[0087] Figure 1 is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure.

[0088] As shown in Figure 1, the communication system 100 includes a first device 101 and a second device 102, which can be an access point device (AP MLD) 101, a site device (Non-Access Point, Non-AP), an access point multi-link device (AP MLD), and a multi-link site device (Non-Access Point Multi-Link Device, Non-AP MLD), respectively.

[0089] In some embodiments, the access point device can be an access point for mobile terminals to access a wired network. An AP acts as a bridge connecting wired and wireless networks, its main function being to connect various wireless network clients together and then connect the wireless network to the Ethernet. Specifically, an AP can be a terminal device or network device with a Wi-Fi chip. Optionally, the AP can support various WLAN standards such as 802.11ax, 802.11be, 802.11ac, 802.11n, 802.11g, 802.11b, 802.11a, 802.11bf, and 802.11bn, as well as the next-generation 802.11 protocol, but is not limited to these.

[0090] In some embodiments, the site equipment includes, for example, a wireless communication chip, a wireless sensor, or a wireless communication terminal that supports Wi-Fi communication. Optionally, the wireless communication terminal may be at least one of, but is not limited to, a mobile phone, a wearable device, an IoT device that supports Wi-Fi communication, a car with Wi-Fi communication capabilities, a smart car, a tablet computer, a computer with wireless transceiver capabilities, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, and a wireless terminal device in a smart home.

[0091] Specifically, the site equipment can be a terminal device or network device with a Wi-Fi chip. Optionally, the site equipment can support multiple WLAN standards such as 802.11ax, 802.11be, 802.11ac, 802.11n, 802.11g, 802.11b, 802.11a, 802.11bf, and 802.11bn, as well as the next-generation 802.11 protocol, but is not limited to these.

[0092] Optionally, in this embodiment of the disclosure, AP and STA can be devices that support multiple links. For example, they can be represented as Access Point Multi-Link Device (AP MLD) and Non-Access Point Multi-Link Device (Non-AP MLD), respectively. AP MLD can represent an access point that supports multiple link communication functions, and non-AP MLD can represent a site that supports multiple link communication functions.

[0093] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.

[0094] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1 are illustrative. The communication system may include all or some of the main bodies in FIG1, or may include other main bodies outside of FIG1. ​​The number and form of each main body are arbitrary. Each main body may be physical or virtual. The connection relationship between the main bodies is illustrative. The main bodies may not be connected or may be connected. The connection can be in any way, it can be a direct connection or an indirect connection, it can be a wired connection or a wireless connection.

[0095] The embodiments disclosed herein can be applied to Wireless Local Area Networks (WLANs), such as LANs using the 802.11 series of protocols. In a WLAN, a Basic Service Set (BSS) is a fundamental component. An BSS network consists of site devices with some association within a specific coverage area. One type of association is where sites communicate directly with each other in a self-organizing network; this is called an Independent Basic Service Set (IBSS). Another more common scenario is that in a BSS network, there is only one central site dedicated to managing the BSS, called an Access Point (AP) device, while other sites in the BSS network that are not APs are called terminals, also known as non-AP STAs. APs and non-AP STAs are collectively referred to as STAs. When describing STAs, it is not necessary to distinguish between APs and non-AP STAs. Within the same BSS network, due to distance, transmission power, etc., a STA cannot detect other STAs that are far away; they are each other's hidden nodes.

[0096] Figure 2 is one of the interactive schematic diagrams of a channel measurement method according to an embodiment of the present disclosure. As shown in Figure 2, the method includes:

[0097] Step 201, the first device 101 determines the first radio frame; wherein, the first radio frame identifies the dRU information allocated by the first device for channel measurement;

[0098] The dRU information is determined based on the working channel bandwidth of the second device and the channel puncturing information corresponding to the working channel bandwidth; the working channel bandwidth is greater than or equal to 160MHz.

[0099] In WLAN communication scenarios, a channel measurement (sounding) mechanism is employed to enable devices to better utilize resources for communication. The sounding process is used to acquire Channel State Information (CSI), thereby optimizing the performance of Multiple Input Multiple Output (MIMO) communication.

