Table 1
In the embodiment of the present application, so-called WUR, refer to equipment on the basis of configuring tradition WiFi interface (in following description referred to as 802.11 main modules (main radio) or principal communication interface), a LP WUR interface of introducing.
As shown in Fig. 1 (a) or Fig. 1 (b), for the structural schematic diagram of the equipment in the prior art including LP-WUR interface.In Fig. 1 (a) and Fig. 1 (b), website (Station,) and access point (Access Point STA, AP) other than transmitting data packet (Data Packet), the wake-up packet (Wake-up Packet, also known as wake-up association) carried by WUR PPDU can also be transmitted.802.11 main modules of website are generally in close pattern, and only when receiving from the wake-up signal of LP WUP, 802.11 main modules can just be activated, and then carry out data communication with access point (Access Point, AP).The LP WUP of website is continuously in reception state, or it is intermittent in reception state, when LP WUR receives wake-up packet (the Wake-up Packet from AP in reception state, also known as wake-up association) when, wake-up signal is sent to 802.11 main modules of website, to wake up 802.11 main modules being in close state.Wherein, the logically practical side AP also includes 802.11 main modules and WUR module, but for current 802.11 standard, 802.11 main modules are usually from orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing, OFDM) wideband transmitter, and WUR wake-up signal is narrow band signal, is simply considered for cost and structure is reduced, and can use OFDM wideband transmitter and generates narrowband WUR wake-up signal.Such as, it is the portion subcarriers of ofdm signal are vacant and signal is only transmitted on the corresponding narrowband of WUR wake-up signal, to generate narrow band signal, here it is the examples that WUR narrow band signal is generated using OFDM wideband transmitter, therefore the side AP only includes 802.11 main modules in Fig. 1 (a) and Fig. 1 (b).It should be strongly noted that 802.11 main modules and WUR module can also be realized respectively in the specific implementation of the side AP.In addition, AP and STA shows that an antenna in Fig. 1 (a) and Fig. 1 (b), this mainly consider 802.11 main modules and LP WUR module using similar frequency bands carrier wave (such as, in the case of 2.4GHz), the same antenna can be shared, to save cost and simplify device structure.But when 802.11 main modules and LP WUR module use different frequency range carrier wave, the two should configure different antennae.For example, 802.11 main modules use 5GHz frequency range, LP WUR module uses 2.4GHz frequency range, and the two should correspond to different antennae at this time.
Currently, STA, which receives signal using LP WUR, can reduce power consumption compared to using 802.11 main modules reception signal, main reason is that the reception and decoding of wake-up packet are simple more than traditional 802.11 frames.Wake-up packet generallys use the modulation system for being easy to receiving end demodulation, as OOK (on-off key, on-off keying) is modulated.By taking OOK is modulated as an example, receiving end passes through There is noenergy judgement to receive the information of signaling bearer, for example, having energy is 1, noenergy 0.And traditional 802.11 frames are since in transmitting terminal, using processing operations such as OFDM, BCC/LDPC, correspondingly, receiving end need to execute sophisticated signals processing operation, these operations such as FFT, FEC decoding and need to expend big energy.
In Fig. 1 (a) or Fig. 1 (b), 802.11 main modules of STA are also possible to other communication interfaces, such as LTE communication interface.For convenience, in the following contents, it will be used for the module of data communication, is referred to as principal communication module (main radio), i.e., 802.11 main modules, LTE communication module etc. is referred to as principal communication module;It will be used for the module of equipment wake-up, be referred to as WUR, i.e., will wake up radio-frequency module, wake-up radio frequency interface, LP WUR, WUR interface etc. and be referred to as WUR.
Currently, the specific design of the PPDU of wake-up packet a kind of is proposed in manuscript [11-16-0341-00-lrlp-low-power-wake-up-receiver-follow-up], as shown in Fig. 2 (a) and Fig. 2 (b).Wherein, Legacy practices sequence (Legacy Short Training Field, L-STF), traditional long training sequence (Legacy Long Training Field, L-LTF), traditional signaling message (Legacy Signal field, L-SIG) be tradition 802.11 the part legacy preamble (legacy preamble), it is sent in 20MHz (or integral multiple of 20MHz) bandwidth using OFDM mode, for backward compatibility, so that traditional WiFi equipment can judge current packet as WiFi packet, to select corresponding channel sense CCA decision threshold accordingly.If not considering backward compatibility, L-STF, L-LTF, L-SIG are possible to be not present.The load (WUR Payload) of wake-up packet is partially using the modulation system for being easy to demodulate, as OOK modulation is (specific such as ASK), it can be uploaded in more narrow bandwidth defeated, such as 2MHz channel, 4MHz channel, 5MHz channel etc. (traditional WiFi minimum bandwidth is 20MHz), so that the energy consumption of receiving end is smaller.WUR Payload includes waking up leading (Wake-up preamble) and the part MAC, STF, LTF and SIG in the former similar tradition WiFi, for synchronizing, AGC, channel estimation, controls information and indicates etc.;The part MAC of the similar traditional Wifi frame of the latter, it further comprise MAC header (Header), frame (Frame Body), Frame Check Sequence (FCS), the part MAC may carry out simple channel coding using modes such as duplication code, spreading code, Manchester codes, to improve reliability, but it is also possible to without using channel coding.Fairly simple due to waking up packet function, body section may also be not present.It include a string of particular sequences in Wake-up preamble, the WUR of STA does not receive the part Legacy preamble of front, but directly detects the particular sequence, to identify the beginning of wake-up packet.When the WUR of STA receives wake-up packet, and the mark (unicast/multicast/broadcast address) of oneself is detected from the part the MAC of wake-up packet, then send wake-up signal to 802.11 main modules.It is also possible that in Wake-up preamble and wakes up the domain signaling (Wakeup-Signal, WU-SIG), for carrying the length and used modulation coding scheme etc. of the part MAC.In addition to OOK, other modulation systems for being easy to demodulate, such as FSK are can also be used in the part WUR Payload.
