Description

Technical Field

[0001] The present disclosure relates to the field of communication systems, and more specifically, to an access point (AP) station (STA), a non-AP STA (non-access point station), and a wireless communication method capable of providing good communication performance and / or high reliability.

Background Art

[0002] Communication systems such as wireless communication systems are widely introduced to provide various types of communication contents such as voice, video, packet data, messaging, broadcast, etc. These communication systems may be multi - access systems that can support communication with multiple users by sharing available system resources (e.g., time, frequency, power). A wireless network may include one or more non - AP stations (STA) or access point (AP) STAs that can communicate with mobile devices, and the wireless network may be, for example, a wireless local area network (WLAN) (e.g., a Wi - Fi (i.e., Institute of Electrical and Electronics Engineers (IEEE) 802.11) network). As an example in the Wi - Fi field, it is understood that this solution is not limited to use with protocols such as IEEE802.11. Using a WLAN, a user can wirelessly access the Internet based on radio frequency technology at home, in the office, or in a specific service area using a portable terminal (e.g., a personal digital assistant (PDA), a laptop computer, a portable multimedia player (PMP), a smartphone, etc.). The AP STA can be coupled to a network (e.g., the Internet) to enable a mobile device to communicate via the network (or communicate with other devices coupled to the AP STA). The wireless device can communicate bi - directionally with the network device. For example, in a WLAN, a non - AP STA can communicate with an associated AP STA via a downlink and an uplink. The downlink may refer to a communication link from the AP STA to the non - AP STA, and the uplink may refer to a communication link from the non - AP STA to the AP STA or from the non - AP STA to the non - AP STA.

[0003] IEEE 802.11 TGbe is developing a new IEEE 802.11 amendment that defines a physical layer (PHY) and a medium access control (MAC) layer with extremely high throughput (EHT) that can support a maximum throughput of at least 30 gigabits per second (Gbps). The IEEE 802.11 working group is also considering next-generation Wi-Fi technologies beyond IEEE 802.11be, which aim to achieve a maximum throughput of at least 100 Gbps. The next-generation Wi-Fi technology may be referred to as the eighth generation (GEN8), ultra-high reliability (UHR), or any other name. Therefore, there may be a need to develop an efficient link adaptation scheme for next-generation Wi-Fi technologies. However, the issue of what modulation and coding schemes (MCS) the next-generation Wi-Fi technology supports to facilitate efficient link adaptation remains unresolved.

[0004] Therefore, there is a need for access point (AP) stations (STAs), non-AP STAs, and wireless communication methods that can solve the problems of the prior art, improve system throughput, improve beamforming training, improve beam tracking, improve frequency diversity gain, reduce power consumption, achieve ultra-high throughput, provide good communication performance, and / or provide high reliability. SUMMARY OF THE INVENTION

[0005] The object of the present disclosure is to solve the problems of the prior art, improve system throughput, improve beamforming training, improve beam tracking, improve frequency diversity gain, reduce power consumption, achieve ultra-high throughput, provide good communication performance, and / or provide high reliability, and propose an access point (AP) station (STA), a non-AP STA, and a wireless communication method.

[0006] In a first aspect of the present disclosure, there is a wireless communication method by an AP STA, including transmitting an ultra-high reliability (UHR) capability element by the AP STA, where the UHR capability element includes a UHR physical layer (PHY) capability information field, and a supported UHR modulation and coding scheme (UHR-MCS) and spatial stream number (NSS) set field.

DETAILED DESCRIPTION OF THE INVENTION

[0033] Hereinafter, with reference to the drawings, the technical content, structural features, achieved objects and effects of the embodiments of the present disclosure will be described in detail. Specifically, the terms in the embodiments of the present disclosure are only for the purpose of explaining specific embodiments and do not limit the present disclosure.

[0034] JPEG2025521610000029.jpg205148

[0035] The modulation schemes supported by IEEE 802.11be include BPSK, QPSK, 16QAM, 64QAM, 256QAM, 1024QAM, and 4096QAM. The EHT-MCS set includes 16 EHT-MCSs. EHT-MCS0 to EHT-MCS13 and EHT-MCS15 are defined for users in SU transmission or MU transmission, and EHT-MCS14 is specially defined for EHT DUP transmission on the 6 gigahertz (GHz) LPI channel. EHT-MCS14 and EHT-MCS15 are supported by only a single spatial stream. The parameters of EHT-MCS are shown in Table 1.

