Description

Technical Field

[0001] The present invention 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 content such as voice, video, packet data, messaging, and broadcast. 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 an access point (AP) station (STA) that can communicate with one or more non-AP STAs or 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 IEEE 802.11. 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). A wireless device can communicate bi-directionally with a 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 a communication link from the non-AP STA to another 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 could aim for a maximum throughput of at least 100 Gbps. The next-generation Wi-Fi technology can be called 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 technology. However, the issue of what modulation and coding scheme (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.

Mode for Carrying Out the Invention

[0028] 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 for the sole purpose of explaining specific embodiments and do not limit the present disclosure.

[0029]

Table 1

[0030] 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 in 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.

[0031] It can be understood that all the tables in this solution can be regarded as a whole, or some of these tables can form one solution. Each table can be combined with each other, and these tables do not mean that all tables are required, and one or more tables can partially cover the 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.

[0032] [Table 2]

[0033] 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, and the 320 MHz BW UHR PPDU or 640 MHz BW UHR PPDU is only applicable to the 6 GHz band. The tone plan and the position of the resource unit (RU) 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's tone plan and RU. The 640 MHz UHR PPDU is composed 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's tone plan and RU allocation.

[0034] 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 microseconds (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. Each data symbol without GI is 12.8 μs.

[0035] The data field of the UHR MU PPDU carries the PSDU for each STA within one or more intended STAs, and the UHR-SIG field of the UHR MU PPDU includes the user field of each intended STA, and the user field carries the user-specific allocation information of the STA, and the user-specific allocation information of the STA includes MCS, the number of spatial streams, and the coding method, etc. The PSDU of each intended STA is processed according to its user-specific allocation information.

[0036] The data field of the UHR TB PPDU transmitted by a non-AP STA carries a single PSDU, and the trigger frame claiming the UHR TB PPDU includes the user information field of the non-AP STA, and the user information field carries the user-specific allocation information of the non-AP STA, and the user-specific allocation information of the non-AP STA includes MCS, the number of spatial streams, and the coding method, etc. The PSDU is processed according to the user-specific allocation information of the non-AP STA.

[0037] The UUHR PHY supports 16384QAM in addition to BPSK, QPSK, 16QAM, 64QAM, 256QAM, 1024QAM, 4096QAM. Thereby, the link throughput can be further improved. It can be understood that the modulation order supported by the 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, and the UHR PHY can promote more efficient link adaptation by providing MCSs with finer granularity than the 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 the UHR PHY can achieve better PER performance by providing different MCSs with the same spectral efficiency to the EHT PHY.

[0038] One or more UHR-MCSs within the UHR-MCS set are classified into one or more inherited UHR-MCSs and one or more non-inherited UHR-MCSs. Each of the one or more inherited UHR-MCSs has its respective EHT-MCS counterpart, and each of the one or more non-inherited UHR-MCSs does not have its respective EHT-MCS counterpart. Inherited UHR-MCS refers to MCSs supported by EHT PHY or other previous protocols / Wi-Fi technologies, for example, 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 MCSs not supported by EHT PHY or other previous protocols / Wi-Fi technologies (for example, 16384QAM).

[0039] Within the framework of the present 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, Embodiment 3, and Embodiment 4) 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.

[0040] Embodiment 1 as an example:

[0041] The UHR-MCS set is

[0042] 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;

[0043] UHR-MCS with a code rate of 3 / 4 using 256QAM, and UHR-MCS with a code rate of 5 / 6 using 256QAM;

[0044] UHR-MCS with a code rate of 3 / 4 using 1024QAM and UHR-MCS with a code rate of 5 / 6 using 1024QAM, and UHR-MCS with a code rate of 3 / 4 using 4096QAM and UHR-MCS with a code rate of 5 / 6 using 4096QAM; and

[0045] including 16 inherited UHR-MCSs of UHR DUP transmission dedicated for the 6 GHz band.

[0046] Selectable example 1 as another embodiment:

[0047] The UHR-MCS set is

[0048] UHR-MCS with a code rate of 2 / 3 using QPSK, UHR-MCS with a code rate of 5 / 6 using QPSK, UHR-MCS with a code rate of 2 / 3 using 16QAM, UHR-MCS with a code rate of 5 / 6 using 16QAM, and UHR-MCS with a code rate of 2 / 3 using 256QAM;

[0049] UHR-MCS with a code rate of 2 / 3 using 4096QAM;

[0050] UHR-MCS with a code rate of 2 / 3 using 16384QAM; and

[0051] It includes nine non-inherited UHR-MCSs, namely UHR-MCS with a code rate of 3 / 4 using 16384QAM and UHR-MCS with a code rate of 5 / 6 using 16384QAM.

