Description

[Technical Field]

[0001] The present disclosure relates to the field of communications, and more particularly to an information transmission method, a communication device, a computer-readable storage medium, and a chip. [Background technology]

[0002] The 802.11 standard for Wireless Local Area Network (WLAN) systems has evolved from 802.11a / b / g to 802.11n, 802.11ac, 802.11ax, and 802.11be. The 802.11ax standard is called High Efficiency (HE), the 802.11be standard is called Extremely High Throughput (EHT), and standards later than 802.11be are designated EHT+.

[0003] When transmitting a data frame to a base station, current access points inform the base station of the resource units to be occupied for transmitting the acknowledgement frame through resource unit allocation. However, with the expansion of available channel bandwidth, current solutions do not allow the base station to determine the specific channel on which the acknowledgement frame will be transmitted. This solution is not perfect. Summary of the Invention [Means for solving the problem]

[0070] Hereinafter, embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. Although several embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure may be implemented in various forms and should not be construed as being limited to the embodiments described herein. On the contrary, these embodiments are provided so that the present disclosure can be thoroughly and completely understood. It should be understood that the accompanying drawings and embodiments of the present disclosure are merely used as examples and are not intended to limit the protection scope of the present disclosure.

[0071] In describing embodiments of the present disclosure, the term "comprises" and similar terms should be understood as an open inclusion, i.e., "including, but not limited to." The term "based on" should be understood as "based at least in part on." The term "one embodiment" or "an embodiment" should be understood as "at least one embodiment." Terms such as "first," "second," etc. may refer to different objects or the same object.

[0072] In the context of this disclosure, the term "wireless communication system" may refer to, for example, a wide area network system or a wireless local area network (WLAN) system. The wireless communication system may support multiple WLAN communication protocols, such as 802.11ac / 802.11ax / 802.11be of the Institute of Electrical and Electronics Engineers (IEEE) 802.11 series protocols, or any future IEEE 802.11 series protocol. For ease of explanation, the embodiments of this application use WLAN as an illustrative example. A WLAN may include multiple basic service sets (BSSs). Nodes in a basic service set include access point stations and non-access point stations (Non-APSTAs).

[0073] The term "access point (AP)" is sometimes referred to as an access point station. An AP is a device with wireless transceiver capabilities and can provide service to a base station. An AP may also be called a wireless access point, hotspot, etc. An AP is an access point used by mobile users to access a wired network and is mainly deployed inside homes, buildings, and campuses with a typical coverage radius of tens to hundreds of meters. Of course, an AP may alternatively be deployed outdoors. An AP corresponds to a bridge connecting wired and wireless networks. The main function of an AP is to connect STAs together and then connect the wireless network to the wired network. Optionally, an AP may be a terminal device or a network device with a Wireless Fidelity (Wi-Fi) chip. For example, an AP may be a communication server, a router, a switch, or a bridge. Optionally, an AP may be a device that supports the 802.11 standard in a current or future network system.

[0074] The term "base station (STA)" may refer to a device having a wireless transceiver function and may access a wireless local area network based on an access point. The STA may be a wireless communication chip, a wireless sensor, or a wireless communication terminal. For example, the STA may also be referred to as a system, a subscriber unit, an access terminal, a mobile base station, a remote base station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent, a user equipment, or user equipment (UE). The STA may be a wireless communication chip, a wireless sensor, or a wireless communication terminal. For example, the STA may be a mobile phone, a tablet computer, a set-top box, a smart television set, a smart wearable device, an in-vehicle communication device, a computer supporting Wi-Fi communication function, etc. Optionally, the STA may be a device supporting the 802.11 standard in a current or future network system.

[0075] The term "Orthogonal Frequency Division Multiplexing (OFDM)" is a fundamental transmission mode in current wireless communications and is widely applied to various wireless communication systems. Furthermore, OFDM is also applied to fixed network transmission, such as optical fiber, copper stranded wire, and cable. The basic principle of OFDM is to minimize subcarrier spacing within a tolerance based on subcarrier orthogonality. This can improve the system's spectral efficiency while ensuring the formation of multiple parallel paths that do not interfere with each other. Due to the aforementioned characteristics of OFDM, if non-interfering OFDM subcarriers are assigned to multiple users, multi-user access and data transmission can be achieved using OFDM. This is called Orthogonal Frequency Division Multiple Access (OFDMA). OFDMA can be used for simultaneous multi-user data transmission and is an effective method for improving data transmission parallelism.

[0076] The term "Multiple Input Multiple Output (MIMO) technology" refers to a technology that uses multiple antennas to generate additional spatial degrees of freedom, multiplying system throughput and effectively improving the rate of a communication system. In addition, a transmitting end may transmit data to multiple users through multiple spatial streams to implement simultaneous multi-user (MU) data transmission and improve the parallelism of data transmission, which may also be referred to as MU-MIMO.

[0077] The 802.11 standard for WLAN systems has evolved from 802.11a / b / g to 802.11n, 802.11ac, 802.11ax, and 802.11be. Standards prior to 802.11n supported only Single User Single Input Single Output (SU-SISO). 802.11n and later supported Single User Multiple Input Multiple Output (SU-MIMO). Additionally, MU-MIMO was supported in 802.11ac and 802.11ax. OFDM transmission was supported in 802.11 standards prior to 802.11ax. 802.11ax and later introduced OFDMA technology, which allows the entire bandwidth to be divided into one or more resource units (RUs). MU-MIMO and OFDMA will be supported in the currently researched 802.11be standard, which defines the Extremely High Throughput Multiple User Physical Protocol Data Unit (EHTMU PPDU).

