Abstract
Description
[0001] 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 that 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, broadcasting, etc. 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) station (STA) that can communicate with one or more non-AP STAs 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 solution 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 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 a medium access control (MAC) layer capable of supporting a maximum throughput of at least 30 Gbps. The IEEE 802.11 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.

[0030] 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.

[0032]
[0033]
[0034] 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 EHTDUP 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.
[0035] It is understood that all the tables in the solution can be considered as a whole, or a part of the tables can constitute a solution. The tables can be combined with each other, and these tables do not mean that all the tables are required, and one or more tables can partially cover the solution. Within the framework of the present disclosure, many variations and combinations of all the tables in the solution are possible. Within the framework of the present disclosure, combinations of one or more aspects of all the tables, or combinations of different tables are possible.
[0036] Table 1:
[0037]
[0038] 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 only applicable to the 5 GHz band and the 6 GHz band; the 320 MHz BW UHR PPDU or the 640 MHz BW UHR PPDU is only applicable 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.
[0039] The UHR PPDU has two formats: 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 is 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 0.8 microseconds (μs), 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 1x UHR-LTF, 2x UHR-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.
[0040] The data field of the UHR MU PPDU carries the PSDU of each of the one or more intended STAs, and the UHR-SIG field of the UHRMU PPDU includes a user field for each intended STA, the user field carrying user-specific allocation information of the STA, the user-specific allocation information including MCS, number of spatial streams, coding scheme, etc. The PSDU of each intended STA is processed according to its user-specific allocation information.
[0041] The data field of the UHR TB PPDU sent by the non-AP STA carries a single PSDU, and the trigger frame requesting the UHR TB PPDU includes a user information field of the non-AP STA, which carries user-specific allocation information of the non-AP STA, including MCS, number of spatial streams, coding scheme, etc. The PSDU is processed according to the user-specific allocation information of the non-AP STA.
[0042] 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 order supported by UHR PHY can even be greater than 16384 (e.g., 65536). The number of UHR-MCSs in the UHR-MCS set can be greater than the number of EHT-MCSs in the EHT-MCS set, and the UHR PHY provides a finer-grained MCS in terms of spectral efficiency than the EHT PHY, which can facilitate more efficient link adaptation. Alternatively, the number of UHR-MCSs in the UHR-MCS set can 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.
[0043] 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-dual carrier modulation (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 (eg, 16384QAM) that is not supported in EHT PHY or other earlier protocols / Wi-Fi technologies.
[0044] 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, embodiment 2 and its optional examples 1 and 2, embodiment 3, and embodiment 4, 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.
[0045] Example 1 as an embodiment:
[0046] The UHR-MCS set includes 16 inherited UHR-MCS as follows:
[0047] 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.
[0048] UHR-MCS using 256QAM and a code rate of 3 / 4, and UHR-MCS using 256QAM and a code rate of 5 / 6.
[0049] UHR-MCS using 1024QAM and a code rate of 3 / 4 and UHR-MCS using 1024QAM and a code rate of 5 / 6, as well as UHR-MCS using 4096QAM and a code rate of 3 / 4 and UHR-MCS using 4096QAM and a code rate of 5 / 6.
[0050] UHR-MCS dedicated to UHR DUP transmission in the 6GHz band.
[0051] As another example, example 1:
[0052] The UHR-MCS set includes 9 non-inherited UHR-MCSs as follows:
[0053] 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.
[0054] Utilizes UHR-MCS with 4096QAM and code rate 2 / 3.
[0055] Utilizes 16384QAM and UHR-MCS with a code rate of 2 / 3.
[0056] UHR-MCS using 16384QAM and a code rate of 3 / 4; and UHR-MCS using 16384QAM and a code rate of 5 / 6.
[0057] As another example, alternative example 2:
[0058] 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.
[0059] UHR-MCS with code rate 1 / 2 using BPSK-DCM and UHR-MCS dedicated to UHR DUP transmission in the 6 GHz band are supported only for a single spatial stream. Except for the UHR-MCS dedicated to UHR DUP transmission in the 6 GHz band, other UHR-MCSs are defined for users in SU transmission or MU transmission.
[0060] Example 2 as an embodiment:
[0061] The UHR-MCS set includes 15 inherited UHR-MCS as described below:
[0062] 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.
[0063] Utilizes UHR-MCS with 256QAM and code rate 3 / 4.
[0064] UHR-MCS using 1024QAM and a code rate of 3 / 4 and UHR-MCS using 1024QAM and a code rate of 5 / 6, as well as UHR-MCS using 4096QAM and a code rate of 3 / 4 and UHR-MCS using 4096QAM and a code rate of 5 / 6.
[0065] UHR-MCS specifically designed for UHR DUP transmission in the 6 GHz band.
[0066] As another example, example 1:
[0067] The UHR-MCS set includes 10 non-inherited UHR-MCSs as follows:
[0068] 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.
[0069] Utilizes 1024QAM and UHR-MCS with a code rate of 2 / 3.
[0070] Utilizes UHR-MCS with 4096QAM and code rate 2 / 3.
[0071] Utilizes 16384QAM and UHR-MCS with a code rate of 2 / 3.
[0072] UHR-MCS using 16384QAM and a code rate of 3 / 4; and UHR-MCS using 16384QAM and a code rate of 5 / 6.
[0073] As an optional example 2 of an embodiment:
[0074] 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.
[0075] 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.
[0076] UHR-MCS with code rate 1 / 2 using BPSK-DCM and UHR-MCS dedicated to UHR DUP transmission in the 6 GHz band are supported only for a single spatial stream. Except for the UHR-MCS dedicated to UHR DUP transmission in the 6 GHz band, other UHR-MCS are defined for users in SU transmission or MU transmission.
[0077] 16384QAM:
[0078] 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:
[0079] d=(I+jQ)×K MOD
[0080] 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. Table 2 shows the encoding of both I and Q, and both I and Q encoding follow 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 factored K MOD =1 / sqrt(10922) for scaling.
[0081] It is understood that all tables in the solution can be considered as a whole, or a portion of these tables can constitute 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.

