Abstract
Description
Technical Field
[0001] The present disclosure relates to the field of communications, and more particularly, to a communication method and a communication device 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 scope of research 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] Aggregation and coordination of multiple frequency bands means that devices can communicate simultaneously in the 2.4GHz, 5.8GHz and 6-7GHz frequency bands. For devices to communicate simultaneously in multiple frequency bands, a new MAC (Media Access Control) mechanism needs to be defined to manage it. In addition, IEEE802.11be is also expected to support low-latency transmission.
[0004] In the discussion of the IEEE802.11be standard, the maximum bandwidth to be supported is 320MHz (160MHz+160MHz). In addition, 240MHz (160MHz+80MHz) and the bandwidth supported by the IEEE802.11ax standard may also be supported.
[0005] In the IEEE802.11be standard, 4K QAM (quadrature amplitude modulation) modulation (i.e., 4096QAM) will be introduced. However, the IEEE802.11ax standard cannot support such modulation. In addition, the IEEE802.11be standard is only applicable to single-connection transmission, while the IEEE802.11be standard needs to support multi-connection communication (simultaneously) and needs to consider the problem of multi-connection mutual interference. Therefore, the existing standards cannot meet the requirements of the IEEE802.11be standard. Summary of the invention

[0026] Figure 1 is an exemplary diagram illustrating a wireless communication scenario.
[0027] In a wireless LAN, a basic service set (BSS) can be composed of an access point (AP) and one or more stations (STA) that communicate with the AP. A basic service set can be connected to a distribution system (DS) through its AP, and then connected to another basic service set to form an extended service set (ESS).
[0028] AP is a wireless switch used in wireless networks and is also the core of wireless networks. AP devices can be used as wireless base stations, mainly as bridges to connect wireless networks and wired networks. Using this access point AP, wired and wireless networks can be integrated.
[0029] As an example, an AP may include software applications and / or circuits to enable other types of nodes in a wireless network to communicate with the outside and inside of the wireless network through the AP. For example, an AP may be a terminal device or network device equipped with a Wi-Fi (Wireless Fidelity) chip.
[0030] As an example, a station (STA) may include, but is not limited to, a cellular phone, a smart phone, a wearable device, a computer, a personal digital assistant (PDA), a personal communication system (PCS) device, a personal information manager (PIM), a personal navigation device (PND), a global positioning system, a multimedia device, an Internet of Things (IoT) device, etc.
[0031] Although in Figure 1 It is shown that one AP communicates with three stations (STA1, STA2, STA3), but this is merely exemplary and the embodiments of the present disclosure are not limited thereto. For example, the AP and the stations may be of any number and / or type.
[0032] Figure 2 is a flow chart illustrating a communication method according to an example embodiment. Figure 2 The communication method shown can be applied to a site (e.g., Figure 1 STA1, STA2, STA3 in it).
[0033] Reference Figure 2 In step 210, a first message frame may be determined. In an embodiment of the present disclosure, there may be many ways to determine the first message frame, for example, the site may generate the first message frame according to at least one of the following conditions: network conditions, load conditions, hardware capabilities of the sending / receiving device, service type, and related protocol provisions; this embodiment of the present disclosure is not specifically limited to this. In an embodiment of the present disclosure, the site may also obtain the first message frame from an external device, which is not specifically limited to this embodiment of the present disclosure.
[0034] According to an embodiment of the present disclosure, the first message frame may include an uplink multi-user power capability information element. For ease of description, hereinafter, the uplink multi-user power capability information element according to an embodiment of the present disclosure may be referred to as an extremely high throughput uplink multi-user power capability information element, abbreviated as "EHT UL MU power capability information element". In an embodiment of the present disclosure, the first message frame may be an association request frame (Association Request) or a re-association request frame (Re-Association Request), however, this is only exemplary, and the embodiments of the present disclosure are not limited thereto, and other types of frames are also feasible. The station (non-AP HE STA) may use the EHT (extreme High Throughput) UL (Uplink) MU (multi-user) power capability information element in the association request frame or the re-association request frame or reuse the existing HE UL MU power capability information element to notify the access point (HE (High Efficiency) AP) of the relative maximum transmit power at which the station can send HE TB (trigger-based) PPDU (trigger-based high efficiency PPDU). The access point (HE AP) may allocate uplink transmission resources to the station (non-AP HE STA) according to the EHT UL MU power capability information element.
[0035] According to an embodiment of the present disclosure, the EHT UL MU power capability information element may be encapsulated in the first message frame. An example of encapsulating the EHT UL MU power capability information element will be described in detail later with reference to Tables 2 to 5.
[0036] The following will first describe the EHT UL MU power capability information element according to an embodiment of the present disclosure. In an embodiment of the present disclosure, the EHT UL MU power capability information element is redesigned / set to be able to additionally support 4096QAM in the IEEE 802.11be standard.
