Description

Technical Field

[0001] The present disclosure relates to the field of communications, and more particularly, to communication methods and communication devices in wireless communications. Background Art

[0002] IEEE (Institute of Electrical and Electronic Engineers) has established TG (Task group) IEEE802.11be to study the next-generation (IEEE802.11a / b / g / n / ac) Wi-Fi technology. The research scope includes: 320MHz bandwidth transmission, aggregation and coordination of multiple frequency bands, etc. It is expected to increase the rate and throughput by at least four times compared with the existing IEEE802.11ax standard. Its main application scenarios are video transmission, AR (Augmented Reality), VR (Virtual Reality), etc.

[0003] The aggregation and coordination of multiple frequency bands mean that devices communicate simultaneously in the frequency bands of 2.4GHz, 5.8GHz, and 6 - 7GHz. For devices to communicate simultaneously in multiple frequency bands, a new MAC (Media Access Control) mechanism needs to be defined for management. In addition, IEEE802.11be is also expected to support low-latency transmission.

[0004] In the discussion of the IEEE802.11be standard, the maximum supported bandwidth will be 320MHz (160MHz + 160MHz). In addition, it may also support 240MHz (160MHz + 80MHz) and the bandwidth supported in the IEEE802.11ax standard.

[0005] In the IEEE802.11be standard, the 4K QAM (quadrature amplitude modulation) modulation method (i.e., 4096QAM) will be additionally supported, and the number of spatial streams more than the 8 spatial streams (SS: space stream) in the IEEE802.11ax standard will be additionally supported (for example, 16 space-time streams or spatial streams). However, the existing standards cannot support such modulation methods and spatial streams.

[0006] In addition, since the IEEE 802.11be standard will support a bandwidth of 320 MHz (160 MHz + 160 MHz) and will support 16 * 16 MIMO (Multiple-Input Multiple-Output), existing standards cannot identify the physical parameters supported by the IEEE 802.11be standard. Summary of the Invention

[0026] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure pertains.

[0027] Figure 1 is an exemplary diagram showing a wireless communication scenario.

[0028] In a wireless local area network, a basic service set (BSS) can be composed of stations (STA: station). An STA can include an access point (AP: Access Point) device and one or more non-AP (non-AP) devices that communicate with the AP device. A basic service set can be connected to a distribution system DS (Distribution System) through its AP device, and then access another basic service set to form an extended service set ESS (Extended Service Set).

[0029] The AP device is a wireless switch for a wireless network and is also the core of the wireless network. The AP device can be used as a wireless base station and is mainly a bridge for connecting a wireless network and a wired network. Using such an AP device, a wired and wireless network can be integrated.

[0030] As an example, the AP device can include software applications and / or circuits to enable other types of nodes in the wireless network to communicate with the outside and inside of the wireless network through the AP. For example, the AP device can be a terminal device or a network device equipped with a Wi-Fi (Wireless Fidelity) chip.

[0031] As an example, non-AP devices can include but are not limited to: cellular phones, smart phones, wearable devices, computers, personal digital assistants (PDAs), personal communication system (PCS) devices, personal information managers (PIMs), personal navigation devices (PNDs), global positioning systems, multimedia devices, Internet of Things (IoT) devices, etc.

[0032] Although in Figure 1An AP device is shown communicating with three non-AP devices (non-AP 1, non-AP 2, non-AP 3), but this is merely exemplary and the embodiments of the present disclosure are not limited thereto. For example, the AP device and the non-AP devices can have any number and / or any type.

[0033] In existing standards (e.g., the IEEE 802.11ax standard), the physical parameters supported by a device in the IEEE 802.11ax standard can be identified by a High-Efficiency (HE) Operation Information Element. The format of the HE Operation Element can be as shown in Figure 2 200 in.

[0034] In Figure 2 the HE operation information element 200 of, the HE Operation Parameter field 201 can be used to indicate whether there is operation information about a standard prior to the IEEE 802.11ax standard. For example, the presence of Very High Throughput (VHT) operation information (VHT Operation Information Present) is indicated in the HE operation parameter field 201.

[0035] In addition, the IEEE 802.11ax standard also defines a Supported HE-MCS And NSS (NSS: Number of Spatial Streams) Set to indicate the combination of HE-MCS and spatial streams supported by an STA for receiving and transmitting. Figure 3 A diagram showing the format of the Supported HE-MCS And NSS Set is shown.

