[0090] As shown in FIG. 1, the communication system 100 includes a first device 101 and a second device 102.

[0099] 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 in the embodiments of the present disclosure. It can be known by those skilled in the art that, with the evolution of system architecture and the appearance of new business scenarios, the technical solutions proposed in the embodiments of the present disclosure are also applicable to similar technical problems.

[0100] The embodiments of the present disclosure described below can be applied to the communication system 100 shown in FIG. 1 or part of the subjects, 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 FIG. 1. The number and form of each subject is arbitrary, each subject can be real or virtual, the connection relationship between each subject is exemplary, each subject can not be connected or can be connected, the connection can be in any way, can be direct connection or indirect connection, can be wired connection or wireless connection.

[0101] The embodiments of the present disclosure can be applied to a Wireless Local Area Network (WLAN), for example, a local area network using an 802.11 series protocol. In the WLAN, a Basic Service Set (BSS) is a basic component of a WLAN. A BSS network is composed of station devices having some association within a certain coverage area. One situation of association is that the stations directly communicate with each other in an ad hoc network, which is referred to as an Independent Basic Service Set (IBSS). Another more common situation is that there is only one central station having a full-time management BSS in the BSS network, which is referred to as an access point device, and the other stations in the BSS network that are not APs are referred to as terminals, also referred to as non-AP STAs, and the AP and the non-AP STA are collectively referred to as STAs. When describing the STA, it is not necessary to distinguish between the AP and the non-AP STA. In the same BSS network, due to distance, transmission power, and the like, one STA cannot detect other STAs far away from it, and the two are each other's hidden nodes.

[0102] Fig. 2 is an interaction diagram of a device power saving management method according to an embodiment of the present disclosure. As shown in Fig. 2, the method includes:

[0103] In step 201, when the first device 101 is in a first capability communication mode, the first device 101 switches from the first capability communication mode to a second capability communication mode before a Service Period (SP) of a TWT Agreement (Target Wake Time) negotiated with one or more second devices 102 arrives.

[0104] The first device 101 includes at least one of a TWT Responding STA and a TWT Scheduling AP; and the second device 102 includes at least one of a TWT Requesting STA and a TWT Scheduled STA.

[0105] The parameter value of at least one communication parameter in the first capability communication mode is less than the parameter value in the second capability communication mode, and the communication parameter value in the second capability communication mode is determined based on the communication parameter value supported by one or more second devices 102 within the SP of the TWT Agreement.

[0106] The Target Wake Time (TWT) Operation establishes a TWT Agreement through negotiation between a TWT Requesting STA and a TWT Responding STA, and determines the time and frequency of sleep and wake-up of the TWT Requesting STA; or establishes a TWT Agreement through negotiation between a TWT Scheduled STA and a TWT Scheduling AP, and determines the time and frequency of sleep and wake-up of the TWT Scheduled STA.

[0107] 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 keeps active and communicates in the SP of the corresponding TWT Agreement, and sleeps at other times to achieve the purpose of energy saving.

[0108] For example, in the case where 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 wakes up, communicates with the corresponding TWT Responding STA / TWT Scheduling AP in the SP, and enters the sleep state after the end of the current SP; after a specified interval, the TWT Requesting STA / TWT Scheduled STA wakes up again and enters the next SP.

[0109] Through the above TWT Operation mechanism, the power saving of the TWT Requesting STA / TWT Scheduled STA end can be mainly realized, and the corresponding TWT Responding STA / TWT Scheduling AP is usually in the Active state. Only when the Responder PM Mode (power management) field in the TWT Agreement is set to 1, the TWT Responding STA / TWT Scheduling AP enters the sleep state outside the SP of the TWT Agreement. And when the TWT Responding STA is an AP, only when all non-AP STAs associated with the AP support the SP of the TWT Agreement, 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.

[0110] In UHR (Ultra High Reliability), the vision is to improve the reliability of wireless local area network (WLAN) connections, reduce latency, improve manageability, increase throughput at different signal to noise ratio (SNR) levels, and reduce device level power consumption, etc. A wireless access point (station) device can work in a lower capability communication mode, for example, in which the wireless access point (station) device transmits and receives at 20MHz, 1 spatial stream (SS), and a lower rate. Also, 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 a communication mode with higher communication parameter values in the case that a specific wireless frame (e.g., an initial control frame) is received.

[0111] In order to make the devices in the current TWT Operation mechanism more power saving, in line with the UHR requirements, the current TWT Operation mechanism needs to be further enhanced.