[0037] In an embodiment of the present disclosure, for ease of description, 4096QAM can be represented by R=3 / 4 and R=5 / 6 (R: coding rate), and the modulation and coding strategy (MCS: modulation and coding scheme) index numbers corresponding to 4096QAM can be 12 and 13. However, this is only exemplary, and the embodiments of the present disclosure are not limited thereto. According to an embodiment of the present disclosure, the EHT UL MU power capability information element may include: an identification bit for indicating the relative maximum transmit power associated with various modulation modes. Such an identification bit can be used to indicate / identify the maximum power value of the site to send an uplink data frame, and each identification bit can correspond to a modulation and coding strategy. In an embodiment of the present disclosure, considering the case of the IEEE802.11be standard, the MCS according to an embodiment of the present disclosure may be referred to as an extremely high throughput (EHT) / high efficiency (HE) MCS.
[0038] According to an embodiment, the EHT UL MU power capability information element may include: a first information identifier related to the relative maximum transmit power of QPSK, 16-QAM, 64-QAM, 256-QAM and 1024-QAM modulation modes, respectively, and / or a second information identifier of the relative maximum transmit power of the 4096QAM modulation mode. Both the first information identifier and the second information identifier may be used to indicate / identify the maximum power value of the station to send an uplink data frame. It will be understood that although the EHT UL MU power capability information element is described in the present application as including the first information identifier and / or the second information identifier, the first information identifier and the second information identifier may both be set in the same field of the EHT UL MU power capability information element to identify the relative maximum transmit power.
[0039] According to an embodiment, the first information identifier may correspond to an MCS having index numbers of the first value to the second value, respectively, and the second information identifier may correspond to an MCS having an index number different from the first value to the second value. In other words, the index number of the MCS corresponding to the first information identifier may be set to the first value to the second value (for example, "EHT / HE MCS 1" to "EHT / HE MCS 11" in Table 1 below); the index number of the MCS corresponding to the second information identifier may be different from the first value to the second value (for example, "EHT / HE MCS 12" and "EHT / HE MCS 13" in Table 1 below), which will be described in detail later with reference to Table 1.
[0040] According to an embodiment, the EHT UL MU power capability information element may include an element identification extension bit (e.g., "Element ID extension" in Table 1 below). In an embodiment of the present disclosure, the element identification extension bit may be set to a specific value for indicating the EHT UL MU power capability information element.
[0041] In the case where a station STA supporting the IEEE 802.11be standard communicates with an access point AP supporting the IEEE 802.11be standard (for example, when they make an initial association connection), the EHT UL MU power capability information element according to an embodiment of the present disclosure may have a format as shown in Table 1, for example only.
[0042] Table 1. Format of the EHT UL MU Power Capability Information Element
[0043]
[0044] According to an embodiment, in Table 1, the element ID subfield may be set to 255, and the element ID extension bit may be set to a specific value (e.g., 61) to indicate / identify the EHT UL MU power capability information element according to an embodiment of the present disclosure.
[0045] Referring to Table 1, the first information identifier in the EHT UL MU power capability information element may correspond to Relative MAX transmit power EHT / HE MCS 1 (relative maximum transmit power EHT / HE MCS 1) to Relative MAX transmit power EHT / HE MCS 11 (relative maximum transmit power EHT / HE MCS 11. That is, Relative MAX transmit power EHT / HE MCS 1 to Relative MAX transmit power EHT / HE MCS 11 may correspond to QPSK, 16-QAM, 64-QAM, 256-QAM, and 1024-QAM modulation modes. That is, the EHT UL MU power capability information element according to an embodiment of the present disclosure may support both the IEEE 802.11ax standard and the IEEE 802.11be standard.
[0046] Referring to Table 1, the second information identifier in the EHT UL MU power capability information element may correspond to RelativeMAX transmit power EHT / HE MCS 12 (relative maximum transmit power EHT / HE MCS 12) and RelativeMAX transmit power EHT / HE MCS13 (relative maximum transmit power EHT / HE MCS 13). That is, RelativeMAX transmit power EHT / HE MCS12 and Relative MAX transmit power EHT / HE MCS 13 may correspond to the 4096QAM modulation mode.
[0047] In Table 1, the relative maximum transmit power EHT / HE-MCS n (where n=1, ..., 13) is an unsigned integer in dB, and when using an HE TB PPDU with a resource unit (RU) size greater than or equal to 242 subcarriers, each relative maximum transmit power EHT / HE-MCS n contains the difference (in dBm) between the maximum transmit power for HE-MCS 0 and the maximum transmit power for HE-MCS n.
[0048] In an embodiment of the present disclosure, even if the station cannot support a certain / certain EHT / HE MCS, its corresponding field may be retained. In another embodiment of the present disclosure, the station may only retain the field of the EHT / HE MCS that it can support. That is, the EHT UL MU power capability information element may include at least part of the first information identifier and the second information identifier.
[0049] Hereinafter, an embodiment in which the EHT UL MU power capability information element is encapsulated in the first message frame will be described in detail.
