Description
TECHNICAL FIELD
[0001] The present disclosure relates to the field of communications, and more particularly, to a communication method and a communication apparatus in wireless communications. BACKGROUND
[0002] The current Wi-Fi technology is researched in the range of: 320MHz bandwidth transmission, multiple frequency band aggregation and coordination, etc., and it is expected to improve the rate and throughput by at least four times compared with the existing standard, and the main application scenarios are video transmission, AR(Augmented Reality), VR(Virtual Reality), etc.
[0003] The multiple frequency band aggregation and coordination refers to the communication between devices in the frequency bands of 2.4GHz, 5.8GHz and 6-7GHz at the same time, and a new MAC(Media Access Control) mechanism needs to be defined to manage the communication between devices in multiple frequency bands at the same time.

[0028] Figure 1 This is an exemplary diagram illustrating a wireless communication scenario.
[0029] In a wireless local area network (WLAN), a Basic Service Set (BSS) can consist of at least one station (STA) and an access point (AP). A station (STA) can also be represented as a non-AP. A BSS can connect to a Distribution System (DS) through its APs, and then connect to another BSS to form an Extended Service Set (ESS).
[0030] An Access Point (AP) is a wireless switch used in wireless networks and is the core of a wireless network. An AP can be used as a wireless base station, primarily serving as a bridge connecting wired and wireless networks. Using an AP, wired and wireless networks can be integrated.
[0031] As an example, an access point (AP) may include software applications and / or circuitry to enable other types of nodes in a wireless network to communicate with both the outside and inside of the wireless network via the AP. For instance, an AP may be a terminal device or network device equipped with a Wi-Fi (Wireless Fidelity) chip.
[0032] As an example, a site (non-AP) may include, but is not limited to: cellular phones, smartphones, 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.
[0033] Although Figure 1 The illustration shows one AP communicating with three non-APs (non-AP 1, non-AP 2, non-AP 3), but this is merely exemplary and embodiments of this disclosure are not limited thereto. For example, the number and / or type of APs and non-APs can be any.
[0034] Furthermore, the site (non-AP) and access point (AP) can be a multi-link device (MLD), that is, a device that supports simultaneous transmission and / or reception under multiple connections. Therefore, the communication method and communication apparatus provided according to the embodiments of this disclosure can also be applied to more complex multi-connection communication environments.
[0035] Figure 2 FIG. 8 is a flowchart illustrating a communication method according to an example embodiment of the present disclosure. Figure 2 The communication method described above can be an operation performed at an access point side.
[0036] Referring to Figure 2 In step 210, a first message frame can be determined; in step 220, the first message frame can be transmitted. The first message frame will be described in detail below.
[0037] According to an embodiment, the first message frame can be a beacon frame, however, this is only exemplary, and the present disclosure is not limited thereto, the first message frame can be a management frame, a data frame or a control frame capable of carrying various information and / or data, and embodiments of the present disclosure do not make specific limitations thereon. In embodiments of the present disclosure, there can be many ways to determine the first message frame, for example: the access point can generate the first message frame according to at least one of the following: network conditions, load conditions, hardware capabilities of the transmitting / receiving device, traffic type, relevant protocol provisions; embodiments of the present disclosure do not make specific limitations thereon. In embodiments of the present disclosure, the access point can also obtain the first message frame from an external device, and embodiments of the present disclosure do not make specific limitations thereon.
[0038] According to embodiments of the present disclosure, the first message frame can include a transmit power envelope element. The transmit power envelope element can be used to define the maximum transmit power under each bandwidth. According to embodiments of the present disclosure, the transmit power envelope element can include information indicating the maximum transmit power for 320MHz / 160+160MHz bandwidth. In addition, the transmit power envelope element can also include information indicating the maximum transmit power for at least one of the following bandwidths: 20MHz, 40MHz, 80MHz, 160MHz / 80+80MHz. However, this is only exemplary, and the present disclosure is not limited thereto, the transmit power envelope element can also include information indicating the maximum transmit power for other bandwidths (e.g., 240MHz / 160+80MHz, or other bandwidths to be used for communication).
[0039] According to embodiments of the present disclosure, the transmit power envelope element can include a first identifier indicating a manner of identifying the maximum transmit power.