[0078] As WLAN 802.11 evolves, the transmission bandwidth allowed by WLAN 802.11 is gradually changing. The 802.11a / g standard allows a transmission bandwidth of 20 MHz, the 802.11n standard allows a transmission bandwidth of 20 MHz or 40 MHz, the 802.11ax standard allows a transmission bandwidth of 20 MHz, 40 MHz, 80 MHz, or 160 MHz, and the 802.11be standard supports a bandwidth of 320 MHz. This can significantly improve peak throughput and further increase transmission rates.

[0079] FIG. 1 is a schematic diagram of a 320 MHz channel division 100. Specifically, FIG. 1 shows the channel division of the Unlicensed National Information Infrastructure (U-NII) radio band in the 6 GHz frequency band. FIG. 1 shows an 80 MHz bandwidth 110, a 160 MHz bandwidth 120, a 320 MHz-1 bandwidth 130, and a 320 MHz-2 bandwidth 140. It can be seen that to effectively use the channels, two 320 MHz channels, namely, 320 MHz-1 with a channel center frequency of 31 / 95 / 159 and 320 MHz-2 with a channel center frequency of 63 / 127 / 191, are designed, which are shown in FIG. 1 as 130 and 140, respectively.

[0080] It can be appreciated that Figure 1 shows a 320 MHz bandwidth. In other scenarios, the bandwidth may be a different value. For example, the bandwidth may be extended to a larger value, such as 480 MHz, 640 MHz, or another value, in advanced ultra-high throughput applications that may be developed in the future.

[0081] In WLANs, channels are generally classified into primary and secondary channels. In the entire bandwidth range (e.g., 320 MHz), an AP selects a 20 MHz channel as the primary channel. An 80 MHz channel that includes the primary channel is called a primary 80 MHz channel, and another 80 MHz channel is called a non-primary 80 MHz channel or a secondary 80 MHz channel. A 160 MHz channel that includes the primary channel is called a primary 160 MHz channel, and another 160 MHz channel is called a non-primary 160 MHz channel or a secondary 160 MHz channel. For example, the location of the primary 80 MHz channel (or primary 160 MHz channel) may be selected by the AP when the AP establishes a basic service set (BSS). The AP may transmit its location in a broadcast manner using a beacon frame to notify all STAs.

[0082] In current multi-user transmission, an AP may transmit data for multiple STAs carried in a PPDU. After receiving the data, the STA may transmit an acknowledgement frame to the AP based on Triggered Response Scheduling (TRS) information carried in the data frame. However, when the bandwidth is larger than 160 MHz (e.g., 320 MHz), the STA cannot determine the specific channel on which the acknowledgement frame is transmitted. Therefore, the current solution is not perfect.

[0083] This embodiment of the present application provides a solution for information transmission, in which one specific RU or multiple specific RUs on a specific channel are used to transmit an acknowledgment frame, which can be determined based on the transmission resource blocks that can be occupied by the data frame and the RU allocation information in the data frame, and the accuracy of the transmission can be guaranteed. Hereinafter, the embodiment of the present disclosure will be described in detail with reference to Figures 2 to 12.

[0084] 2 is a schematic diagram of a communication system 200 to which an embodiment of the present disclosure can be applied. As shown in FIG. 2, the system 200 includes a transmitting device 201 and a receiving device 202. The transmitting device 201 may communicate with the receiving device 202 using a wireless network.

[0085] The transmitting device 201 shown in Figure 2 may be an AP or a STA, and the receiving device 202 may be an AP or a STA. Although Figure 2 shows only a single transmitting device 201 and a single receiving device 202, it may be understood that this is not a limitation in this disclosure. For example, the system 200 may include multiple receiving devices 202, the transmitting device 201 may communicate with multiple receiving devices 202, or other scenarios not enumerated in this disclosure may exist.

[0086] FIG. 3 is another schematic diagram of a communication system 300 to which an embodiment of the present disclosure can be applied. FIG. 3 shows two APs, AP 301 and AP 302. FIG. 3 further shows three base stations, STA 321, STA 322, and STA 323. Wireless communication may occur between APs, between APs and STAs, and between STAs according to various standards. This embodiment of the present disclosure may be applied to communication between APs, between STAs, and between APs and STAs. For example, referring to FIG. 3, communication may occur between AP 301 and AP 302, between STA 322 and STA 323, between AP 301 and STA 321, between AP 301 and STA 322, etc. It should be noted that FIG. 3 is merely an example and should not be construed as a limitation on this embodiment of the present disclosure.

[0087] For ease of explanation, AP301 and AP302 will be collectively referred to as AP30 below, and STA321, STA322, and STA323 will be collectively referred to as STA32 below.

