Description

Technical Field

[0001] This invention relates to the field of wireless communication, and in particular to a wireless communication method, a wireless device, and a computer storage medium. Background Technology

[0002] The current BLE (Bluetooth Low Energy) protocol operates in the 2.4GHz band. In the future, BLE devices can operate in higher bands (HB, Higher Bands), such as 5GHz and 6GHz. Under current spectrum resource management, different regions have different requirements. To ensure that these HB BLE devices comply with these regional requirements, their channel access mechanism will differ from that of traditional BLE devices operating in the 2.4GHz band. For example, HB BLE devices use FB-LBT (Frame-Based Listen Before Talk) for channel access.

[0003] However, since the 5GHz / 6GHz band is an unlicensed spectrum, other wireless technologies, such as Wi-Fi devices, can use these bands provided they meet the relevant regulatory requirements. Typically, Wi-Fi devices currently operating on the 5GHz / 6GHz band generally use relatively high bandwidths, such as BW 80MHz or BW 160MHz. This high bandwidth makes it easier for HB BLE devices to have their operating channel fall within the Wi-Fi operating bandwidth at any given time, causing narrowband interference to the Wi-Fi receiver. Summary of the Invention

[0004] This invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one object of this invention is to provide a wireless communication method that can effectively solve the narrowband interference problem of HB BLE devices on wireless devices.

[0005] The second objective of this invention is to provide a wireless device.

[0006] The third objective of this invention is to provide a computer storage medium.

[0007] To address the aforementioned problems, a first aspect of the present invention provides a wireless communication method, comprising: generating a Protocol Data Unit (PPDU); and performing frequency domain resource copying on the PPDU in units of Resource Units (RUs) to obtain a final Protocol Data Unit (PPDU).

[0008] According to the wireless communication method of the present invention, frequency domain resource copying is performed on Protocol Data Units (PPDUs) in units of Resource Units (RUs). The same data is carried by multiple Resource Units (RUs). Even if any Resource Unit (RU) is subject to narrowband interference, the receiver can still receive the data completely through other Resource Units (RUs).

[0009] In some embodiments, the Protocol Data Unit (PPDU) includes at least a data field, and copying the PPDU in the frequency domain at the level of Resource Units (RUs) includes copying the data field in the frequency domain at the level of Resource Units (RUs).

[0010] In some embodiments, the resource unit RU includes a resource unit RU with size information of 106, a resource unit RU with size information of 242, and / or a resource unit RU with size information of 484.

[0011] In some embodiments, when the Protocol Data Unit (PPDU) is copied in frequency domain by resource unit (RU), the data copied in each resource unit (RU) is the same.

[0012] In some embodiments, for a wireless device, the wireless device is allocated a plurality of resource units (RUs), and when copying the protocol data unit (PPDU) in the frequency domain by resource unit (RU), the method includes: grouping the plurality of resource units (RUs); and in each group, the data copied in each resource unit (RU) is the same.

[0013] In some embodiments, each resource unit RU in each group is continuous in the frequency domain.

[0014] In some embodiments, each resource unit RU in each group is discontinuous in the frequency domain.

[0015] In some embodiments, grouping multiple resource units RU includes: grouping multiple resource units RU according to the size information of the resource unit RU.

[0016] In some embodiments, for a wireless device, the data domain includes N data segments, each data segment occupies a bandwidth equal to the operating bandwidth of the wireless device, and the protocol data unit (PPDU) is copied in frequency domain resources in units of resource units (RU), including: copying M data segments in the protocol data unit (PPDU) in frequency domain resources in units of resource units (RU), where 1 ≤ M ≤ N.

[0017] In some embodiments, when 1 < M, the size information of the resource unit RU used by different data segments may be the same or different.

[0018] In some embodiments, when the M data segments in the Protocol Data Unit (PPDU) are copied in the frequency domain using resource units (RU), the frequency domain resource copying is performed within a single data segment using resource units (RU) with at least one size information.

[0019] In some embodiments, the Protocol Data Unit (PPDU) includes header punching information. Before copying the PPDU in frequency domain resources in units of Resource Units (RUs), the method further includes: determining the usable size information of the Resource Units (RUs) based on the header punching information.