[0050] In an embodiment of the present disclosure, the EHT UL MU power capability information element may be a multi-link device level. In this case, the station may carry the EHT UL MU power capability information element in a first message frame (e.g., an association request frame or a reassociation request frame). For example, the EHT UL MU power capability information element may be included in a frame body of the first message frame.
[0051] In an example where the first message frame is an association request frame, when the association request frame carries the EHT UL MU power capability information element, as an example, the frame body of the association request frame may be as shown in Table 2 below.
[0052] Table 2. Associtation Request frame body
[0053]
[0054] The order in Table 2 indicates the position of the corresponding capability in the association request frame, and the order not shown (e.g., 13) indicates the position occupied by other standards. According to an embodiment, the order of the EHT UL MU power capability information element may be defined as 49, that is, the 49th position in the association request frame may be the EHT UL MU power capability information element shown in Table 1, however, this order / position is only exemplary, and the EHT UL MU power capability information element may be located at other suitable positions in the frame body of the first message frame. For example, in order to consider the coexistence problem, that is, a device supporting the IEEE 802.11ax standard and a device supporting the IEEE 802.11be standard exist in the same BSS, the ULMU power capability information element may also be reused, that is, the 48th position in the frame body may be reused, in which case the 49th position may be omitted in Table 2.
[0055] In the example where the first message frame is a reassociation request frame, when the reassociation request frame carries the EHT UL MU power capability information element, as an example, the frame body of the reassociation request frame may be as shown in Table 3 below.
[0056] Table 3. Re-Associtation Request frame body
[0057]
[0058] In Table 3, the order of the EHT UL MU power capability information element may be defined as 54, that is, the 54th position in the reassociation request frame may be the EHT UL MU power capability information element shown in Table 1, however, this order / position is only exemplary, and the EHT UL MU power capability information element may be located at other suitable positions in the frame body of the first message frame. For example, in order to consider the coexistence problem, that is, a device supporting the IEEE 802.11ax standard and a device supporting the IEEE 802.11be standard exist in the same BSS, the UL MU power capability information element may also be reused, that is, the 54th position in the frame body may be reused, in which case the 54th position may be omitted in Table 3.
[0059] In another embodiment of the present disclosure, the EHT UL MU power capability information element may be at a link level. In this case, the EHT UL MU power capability information element may be encapsulated in a multi-connection information element (MLelement) field of a first message frame, and the multi-connection information element may be set in the first message frame, for example, the multi-connection information element field may be an element information field with a variable length of the first message frame (e.g., an association request frame and a reassociation request frame). The multi-connection information element may be used to indicate configuration information of multiple connections supported by a station, and its specific format may be as shown in Table 4 below.
[0060] Table 4. ML Element format
[0061]
[0062] In Table 4, the EHT UL MU power capability information element may be a sub-element of the multi-connectivity information element, that is, the EHT UL MU power capability information element having the format shown in Table 1 may be encapsulated in an optional sub-element (OptionalSubelements). As an example, the optional sub-element (OptionalSubelements) may have a format as shown in Table 5 below.
[0063] Table 5. Optional Subelements format
[0064]
[0065] In Table 5, the sub-elements of the multi-connection element field may include a link identifier (Link ID), a complete profile (Complete Profile), and an EHT UL MU power capability information element. In the example of the present disclosure, the link identifier included in the multi-connection information element may be used to indicate the connection for sending the first message frame. The complete profile (Complete Profile) may be used to indicate the entire properties of the station. The EHT UL MU power capability information element may have the format and content shown in Table 1.
[0066] In the case where a station STA supporting the IEEE802.11be standard communicates with an access point AP supporting the IEEE802.11ax standard (for example, when they make an initial association connection), although the station STA can support 4096QAM, the access point AP does not support it. Therefore, the uplink multi-user power capability information element carried in the first message frame may only include: the first information identifier related to the relative maximum transmit power of the QPSK, 16-QAM, 64-QAM, 256-QAM and 1024-QAM modulation modes, that is, the uplink multi-user power capability information element shown in the following Table 6. Similar to the examples described in Tables 2 to 5, the uplink multi-user power capability information element shown in Table 6 can also be encapsulated in the first message frame. For simplicity, the repeated description is omitted here.

[0068]
[0069] Return to reference Figure 2 In step 220, the first message frame determined in step 210 may be sent. For example, the station may send a first message frame encapsulating the uplink multi-user power capability information element shown in Table 1 or Table 6 to the access point. When the access point receives the first message frame, it may reasonably plan uplink resources according to the uplink multi-user power capability information element to improve spectrum efficiency and network throughput.

[0073] The first message frame and the uplink multi-user power capability information element may be similar to the descriptions above with reference to Tables 1 to 6. For the sake of brevity, repeated descriptions are omitted here.
[0074] In step 320, uplink resources may be planned according to the uplink multi-user power capability information element. Various strategies and schemes may be used to plan uplink resources, which are not specifically limited in the embodiments of the present disclosure.
