[0034] The definition of "circuit" applies to all usage scenarios of this term in this application (including in any claims). As another example, the term "circuit" as used herein also encompasses implementations that are only hardware circuits or processors (or multiple processors), or a part of a hardware circuit or processor, or their accompanying software or firmware.

[0035] As already mentioned above, with the development of Wi-Fi 7 technology, higher data rates can be achieved. Wi-Fi 7 technology generally involves technologies such as Multi-Link Operation (MLO), multiple input multiple output (MIMO), and 4096 Quadrature Amplitude Modulation (QAM).

[0036] MLO is one of the keys to Wi-Fi 7 technology. With MLO, Wi-Fi 7 devices can connect to two frequency bands simultaneously. This enables faster aggregation. Alternatively, these two frequency bands can be used simultaneously to share redundant / unique data, thereby improving reliability with ultra-low and precise latency.

[0037] Since the gap between the high frequency band (5935 MHz) involved in the fifth-generation mobile communication standard (5G) and the low frequency band (5945 MHz) involved in the sixth-generation mobile communication standard (6G) is only 110 MHz, signal interference inevitably exists during the application of MLO.

[0038] For example, the transmit (TX) signal spurs in the receive (RX) band will be the noise of the RX channel. To ensure the good operation of the RX channel, the TX signal spurs should be suppressed by filters and antennas.

[0039] Another key to Wi-Fi 7 technology for MLO is 4096QAM. This means it requires a higher signal-to-noise ratio (SNR). On a 320 MHz wideband, the requirement for the Error Vector Magnitude (EVM) is -46 dB.

[0040] In addition, for multi-user MIMO (multi-user MIMO, MU-MIMO) of a WIFI 7 access point (e.g., up to 16 users), when 16 antennas are required, 2G, 5G low frequency (5GL), 5G high frequency (5GH), and 6G will be supported first. This system is very complex and large, and requires a large amount of space. In this case, a reasonable antenna arrangement is worthy of discussion.

[0041] Therefore, an embodiment of the present disclosure provides a network device. The network device includes a housing, at least one set of first antennas, and at least one set of second antennas. The at least one set of first antennas and the at least one set of second antennas are respectively arranged on multiple sides of the housing in a manner that is inclined at 45 degrees with respect to the longitudinal direction of the housing, and the second antenna is spaced a predetermined distance from the first antenna arranged on the same side in the longitudinal direction, so that the at least one set of first antennas and the at least one set of second antennas meet a predetermined antenna isolation degree. The network device further includes a controller configured to adjust the phase and amplitude of a channel associated with the at least one set of first antennas and / or the at least one set of second antennas based on the operating mode of the network device, so that the channel state information of multiple channels associated with the same set of first antennas and / or second antennas is correlated or uncorrelated with each other.

[0042] In this way, on the one hand, it ensures a high isolation degree between antennas supporting different communication standards, thereby enabling good MLO and MU-MIMO performance to be achieved. On the other hand, through phase modulation and amplitude modulation, the omnidirectionality of the signal can be ensured, thereby obtaining a high-quality transmitted signal.

[0043] The principles and example embodiments of the present disclosure will be described in further detail below with reference to the accompanying drawings.

[0044] Figure 1 FIG. shows a schematic diagram of an example communication environment 100 in which the example embodiments described in the present disclosure can be implemented. The communication environment 100 may be part of a communication network. In the communication environment 100, a network device 110 and a terminal device 120 are included. The terminal device 120 can communicate with the network device 110.

[0045] In some example embodiments, the network device 110 may include a wireless router configured to provide wireless network coverage to the indoor environment where the user is located. The wireless router may be a network device compliant with the 802.11 series of standards or implemented by any suitable device, such as a Wi-Fi access point (AP), and the scope of the present disclosure is not limited in this regard. The network device 110 can communicate with other network devices (e.g., base stations) to provide wireless network coverage to terminal devices within a specific range, and the scope of the present disclosure is not limited in this regard.

[0046] In some example embodiments, the link from the network device 110 to the terminal device 120 may be referred to as a downlink (DL), while the link from the terminal device 120 to the network device 110 may be referred to as an uplink (UL). In the DL, the network device 110 is a transmitting (TX) device (or transmitter), and the terminal device 120 is a receiving (RX) device (or receiver). In the UL, the terminal device 120 is a TX device (or transmitter), and the network device 110 is an RX device (or receiver).

[0047] It should be understood that Figure 1 the number of devices and their connections shown in are merely illustrative and not restrictive. The communication environment 100 may include any suitable number of devices configured to implement the example embodiments of the present disclosure. Although not shown, it should be understood that one or more other devices may be deployed in the communication environment 100.

