[0036] An object of the present invention is to provide a wireless communication device with a dynamic transmission bandwidth configuration mechanism and a dynamic transmission bandwidth configuration method thereof, to configure resource units for a remote wireless communication device, and when the configuration result does not meet the resource unit configuration conditions, to reduce the bandwidth for reconfiguration, thereby effectively dynamically configuring the resource units within the transmission bandwidth range.

[0037] Please refer to Figure 1 . Figure 1 A block diagram of a wireless communication device 100 with a dynamic transmission bandwidth configuration mechanism is shown in one embodiment of the present invention.

[0038] In this embodiment, the wireless communication device 100 is an access point device, and the remote wireless communication devices 150A-150D are station devices. The wireless communication device 100 is configured to dynamically configure the transmission bandwidth of the remote wireless communication devices 150A-150D according to the orthogonal frequency division multiple access (OFDMA) technology, and then communicate with the remote wireless communication devices 150A-150D in a frequency division multiplexing manner according to the configuration result.

[0039] The wireless communication device 100 includes a communication circuit 110 , a storage circuit 120 , and a processing circuit 130 .

[0040] The storage circuit 120 is any storage device that can store the computer executable instructions 125 and the device list 135. The processing circuit 130 is electrically coupled to the communication circuit 110 and the storage circuit 120, and is used to obtain and execute the computer executable instructions 125 from the storage circuit 120. The computer executable instructions 125 include, for example, but not limited to, firmware / drivers and related instructions of hardware modules such as the communication circuit 110 and the storage circuit 120, so as to access the signals or data of the communication circuit 110 and the storage circuit 120 for calculation and execute the functions of the wireless communication device 100. The device list 135 includes information of each remote wireless communication device 150A-150D connected to the wireless device 100, such as the interference information 140 and the transmission capability 145 of each remote wireless communication device 150A-150D.

[0041] First, the processing circuit 130 obtains the communication data of each remote wireless communication device 150A- 150D included in the device list 135 stored in the storage circuit 120 , such as the interference information 140 and the transmission capability 145 .

[0042] In one embodiment, the device list 135 includes information related to each remote wireless communication device 150A-150D, and the processing circuit 130 can obtain such information by communicating with the remote wireless communication devices 150A-150D through the communication circuit 110. In one embodiment, the processing circuit 130 can obtain communication data such as interference information 140 and transmission capability 145 when the communication circuit 110 communicates with the remote wireless communication devices 150A-150D, thereby establishing the device list 135. The aforementioned communication data includes device information that can be used to identify the remote wireless communication devices 150A-150D, such as but not limited to an identification number (ID) and a media access control (MAC) address. Or related information for communication between the remote wireless communication devices 150A-150D and the wireless communication device 100, such as but not limited to the aforementioned interference information 140 and transmission capability 145.

[0043] In one embodiment, the remote wireless communication devices 150A~150D can measure the communication quality of each channel between them and the wireless communication device 100 to generate interference information 140, and report it to the wireless communication device 100 in the form of, for example but not limited to, a bandwidth query report. The remote wireless communication devices 150A~150D can also report the transmission bandwidth information they can support as the transmission capability 145 to the wireless communication device 100.

[0044] Next, the processing circuit 130 sets one of the multiple configurable transmission bandwidth ranges as the transmission bandwidth range to be configured. The transmission bandwidth range to be configured includes multiple resource units. Figure 2 A schematic diagram of a configurable transmission bandwidth range of 200 to 220.

[0045] In this embodiment, the wireless communication device 100 and the remote wireless communication devices 150A-150D may perform high efficiency multi-user (HE-MU) access via a physical layer protocol data unit (PPDD) packet format.

[0046] During communication, a symbol may be composed of a subcarrier or tone. In a range of configurable transmission bandwidths of different sizes, the remote wireless communication devices 150A-150D may be configured with different sets of subcarriers or tones to achieve simultaneous data transmission. A set of tones is referred to as a resource unit. Figure 2Taking the maximum configurable transmission bandwidth range of 80 MHz as an example, the configurable transmission bandwidth range 200-220 includes resource units of different sizes, namely 80, 40 and 20 MHz. In the configurable transmission bandwidth range 220 with a bandwidth of 20 MHz, 9 resource units A with 26 tones can be used, 4 resource units B with 52 tones can be used, 2 resource units C with 106 tones can be used, and 1 resource unit D with 242 tones can be used.

[0047] In the configurable transmission bandwidth range 210 with a bandwidth of 40 MHz, in addition to the resource units included in the two configurable transmission bandwidth ranges 220 of 20 MHz, one resource unit E of 484 tones can also be used. In the configurable transmission bandwidth range 200 of 80 MHz, in addition to the resource units included in the two configurable transmission bandwidth ranges 210 of 40 MHz, one resource unit F of 996 tones can also be used.