Above-mentioned PPDU structure cannot be only used for wake-up packet, can be also used for it is other can be by the received frame of WUR, such as the synchronization frame synchronous for WUR.Using above-mentioned format, WUR PPDU can be referred to as by the received PPDU of WUR.
It should be noted that WUR, LP WUR and WUR interface are substantially identical terms in the embodiment of the present application, in order to unified, it is referred to as WUR below.
If the WUR of STA is chronically at state of activation, it is clear that power consumption can be compared.In a kind of possible implementation, the WUR intermittence of STA is active, and the time window that the WUR of STA is active is known as awake window (Wakeup window).The appearance of this awake window should be it is regular, so that AP is able to know that when the WUR of STA can receive wake-up packet.For example, WUR has 2ms to be active in every 100ms as shown in Fig. 3 (a) or Fig. 3 (b), i.e. the when a length of 2ms of awake window.When AP there are data to need to send to STA, wake-up packet can be sent in the awake window of the STA, to wake up 802.11 main modules of STA.It is of course also possible to not introduce awake window, i.e. the WUR of STA is in listening state always, this makes AP that can wake up STA at any time, advantageously reduces wake-up delay, the disadvantage is that STA energy consumption increases.
For the WUR PPDU structure as shown in Fig. 2 (a) or Fig. 2 (b), the bandwidth of legacy preamble is 20MHz, And the bandwidth of the part WUR payload is usually narrower, for example, 2MHz, 4MHz or 5MHz etc., it can more power saving when carrying out WUR detection so as to receiving end and receive WUR payload.Therefore, in terms of the frequency domain that WUR PPDU is occupied, shown in structure such as Fig. 4 (a) or Fig. 4 (b) of WUR PPDU shown in Fig. 2 (a) or Fig. 2 (b).
In Fig. 4 (a) or Fig. 4 (b), legacy preamble is actually the physical header of 802.11a standard (5GHz frequency range), it is simultaneously also the physical header of 802.11g standard (2.4GHz), duration is 20 μ s, its main function is backward compatibility, i.e. when a traditional WiFi equipment receives above-mentioned PPDU, it can determine that the PPDU is WiFi PPDU according to legacy preamble, certainly, when further solving part after legacy preamble check errors can occur for traditional WiFi equipment, finally abandon the PPDU.Why to allow other WiFi equipments to know that the PPDU is WiFi PPDU, be because being different in 802.11 standards for the CCA threshold value of WiFi PPDU and non-WiFi PPDU.For example, CCA threshold value is -82dBm if equipment detects WiFi PPDU, i.e., then think channel busy when the received signal strength that equipment receives the PPDU is higher than -82dBm, therefore no longer competitive channel, to avoid interfering the transmission of the PPDU as far as possible;If detecting non-WiFi signal, CCA threshold value is -62dBm, i.e., just thinks channel busy when the received signal strength that equipment receives the PPDU is higher than -62dBm.When receiving the intensity of non-WiFi signal between -82dBm and -62dBm, equipment will be considered that channel idle, to remove competitive channel and send.It obviously, is, so that third party's WiFi equipment be made not remove competitive channel and transmission as far as possible, the transmission to the part WUR payload to be avoided to interfere to allow third party's WiFi equipment to think that the PPDU is WiFi PPDU including legacy preamble in WUR PPDU.
For third party's WiFi equipment, such as traditional WiFi equipment or WUR are closed, the WUR equipment of main radio unlatching is (in the embodiment of the present application, WUR equipment refers to while being equipped with principal communication module and the equipment of WUR), when receiving above-mentioned PPDU, it will be considered that the PPDU is 802.11a PPDU, to go to the solution part WUR payload according to the structure of 802.11a PPDU, although finally being abandoned due to verification failure, this obviously will cause the additional power consumption of third party's WiFi equipment.
For target WUR equipment (in the embodiment of the present application, target WUR equipment is to need to receive the WUR equipment of wake-up packet), if its main radio is since other reasons are just at open state, then main radio also will be considered that the PPDU is 802.11a PPDU, and then the solution part WUR payload is gone to according to the structure of 802.11a PPDU, the PPDU is finally abandoned due to verification failure, this will cause wake-up end and calls out WUR equipment of not waking up.Therefore, to guarantee that a WUR equipment one is surely waken up, when its main radio is active, WUR must be also active simultaneously.As shown in figure 5, when WUR equipment receives a signal, main radio and WUR interface are always performed simultaneously detection, to determine whether the signal is that oneself being capable of received PPDU type.Obviously, this power consumption that will cause WUR equipment.A kind of possible scene that above situation occurs is as shown in Figure 6, mobile phone STA4 and wearable device STA1, STA2, STA3 configure WUR, certain moment, mobile phone STA4 was waken up by bracelet STA3, but AP is not aware that this thing, therefore when there is the downlink data of mobile phone STA4 on AP, also wake-up association can be sent to mobile phone STA4.If the WUR of mobile phone STA4 is closed at this time, the wake-up association can not be understood.From the point of view of AP angle, discovery mobile phone STA4 can not be waken up, and may execute the operation such as paging, to determine mobile phone STA4 whether also in the coverage area of oneself, this obviously will increase many unnecessary expenses.