[0088] 2 and 3 are merely schematic diagrams of communication systems to which the embodiments of the present disclosure are applicable. The communication system 200 and the communication system 300 may further include other network devices or terminal devices, for example, wireless relay devices, wireless backhaul devices, etc. In addition, in this embodiment of the present disclosure, the number of transmitting devices 201 and receiving devices 202 included in the system 200 and the number of APs 30 and STAs 32 included in the system 300 are not limited.

[0089] 4 is a schematic interaction diagram of an information transmission process 400 according to one embodiment of the present application. The process 400 relates to a transmitting device 201 and a receiving device 202. It can be understood that the communication process shown in FIG. 4 is only an example and not a limitation. In this embodiment of the present disclosure, interaction signaling not shown in FIG. 4 may be included, or some signaling shown in FIG. 4 is omitted.

[0090] In the process 400 , the transmitting device 201 may first transmit a data frame 410 to the receiving device 202 .

[0091] For example, a data frame in this embodiment of the present disclosure may occupy a transmission resource block, and the bandwidth of the transmission resource block may be greater than the bandwidth threshold. In other words, the bandwidth of a data frame in this embodiment of the present disclosure is greater than the bandwidth threshold. In some examples, a data frame may include a single MU PPDU, and the bandwidth of the single MU PPDU is greater than the bandwidth threshold. In some other examples, a data frame may include multiple MU PPDUs. For example, the multiple MU PPDUs may be an aggregated PPDU obtained by aggregating multiple MU PPDUs, and the bandwidth of the aggregated PPDU is greater than the bandwidth threshold. For example, the bandwidth threshold may be 160 MHz, 320 MHz, or another value. This is not a limitation of the present disclosure.

[0092] It can be understood that the bandwidth of a data frame should not exceed the total available bandwidth (abbreviated as total bandwidth). In the example of FIG. 1, the total bandwidth is 320 MHz. In another scenario, the total bandwidth may be another value, for example, 480 MHz. This is not limited in the present disclosure.

[0093] In this embodiment of the present disclosure, the data frame may implement separate OFDMA transmission, separate MU-MIMO transmission, or hybrid OFDMA and MU-MIMO transmission. In some embodiments, the transmission type may be specified in a specific field of the physical layer format of the data frame. The specific field may be, for example, an Extremely High Throughput Signal Field (EHT-SIG).

[0094] In this embodiment of the present disclosure, multiple different RU types may be defined, and the total bandwidth may be divided by RU type. The RU type may indicate the bandwidth occupied by the RU type in the form of tones. Generally, a 20 MHz bandwidth has 242 tones, a 40 MHz bandwidth has 484 tones, and an 80 MHz bandwidth has 996 tones.

[0095] RU types may include 26-tone RU, 52-tone RU, 106-tone RU, 242-tone RU, 484-tone RU, 996-tone RU, 2x996-tone RU, 4x996-tone RU, etc.

[0096] The maximum allowable amount of different bandwidths varies for different RU types, as shown below in Table 1. Although the 4x996 tone RU is not shown in Table 1 below, it can be understood that the 4x996 tone RU corresponds to a 320 MHz bandwidth.

[0097] [Table 1]

[0098] The transmission resource blocks occupied by a data frame may have one type or a combination of multiple types, that is, the transmission resource blocks occupied by a data frame may be RU or Multi-RU (MRU), which may be a combination of at least two RU types.

[0099] In some examples, the bandwidth threshold may be assumed to be 160 MHz, in other words, the bandwidth occupied by a transmission resource block may be greater than 160 MHz, e.g., 320 MHz, 480 MHz, or another case.

[0100] In some embodiments, the bandwidth occupied by the transmission resource block is 320 MHz, in which case the transmission resource block may be any one of the following: (a) 4×996 tone RU, (b) 2×996 tone + 996 tone MRU (or denoted as 3×996 tone MRU), (c) 2×996 tone + 484 tone MRU (or denoted as 2×996 + 484 tone MRU), (d) 2×996 tone + 996 tone + 484 tone MRU (or denoted as 3×996 + 484 tone MRU), etc.

[0101] In some embodiments, the bandwidth occupied by a transmission resource block is 480 MHz. In this case, the transmission resource block is It may be any one of (a) 4 x 996 tones + 996 tone MRU (or written as 5 x 996 tone MRU), (b) 4 x 996 tones + 484 tone MRU (or written as 4 x 996 + 484 tone MRU), (c) 4 x 996 tone RU; (d) 2 x 996 tones + 996 tones + 484 tone MRU (or written as 3 x 996 + 484 tone MRU), (e) 2 x 996 tones + 996 tone MRU (or written as 3 x 996 tone MRU), (f) 2 x 996 tones + 484 tone MRU (or written as 2 x 996 + 484 tone MRU), etc.

[0102] It should be noted that the above examples are merely examples and should not be construed as limitations on this embodiment of the present disclosure. There may be other RUs or MRUs that are not listed.

[0103] In some embodiments, the physical layer format of a data frame may be shown in FIG.

[0104] 5 is a schematic diagram of a physical layer format 500 of a data frame according to one embodiment of the present disclosure. Format 500 includes a Legacy-Short Training Field (L-STF) 501, a Legacy-Long Training Field (L-LTF) 502, a Legacy Signal (L-SIG) 503, a Repeated Legacy-Signal (RL-SIG) 504, a Universal Signal (U-SIG) 505, an Extremely High Throughput Signal Field (EHT-SIG) 506, an Extremely High Throughput Short Training Field (EHT-STF) 507, and an Extremely High Throughput Long Training Field (EHT-LTF) 508. Furthermore, after the data field (Data) 509, there is a packet extension (PE) field 510.

