Description

Wake-up frame sending method, access point and station

technical field

Embodiments of the present invention relate to the field of communication technologies, and in particular, to a method for sending a wake-up frame, an access point, and a station.

Background technique

In short-range wireless communication networks, the feature of low power consumption has gradually aroused extensive discussions in the industry. Especially for the development needs of the Internet of Things (Internet of Things, IoT) based on short-range wireless communication technology, the feature of low power consumption is particularly important.

When a main circuit (Main Radio, MR for short) in a station (Station, STA for short) sleeps, its power consumption will be significantly reduced, but at this time, the MR communication connection will be interrupted. The longer the MR sleep time, the lower the overall power consumption. Only when the MR remains fully awake can it complete the communication function to which it belongs. Therefore, lower power consumption will bring longer communication delay. A Wake Up Receiver (WUR for short) in a station (Station, STA for short) is generated to solve the contradiction between power consumption and delay. The WUR is used to monitor and receive an Access Point (AP) wake-up frame (Wake Up Packet, WUP) when an MR with a strong communication function sleeps, and the WUP is used to wake up the MR in a sleep state. FIG. 1 is a schematic diagram of an AP sending a wake-up frame to a WUR according to the prior art. As shown in FIG. 1 , the WUR is a component independent of the MR. When the MR is off (sleep), the WUR remains on or on for a specified period of time so that it can listen for and receive WUPs for waking up its associated MR. When the WUP received by the WUR is to wake up its associated MR, the WUR finds that the destination identifier in the WUP matches itself, and starts to wake up its associated MR, so that the MR can start its normal communication function.

On the one hand, the transmission link (Transmission Link, Tx for short) in the MR of the STA consumes a large part of the overall average power consumption of the MR. Among them, in the Tx, a power amplifier (Power Amplifier, PA for short) occupies a considerable part of the power consumption, and the PA will occupy about two-thirds of the total power consumption of the STA. Specifically, the A-type PA and the B-type PA are widely used in wireless fidelity (Wireless Fidelity, WiFi for short) and other networks that require high data accuracy because of better linear amplification characteristics. However, both the A-type PA and the B-type PA will cause a large static current consumption, that is to say, when the STA remains in a fully awake state and is in an idle state when no data is sent, it will cause unnecessary power consumption of the STA. On the other hand, there is still such a situation on the STA side. The Phase Lock Loop (PLL) and the components related to the generation of the crystal oscillator frequency, it takes about 3-5 hours from the time it is turned on to the fully wake-up state of the crystal oscillator frequency. It takes only 500-600 microseconds for STA's mixers, baseband amplifiers, and digital processing chips to enter a fully awake state. Therefore, before the other components wait for the crystal oscillator frequency-related components to enter a fully awake state, other components cause unnecessary power consumption, for example, the PA will consume a large amount of energy.

Detailed ways

The embodiments of the present invention are mainly proposed for the following three scenarios.

The first scenario: Usually the AP sends a WUP to the STA's WUR, so that the WUR wakes up the STA's MR. After the AP waits for the MR of the STA to be woken up, the STA will reply to the AP with an Acknowledgement Frame (ACK for short) or a Power Saving-Poll Frame (PS-Poll for short). Thus, the subsequent uplink/downlink data communication process is started. Figure 2 is a schematic diagram 1 of a process in which an AP sends a WUP to a STA to wake up the STA according to an embodiment of the present invention. As shown in Figure 2, after the STA receives the WUP sent by the AP, it needs a long warm-up time (4-6 milliseconds) to complete its MR into a fully awake state. During the warm-up time, the AP will always wait for the STA to reply to it with an ACK/PS-Poll. There are two previously unpredictable situations that arise at this point. In the first case, FIG. 3 is a second schematic diagram of a process in which an AP sends a WUP to a STA to wake up the STA according to an embodiment of the present invention. As shown in Figure 3, the AP may expect to interrupt subsequent communication with STA1 because it may have other urgent uplink/downlink services, and instead communicate with STA2 with emergency services, or wake up other STA2 with emergency services. For example, the AP needs to send urgent data to STA2. In the second case, FIG. 4 is a schematic diagram 3 of a process in which the AP sends a WUP to the STA to wake up the STA according to an embodiment of the present invention. As shown in FIG. 4 , the AP waits for the STA 1 to reply to the ACK/PS-Poll within the warm-up time. , the channel is idle for a long time and is occupied by other STA2, and STA2 sends a non-trigger-based uplink frame, so that STA1 cannot reply to AP ACK/PS-Poll when it is fully awakened. In a word, due to the long warm-up time in the wake-up process of the MR of the STA1, it may occur that the MR of the STA1 cannot communicate with the AP normally when the MR is fully woken up. In this case, turning on the Tx of STA1 will cause unnecessary power consumption of the PA.