In conclusion WUR PPDU structure shown in Fig. 2 (a) or Fig. 2 (b), is unfavorable for receiving third party's WiFi equipment of the WUR PPDU and target WUR equipment power saving.The embodiment of the present application in response to this problem, redesigns WUR PPDU structure, so that without going to the solution part WUR payload when traditional WiFi equipment receives WUR PPDU, to lower the power consumption of traditional WiFi equipment;It meanwhile when the main radio of WUR equipment receives WUR frame, can judge that further part is WUR payload, therefore WUR can be closed after main radio unlatching, thus more power saving.
The embodiment of the present application can be applied to WLAN (Wireless Local Area Network, WLAN), and WLAN accepted standard is 802.11 series of IEEE at present.WLAN may include one or more basic service sets, and the network node that basic service is concentrated includes AP and STA.Each basic service set may include an AP and multiple be associated with the AP STA.
AP, also referred to as access point or hot spot etc..AP is the access point that mobile subscriber enters cable network, and major deployments are inside family, inside buildings and garden, and typical covering radius is tens meters to rice up to a hundred, it is of course also possible to be deployed in open air.AP is equivalent to the bridge of connection a wired network and wireless network, and main function is to connect together each wireless network clients, then by wireless network access network based on ethernet.Specifically, AP can be terminal device or the network equipment with WiFi chip.Optionally, AP can support 802.11ax agreement, and still optionally further, which can be the equipment of a variety of WLAN protocols such as support 802.11ac, 802.11n, 802.11g, 802.11b and 802.11a.Usually, the equipment for supporting certain agreement, while being also compatible with the old agreement for working in same frequency range.For example, the 802.11n equipment for working in 2.4GHz frequency range is generally also compatible with 802.11b and 802.11g, the 802.11n equipment for working in 5GHz frequency range is generally also compatible with 802.11a.So-called certain agreement of equipment " compatibility ", i.e. equipment support the agreement.
STA can be wireless communications chips, wireless sensor or wireless communication terminal.Such as: the mobile phone for supporting WiFi communication function, the tablet computer for supporting WiFi communication function, the set-top box for supporting WiFi communication function, the smart television for supporting WiFi communication function, the intelligent wearable device for supporting WiFi communication function, the vehicular communication equipment for supporting WiFi communication function and the computer for supporting WiFi communication function.Optionally, website can support 802.11ax agreement, and still optionally further, which supports a variety of WLAN protocols such as 802.11ac, 802.11n, 802.11g, 802.11b and 802.11a.
Fig. 7 is the system schematic of a typical WLAN deployment scene.In Fig. 7, BSS1 and BSS2 are coexisted, wherein in BSS1 include AP1 and with AP1 associated STA1 to STA5;In BSS2 include AP2 and with AP2 associated STA6 to STA9.AP1 can send WUR PPDU to any one target STA for being configured with WUR in the associated STA of AP1.Due to the broadcast characteristic of wireless channel, the WUR PPDU also can other equipment associated by AP1 in addition to target STA and the equipment in neighbouring BSS receive, such as the equipment in BSS2.There may be the WUR equipment comprising being equipped with WUR in these equipment, it is also possible to there is traditional WiFi equipment comprising WUR is not configured.For traditional WiFi equipment, receives and parsing WUR PPDU is clearly to be not necessarily to, will cause additional reception power consumption.And for the WUR equipment for opening main radio, if can be determined according to the 20MHz physical header that main radio is received, the PPDU is WUR PPDU, then goes to open WUR interface further part, then can more power saving.More further, it can determine that current WUR PPDU is not intended for oneself according to the 20MHz physical header that main radio is received if opening the WUR equipment of main radio, thus do not parse further part, then it can further power saving.
In conjunction with the description of front, as shown in figure 8, being a kind of message processing method flow diagram provided by the embodiments of the present application.
In the process of Fig. 8, the first equipment can refer to that perhaps the second equipment of the equipment such as STA can refer to the equipment such as AP or STA to AP.
Referring to Fig. 8, this method comprises:
Step 801: the first equipment generates WUR PPDU, the WUR PPDU includes first part and second part, and the first part is located at before second part, and the first part meets the first standard agreement, the second part meets the second standard agreement, and second standard agreement is WUR standard;The first part includes legacy preamble and physics header field.
It wherein, include that WUR is indicated in the physics header field, the WUR instruction is used to indicate after the first part described in the WUR PPDU including the second part, and the WUR instruction is the predefined retention of the first subdomain in the physics header field.
Step 802: first equipment sends the WUR PPDU.
Step 803: the second equipment receives the WUR PPDU that the first equipment is sent, the WUR PPDU includes first part and second part, the first part is located at before second part, the first part meets the first standard agreement, the second part meets the second standard agreement, and second standard agreement is WUR standard;Before the first part includes traditional It leads and physics header field.
Step 804: if it includes that the second part receives and parses through the second part by WUR when second equipment meets preset condition that second equipment determines in the WUR PPDU according to WUR instruction;The preset condition includes: that second equipment includes WUR.
Correspondingly, if second equipment, when second equipment determination is unsatisfactory for the preset condition, is abandoned receiving the second part according to including the second part in the WUR instruction determination WUR PPDU.Such as, if the second equipment is the traditional WiFi equipment supported the first standard agreement but do not support the second standard agreement, second equipment is when the value for determining the first subdomain in physics header field is retention (i.e. the meaning that the second equipment can not understand the first subdomain), then determining itself can not parse the PPDU remainder, so as to abandon the reception to the PPDU remainder, to achieve the purpose that power saving.
