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 after the 802.11be standard are designated EHT+.

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

[0004] The embodiments of the present application provide a solution for correctly transmitting an acknowledgment frame by a receiving device.

[0070] Hereinafter, the embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. Although some 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 interpreted as being limited to the embodiments described herein. On the contrary, rather, 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 "comprising" 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 of" should be understood as "at least one embodiment." Terms such as "first," "second," and the like may refer to different objects or the same object.

[0072] In the context of this disclosure, the term "wireless communication system" may be, 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 protocol of the future IEEE 802.11 series. For ease of explanation, the embodiments of this application use WLAN as an example for explanation. The WLAN may include multiple Basic Service Sets (BSS). The nodes in the Basic Service Set include an access point station and a non-access point station (Non-APSTA).

[0073] The term "Access Point (AP)" may also be called an Access Point Station. An AP is a device with wireless transceiver function and may provide services to a base station. An AP may also be called a wireless access point, a hotspot, etc. An AP is an access point used by mobile users to access a wired network, and is mainly deployed in homes, buildings, and campuses with a typical coverage radius of tens to hundreds of meters. Of course, an AP may be deployed outdoors instead. An AP corresponds to a bridge that connects 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 be 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 called 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 a 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 a 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 the basic transmission mode of current wireless communication and is widely applied to various wireless communication systems. Moreover, OFDM is further applied to the transmission mode of fixed network transmission, such as optical fiber, copper stranded wire, and cable. The basic principle of OFDM is to minimize the subcarrier spacing within the allowable range based on the subcarrier orthogonality. This can ensure that multiple parallel paths that do not interfere with each other are formed while improving the frequency utilization efficiency of the system. Also, because OFDM has the above-mentioned characteristics, if the subcarriers of OFDM that do not interfere with each other are assigned to multiple users, multi-user access and data transmission can be realized using OFDM. This is Orthogonal Frequency Division Multiple Access (OFDMA). OFDMA can be used for simultaneous transmission of multi-user data and is an effective method for improving the parallelism of data transmission.

[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 the system throughput and effectively improving the rate of a communication system. In addition, the transmitting end may transmit data to multiple users through multiple spatial streams to implement simultaneous transmission of multi-user (MU) data 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. Prior to 802.11n, only Single User Single Input Single Output (SU-SISO) was supported. Since 802.11n, Single User Multiple Input Multiple Output (SU-MIMO) has been supported. In addition, MU-MIMO has been supported since 802.11ac and 802.11ax. OFDM transmission has been supported in 802.11 standards prior to 802.11ax. 802.11ax and later introduces OFDMA technology, where the entire bandwidth may be divided into one or more Resource Units (RUs). MU-MIMO and OFDMA will be supported in the 802.11be standard, which is currently under research and defines the Extremely High Throughput Multiple User Physical Protocol Data Unit (EHTMU PPDU).

[0078] With the evolution of WLAN802.11, the transmission bandwidth allowed by WLAN802.11 is also gradually changing. The transmission bandwidth allowed by the 802.11a / g standard is 20MHz, the transmission bandwidth allowed by the 802.11n standard is 20MHz or 40MHz, the transmission bandwidth allowed by the 802.11ax standard is 20MHz, 40MHz, 80MHz or 160MHz, and the bandwidth supported by the 802.11be standard is extended to 320MHz. In this case, the peak throughput can be greatly improved, and the transmission rate can be further improved.

[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 in order to effectively use the channels, two 320 MHz channels are designed, 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, which are shown in FIG. 1 as 130 and 140, respectively.

[0080] It can be seen that FIG. 1 shows a 320 MHz bandwidth. In other scenarios, the bandwidth may be another 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 that may be developed in the future.

[0081] In WLAN, channels are generally classified into primary and secondary channels. In the full bandwidth range (e.g., 320 MHz), an AP selects a 20 MHz channel as a primary channel. An 80 MHz channel that includes a 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 a 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 the 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 inform all STAs.

[0082] In the 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 the 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 Fig. 2 may be an AP or a STA, and the receiving device 202 may be an AP or a STA. Although Fig. 2 shows only a single transmitting device 201 and a single receiving device 202, it can 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 there are other scenarios not enumerated in this disclosure.

[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 be performed 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 be performed 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 hereinafter collectively referred to as AP30, and STA321, STA322, and STA323 will be hereinafter collectively referred to as STA32.

[0088] It should be further understood that Figures 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 another network device or terminal device, for example, a wireless relay device, a wireless backhaul device, etc. In addition, in this embodiment of the present disclosure, the number of the transmitting device 201 and the receiving device 202 included in the system 200 and the number of the AP 30 and the STA 32 included in the system 300 are not limited.

