[0086] As shown in FIG. 1, the communication system 100 includes a first AP 101 and a STA 102, where the STA 102 is an associated STA that establishes an association with the first AP.
[0087] In some embodiments, the first AP includes at least one of a TWT Responding STA (TWT responding end; TWT is Target Wake Time, and STA is Station), a TWT Scheduling AP (TWT scheduling AP; AP is Access Point), and an R-TWT Scheduling AP.
[0088] The associated STA 102 includes at least one of a TWT Requesting STA (TWT initiating end), a TWT Scheduled STA (TWT scheduled STA), and an R-TWT Scheduled STA (R-TWT scheduled STA).
[0089] In some embodiments, the STA includes, for example, a wireless communication chip supporting WiFi communication function, a wireless sensor, or a wireless communication terminal. Optionally, the wireless communication terminal includes, for example, at least one of a mobile phone, a wearable device, an Internet of Things (IoT) device supporting WiFi communication function, a WiFi communication function enabled car, a smart car, a tablet computer (Pad), a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in smart grid, a wireless terminal device in transportation safety, a wireless terminal device in smart city, a wireless terminal device in smart home, and the like, but is not limited thereto.
[0090] In particular, the STA can be a terminal device or a network device with a wireless fidelity (WiFi) chip. Optionally, the STA 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 like, and the next generation 802.11 protocol, but is not limited thereto.
[0091] In some embodiments, the AP can be an access point for a mobile terminal to enter a wired network. The AP serves as 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. In particular, the AP can be a terminal device or a network device with a wireless fidelity 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 like, and the next generation 802.11 protocol, but is not limited thereto.
[0092] 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.
[0093] 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 exemplary, and the communication system can include all or part of the subjects in FIG. 1, or other subjects other than those in FIG. 1.

[0094] 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 a first non-AP STA 103 having some association within a certain coverage area. One situation of association is that the 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 a first AP 104, and other STAs in the network are associated with it. Other stations in the BSS network that are not central stations are called terminals, also called non-AP STAs. When describing a STA, it is not necessary to distinguish between AP and non-AP STA. 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.
[0095] FIG. 2 is one of the interaction schematic diagrams of the device power saving method according to an embodiment of the present disclosure. As shown in FIG. 2, the above method includes:
[0096] In step 201, the first access point device AP determines a first wireless frame; wherein the first wireless frame is used to suspend or postpone a target wake time service period (TWT SP) of a first target wake time mechanism (TWT Agreement, or target wake time protocol) established between the first AP and an associated STA of the first AP.
[0097] The first AP comprises at least one of a TWT responding STA, a TWT scheduling AP, and a R-TWT scheduling AP; and the associated STA comprises at least one of a TWT requesting STA, a TWT scheduled STA, and a R-TWT scheduled STA.
[0098] In a WLAN, power management modes mainly include an active mode and a power save mode; the power save mode mainly includes a doze state and an awake state; a station device working in the power save mode switches between the doze state and the awake state, thereby reducing a high energy consumption state time of the station device, and achieving the power saving purpose while ensuring communication quality. In a next-generation 802.11 protocol, the power save mode can further include one or more of a dynamic power save mode, a schedule power save mode, and an unscheduled power save mode.
[0099] Optionally, in the embodiments of the present disclosure, the first AP supports at least one of a dynamic power save mode, a schedule power save mode, and an unscheduled power save mode; and the first TWT Agreement comprises at least one of an Individual TWT Agreement, a Broadcast TWT Agreement, and a R-TWT Agreement.
[0100] Further, in the WLAN, Target Wake Times (TWT) is also a technology for energy saving, aiming to further reduce the power consumption of Wi-Fi network. Specifically, the TWT technology determines the sleep and wake-up time and frequency of the STA by making the STA and the AP negotiate the service time (SP), and the STA keeps active and communicates in the service time, so as to sleep in the time outside the service time to achieve the purpose of energy saving. In addition, the TWT technology can also make the AP provide higher quality service to multiple STAs, minimize the competition or overlap, and improve the spectrum efficiency while reducing the power consumption of the Wi-Fi network.
[0101] Specifically, the TWT operation in the embodiments of the present disclosure determines the sleep and wake-up time and frequency of the TWT Requesting STA by the TWT Requesting STA and the TWT Responding STA negotiating to establish the TWT Agreement, or determines the sleep and wake-up time and frequency of the TWT Scheduled STA by the TWT Scheduled STA and the TWT Scheduling AP negotiating to establish the TWT Agreement.