[0036] In the IEEE 802.11ax standard, information about the modulation and coding strategy can be carried through the Basic HE-MCS And NSS Set in the HE operation information element 200 shown in Figure 2 or each subfield in the Supported HE-MCS And NSS Set shown in Figure 3 . Figure 4 A schematic diagram showing the format of the information carried is shown.

[0037] In Figure 4 , each subfield Max HE-MCS For n SS (n = 1,..., 8) can be encoded in the following manner:

[0038] 0 indicates HE-MCS 0 to HE-MCS 7 for n spatial streams;

[0039] 1 indicates HE-MCS 0 to HE-MCS 9 for n spatial streams;

[0040] 2 indicates HE-MCS 0 to HE-MCS 11 for n spatial streams;

[0041] 3 indicates that n spatial streams are not supported.

[0042] In different resource units, HE-MCS 0 to HE-MCS 11 can correspond to different modulation schemes and coding rates. Figure 5 The corresponding modulation scheme and coding rate information for 26-tone (subcarrier) HE-MCS are shown.

[0043] Refer to Figures 2 to 5 It can be seen that the mechanisms of existing standards cannot meet the requirements of the IEEE802.11ax standard, such as 4096QAM, more spatial streams (e.g., 16 spatial streams), 320MHz (160MHz + 160MHz) bandwidth, etc.

[0044] Figure 6 It is a flowchart showing a communication method according to an exemplary embodiment. Figure 6 The shown communication method can be applied to any STA in a BSS, that is, any AP device or non-AP device.

[0045] Refer to Figure 6 , in step 610, a first message frame can be determined. In the embodiments of the present disclosure, there can be many ways to determine the first message frame. For example: The STA can generate the first message frame according to at least one of the following situations: network situation, load situation, hardware capabilities of the sending / receiving device, service type, relevant protocol regulations; the embodiments of the present disclosure do not make specific limitations thereto. In the embodiments of the present disclosure, the STA can also obtain the first message frame from an external device, and the embodiments of the present disclosure do not make specific limitations thereto.

[0046] The first message frame can be a management frame, data frame, or control frame capable of carrying various information and / data, and the embodiments of the present disclosure do not make specific limitations thereto.

[0047] To meet the requirements of 4096QAM, more spatial streams (e.g., 16 spatial streams), 320MHz (160MHz + 160MHz) bandwidth, and / or 16 * 16 MIMO supported by the IEEE802.11be standard, embodiments of the present disclosure redefine the content in the first message frame to meet the requirements of the IEEE802.11be standard.

[0048] In embodiments of the present disclosure, for ease of description, 4096QAM can be defined using R = 3 / 4 and R = 5 / 6 (R: coding rate), and the modulation and coding scheme (MCS) indices corresponding to 4096QAM can be 12 and 13. However, this is merely exemplary, and embodiments of the present disclosure are not limited thereto.

[0049] According to embodiments of the present disclosure, the first message frame may include information indicating physical parameters. The physical parameters may include combinations of modulation and coding schemes (MCSs) supported by N spatial streams, where N is a positive integer greater than 8. Hereinafter, for ease of description, N = 16 is taken as an example for description, that is, the first message frame according to embodiments of the present disclosure can meet the 16 spatial streams supported by the IEEE802.11be standard.

[0050] According to embodiments of the present disclosure, the modulation and coding scheme (MCS) combination may include MCSs corresponding to 4096 - QAM modulation and coding methods. As an example, the indices of MCSs corresponding to 4096 - QAM modulation and coding methods can be 12 and 13.

[0051] According to embodiments of the present disclosure, the modulation and coding scheme (MCS) combination includes MCSs corresponding to QPSK, 16 - QAM, 64 - QAM, 256 - QAM, and / or 1024 - QAM modulation and coding methods. As examples, the MCSs corresponding to QPSK, 16 - QAM, 64 - QAM, 256 - QAM, and / or 1024 - QAM modulation and coding methods can be 0 - 11.

[0052] It will be understood that the indices 0 to 13 in the above embodiments are merely exemplary, and the present disclosure is not limited thereto, and other index values applicable to various modulation and coding methods are also feasible.