[0020] In some embodiments, the bandwidth occupied by the Protocol Data Unit (PPDU) is greater than or equal to BW80 MHz.

[0021] A second aspect of the present invention provides a wireless device, including at least one processor; a memory communicatively connected to at least one of the processors; wherein the memory stores a computer program executable by at least one of the processors, and the at least one processor executes the computer program to implement the wireless communication method of the above embodiments.

[0022] According to the wireless device of the present invention, the wireless communication method of the above embodiments is implemented by the processor executing a computer program, which can effectively solve the narrowband interference caused by HB BLE devices to the Wi-Fi receiver.

[0023] A third aspect of the present invention provides a computer storage medium having a computer program stored thereon, wherein the computer program, when executed by a processor, implements the wireless communication method of the above embodiments.

[0024] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0027] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0028] The current traditional 802.11 non-HT (non-high throughput) DUP PPDU format allows duplication in the frequency domain resources in units of bandwidth 20 MHz (BW20 MHz). For example... Figure 1 As shown, for Wi-Fi device 1, there are HB BLE devices nearby. Because these BLE devices cannot detect the data transmitted by Wi-Fi device 2, the BLE devices can also perform BLE data interaction while Wi-Fi device 2 is transmitting, which will cause narrowband interference to Wi-Fi device 1. Figure 2The image shows a BW80 802.11 non-HT DUP PPDU, which is a copy of four BW20 non-HT PPDUs in terms of frequency domain resources. Under this non-HT DUP PPDU, the physical layer modulation / coding / space used by the copied part must still be the same as the traditional non-HT format, that is, the capability is limited. In 802.11be, an 802.11be EHT (Extreme High Throughput) DUP PPDU format is defined. In this EHT DUP PPDU, under the limitation of physical layer modulation / coding / space stream, the copying rules of its frequency domain resources are as follows: BW80 EHT DUP PPDU, copying unit is 484-tone RU; BW160 EHT DUP PPDU, copying unit is 996-tone RU; BW320 EHT DUP PPDU, copying unit is 2x996-tone RU. Under the limitation of EHT, there are only three copying rules.

[0029] To address the aforementioned problems, a first aspect of this invention proposes a wireless communication method that can effectively solve the narrowband interference problem of HB BLE devices on wireless devices.

[0030] The following is for reference. Figure 3 A wireless communication method according to an embodiment of the present invention is described, such as... Figure 3 As shown, the method includes steps S1-S2, and the specific steps are as follows.

[0031] Step S1: Generate Protocol Data Unit (PPDU).

[0032] Specifically, before data transmission, the data to be transmitted is encapsulated into a PPDU, i.e., a Protocol Data Unit (PPDU) is generated.

[0033] Step S2: The protocol data unit (PPDU) is copied in the frequency domain by means of resource units (RU) to obtain the final protocol data unit (PPDU).

[0034] In related technologies, the current traditional 802.11 non-HT (non-high throughput) DUP PPDU format allows replication of frequency domain resources in units of fixed bandwidth. Alternatively, 802.11be defines an 802.11be EHT (Extreme High Throughput) DUP PPDU format. In this EHT DUP PPDU, the replication rules for frequency domain resources are: the replication unit for BW80 is 484-tone RU; for BW160, it is 996-tone RU; and for BW320, it is 2x996-tone RU. However, the capabilities for physical layer modulation / coding / spatial streaming are limited in these methods.

[0035] Specifically, to address the aforementioned issues, this application first generates original Protocol Data Units (PPDUs). Then, it performs frequency-domain resource copying on the original PPDUs at the Resource Unit (RU) level. This results in the final PPDU obtained after copying, namely the 802.11 DUP PPDU, which can carry the same data across different frequency bands. Therefore, even if any Resource Unit (RU) is subject to narrowband interference, the receiver can still receive data completely through other Resource Units (RUs). Furthermore, the copying rules based on frequency-domain resource copying at the Resource Unit (RU) level allow the 802.11 DUP PPDU to use any physical layer modulation / coding / spatial stream permitted under non-DUP PPDUs. Additionally, the 802.11 DUP PPDU can be applied to downlink transmission from AP to STA, and / or uplink transmission from STA to AP; or to single-user (SU) PPDU transmission and / or multi-user (MU) PPDU transmission between AP and STA.

