[0163] In some embodiments, the AP can be an access point for a mobile terminal to enter a wired network. The AP is equivalent to a bridge connecting the wired network and the wireless network, and its main function is to connect various wireless network clients together and then access the Ethernet network. Specifically, the AP can be a terminal device or a network device with a wireless fidelity (Wi-Fi) chip. Optionally, the AP can support multiple WLAN standards such as 802.11ax, 802.11be, 802.11ac, 802.11n, 802.11g, 802.11b, 802.11a, 802.11bf, 802.11bn, and the next generation 802.11 protocol, but is not limited thereto.

[0166] It can be understood that the communication system described in the embodiments of the present disclosure is for more clearly illustrating the technical solutions of the embodiments of the present disclosure, and does not constitute a limitation on the technical solutions proposed by the embodiments of the present disclosure. Those skilled in the art can know that, with the evolution of system architecture and the appearance of new business scenarios, the technical solutions proposed by the embodiments of the present disclosure are also applicable to similar technical problems.

[0167] The embodiments of the present disclosure described below can be applied to the communication system 100 shown in FIG. 1 or part of the subject, but are not limited thereto. The subjects shown in FIG. 1 are examples, and the communication system can include all or part of the subjects in FIG. 1, or other subjects other than those in FIG. 1. The number and form of each subject is arbitrary, each subject can be real or virtual, the connection relationship between each subject is an example, each subject can not be connected or can be connected, and the connection can be in any way, can be direct connection or indirect connection, can be wired connection or wireless connection.

[0168] The embodiments of the present disclosure can be applied to a wireless local area network (WLAN), such as a local area network using 802.11 series protocols. In a WLAN, a basic service set (BSS) is a basic component of a WLAN. A BSS network is composed of station devices having some association within a certain coverage area. One situation of association is that stations directly communicate with each other in an ad hoc network, which is called an independent BSS (IBSS). Another more common situation is that there is only one central station with a full-time management BSS in the BSS network, which is called an access point device, and other stations in the BSS network that are not APs are called terminals, also called non-AP STAs, APs and non-AP STAs are collectively called STAs. When describing STAs, it is not necessary to distinguish between APs and non-AP STAs. In the same BSS network, due to distance, transmission power, etc., one STA cannot detect other STAs far away from it, and the two are each other's hidden nodes.

[0169] FIG. 2 is an interaction diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG. 2, the above method includes:

[0170] In step 201, the first device 101 determines a first PPDU (Physical Layer Protocol Data Unit); wherein the first PPDU comprises first identification information, the first identification information being used to identify a transmission rate of a data part of the first PPDU; and the transmission rate comprises 1.5 Mbps (megabits per second) or 3 Mbps.

[0171] In actual communication, due to different power amplifier (PA) modes of communication devices, the transmission power of the communication devices is quite different, which causes a large difference in link margin between uplink and downlink formed between the communication devices. For example, in the case that the communication devices include an AP and a STA, due to different PA modes of the AP and the STA, the transmission power of the AP and the transmission power of the STA can be at least 2 times (6 dB) different, which causes a large difference in link margin between uplink and downlink formed between the communication devices. Therefore, it is necessary to further improve the current transmission mechanism to balance the difference in link margin between uplink and downlink formed between the communication devices.

[0172] To this end, in the embodiment of the present disclosure, the first device 101 limits the transmission rate of the data part of the first PPDU by the content carried by the first identification information in the first PPDU, and specifically limits the transmission rate of the data part of the first PPDU to 1.5 Mbps or 3 Mbps, that is, limits the first device 101 and the device receiving the first PPDU to transmit the data part of the first PPDU at a lower transmission rate, which can balance the difference in link margin between uplink and downlink formed between the communication devices as much as possible, and avoid the problem that the difference in link margin between uplink and downlink formed between the communication devices is too large due to a high data transmission rate.

[0173] Optionally, in the embodiment of the present disclosure, the data carried in the first PPDU, that is, the data part of the first PPDU, can also be referred to as the load part of the first PPDU, and the present disclosure does not limit the name. In the embodiment of the present disclosure, the data part of the first PPDU is taken as an example for description.

