Description

background Technical Field

[0002] 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, non-AP STA) and a wireless communication method, which can provide good communication performance and / or provide high reliability.

[0003] Related technologies

[0004] Communication systems such as wireless communication systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, and broadcast. These communication systems may be multiple access systems capable of supporting communication with multiple users by sharing available system resources (e.g., time, frequency, and power). A wireless network may include an access point (AP) STA that can communicate with one or more non-AP stations (STA) or mobile devices, such as a wireless local area network (WLAN) (e.g., Wi-Fi (i.e., Institute of Electrical and Electronics Engineers (IEEE) 802.11) network). It is understood that, as an example in the field of Wi-Fi, the scheme is not limited to use in such protocols as IEEE 802.11. WLAN enables users to use portable terminals (e.g., personal digital assistants (PDAs), laptops, portable multimedia players (PMPs), smart phones, etc.) to wirelessly access the Internet based on radio frequency technology in homes, offices, or specific service areas. An AP STA may be coupled to a network (e.g., the Internet) and may enable a mobile device to communicate over the network (or communicate with other devices coupled to the AP STA). A wireless device may communicate bidirectionally with a network device. For example, in a WLAN, a non-AP STA may communicate with an associated AP STA via a downlink and an uplink. A downlink may refer to a communication link from an AP STA to a non-AP STA, and an uplink may refer to a communication link from a non-AP STA to an AP STA or from a non-AP STA to a non-AP STA.

[0005] IEEE 802.11TGbe is developing a new IEEE 802.11 amendment that defines an extremely high throughput (EHT) physical layer (PHY) and medium access control (MAC) layer capable of supporting a maximum throughput of at least 30 Gbps. The IEEE802.11 working group is also exploring the next generation of Wi-Fi technology beyond IEEE 802.11be, which can target a maximum throughput of at least 100 Gbps. The next generation of Wi-Fi technology may be called the eighth generation (GEN8), ultra-high reliability (UHR), or any other name. To this end, it may be necessary to develop an efficient link adaptation scheme for the next generation of Wi-Fi technology. However, what modulation and coding scheme (MCS) the next generation of Wi-Fi technology supports to facilitate efficient link adaptation remains an open question.

[0006] Therefore, there is a need for an access point (AP) station (STA), a non-AP STA, and a wireless communication method that can solve the problems in 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.

[0035] The technical content, structural features, achieved objectives and effects of the embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. Specifically, the terms in the embodiments of the present disclosure are only for the purpose of describing specific embodiments, and are not intended to limit the present disclosure.

[0036] surface:

[0037]

[0038]

[0039] 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-MCS 0 to EHT-MCS13 and EHT-MCS15 are defined for users in SU transmission or MU transmission; EHT-MCS14 is specifically defined for EHT DUP transmission in a 6 GHz LPI channel. EHT-MCS14 and EHT-MCS15 are supported only by a single spatial stream. The parameters of the EHT-MCS are provided in Table 1.

[0040] Table 1:

[0041]

[0042]

[0043] The bandwidth of the UHR PPDU is 20 megahertz (MHz), 40 MHz, 80 MHz, 160 MHz, 320 MHz, or 640 MHz. 80 MHz or 160 MHz is applicable only to the 5 GHz band and the 6 GHz band; the 320 MHz BW UHR PPDU or the 640 MHz BW UHR PPDU is applicable only to the 6 GHz band. The tone plan and resource unit (RU) location of the 20 MHz UHR PPDU, 40 MHz UHR PPDU, 80 MHz UHR PPDU, 160 MHz UHR PPDU, or 320 MHz UHR PPDU are the same as those of the EHT PHY. The 640 MHz UHR PPDU consists of eight 80 MHz sub-blocks, and the tone plan and RU allocation of each of these sub-blocks are the same as those of the 80 MHz EHT PPDU.