[0048] The configurable transmission bandwidth range 200 includes four basic channels, each corresponding to a configurable transmission bandwidth range 220. The processing circuit 130 can set one of the basic channels as a primary channel. In one embodiment, the communication quality of the resource unit of the primary channel is better than the communication quality of the resource units of other channels.

[0049] In one embodiment, the processing circuit 130 first sets the maximum configurable transmission bandwidth range 200 as the transmission bandwidth range to be configured. Then, according to the interference information 140 and the transmission capability 145, the remote wireless communication devices 150A-150D are configured in the transmission bandwidth range to be configured 200. The configuration result of the available resource units must meet the preset resource unit configuration conditions.

[0050] In one embodiment, the resource unit allocation condition causes each remote wireless communication device 150A-150D to respectively allocate resource units with non-overlapping frequency bands, at least some of the remote wireless communication devices 150A-150D are allocated resource units corresponding to the main channel, and at least resource units exceeding the threshold value are allocated.

[0051] In one embodiment, when there are N basic channels in the configurable transmission bandwidth range, at least N×4×26 tones must be configured, and for a configurable transmission bandwidth range of 200 (80 MHz), N is 4. Figure 2 As shown, since one resource unit A has 26 tones, the above requirement means that in the configurable transmission bandwidth range 200, 16 resource units A must be configured, that is, resource units of about half the bandwidth must be configured.

[0052] When the configuration result does not satisfy the resource unit configuration condition, the processing circuit 130 reduces the transmission bandwidth range 200 to be configured to another configurable transmission bandwidth range, such as to the transmission bandwidth range 210 or 220 to be configured, to determine whether the configuration result generated again satisfies the resource unit configuration condition.

[0053] When the configuration result satisfies the resource unit configuration condition, the processing circuit 130 enables the remote wireless communication devices to be respectively configured in one of the resource units according to the configuration result, so as to communicate with the remote wireless communication devices 150A-150D through the communication circuit 110.

[0054] The following will take a usage scenario as an example to describe the operation of the wireless communication device 100 in detail.

[0055] Please refer to Figure 3 . Figure 3 A schematic diagram showing resource units RU11-RU14 configured in the transmission bandwidth range 200 for remote wireless communication devices 150A-150D according to an embodiment of the present invention. In this embodiment, resource units RU11-RU14 all have 242 tones and a transmission bandwidth range of 20 MHz (equivalent to Figure 2 In the resource unit D) shown, resource unit RU13 is the main channel, and resource units RU11, RU12 and RU14 are other channels.

[0056] The processing circuit 130 configures the remote wireless communication devices 150A-150D in the to-be-configured transmission bandwidth range 200 to generate a configuration result.

[0057] In one embodiment, the processing circuit 130 determines whether the resource units RU11-RU14 cause interference to the remote wireless communication devices 150A-150D according to the interference information 140. In one embodiment, the processing circuit 130 can make a determination based on the interference parameter included in the interference information 140, so as to determine that the resource units RU11-RU14 cause interference to the remote wireless communication devices 150A-150D when the interference parameter is within a preset range.

[0058] Furthermore, the processing circuit 130 will configure each of the remote wireless communication devices 150A~150D to one of the resource units RU11~RU14 that are not interfered with and distributed from low frequency to high frequency according to the transmission capability 145 and the order of the device information of the remote wireless communication device in the device list 135 (for example but not limited to the order of numbers or media access control addresses) to generate a configuration result.

[0059] In this embodiment, resource units RU11-RU14 do not cause interference to each remote wireless communication device 150A-150D, and the transmission capability 145 shows that the remote wireless communication devices 150A-150D all support a transmission bandwidth capability of 80 MHz. The processing circuit 130 can sequentially configure the remote wireless communication devices 150A-150D to one of the resource units RU11-RU14 distributed from low frequency to high frequency in the transmission bandwidth range 200 to be configured.

[0060] In such a configuration result, the remote wireless communication devices 150A-150D are all configured to the resource units RU11-RU14 whose frequency bands do not overlap, the resource unit RU13 configured to the remote wireless communication device 150C corresponds to the primary channel, and all the resource units RU11-RU14 are configured. Therefore, the configuration results of the remote wireless communication devices 150A-150D meet the resource unit configuration condition.

[0061] Furthermore, the processing circuit 130 configures the remote wireless communication devices 150A-150D to one of the resource units RU11-RU14 according to the configuration result, and communicates with the remote wireless communication devices 150A-150D through the communication circuit 110.