[0174] Optionally, the communication method provided by the embodiment of the present disclosure can be applied in a long-distance communication process. In the case that the communication method is applied in the long-distance communication process, the first PPDU can also be referred to as an ELR (Enhanced Long Range) PPDU.

[0175] Optionally, in the embodiments of the present disclosure, when the transmission rate of the data part of the first PPDU is 1.5 Mbps or 3 Mbps, the transmission bandwidth corresponding to the first PPDU is 20 MHz.

[0176] In the embodiments of the present disclosure, in the first PPDU, the transmission rate of the data part of the first PPDU can be identified by one identification bit (i.e., the first identification bit), or can be identified by two identification bits (i.e., the second identification bit and the third identification bit).

[0177] Optionally, in the embodiments of the present disclosure, the first identification information includes the first identification bit, and / or the first identification information includes the second identification bit and the third identification bit; wherein,

[0178] When the first identification information includes the first identification bit, the first identification bit is used to identify whether the transmission rate is 1.5 Mbps or 3 Mbps.

[0179] When the first identification information includes the second identification bit and the third identification bit, the second identification bit is used to identify whether the transmission rate is 1.5 Mbps, and the third identification bit is used to identify whether the transmission rate is 3 Mbps.

[0180] Optionally, when the first identification information includes the first identification bit, different transmission rates can be identified by setting the first identification bit to different parameter values.

[0181] As an example, assuming that the first identification bit includes one bit, when the first identification bit is set to a third value (for example, the third value can be "0"), the first identification bit is used to identify that the transmission rate of the data part of the first PPDU is 1.5 Mbps. When the first identification bit is set to a fourth value (for example, the third value can be "1"), the first identification bit is used to identify that the transmission rate of the data part of the first PPDU is 3 Mbps.

[0182] Optionally, when the first identification information includes the second identification bit and the third identification bit, different identification bits can be corresponded to different transmission rates, when the identification bit is set to a fifth value (for example, in the case that the identification bit includes one bit, the fifth value can be "1"), the identification bit can be used to identify that the transmission rate of the data part of the first PPDU is the transmission rate corresponding to the identification bit; when the identification bit is set to a sixth value (for example, in the case that the identification bit includes one bit, the sixth value can be "0"), the identification bit can be used to identify that the transmission rate of the data part of the first PPDU is not the transmission rate corresponding to the identification bit.

[0183] It can be understood that the second identification bit and the third identification bit cannot be set to the fifth value at the same time.

[0184] As an example, assuming that the second identification bit includes one bit, and the second identification bit corresponds to 1.5 Mbps, and the third identification bit includes one bit, and the third identification bit corresponds to 3 Mbps, in the case that the second identification bit is set to 1, and the third identification bit is set to 0, the first identification information is used to identify that the transmission rate of the data part of the first PPDU is 1.5 Mbps, and is not 3 Mbps.

[0185] Optionally, in the case that the transmission rate of the data part of the first PPDU can also be set to other parameter values, the number of bits of the first identification bit can also be correspondingly set, and the correspondence between the parameter values set by the first identification bit and the transmission rate values; or, the identification bit corresponding to the transmission rate can also be appropriately increased, so as to identify, based on the value of the bit, whether the transmission rate of the data part of the first PPDU is the transmission rate corresponding to the bit.

[0186] Optionally, in the embodiments of the present disclosure, the first identification information can be carried in the preamble field of the first PPDU. Specifically, the preamble field of the first PPDU includes a UHR-SIG (UHR: Ultra High Reliability; SIG: signal) domain, the UHR-SIG domain includes an MCS (Modulation and Coding Scheme), and the first identification information is carried in the MCS identification bit.

