Certain words used to describe the disclosure are discussed below or elsewhere in this specification to provide additional guidance to those skilled in the art in describing the disclosure.
Fig. 1 is a schematic diagram of a communication system according to an embodiment of the present disclosure. As shown in fig. 1, in some embodiments, a communication system 10 is shown, the communication system 10 including a first signal transceiver 110, a second signal transceiver 120, and a signal transmission structure 130. In some embodiments, the second signal transceiver 120 is coupled to the signal transmission structure 130.
It should be understood that, in some embodiments, the first signal transceiver 110 and the second signal transceiver 120 are an integration of a signal transmitter (signal transmitter) and a signal receiver (signal receiver), each of which may include at least one signal transmitter and at least one signal receiver, the signal transmitter is configured to transmit radio frequency signals to the outside, and the signal receiver is configured to receive radio frequency signals from the outside.
In some embodiments, the first signal transceiver 110 may be disposed on a Head Mounted Display (HMD). The head-mounted display device can be worn on the head of a user, so that when the user moves in a physical space or rotates the head, the head-mounted display device correspondingly moves or rotates, the first signal transceiver 110 can effectively receive/transmit radio frequency signals, and the covering angle of the first signal transceiver also moves or rotates along with the first signal transceiver.
In some embodiments, the second signal transceiver 120 and the signal transmission structure 130 form a base station (base) for transmitting rf signals to the first signal transceiver 110 or receiving rf signals from the first signal transceiver 110. In some embodiments, the first signal transceiver 110, the second signal transceiver 120 and the signal transmission structure 130 enable bidirectional wireless radio frequency signal transmission between the head-mounted display device and the communication base station, so as to implement a wireless communication Virtual Reality (VR)/Augmented Reality (AR) real-world system.
Fig. 2 is a schematic diagram illustrating a communication method according to an embodiment of the present disclosure. In some embodiments, the communication method 200 is performed by the communication system 10 of fig. 1, and reference is made to the embodiment of fig. 1 for the operation of the components of the communication system 10. The detailed steps of the communication method 200 will be described in detail in the following paragraphs.
Step S210: at least one radio frequency signal is transmitted through the second signal transceiver 120.
In some embodiments, the second signal transceiver 120 in the communication system 10 can transmit at least one rf signal. In some embodiments, the at least one rf signal is an extra high frequency (rf) signal, such as a frequency band of a millimeter wave (millimeter wave) rf signal.
It should be understood that in some embodiments, the communication system 10 may be a high frequency rf communication system, the second signal transceiver 120 may transmit the at least one rf signal, and ideally, the first signal transceiver 110 may receive the at least one rf signal, thereby completing the rf signal transmission process.
However, since the high frequency rf signal is rather dependent on the direct view between the transceivers (L ine of Sight), once the transceivers are shielded by some object, the signal received by the other transceiver will be attenuated to a great extent, resulting in a signal interruption between the two transceivers.
For a better understanding, please refer to fig. 3A of the present disclosure together. Fig. 3A is a schematic diagram of a communication system according to an embodiment of the present disclosure. As shown in fig. 3A, in some embodiments, if the first signal transceiver 110 is disposed on the head-mounted display device, under some conditions, a relative position between a body of the head-mounted display device and the first signal transceiver 110 will generate a first potential signal shielding region. That is, a line path between the first signal transceiver 110 and the second signal transceiver 120 may be shielded by the body of the head-mounted display device, thereby losing the direct view.
It should be understood that, as mentioned above, the range that is shielded by the main body of the head-mounted display device and makes it difficult for the first signal transceiver 110 to receive the radio frequency signals can be referred to as the first potential signal shielding region, and if the second signal transceiver 120 is also located in the first potential signal shielding region, the first signal transceiver 110 also has difficulty in effectively receiving the at least one radio frequency signal transmitted by the second signal transceiver 120.
For a better understanding, please also refer to fig. 3B of the present disclosure. Fig. 3B is a schematic diagram of a communication system according to an embodiment of the present disclosure. As shown in fig. 3B, in some embodiments, if the first signal transceiver 110 is disposed on the head-mounted display device, under some conditions, a relative position between a head of a user corresponding to the head-mounted display device and the first signal transceiver 110 will generate a second potential signal shielding region. That is, a line path between the first signal transceiver 110 and the second signal transceiver 120 may be shielded by the head of the user, thereby losing the direct view.
It should be understood that, as mentioned above, the range shielded by the head of the user, which makes it difficult for the first signal transceiver 110 to receive the rf signals, can be referred to as the second potential signal shielding region, and if the second signal transceiver 120 is located in the second potential signal shielding region, it is also difficult for the first signal transceiver 110 to effectively receive the at least one rf signal transmitted by the second signal transceiver 120.
Step S220: a propagation path between the signal transmitting structure 130 and the first signal transceiver 110 is adjusted by the signal transmitting structure 130 to transmit the at least one rf signal to the first signal transceiver 110 via the propagation path, wherein the propagation path is not completely shielded by the potential signal shielding region, and the signal transmitting structure 130 is in direct view corresponding to the first signal transceiver 110.
In some embodiments, the second signal transceiver 120 of the communication system 10 can operate in conjunction with the signal passing structure 130 to achieve the tasks assigned to the communication base station, wherein the communication base station is mainly used to ensure that the second signal transceiver 120 and the first signal transceiver 110 have a propagation path with direct-view. It should be noted that the propagation path with direct visibility described herein refers to a straight path through which the at least one rf signal transmitted by the second signal transceiver 120 can be directly transmitted to the first signal transceiver 110 without being blocked by the first potential signal shielding region and the second potential signal shielding region.
It should be noted that the second signal transceiver 120 and the first signal transceiver 110 in the communication base station can be implemented by the following structures in the following embodiments.