[0036] According to the wireless communication method of the present invention, frequency domain resource copying is performed on Protocol Data Units (PPDUs) in units of Resource Units (RUs). The same data is carried by multiple Resource Units (RUs). Even if any Resource Unit (RU) is subject to narrowband interference, the receiver can still receive the data completely through other Resource Units (RUs).

[0037] In some embodiments, the Protocol Data Unit (PPDU) includes at least a data field, and frequency domain resource copying of the PPDU at the level of Resource Units (RUs) includes frequency domain resource copying of the data field at the level of Resource Units (RUs).

[0038] Specifically, the frequency domain resource copying can be limited to the data field of the PPDU. Other fields and the PPDU PHY Header remain consistent with the current 802.11 protocol. The indication of the mode for frequency domain resource copying of the data field at the resource unit (RU) level is carried by relevant information bits in the PHY Header of the final protocol data unit (PPDU), i.e., the 802.11 DUP PPDU. Since frequency domain resource copying is not performed in the 802.11 DUP PPDU PHY Header, the receiving end can receive the 802.11 DUP PPDU PHY Header normally in the traditional manner. Furthermore, by parsing the relevant information fields in the PHY Header, the receiving end can obtain information about the mode of frequency domain resource copying of the data field at the resource unit (RU) level, and thus parse subsequent data fields based on this information.

[0039] In some embodiments, the resource unit RU includes a resource unit RU with size information of 106, namely a 106-tone RU, a resource unit RU with size information of 242, namely a 242-tone RU, and / or a resource unit RU with size information of 484, namely a 484-tone RU.

[0040] Specifically, the size information is used to represent the bandwidth occupied by a single resource unit (RU), represented by the number of subcarriers contained in the RU. The smallest RU unit for frequency domain resource replication can have its size information limited to 10⁶-tone RU; or 10⁶-tone RU and / or 242-tone RU; or 10⁶-tone RU and / or 242-tone RU and / or 484-tone RU, where, for example... Figure 4 As shown, there are three BW80 DUP PPDUs. Figure 4 (a) The PPDU performs resource replication using a 106-tone RU as the smallest RU unit. Figure 4 (b) uses a 242-tone RU as the smallest RU unit for resource replication in the PPDU. Figure 4 (c) The PPDU performs resource replication with a 484-tone RU as the smallest RU unit.

[0041] In some embodiments, when the Protocol Data Unit (PPDU) is copied in the frequency domain by resource unit (RU), the data copied in each resource unit (RU) is the same.

[0042] Specifically, such as Figure 5 As shown, there are three BW80 MHz DUP PPDUs. Figure 5In (a) of the DUP PPDU, all 106-tone RUs copy the same data, that is, the data of each DUP of RU1 is copied from the data of the 106-tone RU; Figure 5 In (b) the DUP PPDU, the data in DUP of RU1 is copied from the data of 106-tone RU1, the data in DUP of RU2 is copied from the data of 106-tone RU2, the data in DUP of RU3 is copied from the data of 106-tone RU3, and so on. Figure 5 The same replication principle applies to the DUP PPDU in (c).

[0043] In some embodiments, the above wireless communication method is used for a wireless device, which is allocated multiple resource units RU. When copying Protocol Data Units (PPDUs) in the frequency domain by resource unit RU, the method includes grouping the multiple resource units RU; in each group, the data copied in each resource unit RU is the same.

[0044] Specifically, such as Figure 5 As shown, there are three BW80 MHz DUP PPDUs. Figure 5 (b) and Figure 5 (c) divides all 106-tone RUs into four groups: 106-tone RU1, 106-tone RU2, 106-tone RU3, and 106-tone RU4. Within each group, the data replicated by each resource unit RU is identical; that is, 106-tone RU1 and its DUP of RU1 are identical, 106-tone RU2 and its DUP of RU2 are identical, 106-tone RU3 and its DUP of RU3 are identical, and 106-tone RU4 and its DUP of RU4 are identical. Multiple resource units RUs can be grouped according to size information or bandwidth requirements, etc., without specific restrictions here.