In step 801 to step 804, the first part of WUR PPDU can also be known as physical header (Physical Layer Header, PHY Header) part, the second part of WUR PPDU can also be known as WUR payload, i.e. WUR PPDU can be made of PHY Header and WUP payload.Specific such as Fig. 9 (a) or Fig. 9 (b) is shown.
In Fig. 9 (a) or Fig. 9 (b), the part PHY Header may include legacy preamble and HT/VHT/HE (Header), it include that WUR is indicated in HT/VHT/HE Header, being used to indicate HT/VHT/HE Header includes later WUP payload.
Wherein, HT Header is the physics header field of 802.11n, can be supported 802.11n and the equipment of standard correctly parses later, such as 802.11n/ac/ax equipment;VHT Header is the physics header field of 11ac, can be supported 11ac and the equipment of standard correctly parses later, such as 802.11ac/ax equipment;HE Header is the physics header field of 802.11ax, can be supported 11ax and the equipment of standard correctly parses later, such as 802.11ax equipment.About the particular content of WUR payload, the related description of Fig. 2 (a) or Fig. 2 (b) and Fig. 2 (a) or Fig. 2 (b) can be referred to, details are not described herein.
In the embodiment of the present application, the part PHY Header can occupy 20MHz bandwidth, and WUR payload can occupy the bandwidth of the sizes such as 2MHz, 4MHz, 5MHz.
In the embodiment of the present application, WUR instruction should at least have one of following two aspects effects:
1) tradition WiFi equipment should be able to indicate that determining that the WUR PPDU including WUR instruction not be intended for the part oneself or in the WUR PPDU after HT/VHT/HE Header is not that oneself can parse according to WUR.This makes traditional WiFi equipment no longer go to the part after solution HT/VHT/HE Header, but the duration of part after HT/VHT/HE Header can be obtained according to the part legacy preamble, during this period, traditional WiFi equipment can enter dormant state, to achieve the purpose that power saving.
2) the main radio of WUR equipment can indicate to determine that HT/VHT/HE Header includes later WUR payload according to WUR, thus the part WUR payload for notifying WUR interface subsequent.This makes WUR equipment after main radio unlatching, and WUR may not necessarily detect signal (for example, close WUR or enter Doze state), to make the more power saving of WUR equipment.Doze state is also known as dormant state or (standby) state of awaiting orders, and refers to that equipment does not close reception circuit, but also do not detect and receive the state of signal;Closed state refers to that equipment closes the state for receiving circuit.
It should be noted that, the WiFi PPDU that the judgement of traditional WiFi equipment receives is any in HT/VHT/HE PPDU, is that (each general duration of symbol determines for the LENGTH field value in the domain L-SIG in 4 μ s) and Legacy preamble according to the several OFDM symbols followed closely after Legacy preamble.For example, determining the PPDU for HT PPDU if first symbol phase has rotated 90 degree (modulating using QBPSK) after LENGTH mod3=0 and Legacy preamble;If phase rotation (being modulated using BPSK) is not occurred for first symbol after LENGTH mod3=0 and Legacy preamble but second symbol phase has rotated 90 degree (modulating using QBPSK), Then determine the PPDU for VHT PPDU;If LENGTH mod3=1 or 2, determine the PPDU for HE PPDU.For HE PPDU, if the Format=1 in LENGTH mod3=1 and HE-SIG-A, determine the PPDU for HE SU PPDU;If 90 degree of second symbol of LENGTH mod3=2 and HE-SIG-A (i.e. third symbol after Legacy preamble) phase rotation (is modulated using QBPSK), then determine the PPDU for HE ER SU PPDU, wherein, mod is complementation.In all embodiments of the application, the setting and method of above-mentioned judgement PPDU type are not changed, i.e. equipment can still judge the PPDU type of the part PHY Header of WUR PPDU according to above-mentioned rule.The instruction that the embodiment of the present application newly increases, if WUR is indicated, included in HT/VHT/HE Header subdomain is carried.
The key of the embodiment of the present application is that WUR is indicated.The basic thought that WUR is indicated is carried in HT/VHT/HE Header is, it is indicated using the predefined retention of the first subdomain in HT/VHT/HE Header as WUR, such as, first subdomain, which can be reserved bit in HT/VHT/HE Header, or HT/VHT/HE Header still withs a hook at the end is worth not used subdomain.The so-called predefined retention using the first subdomain is indicated as WUR, is referred to and is selected specific one from the retention that the first subdomain remains, and is indicated as WUR.For example, the first subdomain is MCS subdomain, total 4bits, can the range of value be 0 to 15, standard has used therein 0 to 10 at present, and the retention of the subdomain is 11 to 15, selects specific one from these retentions, such as MCS=15, is defined as WUR and indicates.According to the difference of the PHY Header concrete type of WUR PPDU, the WUR PPDU in step 801 to step 804 can be described in detail separately below for convenience there are many implementation.
The first possible implementation: the first standard agreement is 802.11ax, and physics header field includes the domain RL-SIG and the domain HE-SIG-A, and first part meets HE SU PPDU format;First subdomain is MCS subdomain in the domain HE-SIG-A or first subdomain is the reserved bit in the domain HE-SIG-A.