[0062] Please also refer to Figure 4A and Figure 4B . Figure 4A A schematic diagram showing the interference relationship between resource units RU11 ˜ RU14 and remote wireless communication devices 150A ˜ 150D according to an embodiment of the present invention. Figure 4B A schematic diagram showing resource units RU11 - RU14 allocated to remote wireless communication devices 150A - 150D in the to-be-allocated transmission bandwidth range 200 according to an embodiment of the present invention.

[0063] In this embodiment, if Figure 4A As shown, the remote wireless communication device 150A is interfered in the resource units RU11 and RU12 shown in black. The processing circuit 130 does not configure the remote wireless communication device 150A in the resource units RU11 and RU12. The remote wireless communication device 150B is interfered in the resource units RU11 and RU12 shown in black. The processing circuit 130 does not configure the remote wireless communication device 150A in the resource units RU11 and RU12.

[0064] The remote wireless communication device 150C is interfered in the resource unit RU12 shown in black. The processing circuit 130 will not allocate the remote wireless communication device 150C in the resource unit RU12. The remote wireless communication device 150D is interfered in the resource unit RU12 shown in black. The processing circuit 130 will not allocate the remote wireless communication device 150D in the resource unit RU12.

[0065] Furthermore, the processing circuit will configure each of the remote wireless communication devices 150A~150D to one of the resource units RU11~RU14 that are not interfered with and distributed from low frequency to high frequency according to the transmission capability 145 and the order of the device information of the remote wireless communication device in the device list 135 (for example but not limited to the order of numbers or media access control addresses) to generate a configuration result.

[0066] in accordance with Figure 4A As shown, the processing circuit 130 first sequentially configures the remote wireless communication device 150A to the resource unit RU13 and the remote wireless communication device 150B to the resource unit RU14. Next, since there is no resource unit located at a higher frequency band and the resource unit RU11 does not cause interference to the remote wireless communication device 150C, the processing circuit 130 configures the remote wireless communication device 150C to the resource unit RU11.

[0067] However, in such a situation, since the resource unit RU11 causes interference to the remote wireless communication device 150D, the remote wireless communication device 150D cannot be allocated to the resource unit RU11. Therefore, such an allocation result cannot meet the resource unit allocation condition.

[0068] When the allocation result does not satisfy the resource unit allocation condition, the processing circuit 130 reduces the transmission bandwidth range 200 to be configured to another configurable transmission bandwidth range. The bandwidth reduction method may be determined according to the form of the communication packet that the processing circuit 130 wants to communicate with the remote wireless communication devices 150A-150D.

[0069] In one embodiment, when the communication packet to be communicated with the remote wireless communication device 150A-150D is a response packet (such as but not limited to a block acknowledgement (BA)), the time required for processing is more urgent. The processing circuit 130 directly reduces the transmission bandwidth range to be configured to the main transmission bandwidth range corresponding to the main channel in the configurable transmission bandwidth range 200-220, that is, the configurable transmission bandwidth range 220 corresponding to the resource unit RU13.

[0070] Please refer to Figure 5 . Figure 5A schematic diagram showing resource units RU21-RU24 configured in the transmission bandwidth range 220 for remote wireless communication devices 150A-150D according to an embodiment of the present invention. The resource units RU21-RU24 each have 52 tones (equivalent to Figure 2 Resource units B) are shown.

[0071] The processing circuit 130 configures the remote wireless communication devices 150A-150D in the to-be-configured transmission bandwidth range 220 to generate a configuration result.

[0072] Since resource units RU21~RU24 are all located in the main channel and the main channel does not cause interference to each remote wireless communication device 150A~150D, the processing circuit will configure each remote wireless communication device 150A~150D to one of the resource units RU21~RU24 that are not interfered with and distributed from low frequency to high frequency according to the transmission capability 145 and the order of the device information of the remote wireless communication device in the device list 135 (for example but not limited to the order of numbers or media access control addresses) to generate a configuration result.

[0073] In such a configuration result, the remote wireless communication devices 150A-150D are all configured to resource units with non-overlapping frequency bands, the resource units RU21-RU24 configured to the remote wireless communication devices 150A-150D correspond to the primary channels, and all resource units RU21-RU24 are configured. Therefore, the configuration results of the remote wireless communication devices 150A-150D meet the resource unit configuration conditions.

[0074] Furthermore, the processing circuit 130 configures the remote wireless communication devices 150A-150D to one of the resource units RU21-RU24 according to the configuration result, and communicates with the remote wireless communication devices 150A-150D through the communication circuit 110.

[0075] In another embodiment, when the communication packet to be communicated with the remote wireless communication device 150A-150D is not a response packet but is, for example but not limited to, a data packet, the processing time required is less urgent. The processing circuit 130 reduces the transmission bandwidth range to be configured according to the size order of the configurable transmission bandwidth range.