[0036]

Table 1

[0037] The bandwidth of the UHR PPDU is 20 megahertz (MHz), 40MHz, 80MHz, 160MHz, 320MHz, or 640MHz. 80MHz or 160MHz is only applicable to the 5GHz band and the 6GHz band, and 320MHz BW UHR PPDU or 640MHz BW UHR PPDU is only applicable to the 6GHz band. The tone plan and the position of the resource unit (RU) of the 20MHz UHR PPDU, 40MHz UHR PPDU, 80MHz UHR PPDU, 160MHz UHR PPDU, or 320MHz UHR PPDU are the same as those of the EHT PHY's tone plan and RU. The 640MHz UHR PPDU is composed of eight 80MHz sub-blocks, and the tone plan and RU allocation of each of these sub-blocks are the same as those of the 80MHz EHT PPDU's tone plan and RU allocation.

[0038] The UHR PPDU has two formats: the UHR MU PPDU and the UHR TB PPDU. When the PPDU is not a response to a trigger frame, the UHR MU PPDU format as shown in Figure 1A is used for transmission to one or more users. The UHR MU PPDU can be transmitted by an AP STA or a non-AP STA. In the UHR MU PPDU, the L-STF, L-LTF, L-SIG, RL-SIG, U-SIG, and UHR-SIG fields are called the pre-UHR modulation fields, and the UHR-STF, UHR-LTF, data, and PE fields are called the UHR modulation fields. The UHR TB PPDU format shown in Figure 1B is used for transmission by a non-AP STA that is a response to a trigger frame from an AP STA. In the UHR TB PPDU, the L-STF, L-LTF, L-SIG, RL-SIG, and U-SIG fields are called the pre-UHR modulation fields, and the UHR-STF, UHR-LTF, data, and PE fields are called the UHR modulation fields. The duration of the UHR-STF field in the UHR TB PPDU is twice the duration of the UHR-STF field in the UHR MU PPDU. In the case of the UHR PPDU, each UHR-LTF symbol has the same GI duration as each data symbol, and the GI duration is 0.8 μs, 1.6 μs, or 3.2 μs. The UHR-LTF field includes three types: 1xUHR-LTF, 2xUHR-LTF, and 4xUHR-LTF. The duration of each 1xUHR-LTF, 2xUHR-LTF, or 4xUHR-LTF symbol without GI is 3.2 μs, 6.4 μs, or 12.8 μs. The duration of each data symbol without GI is 12.8 μs.

[0039] In addition to BPSK, QPSK, 16QAM, 64QAM, 256QAM, 1024QAM, 4096QAM, UHR PHY also supports 16384QAM. This can further improve the link throughput. It is understood that the modulation order supported by UHR PHY may be even larger than 16384 (for example, 65536). The number of UHR-MCSs in the UHR-MCS set may be larger than the number of EHT-MCSs in the EHT-MCS set. Also, UHR PHY can promote more efficient link adaptation by providing MCSs with finer granularity than EHT PHY in terms of spectral efficiency. Alternatively, the number of UHR-MCSs in the UHR-MCS set is equal to the number of EHT-MCSs in the EHT-MCS set, and UHR PHY can achieve better PER performance by providing different MCSs with the same spectral efficiency to EHT PHY.

[0040] One or more UHR-MCSs in the UHR-MCS set are classified into one or more inherited UHR-MCSs and one or more non-inherited UHR-MCSs. The one or more inherited UHR-MCSs have their respective EHT-MCS counterparts, and the one or more non-inherited UHR-MCSs do not have their respective EHT-MCS counterparts. Inherited UHR-MCSs refer to MCSs supported by EHT PHY or other previous protocols / Wi-Fi technologies, for example, BPSK-DCM with a code rate of 1 / 2, BPSK with a code rate of 1 / 2, QPSK with a code rate of 1 / 2 or 3 / 4, 16QAM with a code rate of 1 / 2 or 3 / 4, 64QAM with a code rate of 2 / 3, 3 / 4, or 5 / 6, 256QAM with a code rate of 3 / 4, 1024QAM with a code rate of 3 / 4 or 5 / 6, and 4096QAM with a code rate of 3 / 4 or 5 / 6. Non-inherited UHR-MCSs refer to MCSs not supported by EHT PHY or other previous protocols / Wi-Fi technologies (for example, 16384QAM).