In this implementation, physical header (Physical Header) in WUR PPDU can be HE SU PPDU Header, i.e. follows the domain RL-SIG (length is 1 OFDM symbol) and the domain HE-SIG-A after Legacy preamble closely (length is 2 OFDM symbols).Specifically, being a kind of WUR PPDU structural schematic diagram provided by the embodiments of the present application as shown in Figure 10 (a) or Figure 10 (b).WUR PPDU in Figure 10 (a) or Figure 10 (b) successively includes first part and second part, and wherein first part includes legacy preamble, the domain RL-SIG (RL-SIG is that the time domain of L-SIG in Legacy preamble repeats), the domain HE-SIG-A;Second part includes WUR load.For WUR PPDU shown in Figure 10 (a) or Figure 10 (b) in transmission, the duration that the duration that the duration of legacy preamble is generally 20 domains μ s, RL-SIG is generally 4 domains μ s, HE-SIG-A is generally 8 μ s.
Shown in content such as Figure 10 (a) or Figure 10 (b) that the domain HE-SIG-A of HE SU PPDU is included.For the domain HE-SIG-A, following subdomain: format (Format) is successively transmitted on the symbol 1 of occupancy;Wave beam changes (Beam Change);Uplink/downlink (UL/DL);Modulation coding scheme (MCS);Dual carrier modulates (Dual carrier modulation, DCM);Basic service set color (BSS Color);Retain (Reserved);Spatial reuse (Spatial Reuse);Bandwidth (Bandwidth);The sum of protection interval (Guard Interval, GI) and LTF size (size);Empty time stream number (Number of space-time stream, Nsts);It successively transmits following subdomain: transmission opportunity TXOP (Transmission Opportunity, TXOP) on the symbol 2 of occupancy;Duration (Duration);It encodes (Coding);Low density parity check code (Low Density Parity Check Code, LDPC) diacritic (Extra Symbol);Space-time block code (Space-time Block Coding, STBC);Launching beam figuration (Transmit Beamforming, TxBF);Fill factor (Padding factor) before forward error correction (Pre-Forward Error Correction, Pre-FEC);Packet extension (Packet Extension, PE) ambiguity eliminates (Disambiguity);Doppler (Doppler);Cyclic redundancy check (Cyclic Redundancy Check, CRC);Tail bit (Tail).
In this implementation, WUR instruction can be carried with MCS subdomain in HE-SIG-A, i.e., the first subdomain is MCS subdomain.The value range that MCS subdomain is defined in 802.11ax is 0 to 11, and 12 to 15 belong to retention, therefore, any one value in 12 to 15 can be used to indicate as WUR.Such as, using the value of MCS subdomain be 15 when as WUR instruction, then support 802.11ax but the equipment of not supporting WUR standard agreement is when to receive one include the HE SU PPDU physical header that MCS subdomain is 15 for one, since uncertain MCS subdomain is meaning represented by 15, therefore think that further part can not parse, therefore this PPDU further part will be no longer received and parsed through, to achieve the purpose that power saving;When one is supported the WUR equipment of 802.11ax to receive the HE SU PPDU physical header by main radio, if it is determined that MCS subdomain therein is 15, it can determine that the PPDU further part includes WUR payload, to notify the WUR of oneself to detect and receive WUR payload, main radio no longer receives and parses through further part.And before main radio detects WUR instruction, WUR can not do signal detection (for instance in Doze state), thus more power saving.
Optionally, in addition to MCS subdomain, the reserved bit in HE-SIG-A can also be used to indicate as WUR, i.e. the first subdomain is reserved bit.For example, 802.11ax provides that the bit value of reserved bit is 1, therefore when the bit value of reserved bit is 0, it can be used to indicate that current WUR PPDU further part is WUR PPDU.Its advantages are similar with the carrying WUR instruction of the domain MCS, and so it will not be repeated.
To sum up, in conjunction with the description of front, when the first equipment carries WUR instruction by the MCS subdomain in the domain HE-SIG-A or the reserved bit in the domain HE-SIG-A, if the second equipment indicates to determine to include the second part (i.e. WUR payload) in WUR PPDU according to the WUR, then the second part can be parsed by WUR when second equipment determines and meets preset condition.Wherein, it includes WUR that the preset condition, which includes: second equipment,.
Correspondingly, the second equipment can be abandoned receiving the second part, to reach power saving purpose when determination is unsatisfactory for the preset condition.
It optionally, can also include the mark of BSS belonging to the first equipment in conjunction with Figure 10 (a) or Figure 10 (b), in first part.Specifically, further including BSS Color subdomain in HE-SIG-A.BSS Color long 6bits can serve to indicate that the mark for sending the affiliated BSS of equipment of the WUR PPDU.BSS is the network as composed by AP STA associated with it, therefore BSS Color is also network identity.BSS Color facilitates the further power saving of receiving device: after receiving device (no matter 802.11ax equipment or main radio use the WUR equipment of 802.11ax) receives WUR PPDU, if it is determined that when the BSS Color of BSS Color value and oneself belonging network in the HE-SIG-A of the HE SU PPDU of WUR PPDU is mismatched, then think that the HE SU PPDU is the PPDU in other BSS, therefore no longer receive further part, without parsing further part, thus more power saving.In the present embodiment, BSS Color subdomain can also carry other for indicating the information of network identity, such as the partial bit (such as low several positions of BSSID) of BSSID.