[0102] Optionally, the TWT Agreement includes a periodic TWT Agreement or a non-periodic TWT Agreement, and each TWT Agreement contains at least one SP. The TWT Requesting STA / TWT Scheduled STA / R-TWT Scheduled STA keeps active and communicates in the SP of the corresponding TWT Agreement, and sleeps in the time outside the SP to achieve the purpose of energy saving.
[0103] For example, in the case that the TWT Agreement contains at least two SPs, before the start of each SP of the TWT Agreement, the TWT Requesting STA / TWT Scheduled STA / R-TWT Scheduled STA wakes up, communicates with the corresponding TWT Responding STA / R-TWT Scheduling AP within the SP, and enters the sleep state after the current SP ends; after a specified interval, the TWT Requesting STA / TWT Scheduled STA / R-TWT Scheduled STA re-wakes up and enters the next SP.
[0104] Through the above TWT Operation mechanism, the power saving of the TWT Requesting STA / TWT Scheduled STA / R-TWT Scheduled STA end can be mainly realized, and the corresponding TWT Responding STA / R-TWT Scheduling AP is usually in the Active mode. Only when the Responder PM Mode (power management mode of the responder; PM means power management) field is set to 1 in the TWT Agreement negotiation process, the TWT Responding STA / R-TWT Scheduling AP enters the sleep state outside the SP corresponding to the TWT Agreement. Moreover, when the TWT Responding STA is an AP, only when all non-AP STAs associated with the AP support the TWT Operation, and the TWT Required field in the HE Operation element (High-Efficiency Operation element) sent by the AP is set to 1, the TWT Responding STA can set the Responder PM Mode field to 1.
[0105] In UHR, the vision is to improve the reliability of wireless local area network (WLAN) connection, reduce the delay, improve the manageability, increase the throughput at different signal to noise ratio (SNR) levels and reduce the device level power consumption, etc. The wireless access point (station) device can work in a lower capability communication mode, for example, in the communication mode, the wireless access point (station) device transmits and receives at 20MHz, 1 spatial stream (SS) and a lower rate. And in the case that the wireless access point (station) device works in the low capability communication mode, the wireless access point (station) device can switch from the low capability communication mode to the communication mode with higher communication parameter values in the case of receiving a specific wireless frame (for example, an initial control frame).
[0106] In the embodiments of the present disclosure, in order to make the device in the current TWT Operation mechanism more power saving and meet the UHR requirements, the current TWT Operation mechanism needs to be further enhanced.
[0107] Optionally, in the embodiments of the present disclosure, in the case that the first AP is a TWT Responding STA, the associated STA can be a TWT Requesting STA, one TWT Responding STA can negotiate with one TWT Requesting STA (that is, the number of associated STAs can include one) to establish an Individual TWT Agreement (single TWT Agreement, or individual TWT Agreement), that is, the Individual TWT Agreement is an agreement established between two devices.
[0108] Optionally, in some embodiments, in case the first AP is a TWT Scheduling AP, the associated STA can be a TWT Scheduled STA, one TWT Scheduling AP can negotiate and establish a B-TWT Agreement (Broadcast TWT Agreement) or a R-TWT Agreement (Restricted TWT Agreement) with one or more TWT Scheduled STAs (i.e. the number of associated STAs can include one or more), i.e. the B-TWT Agreement or the R-TWT Agreement is an agreement established between one scheduling end and one or more scheduled ends, the B-TWT Agreement or the R-TWT Agreement can be initiated by the scheduling end, and the one or more scheduled ends actively respond (i.e. the scheduled end actively joins the TWT Agreement initiated by the scheduling end) or passively respond (i.e. the scheduled end is invited by the scheduling end to join the TWT Agreement initiated by the scheduling end). Wherein, the TWT Scheduling AP can be an AP, and the TWT Scheduled STA can be a STA.
[0109] In the embodiments of the present disclosure, the first AP negotiates and establishes a first target wake time agreement (TWT Agreement) with the associated STA; the first TWT Agreement includes one or more service periods (SPs); optionally, the first TWT Agreement includes at least one of the following contents:
[0110] Target wake time (TWT), indicating the target wake time of the first TWT Agreement, for example, the start time of the target wake time, or the start time of the TWT SP.
[0111] Target wake time interval (TWT Wake Interval), indicating the interval between the start times of two consecutive TWT SPs of the first TWT Agreement.
[0112] Nominal minimum TWT wake duration, indicating the minimum time required for the associated STA to complete frame exchange with the first AP in each TWT SP of the first TWT Agreement.