[0041] Within the framework of this disclosure, many variations and combinations of multiple embodiments (for example, but not limited to, Embodiment 1 and its selectable Examples 1 and 2, Embodiment 2 and its selectable Examples 1 and 2) are possible. Within the framework of this disclosure, combinations of one or more aspects of multiple embodiments, or combinations of different embodiments, are possible.

[0042] Embodiment 1 as an example:

[0043] The UHR-MCS set includes

[0044] UHR-MCS with a code rate of 1 / 2 using BPSK-DCM, UHR-MCS with a code rate of 1 / 2 using BPSK, UHR-MCS with a code rate of 1 / 2 using QPSK, UHR-MCS with a code rate of 3 / 4 using QPSK, UHR-MCS with a code rate of 1 / 2 using 16QAM, UHR-MCS with a code rate of 3 / 4 using 16QAM, UHR-MCS with a code rate of 2 / 3 using 64QAM, UHR-MCS with a code rate of 3 / 4 using 64QAM, and UHR-MCS with a code rate of 5 / 6 using 64QAM,

[0045] UHR-MCS with a code rate of 3 / 4 using 256QAM, and UHR-MCS with a code rate of 5 / 6 using 256QAM,

[0046] UHR-MCS with a code rate of 3 / 4 using 1024QAM, UHR-MCS with a code rate of 5 / 6 using 1024QAM, and UHR-MCS with a code rate of 3 / 4 using 4096QAM, UHR-MCS with a code rate of 5 / 6 using 4096QAM, and

[0047] 16 inherited UHR-MCSs dedicated to UHR DUP transmission in the 6 GHz band.

[0048] Selectable Example 1 as Another Embodiment:

[0049] The UHR-MCS set includes

[0050] UHR-MCS using QPSK with a code rate of 2 / 3, UHR-MCS using QPSK with a code rate of 5 / 6, UHR-MCS using 16QAM with a code rate of 2 / 3, UHR-MCS using 16QAM with a code rate of 5 / 6, and UHR-MCS using 256QAM with a code rate of 2 / 3,

[0051] UHR-MCS using 4096QAM with a code rate of 2 / 3,

[0052] UHR-MCS using 16384QAM with a code rate of 2 / 3, and

[0053] UHR-MCS using 16384QAM with a code rate of 3 / 4 and UHR-MCS using 16384QAM with a code rate of 5 / 6, including 9 non-inherited UHR-MCSs.

[0054] Selectable Example 2 as Another Embodiment:

[0055] The UHR-MCS set includes 8 non-inherited UHR-MCSs, which are the same as Selectable Example 1 except for the UHR-MCS using 16384QAM with a code rate of 2 / 3. Considering that the spectral efficiency of the UHR-MCS using 16384QAM with a code rate of 2 / 3 is lower than that of the UHR-MCS using 4096QAM with a code rate of 5 / 6, the UHR-MCS set may not need to include the UHR-MCS using 16384QAM with a code rate of 2 / 3.

[0056] The UHR-MCS with a code rate of 1 / 2 using BPSK-DCM and the UHR-MCS dedicated to UHR DUP transmission in the 6 GHz band are supported by only a single spatial stream. Except for the UHR-MCS dedicated to UHR DUP transmission in the 6 GHz band, all other UHR-MCSs are defined for users in SU transmission or MU transmission.

[0057] Example 2 as an example:

[0058] The UHR-MCS set includes

[0059] The UHR-MCS with a code rate of 1 / 2 using BPSK-DCM, the UHR-MCS with a code rate of 1 / 2 using BPSK, the UHR-MCS with a code rate of 1 / 2 using QPSK, the UHR-MCS with a code rate of 3 / 4 using QPSK, the UHR-MCS with a code rate of 1 / 2 using 16QAM, the UHR-MCS with a code rate of 3 / 4 using 16QAM, the UHR-MCS with a code rate of 2 / 3 using 64QAM, the UHR-MCS with a code rate of 3 / 4 using 64QAM, and the UHR-MCS with a code rate of 5 / 6 using 64QAM,

[0060] The UHR-MCS with a code rate of 3 / 4 using 256QAM,

[0061] The UHR-MCS with a code rate of 3 / 4 using 1024QAM, the UHR-MCS with a code rate of 5 / 6 using 1024QAM, and the UHR-MCS with a code rate of 3 / 4 using 4096QAM, the UHR-MCS with a code rate of 5 / 6 using 4096QAM,

[0062] including 15 inherited UHR-MCSs of the UHR-MCS dedicated to UHR DUP transmission in the 6 GHz band.