[0100] Furthermore, in WLANs, maximum transmit power and maximum power spectral density may be limited. The limitation on maximum power spectral density is more stringent than that on maximum transmit power. The maximum allowable transmit power is typically more constrained by power spectral density. Therefore, the transmit power of a single contiguous resource unit (RU) is limited by the maximum power spectral density. Distributed resource units (dRUs) enable an increase in transmit power without altering the power spectral density. Specifically, for a dRU and a contiguous RU containing the same number of subcarriers, the bandwidth spanned by the dRU in the frequency domain from a low-frequency start position to a high-frequency end position is greater than the bandwidth occupied by the contiguous RU. Thus, with the same maximum power spectral density, the total transmit power of the dRU is higher than that of the contiguous RU. In other words, when power spectral density is limited, distributing a finite number of subcarriers (e.g., the 26 subcarriers contained in a contiguous 26-tone RU) across a wider bandwidth, i.e., more subcarriers (e.g., the odd number of subcarriers in two contiguous 26-tone RUs), can increase transmit power. Therefore, compared to continuous RUs, using discrete RUs for data transmission can increase the transmit power of a single RU, thereby increasing the transmit power on a single subcarrier and thus improving the signal-to-noise ratio (SNR).

[0101] In this embodiment of the disclosure, to further enhance the sounding mechanism, a first device determines a first radio frame; wherein the first radio frame identifies dRU information allocated by the first device for channel measurement. The first device is, for example, a beamformer; if the first device identifies the dRU information allocated for sounding in the first radio frame, then the dRU indicated by the dRU information is a dRU used for channel measurement, that is, channel measurement is performed using a dRU to optimize the channel measurement process.

[0102] Specifically, the dRU information is determined based on the operating channel bandwidth of the second device and the channel puncturing information corresponding to the operating channel bandwidth; the second device is, for example, a beamforming receiver; the operating channel bandwidth is greater than or equal to 160MHz; for example, 160MHz, 320MHz, or 640MHz, etc.

[0103] It is understood that in this embodiment of the disclosure, the first device is informed in advance of the second device's support capability information for partial bandwidth; for example, the second device carries its partial bandwidth support capability information in other wireless frames and sends it to the first device; or, the first device actively requests the second device to report its partial bandwidth support capability information. Support capability information, for example, includes support for partial 320MHz or 160MHz reception, support for partial 320MHz or 160MHz transmission, etc.

[0104] In this embodiment of the disclosure, different operating channel bandwidths can correspond to different channel puncturing types. For example, for 160MHz and 320MHz Physical Layer Protocol Data Units (PPDUs), in an 80MHz frequency subblock, if one of the 20MHz channels is punctured, the dRU allows the following bandwidth allocation mode 1:

[0105] 20MHz+40MHz (or 40MHz+20MHz) mode; that is, in the 80MHz frequency sub-block, the first 20MHz frequency sub-block is punched or the second 20MHz frequency sub-block is punched.

[0106] Alternatively, for Physical Layer Protocol Data Units (PPDUs) of 160MHz and 320MHz, in an 80MHz frequency subblock, if one of the 40MHz channels is punctured, the dRU allows the following bandwidth allocation mode 2:

[0107] 40MHz mode; that is, in the 80MHz frequency sub-block, the first 40MHz frequency sub-block is punched or the second 40MHz frequency sub-block is punched.

[0108] Thus, when allocating dRUs for channel measurement, the first device should allocate them in sub-blocks that have not been punctured; therefore, when allocating dRUs, the channel puncturing information corresponding to the working channel bandwidth of the second device should be determined, and dRUs should be allocated in sub-blocks (or channels) that have not been punctured based on the channel puncturing information.

[0109] It is understood that in the embodiments of this disclosure, the descriptions of the first 40MHz bandwidth, the first 20MHz bandwidth, and the like are arranged in the frequency domain from the low-frequency start position to the high-frequency end position.

[0110] Step 202: The first device sends the first wireless frame.

[0111] In this way, after receiving the first radio frame, the second device performs channel measurement according to the dRU information identified in the first radio frame; for example, the first radio frame may be a Null Data Packet Announcement (NDPA) frame. After receiving the NDPA frame, the second device receives a Null Data Packet (NDP) frame on the corresponding dRU according to the first identification information. The NDP frame does not contain a data portion and is only used for channel measurement.

[0112] In this embodiment of the disclosure, the first device carries dRU information allocated for channel measurement in the first radio frame, and the dRU information is determined according to the working channel bandwidth of the second device and the channel puncturing information corresponding to the working channel bandwidth, so as to realize the use of dRU for channel measurement under a large bandwidth (e.g., a working channel bandwidth greater than or equal to 160MHz) to meet UHR requirements.