[0113] In the embodiments of the present disclosure, when there is a partial TWT SP suspension or postponement between the first AP and the associated STA, the first AP determines a first wireless frame, and the first wireless frame is used to suspend or postpone a TWT SP of a first TWT Agreement established between the first AP and the associated STA; optionally, the suspended or postponed TWT SP can be a next TWT SP at the current time; or the suspended or postponed TWT SP is marked by a start time of the TWT SP, for example, the suspended or postponed TWT SP is identified by the start time of the TWT SP.
[0114] The first AP determines a first wireless frame and sends the first wireless frame to the associated STA.
[0115] Optionally, the first wireless frame can be a unicast frame, for example, a TWT Information frame.
[0116] It can also be a broadcast frame, for example, a management frame carrying a TWT Information field.
[0117] After sending the first wireless frame or receiving response information of the first wireless frame from the associated STA, the first AP enters a first capability mode or a Doze state in the suspended or postponed TWT SP; optionally, the suspended or postponed TWT SP can be any TWT SP in the first TWT Agreement.
[0118] The first capability mode and the second capability mode of the first AP include at least one same communication parameter, and the value of at least one communication parameter is lower in the first capability mode than in the second capability mode.
[0119] The first capability mode and the second capability mode can have the same type of working parameters (communication parameters), and at least one working parameter of the first capability mode is lower than that of the second capability mode; for example, bandwidth, spatial stream (SS), modulation and coding scheme (MCS) mode, etc. For example, the first capability mode can also be a listening state or a low-power communication stage, for example, the working parameters are 20MHz basic bandwidth, the number of SS is 1, and the MCS mode is, for example, from MCS0 to MCS7. The second capability mode has, for example, working parameters greater than or equal to 20MHz, the BW can also be 40 / 80 / 160 (80+80) / 320MHz, the number of SS is greater than or equal to 2, and the MCS mode is, for example, from MCS6 to MCS14, etc.
[0120] Optionally, in some embodiments, the second capability mode can be referred to as a High Capabilities (HC) mode (or a full Capabilities mode); and the first capability mode can be referred to as a Low Capabilities (LC) mode.
[0121] After sending the first wireless frame, the first AP enters the first capability mode or the Doze state within the suspended or postponed TWT SP (i.e., within the originally scheduled TWT SP) to reduce energy consumption;
[0122] Alternatively, after the first AP receives response information of the first wireless frame from the associated STA, the first AP enters the first capability mode or the Doze state within the suspended or postponed TWT SP (i.e., within the originally scheduled TWT SP); wherein the response information is used to indicate a reception confirmation of the first wireless frame. Optionally, in the embodiments of the present disclosure, the response message can be an ACK frame or a Response frame corresponding to the first wireless frame.
[0123] Specifically, when the first AP determines to suspend or postpone the originally scheduled TWT SP, the first AP remains in an active state and communicates within the originally scheduled TWT SP; and after the first AP determines to suspend or postpone the originally scheduled TWT SP, the first AP will not communicate within the time of the originally scheduled TWT SP, and thus the first AP enters the first capability mode or the Doze state to achieve the purpose of energy saving.
[0124] In the embodiments of the present disclosure, when the first AP is a TWT Responding STA or a TWT Scheduling AP, the first AP informs a TWT Requesting STA or a TWT Scheduled STA of a TWT SP that needs to be suspended or postponed through the first wireless frame; after the first AP sends the first wireless frame or the first AP receives a response message of the first wireless frame, the first AP enters the low capability mode or the Doze state to avoid energy consumption caused by still being in an active state within the suspended or postponed TWT SP. The embodiments of the present disclosure are beneficial to reduce energy consumption of the AP as a TWT Responding STA / R-TWT Scheduling AP within the suspended or postponed TWT SP, reduce energy consumption of the access point AP, and further improve transmission efficiency.
[0125] Referring to FIG. 3, the second interaction schematic diagram of the device power saving method according to the embodiments of the present disclosure is shown, and the method comprises the following steps:
[0126] Step 301, a first access point device AP determines a first wireless frame; wherein the first wireless frame is used to suspend or postpone a TWT SP of a first TWT Agreement established between the first AP and an associated STA of the first AP; the first wireless frame is a Unicast message frame, and the associated STA includes a first STA, i.e., the first wireless frame is sent only to the first STA.
[0127] The first AP includes a TWT Responding STA, and the first STA is a TWT Requesting STA; the first capability mode and a second capability mode of the first AP include at least one same communication parameter, and a value of the at least one communication parameter is lower in the first capability mode than in the second capability mode.
[0128] Step 302, the first wireless frame is sent to the first STA.
[0129] Step 303, response information of the first STA to the first wireless frame is received.
[0130] Step 3041, the first TWT Agreement is an Individual TWT, and the first AP enters a power saving state outside the TWT SPs corresponding to the first TWT Agreement, then after the response information of the first STA to the first wireless frame is received, the first AP enters a Doze state in the suspended or postponed TWT SP.