[0040] According to embodiments of the present disclosure, the transmit power envelope element can also include at least one second identifier indicating the maximum transmit power for a bandwidth.
[0041] According to an embodiment of the present disclosure, the transmit power envelope information element can further comprise a third identification, wherein the third identification is related to a number of the at least one second identification.
[0042] The transmit power envelope information element and its respective identifications will be described in detail below with reference to Tables 1 to 5. It can be understood that each element in Tables 1 to 5 of the present disclosure exists independently, and these elements are exemplarily listed in the same table, but it does not mean that all elements in the table must exist at the same time according to the table. The value of each element is independent of the value of any other element in Tables 1 to 5. 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.
[0043] As an exemplary description, the transmit power envelope information element can have the format shown in Table 1 below.
[0044] Table 1. Transmit power envelope information element
[0045]
[0046] In Table 1, the element identification (Element ID) field and the length (Length) field can be the identity and length of the transmit power envelope information element. The transmit power information (Transmit Power Information) field can comprise the first identification and the third identification described in the above embodiments, and the maximum transmit power (Maximum Transmit Power) field can comprise or correspond to the at least one second identification described in the above embodiments. In an embodiment, the element identification field, the length field and the transmit power information field in the transmit power envelope information element can each have a specific size, for example, 1 octet; and the maximum transmit power field can have a variable size, and the number of the maximum transmit power field is also variable.
[0047] As an exemplary description, the transmit power information field in Table 1 can have the format shown in Table 2 below.
[0048] Table 2. Transmit power information field
[0049]
[0050] In Table 2, the Maximum Transmit Power Count subfield can correspond to the third identification described in the above embodiments, and the Maximum Transmit Power Interpretation subfield can correspond to the first identification described in the above embodiments. As an example, both the Maximum Transmit Power Count subfield and the Maximum Transmit Power Interpretation subfield can have a specific size (for example, but not limited to, 3 bits). In addition, the Maximum Transmit Power Category subfield in Table 2 can indicate the category of the maximum transmit power application, which can be set to a default category, or can depend on the country, for which the present disclosure does not make a specific description. As an example, the Maximum Transmit Power Category subfield can have a specific size (for example, but not limited to, 2 bits).
[0051] In embodiments of the present disclosure, the Maximum Transmit Power Interpretation subfield (first identification) can be used to indicate the way of identifying the maximum transmit power. When the Maximum Transmit Power Interpretation subfield (first identification) is set to different values, it can indicate that the maximum transmit power is identified in different ways, for example, Figure 3 The encoding meaning of the Maximum Transmit Power Interpretation subfield (first identification) is shown.
[0052] Referring to Figure 3 , the Maximum Transmit Power Interpretation subfield (first identification) can indicate that the maximum transmit power of each bandwidth is identified in the way of effective isotropic radiated power (EIRP), as shown by values 0 and 2 in Figure 3 , or indicate that the maximum transmit power of each bandwidth is identified in the way of effective isotropic radiated power (EIPR) power spectral density (PSD), as shown by values 1 and 3 in Figure 3 . The ways are different, the EIRP way identifies the maximum transmit power value under each bandwidth, and the PSD way identifies the maximum transmit power of the corresponding basic channel bandwidth (for example, 20MHz) under one BSS bandwidth. It will be understood that Figure 3 The examples of the Maximum Transmit Power Interpretation subfield (first identification) shown are only descriptive, not a limitation of the present disclosure.
[0053] According to embodiments of the present disclosure, the format and number of at least one second identification can be defined by the first identification and the third identification.
[0054] In one embodiment, the first identifier (e.g., the maximum transmit power interpretation subdomain in Table 2) is set in a first manner (such as...) Figure 3 When the maximum transmit power is identified by the EIRP corresponding to values 0 and 2 in the table, at least one second identifier (e.g., the maximum transmit power field in Table 1) can be used to indicate the maximum transmit power for each bandwidth. In this case, a third identifier (e.g., the maximum transmit power subfield in Table 2) can be set corresponding to at least one second identifier (e.g., the maximum transmit power field in Table 1).
[0055] Combination Figure 3 , Figure 4 This shows that the first identifier (e.g., the maximum transmit power interpretation subdomain in Table 2) is set to match the first mode EIRP (i.e., Figure 3 The meaning of each value of the third identifier (e.g., the maximum transmit power number subfield in Table 2) corresponding to the values 0 and 2 in the table.