[0053] When describing embodiments of the present disclosure, the modulation and coding scheme (MCS) can be referred to as an extreme high - throughput (EHT) - MCS, that is, EHT - MCS. Referring to the above description of index values, the modulation and coding scheme (MCS) combination may include at least one of EHT - MCS 0 to EHT - MCS 13.

[0054] Various information indicating physical parameters included in the first message frame will be described in detail below.

[0055] According to an embodiment of the present disclosure, the first message frame may include an Extremely High Throughput (EHT) Operation element to identify the physical parameters of the STA. In an example of the present disclosure, the format of the EHT Operation element may be as shown in Table 1 below:

[0056] Table 1. EHT Operation element format

[0057]

[0058] The content included in the EHT Operation Element shown in Table 1 is merely exemplary, and the embodiments of the present disclosure are not limited thereto. For example, the EHT Operation Element may further include a 6 GHz operation information field, etc.

[0059] In Table 1, the element identifier, length, element ID extension, etc. may have meanings similar to those in existing standards. For the sake of brevity, unnecessary descriptions are omitted herein.

[0060] According to an embodiment of the present disclosure, the EHT Operation element shown in Table 1 may include a Basic EHT-MCS And NSS Set, as shown in Table 2 below:

[0061] Table 2. Basic EHT-MCS And NSS Set

[0062]

[0063] Referring to Table 2, in the Basic EHT-MCS And NSS Set of the EHT Operation element, multiple first sub-domains (such as "Max EHT MCS for 1SS" to "Max EHT MCS for 16SS" in Table 2) may be included to identify the maximum (Max) EHT-MCS combinations supported by n spatial streams, where n = 1,..., N (N = 16). In an embodiment of the present disclosure, each of the multiple first sub-domains may include at least three bits, and the encoded value of each sub-domain may characterize any one of the following:

[0064] A first value indicating EHT-MCS 0 to EHT-MCS 7 for n spatial streams;

[0065] The second value indicates EHT-MCS 0 to EHT-MCS 9 for n spatial streams;

[0066] The third value indicates EHT-MCS 0 to EHT-MCS 11 for n spatial streams;

[0067] The fourth value indicates EHT-MCS 0 to EHT-MCS 13 for n spatial streams;

[0068] The fifth value indicates that n spatial streams are not supported.

[0069] In one example, the first value can be 0, the second value can be 1, the third value can be 2, the fourth value can be 3, and the fifth value can be 4. However, this is only exemplary, and the present disclosure is not limited thereto. Other values are also feasible.

[0070] It can be understood that each element in the table of the present disclosure exists independently. These elements are exemplarily listed in the same table, but it does not mean that all elements in the table must exist simultaneously as shown in the table. The value of each element is independent of the values of any other elements in Table 1. Therefore, those skilled in the art can understand that the value of each element in the table of the present disclosure is an independent embodiment.

[0071] According to an embodiment of the present disclosure, physical parameters regarding more spatial streams (N = 16 spatial streams) can be identified through a newly defined extremely high throughput operation information element (specifically, the basic EHT-MCS and NSS combination field), and the identified information includes EHT-MCS 12 and EHT-MCS 13 corresponding to 4096-QAM (i.e., supporting 4096-QAM). Therefore, the requirements of the EEE802.11be standard can be met.

[0072] Optionally, the extremely high throughput operation information element shown in Table 1 may include an EHT operation parameter field (EHTOperation Parameter) for indicating the existence of operation parameters under existing standards.

[0073] In one embodiment, the EHT operation parameter field (EHT Operation Parameter) may include a first identifier (e.g., HE Operation Parameter Present) for indicating whether there is a high-efficiency (HE) operation parameter subfield. As an example, when the first identifier (HE Operation Parameter Present) is set to "1", the EHT operation information element shown in Table 1 may include the HE operation parameter subfield (i.e., the number of bytes of HE Operation Information in Table 1 is not 0); when the first identifier (HE Operation Parameter Present) is set to "0", the EHT operation information element shown in Table 1 does not include the HE operation parameter subfield (i.e., the number of bytes of HE Operation Information in Table 1 is 0).