[0045] In some embodiments, each resource unit RU in each group is continuous in the frequency domain.

[0046] Specifically, such as Figure 5 As shown, Figure 5(b) All 106-tone RUs in the DUP PPDU are divided into 4 groups: 106-tone RU1, 106-tone RU2, 106-tone RU3 and 106-tone RU4. The data copied in each resource unit RU in each group is the same, and each resource unit RU in each group is continuous in the frequency domain. For example, 106-tone RU1 and DUP of RU1 are continuous.

[0047] In some embodiments, each resource unit RU in each group is discontinuous in the frequency domain.

[0048] Specifically, such as Figure 5 As shown, Figure 5 In (c) of the DUP PPDU, all 106-tone RUs are divided into 4 groups. The data copied in each resource unit RU in each group is the same, and each resource unit RU in each group is discontinuous in the frequency domain, separated by a fixed frequency domain range. For example, 106-tone RU3 and DUP of RU3 are discontinuous, separated by 106-tone RU4.

[0049] Each resource unit (RU) is separated by a fixed frequency range. This frequency range can be selected based on actual conditions; no specific limitation is imposed here. For example, such as... Figure 6 As shown, all 106-tone RUs are divided into 4 groups. The data replicated in each resource unit RU in each group is the same, and each resource unit RU in each group is discontinuous in the frequency domain. Among them, 106-tone RU3 and DUP of RU3 are discontinuous and separated by DUP of RU2, DUP of RU1 and 106-tone RU4.

[0050] In some embodiments, grouping multiple resource units (RUs) includes grouping multiple resource units (RUs) according to the size information of the resource units (RUs).

[0051] Specifically, multiple resource units (RUs) can be grouped according to the size information of the resource units (RUs). For example, the resource units (RUs) can be divided into 106-tone RU groups, 242-tone RU groups, and 484-tone RU groups.

[0052] In some embodiments, the above wireless communication method is used for a wireless device, the data domain includes N data segments, the bandwidth occupied by each data segment is the working bandwidth of the wireless device, and the protocol data unit PPDU is copied in frequency domain resources in units of resource units RU, including copying M data segments in the protocol data unit PPDU in units of resource units RU, where 1≤M≤N.

[0053] Specifically, each data segment of the Protocol Data Unit (PPDU) can be independently duplicated in the frequency domain of the Resource Unit (RU). Optionally, for an 802.11 DUP PPDU containing N data segments, only one data segment may be duplicated in the frequency domain of the Resource Unit (RU); or, two, three, more, or all data segments may be duplicated in the frequency domain of the Resource Unit (RU), and these multiple data segments do not need to be contiguous in the frequency domain. For example, if a Protocol Data Unit (PPDU) contains multiple data segments, these segments may not be contiguous in the frequency domain. Taking a PPDU containing four BW80 MHz data segments as an example, these four segments are BW80 Seg1, BW80 Seg2, BW80 Seg3, and BW80 Seg4, each occupying a bandwidth of BW80 MHz. Therefore, when performing frequency domain resource copying, it is possible to copy only any one of the BW80 MHz Seg1, BW80 MHz Seg2, BW80 MHz Seg3, and BW80 MHz Seg4, or to copy some or all of the data segments. For example, it is possible to copy BW80 MHz Seg1 and BW80 MHz Seg4. Seg4 is copied, while BW80 MHz Seg2 and BW80 MHz Seg3 are not copied. Among them, BW80 Seg1 and BW80Seg4 are discontinuous in the frequency domain.

[0054] For example, such as Figure 7 As shown in (a), the Protocol Data Unit (PPDU) contains two BW80 MHz data segments, of which only one data segment is frequency domain resource copied.

[0055] In some embodiments, when 1 < M, the size information of the resource unit RU used by different data segments may be the same or different.

