[0050] Figure 1 This is a schematic diagram illustrating a communication system 100 according to an embodiment of the present invention. For example, the communication system 100 can also be applied to related devices of Virtual Reality (VR) or Augmented Reality (AR). Alternatively, the communication system 100 can be applied to multiple mobile devices, such as smartphones, tablet computers, or notebook computers, but is not limited to these. Figure 1 In some embodiments, the communication system 100 includes at least a first piconet unit 110 and a second piconet unit 120. It must be understood that, although not shown in... Figure 1 However, the communication system 100 may include more picocells, and each picocell may include other components, such as a battery, a touch control panel, a speaker, a power supply module, or (and) a housing.

[0051] The first piconet unit 110 includes a first master element 120, a first slave element 130, and a second slave element 140, wherein the first master element 120 can establish a first connection mechanism CT1 with each of the first slave element 130 and the second slave element 140. In some embodiments, both the first slave element 130 and the second slave element 140 can be directly or indirectly controlled by the first master element 120. In other embodiments, the first piconet unit 110 may also include more slave elements.

[0052] The second piconet unit 150 includes a second master element 160, a third slave element 170, and a fourth slave element 180, wherein the second master element 160 can establish a second connection mechanism CT2 with each of the third slave element 170 and the fourth slave element 180. In some embodiments, both the third slave element 170 and the fourth slave element 180 can be directly or indirectly controlled by the second master element 160. In other embodiments, the second piconet unit 150 may also include more slave elements.

[0053] Furthermore, a wireless connection mechanism WT can be established between the first master element 120 and the second master element 160. It is important to note that this wireless connection mechanism WT is different from the aforementioned first connection mechanism CT1 and second connection mechanism CT2. In other words, the second piconet unit 150 can communicate with the first piconet unit 110 in a different manner to enjoy the advantages of diversity design.

[0054] In some embodiments, either the first dominant element 120 or the second dominant element 160 may be implemented by a head-mounted display (HMD), but is not limited thereto.

[0055] In some embodiments, any one of the first subordinate element 130, the second subordinate element 140, the third subordinate element 170, and the fourth subordinate element 180 may be implemented by a physiological signal sensor, a camera element, or an inertial measurement unit (IMU), but is not limited thereto.

[0056] In some embodiments, each of the first connection mechanism CT1 and the second connection mechanism CT2 belongs to a Human Body Communication (HBC) connection. That is, the aforementioned human body communication connection can serve as an internal communication mechanism for each of the first piconet unit 110 and the second piconet unit 150.

[0057] In some embodiments, the wireless connection mechanism WT is a Bluetooth connection, such as a Bluetooth Low Energy (BLE) connection. That is, the aforementioned Bluetooth connection can serve as an external communication mechanism between the first piconet unit 110 and the second piconet unit 150. For example, the aforementioned Bluetooth connection can be used for control signal transmission, and the aforementioned human body communication connection can be used for data signal transmission, but is not limited to these.

[0058] Under the design proposed in this invention, the wireless connection mechanism WT is only used between the first dominant element 120 of the first piconet unit 110 and the second dominant element 160 of the second piconet unit 150, thus effectively saving limited bandwidth resources. According to actual measurement results, even if multiple piconet units are adjacent to each other in the communication system 100, the probability of signal packet collision between them can be significantly reduced.

[0059] Figure 2 This is a schematic diagram showing a picometer cell 210 according to an embodiment of the present invention. Figure 2 and Figure 1 Similar. Figure 2 In this embodiment, the picocell 210 is applied to different parts of a human body (HB), wherein the picocell 210 includes a master element 220, a slave element 230, and another slave element 240. For example, the master element 220 may be a head-mounted display, the slave element 230 may be a hand sensor for collecting pulse information of the human body HB, and the slave element 240 may be a leg sensor for collecting movement information of the human body HB, but is not limited thereto. The slave element 230 can transmit pulse information to the master element 220 via a human body communication connection, and the slave element 240 can also transmit movement information to the master element 220 via a human body communication connection. Then, the master element 220 may selectively share the aforementioned information with another picocell (not shown) via a Bluetooth connection. Figure 2The remaining features of the picocell 210 are all the same as Figure 1 Since the communication system 100 is similar, both embodiments can achieve similar operational effects.