[0063] Selectable example 1 as another example:

[0064] The UHR-MCS set includes

[0065] a UHR-MCS with a code rate of 2 / 3 using QPSK, a UHR-MCS with a code rate of 5 / 6 using QPSK, a UHR-MCS with a code rate of 2 / 3 using 16QAM, a UHR-MCS with a code rate of 5 / 6 using 16QAM, and a UHR-MCS with a code rate of 2 / 3 using 256QAM,

[0066] a UHR-MCS with a code rate of 2 / 3 using 1024QAM,

[0067] a UHR-MCS with a code rate of 2 / 3 using 4096QAM,

[0068] a UHR-MCS with a code rate of 2 / 3 using 16384QAM, and

[0069] a UHR-MCS with a code rate of 3 / 4 using 16384QAM and a UHR-MCS with a code rate of 5 / 6 using 16384QAM, including 10 non-inherited UHR-MCSs.

[0070] Selectable Example 2 as another embodiment:

[0071] The UHR-MCS set includes 9 non-inherited UHR-MCSs, which are the same as Selectable Example 1 except for the UHR-MCS with a code rate of 2 / 3 using 16384QAM.

[0072] The UHR-MCS with a code rate of 2 / 3 using 1024QAM employed in the second embodiment and the UHR-MCS with a code rate of 5 / 6 using 256QAM employed in the first embodiment have the same spectral efficiency. Considering that using a combination of a high modulation order and a low code rate may result in a higher throughput and PER performance gain because the lower code rate has higher resistance to channel fading, the UHR-MCS with a code rate of 2 / 3 using 1024QAM employed in the second embodiment may be more advantageous than the UHR-MCS with a code rate of 5 / 6 using 256QAM employed in the first embodiment.

[0073] The UHR-MCS with a code rate of 1 / 2 using BPSK-DCM and the UHR-MCS dedicated to UHR DUP transmission in the 6GHz band are supported by only a single spatial stream. Except for the UHR-MCS dedicated to UHR DUP transmission in the 6GHz band, the other UHR-MCSs are defined for users in SU transmission or MU transmission.

[0074] 16384QAM:

[0075] In 16384QAM, each constellation point is characterized by the I coordinate and Q coordinate on an odd integer grid from -127 to 127, and each constellation point encodes 14 bits. The final constellation point is represented by the following formula:

[0076] JPEG2025521610000031.jpg936

[0077] The first 7 bits determine the I value of the constellation point, the last 7 bits determine the Q value of the constellation point, and j is the imaginary part of the complex number. The encoding of I and Q is shown in Table 2, and the encoding follows gray-coding to minimize the number of bit errors per symbol. To normalize the constellation to unit energy, each constellation point needs to be scaled by a factor K MOD = 1 / sqrt(10922).

[0078] It is understood that all the tables in this solution can be regarded as a whole, or some of these tables can form one solution. Within the framework of this disclosure, many variations and combinations of all the tables within the solution are possible. Within the framework of this disclosure, combinations of one or more aspects of all the tables, or combinations of different tables, are possible.

[0079]

Table 2

[0080] UHR-MCS Index:

[0081] One or more inherited UHR-MCSs and one or more non-inherited UHR-MCSs within the UHR-MCS set are jointly indexed. To facilitate implementation, the one or more inherited UHR-MCSs are indexed before the one or more non-inherited UHR-MCSs, and each inherited UHR-MCS has the same index as its EHT-MCS counterpart. For example, the index of a UHR-MCS using QPSK with a code rate of 3 / 4 is 2, and this index is the same as the index of the EHT-MCS using QPSK with a code rate of 3 / 4. For the UHR-MCS set defined in Selectable Example 1 of the first embodiment, the parameters of the UHR-MCS are shown in Table 3A. For the UHR-MCS set defined in Selectable Example 2 of the first embodiment, UHR-MCS22 in Table 3A can be deleted.