In the embodiment of the present application using MCS as WUR instruction after, such as by MCS set 15, subdomains other in HE-SIG-A can also be redefined, for carrying other information.For example, in the embodiment of the present application, the first part in WUR PPDU that the first equipment is sent can also include the receiving end mark for receiving the receiving end of the WUR PPDU.Specifically, the part subdomain of HE-SIG-A can be redefined, for carrying the receiving end mark for receiving the receiving end of the WUR PPDU, so that main radio uses the WUR equipment more power saving of 802.11ax.For example, can be redefined to the 7th to 15 bit in second symbol of HE-SIG-A, for carrying receiving end mark, as shown in Figure 10 (a) or Figure 10 (b).Receiving end identifies the AID that can be receiving device, or PAID or WUR ID, or short mark (such as the low several positions of MAC Address generated based on receiving device MAC Address, or the cryptographic Hash of MAC Address) or other any information that can be used for identifying receiving device identity.When main radio receives the HE SU PPDU physical header of MCS=15 by main radio using the WUR equipment of 802.11ax, if the mark of receiving end included in it and the mark of oneself mismatch, then think that the WUR PPDU is not intended for oneself, therefore main radio and WUR Interface is all not necessarily to parse the WUR PPDU further part, thus more power saving.And in scheme as shown in Figure 5, main radio and WUR interface are respectively detected and are decoded to reception signal in entire WUR PPDU reception period, and two interfaces all have decoding power consumption in entire WUR PPDU duration.Obviously, the scheme of the embodiment of the present application makes the more power saving of target WUR equipment, it can be avoided third party device (non-targeted WUR equipment and support 802.11ax but the traditional WiFi equipment for not supporting WUR) entire WUR PPDU of parsing simultaneously, to make the consumption of third party device saving electricity.
It should be strongly noted that the WUR payload of WUR PPDU is possibly used for carrying group address frame, i.e. the WUR PPDU is intended for multiple equipment.At this point, the receiving end mark in HE-SIG-A should not be the mark of a certain equipment, and it should be group address mark.For example, PAID=0 indicates group address according to existing standard.Certainly, we can also define other particular values and identify as group address, for example, defining when Identity sub-domain all bits in receiving end are 1 indicates group address.
To sum up, in the prior art, entire WUR PPDU can be considered as 802.11a PPDU and is decoded by 802.11ax equipment, and it is higher to receive power consumption.In the embodiment of the present application, supports 802.11ax but the equipment of WUR standard is not supported to can determine that the WUR PPDU further part oneself can not parse according to the WUR instruction in HE-SIG-A, therefore parsing WUR PPDU further part will not be removed.Therefore, the scheme of the embodiment of the present application makes the more power saving of 802.11ax equipment.
In the prior art, when supporting that the main radio of WUR equipment of 802.11ax is active, WUR is in close state, when receiving WUR PPDU shown in Fig. 2 (a) or Fig. 2 (b), 802.11ax PPDU can be regarded as to be decoded, the decoding operate of main radio obviously compares power consumption, and when the receiving device of the WUR PPDU is precisely oneself, the main radio of the equipment can not parse the WUR PPDU.WUR PPDU is issued to guarantee that WUR equipment can always parse, WUR can only be kept to be also at reception detecting state after main radio unlatching, is i.e. two interfaces always receive signal to each and respectively detected and decoded, this obviously compares power consumption.In the embodiment of the present application, when main radio is active using the main radio of the WUR equipment of 802.11ax, WUR can be closed, and only when main radio detects WUR instruction from HE-SIG-A, just notice WUR is opened and received further part.And the introducing of BSS Color and receiving end mark, so that the main radio and WUR of the non-targeted WUR equipment of current WUR PPDU are not necessarily to parse the part WUR payload, thus more power saving.
Second of possible implementation: the first standard agreement is 802.11ax, and the physics header field includes the domain RL-SIG and the domain HE-SIG-A, and the first part is HE SU PPDU format;First subdomain is MCS subdomain in the domain HE-SIG-A or first subdomain is the reserved bit in the domain HE-SIG-A.
In the embodiment of the present application, WUR equipment is possibly used in long haul communication scene, such as sensor network (such as forest fire monitors network, urban climate monitoring network).In this case, the part PHY Header of WUR PPDU uses HE ER SU PPDU Header more suitable.
It can be as shown in Figure 11 (a) or Figure 11 (b) as the WUR PPDU of PHY Header using HE ER SU PPDU Header.Wherein, the domain RL-SIG is identical as the first possible implementation, the domain HE-SIG-A is the time domain duplication in the domain HE-SIG-A in the first possible implementation, therefore length is four OFDM symbols (length in the domain HE-SIG-A is two symbols in the first possible implementation).If the symbol that HE-SIG-A includes in the first possible implementation is symbol 1, symbol 2 (in chronological sequence sorting), the symbol that HE-SIG-A includes in second of possible implementation is in chronological sequence ordered as symbol 1, symbol 1, symbol 2, symbol 2.Although HE-SIG-A is different from the length of HE-SIG-A in the first possible implementation in second of possible implementation, the content carried is identical.The content specifically carried can refer to the description of front, and details are not described herein.
In this implementation, following subdomains in the domain HE-SIG-A be can be for carrying the first subdomain of WUR instruction:
1) BW subdomain: it to be 0 or 1 that BW subdomain is only defined in the HE ER SU PPDU format of 802.11ax, and BW subdomain is 2 or 3 and belongs to retention.Therefore, can use BW subdomain be in 2 or 3 any one value as WUR instruction.For example, indicating that HE-SIG-A includes later WUR payload when BW subdomain is 3;Alternatively, indicating that HE-SIG-A includes later WUR payload when BW subdomain is 2.
2) MCS subdomain: for HE ER SU PPDU format, providing in 802.11ax, and when BW subdomain is 0, MCS subdomain can take any one value in 0 to 2;When BW subdomain is 1, MCS subdomain can take 0.Therefore, WUR instruction can be that BW subdomain is 0 and MCS subdomain is any one value in 3 to 15, for example, BW subdomain is 0 and MCS subdomain is 15;Alternatively, WUR instruction is also possible to, BW subdomain is 1 and MCS subdomain is any one value in 1 to 15, for example, BW subdomain is 1 and MCS subdomain is 15.