[0105] For example, L-STF 501 may be used for PPDU discovery, coarse synchronization, automatic gain control, etc. L-LTF 502 may be used for fine synchronization, channel estimation, etc. L-SIG 503 may carry signaling information related to PPDU length and may be used to ensure coexistence, etc. RL-SIG 504 indicates a repetition of L-SIG 503. U-SIG 505 is a universal signal field used after EHT. EHT-SIG 506 may carry signaling used to demodulate subsequent data and mainly includes resource unit indication information, etc. EHT-STF 507 may be used for automatic gain control of subsequent fields, etc. EHT-LTF 508 may be used for channel estimation, etc. Data 509 may carry data information. PE 510 may be used to help the receiving device obtain more processing time, etc.

[0106] As shown in FIG. 5, the EHT-SIG 506 may include a Common Field 516 and a User Specific Field 526.

[0107] For example, the common field 516 may include an RU allocation subfield, which may include an RU (or MRU) type and the number of users in the corresponding user group.

[0108] For example, the user specific field 526 may include, within the RU allocation subfield, identifiers of multiple users in RU allocation order.

[0109] In some embodiments, the Media Access Control (MAC) layer format of a data frame may be shown in FIG.

[0110] 6 is a schematic diagram of a MAC layer format 600 of a data frame according to one embodiment of the present disclosure. The format 600 includes a Frame Control 601, a Duration 602, an Address 1 603, an Address 2 604, an Address 3 605, a Sequence Control 606, an Address 4 607, a High Throughput Control (HT Control) 608, a Frame Body 609, and a Frame Check Sequence (FCS) 610.

[0111] For example, frame control 601 may include multiple subfields indicating the protocol version, frame type, subtype, transmission direction, retransmission, power management, etc. For example, for the frame type subfield, a "10" may indicate that the frame type is a data frame. Duration 602 may indicate the duration that the data frame and its acknowledgment frame occupy the channel. Address 1 603, Address 2 604, Address 3 605, and Address 4 607 may collectively be referred to as address fields and indicate the recipient address, sender address, source address, destination address, etc. of the data frame. Sequence control 606 may be used to filter repeated frames. Frame body 609 may carry specific information. FCS 610 may be used for error detection; for example, FCS 610 may include a 32-bit cyclic redundancy check (CRC).

[0112] 6, the HT control 608 may include an aggregated control (A-Control) 680. The aggregated control may include a control list (Control List) 682 and padding 684. The control list 682 may include a control identification (Control ID) 6822, control information 6824, etc.

[0113] In some embodiments of the present disclosure, when the transmitting device 201 transmits the data frame 410, the data frame may carry TRS information. Specifically, if the control identifier 6822 is a preset value (e.g., 0), the corresponding control information 6824 carries the TRS information.

[0114] 7 is a schematic diagram of a TRS information format 700 according to one embodiment of the present disclosure. The format 700 includes uplink data symbols (UL Data Symbols) 701, resource unit allocation (RU Allocation) 702, AP transmit power (AP TX Power) 703, uplink target receive power (UL Target Receive Power) 704, UL Modulation and Coding Set (UL MCS) 705, and reserved 706.

[0115] For example, UL Data Symbols 701 may indicate the length (number of symbols) of the data portion of the acknowledgement frame transmitted by the receiving device. AP Transmit Power 703 may indicate the transmit power of the AP. UL Target Received Power 704 may indicate the uplink received power expected by the AP. ULMCS 705 may indicate the MCS used only by the receiving device to transmit the acknowledgement frame. Reserved 706 may have a reserved length, such as 1 bit.

[0116] For example, the RU allocation 702 may carry RU allocation information indicating frequency locations on a transmission channel that can be occupied by a receiving device to transmit an acknowledgment frame. The frequency locations may be in the form of RUs or MRUs. Specifically, the RU allocation information may indicate specific RUs on the transmission channel that are occupied when the receiving device transmits the acknowledgment frame. In this disclosure, the transmission channel that is occupied when the receiving device transmits the acknowledgment frame may be referred to as an "acknowledgment channel," and the RUs or MRUs on the transmission channel that are occupied when the receiving device transmits the acknowledgment frame may be referred to as "acknowledgment resource blocks."

[0117] In some embodiments of the present disclosure, the RU allocation field 702 may be of a predetermined length and may indicate the RUs on a predetermined bandwidth channel occupied by the receiving device. The predetermined bandwidth may be 160 MHz. It can be understood that the RU allocation information may indicate the location of a response resource block on the 160 MHz channel.

[0118] The RU allocation information may include first and second indications. The first indication may have a first length, and the second indication may have a second length, and the sum of the first and second lengths may be less than or equal to a predetermined length. The first indication may indicate a specific 80 MHz channel on a predetermined bandwidth channel, and the second indication may indicate a specific RU on the corresponding 80 MHz channel.

[0119] In some implementations, the preset length may be 8 bits, the first length may be 1 bit, and the second length may be 7 bits. The first indication may be located at position B0, and the second indication may be located at positions B1-B7.