The second scenario: Figure 5 is a schematic diagram 4 of the process in which the AP sends a WUP to the STA to wake up the STA according to an embodiment of the present invention. As shown in Figure 5, after the AP wakes up the STA, the STA does not need to reply ACK/PS- Poll, but the AP directly sends downlink data to the STA after sending the WUP. Therefore, in this case, if the STA opens the Tx link during the downlink data transmission time of the AP, it will cause unnecessary power consumption of the STA.

To sum up, the above two scenarios are when STA1 has been in the wake-up process (including the warm-up time and the time in the fully wake-up state), when there is no need for STA1 to send uplink data to the AP, but the STA has turned on Tx, or when the AP and the AP have When STA1 cannot transmit data normally, it will cause unnecessary power consumption of STA1.

The third scenario: the PLL in the STA and the components related to the crystal oscillator frequency generation, it takes about 3-5 milliseconds from turning on to the crystal oscillator frequency fully awake state, while other components of the STA completely enter the fully awake state only It takes 500-600 microseconds. Therefore, there are other components that cause unnecessary power consumption before waiting for the crystal oscillator frequency-related components to enter a fully awake state, so that the PA will consume a large amount of energy.

Based on the above three scenarios, the embodiments of the present invention aim to add a semi-awake field to the WUP to indicate whether the STA maintains a fully-awake state or a semi-awake state. The so-called fully awake state refers to: when the STA maintains the fully awake state, all functions of the main circuit of the STA are turned on. The so-called semi-awake state refers to: when the STA maintains the semi-awake state, some functions of the main circuit of the STA are in an open state. For example: in the semi-awake state: 1) The MR of the STA can keep its Tx still in the off state, especially its PA can be in the off state, thereby reducing power consumption. 2) The components related to the frequency of the crystal oscillator can be turned on, such as PLL, clock, etc. can be turned on, because these components require a long warm-up time, and the power consumption is less than that of the PA; 3) Other Tx components can be turned on because Its power consumption is small.

Specifically, FIG. 6 is a schematic flowchart of a method for sending a wake-up frame provided by an embodiment of the present invention. As shown in FIG. 6 , the method includes the following processes:

Step S601: the access point AP generates a first wake-up frame;

Step S602: The AP sends a first wake-up frame to the STA, where the first wake-up frame includes: a half-wake-up field.

FIG. 7 is a schematic diagram of a frame format of a WUP provided by an embodiment of the present invention. As shown in FIG. 7 , when an AP sends a WUP, an 802.11 traditional preamble (L-Preamble) can be sent in advance to let other 802.11 devices back off to avoid Wireless channel occupation conflicts. After the traditional preamble is the WUP preamble (WUR-Preamble), the WUR-Preamble is used for the WUR to complete the synchronization process of WUP reception. The following WUR signaling part (WUR-SIG) can be used to indicate the length of the subsequent WUR information payload part (WUR-Payload). The WUR-Payload includes: a Pre-wake field (PWF for short), the PWF is used to instruct the STA to remain in a fully awake state or a semi-awake state, and the WUR-Payload part may also include a pre-wake field to indicate that the awakened STA is awake After the subsequent behavior instruction, the embodiment of the present invention does not limit the behavior instruction.

In this embodiment of the present invention, since the first wake-up frame sent by the AP to the STA includes: a semi-awake field, when the STA is in a semi-awake state, the STA only needs to enable some functions, for example, the MR of the STA can keep its Tx still off In particular, the PA can be turned off, and the components related to the frequency of the crystal oscillator can be turned on, such as PLL, clock, etc. can be turned on; other Tx components can be turned on, thereby reducing unnecessary power consumption of the STA.

Optionally, it also includes: when the semi-awake field indicates that the STA maintains the semi-awake state, the semi-awake field is further used to instruct the STA to maintain the semi-awake state until the STA receives the second wake-up frame, and the second wake-up frame is used to indicate the STA maintains the fully awake state;

or,

When the semi-awake field indicates that the STA maintains the semi-awake state, the semi-awake field is also used to indicate that if the STA does not receive the second wake-up frame within the semi-awake time Stay asleep at the end of the half-wake duration. For example: when STA1 is in a semi-awake state, if the AP is going to prepare data transmission with STA1, but because the AP is bursting with STA2 for uplink or downlink data transmission, in this case, STA1 will not receive other APs. The WUP with PWI=0, then STA1 maintains the sleep state again, which avoids unnecessary power consumption in the idle state caused by the AP interrupting the subsequent communication with the STA1 after being woken up by the AP.

In the prior art, after the STA receives the WUP sent by the AP, the STA remains in a fully awake state, but in fact, on the one hand, after the STA is woken up, it may not be able to communicate with the AP normally. On the other hand, it takes about 3-5 milliseconds for the components related to the crystal oscillator frequency in the STA to remain fully awake, while other components of the STA only need 500-600 microseconds to maintain the fully awake state. Therefore, there are other components that cause unnecessary power consumption before waiting for the crystal frequency related components to remain fully awake. To sum up, the above two aspects cause unnecessary power consumption of the STA.