[0048] Communication in the communication environment 100 may be implemented according to any suitable communication protocol(s). Examples of communication protocols include, but are not limited to, first-generation (1G), second-generation (2G), 2.5G, 2.75G, third-generation (3G), fourth-generation (4G), 4.5G, fifth-generation (5G), sixth-generation (6G), etc. cellular communication protocols, wireless local area network communication protocols such as Institute of Electrical and Electronics Engineers (IEEE) 802.11, and / or any other protocol known currently or to be developed in the future.

[0049] In addition, the communication may utilize any suitable wireless communication technology, including but not limited to: code division multiple access (CDMA), frequency division multiple access (FDMA), time division multiple access (TDMA), frequency division duplexing (FDD), time division duplexing (TDD), multiple-input multiple-output (MIMO), orthogonal frequency division multiplexing (OFDM), discrete Fourier transform-based spread spectrum orthogonal frequency division multiplexing (DFT-s-OFDM), and / or any other technology known currently or to be developed in the future.

[0050] Figure 2 A schematic diagram of the antenna arrangement of the network device 110 according to some example embodiments of the present disclosure is shown.

[0051] As Figure 2 shown, the network device 110 may include a housing 210. In some embodiments, the housing 210 may be implemented as a cube. In some other embodiments, the housing 210 may be implemented as a cuboid with four equal-area sides.

[0052] The network device 110 may have a set of first antennas 221, 222, 223, and 224 and a set of second antennas 231, 232, 233, and 234. The set of first antennas 221, 222, 223, and 224 and the set of second antennas 231, 232, 233, and 234 are respectively arranged on multiple sides of the housing 210 in a manner that is inclined at 45 degrees with respect to the longitudinal direction Y of the housing 210.

[0053] It should be understood that in this article, multiple sides may be understood as the inner sidewalls of the housing 210. The fact that the set of first antennas 221, 222, 223, and 224 and the set of second antennas 231, 232, 233, and 234 are respectively arranged on multiple sides of the housing 210 may be understood as that one first antenna in the set of first antennas 221, 222, 223, and 224 is respectively arranged on each of the multiple inner sidewalls of the housing 210 and that one second antenna in the set of second antennas 231, 232, 233, and 234 is respectively arranged on each of the multiple inner sidewalls of the housing 210.

[0054] In some embodiments, the set of first antennas are antennas that support the fifth-generation mobile communication standard, while the set of second antennas are antennas that support the sixth-generation mobile communication standard. In some other embodiments, the set of first antennas and / or the set of second antennas may support more than one mobile communication standard simultaneously. For example, the set of first antennas may support the fifth-generation mobile communication standard and the second-generation mobile communication standard simultaneously.

[0055] As Figure 2 shown, the first antenna 221 and the second antenna 231 arranged on the same side 211 are spaced apart by a predetermined distance D in the longitudinal direction Y of the housing 210, and this predetermined distance D enables a predetermined antenna isolation to be satisfied between the first antenna and the second antenna that support different mobile standards. For example, the antenna isolation is 30 dB. It should be understood that the first antenna and the second antenna arranged on the same other side are also spaced apart by a predetermined distance in the longitudinal direction Y of the housing 210 so that a predetermined antenna isolation is satisfied between the first antenna and the second antenna that support different mobile standards.

[0056] In addition, the inclination directions of the first antenna 221 and the second antenna 231 arranged on the same side 211 with respect to the longitudinal axis Y of the housing 210 are opposite to each other. As Figure 2 shown, the first antenna 221 is inclined towards the first direction X1 with respect to the longitudinal axis Y of the housing 210, while the second antenna 231 is inclined towards the second direction X2 with respect to the longitudinal axis Y of the housing 210. It should be understood that the inclination directions of the first antenna and the second antenna arranged on the same other side with respect to the longitudinal axis Y of the housing 210 are also opposite to each other. Thus, it can be ensured that the transmitted signal can be well received regardless of whether it is in the case of horizontal polarization or vertical polarization.

[0057] Although only a set of first antennas and a set of second antennas arranged on the housing are shown in Figure 2 , it should be understood that more than one set of first antennas and more than one set of second antennas can also be arranged on the housing. For example, two sets of first antennas can be arranged, where one set of antennas is an antenna supporting the fifth-generation mobile communication standard, and the other set of first antennas is an antenna supporting more than one mobile communication standard at the same time, such as an antenna that can support both the fifth-generation mobile communication standard and the second-generation mobile communication standard at the same time.