In some embodiments, the baseband circuit 121 can selectively transmit the at least one baseband signal to the rf circuit 122a in the transceiver module 122 or transmit the at least one baseband signal to the rf circuit 123a in the transceiver module 123. In some embodiments, the rf circuit 122a and the rf circuit 123a are configured to convert the at least one baseband signal into the at least one rf signal, and then transmit the at least one rf signal via the antenna 122b or the antenna 123b, respectively.

In some embodiments, the transceiver module 122 and the transceiver module 123 have a distance therebetween, which enables the antenna 122b and the antenna 123b to cover different transmission angles. In some embodiments, at least one of the antenna 122b and the antenna 123b is located outside the first potential signal shielding region and the second potential signal shielding region, in which case at least one of the transceiver module 122 or the transceiver module 123 has the propagation path with the first signal transceiver 110, and the propagation path has a direct view.

In some embodiments, the transceiver module 122 and the reflective conductor 131 have a distance therebetween, which allows the antenna 122b and the reflective conductor 131 to cover different transmission angles. In some embodiments, at least one of the antenna 122b and the reflective conductor 131 is outside the first and second potential signal shielding regions, such that at least one of the transceiver module 122 or the reflective conductor 131 is directly visible to the first signal transceiver 110.

Similar to fig. 7, in the wave guiding structure 134 of fig. 8, the first portion 134a or the second portion 134b each includes a plurality of signal channels, and as the second signal transceiver 120 adjusts the beam pointing direction of the antenna 122b to be different, the at least one rf signal can be guided through some of the signal channels of the first portion 134a or the second portion 134b and emitted in a specific direction. The termination of at least one of the first portion 134a or the second portion 134b is outside the first and the second potential signal shadow regions, such that the signal path is directly visible to the first signal transceiver 110. The second signal transceiver 120 can transmit the at least one rf signal to the first portion 134a or the second portion 134b via the transceiver module 122, and the signal channel guides the at least one rf signal to the second signal transceiver 110.
It should be noted that in some embodiments, the first signal transceiver 110 can also be used to transmit at least one response signal to the second signal transceiver 120 via the propagation path. That is, in some embodiments, the first signal transceiver 110 and the second signal transceiver 120 can exchange information in both directions when there is a direct line of sight between the first signal transceiver 110 and the second signal transceiver 120.
For a preferred understanding, please refer to fig. 9A of the present disclosure together. Fig. 9A is a schematic diagram of a communication system according to an embodiment of the present disclosure. Please compare fig. 3A and fig. 9A. In the embodiment of fig. 3A, the body of the head-mounted display device generates the first potential signal shielding region for the first signal transceiver 110, and the first signal transceiver 110 and the second signal transceiver 120 lose direct visibility. In the embodiment of fig. 9A, the body of the head-mounted display device still generates the first potential signal shielding region for the first signal transceiver 110, and the first signal transceiver 110 and the second signal transceiver 120 lose direct visibility. However, by extending the signal transmitting structure 130, the second signal transceiver 120 can transmit the at least one rf signal to the first signal transceiver 110 through a guiding position 120a, and the guiding position 120a and the signal receiver 110 have direct visibility.
It should be understood that the guiding position 120a shown in fig. 9A can be implemented by the second signal transceiver 120 and the signal transmission structure 130 in fig. 4 to 8 of the present disclosure. For example, in the embodiment of fig. 4, if the antenna 122b is limited to the first potential signal shielding region, the second signal transceiver 120 can transmit the at least one rf signal through the antenna 123b, in which case the guiding position 120a can be implemented by the transceiver module 123 including the antenna 123 b. For example, in the embodiment of fig. 6, if the first portion 132a of the reflective conductor 132 is limited to the first potential signal shielding region, the second signal transceiver 120 can transmit the at least one rf signal to the second radiating point on the second portion 132b of the reflective conductor 132 to guide the at least one rf signal through the second portion 132 b. In this case, the guiding position 120a can be implemented by the second portion 132b of the reflective conductor 132.
For a better understanding, please refer to fig. 9B of the present disclosure together. Fig. 9B is a schematic diagram of a communication system according to an embodiment of the present disclosure. Please compare fig. 3B with fig. 9B. In the embodiment of fig. 3B, the second potential signal shielding region is generated on the first signal transceiver 110 by the head of the user corresponding to the head-mounted display device, and the first signal transceiver 110 and the second signal transceiver 120 lose direct-view property. In the embodiment of fig. 9B, the user's head still creates the second potential signal shielding region for the first signal transceiver 110, and the first signal transceiver 110 and the second signal transceiver 120 lose direct visibility. However, by extending the signal transmitting structure 130, the second signal transceiver 120 can transmit the at least one rf signal to the first signal transceiver 110 through the guiding position 120a, and the guiding position 120a and the first signal transceiver 110 have a direct view.
It should be understood that the guiding position 120a shown in fig. 9B can be implemented by the second signal transceiver 120 and the signal transmission structure 130 in fig. 4 to 8 of the present disclosure. Please refer to the explanation of the embodiment of fig. 9A, which is not described herein.
As described above, the present disclosure can improve the coupling between the conventional head-mounted display device and the host computer, and the communication system 10 provides a wireless communication option. When the user uses the communication system 10, the second signal transceiver 120 and the signal transmission structure 130 cooperate to operate, so that a direct-view transmission path is provided between the second signal transceiver 120 and the first signal transceiver 110, thereby effectively ensuring signal transmission between the second signal transceiver 120 and the first signal transceiver 110 and maintaining communication stability of the communication system 10.
Although the present disclosure has been described with reference to exemplary embodiments, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the disclosure, and therefore, the scope of the disclosure is to be determined by the appended claims.