[0060] Please refer to this again. Figure 1 In some embodiments, the first slave element 130 may further establish a third connection mechanism CT3 with the second slave element 140, wherein the third connection mechanism CT3 is different from the wireless connection mechanism WT. For example, the third connection mechanism CT3 may also be a human body communication connection. The communication quality of the first slave element 130 and the second slave element 140 relative to the first master element 120 can be compared with each other. Figure 1 As shown, if the second slave element 140 has better communication quality than the first slave element 130 (e.g., corresponding to a higher Received Signal Strength Indication (RSSI)), then the second slave element 140 can relay a first data D1 from the first slave element 130 to the first master element 120. Conversely, if the first slave element 130 has better communication quality than the second slave element 140, then the first slave element 130 can relay the first data D1 from the second slave element 140 to the first master element 120 (not shown). That is, the first piconet unit 110 can execute a first payload trunk procedure to select an appropriate slave element for data transmission, thereby improving the transmission efficiency of the first data D1.

[0061] In other embodiments, the third slave element 170 may establish a fourth connection mechanism CT4 with the fourth slave element 180, wherein the fourth connection mechanism CT4 is different from the wireless connection mechanism WT. For example, the fourth connection mechanism CT4 may also belong to human body communication connection. The communication quality of the third slave element 170 and the fourth slave element 180 relative to the second master element 160 can be compared with each other. Figure 1 As shown, if the fourth slave element 180 has better communication quality than the third slave element 170 (e.g., corresponding to a higher received signal strength indication), then the fourth slave element 180 can forward a second data D2 from the third slave element 170 to the second master element 160. Conversely, if the third slave element 170 has better communication quality than the fourth slave element 180, then the third slave element 170 can forward the second data D2 from the fourth slave element 180 to the second master element 160. That is, the second piconet unit 150 can execute a second payload box procedure to select an appropriate slave element for data transmission, thereby improving the transmission efficiency of the second data D2.

[0062] Figure 3This is a schematic diagram showing a communication system 300 according to an embodiment of the present invention. Figure 3 and Figure 1 Similar. Figure 3 In this embodiment, the communication system 300 includes three adjacent piconet units 310, 340, and 370. Specifically, piconet unit 310 includes a master element 320 and multiple slave elements 330-1, 330-2, ..., 330-N; piconet unit 340 includes a master element 350 and multiple slave elements 360-1, 360-2, ..., 360-M; and piconet unit 370 includes a master element 380 and multiple slave elements 390-1, 390-2, ..., 390-R, where "N", "M", and "R" can each be a positive integer greater than or equal to 3. In the communication system 300, a wireless connection mechanism WT is established only between the aforementioned master elements 320, 350, and 380. Since this wireless connection mechanism WT will not be occupied by the other slave components 330-1, 330-2, ..., 330-N, 360-1, 360-2, ..., 360-M, 390-1, 390-2, ..., 390-R, the communication system 300 will be able to maintain its own high communication quality more easily. Figure 3 The remaining features of the communication system 300 are all the same as Figure 1 The communication system 100 is similar, so both embodiments can achieve similar operational effects. It should be noted that the terms "proximate" or "adjacent" in this specification may refer to the distance between the corresponding two elements being less than a predetermined distance (e.g., 20m or less), but generally do not include the case where the corresponding two elements are in direct contact with each other (i.e., the aforementioned distance is shortened to 0).

[0063] Figure 4 This is a flowchart illustrating a communication method according to an embodiment of the present invention. First, in step S410, a first piconet unit and a second piconet unit are provided, wherein the first piconet unit includes a first master element, a first slave element, and a second slave element, and the second piconet unit includes a second master element, a third slave element, and a fourth slave element. In step S420, a first connection mechanism is established between each of the first master element and each of the first and second slave elements. In step S430, a second connection mechanism is established between each of the second master element and each of the third and fourth slave elements. Finally, in step S440, a wireless connection mechanism is established between the first master element and the second master element, wherein the wireless connection mechanism is different from the first and second connection mechanisms. It must be understood that the above steps do not need to be performed sequentially, but... Figure 1-3 Each feature of the embodiments can be applied to Figure 4 In the communication methods.

[0064] This invention proposes a novel communication system and method. Compared with traditional designs, this invention has advantages such as improved overall communication quality, reduced bandwidth resources, and lower probability of signal packet collisions, making it well-suited for application in a wide variety of devices.

[0065] It is worth noting that the component parameters described above are not limiting factors of the present invention. Designers can adjust these settings according to different needs. The communication system and communication method of the present invention are not limited to these limitations. Figure 1-4 The state shown. This invention may include only...