[0113] In some embodiments, when the channel measurement bandwidth is greater than or equal to 160MHz, the channel measurement is performed using a dRU with an 80MHz subblock as the basic unit.

[0114] In some embodiments, the dRU information includes at least one of the following cases 1 to 4:

[0115] Case 1: The working channel bandwidth is 160MHz, the basic puncturing bandwidth indicated by the channel puncturing information is 40MHz (bandwidth mode 2), and the dRU information indicates whether dRU is used in the first 40MHz bandwidth or the second 40MHz bandwidth.

[0116] For example, if the working channel bandwidth is 160MHz and the channel measurement is performed using an 80MHz subblock as the basic unit, and the basic punching bandwidth is 40MHz, then dRU can be used in the first 40MHz bandwidth or the second 40MHz bandwidth.

[0117] Specifically, dRUs are used in the first 40MHz bandwidth, meaning that dRUs are allocated in the first 40MHz bandwidth for the sounding process. This means that punctured channels may or may not exist in the first 40MHz bandwidth. For example, the channel puncturing information identified by the dRU information may include, but is not limited to:

[0118] Sequence 1-1: 0011 1111; Sequence 1-2: 0011 0011; Sequence 1-3: 1100 1111; Sequence 1-4: 11001100.

[0119] Specifically, taking the channel puncturing information as sequence 1-1 as an example, its specific meaning is shown in Table 1 below:

[0120] Table 1:

[0121] As shown in Table 1, channel puncturing was performed in the first and second 20MHz bandwidths. Therefore, subsequent channel measurements can be performed in the bandwidths other than the first and second 20MHz bandwidths, i.e., in the unpunctured bandwidth portions. For example, after receiving an NDPA frame, the second device, based on the first identification information, receives NDPA frames in the corresponding third to eighth 20MHz bandwidths.

[0122] It is understandable that the cases of sequences 1-2 to 1-4 can be referred to as sequence 1-1, and will not be repeated here.

[0123] Specifically, dRUs are used in the second 40MHz bandwidth, meaning that dRUs are allocated in the second 40MHz bandwidth for the sounding process. This implies that punctured channels may or may not exist in the second 40MHz bandwidth. For example, the channel puncturing information identified by the dRU information may include, but is not limited to:

[0124] Sequence 1-5: 1111 0011; Sequence 1-6: 1111 1100.

[0125] Case 2, the working channel bandwidth is 320MHz, the basic puncturing bandwidth indicated by the channel puncturing information is 40MHz (bandwidth mode 2), and the dRU information uses dRU in identifying at least one 40MHz bandwidth.

[0126] For example, if the working channel bandwidth is 320MHz and the channel measurement is performed using an 80MHz subblock as the basic unit, then if the basic puncturing bandwidth is 40MHz, then dRU can be used in at least one 40MHz bandwidth.

[0127] Specifically, taking the use of dRU in the first 40MHz bandwidth as an example, that is, dRU is allocated in the first 40MHz bandwidth for the sounding process. In other words, there may or may not be a punctured channel in the first 40MHz bandwidth. The dRU sequence can start with 0011 or 1100. The corresponding sequence combinations are: 0011+……+1111; or 1100+……+1111. Among them, “……” indicates the sequences from the second 40MHz bandwidth to the seventh 40MHz bandwidth, which can be combined arbitrarily, and will not be listed one by one here.

[0128] For example, taking the sequence combination as 0011+……+1111 as an example, the channel puncturing information identified by the dRU information can include, but is not limited to:

[0129] Sequence 2-1: 0011 1111 1111 1111;

[0130] Sequence 2-2: 0011 1100 1111 1111;

[0131] Sequence 2-3: 0011 1111 0011 1111;

[0132] Sequence 2-4: 0011 1111 1100 1111;

[0133] For example, taking the sequence combination as 1100+...+1111, the channel puncturing information identified by the dRU information can include, but is not limited to:

[0134] Sequence 2-5: 1100 1111 1111 1111;

[0135] Sequence 2-6: 1100 1100 1111 1111;

[0136] Sequence 2-7: 1100 1111 0011 1111;

[0137] Sequence 2-8: 1100 1111 1100 1111;

[0138] Specifically, taking the channel puncturing information as sequence 2-1 as an example, its specific meaning is shown in Table 2 below:

[0139] Table 2:

[0140] As shown in Table 1, channel puncturing was performed in the first and second 20MHz bandwidths. Therefore, subsequent channel measurements can be performed in the bandwidths other than the first and second 20MHz bandwidths, i.e., in the unpunctured bandwidth portions. For example, after receiving an NDPA frame, the second device, based on the first identification information, receives NDPA frames in the corresponding third to sixteenth 20MHz bandwidths.