In this embodiment of the present invention, when the STA maintains the semi-awake state, the semi-awake field is further used to instruct the STA to maintain the semi-awake state until the STA receives the second wake-up frame, and the second wake-up frame is used to instruct the STA to maintain the semi-awake state. or, when the semi-awake field indicates that the STA maintains the semi-awake state, the semi-awake field is also used to indicate that if the STA does not receive the second wake-up frame, then stay in sleep state at the end of the half-wake-up period. Thus, unnecessary power consumption of the STA is reduced.

The above-mentioned semi-awakened field can adopt the following two optional methods:

The first optional way: FIG. 8 is a schematic diagram of the format of the semi-wake field provided by an embodiment of the present invention. As shown in FIG. 8 , the semi-wake field includes: a pre-wake indication (Pre-wake Indication, PWI for short) subfield and Pre-wake Duration (PWD for short) subfield; wherein the semi-wake indication subfield is used to instruct the STA to maintain the fully awake state or the half-wake state. The half-awakening duration subfield is used to indicate the half-awakening duration for maintaining the half-awakening state. In the embodiment of the present invention, the half-awakening field occupies 8 bits, the half-awakening indication subfield occupies 1 bit, and the half-awakening duration subfield occupies 7 bits.

Among them, the instructions of PWI are shown in Table 1

Table I

Of course, PWI=1 can also be used to indicate that the main circuits of the awakened STA can be all turned on, without maintaining the semi-awake state proposed in the embodiment of the present invention, and PWI=0 to indicate that the main circuit of the awakened STA can keep the main circuit of the embodiment of the present invention. The proposed semi-awake state. This embodiment of the present invention does not limit this.

See Table 2 for the instructions of PWD

Table II

FIG. 9 is a schematic diagram 5 of a process in which an AP sends a WUP to a STA to wake up the STA according to an embodiment of the present invention. As shown in FIG. 9 , when PWI=0, after the STA receives the WUP, the STA enables all functions of its main circuit , that is, keep the fully awake state, so that the ACK/PS-Poll response frame can be returned to the AP. Optionally, it also includes: a response behavior field, where the field is used to respond to a behavior field that may exist in the WUP.

When PWI=1, there are two situations after the STA receives the WUP. Specifically, FIG. 10 is a schematic diagram 6 of a process in which the AP sends a WUP to the STA to wake up the STA according to an embodiment of the present invention. As shown in FIG. 10 , within the half wake-up time, if the STA receives another WUP and sends it PWI=0 WUP, then exit the semi-awakened state, and fully turn on all the functions of its MR, that is, maintain the fully-awakened state, after x microseconds, the STA returns ACK/PS-Poll to the AP. Optionally, the STA returns an ACK to the AP. After /PS-Poll, the STA sends a response message to the AP in response to the behavior field. FIG. 11 is a schematic diagram 7 of a process in which an AP sends a WUP to a STA to wake up a STA according to an embodiment of the present invention. As shown in FIG. 11 , if no WUP with PWI=0 sent to it is received within the half wake-up time, Then, at the end of the half-awakening period, the STA exits the half-awakening state and maintains the sleeping state again.

The second optional way: when the semi-awake field indicates that the STA remains in the semi-awake state, the semi-awake field is also used to indicate the half-awake duration.

Specifically, the main difference between the second optional manner and the first optional manner is the change to the PWF format. In the second optional mode, the PWF is no longer divided into the two subfields in the first optional mode: PWI and PWD, but the PWF as a whole. Specifically, the indication description of the PWF is shown in Table 3.

As shown in FIG. 14 , when the value of the PWF is between 00000000 and 11111111, the PWF instructs the STA to remain semi-awake state. Within the half-awakening time period indicated by the PWF, if a WUP with a PWF value of 00000000 is received, it exits the half-awakening state, and maintains the fully-awakening state according to the indication of the PWF value of 00000000.

FIG. 15 is a schematic diagram 11 of a process in which an AP sends a WUP to a STA to wake up the STA according to an embodiment of the present invention. As shown in FIG. 15 , when the value of the PWF is between 00000000 and 11111111, the PWF instructs the STA to keep half Awake state. If no WUP with a PWF value of 00000000 is received within the half-awake time period, the STA maintains the sleep mode again.

To sum up, in this embodiment of the present invention, since the first wake-up frame sent by the AP to the STA includes the semi-awake field, when the STA is in the semi-awake state, the STA only needs to enable some functions, thereby reducing unnecessary power consumption of the STA.

Considering that some WUPs are long in length, these WUPs need to be sent in fragments to improve the transmission success rate of the WUPs. For convenience, the sliced WUP is called a wake-up subframe.