[0089] Figure 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 Figure 4 is only an example and not a limitation. In this embodiment of the present disclosure, interaction signaling not shown in Figure 4 may be included, or some signaling shown in Figure 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, the 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 the data frame in this embodiment of the present disclosure is greater than the bandwidth threshold. In some examples, the 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, the data frame may include multiple MU PPDUs. For example, the multiple MU PPDUs may be aggregated PPDUs 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 limited in the present disclosure.

[0092] It can be understood that the bandwidth of the 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, may implement separate MU-MIMO transmission, or may implement OFDMA and MU-MIMO hybrid 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 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, there are 242 tones in a 20 MHz bandwidth, 484 tones in a 40 MHz bandwidth, and 996 tones in an 80 MHz bandwidth.

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

[0096] The maximum allowable amounts of different bandwidths vary 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 block occupied by the data frame may have one type or a combination of multiple types, in other words, the transmission resource block occupied by the data frame may be RU or Multi-RU (MRU). The MRU 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 otherwise.

[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 (a) 4×996 tones + 996 tone MRU (or 5×996 tone MRU), (b) 4×996 tones + 484 tone MRU (or 4×996+484 tone MRU), (c) 4×996 tone RU; (d) 2×996 tones + 996 tones + 484 tone MRU (or 3×996+484 tone MRU), (e) 2×996 tones + 996 tone MRU (or 3×996 tone MRU), (f) 2×996 tones + 484 tone MRU (or 2×996+484 tone MRU), etc.

[0102] It should be noted that the above examples are merely examples and cannot 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. The 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 be used to carry signaling information related to PPDU length, ensure coexistence, etc. RL-SIG 504 indicates a repetition of L-SIG 503. U-SIG 505 is a universal signal field used from EHT onwards. EHT-SIG 506 may carry signaling used to demodulate subsequent data, mainly including 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 a RU allocation subfield, which may include the 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 assignment subfield, identifiers of multiple users in RU assignment order.

[0109] In some embodiments, a 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 protocol version, frame type, subtype, transmission direction, retransmission, power management, etc. For example, for the Frame Type subfield, "10" may indicate that the frame type is a data frame. Duration 602 may indicate the duration that the data frame and its acknowledgement frame occupy the channel. Address 1 603, Address 2 604, Address 3 605, and Address 4 607 may be collectively referred to as address fields and indicate the receiver address, sender address, source address, destination address, etc. of the data frame. Sequence Control 606 may be used to filter repeating 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 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 the TRS information. Specifically, when 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 (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 Receive Power 704 may indicate the uplink receive 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 may 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 a transmission channel that are occupied when a receiving device transmits an acknowledgment frame. In this disclosure, a transmission channel that is occupied when a receiving device transmits an acknowledgment frame may be referred to as a "acknowledgment channel," and a RU or MRU on a transmission channel that is occupied when a receiving device transmits an acknowledgment frame may be referred to as a "acknowledgment resource block."

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

[0118] The RU allocation information may include first indication information and second indication information. The first indication information has a first length, the second indication information has a second length, and the sum of the first length and the second length may be equal to or less than a preset length. The first indication information may indicate a specific 80 MHz channel on a preset bandwidth channel, and the second indication information 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 information may be located at position B0, and the second indication information 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 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 the RU allocation information.

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

[0124] In some implementations, if the bandwidth of the transmission resource block is equal to or less than the 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 the primary 160 MHz channel, the response channel is also determined to be the primary 160 MHz channel. If the transmission resource block is on the 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 equal to or less than the bandwidth threshold, the response channel may be determined based on a preset rule. Optionally, the preset rule may be at least one of the following when the transmission mode is MU-MIMO: (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 in a user group. For a description of the preset rule, please refer to the specific embodiment of the implementation below.

[0126] In some other implementations, when 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 explanation.

[0127] In some embodiments, assuming that the bandwidth of the transmission resource block is equal to 320 MHz, the preconfigured 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 of 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 the high 160 MHz channel or the low 160 MHz channel. Correspondingly, the secondary 160 MHz channel may be the low 160 MHz channel or the high 160 MHz channel.