[0076] For example, when the transmission bandwidth range to be configured is the configurable transmission bandwidth range 200, the processing circuit 130 may reduce the transmission bandwidth range to be configured to the configurable transmission bandwidth range 210, and the configurable transmission bandwidth range 210 includes, for example, but not limited to, resource units RU13 and RU14 corresponding to the primary channel. The processing circuit 130 configures the remote wireless communication devices 150A-150D in the configurable transmission bandwidth range 210, each with four resource units of 106 tones (equivalent to Figure 2 In the resource unit C) shown, a configuration result is generated, and it is determined whether the configuration result meets the resource unit configuration condition.

[0077] When the configuration result satisfies the resource unit configuration condition, the processing circuit 130 configures the remote wireless communication devices 150A-150D in these resource units according to the configuration result. When the configuration result does not satisfy the resource unit configuration condition, the processing circuit 130 further reduces the transmission bandwidth range 210 to be configured to the main transmission bandwidth range corresponding to the main channel, that is, the configurable transmission bandwidth range 220 corresponding to the resource unit RU13.

[0078] It should be noted that the above embodiment is described with the maximum configurable transmission bandwidth range of 80 MHz as an example. In other embodiments, the maximum configurable transmission bandwidth range may also be 160 MHz or other larger bandwidths. The present invention is not limited thereto.

[0079] Furthermore, the above embodiment is described by taking four remote wireless communication devices 150A-150D as an example. In other embodiments, the number of remote wireless communication devices can be any value greater than one. The present invention is not limited thereto. It should be noted that when the number of remote wireless communication devices exceeds the total number of the minimum resource units (for example, but not limited to 26 tones), the number of remote wireless communication devices that can actually be configured will also be limited by the total number of resource units.

[0080] Furthermore, the above embodiment is described by taking the four remote wireless communication devices 150A-150D all supporting 80 MHz transmission bandwidth capability as an example. In other embodiments, the remote wireless communication devices 150A-150D may support different transmission bandwidth capabilities. The present invention is not limited thereto.

[0081] Therefore, the wireless communication device with a dynamic transmission bandwidth configuration mechanism of the present invention can use a low-complexity allocation algorithm to configure resource units for a remote wireless communication device, and when the configuration result does not meet the resource unit configuration conditions, it can quickly process it by reducing the bandwidth, thereby effectively dynamically configuring the resource units within the transmission bandwidth range.

[0082] Please refer to Figure 6 . Figure 6 A flow chart of a dynamic transmission bandwidth configuration method 600 with a dynamic transmission bandwidth configuration mechanism is shown in one embodiment of the present invention.

[0083] In addition to the aforementioned apparatus, the present invention also discloses a method 600 for dynamically configuring transmission bandwidth, which is applied to, for example, but not limited to Figure 1 In the wireless communication device 100. An embodiment of the dynamic transmission bandwidth configuration method 600 is as follows Figure 6 As shown, the following steps are included.

[0084] In step S610 : the interference information 140 and the transmission capability 145 of each remote wireless communication device 150A- 150D included in the device list 135 are obtained.

[0085] In step S620 : one of the configurable transmission bandwidth ranges 200 - 220 is set as a transmission bandwidth range to be configured, and the transmission bandwidth range to be configured includes resource units.

[0086] In step S630 : according to the interference information 140 and the transmission capability 145 , the remote wireless communication devices 150A- 150D are configured in the transmission bandwidth range to be configured to generate a configuration result.

[0087] In step S640: determine whether the configuration result satisfies the resource unit configuration condition, the resource unit configuration condition includes that each remote wireless communication device 150A~150D is configured to a resource unit with non-overlapping frequency bands, at least some of the remote wireless communication devices 150A~150D are configured to resource units corresponding to the main channel, and at least resource units exceeding the threshold value are configured.

[0088] In step S650: when the configuration result does not meet the resource unit configuration condition, the transmission bandwidth range to be configured is reduced to another configurable transmission bandwidth range. The process returns to step S640 to determine whether the configuration result generated again meets the resource unit configuration condition.

[0089] In step S660 : when the configuration result satisfies the resource unit configuration condition, the remote wireless communication devices 150A-150D are respectively configured in one of the resource units according to the configuration result, and communicate with the remote wireless communication devices 150A-150D through the communication circuit 110 .

[0090] It should be noted that the above implementation is only an example. In other embodiments, those skilled in the art may make changes without departing from the concept of the present invention.

[0091] In summary, the wireless communication device with a dynamic transmission bandwidth configuration mechanism and the dynamic transmission bandwidth configuration method thereof in the present invention can use a low-complexity allocation algorithm to configure resource units for a remote wireless communication device, and when the configuration result does not meet the resource unit configuration conditions, it can be quickly processed by reducing the bandwidth, thereby effectively dynamically configuring the resource units within the transmission bandwidth range.