[0074] Optionally, the EHT operation parameter field (EHT Operation Parameter) may include a second identifier (e.g., VHT Operation Parameter Present) for indicating whether there is an ultra-high throughput (VHT) operation parameter subfield. As an example, when the second identifier (VHT Operation Parameter Present) is set to "1", the EHT operation information element shown in Table 1 includes the VHT operation parameter subfield (i.e., the number of bytes of VHT Operation Information in Table 1 is not 0); when the second identifier (VHT Operation Parameter Present) is set to "0", the EHT operation information element shown in Table 1 does not include the VHT operation parameter subfield (i.e., the number of bytes of VHT Operation Information in Table 1 is 0).

[0075] According to an embodiment of the present disclosure, the first message frame may include a Supported EHT MCS And NSS Set subfield for identifying the physical parameters of the STA, and its specific format may be as shown in Table 3 below.

[0076] Table 3. Supported EHT-MCS And NSS Set

[0077]

[0078] Referring to Table 3, the physical parameters of a 320 MHz / 160 + 160 MHz bandwidth may be included in the supported EHT-MCS and NSS combination subdomain according to an embodiment of the present disclosure. That is, the supported EHT-MCS and NSS combination subdomain may include a second subdomain indicating at least one of the following:

[0079] The received EHT-MCS mapping corresponding to a 320 MHz bandwidth (Rx EHT-MCS Map 320MHz);

[0080] The transmitted EHT-MCS mapping corresponding to a 320 MHz bandwidth (Tx EHT-MCS Map 320MHz);

[0081] The received EHT-MCS mapping corresponding to a 160 + 160 MHz bandwidth (Rx EHT-MCS Map 160 + 160MHz);

[0082] The transmitted EHT-MCS mapping corresponding to a 160 + 160 MHz bandwidth (Tx EHT-MCS Map 160 + 160MHz).

[0083] In addition, referring to Table 3, the physical parameters of a bandwidth less than or equal to 80 MHz, 160 MHz, and 80 + 80 MHz may also be included in the supported EHT-MCS and NSS combination subdomain according to an embodiment of the present disclosure. That is, the supported EHT-MCS and NSS combination subdomain includes a second subdomain indicating at least one of the following:

[0084] The received EHT-MCS mapping corresponding to a bandwidth less than or equal to 80 MHz (Rx EHT-MCS Map ≤80MHz);

[0085] The transmitted EHT-MCS mapping corresponding to a bandwidth less than or equal to 80 MHz (Tx EHT-MCS Map ≤80MHz);

[0086] The received EHT-MCS mapping corresponding to a 160 MHz bandwidth (Rx EHT-MCS Map 160MHz);

[0087] The transmitted EHT-MCS mapping corresponding to a 160 MHz bandwidth (Tx EHT-MCS Map 160MHz);

[0088] The received EHT-MCS mapping corresponding to an 80 + 80 MHz bandwidth (Rx EHT-MCS Map 80 + 80MHz);

[0089] Transmit EHT-MCS Map corresponding to a bandwidth of 80+80MHz (Tx EHT-MCS Map 80+80MHz).

[0090] As an example, each second sub-domain in the supported EHT-MCS and NSS combination sub-domain shown in Table 3 may have the format shown in Table 2 above. That is, the multiple first sub-domains shown in Table 2 may be included in each second sub-domain shown in Table 3. For the sake of brevity, the repeated description is omitted here.

[0091] In one embodiment of the present disclosure, the supported EHT-MCS and NSS combination sub-domain of Table 3 may be carried in the very high throughput operation information element shown in Table 1. In another embodiment of the present disclosure, the supported EHT-MCS and NSS combination sub-domain of Table 3 may not be carried in the very high throughput operation information element shown in Table 1, but may be carried in another information element (e.g., EHT capability information element) of the first message frame, or directly carried as a separate information element in the first message frame.

[0092] It will be understood that the first message frame may carry at least one of the very high throughput operation information element of Table 1 and the supported EHT-MCS and NSS combination sub-domain of Table 3, and the content carried by the first message frame can be determined based on the hardware conditions of the STA.

[0093] It can be understood that each element in the tables of the present disclosure exists independently. These elements are exemplarily listed in the same table, but it does not mean that all elements in the table must exist simultaneously as shown in the table. The value of each element is independent of the values of any other elements in Table 1. Therefore, those skilled in the art can understand that the value taken by each element in the tables of the present disclosure is an independent embodiment.