[0141] It is understandable that the cases of sequences 2-2 to 2-8 can be referred to as sequence 2-1, and will not be repeated here.

[0142] Case 3, the working channel bandwidth is 160MHz, the basic puncturing bandwidth indicated by the channel puncturing information is 20MHz (bandwidth mode 1), and the dRU information identifies that dRU is used in at least one 20MHz bandwidth;

[0143] For example, if the working channel bandwidth is 160MHz and channel measurement is performed using an 80MHz subblock as the basic unit, and the basic puncturing bandwidth is 20MHz, then dRU can be used in at least one 20MHz bandwidth.

[0144] Specifically, taking the use of dRU in the first 80MHz subblock bandwidth as an example, that is, dRU is allocated in the first 80MHz subblock bandwidth for the sounding process, that is, there is (or may not be) a punctured channel in the first 80MHz subblock bandwidth, which corresponds to the 20MHz+40MHz mode in bandwidth mode 1.

[0145] The corresponding sequence combinations are: 0111+……; or 1110+……; where “……” represents another sequence with a subblock bandwidth of 80MHz, which will not be listed here.

[0146] For example: Sequence 3-1: 0111 (0111 corresponds to the 20MHz+40MHz mode in bandwidth mode 1) 1111;

[0147] Sequence 3-2: 0111 0111.

[0148] Taking the use of dRU in the second 80MHz subblock bandwidth as an example, that is, dRU is allocated in the second 80MHz subblock bandwidth for the sounding process, that is, there is (or may not be) a punctured channel in the second 80MHz subblock, which corresponds to the 40MHz+20MHz mode in bandwidth mode 1.

[0149] The corresponding sequence combinations are: ... + 0111; or ... + 1110; where "..." represents another sequence with a subblock bandwidth of 80MHz, which will not be listed here.

[0150] For example: Sequence 3-3: 1111 1110 (1110, corresponding to the 40MHz+20MHz mode in bandwidth mode 1);

[0151] Sequence 3-4: 1110 1110 (1110, corresponding to the 40MHz+20MHz mode in bandwidth mode 1).

[0152] Specifically, taking the channel puncturing information as sequence 3-1 as an example, its specific meaning is shown in Table 3 below:

[0153] Table 3:

[0154] As shown in Table 3, if channel puncturing was performed in the first 20MHz bandwidth, then subsequent channel measurements can be performed in the bandwidth other than the first 20MHz bandwidth, i.e., in the unpunctured bandwidth portion.

[0155] For example, after receiving an NDPA frame, the second device receives the NDPA frame on the corresponding second to eighth 20MHz bandwidths according to the first identification information.

[0156] It is understandable that the cases of sequences 3-2 to 3-4 can be referred to as sequence 3-1, and will not be repeated here.

[0157] Case 4, the working channel bandwidth is 320MHz, the basic puncturing bandwidth indicated by the channel puncturing information is 20MHz, and the dRU information identifies the use of dRU in at least one 20MHz bandwidth.

[0158] For example, if the working channel bandwidth is 320MHz and the channel measurement is performed using an 80MHz subblock as the basic unit, and the basic punching bandwidth is 20MHz, then dRU can be used in at least one 20MHz bandwidth.

[0159] Specifically, taking the use of dRU in the first 40MHz bandwidth of the first 80MHz subblock as an example, that is, dRU is allocated in the first 40MHz bandwidth for the sounding process, that is, there is (or may not be) a punctured channel in the first 40MHz bandwidth, which corresponds to the 20MHz+40MHz mode in bandwidth mode 1.

[0160] The corresponding sequence combination is: 1110 (corresponding to the 40MHz+20MHz mode in bandwidth mode 1)+……+1111; where “……” represents the second 40MHz bandwidth sequence and the third 40MHz bandwidth sequence, which can be combined arbitrarily, and will not be listed one by one here.

[0161] For example, sequence 4-1: 1110 1111 1111 1111.