[0120] In some examples, if the response channel is a primary 160 MHz channel, the first value B0 indicates a primary 80 MHz channel and the second value B0 indicates a secondary 80 MHz channel. Optionally, the first value is 0 and the second value is 1, or the first value is 1 and the second value is 0. In some other examples, if the response channel is a secondary 160 MHz channel, the first value B0 indicates a low 80 MHz channel and the second value B0 indicates a high 80 MHz channel. Optionally, the first value is 0 and the second value is 1, or the first value is 1 and the second value is 0.

[0121] It can be understood that the implementations are merely examples rather than limitations, and that other implementations not shown are not excluded in this embodiment of the disclosure.

[0122] Returning to process 400, the receiving device 202 may determine a response resource block 420 based on the transmission resource block and RU allocation information.

[0123] Specifically, when determining the response resource block 420, the receiving device 202 may first determine the response channel and then determine the response resource block within the response channel. For example, the response channel may be determined based on a preset rule.

[0124] In some implementations, if the bandwidth of a transmission resource block is equal to or less than a bandwidth threshold, the channel of the transmission resource block may be determined to be the response channel. For example, assume that the bandwidth threshold is 160 MHz and the bandwidth of the transmission resource block is equal to 160 MHz. If the transmission resource block is on a primary 160 MHz channel, the response channel is also determined to be the primary 160 MHz channel. If the transmission resource block is on a secondary 160 MHz channel, the response channel is also determined to be the secondary 160 MHz channel.

[0125] In some other implementations, when the bandwidth of the transmission resource block is less than or equal to a bandwidth threshold, the response channel may be determined based on a preset rule. Optionally, when the transmission mode is MU-MIMO, the preset rule may be at least one of the following: (1) a primary 160 MHz channel, (2) a secondary 160 MHz channel, (3) a high 160 MHz channel, (4) a low 160 MHz channel, (5) a 160 MHz channel of the transmission resource block, or (6) a 160 MHz channel corresponding to a position within a user group. For a description of the preset rule, please refer to the specific embodiments of the implementations below.

[0126] In some other implementations, if the bandwidth of the transmission resource block is greater than the bandwidth threshold, the response channel may be determined based on a preset rule. In the following, an example in which the bandwidth threshold is 160 MHz is used for illustration.

[0127] In some embodiments, assuming the bandwidth of the transmission resource block is equal to 320 MHz, the preset rule may be at least one of the following: (1) a primary 160 MHz channel; (2) a secondary 160 MHz channel; (3) a high 160 MHz channel; (4) a low 160 MHz channel; (5) a 160 MHz channel with more data tones in the transmission resource block.

[0128] Optionally, the primary 160 MHz channel may be used as the response channel. Alternatively, the secondary 160 MHz channel may be used as the response channel. Alternatively, the high 160 MHz channel may be used as the response channel. Alternatively, the low 160 MHz channel may be used as the response channel. It may be understood that the primary 160 MHz channel may be either the high 160 MHz channel or the low 160 MHz channel. Correspondingly, the secondary 160 MHz channel may be either the low 160 MHz channel or the high 160 MHz channel.

[0129] Optionally, a 160 MHz channel with more data tones than the transmission resource block may be used as the response channel. For example, if the transmission resource block is an MRU of a certain size, the transmission resource block is one of a 3×996-tone MRU, a 2×996+484-tone MRU, or a 3×996+484-tone MRU. In this case, the 160 MHz channel in which the 2×996-tone RU is located may be used as the response channel. It may be understood that the 160 MHz channel in which the 2×996-tone RU is located may be a high 160 MHz channel or a low 160 MHz channel. The 160 MHz channel in which the 2×996-tone RU is located may be a primary 160 MHz channel or a secondary 160 MHz channel.

[0130] In another implementation, the resource block to which the response frame is returned is determined based on the indication information PS160 and the RU Allocation field in the TRS information. The indication information PS160 is determined based on the location of the 160 MHz channel having more data tones in the transmission resource block and the resource block size indicated by the RU Allocation field in the TRS information. For example, the indication information PS160 is determined based on "the location of the 160 MHz channel having more data tones in the transmission resource block" in the second column of Input in the following table and "the resource block size indicated by the RU Allocation field in the TRS information" in the first column of Input.

[0131] [Table 2]