[0052] Selectable Example 2 as another embodiment:

[0053] The UHR-MCS set includes eight 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. Considering that the spectral efficiency of the UHR-MCS with a code rate of 2 / 3 using 16384QAM is lower than that of the UHR-MCS with a code rate of 5 / 6 using 4096QAM, the UHR-MCS set may not need to include the UHR-MCS with a code rate of 2 / 3 using 16384QAM.

[0054] 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, all other UHR-MCSs are defined for users in SU transmission or MU transmission.

[0055] Example 2 as an embodiment:

[0056] The UHR-MCS set is

[0057] 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;

[0058] UHR-MCS with a code rate of 3 / 4 using 256QAM;

[0059] UHR-MCS with a code rate of 3 / 4 using 1024QAM and UHR-MCS with a code rate of 5 / 6 using 1024QAM, and UHR-MCS with a code rate of 3 / 4 using 4096QAM and UHR-MCS with a code rate of 5 / 6 using 4096QAM; and

[0060] including 15 inherited UHR-MCSs of UHR DUP transmission dedicated for the 6 GHz band.

[0061] Selectable example 1 as another embodiment:

[0062] The UHR-MCS set is

[0063] UHR-MCS with a code rate of 2 / 3 using QPSK, UHR-MCS with a code rate of 5 / 6 using QPSK, UHR-MCS with a code rate of 2 / 3 using 16QAM, UHR-MCS with a code rate of 5 / 6 using 16QAM, and UHR-MCS with a code rate of 2 / 3 using 256QAM;

[0064] UHR-MCS with a code rate of 2 / 3 using 1024QAM;

[0065] UHR-MCS with a code rate of 2 / 3 using 4096QAM;

[0066] UHR-MCS with a code rate of 2 / 3 using 16384QAM; and

[0067] It includes 10 non-inherited UHR-MCSs of UHR-MCS with a code rate of 3 / 4 using 16384QAM and UHR-MCS with a code rate of 5 / 6 using 16384QAM.

[0068] Selectable Example 2 as an example:

[0069] 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.

[0070] The UHR-MCS with a code rate of 2 / 3 using 1024QAM used in the second embodiment and the UHR-MCS with a code rate of 5 / 6 using 256QAM used 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 is more resistant to channel fading, the UHR-MCS with a code rate of 2 / 3 using 1024QAM used in the second embodiment may be more advantageous than the UHR-MCS with a code rate of 5 / 6 using 256QAM used in the first embodiment.

[0071] UHR-MCS with a code rate of 1 / 2 using BPSK-DCM and UHR-MCS dedicated to UHR DUP transmission in the 6 GHz band are supported with only 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.

The wireless communication system may be an example of a WLAN 100 (also referred to as a Wi-Fi network) configured according to each aspect of the present disclosure (e.g., a next-generation Wi-Fi network, an 8th generation (GEN8) Wi-Fi network, an ultra-high-reliability (UHR) Wi-Fi network). 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 in 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 allows a plurality of AP STAs 10 to be connected to the ESS.

[0107] In some embodiments, the non-AP STA 20 can be located at the intersection of one or more 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 network, home network, 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 these two non-AP STAs 20 are within the same coverage area 110. Examples of the direct wireless link 120 include Wi-Fi direct connection, Wi-Fi tunneled direct link setup (TDLS) link, and other group connections. The non-AP STA 20 and the AP STA 10 can communicate according to the IEEE 802.11 and the physical layer and media access control (MAC) layer WLAN wireless protocols and baseband protocols of each version, and these versions 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. The downlink can refer to the communication link from the AP STA to the non-AP STA, and the uplink can refer to the communication link from the non-AP STA to the AP STA or from the non-AP STA to the non-AP STA.

[0108] Figure 3 shows an example of a wireless communication system according to another embodiment of the present disclosure. The wireless communication system 200 is an example of a next-generation Wi-Fi system or an Ultra-High Rate (UHR) Wi-Fi system, and may include an AP STA 10-a and non-AP STAs 20-a and 20-b, as well as a coverage area 110-a, and these components may be examples of the components described with respect to Figure 3. The AP STA 10-a can transmit a DL PPDU 210 (e.g., a UHR MU PPDU) including an RU allocation table display 215 to the non-AP STA 20 on the downlink 205.

[0109] 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 can also support multiple communication systems. 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 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 can be referred to as a conventional non-AP STA. For example, the AP STA 10 can be an example of a UHR AP STA, an example of an EHT AP STA, or an example of a conventional AP STA.

[0110] In some examples, UHR communication can support higher modulation than conventional communication. For example, UHR communication can support 16K Quadrature Amplitude Modulation (QAM), while conventional communication can support 4K QAM. 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.