[0056] For details, please refer to Figure 7 As shown in (b), taking a PPDU containing two BW80 MHz data segments as an example, both BW80 MHz data segments are copied in the frequency domain using 106-tone RUs as the unit, meaning that the size information of the resource unit RUs used by the two different data segments is the same. (Referencing...) Figure 7As shown in (c), taking a PPDU containing two BW80MHz data segments as an example, one BW80 MHz segment (Seg1) selects to perform frequency domain resource copying in units of 106-tone RUs, while the other BW80 MHz segment (Seg2) selects to perform frequency domain resource copying in units of 242-tone RUs. The size information of the resource unit RUs used by the two different data segments is different. When performing frequency domain resource copying of multiple data segments in a protocol data unit (PPDU) in units of resource units RUs, 106-tone RUs and / or 242-tone RUs and / or 484-tone RUs can be selected for frequency domain resource copying; no specific restrictions are imposed here.

[0057] In some embodiments, when frequency domain resource copying is performed on M data segments in a Protocol Data Unit (PPDU) in units of resource units (RU), frequency domain resource copying is performed on a single data segment in units of resource units (RU) with at least one size information.

[0058] Specifically, when copying a data segment in a Protocol Data Unit (PPDU) in the frequency domain using Resource Units (RUs), a single data segment can be copied using only one RU of different sizes, such as a 106-tone RU, a 242-tone RU, or a 484-tone RU. Alternatively, a single data segment can be copied using multiple RUs of different sizes, meaning that a single data segment can be copied using some or all of the 106-tone RU, 242-tone RU, and 484-tone RUs. For example, some data in a single data segment can be copied using 106-tone RUs, and some data can be copied using 242-tone RUs.

[0059] In some embodiments, the Protocol Data Unit (PPDU) includes header puncture information. Before performing frequency domain resource copying of the PPDU in units of Resource Units (RUs), the method further includes determining usable size information of the Resource Units (RUs) based on the header puncture information.

[0060] Specifically, the preamble punch mode is a mode in the current 802.11 protocol. In the current 802.11 protocol, the presence of the preamble punch mode affects the selection of usable size information for resource elements (RUs). When the preamble punch mode is present, the range and combination of usable size information for resource elements (RUs) are significantly limited. Therefore, it is necessary to consider the usable size information under the preamble punch mode. The 802.11 DUP PPDU format copied in this application can be used in conjunction with the preamble punch mode defined in the current 802.11 protocol, and the usable size information for frequency domain resource copying of each data segment of the 802.11 DUP PPDU must be selected according to the current frequency band. For example, with a PPDU bandwidth of BW80 MHz, when only one BW20 MHz is punctured, the usable size information for the replication of frequency domain resources can be selected as 106-tone RU and / or 242-tone RU; when two BW20 MHz are punctured, the usable size information for the replication of frequency domain resources can be selected as 106-tone RU and / or 242-tone RU; and when three BW20 MHz are punctured, the usable size information for the replication of frequency domain resources can be selected as 106-tone RU.

[0061] For example, such as Figure 8 As shown, Figure 8 This is a schematic diagram of two BW80 MHz 802.11 DUPPPDUs with header punch-hole patterns. The resource units (RUs) are not grouped. Figure 8 (a) One BW20 MHz, Figure 8 In (b), two BW20 MHz circuits are punched, such as... Figure 9 As shown, Figure 9 This is a schematic diagram of a BW80 MHz 802.11 DUP PPDU with a header punch pattern. The resource unit RU uses 106-tone RUs as the unit group, and only two 106-tone RUs are reserved for use to accommodate the header punch pattern.

[0062] In some embodiments, the bandwidth occupied by the Protocol Data Unit (PPDU) is greater than or equal to BW80 MHz.

[0063] In some embodiments, the method of this application can be applied to: a) downlink transmission from AP device to STA device, and / or uplink transmission from STA device to AP device; b) single-user (SU) PPDU transmission between AP device and STA device, and / or multi-user (MU) PPDU transmission.

[0064] A second aspect of the present invention provides a wireless device 10, such as... Figure 10 As shown, the wireless device 10 includes at least one processor 1 and at least one memory 2 communicatively connected to the processor 1.

[0065] The memory 2 stores a computer program that can be executed by at least one processor 1. When the at least one processor 1 executes the computer program, it implements the wireless communication method of the above embodiment.

[0066] According to the wireless device 10 of the present invention, the wireless communication method of the above embodiment is implemented by the processor executing a computer program, which can effectively solve the narrowband interference problem caused by the HB BLE device to the Wi-Fi receiver.