[0132] For example, if the resource block size indicated by the RU Allocation field in the TRS information is 2 × 996 + 484 tones, If the 160 MHz channel having more data tones in the transmission resource block is a low 160 MHz channel, the indication information PS160 may be determined to be 0. Alternatively, if the 160 MHz channel having more data tones in the transmission resource block is a high 160 MHz channel, the indication information PS160 may be determined to be 1. After determining the indication information PS160, the base station may refer to the RU Allocation field in the TRS information to determine the location of the resource block used to reply to the acknowledgment frame / block acknowledgment frame. As another example, if the resource block indicated by the RU Allocation field in the TRS information is an RU / MRU of 2×996 tones or less, the PS160 indication information may be determined to be 0 if the 160 MHz channel having more data tones in the transmission resource block is a primary 160 MHz channel, or the PS160 indication information may be determined to be 1 if the 160 MHz channel having more data tones in the transmission resource block is a secondary 160 MHz channel. Note that when the resource block indicated by the RU Allocation field in the TRS information is an RU / MRU of 2x996 tones or less, the transmission resource block is located on only one 160 MHz channel. Therefore, the method for determining the PS160 indication information may also be as follows: if the 160 MHz channel of the transmission resource block is the primary 160 MHz channel, the PS160 indication information may be determined to be 0. If the 160 MHz channel of the transmission resource block is a secondary 160 MHz channel, the PS160 indication information may be determined to be 1. For example, if the resource block indicated by the RU Allocation field in the TRS information is a 4x996-tone RU, the PS160 indication information is 1 regardless of the specific 160 MHz channel that has more data tones in the transmission resource block.After determining the indication information PS 160, the base station may refer to the RU Allocation field in the TRS information to determine the location of the resource block used to reply to the acknowledgment frame / block acknowledgment frame. In some other embodiments, assuming that the bandwidth of the transmission resource block is equal to 480 MHz, the preset rule may be at least one of: (1) a primary 160 MHz channel, (2) a secondary 160 MHz channel with a higher frequency, (3) a secondary 160 MHz channel with a lower frequency, (4) a high 160 MHz channel, (5) a middle 160 MHz channel, (6) a low 160 MHz channel, or (7) a 160 MHz channel with more data tones in the transmission resource block.

[0133] It can be understood that the 480 MHz bandwidth can be divided into three 160 MHz channels. In one example, the three 160 MHz channels can include one primary 160 MHz channel and two secondary 160 MHz channels. Of the two secondary 160 MHz channels, one has a higher frequency and the other has a lower frequency. In another example, the three 160 MHz channels can include a high 160 MHz channel, a middle 160 MHz channel, and a low 160 MHz channel. Optionally, any one of the aforementioned 160 MHz channels can be used as a response channel.

[0134] Optionally, a 160 MHz channel with more data tones in the transmission resource block may be used as the response channel. For example, if the transmission resource block is an MRU of a certain size, the 160 MHz channel in which the 2×996-tone RU is located may be used as the response channel. It may be understood that the 160 MHz channel in which the 2×996-tone RU is located may be a high 160 MHz channel, a middle 160 MHz channel, or a low 160 MHz channel.

[0135] In this manner, in this implementation, a preset rule may be predetermined so that the receiving device determines the response channel. It may be understood that different receiving devices may use different preset rules. For example, one receiving device may use a primary 160 MHz channel as the response channel, and another receiving device may use a secondary 160 MHz channel as the response channel. It may be understood that in the case of SU-MIMO transmission, each channel of the entire bandwidth can be fully utilized, resource utilization is optimized, and transmission efficiency of the acknowledgement frame is guaranteed.

[0136] In some other implementations, in the case of MU-MIMO transmission, determining the response channel by the receiving device 202 based on the pre-configured rule may include determining that the data frame is transmitted in MU-MIMO mode based on an EHT-SIG field of the data frame, determining a position of the receiving device 202 within the MU-MIMO user group based on an identifier (ID) of the receiving device 202 in the EHT-SIG field, and determining the response channel based on the position.

[0137] 5, the physical layer format of the data frame includes an EHT-SIG 506, and the transmission mode of the data frame may be determined based on a common field 516 in the EHT-SIG 506. For example, the RU allocation subfield in the common field 516 may further indicate the number of users in the user group. In some examples, the number of MUs may be less than or equal to the number of spatial streams, and the number of spatial streams may indicate the maximum number of MUs.

[0138] For example, the physical layer format of the data frame may include an EHT-SIG 506, and the location may be determined based on a common field 516 and a user-specific field 526 within the EHT-SIG 506.

[0139] The order in which users appear in the user-specific field 526 is consistent with the RU order obtained by division in the corresponding RU allocation subfield. A user may identify whether the user-specific field 526 belongs to a user by reading the ID of the receiving device in the user-specific field 526. Based on the position in which the user-specific field appears and the corresponding resource unit allocation subfield, the user can know the user's RU allocation.

[0140] For example, assume that the common field 516 indicates multiple different tone RUs. In one example, it can be assumed that a 2×996+484-tone MRU and a 484-tone RU are included, the number of users in the user group corresponding to the 2×996+484-tone MRU is 8, and the number of users in the user group corresponding to the 484-tone RU is also 8. Optionally, multiple receiving devices corresponding to the same RU (or MRU) may belong to the same MU-MIMO group. For example, the user group (8) corresponding to the 2×996+484-tone MRU is a first MU-MIMO group, and the user group (8) corresponding to the 484-tone RU is a second MU-MIMO group. In this embodiment of the present disclosure, the position of the receiving device 202 in the MU-MIMO user group may be the position of the receiving device 202 in the MU-MIMO group to which the receiving device 202 belongs.

[0141] The receiving device 202 may determine the first position in all orders (16) based on the user-specific field 526. In one example, assuming the first position is less than or equal to 8 in all orders, e.g., the fifth position, the RU allocation corresponding to the receiving device 202 is 2×996+484-tone MRU, and the position of the receiving device 202 in the MU-MIMO user group to which the receiving device 202 belongs (i.e., the first MU-MIMO group) is 5. Assuming the first position is greater than 8 in all orders, e.g., the twelfth position, the RU allocation corresponding to the receiving device 202 is 484-tone RU, and the position of the receiving device 202 in the MU-MIMO user group to which the receiving device 202 belongs (i.e., the second MU-MIMO group) is 12−8=4.