[0044] There are two formats of UHR PPDU: UHR MU PPDU and UHR TB PPDU. If the PPDU is not a response to a trigger frame, Figure 1A The UHR MU PPDU format shown in is used for transmission to one or more users. The UHR MU PPDU can be sent 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 referred to as pre-UHR modulation fields, and the UHR-STF, UHR-LTF, data, and PE fields are referred to as UHR modulation fields. Figure 1BThe UHR TB PPDU format shown is used for transmission by a non-AP STA, the transmission of which 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 referred to as pre-UHR modulation fields, and the UHR-STF, UHR-LTF, data, and PE fields are referred to as 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. For the UHR PPDU, each UHR-LTF symbol has the same GI duration as each data symbol, which is 0.8μs, 1.6μs, or 3.2μs. The UHR-LTF field includes three types: 1x UHR-LTF, 2x UHR-LTF, and 4x UHR-LTF. The duration of each 1xUHR-LTF, 2x UHR-LTF or 4x UHR-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.

[0045] In addition to BPSK, QPSK, 16QAM, 64QAM, 256QAM, 1024QAM, and 4096QAM, UHR PHY also supports 16384QAM, which can further increase link throughput. It will be appreciated that the modulation orders supported by UHR PHY may even be greater than 16384 (e.g., 65536). The number of UHR-MCSs in the UHR-MCS set may be greater than the number of EHT-MCSs in the EHT-MCS set; and the UHR PHY provides a finer-grained MCS than the EHT PHY in terms of spectral efficiency, which can facilitate more efficient link adaptation. Alternatively, the number of UHR-MCSs in the UHR-MCS set may be equal to the number of EHT-MCSs in the EHT-MCS set, and the UHR PHY provides different MCSs with the same spectral efficiency to the EHT PHY, which can achieve better PER performance.

[0046] 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, while the one or more non-inherited UHR-MCSs do not have their respective EHT-MCS counterparts. The inherited UHR-MCS refers to the MCS supported in the EHT PHY or other early protocols / Wi-Fi technologies, such as: 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-MCS refers to MCS (such as 16384QAM) not supported in EHT PHY or other early protocols / Wi-Fi technologies.

[0047] Within the framework of the present disclosure, many variations and combinations of multiple embodiments (e.g., embodiment 1 and its optional examples 1 and 2, and embodiment 2 and its optional examples 1 and 2, but not limited thereto) are possible. Within the framework of the present disclosure, combinations of one or more aspects of multiple embodiments, or combinations of different embodiments are possible.

[0048] Example 1 as an embodiment:

[0049] The UHR-MCS set includes 16 inherited UHR-MCS as follows:

[0050] UHR-MCS using BPSK-DCM with a code rate of 1 / 2, UHR-MCS using BPSK with a code rate of 1 / 2, UHR-MCS using QPSK with a code rate of 1 / 2, UHR-MCS using QPSK with a code rate of 3 / 4, UHR-MCS using 16QAM with a code rate of 1 / 2, UHR-MCS using 16QAM with a code rate of 3 / 4, UHR-MCS using 64QAM with a code rate of 2 / 3, UHR-MCS using 64QAM with a code rate of 3 / 4, and UHR-MCS using 64QAM with a code rate of 5 / 6.

[0051] UHR-MCS using 256QAM and a code rate of 3 / 4, and UHR-MCS using 256QAM and a code rate of 5 / 6.

[0052] UHR-MCS using 1024QAM and a code rate of 3 / 4, UHR-MCS using 1024QAM and a code rate of 5 / 6, UHR-MCS using 4096QAM and a code rate of 3 / 4, and UHR-MCS using 4096QAM and a code rate of 5 / 6.

[0053] UHR-MCS specifically for UHR DUP transmission in the 6 GHz band.

[0054] As another example, alternative example 1:

[0055] The UHR-MCS set includes the 9 non-inherited UHR-MCSs described below:

[0056] 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.

[0057] Utilizes UHR-MCS with 4096QAM and code rate 2 / 3.

[0058] Utilizes 16384QAM and UHR-MCS with a code rate of 2 / 3.

[0059] UHR-MCS using 16384QAM and a code rate of 3 / 4; and UHR-MCS using 16384QAM and a code rate of 5 / 6.

[0060] As another example, alternative example 2:

[0061] The UHR-MCS set includes 8 non-inherited UHR-MCSs, which are the same as the optional example 1 except that the UHR-MCS using 16384QAM and the code rate is 2 / 3. Considering that the spectrum efficiency of the UHR-MCS using 16384QAM and the code rate is lower than the spectrum efficiency of the UHR-MCS using 4096QAM and the code rate is 5 / 6, it may not be necessary for the UHR-MCS set to include the UHR-MCS using 16384QAM and the code rate is 2 / 3.