[0187] Optionally, the MCS information supported by the device is associated with a plurality of communication parameters, for example, the communication parameters associated with the MCS information can include but are not limited to at least one of the following: NSS (Number of Spatial Streams), modulation mode supported by each spatial stream, coding rate, BW (bandwidth), transmission resource type supported by the device (for example, RU (Resource Unit), MRU (Multiple Resource Unit), dRU (distributed Resource Unit), UEQM, etc.), whether the device supports a punctured pattern of BW, and punctured channel density supported by the device. And in the case that the first device 101 supports UEQM (unequal modulation), that is, the modulation modes in different spatial streams supported by the first device 101 are different.

[0188] Optionally, in one spatial stream supported by the device, the supported modulation mode can include one of Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK), 16-Quadrature Amplitude Modulation (QAM), 64-QAM, 256-QAM, 1024-QAM, 4096-QAM, etc. Optionally, in one spatial stream supported by the device, the supported coding rate of the device can be 1 / 2, 2 / 3, 3 / 4, 5 / 6. Optionally, the supported BW of the device can be at least one of 20MHz, 40MHz, 80MHz, 160MHz, and 320MHz. Optionally, when the device supports the BW punctured channel mode, the supported punctured channel density of the device can be at least one of 20MHz, 40MHz, 80MHz, 160MHz, and 320MHz.

[0189] For one device, the supported MCS information of the device can refer to Table 1.

[0190] Table 1

[0191] As shown in Table 1, in Table 1, n, n+1, n+2, n+3, n+4, etc. are only examples and are used to identify the difference between each row. The specific values need to be adjusted according to the actual situation. In each row, the corresponding NSS, modulation, coding rate, transmission resource type, BW, whether to support puncturing, and punctured channel density of the device can be combined at will, and the corresponding MCS index value is different under different combinations. For example, in the first row, the MCS index value corresponding to different combinations can be t, t+1, t+2, etc.

[0192] Referring to the above, in the case that the first device 101 supports UEQM, the modulation mode of the first device 101 in different spatial streams supported by the first device 101 is different, and the transmission rate of the data part of the first PPDU in each spatial stream can be associated with the modulation mode of the data part of the first PPDU in the spatial stream. In view of this, the embodiments of the present disclosure further provide the following optional implementation manner:

[0193] Optionally, in some embodiments, in the case that the first device 101 supports UEQM, the UHR-SIG field includes: MCS identification bits corresponding to each spatial stream supported by the first device 101.

[0194] The first identification information carried by the MCS identification bit is used to identify a transmission rate of the data part of the first PPDU in the spatial stream corresponding to the MCS identification bit.

[0195] Optionally, in the case that the device supports UEQM (unequal modulation), the MCS identification information bits with the same number of bits as the NSS supported by the device can be set to identify different modulation modes in different spatial streams based on the NSS supported by the device.

[0196] As an example, taking the case that the NSS supported by the first device 101 is 2 and the first device 101 supports UEQM as an example, it is assumed that the modulation mode of the first device 101 in one of the spatial streams is BPSK and the modulation mode of the first device 101 in another spatial stream is QPSK, then: in the preamble field of the first PPDU, specifically in the UHR-SIG field of the preamble field, the MCS identification bits corresponding to each spatial stream are included to identify the transmission rate of the data part of the first PPDU in the spatial stream corresponding to the MCS identification bit.

[0197] In the above embodiment, in the case that the first device 101 supports UEQM, the MCS identification bits corresponding to each spatial stream can be set in the UHR-SIG field, and the first identification information carried by each MCS identification bit is used to identify the transmission rate of the data part of the first PPDU in the spatial stream corresponding to the MCS identification bit; in this way, in each spatial stream, the transmission rate of the data part of the first PPDU can be adapted to the modulation mode for the data part of the first PPDU.

[0198] In the embodiments of the present disclosure, in the first PPDU, different identification information is used to identify specific information of the first PPDU (transmission direction, type of transmission protocol adopted, transmission duration information, etc.) and specific information of the first device 101 (type of transmission resource unit supported by the first device 101 under a 20MHz bandwidth, identification information of the BSS in which the first device 101 is located, NSS supported by the first device 101, etc.); in this way, the device receiving the first PPDU can obtain the specific information of the first PPDU and the specific information of the first device 101 based on the information carried by the first PPDU, so as to successfully transmit the data carried by the first PPDU while avoiding interference to other communication processes in the process of transmitting the PPDU by the first device 101.