[0058] Figure 3 A schematic diagram showing the antenna arrangement of the network device 110 including multiple sets of first antennas according to some example embodiments of the present disclosure is shown. It should be noted that the same or similar components as those already described in conjunction with Figure 2 will not be described in detail during the description of Figure 3 .

[0059] As Figure 3 shown, the network device 110 includes a housing 210. A first set of first antennas 221, 222, 223, and 224 and a second set of first antennas 301, 302, 303, and 304 are respectively arranged on multiple sides of the housing 210. The first set of first antennas 221, 222, 223, and 224 and the second set of first antennas 301, 302, 303, and 304 are arranged adjacent to the top surface of the housing 210. A set of second antennas 231, 232, 233, and 234 are respectively arranged on multiple sides of the housing 210. The set of second antennas is arranged adjacent to the bottom surface of the housing 210.

[0060] As Figure 3 shown, the first antenna 221 and the first antenna 301 are spaced a predetermined distance in the longitudinal direction Y of the housing 210 from the second antenna 231 arranged on the same side 311. The predetermined distance is such that a predetermined antenna isolation is satisfied between the first antennas and the second antennas supporting different mobile standards. For example, the antenna isolation is 30 dB. It should be understood that the multiple first antennas and second antennas arranged on the same other side are also spaced a predetermined distance in the longitudinal direction Y of the housing 210 so that a predetermined antenna isolation is satisfied between the first antennas and the second antennas supporting different mobile standards.

[0061] By achieving a predetermined antenna isolation between the antennas supporting different wireless communication standards, can the frequency band interference between them be significantly reduced? Especially when the gap between the high-frequency band (5935 MHz) involved in 5G and the low-frequency band (5945 MHz) involved in 6G is only 110 M, such an antenna arrangement is beneficial to improving the wireless signal quality.

[0062] The inclination directions of the first antenna 221 and the first antenna 301 with respect to the longitudinal axis Y of the housing 210 are opposite to those of the second antenna 231 arranged on the same side surface 311, while the inclination directions of the first antenna 221 and the first antenna 301 with respect to the longitudinal axis Y of the housing 210 are the same. It should be understood that the inclination directions of multiple first antennas with respect to the longitudinal axis Y of the housing 210 are opposite to those of the second antennas arranged on the same other side surface, while the inclination directions of multiple first antennas arranged on the same other side surface with respect to the longitudinal axis Y of the housing 210 are the same.

[0063] In some embodiments, the mobile communication standards supported by the first group of first antennas and the second group of first antennas are different from those supported by a group of second antennas. For example, the first group of first antennas and the second group of first antennas are antennas supporting the fifth-generation mobile communication standard, while a group of second antennas are antennas supporting the sixth-generation mobile communication standard. In some other embodiments, the first group of antennas are antennas supporting the fifth-generation mobile communication standard, while the second first antennas are antennas supporting more than one mobile communication standard at the same time. For example, they can be antennas supporting both the fifth-generation mobile communication standard and the second-generation mobile communication standard at the same time.

[0064] It should be understood that the fifth-generation mobile communication standard can be divided into 5G high-frequency band (5GH) and 5G low-frequency band (5GL) according to the supported frequency band range. Although only the second-generation mobile communication standard, the fifth-generation mobile communication standard, and the sixth-generation mobile communication standard are mentioned above, it should be understood that the network device of the present disclosure can also support other mobile communication standards. The scope of the present disclosure is not limited in this regard. In addition, although in Figure 2 and Figure 3 the example of, the number of antennas in each group is 4, that is, one in each group of antennas is arranged on each side surface of the housing. It should be understood that the number of antennas in each group can also be 8 or 16, for example. The scope of the present disclosure is not limited in this regard. Although in Figure 2 and Figure 3Examples are not shown. The network device 110 may further include at least one set of third antennas, which are respectively arranged on multiple sides of the housing 210 in a manner inclined at 45 degrees with respect to the longitudinal direction Y of the housing 210, and the third antennas are spaced a predetermined distance from the first antennas and the second antennas arranged on the same side in the longitudinal direction Y of the housing 210. In some embodiments, the at least one set of third antennas may be antennas that support other communication standards different from the fifth-generation mobile communication standard and the sixth-generation mobile communication standard. In some embodiments, the above-mentioned at least one set of first antennas, at least one set of second antennas, and at least one set of third antennas are detachable. In some embodiments, the above-mentioned at least one set of first antennas, at least one set of second antennas, and at least one set of third antennas may be integrated in one track. In some embodiments, the above-mentioned at least one set of first antennas, at least one set of second antennas, and at least one set of third antennas are o-matrix antennas, that is, orthogonal omnidirectional matrix antennas. Although in Figure 2 and Figure 3 Examples are not shown. The network device 110 of the present disclosure further includes a controller configured to adjust the phase and amplitude of channels associated with at least one set of first antennas and / or at least one set of second antennas based on the operating mode of the network device 110, so that the channel state information of multiple channels associated with the same set of first antennas and / or second antennas is correlated or uncorrelated with each other. The channel state information of a subcarrier can be expressed as: H(k) = ||H(k)||e j∠H(k) (1) where H(k) represents the channel state information of k subcarriers, ||H(k)|| represents the amplitude of k subcarriers, and H(k) represents the phase of k subcarriers. Through the channel state information, the amplitude and phase of each channel can be determined. Here, the channel state information characterizes how a wireless signal propagates from a transmitter to a receiver at a specific carrier frequency.