[0056] For example, for the bandwidth of 320MHz / 160+160MHz currently under study, a third identifier (e.g., the maximum transmit power subfield in Table 2) can be set to a first value. In this case, at least one second identifier (e.g., the maximum transmit power field in Table 1) can indicate the maximum transmit power for each of the following bandwidths: 20MHz, 40MHz, 80MHz, 160MHz / 80+80MHz, and 320MHz / 160+160MHz. For example, refer to... Figure 3 and Figure 4 When the value of the first identifier (Maximum Transmit Power Interpretation subfield) is set to 0 or 2, the identifier uses EIRP. For a maximum bandwidth of 320MHz, the value of the third identifier (Maximum Transmit Power Count subfield) can be set to "4" (i.e., the first value). The corresponding bandwidths for the maximum transmission power supported by the identifier are 20MHz, 40MHz, 80MHz, 160 / 80+80MHz, and 320 / 160+160MHz, respectively. In addition, at least one second identifier (Maximum Transmit Power field) can be formatted as follows: Figure 3 As shown.
[0057] In other words, when the first identifier (the maximum transmit power interpretation subdomain in Table 2) is set to correspond to EIRP (such as... Figure 3 The values 0 and 2 in the table) and the third identifier (the maximum transmit power number subfield in Table 2) are set to the first value (e.g., 0 and 2) Figure 4The transmit power envelope information element of the first message frame (as shown in "4") may include multiple second identifiers (the maximum transmit power field in Table 1). For example, the second identifiers (the maximum transmit power field in Table 1) may be as shown in Table 3 below. In Table 3, each second identifier may identify the maximum transmit power of the corresponding bandwidth.
[0058] Table 3. Maximum transmit power domain for the first mode (EIRP)
[0059]
[0060] Reference Figure 4 For other bandwidths, when the first identifier (the maximum transmit power interpretation subdomain in Table 2) is set to correspond to EIRP (such as... Figure 3 When the maximum transmit power is identified in terms of equivalent isotropic radiated power by values 0 and 2 in the table, if the third identifier (the maximum transmit power number subfield in Table 2) is set to "0", the transmit power envelope information element of the first message frame may include one second identifier to define the maximum transmit power with a bandwidth of 20MHz; if the third identifier (the maximum transmit power number subfield in Table 2) is set to "1", the transmit power envelope information element of the first message frame may include two second identifiers to define the maximum transmit power with bandwidths of 20MHz and 40MHz, respectively; if the third identifier (the maximum transmit power number subfield in Table 2) is set to "2", the transmit power envelope information element of the first message frame may include three second identifiers to define the maximum transmit power with bandwidths of 20MHz, 40MHz, and 80MHz, respectively; if the third identifier (the maximum transmit power number subfield in Table 2) is set to "3", the transmit power envelope information element of the first message frame may include four second identifiers to define the maximum transmit power with bandwidths of 20MHz, 40MHz, 80MHz, and 160 / 80+80MHz, respectively.
[0061] Will understand, Figure 4 The values shown in Table 3 and the various bandwidths are merely descriptive examples and not limitations of this disclosure. According to embodiments of this disclosure, the third identifier (the maximum transmit power number subfield in Table 2) may also be set to other values to identify the maximum transmit power of other bandwidths (e.g., bandwidth 240MHz / 160+80MHz, or other bandwidths to be used for communication).
[0062] In another embodiment, the first identifier (e.g., the maximum transmit power interpretation subdomain in Table 2) is set in a second manner (such as... Figure 3In the case where the first identification (e.g., Maximum Transmit Power Interpretation subfield in Table 2) is set to correspond to the second way of EIRP PSD (i.e., the value 1 and 3 in Table 1), the respective value implications of the third identification (e.g., Maximum Transmit Power Count subfield in Table 2) are shown in Table 3.
[0063] Table 3. Respective value implications of the third identification (e.g., Maximum Transmit Power Count subfield in Table 2) in the case where the first identification (e.g., Maximum Transmit Power Interpretation subfield in Table 2) is set to correspond to the second way of EIRP PSD (i.e., the value 1 and 3 in Table 1).