[0199] Optionally, in the embodiments of the present disclosure, the first PPDU further includes at least one of second identification information, third identification information, fourth identification information, fifth identification information, sixth identification information, and seventh identification information; wherein,

[0200] The second identification information is used for identifying the transmission direction of the first PPDU.

[0201] The third identification information is used for identifying the transmission protocol type adopted by the first PPDU.

[0202] The fourth identification information is used for identifying the type of the transmission resource unit supported by the first device 101 in a 20 MHz (Mega-hertz) bandwidth.

[0203] The fifth identification information is used for identifying the identification information of the BSS in which the first device 101 is located.

[0204] The sixth identification information is used for identifying the NSS (Number of Spatial Streams) supported by the first device 101; the NSS includes 1 or 2.

[0205] The seventh identification information is used for identifying the transmission duration information of the first PPDU.

[0206] Optionally, the transmission direction of the first PPDU can include uplink or downlink.

[0207] Optionally, in the case where the second identification information is included in the first PPDU, the UL (uplink) / DL (downlink) identification bit can also be included in the preamble field of the first PPDU, specifically in the UHR-SIG domain of the preamble field, and the second identification information is carried in the UL / DL identification bit.

[0208] Optionally, in the embodiments of the present disclosure, the transmission direction of the first PPDU can be determined based on the working frequency band of the first device 101, and then the transmission direction of the first PPDU is identified through the second identification information in the first PPDU.

[0209] Optionally, in the embodiments of the present disclosure, in the case where the first device 101 works in the 2.4 GHz (Giga-hertz) frequency band, the second identification information is used for identifying that the transmission direction of the first PPDU is uplink.

[0210] Or,

[0211] In the case where the first device 101 works in the 5 GHz frequency band or the 6 GHz frequency band, the second identification information is used for identifying that the transmission direction of the first PPDU is uplink or downlink.

[0212] Optionally, the transmission direction of the first PPDU can be indicated reversely according to the identification bit carried in the second identification information. For example, in the first PPDU, the transmission direction of the first PPDU can be indicated by one identification bit (i.e., the fourth identification bit), or the transmission direction of the first PPDU can be indicated by two identification bits (i.e., the fifth identification bit and the sixth identification bit).

[0213] Optionally, in the embodiments of the present disclosure, the second identification information includes a fourth identification bit, and / or the second identification information includes a fifth identification bit and a sixth identification bit; wherein,

[0214] In the case that the second identification information includes the fourth identification bit, the fourth identification bit is used to identify whether the transmission direction of the first PPDU is uplink or downlink.

[0215] In the case that the second identification information includes the fifth identification bit and the sixth identification bit, the fifth identification bit is used to identify whether the transmission direction of the first PPDU is uplink, and the sixth identification bit is used to identify whether the transmission direction of the first PPDU is downlink.

[0216] Optionally, in the case that the second identification information includes the fourth identification bit, the transmission direction of the first PPDU can be identified by setting the fourth identification bit to different parameter values.

[0217] As an example, assuming that the fourth identification bit includes one bit, in the case that the fourth identification bit is set to a seventh value (for example, the seventh value can be "0"), the fourth identification bit is used to identify that the transmission direction of the first PPDU is uplink. In the case that the fourth identification bit is set to an eighth value (for example, the seventh value can be "1"), the fourth identification bit is used to identify that the transmission direction of the first PPDU is downlink.

[0218] Optionally, in the case that the second identification information includes the fifth identification bit and the sixth identification bit, different identification bits can be corresponded to different transmission directions, in the case that the identification bit is set to a ninth value (for example, in the case that the identification bit includes one bit, the ninth value can be "1"), the identification bit can be used to identify that the transmission direction of the first PPDU is the transmission direction corresponding to the identification bit; in the case that the identification bit is set to a tenth value (for example, in the case that the identification bit includes one bit, the tenth value can be "0"), the identification bit can be used to identify that the transmission direction of the first PPDU is not the transmission direction corresponding to the identification bit.