[0065] Figure 4A and Figure 4B shows a schematic diagram of a control circuit of a network device according to some example embodiments of the present disclosure.

[0066] As Figure 4A shown, the controller 410 is used to adjust the phase and amplitude of each channel associated with Figure 2 a set of first antennas 221, 222, 223, and 224 shown. Specifically, the first antenna 221 is connected to the phase shifter 411 and the amplitude modulator 412. The first antenna 222 is connected to the phase shifter 413 and the amplitude modulator 414. The first antenna 223 is connected to the phase shifter 415 and the amplitude modulator 416. The first antenna 224 is connected to the phase shifter 417 and the amplitude modulator 418. These amplitude modulators and phase shifters are respectively connected to the controller 410. In some embodiments, a set of first antennas 221, 222, 223, and 224 are antennas that support 5GH.

[0067] As shown Figure 4B in FIG., the controller 420 is used to adjust the phase and amplitude of each channel associated with Figure 2 a set of second antennas 231, 232, 233, and 234 shown. Specifically, the second antenna 231 is connected to the phase modulator 431 and the amplitude modulator 432. The second antenna 232 is connected to the phase modulator 423 and the amplitude modulator 424. The second antenna 233 is connected to the phase modulator 425 and the amplitude modulator 426. The second antenna 234 is connected to the phase modulator 427 and the amplitude modulator 418. These amplitude modulators and phase modulators are respectively connected to the controller 420. In some embodiments, the set of second antennas 231, 232, 233, and 234 are antennas that support the 6G high frequency band (6GH).

[0068] It should be understood that although the controller 410 configured for a set of first antennas 221, 222, 223, and 224 and the controller 420 configured for a set of second antennas 231, 232, 233, and 234 are respectively shown in Figure 4A and Figure 4B , the controller 410 and the controller 420 can also be implemented as the same controller in the network device 110. The scope of the present disclosure is not limited in this regard.

[0069] The controller can adjust the amplitude and phase of multiple channels related to a set of antennas based on the working mode of the network device 110, so that the channel state information of multiple channels related to the same set of antennas is correlated or uncorrelated with each other.

[0070] In Figure 4A the example shown, for example, in the beamforming mode, the controller 410 can make the channel state information of multiple channels associated with a set of first antennas correlated with each other. For example, making the channel state information of multiple channels associated with a set of first antennas nearly the same, that is, making the respective amplitudes and phases of multiple channels associated with a set of first antennas nearly the same. Thereby, the quality of the wireless signal can be improved, and further the data throughput can be increased.

[0071] In Figure 4A the example shown, for example, in the MIMO mode, the controller 410 can make the channel state information of multiple channels associated with a set of first antennas uncorrelated with each other. In addition, in the MIMO mode, the amplitudes of multiple channels associated with a set of first antennas can be adjusted so that the radiation directions associated with them can cover as wide a range as possible (for example, making its radiation pattern a sphere). Thereby, the interference between different channels provided for multiple users can be reduced, thus improving the quality of the wireless signal.

[0072] Correspondingly, in Figure 4BIn the illustrated example, the controller 420 can also perform similar operations.

[0073] Figure 5A and Figure 5B illustrates cases where the channel state information of multiple channels associated with different antennas is correlated with each other and uncorrelated with each other. In Figure 5A , the channel state information 501 corresponding to the antenna 221 and the channel state information 502 corresponding to the antenna 222 are correlated with each other. In Figure 5B , the channel state information 511 corresponding to the antenna 221 and the channel state information 512 corresponding to the antenna 222 are uncorrelated with each other.
