shows an example of multiple communication devices CM1~CM5. Communication devices CM1~CM4 operate in a specific mode, and communication device CM5 disables operation in a specific mode. Furthermore, each of communication devices CM1~CM4 may be communication device CM in Figure 12.

[0167] In Figure 25, blocks 2502_1 to 2502_4, 2504, 2506_1 to 2506_5 and 2508_1 to 2508_4 can refer to blocks 2402_1 to 2402_4, 2404, 2406_1 to 2406_5 and 2408_1 to 2408_4 in Figure 24, which are not described herein.

[0168] Block 2510 of the primary channel P_CH and non-primary channels NP_CH1 to NP_CH4 corresponds to step 1212 in Figure 12. The network NW sends the following first assignment message. The next first assignment message indicates the non-primary channel NP_CH1 for communication device CM1. The next first assignment message indicates the primary channel P_CH for communication devices CM3 to CM4. The next first assignment message may optionally / further indicate the non-primary channel NP_CH2 for communication device CM2. Thus, communication device CM1 continues to apply the non-primary channel NP_CH1 (e.g., block 2512_1), which corresponds to step 1408 in Figure 14. Communication device CM2 switches to the non-primary channel NP_CH2 (e.g., block 2512_2), which corresponds to step 1410 in Figure 14. Communication device CM3 continues to apply the primary channel P_CH. Communication device CM4 switches to primary CH P_CH (e.g., block 2512_4), which corresponds to step 1404 in Figure 14. Because communication device CM2 switches from primary CH P_CH and communication device CM4 switches to primary CH P_CH, communication devices CM3 to CM5 apply primary CH P_CH (e.g., blocks 2512_3 to 2512_5) by contention-based channel access (or in sequence).

[0169] Please refer to Figure 26 in combination with Figures 12 and 14. Figure 26 is a schematic diagram of primary CH P_CH and non-primary CH NP_CH1~NP_CH4 according to one embodiment of the present disclosure.

Communication devices CM1~CM4 operate in a specific mode, and communication device CM5 disables operation in a specific mode. Furthermore, each of communication devices CM1~CM4 may be communication device CM in Figure 12.

[0170] In Figure 26, blocks 2602_1 to 2602_4 can refer to blocks 2402_1 to 2402_4 in Figure 24, which are not described herein.

[0171] Block 2604 in non-primary channels NP_CH1 to NP_CH4 corresponds to step 1212 in Figure 12. The network NW sends a first assignment message. The first assignment message indicates non-primary channel NP_CH1 for communication device CM1. The first assignment message indicates non-primary channels NP_CH2 and NP_CH4 (combination) for communication device CM4. The first assignment message may optionally / further indicate primary channel P_CH for communication device CM2 and non-primary channel NP_CH3 for communication device CM3. Thus, communication device CM1 continues to apply non-primary channel NP_CH1 (e.g., block 2606_1), which corresponds to step 1408 in Figure 14. Communication device CM2 switches to primary channel P_CH (e.g., block 2606_2), which corresponds to step 1404 in Figure 14. Communication device CM3 continues to apply the non-primary channel NP_CH3 (e.g., block 2606_3), which corresponds to step 1408 in Figure 14. Communication device CM4 switches to the non-primary channels NP_CH2 and NP_CH4 (combination) (e.g., block 2606_4), which corresponds to step 1410 in Figure 14. Because communication device CM2 switches to the primary channel P_CH, communication devices CM2 and CM5 apply the primary channel P_CH (e.g., resources 2606_2 and 2606_5) by contention-based channel access (or in turn). For example, although both communication devices CM3 and CM4 show channel expansion, only communication device CM3 is allocated more channels (e.g., because communication device CM3 has a higher priority and / or the data to be transmitted has a higher priority).

[0172] Block 2608_1 in the non-primary channel NP_CH1, block 2608_2 in the primary channel P_CH, block 2608_3 in the non-primary channel NP_CH3, and block 2608_4 in the non-primary channels NP_CH2 and NP_CH4 correspond to step 1206 in Figure 12. Communication devices CM1 to CM4 transmit their next individual instructions to the network NW via the resources contained in the areas indicated by blocks 2608_1, 2608_2, 2608_3, and 2608_4, respectively.

The following first assignment message indicates the non-primary channel NP_CH4 for communication device CM4.

Thus, communication device CM1 switches to the primary channel P_CH (e.g., block 2612_1), which corresponds to step 1404 in Figure 14. Communication device CM2 continues to apply the primary channel P_CH, which corresponds to step 1408 in Figure 14. Communication device CM3 continues to apply the non-primary channel NP_CH3 (e.g., block 2612_3), which corresponds to step 1408 in Figure 14. Communication device CM4 switches to the non-primary channel NP_CH4 (e.g., block 2612_4), which corresponds to step 1410 in Figure 14. Because communication device CM1 switches to the primary channel P_CH, communication devices CM1-CM2 and CM5 apply the primary channel P_CH (e.g., blocks 2612_1-2612_2 and 2612_5) via contention-based channel access (or in sequence).

[0174] Figures 7, 9A, 9B, 9C, and 15-26 show the primary channel P_CH, and it should be noted that the non-primary channels NP_CH1-NP_CH4 have the same bandwidth, but are not limited to that in this specification. The bandwidth of the primary channel P_CH may differ from the bandwidth of the non-primary channels NP_CH1-NP_CH4. Furthermore, the bandwidths of the non-primary channels NP_CH1-NP_CH4 may be the same or different.

[0175] Figures 7, 9A, 9B, 9C, and 15-26 show that the number of non-primary CHs is 4, but it should be noted that this specification does not limit this to that number.