[0082]

Table 3A

[0083] For the UHR-MCS set defined in Selectable Example 1 of the second embodiment, the parameters of the UHR-MCS are shown in Table 3B. For the UHR-MCS set defined in Selectable Example 2 of the second embodiment, UHR-MCS23 in Table 3B can be deleted.

[0084]

Table 3B

[0085] Capability Signaling:

[0086] Non-AP STAs operating only in 20 MHz are required to support inherited UHR-MCSs using BPSK-DCM, BPSK, QPSK, 16QAM, or 64QAM. However, non-AP STAs operating only in 20 MHz may optionally support non-inherited UHR-MCSs using QPSK or 16QAM. AP STAs or non-AP STAs (excluding non-AP STAs operating only in 20 MHz) are required to support inherited UHR-MCSs using BPSK-DCM, BPSK, QPSK, 16QAM, 64QAM, or 256QAM. However, AP STAs or non-AP STAs (excluding non-AP STAs operating only in 20 MHz) may optionally support non-inherited UHR-MCSs using QPSK, 16QAM, or 256QAM. If an AP STA or non-AP STA supports 1024QAM, for a second embodiment of the UHR-MCS set, the AP STA or non-AP STA is required to support an inherited UHR-MCS using 1024QAM and may optionally support a non-inherited UHR-MCS using 1024QAM. If an AP STA or non-AP STA supports 4096QAM, the AP STA or non-AP STA is required to support an inherited UHR-MCS using 4096QAM and may optionally support a non-inherited UHR-MCS using 4096QAM. If an AP STA or non-AP STA supports 16384QAM, the AP STA or non-AP STA is required to support a non-inherited UHR-MCS using 16384QAM.

[0087] A non-AP STA can send a UHR capability element in a probe request frame, an association request frame, or a reassociation request frame. An AP STA can send a UHR capability element in a beacon frame, a probe response frame, an association response frame, or a reassociation response frame. The UHR capability element includes many fields used to notify the UHR capabilities of the AP STA or non-AP STA. In FIG. 2, the UHR capability element is defined. The UHR capability element includes a UHR PHY capability information field and a supported UHR-MCS and NSS set field.

[0088] In FIG. 3, the subfields of the UHR PHY capability information field are defined. The non-inherited MCS bitmap subfield is an 8-bit bitmap indicating that one or more non-inherited UHR-MCSs are supported. For a first example of the UHR-MCS set, for example, B0 is set to 0 to indicate that a non-inherited UHR-MCS using QPSK is not supported, set to 1 to indicate that a non-inherited UHR-MCS using QPSK is supported, or vice versa. B1 is set to 0 to indicate that a non-inherited UHR-MCS using 16QAM is not supported, set to 1 to indicate that a non-inherited UHR-MCS using 16QAM is supported, or vice versa. B2 is set to 0 to indicate that a non-inherited UHR-MCS using 256QAM is not supported, set to 1 to indicate that a non-inherited UHR-MCS using 256QAM is supported, or vice versa. B3 is set to 0 to indicate that a non-inherited UHR-MCS using 4096QAM is not supported, set to 1 to indicate that a non-inherited UHR-MCS using 4096QAM is supported, or vice versa. B4 to B7 are reserved.

[0089] For the second embodiment of the UHR-MCS set, for example, B0 is set to 0 to indicate that non-inherited UHR-MCS using QPSK is not supported, or set to 1 to indicate that non-inherited UHR-MCS using QPSK is supported, and vice versa. B1 is set to 0 to indicate that non-inherited UHR-MCS using 16QAM is not supported, or set to 1 to indicate that non-inherited UHR-MCS using 16QAM is supported, and vice versa. B2 is set to 0 to indicate that non-inherited UHR-MCS using 256QAM is not supported, or set to 1 to indicate that non-inherited UHR-MCS using 256QAM is supported, and vice versa. B3 is set to 0 to indicate that non-inherited UHR-MCS using 1024QAM is not supported, or set to 1 to indicate that non-inherited UHR-MCS using 1024QAM is supported, and vice versa. B4 is set to 0 to indicate that non-inherited UHR-MCS using 4096QAM is not supported, or set to 1 to indicate that non-inherited UHR-MCS using 4096QAM is supported, and vice versa. B5 to B7 are reserved.