[0131] The first AP enters a power saving state outside the TWT SPs corresponding to the first TWT Agreement, for example, the Responder PM Mode subfield is set to 1 when the first TWT Agreement is negotiated and established. It can be understood that in the embodiments of the present disclosure, "outside the TWT SPs corresponding to the first TWT Agreement" means in time outside the TWT SPs corresponding to the first TWT Agreement.
[0132] The first TWT Agreement is an Individual TWT Agreement established between the first AP and the first STA; therefore, after the response information of the first STA to the first wireless frame is received, the first AP can enter a Doze state in the suspended or postponed TWT SP, for example, turn off its transceiver link, and not perform transceiving operation, with extremely low power consumption.
[0133] Step 3042, the first TWT Agreement is an Individual TWT Agreement, and the first AP enters an active state outside the TWT SPs corresponding to the first TWT Agreement, then after receiving the response information of the first STA to the first wireless frame, the first AP enters a first capability mode in the suspended or postponed TWT SP.
[0134] Wherein, the first AP enters an active state outside the TWT SPs corresponding to the first TWT Agreement, for example, the Responder PM Mode subfield is set to 0 when negotiating to establish the first TWT Agreement; because the first AP enters an active state outside the TWT SPs corresponding to the first TWT Agreement; therefore, after receiving the response information of the first STA to the first wireless frame, the first AP can enter a first capability mode in the suspended or postponed TWT SP, for example, a listening state or a low-power communication phase, to ensure normal communication with lower power consumption.
[0135] Step 305, after the first STA sends the response information to the first AP, it enters a Doze state in the suspended or postponed TWT SP.
[0136] Wherein, in order to achieve power saving on the first STA side, the first STA also enters a Doze state in the suspended or postponed TWT SP after sending the response information to the first AP.
[0137] Referring to FIG. 4, the interaction diagram three of the device power saving method according to the embodiment of the present disclosure, the method comprises:
[0138] Step 401, a first access point device AP determines a first wireless frame; wherein, the first wireless frame is used to suspend or postpone the TWT SP of the first TWT Agreement established between the first AP and its associated STA.
[0139] The first wireless frame is a Unicast message frame, and the associated STA includes a first STA, that is, the first wireless frame is only sent to the first STA;
[0140] The first TWT Agreement is a Broadcast TWT or a Restricted TWT. The first AP includes at least one of a TWT Scheduling AP and an R-TWT Scheduling AP; one TWT Scheduling AP or R-TWT Scheduling AP can negotiate and establish a B-TWT Agreement (Broadcast TWT Agreement) or R-TWT Agreement (Restricted TWT Agreement) with one or more TWT Scheduled STAs or R-TWT Scheduled STAs (i.e., the number of associated STAs can include one or more).
[0141] The first capability mode and the second capability mode of the first AP include at least one same communication parameter, and a value of the at least one communication parameter is lower in the first capability mode than in the second capability mode.
[0142] Step 402, sending the first wireless frame;
[0143] Step 403, receiving response information of the first wireless frame from the associated STA;
[0144] Step 4041, the first TWT Agreement includes the first STA and other STAs. The first AP enters a power saving state outside the TWT SPs corresponding to the first TWT Agreement, and after receiving the response information of the first wireless frame from the first STA, the first AP enters the first capability mode in the suspended or postponed TWT SP.
[0145] The first AP enters a power saving state outside the TWT SPs (TWT SPs represent one or at least two TWT SPs) corresponding to the first TWT Agreement, for example, the Responder PM Mode subfield is set to 1 when negotiating and establishing the first TWT Agreement.
[0146] In the case that the first AP is a TWT Scheduling AP, the number of members of the first TWT Agreement (TWT Scheduled STAs) can include one or more; in the case that the number of TWT Scheduled STAs includes multiple (i.e., at least two), if the first AP receives the response information of the first STA to the first wireless frame, the first AP can enter the first capability mode, in which the first AP can monitor specific frames, such as initial control frames; when the first AP receives the initial control frames sent by other TWT Scheduled STAs, the first AP switches from the first capability mode to the second capability mode or the active mode to ensure communication with other TWT Scheduled STAs.
[0147] In the case that the number of members of the first TWT Agreement (TWT Scheduled STAs) includes one, if the first AP receives the response information of the first STA to the first wireless frame, the first AP enters the Doze state in the suspended or postponed TWT SP after the first AP enters the Doze state in the TWT SPs corresponding to the first TWT Agreement.