[0112] In the embodiments of the present disclosure, it is found that at least one of the following problems may be encountered when further enhancing the current TWT Operation mechanism: (1) If the TWT Responding STA / TWT Scheduling AP is controlled to be in a lower capability communication mode in order to further save power of the TWT Responding STA / TWT Scheduling AP, how does the TWT Responding STA / TWT Scheduling AP perform state switching after the TWT Responding STA / TWT Scheduling AP and the corresponding TWT Requesting STA / TWT Scheduled STA negotiate to establish a TWT Agreement, so as to ensure effective transmission with the TWT Requesting STA / TWT Scheduled STA within the SP of the TWT Agreement; (2) After the TWT Responding STA / TWT Scheduling AP and the corresponding TWT Requesting STA / TWT Scheduled STA negotiate to establish a TWT Agreement, if the TWT Responding STA / TWT Scheduling AP switches from the lower capability communication mode to a communication mode with higher communication parameter values, but the communication parameter values of the higher communication mode are too small, for example, the channel bandwidth or the maximum number of supported spatial streams after switching is less than the transmission / reception bandwidth / space stream number supported by the corresponding TWT Requesting STA / TWT Scheduled STA, the transmission within the SP of the TWT Agreement may also fail; (3) After the TWT Responding STA / TWT Scheduling AP and the corresponding TWT Requesting STA / TWT Scheduled STA negotiate to establish a TWT Agreement, if the TWT Responding STA / TWT Scheduling AP switches from the lower capability communication mode to a communication mode with higher communication parameter values, but the communication parameter values of the higher communication mode are too large, for example, the channel bandwidth or the maximum number of supported spatial streams after switching is much larger than the transmission / reception bandwidth / space stream number supported by the corresponding TWT Requesting STA / TWT Scheduled STA, the frequency resource may be wasted, and the problem of increased energy consumption at the TWT Responding STA / TWT Scheduling AP end may also occur.

[0113] Therefore, in the embodiments of the present disclosure, the action of the first device 101 is further specified, and in the case that the first device 101 is in the first capability communication mode, the first device 101 switches from the first capability communication mode to the second capability communication mode before the SP of the TWT Agreement negotiated with the one or more second devices 102 arrives; in this way, by keeping the first device 101 in the lower communication mode before the SP of the TWT Agreement arrives and in the higher communication mode within the SP of the TWT Agreement to communicate with the second device 102, the energy consumption of the device can be reduced and the spectrum utilization efficiency can be improved while ensuring the quality of communication service between the first device 101 and the second device 102. Further, for at least one communication parameter, since the communication parameter value of the first device 101 in the second capability communication mode is determined based on the communication parameter value supported by the one or more second devices 102 within the SP of the TWT Agreement; in this way, the communication parameter value supported by the second device 102 can be considered to further avoid unnecessary device energy consumption and waste unnecessary spectrum resources when the first device 101 switches the communication mode while ensuring the quality of communication service between the first device 101 and the second device 102.

[0114] Optionally, the first capability communication mode can also be referred to as a first power mode, a low-energy communication mode, a low-capability communication mode, a low-power communication mode, a lower-capability communication mode, a listening mode, or a low-power communication phase, etc., and the name is not limited in the embodiments of the present disclosure. The second capability communication mode can also be referred to as a high-power mode, a high-energy communication mode, a high-capability communication mode, a high-power communication mode, a higher-capability communication mode, or a high-power communication phase, etc., and the name is not limited in the embodiments of the present disclosure.

[0115] Optionally, the parameter value of a certain device in the first capability communication mode being lower than the parameter value in the second capability communication mode can mean that the communication capability of the device in the first capability communication mode is weaker than the communication capability in the second capability communication mode.

[0116] Optionally, the communication parameters corresponding to the first capability communication mode or the second capability communication mode can include but are not limited to channel bandwidth (Channel BandWidth; BandWidth, abbreviated as BW), supported MCS mode, number of spatial streams (NSS), transmission rate, etc.

[0117] Optionally, in the first capability communication mode, the device supports a channel bandwidth of 20MHz (Mega Hertz) (i.e., BW = 20MHz), a number of SS of 1 (i.e., NSS = 1, single spatial stream), a value of the MCS index of 5 at most (i.e., the value of the MCS index can be any value from 0 to 5, for example, the value of the MCS index is 5, etc.). In the second capability communication mode, the device supports a channel bandwidth greater than or equal to 20MHz, for example, can be any one or more of 40MHz, 80MHz, 160MHz or 320MHz, a number of SS greater than or equal to 2, a value of the MCS index greater than or equal to 5, etc. The specific parameter values can be determined according to the communication parameter values supported by the second device 102 in the SP of the TWT Agreement.

[0118] Optionally, in a communication mode, the MCS information supported by the device is associated with a plurality of communication parameters, for example, the communication parameters associated with the MCS information can include, but are not limited to, at least one of the following: NSS, modulation mode supported by each spatial stream, coding rate, BW, device transmission resource type (for example, resource unit RU, multiple resource unit (MRU), distributed resource unit (dRU), UEQM, etc.), whether the device supports BW punctured channel mode, and punctured channel density supported by the device.