[0162] Next, let's consider using dRU in the second 40MHz bandwidth within the first 80MHz subblock. This means allocating dRU in the second 40MHz bandwidth for the sounding process, which is essentially the channel being punctured in the second 40MHz bandwidth (or it may not exist). This corresponds to the 20MHz+40MHz mode in bandwidth mode 1. The corresponding sequence combination is: 0111 (corresponding to the 20MHz+40MHz mode in bandwidth mode 1) + ... + 1111; where "..." indicates the sequence in the second 40MHz bandwidth and the sequence in the third 40MHz bandwidth, which can be combined arbitrarily and will not be listed here.

[0163] For example, sequence 4-2: 0111 1111 1111 1111.

[0164] Specifically, taking the channel puncturing information as sequence 4-1 as an example, its specific meaning is shown in Table 4 below:

[0165] Table 4:

[0166] As shown in Table 4, if channel puncturing was performed in the fourth 20MHz bandwidth, then subsequent channel measurements can be performed in the bandwidth other than the fourth 20MHz bandwidth, i.e., in the unpunctured bandwidth portion.

[0167] In some embodiments, the first radio frame includes first identification information, which includes the index information of the dRU.

[0168] Specifically, an explicit identifier, namely first identifier information, can be carried in the user info field of the first radio frame to identify the aforementioned allocation situation; specifically, the first identifier information may include the index information of the dRU, for example, the index information of the dRU used for channel measurement; for example, it may include the index value of the dRU.

[0169] Figure 3 is a second interactive schematic diagram of a channel measurement method according to an embodiment of the present disclosure. As shown in Figure 3, the method includes:

[0170] Step 301, the first device determines the first radio frame; wherein, the first radio frame identifies the dRU information allocated by the first device for channel measurement;

[0171] The dRU information is determined based on the working channel bandwidth of the second device and the channel puncturing information corresponding to the working channel bandwidth; the working channel bandwidth is greater than or equal to 160MHz.

[0172] Step 302: The first device sends the first wireless frame.

[0173] Step 303: The first device sends a second radio frame to the second device according to the dRU information; wherein the second radio frame includes second identification information, and the second identification information identifies the dRU occupied by the second radio frame;

[0174] The channel puncturing information corresponding to the second identification information is the same as the channel puncturing information corresponding to the dRU information.

[0175] The first radio frame can be an NDPA frame. After the first device sends the NDPA frame, it sends the second radio frame, such as an NDP frame, on the corresponding dRU according to the first identification information. The NDP frame does not include a data portion and is only used for channel measurement.

[0176] The second radio frame includes second identification information, for example, the U-SIG portion of the second radio frame carries the second identification information to identify the dRU occupied by the second radio frame, which is consistent with the punch-hole bandwidth information corresponding to the dRU information allocated for channel measurement in the first radio frame.

[0177] In some embodiments, the method further includes:

[0178] The first device receives a third radio frame; the third radio frame includes a first information element, which identifies channel puncturing information. The third radio frame may be a frame including the first information element, such as a UHR operation element or an EHT operation element, which identifies the channel puncturing information of the second device and is used to determine the dRU information allocated for channel measurement.

[0179] Figure 4 is a third interactive schematic diagram of a channel measurement method according to an embodiment of the present disclosure. As shown in Figure 4, the method includes:

[0180] Step 401, the first device sends an NDPA frame; the user info field of the NDPA frame carries second identification information;

[0181] The second identification information identifies the dRU information assigned by the first device (e.g., AP) to the second device (e.g., STA).

[0182] Step 402: The first device sends an NDP frame at the location corresponding to the dRU information. The NDP frame is only used for channel measurement and does not include the data part. It may include some fields containing legacy-short training field (L-STF), legacy long training field (L-LTF), and UHR-LTF, UHR-STF, etc.

[0183] Step 403: The second device receives NDP frames on the corresponding dRU and generates channel measurement results by measuring the received signals.

[0184] Step 404: The first device sends a Beamforming Report Poll (BFRP) frame to obtain the channel measurement results.

[0185] Among these, channel measurement results include Channel State Information (CSI), such as parameters including Channel Quality Indicator (CQI).

[0186] In this embodiment of the disclosure, the first device carries dRU information allocated for channel measurement in the first radio frame, and the dRU information is determined according to the working channel bandwidth of the second device and the channel puncturing information corresponding to the working channel bandwidth, so as to realize the use of dRU for channel measurement under a large bandwidth (e.g., a working channel bandwidth greater than or equal to 160MHz) to further improve the channel measurement mechanism.