[0062] UHR-MCS with code rate 1 / 2 using BPSK-DCM and UHR-MCS dedicated to UHR DUP transmission in 6 GHz band are supported only for a single spatial stream. Except for the UHR-MCS dedicated to UHR DUP transmission in 6 GHz band, other UHR-MCS are defined for users in SU or MU transmission.

[0063] Example 2 as an embodiment:

[0064] The UHR-MCS set includes 15 inherited UHR-MCS described below:

[0065] UHR-MCS using BPSK-DCM with a code rate of 1 / 2, UHR-MCS using BPSK with a code rate of 1 / 2, UHR-MCS using QPSK with a code rate of 1 / 2, UHR-MCS using QPSK with a code rate of 3 / 4, UHR-MCS using 16QAM with a code rate of 1 / 2, UHR-MCS using 16QAM with a code rate of 3 / 4, UHR-MCS using 64QAM with a code rate of 2 / 3, UHR-MCS using 64QAM with a code rate of 3 / 4, and UHR-MCS using 64QAM with a code rate of 5 / 6.

[0066] Utilizes UHR-MCS with 256QAM and code rate 3 / 4.

[0067] UHR-MCS using 1024QAM and a code rate of 3 / 4, UHR-MCS using 1024QAM and a code rate of 5 / 6, UHR-MCS using 4096QAM and a code rate of 3 / 4, and UHR-MCS using 4096QAM and a code rate of 5 / 6.

[0068] UHR-MCS specifically for UHR DUP transmission in the 6 GHz band.

[0069] As another example, alternative example 1:

[0070] The UHR-MCS set includes 10 non-inherited UHR-MCSs described below:

[0071] 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.

[0072] Utilizes 1024QAM and UHR-MCS with a code rate of 2 / 3.

[0073] Utilizes UHR-MCS with 4096QAM and code rate 2 / 3.

[0074] Utilizes 16384QAM and UHR-MCS with a code rate of 2 / 3.

[0075] UHR-MCS using 16384QAM and a code rate of 3 / 4; and UHR-MCS using 16384QAM and a code rate of 5 / 6.

[0076] As another example, alternative example 2:

[0077] The UHR-MCS includes 9 non-inherited UHR-MCSs which are the same as the optional example 1 except for the UHR-MCS using 16384QAM and a code rate of 2 / 3.

[0078] The UHR-MCS using 1024QAM and a code rate of 2 / 3 used in the second embodiment has the same spectrum efficiency as the UHR-MCS using 256QAM and a code rate of 5 / 6 used in the first embodiment. Considering that using a higher modulation order and a lower code rate combination may achieve higher throughput and PER performance gains due to the fact that the lower code rate is more resistant to channel fading, the UHR-MCS using 1024QAM and a code rate of 2 / 3 used in the second embodiment may be more advantageous than the UHR-MCS using 256QAM and a code rate of 5 / 6 used in the first embodiment.

[0079] UHR-MCS with code rate 1 / 2 using BPSK-DCM and UHR-MCS dedicated to UHR DUP transmission in 6 GHz band are supported only for a single spatial stream. Except for the UHR-MCS dedicated to UHR DUP transmission in 6 GHz band, other UHR-MCS are defined for users in SU or MU transmission.

[0080] 16384QAM:

[0081] In 16384QAM, each constellation point is characterized by an I coordinate and a Q coordinate on an odd integer grid between -127 and 127, and each constellation point encodes 14 bits. The final constellation point is given by:

[0082] d=(I+jQ)×K MOD

[0083] The first 7 bits determine the I value of the constellation point, while the second 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, which follows gray-coding to minimize the number of bit errors per symbol. In order to normalize the constellation to unit energy, each constellation point needs to be multiplied by a factor K MOD =1 / sqrt(10922) for scaling.

[0084] It is understood that all tables in the solution can be considered as a whole, or a portion of the tables can form a solution. Many variations and combinations of all tables in the solution are possible within the framework of the present disclosure. Combinations of one or more aspects of all tables or combinations of different tables are possible within the framework of the present disclosure.