[0219] It can be understood that the fifth identification bit and the sixth identification bit cannot be set to the ninth value at the same time.

[0220] As an example, assuming that the fifth identification bit includes one bit, and the fifth identification bit corresponds to uplink, the sixth identification bit includes one bit, and the sixth identification bit corresponds to downlink, in the case that the fifth identification bit is set to 1 and the sixth identification bit is set to 0, the second identification information is used to identify that the transmission direction of the first PPDU is uplink, and is not downlink.

[0221] Optionally, the transmission protocol type adopted by the first PPDU can include, but is not limited to, an UHR (Ultra High Reliability) protocol, an EHT (Extreme High Throughput) protocol, and the like.

[0222] Optionally, in the case that the third identification information is included in the first PPDU, in the preamble field of the first PPDU, specifically in the UHR-SIG field of the preamble field, a PHY version (Physical Interface Transceiver version) identification bit can also be included, and the third identification information is carried in the PHY version identification bit.

[0223] Optionally, the transmission resource type supported by the first device 101 under the 20MHz bandwidth can include the entire bandwidth (that is, a 242-tone RU (tone is a subcarrier; resource unit)) or a partial bandwidth (for example, a 106-tone dRU (dRU is a distributed resource unit)).

[0224] Optionally, in the case that the fourth identification information is included in the first PPDU, in the preamble field of the first PPDU, specifically in the UHR-SIG field of the preamble field, a BW (bandwidth) identification bit can also be included, and the fourth identification information is carried in the BW identification bit.

[0225] Optionally, in the case that the fourth identification information is included in the first PPDU, in the preamble field of the first PPDU, specifically in the UHR-SIG field of the preamble field, a BW (bandwidth) identification bit can also be included, and the fourth identification information is carried in the BW identification bit.

[0226] The fourth identification information is set to a first value, and the fourth identification information is used to identify that the first device 101 supports a 242-tone RU (tone is a subcarrier; resource unit) under a 20MHz bandwidth.

[0227] Or,

[0228] The fourth identification information is set to the second value, and the fourth identification information is used to identify that the first device 101 supports 106-tone dRU (dRU means distributed resource unit) under a 20MHz bandwidth.

[0229] Optionally, the specific values of the first value and the second value can be set according to actual conditions, and the embodiments of the present disclosure do not limit this. For example, the BW identification bit can include one bit, and the first value can be set to "0" and the second value can be set to "1".

[0230] As an example, when the BW identification bit is set to "0", the BW identification bit is used to identify that the first device 101 supports 242-tone RU under a 20MHz bandwidth; and when the BW identification bit is set to "1", the BW identification bit is used to identify that the first device 101 supports 106-tone dRU under a 20MHz bandwidth.

[0231] It can be understood that the corresponding relationship between the parameter value set by the fourth identification information and the number of subcarriers supported by the first device 101 under a 20MHz bandwidth can be adjusted according to actual conditions, for example, the fourth identification information can be set to the second value, and the fourth identification information is used to identify that the first device 101 supports 242-tone RU under a 20MHz bandwidth; or the fourth identification information is set to the first value, and the fourth identification information is used to identify that the first device 101 supports 106-tone dRU under a 20MHz bandwidth.

[0232] In the above embodiment, the transmission protocol type used by the first PPDU can be indicated by setting the fourth identification information to different parameter values.

[0233] Optionally, the identification information of the BSS in which the first device 101 is located can include but is not limited to the identification (BSSID, Basic Service Set Identification) of the BSS in which the first device 101 is located, the BSS color (Basic Service Set color) of the BSS in which the first device 101 is located, and the like.

[0234] Optionally, referring to the above, the first PPDU can be applied in a long-distance communication process (that is, support long-distance communication), and the transmission rate of the data part of the first PPDU is small (1.5Mbps or 3Mbps), in the embodiments of the present disclosure, the maximum NSS can be set to 2, that is, the NSS can be 1 or 2.

[0235] Optionally, the transmission duration information of the first PPDU can include a duration of transmitting the first PPDU, for example, a transmission opportunity (TXOP) obtained by the device transmitting the first PPDU.