[0090] The supported UHR-MCS and NSS set fields indicate combinations of the number of spatial streams Nss that the UHR-MCS and STA support for reception, as well as combinations of the number of spatial streams Nss that the UHR-MCS and STA support for transmission. An example of the format of the supported UHR-MCS and NSS set fields is shown in FIG. 4.

When the operating channel width of the STA is 320 MHz or more, the UHR-MCS map (BW = 320 MHz) subfield indicates the maximum number of spatial streams for which reception of each MCS value within a UHR PPDU with BW of 320 MHz is supported, and the maximum number of spatial streams that the STA can transmit. When the operating channel width of the STA is equal to 640 MHz, the UHR-MCS map (BW = 640 MHz) subfield indicates the maximum number of spatial streams for which reception of each MCS value within a UHR PPDU with BW of 640 MHz is supported, and the maximum number of spatial streams that the STA can transmit. The UHR-MCS map (excluding STAs with BW ≤ 80 MHz and only 20 MHz), the UHR-MCS map (BW = 160 MHz), the UHR-MCS map (BW = 320 MHz), and the UHR-MCS map (BW = 640 MHz) subfields have the format examples shown in Figure 5B.

Therefore, subset 1A can select other values, and subset 1B can select 0 (selectable support).

As described herein, the terms next-generation, GEN8, and UHR are considered synonyms and may each correspond to a Wi-Fi network that supports a large number of spatial-time streams. The WLAN 100 can include an AP STA 10 and a plurality of associated non-AP STAs 20, and these non-AP STAs 20 can represent devices such as mobile stations, personal digital assistants (PDAs), other handheld devices, netbooks, notebook computers, tablet computers, laptops, display devices (e.g., televisions (TVs), computer monitors, etc.), printers, etc. The AP STA 10 and the associated non-AP STAs 20 can represent a basic service set (BSS) or an extended service set (ESS). Each non-AP STA 20 within the network can communicate with each other via the AP STA 10. The coverage area 110 of the AP STA 10 is further shown, and the coverage area 110 can represent the basic service area (BSA) of the WLAN 100. An extended network station (not shown) associated with the WLAN 100 can be connected to a wired or wireless distribution system that enables a plurality of AP STAs 10 to be connected as an ESS.

[0100] In some embodiments, the non-AP STA 20 can be located in the common portion of multiple coverage areas 110 and can be associated with multiple AP STAs 10. A set of a single AP STA 10 and the associated non-AP STA 20 can be called a BSS. An ESS is a set of connected BSSs. A distribution system (not shown) can be used to connect the AP STAs 10 within the ESS. In some cases, the coverage area 110 of the AP STA 10 can be divided into multiple sectors (also not shown). The WLAN 100 can include different types of AP STAs 10 (e.g., metropolitan area networks, home networks, etc.), and these AP STAs 10 have different overlapping coverage areas 110. Two non-AP STAs 20 can also communicate directly via a direct wireless link 125, regardless of whether they are within the same coverage area 110. Examples of direct wireless links 120 include Wi-Fi direct connections, Wi-Fi tunneled direct link setup (TDLS) links, and other group connections. The non-AP STA 20 and the AP STA 10 can communicate according to the WLAN wireless protocol and baseband protocol of the physical layer and media access control (MAC) layer of IEEE 802.11, and the versions of these include, but are not limited to, 802.11b, 802.11g, 802.11a, 802.11n, 802.11ac, 802.11ad, 802.11ah, 802.11ax, 802.11be, 802.11ay, etc. In some other implementations, a peer-to-peer connection or an ad hoc network can be implemented within the WLAN 100.

For example, the wireless communication system 200 can support UHR communication and EHT communication. In some embodiments, the non-AP STAs 20-a and 20-b can be different types of non-AP STAs. For example, the non-AP STA 20-a may be an example of an UHR non-AP STA, and the non-AP STA 20-b may be an example of an EHT non-AP STA. The non-AP STA 20-b can be referred to as a conventional non-AP STA. For example, the AP STA 10 can be an example of an UHR AP STA, an example of an EHT AP STA, or an example of a conventional AP STA.

[0103] In some examples, UHR communication can support more spatial streams than conventional systems. In a non-limiting exemplary example, UHR communication can support 16 spatial streams, while conventional communication can support 8 spatial streams. In some cases, UHR communication may occur in an unlicensed spectrum 2.4 GHz channel, 5 GHz channel, or 6 GHz channel.