[0089]

[0090] UHR-MCS Index:

[0091] One or more inherited UHR-MCSs and one or more non-inherited UHR-MCSs in a UHR-MCS set are jointly indexed. For ease of 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 and a code rate of 3 / 4 is 2, which is the same as the index of an EHT-MCS using QPSK and a code rate of 3 / 4. For the UHR-MCS set defined in optional example 1 of the first embodiment, parameters of the UHR-MCS are provided in Table 3A. For the UHR-MCS set defined in optional example 2 of the first embodiment, UHR-MCS22 in Table 3A can be removed.

[0095] For the UHR-MCS set defined in Alternative Example 1 of the second embodiment, parameters of the UHR-MCS are provided in Table 3B. For the UHR-MCS set defined in Alternative Example 2 of the second embodiment, UHR-MCS23 in Table 3B may be removed.

[0099] Capability signaling:

[0100] Only 20MHz non-AP STAs are mandatory to support the inherited UHR-MCS using BPSK-DCM, BPSK, QPSK, 16QAM, or 64QAM. However, only 20MHz non-AP STAs can optionally support non-inherited UHR-MCS using QPSK or 16QAM. AP STA or non-AP STA (except only 20MHz non-AP STAs) are mandatory to support the inherited UHR-MCS using BPSK-DCM, BPSK, QPSK, 16QAM, 64QAM, or 256QAM. However, AP STA or non-AP STA (except only 20MHz non-AP STAs) can optionally support non-inherited UHR-MCS using QPSK, 16QAM, or 256QAM. If the AP STA or non-AP STA supports 1024QAM, then for the second embodiment of the UHR-MCS set, the AP STA or non-AP STA is forced to support the inherited UHR-MCS using 1024QAM, and optionally supports the non-inherited UHR-MCS using 1024QAM. If the AP STA or non-AP STA supports 4096QAM, then the AP STA or non-AP STA is forced to support the inherited UHR-MCS using 4096QAM, and optionally supports the non-inherited UHR-MCS using 4096QAM. If the AP STA or non-AP STA supports 16384QAM, then the AP STA or non-AP STA is forced to support the non-inherited UHR-MCS using 16384QAM.

[0101] A non-AP STA may send a UHR capability element in a probe request frame, an association request frame, or a reassociation request frame. An AP STA may 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 contains many fields for informing an AP STA or a non-AP STA of its UHR capability. Figure 2 The UHR capability element is defined in . The UHR capability element includes the UHR PHY capability information field and the supported UHR-MCS and NSS set field.

[0102] exist Figure 3The subfields of the UHR PHY Capability Information field are defined in . The Non-Inherited MCS Bitmap subfield is an 8-bit bitmap and indicates support for one or more non-inherited UHR-MCSs. For the first embodiment 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, and B0 is 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, and B1 is 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, and B2 is 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 non-inherited UHR-MCS with 4096QAM is not supported, B3 is set to 1 to indicate that non-inherited UHR-MCS with 4096QAM is supported, or vice versa. B4 to B7 are reserved.

[0103] For the second embodiment 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, and B0 is 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, and B1 is 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, and B2 is 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 1024QAM is not supported, and B3 is set to 1 to indicate that a non-inherited UHR-MCS using 1024QAM is supported, or vice versa. B4 is set to 0 to indicate that non-inherited UHR-MCS with 4096QAM is not supported, and B4 is set to 1 to indicate that non-inherited UHR-MCS with 4096QAM is supported, or vice versa. B5 to B7 are reserved.

[0104] The Supported UHR-MCS and NSS Sets field indicates the combination of UHR-MCS and the number of spatial streams Nss that the STA supports receiving, and the combination of UHR-MCS and the number of spatial streams Nss that the STA supports sending. Figure 4 An example format supporting UHR-MCS and NSS set fields is shown in FIG.

[0105] For non-AP STAs with 20 MHz bandwidth only, the UHR-MCS Map (STAs with 20 MHz bandwidth only) subfield indicates the maximum number of spatial streams supported for reception and the maximum number of spatial streams that the STA can transmit for each MCS value in a UHR PPDU with a bandwidth of 20 MHz, 40 MHz, 80 MHz, 160 MHz, 320 MHz, or 640 MHz.