3) Nsts subdomain: it is 0 or 1 that Nsts subdomain is only defined in the HE ER SU PPDU format of 802.11ax, and Nsts subdomain is that any one value then belongs to retention in 2 to 7.Therefore, can use Nsts subdomain is that any one value is indicated as WUR in 2 to 7.For example, indicating that HE-SIG-A includes later WUR payload when Nsts subdomain is 7.
4) reserved bit in HE-SIG-A: for example, 802.11ax provides that the bit value of reserved bit is 1, therefore when the bit value of reserved bit is 0, can be used to refer to current WUR PPDU further part is WUR PPDU.
To sum up, in conjunction with the description of front, when the first equipment carries WUR instruction by the MCS subdomain in the domain HE-SIG-A or the BW subdomain in the domain HE-SIG-A or the Nsts subdomain in the domain HE-SIG-A or the reserved bit in the domain HE-SIG-A, if the second equipment indicates to determine to include the WUR payload in WUR PPDU according to the WUR, then the second part can be received and parsed through by WUR when second equipment meets preset condition.Wherein, it includes WUR that the preset condition, which includes: second equipment,.
Correspondingly, the second equipment when being unsatisfactory for the preset condition, can be abandoned receiving the second part, to reach power saving purpose.
Optionally, in the implementation, the first equipment can also by the BSS Color in HE-SIG-A and redefine part subdomain (the 7th to the 15th in such as symbol 2) with carry receiving end mark, receiving device power consumption can be further decreased.
It optionally, can also include the mark of BSS belonging to the first equipment in first part.Specifically, the first equipment can indicate to send the mark of the affiliated BSS of equipment of the WUR PPDU by the BSS Color subdomain in HE-SIG-A.Specifically can be with reference to the description in the first possible implementation, details are not described herein.
Optionally, the first part in WUR PPDU that the first equipment is sent can also include the receiving end mark for receiving the receiving end of the WUR PPDU.Specifically can be with reference to the description in the first possible implementation, details are not described herein.
The third possible implementation: the first standard agreement is 802.11ac, and the physics header field includes the domain VHT-SIG-A;First subdomain is MCS subdomain in the domain VHT-SIG-A or first subdomain is the reserved bit in the domain VHT-SIG-A.
Specifically, the PHY Header in WUR PPDU can be VHT PPDU Header, the i.e. physical header of 802.11ac, including the domain Legacy preamble and VHT-SIG-A as shown in Figure 12 (a) to Figure 12 (b).Wherein, the domain VHT-SIG-A is followed closely after Legacy preamble, wherein the domain VHT-SIG-A occupies 2 symbols, and the bit that symbol 1 includes is B0 to B23, and the bit that symbol 2 includes is B0 to B23.
The subdomain that the domain VHT-SIG-A is transmitted in shared symbol 1 may include: BW;Space-Time Block Coding (Space time block coding, STBC);Group mark (Group Identifier, Group ID);Nsts;PAID;Multi-user (Multiple User, MU);Do not allow in current TXOP power saving (TXOP_PS_NOT_ALLOWED), wherein PS full name is Power Saving.
The subdomain that the domain VHT-SIG-A is transmitted in shared symbol 2 may include: short GI (Short GI);Symbolic number (Number of Symbols, the NSYM) ambiguity of short GI eliminates (Short GI NSYM Disambiguation);It is applied alone Family/multi-user coding (SU/MU Coding);LDPC additional OFDM symbol (LDPC Extra OFDM Symbol);Single user very high-throughput (Very High Throughput, VHT) modulation coding scheme (SU VHT-MCS);Multi-user coding (MU Coding);Wave beam forming (Beamformed);CRC;Tail bit.
The concrete meaning of above-mentioned subdomain can be with reference to the description in 802.11ac, and details are not described herein.
In the embodiment of the present application, WUR instruction can be carried with SU VHT-MCS (hereinafter referred to as MCS) subdomain of the B4 to B7 of symbol 2 in VHE-SIG-A, i.e. the first subdomain is MCS subdomain.Defined in 802.11ac MCS subdomain value range be 0 to 9, and 10 to 15 be MCS subdomain retention.Therefore, MCS subdomain can be used to be that any value in 10 to 15 is indicated as WUR, such as when MCS subdomain is 15, indicated in WUR PPDU including WUR load.
It should be noted that the B4 to B7 of symbol 2 has different meanings under SU and MU scene, only just for carrying MCS subdomain under SU scene.Therefore, when carrying WUR instruction by MCS subdomain, the Group ID subdomain in VHT-SIG-A should be set as SU, i.e. Group ID value should be 0 (SU UL) or 63 (SU DL).
Under the implementation, the reserved bit in VHT-SIG-A can also be used to indicate as WUR, i.e. the first subdomain is reserved bit.802.11ac provides that the reserved bit in VHT-SIG-A is set as 1, therefore when the bit value of reserved bit is 0, can be used to indicate that current WUR PPDU further part is WUR PPDU.It should be noted that, due to using PHY Header part of the VHT PPDU physical header as WUR PPDU in this implementation, therefore the equipment that can be benefited from it, other than the WUR equipment of 802.11ax equipment and main radio using 802.11ax in embodiment one, it further include the WUR equipment that 802.11ac equipment and main radio use 802.11ac, therefore equipment range of being benefited is broader.