[0129] Optionally, a 160 MHz channel having more data tones of the transmission resource block may be used as a response channel. For example, if the transmission resource block is a 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 a 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 position of the 160 MHz channel having more data tones of 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 "position of the 160 MHz channel having more data tones of 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 with more data tones of 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 with more data tones of 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 answer the acknowledgement frame / block acknowledgement 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, if the 160 MHz channel with more data tones of the transmission resource block is a primary 160 MHz channel, the PS160 indication information may be determined to be 0, or if the 160 MHz channel with more data tones of the transmission resource block is a secondary 160 MHz channel, the PS160 indication information may be determined to be 1. It should be noted that when the resource block indicated by the RU Allocation field in the TRS information is an RU / MRU of 2×996 tones or less, the transmission resource block is located only on one 160 MHz channel. Therefore, the method for determining the PS160 indication information may also be as follows, and if the 160 MHz channel of the transmission resource block is a 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 4×996 tone RU, the PS160 indication information is 1 regardless of the specific 160 MHz channel that has more data tones of 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 answer the acknowledgement frame / block acknowledgement frame. In some other embodiments, assuming that the bandwidth of the transmission resource block is equal to 480 MHz, the pre-configuration 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, and (7) a 160 MHz channel with more data tones of the transmission resource block.

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

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

[0135] In this manner, in this implementation, a pre-configuration rule may be predefined so that the receiving device determines the response channel. It may be understood that different receiving devices may use different pre-configuration rules. For example, one receiving device may use a primary 160MHz channel as the response channel, and another receiving device may use a secondary 160MHz channel as the response channel. It may be understood that in the case of SU-MIMO transmission, each channel of the full bandwidth may be fully utilized in this implementation, the resource utilization is optimized, and the 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 rules 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 in 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 a maximum value of the 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 RU allocation of the user.

[0140] For example, assume that the common field 516 indicates multiple different tone RUs. In one example, it can be assumed that 2×996+484 tone MRUs and 484 tone RUs 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 predefined location, the response channel may be determined to be a first 160 MHz channel, and conversely, if the location is not a predefined location, the response channel may be determined to be a second 160 MHz channel.

[0143] If the position of the receiving device 202 in 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 medium 160 MHz channel, or a low 160 MHz channel.

[0146] If the location of the receiving device 202 in 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 the second 160 MHz channel is different from the first 160 MHz channel.

[0147] For example, in this embodiment of the disclosure, the pre-determined 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 position of the receiving device 202 is the Pth position in N. Then, if P mod 2 is equal to 0 (mod indicates the remainder), in other words, if P is an even number, the receiving device 202 is in an even position. If PMod2 is not equal to 0, the receiving device 202 is in an odd position.

[0149] In some instances,

[0150] For example, assuming the number of MUs in the MU-MIMO group is eight 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 position. For example, assuming the number of MUs in the MU-MIMO group is eight 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 position.

[0151] In this manner, in this implementation, a pre-setting rule may be predefined 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, the receiving devices in odd positions (the first receiving device, the third receiving device, the fifth receiving device, if any) may use the primary 160MHz channel as the response channel, and the receiving devices in even positions (the second receiving device, the fourth receiving device, the sixth receiving device, if any) may use the secondary 160MHz channel as the response channel. It can be seen that in the case of MU-MIMO transmission, each channel of the full bandwidth can be fully utilized in this implementation, the resource utilization is optimized, and the transmission efficiency of the acknowledgement frame is guaranteed.

[0152] It can be understood that after determining the response channel 420, the receiving device 202 can determine a response resource block based on the RU allocation information. For example, a particular 80 MHz channel in the response channel may be determined based on the position B0 in the RU allocation information, and a particular RU in the 80 MHz channel is further determined based on the 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 the 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 change 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 following uses the receiving device 202 as an example to describe the information transmission method 800. However, this is only an example and is not intended to impose any restrictions 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, the transmission resource block may be a 4×996 tone RU, a 3×996 tone MRU, a 2×996+484 tone MRU, a 3×996+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 the 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 pre-configured 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 having more data tones of a transmission resource block.

[0162] Optionally, it may be determined that the data frame is transmitted in 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 in the MU-MIMO user group may be the location of the receiving device 202 in 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 is 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 acknowledgment 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 transmit the acknowledgement frame correctly, and information transmission efficiency is ensured. In some embodiments of the present disclosure, the receiving device may transmit a block acknowledgement frame at 830, and details are not repeated here.

[0169] 9 is a schematic flow chart 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 uses 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.

[0171] In this embodiment of the present disclosure, the transmission resource block may be any one of a 4×996 tone RU, a 3×996 tone MRU, a 2×996+484 tone MRU, a 3×996+484 tone MRU, and so on.

[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 the 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 pre-configured 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 having more data tones of a transmission resource block.

[0176] Optionally, it may be determined that the data frame is transmitted in 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 in the MU-MIMO user group may be the location of the receiving device in 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 is 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 the specific implementation of 920, similarly refer 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, details are not 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 receive the acknowledgement frame correctly, and information transmission efficiency is ensured. In some embodiments of the present disclosure, the transmitting device may receive the block acknowledgement frame at 930, and details are not repeated here.