The wireless communication system may be an example of a WLAN 100 (also referred to as a Wi-Fi network) (e.g., a next generation Wi-Fi network, an eighth generation (GEN8) Wi-Fi network, an ultra-high reliability (UHR) Wi-Fi network) configured according to various aspects of the present disclosure. As described herein, the terms next generation, GEN8, and UHR may be considered synonymous and may all correspond to a Wi-Fi network that supports a large number of space-time streams. The WLAN 100 may include an AP STA 10 and a plurality of associated non-AP STAs 20, which may represent devices such as mobile stations, personal digital assistants (PDAs), other handheld devices, netbooks, notebook computers, tablet computers, laptop computers, display devices (e.g., televisions (TVs), computer monitors, etc.), printers, and the like. The AP STA 10 and the associated non-AP STAs 20 may represent a basic service set (BSS) or an extended service set (ESS). The various non-AP STAs 20 in the network may communicate with each other through the AP STA 10. Also shown is a coverage area 110 of the AP STA 10, which may represent a basic service area (BSA) of the WLAN 100. An extended network site (not shown) associated with the WLAN 100 may be connected to a wired or wireless distribution system that may allow multiple AP STAs 10 to connect to the ESS.
[0133] In some embodiments, a non-AP STA 20 may be located at the intersection of more than one coverage area 110 and may be associated with more than one AP STA 10. A single AP STA 10 and a group of associated non-AP STAs 20 may be referred to as a BSS. An ESS is a collection of connected BSSs. A distribution system (not shown) may be used to connect the AP STAs 10 in an ESS. In some cases, the coverage area 110 of an AP STA 10 may be divided into a plurality of sectors (also not shown). The WLAN 100 may include different types of AP STAs 10 (e.g., metropolitan area networks, home networks, etc.) having different and overlapping coverage areas 110. Two non-AP STAs 20 may also communicate directly via a direct wireless link 125, regardless of whether the two non-AP STAs 20 are located in the same coverage area 110. Examples of a direct wireless link 120 may include a Wi-Fi direct connection, a Wi-Fi tunneled direct link setup (TDLS) link, and other group connections. The non-AP STA 20 and the AP STA 10 may communicate according to IEEE 802.11 and various versions of WLAN radio and baseband protocols of the physical layer and the medium access control (MAC) layer, including but 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 embodiments, a peer-to-peer connection or an ad hoc network may be implemented within the WLAN 100.

[0135] In some embodiments, the wireless communication system 200 may be a next generation Wi-Fi system (e.g., a UHR system). In some embodiments, the wireless communication system 200 may also support multiple communication systems. For example, the wireless communication system 200 may support UHR communication and EHT communication. In some embodiments, the non-AP STA 20-a and the non-AP STA 20-b may be different types of non-AP STAs. For example, the non-AP STA 20-a may be an example of a 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 may be referred to as a traditional non-AP STA. For example, the AP STA 10 may be an example of a UHR AP STA, an example of an EHT AP STA, or a traditional AP STA.
[0136] In some instances, UHR communications may support higher modulation than traditional communications. For example, UHR communications may support 16K quadrature amplitude modulation (QAM), whereas traditional communications may support 4K QAM. UHR communications may support a greater number of spatial streams than traditional systems. In one non-limiting illustrative example, UHR communications may support 16 spatial streams, whereas traditional communications may support 8 spatial streams. In some cases, UHR communications may occur on a 2.4 GHz channel, a 5 GHz channel, or a 6 GHz channel in an unlicensed spectrum.