[0142] For example, if the location is a predetermined location, the response channel may be determined to be a first 160 MHz channel, and conversely, if the location is not a predetermined location, the response channel may be determined to be a second 160 MHz channel.

[0143] If the position of the receiving device 202 within the MU-MIMO group is at a predetermined position, the response channel may be determined to be the first 160 MHz channel.

[0144] In some embodiments, the bandwidth of the transmission resource block is assumed to be equal to 320 MHz. Optionally, the first 160 MHz channel may be a primary 160 MHz channel or a secondary 160 MHz channel. Optionally, the first 160 MHz channel may be a high 160 MHz channel or a low 160 MHz channel.

[0145] In some embodiments, the bandwidth of the transmission resource block is assumed to be equal to 480 MHz. Optionally, the first 160 MHz channel may be a primary 160 MHz channel, a secondary 160 MHz channel having a higher frequency, or a secondary 160 MHz channel having a lower frequency. Optionally, the first 160 MHz channel may be a high 160 MHz channel, a mid 160 MHz channel, or a low 160 MHz channel.

[0146] If the location of the receiving device 202 within the MU-MIMO group is not a predetermined location (i.e., a non-predetermined location), it may be determined that the response channel is a second 160 MHz channel, and that the second 160 MHz channel is different from the first 160 MHz channel.

[0147] For example, in this embodiment of the present disclosure, the predetermined position may be at least one of an odd position, an even position, a first half position, or a second half position.

[0148] For example, assume that the number of MUs in a MU-MIMO group is N, and the location of receiving device 202 is the Pth location in N. Then, if P mod 2 is equal to 0 (mod indicates the remainder), in other words, if P is an even number, receiving device 202 is in an even location. If PMod2 is not equal to 0, receiving device 202 is in an odd location.

[0149] In some instances,

[0150] For example, if the number of MUs in the MU-MIMO group is 8 and the receiving device 202 is located in the fifth position, the receiving device 202 is located in an odd position and in the latter half of the position. For example, if the number of MUs in the MU-MIMO group is 8 and the receiving device 202 is located in the second position, the receiving device 202 is located in an even position and in the former half of the position.

[0151] In this manner, in this implementation, a preset rule may be predetermined so that the receiving device determines the response channel. In addition, different receiving devices in the same MU-MIMO group may determine different response channels. For example, receiving devices in odd positions (the first receiving device, the third receiving device, the fifth receiving device, ... (if any)) may use the primary 160 MHz channel as the response channel, and receiving devices in even positions (the second receiving device, the fourth receiving device, the sixth receiving device, ... (if any)) may use the secondary 160 MHz channel as the response channel. It can be understood that in the case of MU-MIMO transmission, each channel of the entire bandwidth can be fully utilized, resource utilization is optimized, and transmission efficiency of the acknowledgement frame is guaranteed.

[0152] It can be appreciated that after determining the response channel 420, the receiving device 202 can determine the response resource block based on the RU allocation information. For example, a specific 80 MHz channel in the response channel may be determined based on position B0 in the RU allocation information, and a specific RU in the 80 MHz channel may be further determined based on positions B1-B7 in the RU allocation information.

[0153] The receiving device 202 may then transmit an acknowledgment frame for the data frame to the transmitting device 201 on the response resource block.

[0154] In this way, when the transmission resource block of the data frame is larger than the bandwidth threshold, the receiving device can determine the response channel based on a preset rule and then accurately determine the response resource block based on the RU allocation information. This solution is improved. The receiving device knows the specific channel on which the acknowledgment frame is transmitted. In addition, the solution in this embodiment of the present disclosure does not require additional bits for indication. In this case, there is no need to specially modify the format of the data frame, and it is highly applicable.

[0155] 8 is a schematic flowchart of an information transmission method 800 according to an embodiment of the present disclosure. As an example, the method 800 may be implemented on the receiving device 202 shown in FIG. 2. For ease of understanding, the information transmission method 800 will be described below using the receiving device 202 as an example. However, this is merely an example and is not intended to impose any limitations on this embodiment of the present disclosure.

[0156] The method 800 begins at block 810. At 810, the receiving device 202 receives a data frame from a transmitting device. The data frame occupies a transmission resource block and includes RU allocation information.

[0157] In some embodiments, a transmission resource block may be a 4x996 tone RU, a 3x996 tone MRU, a 2x996+484 tone MRU, a 3x996+484 tone MRU, etc. It should be understood that the foregoing examples of transmission resource blocks are illustrative only and not limiting, and that other suitable RUs or MRUs may also be used as transmission resource blocks in this embodiment of the disclosure.

[0158] For example, for a relevant description of the data frame from the transmitting device, please refer to the specific embodiment described above with reference to 410. For the sake of brevity, the details will not be described again here.

[0159] At 820, the receiving device 202 determines a response resource block based on the transmission resource block and RU allocation information.

[0160] In some embodiments, if the bandwidth of the transmission resource block is greater than a bandwidth threshold (e.g., 320 MHz), the response channel may be determined based on a preset rule, and the response resource block may be determined based on the response channel and the RU allocation information. In this embodiment of the present disclosure, the response channel may be a response 160 MHz channel.