[0064]
[0065] In combination with Figure 3 and Table 4, Figure 5 shows the respective value implications of the third identification (e.g., Maximum Transmit Power Count subfield in Table 2) in the case where the first identification (e.g., Maximum Transmit Power Interpretation subfield in Table 2) is set to correspond to the second way of EIRP PSD (i.e., the value 1 and 3 in Table 1). Figure 3
[0066] For example, for the currently studied bandwidth 320MHz / 160+160MHz, the third identification (e.g., Maximum Transmit Power Count subfield in Table 2) can be set to the second value to indicate that in the case where there are N basic channel bandwidths under the bandwidth 320MHz / 160+160MHz, the number of the at least one second identification is N, and the at least one second identification respectively indicates the maximum transmit power of the N basic channel bandwidths under the bandwidth 320MHz / 160+160MHz, where N is determined by the bandwidth 320MHz / 160+160MHz and the basic channel bandwidth (e.g., 20MHz). For example, referring to Figure 3 and Figure 5 When the value of the first identification (Maximum Transmit Power Interpretation subfield) is set to 1 or 3, the way of identification using EIRP PSD, for supporting a maximum 320MHz bandwidth, the value of the third identification (Maximum Transmit Power Count subfield) can be set to “5” (i.e., the second value), and then the value of N can be set to 16 to identify that there are 16 20MHz PSD formats under the 320MHz / 160+160MHz bandwidth.
[0067] That is, when the first identification (Maximum Transmit Power Interpretation Subfield in Table 2) is set to correspond to EIRP PSD (e.g., values 1 and 3 in Table 2) and the third identification (Maximum Transmit Power Number Subfield in Table 2) is set to a second value (e.g., "5" in Table 2), the transmit power envelope information element of the first message frame can include a plurality of second identifications (Maximum Transmit Power field in Table 1), for example, the format of the second identification (Maximum Transmit Power field) can be shown in Table 5 below. In Table 5, each second identification can identify the maximum transmit power (i.e., power spectral density, PSD) of the basic channel bandwidth at a corresponding bandwidth. Figure 3 Figure 4
[0068] Table 5. Second identification (Maximum Transmit Power) at bandwidth 320MHz / 160+160MHz
[0069]
[0070] Referring to Table 5, when the supported bandwidth is 320MHz, the maximum transmit power PSD 1 to the maximum transmit power PSD 16 can respectively indicate the PSD of the 20MHz channel from the lowest frequency to the highest frequency within the bandwidth 320MHz; when the supported bandwidth is 160+160MHz, the maximum transmit power PSD 1 to the maximum transmit power PSD 8 can respectively indicate the PSD of the 20MHz channel from the lowest frequency to the highest frequency within the 160MHz of the low frequency band, and the maximum transmit power PSD 9 to the maximum transmit power PSD 16 can respectively indicate the PSD of the 20MHz channel from the lowest frequency to the highest frequency within the 160MHz of the high frequency band. It will be understood that the example described herein with reference to Table 5 is only illustrative, and not a limitation of the present disclosure, and the number of PSDs corresponding to the second identification can be different according to the basic channel bandwidth of other sizes.
[0071] Referring to Figure 5 , when the first identification (Maximum Transmit Power Interpretation Subfield in Table 2) is set to correspond to EIRP PSD (e.g., values 1 and 3 in Table 2) and the third identification (Maximum Transmit Power Number Subfield in Table 2) is set to a second value (e.g., "5" in Table 2), the transmit power envelope information element of the first message frame can include a plurality of second identifications (Maximum Transmit Power field in Table 1), for example, the format of the second identification (Maximum Transmit Power field) can be shown in Table 5 below. In Table 5, each second identification can identify the maximum transmit power (i.e., power spectral density, PSD) of the basic channel bandwidth at a corresponding bandwidth. Figure 3 If the third identification (Maximum number of transmit power subfields in Table 2) is set to "0", N is 0, and the transmit power envelope information element of the first message frame can include a second identification (a Maximum Transmit PSD subfield) indicating the maximum transmit PSD of a PPDU of any bandwidth within the BSS bandwidth; if the third identification (Maximum number of transmit power subfields in Table 2) is set to "1", N is 1, i.e., the transmit power envelope information element of the first message frame can include a second identification defining a PSD format of 1 20MHz within a bandwidth of 20MHz; if the third identification (Maximum number of transmit power subfields in Table 2) is set to "2", N is 2, i.e., the transmit power envelope information element of the first message frame can include two second identifications defining a PSD format of 2 basic channel bandwidths (20MHz) within a bandwidth of 40MHz; if the third identification (Maximum number of transmit power subfields in Table 2) is set to "3", N is 4, i.e., the transmit power envelope information element of the first message frame can include four second identifications defining a PSD format of 4 20MHz within a bandwidth of 80MHz; if the third identification (Maximum number of transmit power subfields in Table 2) is set to "4", N is 8, i.e., the transmit power envelope information element of the first message frame can include eight second identifications defining a PSD format of 8 20MHz within a bandwidth of 160 / 80+80MHz.