[0148] In the case that the number of members of the first TWT Agreement (TWT Scheduled STAs) includes one, if the first AP receives the response information of the first STA to the first wireless frame, the first AP enters the Doze state in the suspended or postponed TWT SP after the first AP enters the Doze state in the TWT SPs corresponding to the first TWT Agreement.
[0149] In the case that the number of members of the first TWT Agreement (TWT Scheduled STAs) includes one, if the first AP receives the response information of the first STA to the first wireless frame, the first AP enters the Doze state in the suspended or postponed TWT SP after the first AP enters the Doze state in the TWT SPs corresponding to the first TWT Agreement.
[0150] In the case that the first AP is a TWT Scheduling AP, the number of members of the first TWT Agreement (TWT Scheduled STAs) can include one or more; in the case that the number of TWT Scheduled STAs includes multiple (i.e., at least two), if the first AP receives the response information of the first STA to the first wireless frame, the first AP can enter the Active Mode to ensure communication with other TWT Scheduled STAs.
[0151] It can be understood that, if the first AP receives the response information of all TWT Scheduled STAs, the first AP enters the Doze state in the suspended or postponed TWT SP.
[0152] Step 4044, the members of the first TWT Agreement only include the first STA, the first AP enters the Active state outside the TWT SPs corresponding to the first TWT Agreement, and after receiving the response information of the first STA to the first wireless frame, the first AP enters the first capability mode in the suspended or postponed TWT SP.
[0153] Wherein, if the members of the first TWT Agreement only include the first STA, there is no other TWT Scheduled STA communicating with the first AP in the suspended or postponed TWT SP; the first AP enters the first capability mode instead of the Active mode, so as to reduce the energy consumption of the first AP as much as possible.
[0154] Step 405, after the first STA sends the response information to the first AP, the first STA enters the Doze state in the suspended or postponed TWT SP.
[0155] Wherein, in order to realize the power saving of the first STA side, the first STA enters the Doze state in the suspended or postponed TWT SP after sending the response information to the first AP.
[0156] Referring to FIG. 5, the third interaction diagram of the device power saving method according to the embodiment of the present disclosure is shown, and the method comprises:
[0157] Step 501, a first access point device AP determines a first wireless frame; wherein the first wireless frame is used to suspend or postpone the TWT SP of the first TWT Agreement established between the first AP and its associated STA; the first wireless frame is a broadcast (Broadcast) message frame; that is, the first message frame is sent to multiple associated STAs.
[0158] Wherein, the first AP includes at least one of a TWT Responding STA, a TWT Scheduling AP and an R-TWT Scheduling AP; the first capability mode and the second capability mode of the first AP include at least one same communication parameter, and the value of at least one of the communication parameters is lower in the first capability mode than in the second capability mode.
[0159] Step 502, the first wireless frame is sent;
[0160] Step 5031, the first TWT Agreement is Individual TWT, Broadcast TWT Agreement or Restricted TWT Agreement, and the first AP enters the power saving state outside the TWT SPs corresponding to the first TWT Agreement, then the first AP enters the Doze state in the suspended or postponed TWT SP.
[0161] Wherein, the first AP enters the power saving state outside the TWT SPs corresponding to the first TWT Agreement, for example, the Responder PM Mode subfield of the first wireless frame is set to 1.
[0162] Step 5032, the first TWT Agreement is Individual TWT, Broadcast TWT Agreement or Restricted TWT Agreement, and the first AP enters the active state outside the TWT SPs corresponding to the first TWT Agreement, then the first AP enters the first capability mode in the suspended or postponed TWT SP.
[0163] Wherein, the first AP enters the active state outside the TWT SPs corresponding to the first TWT Agreement, for example, the Responder PM Mode subfield of the first wireless frame is set to 0.
[0164] Step 504, after the first STA receives the first wireless frame, enters the Doze state in the suspended or postponed TWT SP.
[0165] In the embodiments of the present disclosure, when the first AP is a TWT Responding STA or a TWT Scheduling AP or an R-TWT Scheduling AP, the first AP informs a TWT Requesting STA or a TWT Scheduled STA or an R-TWT Scheduled STA of a TWT SP that needs to be suspended or postponed through a first wireless frame; after the first AP sends the first wireless frame or the first AP receives a response message of the first wireless frame, the first AP enters a low-capability mode or a doze state, so as to avoid energy consumption caused by the first AP still being in an active state in the suspended or postponed TWT SP. The embodiments of the present disclosure are beneficial to reducing energy consumption of the AP as a TWT Responding STA / R-TWT Scheduling AP / R-TWT Scheduling AP in the suspended or postponed TWT SP, reducing energy consumption of an access point AP end, and further improving transmission efficiency.