To sum up, in conjunction with the description of front, when the first equipment carries WUR instruction by the MCS subdomain in the domain VHT-SIG-A or the reserved bit in the domain VHT-SIG-A, if the second equipment indicates to determine to include the WUR payload in WUR PPDU according to the WUR, then the second part can be parsed by WUR when second equipment determines and meets preset condition.Wherein, it includes WUR that the preset condition, which includes: second equipment,.Correspondingly, the second equipment is abandoned receiving the second part, to reach power saving purpose when determination is unsatisfactory for the preset condition.
Optionally, other than MCS subdomain and reservation bit, also PAID subdomain can be used to indicate as WUR.For example, carrying the PAID of target WUR equipment by PAID subdomain, this way can allow third party's 802.11ax and 802.11ac equipment power saving.
It optionally, can also include the mark of BSS belonging to the first equipment in first part.Specifically, can redefine other subdomains in the case where introducing WUR instruction and be identified with bearer network, the mark (if the low kilo byte of BSS Color or BSSID) etc. of the BSS as belonging to the first equipment of carrying.For example, the last dibit of symbol 1 shared by VHT-SIG-A and 4 bits of starting of symbol 2 can be redefined, for carrying the mark of BSS belonging to the first equipment.
Optionally, the first part in WUR PPDU that the first equipment is sent can also include the receiving end mark for receiving the receiving end of the WUR PPDU.Specifically, receiving end mark, such as receiving end PAID can be carried by B13 to B21 in the symbol 1 shared by VHT-SIG-A in the case where Group ID is set as 0 or 63.Receiving end mark can also have other forms, such as PAID can also be replaced with to other information for being used to indicate the receiving end current WUR PPDU mark, such as AID, and with specific reference to the description of front, details are not described herein.Optionally, when PAID=0, it also may indicate that group address identifies, with specific reference to the description of front, details are not described herein.
Compared with prior art, under the implementation, not only make 802.11ax equipment and main radio use the WUR equipment more power saving of 802.11ax, 802.11ac equipment and main radio is also made to use the WUR equipment also more power saving of 802.11ac, therefore equipment range of being benefited is wider.
4th kind of possible implementation: the first standard agreement is 802.11n, and physics header field includes the domain HT-SIG;First son Domain is MCS subdomain in the domain HT-SIG or first subdomain is the reserved bit in the domain HT-SIG.

The content that HT-SIG is included can following subdomain: MCS subdomain;Channel width (Channel Bandwidth, CBD);High-throughput (High Throughput, HT) length (Length);Smoothly (Smoothing);Non- detection (Not Sounding);Reserved bit;It polymerize (Aggregation);STBC;FEC encodes (Coding);Short GI;Extending space flow amount (Number of Extension Spatial);It flows (Strame);CRC;Tail Bits.Wherein, the LSB in Figure 13 (a) is lowest order (least significant bit), and MSB is highest order (most significant bit).
In the implementation, WUR instruction can be carried with MCS subdomain in HT-SIG, i.e. the first field is MCS subdomain.The value range that MCS subdomain is defined in 802.11n is 0 to 76, and the retention that 77 to 127 belong to MCS subdomain, therefore, can use MCS subdomain be in 77 to 127 any one value as WUR instruction.
Optionally, the reservation bit in HT-SIG can also be used to indicate as WUR, i.e. the first subdomain is reserved bit, can specifically refer to the description of front, details are not described herein.
Optionally, can also include in first part the mark of BSS belonging to the first equipment and receive the WUR PPDU receiving end receiving end mark.In the case where introducing WUR instruction, part subdomain can also be redefined to carry other information, such as the mark such as carrying receiving end mark and mark of BSS belonging to the first equipment.For example, redefining in HT-SIG symbol 1 part or all of bit in the 8th to the 23rd, for carrying receiving end mark, receiving end mark can be AID, PAID, receiving end MAC Address partial bit etc..For example, bit some or all of in preceding 10 bit is redefined in symbol 2, for carrying the mark of BSS belonging to the first equipment, if such as the low kilo byte of BSS Color or BSSID.
Compared with prior art, in the fourth possible implementation, due to the part PHY Header using HT PPDU physical header as WUR PPDU, therefore the equipment that can be benefited from it, the WUR equipment of 802.11ac is used using the WUR equipment, 802.11ac equipment, main radio of 802.11ax including 802.11ax equipment, main radio, further include 802.11n equipment, main radio use 802.11n WUR equipment, therefore be benefited equipment range it is broader.
In conjunction with the description of front, when the first equipment carries WUR instruction by the MCS subdomain in the domain HT-SIG or the reserved bit in the domain HT-SIG, if the second equipment indicates to determine to include the WUR payload in WUR PPDU according to the WUR, then the second part can be parsed by WUR when second equipment determines and meets preset condition.Wherein, it includes WUR that the preset condition, which includes: second equipment,.Correspondingly, the second equipment can be abandoned receiving the second part, to reach power saving purpose when determination is unsatisfactory for the preset condition.
Optionally, any implementation in conjunction with the first possible implementation into the 4th kind of possible implementation, the preset condition can also include: that the mark of BSS belonging to the first equipment is identical as the mark of BSS belonging to second equipment.When the second equipment is after receiving WUR PPDU, while second equipment includes WUR, second equipment also need to further determine that the first equipment send WUR PPDU in include the first equipment belonging to BSS mark with BSS belonging to the second equipment identify whether it is identical, if they are the same, then the second part in the WUR PPDU is parsed by WUR;If not identical, the second equipment is abandoned receiving the second part.