[0161] Optionally, the response channel may include at least one of a primary 160 MHz channel, a secondary 160 MHz channel, a high 160 MHz channel, a low 160 MHz channel, or a 160 MHz channel with more data tones in the transmission resource block.

[0162] Optionally, it may be determined that the data frame is transmitted using MU-MIMO based on the EHT-SIG field of the data frame. The location of the receiving device 202 in the MU-MIMO user group may be determined based on the identifier of the receiving device 202 in the EHT-SIG field. The response channel may be determined based on the location.

[0163] For example, the location of the receiving device 202 within the MU-MIMO user group may be the location of the receiving device 202 within the MU-MIMO group. If the location is a predetermined location, the response channel may be determined to be a first 160 MHz channel. If the location is not a predetermined location (i.e., a non-predetermined location), the response channel may be determined to be a second 160 MHz channel. Optionally, the second 160 MHz channel is different from the first 160 MHz channel.

[0164] Optionally, the first 160 MHz channel may be a primary 160 MHz channel or a secondary 160 MHz channel. Optionally, the first 160 MHz channel may be a high 160 MHz channel or a low 160 MHz channel.

[0165] In some examples, the first 160 MHz channel is a primary 160 MHz channel and the second 160 MHz channel is a secondary 160 MHz channel, hi other examples, the first 160 MHz channel is a high 160 MHz channel and the second 160 MHz channel is a low 160 MHz channel.

[0166] It should be understood that for a specific implementation of block 820, reference is made to the detailed description of how the receiving device 202 determines the response resource block 420 in the process 400. For the sake of brevity, the details will not be described again here.

[0167] Then, at 830, the receiving device 202 transmits an acknowledgement frame for the data frame to the transmitting device 201 on the response resource block.

[0168] In this way, the receiving device can determine the response channel based on a preset rule, and can then correctly transmit the acknowledgment frame, ensuring information transmission efficiency. In some embodiments of the present disclosure, the receiving device may transmit a block acknowledgment frame at 830, and details will not be repeated here.

[0169] 9 is a schematic flowchart of an information transmission method 900 according to an embodiment of the present invention. As an example, the method 900 may be implemented in the transmitting device 201 shown in FIG. 2. For ease of understanding, the following will use the transmitting device 201 as an example to describe the information transmission method 900. However, this is only an example and is not intended to impose any limitations on this embodiment of the present disclosure.

[0170] At 910, the transmitting device 201 transmits a data frame to the receiving device, where the data frame occupies a transmission resource block and includes RU allocation information.

[0172] For example, for a relevant description of the data frame from the transmitting device, please refer to the specific embodiment described above with reference to 410. For the sake of brevity, the details will not be described again here.

[0173] At 920, the transmitting device 201 determines a response resource block based on the transmission resource block and RU allocation information.

[0174] In some embodiments, if the bandwidth of the transmission resource block is greater than a bandwidth threshold (e.g., 320 MHz), the response channel may be determined based on a preset rule, and the response resource block may be determined based on the response channel and the RU allocation information. In this embodiment of the present disclosure, the response channel may be a response 160 MHz channel.

[0175] Optionally, the response channel may include at least one of a primary 160 MHz channel, a secondary 160 MHz channel, a high 160 MHz channel, a low 160 MHz channel, or a 160 MHz channel with more data tones in the transmission resource block.

[0176] Optionally, it may be determined that the data frame is transmitted using MU-MIMO based on an EHT-SIG field of the data frame. A location of the receiving device in the MU-MIMO user group may be determined based on an identifier of the receiving device in the EHT-SIG field. A response channel may be determined based on the location.

[0177] For example, the location of the receiving device within the MU-MIMO user group may be the location of the receiving device within the MU-MIMO group. If the location is a predetermined location, the response channel may be determined to be a first 160 MHz channel. If the location is not a predetermined location (i.e., a non-predetermined location), the response channel may be determined to be a second 160 MHz channel. Optionally, the second 160 MHz channel is different from the first 160 MHz channel.

[0178] Optionally, the first 160 MHz channel may be a primary 160 MHz channel or a secondary 160 MHz channel. Optionally, the first 160 MHz channel may be a high 160 MHz channel or a low 160 MHz channel.

[0179] In some examples, the first 160 MHz channel is a primary 160 MHz channel and the second 160 MHz channel is a secondary 160 MHz channel, hi other examples, the first 160 MHz channel is a high 160 MHz channel and the second 160 MHz channel is a low 160 MHz channel.

[0180] It can be understood that for specific implementation forms of 920, similar reference can be made to the above detailed description of 420. In other words, the transmitting device 201 and the receiving device 202 may determine a response channel and further determine a response resource block in a similar manner. In this way, the receiving end and the transmitting end can ensure consistency. For the sake of brevity, the details will not be described again here.

[0181] Next, at 930, the transmitting device 201 receives an acknowledgment frame for the data frame from the receiving device 202 on the response resource block.

[0182] In this way, the transmitting device can determine the response channel based on a preset rule, and can correctly receive the acknowledgment frame, ensuring information transmission efficiency. In some embodiments of the present disclosure, the transmitting device may receive the block acknowledgment frame at 930, and details will not be repeated here.