[0094] In some embodiments, a new very high throughput operation information element (EHT Operation element) may be defined, which at least includes the following information:

[0095] To be compatible with the IEEE802.11ax standard, it includes an EHT Operation Parameter field. In this field, at least one bit is used to identify whether it includes HE (IEEE802.11ax) Operation Parameter. For example, when the HE Operation Parameter Present field is set to "1", it indicates that the EHT Operation element includes the HE Operation Parameter field; when set to "0", it does not include.

[0096] Optionally, a single bit can also be used to indicate whether the VHT (IEEE802.11ac) OperationParameter field is included, and the indication method is the same as above.

[0097] In some embodiments, the Basic MCS And NSS Set field may also be included.

[0098] Since MCS12 and MCS13 are supported in the IEEE802.11be standard and 16 STS is supported, a new definition needs to be made for this field. The specific format can be as shown in Table 2 above. As an example, each field shown in Table 2 can also be 3 bits. In some embodiments, it can be:

[0099] — 0 indicates support for EHT-MCS 0 to EHT-MCS 7 for n spatial streams (0indicates support forEHT-MCS 0-7 for n spatial streams);

[0100] — 1 indicates support for EHT-MCS 0 to EHT-MCS 9 for n spatial streams (1indicates support forEHT-MCS 0-9 for n spatial streams);

[0101] — 2 indicates support for EHT-MCS 0 to EHT-MCS 11 for n spatial streams (2indicates support forEHT-MCS 0-11 for n spatial streams);

[0102] — 3 indicates support for EHT-MCS 0 to EHT-MCS 13 for n spatial streams (3indicates support forEHT-MCS 0-13 for n spatial stream);

[0103] — 4 indicates that n spatial streams is not supported for EHT PPDUs (4 indicates that n spatial streams is notsupported for EHT PPDUs).

[0104] In some embodiments, the Supported EHT-MCS And NSS Set can be redesigned.

[0105] Since the maximum bandwidth in IEEE 802.11be is 320 MHz, this field needs to be redesigned. As an example, its format can be as shown in Table 3 above. It will be understood that the fields for 320 MHz information in Table 3 may not always appear (the physical parameters supported by the AP and non-AP are different).

[0106] Return reference Figure 6 , in step 620, the sending end and the receiving end can communicate based on the first message frame. For example, in Figure 6 when the communication method shown is applied to the case where the AP device is the sending end, the AP device can determine the first message frame in step 610 and send the determined first message frame to the non-AP device. Correspondingly, the non-AP device can receive the first message frame and thus learn the physical parameters of the AP device based on the first message frame. For example, in Figure 6 when the communication method shown is applied to the case where the non-AP device is the sending end, the non-AP device can determine the first message frame in step 610 and send the determined first message frame to the AP device. Correspondingly, the AP device can receive the first message frame and thus learn the physical parameters of the non-AP device based on the first message frame.

[0107] Refer to Figure 6 The communication method described and the first message frame described in Tables 1 to 3 can meet the requirements of the IEEE 802.11be standard, improve the utilization efficiency of the spectrum, and increase the throughput.

[0109] Refer to Figure 7 , the communication device 700 can include a processing module 710 and a sending module 720. The processing module 710 can be configured to determine the first message frame. The first message frame can include information indicating physical parameters, and the physical parameters include modulation and coding strategy (MCS) combinations supported by N spatial streams, where N is a positive integer greater than 8. In some embodiments, the value of N is 16. The sending module 720 can be configured to communicate based on the first message frame.

[0110] According to an embodiment, the modulation and coding strategy (MCS) combination includes an MCS corresponding to 4096-QAM modulation and coding method.

[0111] According to an embodiment, the indexes of the MCS corresponding to the 4096-QAM modulation and coding method are 12 and 13.

[0116] According to an embodiment, the coded value of each first sub-domain characterizes any one of the following:

[0117] A first value indicating EHT-MCS 0 to EHT-MCS 7 for n spatial streams;

[0118] A second value indicating EHT-MCS 0 to EHT-MCS 9 for n spatial streams;

[0119] A third value indicating EHT-MCS 0 to EHT-MCS 11 for n spatial streams;

[0120] A fourth value indicating EHT-MCS 0 to EHT-MCS 13 for n spatial streams;