[0236] Optionally, in the case where the seventh identification information is included in the first PPDU, in the preamble field of the first PPDU, specifically in the UHR-SIG field of the preamble field, a TXOP (transmission opportunity) information field can also be included, and the seventh identification information is carried in the TXOP information field.

[0237] Optionally, in some embodiments, in the case where the first device 101 supports different UEQMs, the transmission duration information of the first PPDU is the same.

[0238] In the above embodiment, in the case where the first device 101 supports transmitting the first PPDU by using different UEQMs, the transmission duration of the first PPDU is the same in different SSs; in other words, the transmission duration of the first PPDU is not affected by the UEQM supported by the first device.

[0239] In the above embodiment, in the first PPDU, the UHR-SIG field can also include at least one of an UL / DL identification bit, a PHY version identification bit, a BW identification bit, and a TXOP information field, and the identification information can be carried by different identification bits, to further carry specific information of the first PPDU (transmission direction, type of transmission protocol used, transmission duration information, etc.) and specific information of the first device 101 (type of transmission resource unit supported by the first device 101 under a 20 MHz bandwidth, etc.).

[0240] Step 202: The first device 101 sends a first PPDU to the second device 102. Correspondingly, the second device 102 receives the first PPDU sent by the first device 101.

[0241] In the embodiment of the present disclosure, the first device 101 determines and sends the first PPDU; the first identification information carried by the first PPDU identifies that the transmission rate of the data part of the first PPDU includes 1.5 Mbps or 3 Mbps; in this way, the data part of the first PPDU can be transmitted at 1.5 Mbps or 3 Mbps, so that in the process of long-distance data transmission, the link margin difference between the uplink and downlink formed between the communication devices can be balanced as much as possible, and the problem that the link margin difference between the uplink and downlink formed between the communication devices is too large due to a high data transmission rate can be avoided.

[0243] Step 301, the first device 101 determines a first wireless frame; wherein the first wireless frame includes eighth identification information, and the eighth identification information is used to identify support capability information of the first device 101 for transmitting the ELR PPDU.

[0244] Optionally, the support capability information of the first device 101 for transmitting the ELR PPDU can be determined based on a device type of the first device 101 and a frequency band in which the first device 101 operates, and is identified by the eighth identification information in the first wireless frame.

[0245] Optionally, in a case where the first device 101 is an AP or an AP MLD, the first wireless frame can include, but is not limited to, a beacon frame, a probe response frame, an association response frame, and a reassociation response frame.

[0246] Optionally, in a case where the first device 101 is a STA or a non-AP MLD, the first wireless frame can include, but is not limited to, a probe request frame, an association request frame, and a reassociation request frame.

[0247] Optionally, in a case where the first device 101 is an AP or an AP MLD and the first device 101 operates in a 5GHz frequency band or a 6GHz frequency band, the eighth identification information is used to identify that the first device 101 supports receiving an uplink ELR PPDU and supports transmitting a downlink ELR PPDU.

[0248] In a case where the first device 101 is a STA or a non-AP MLD and the first device 101 operates in a 2.4GHz frequency band, the eighth identification information is used to identify that the first device 101 supports transmitting an uplink ELR PPDU.

[0249] In a case where the first device 101 is a STA or a non-AP MLD and the first device 101 operates in a 5GHz frequency band or a 6GHz frequency band, the eighth identification information is used to identify that the first device 101 supports transmitting an uplink ELR PPDU and supports receiving a downlink ELR PPDU.

[0250] Step 302, the first device 101 sends the first wireless frame to the second device 102.

[0251] At step 303, the second device 102 determines a second wireless frame; wherein the second wireless frame comprises ninth identification information, the ninth identification information being used to identify the support capability information of the second device 102 for transmitting the ELR PPDU.

[0252] Optionally, the support capability information of the second device 102 for transmitting the ELR PPDU can be determined based on the device type of the second device 102 and the frequency band in which the second device 102 operates, and identified by the ninth identification information in the second wireless frame.