[0072] It will be understood that Figure 5 The values shown in Table 2 are merely descriptive examples, and are not a limitation of the present disclosure, and other values of the third identification (Maximum number of transmit power subfields in Table 2) can also be set according to embodiments of the present disclosure to identify the maximum transmit PSD of each basic channel bandwidth within other bandwidths (e.g., a bandwidth of 240MHz / 160+80MHz, or other bandwidths to be used for communication).
[0073] According to embodiments of the present disclosure, the maximum transmit power within a maximum bandwidth of 320MHz / 160+160MHz can be defined, meeting current communication requirements and improving spectrum utilization.
[0074] Figure 6 is a flow chart illustrating another communication method according to embodiments of the present disclosure. Figure 6 The communication method shown can be operations performed at a station side.
[0075] Referring to Figure 6In step 610, a first message frame can be received. According to an embodiment, the first message frame can comprise a transmit power envelope information element, wherein the transmit power envelope information element can comprise information indicating a maximum transmit power for a bandwidth 320MHz / 160+160MHz.
[0076] According to an embodiment, the transmit power envelope information element can further comprise information indicating a maximum transmit power for at least one of the bandwidths 20MHz, 40MHz, 80MHz, 160MHz / 80+80MHz.
[0077] According to an embodiment, the transmit power envelope information element comprises a first identification indicating a manner of identifying the maximum transmit power.
[0078] According to an embodiment, the transmit power envelope information element further comprises at least one second identification indicating the maximum transmit power with respect to the bandwidth.
[0079] According to an embodiment, the transmit power envelope information element further comprises a third identification, wherein the third identification is related to a number of the at least one second identification.
[0080] According to an embodiment, in a case that the first identification is set to identify the maximum transmit power in a first manner, the at least one second identification is respectively used to indicate the maximum transmit power for each bandwidth. According to an embodiment, the first manner is a manner of equivalent isotropically radiated power (EIRP). In this case, in a case that the third identification is set to a first value, the at least one second identification respectively indicates the maximum transmit power for each of the bandwidths 20MHz, 40MHz, 80MHz, 160MHz / 80+80MHz, and 320MHz / 160+160MHz.
[0081] According to an embodiment, in a case that the first identification is set to identify the maximum transmit power in a second manner, the at least one second identification is respectively used to indicate the maximum transmit power for a corresponding basic channel bandwidth under each bandwidth. The second manner is a manner of equivalent isotropically radiated power (EIRP) power spectral density (PSD). In this case, in a case that the third identification is set to a second value to indicate that there are N basic channel bandwidths under the bandwidth 320MHz / 160+160MHz, the number of the at least one second identification is N, and the at least one second identification respectively indicates the maximum transmit power for the N basic channel bandwidths under the bandwidth 320MHz / 160+160MHz, wherein N is determined by the bandwidth 320MHz / 160+160MHz and the basic channel bandwidth.
[0082] the above-mentioned reference to Table 1 to Table 5, and Figure 3 to Figure 5Examples of the described transmit power envelope information elements, first identifier, second identifier, and third identifier can also be applied to step 610. To avoid redundancy, repeated descriptions are omitted here.
[0083] Continue to refer to Figure 6 In step 620, communication operations can be performed based on the first message frame. For example, when a station receives the first message frame from the access point, it can determine the maximum transmit power under each bandwidth based on the transmit power envelope information element carried in the first message frame, thereby appropriately controlling its transmit power in subsequent data transmission to avoid interference between devices and save power.