[0119] For example, for each communication parameter, whether the device supports each specific parameter value thereof, for example, for NSS, the maximum NSS supported by the device can be 4, or 8 or 16. For example, for modulation mode, the modulation mode supported by one spatial stream of the device can be at least one of the following: binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), 16-quadrature amplitude modulation (QAM), 64-QAM, 256-QAM, 1024-QAM and 4096-QAM. For example, for coding rate, the coding rate supported by one spatial stream of the device can be 1 / 2, 2 / 3, 3 / 4, 5 / 6. For example, for BW, the BW supported by the device can be at least one of the following: 20MHz, 40MHz, 80MHz, 160MHz and 320MHz. When the device supports BW punctured channel mode, the punctured channel density supported by the device can be at least one of the following: 20MHz, 40MHz, 80MHz, 160MHz, 320MHz.

[0120] For one device, the MCS information supported by the device can refer to Table 1.

[0121] Table 1

[0122] As shown in Table 1, in Table 1, n, n+1, n+2, n+3, n+4, etc. are only examples and are used to identify the difference between each row. The specific values need to be adjusted according to the actual situation. In each row, the corresponding NSS, modulation, coding rate, transmission resource type, BW, whether to support puncturing, and puncturing channel density of the device can be combined at will, and under different combinations, the corresponding MCS index values are different. For example, in the second row, the MCS index values corresponding to different combinations can be t, t+1, t+2, …, etc.

[0123] Optionally, under each communication parameter, the communication parameter value supported by the second device 102 can be the maximum parameter value supported by the second device 102 under the communication parameter.

[0124] As an example, taking the communication parameter including the channel bandwidth as an example, in the case that the operating bandwidth supported by the second device 102 is small and the second device 102 supports receiving or transmitting a large bandwidth PPDU (Physical Layer Protocol Data Unit, i.e. physical layer protocol data unit), the large bandwidth supported by the second device 102 for receiving or transmitting can be determined as the channel bandwidth supported by the second device 102. For example, if the second device 102 is a STA, in the HE Capabilities element of the first wireless frame sent on the STA side, the 20MHz In 160 / 80+80MHz HE PPDU (20Mhz in 160 / 80+80mhz HE PPDU) bit in the HE PHY Capabilities Information field is set to 1. It can be considered that the maximum bandwidth supported by the STA is 160 / 80+80MHz, that is, under the channel bandwidth, the communication parameter value supported by the STA is 160 / 80+80MHz.

[0125] Optionally, in some embodiments, before step 301 (the first device 101 determines the parameter value under the second capability communication mode), the method can further include:

[0126] Step 302, the second device 102 sends a first wireless frame to the first device 101. Accordingly, the first device 101 receives the first wireless frame sent by the second device 102.

[0127] The first wireless frame comprises first identification information, and the first identification information is used to identify a communication parameter value supported by the second device 102 under each communication parameter.

[0128] Optionally, the first wireless frame can comprise one or more of a Probe Request frame, an Association Request frame, a Reassociation Request frame, and an Operating Mode Notification frame.

[0129] Optionally, in some embodiments, the first wireless frame comprises a first element and / or a first field, and the first identification information is carried in the first element and / or the first field.

[0130] The first element comprises at least one of a Capabilities element, an Operation element, and an Operating Mode Notification element; and the first field comprises at least one of an Operating Mode field and an OM Control field (OM: Operating Mode).

[0131] Optionally, in some embodiments, the Capabilities element comprises at least one of an HT Capabilities element (HT: High Throughput), a VHT Capabilities element (VHT: very-High Throughput), an HE Capabilities element (HE: High Efficiency), an EHT Capabilities element (EHT: Extreme High Throughput), and a UHR Capabilities element (UHR: Ultra High Reliability).

[0132] The operation element includes at least one of an HT Operation element, a VHT Operation element, an HE Operation element, an EHT Operation element, and a UHR Operation element.

[0133] Optionally, in some embodiments, the first device 101 can identify the communication parameter values supported by the first device 101 by sending the second device 102 a second wireless frame; wherein the second wireless frame comprises second identification information, and the second identification information is used to identify the communication parameter values supported by the first device 101 under each communication parameter.

[0134] Optionally, the second wireless frame can comprise one or more of a beacon frame, a Probe Response frame, an Association Responnse frame, a Reassociation Response frame, and an Operating Mode Notification frame.

[0135] Optionally, when the first wireless frame contains an Operating Mode field or an Operating Mode Notification element, the first wireless frame can be an Operating Mode Notification frame.

[0136] Optionally, the specific implementation of the second identification information can refer to the first identification information, which is not described here in detail. That is, the second identification information can also be carried in the first element (for example, can comprise at least one of the Capabilities element, the Operation element, and the Operating Mode Notification element) and / or the first field (for example, can comprise at least one of the Operating Mode field and the OM Control field) in the second wireless frame.

[0137] Optionally, in some embodiments, referring to FIG. 3, before step 201 (the first device 101 switches from the first capability communication mode to the second capability communication mode), the method can further comprise:

[0138] Step 301, for each of the communication parameters, the first device 101 determines the communication parameter value in the second capability communication mode according to the minimum value of one or more of the communication parameter values supported by the second devices 102 in the SP of the TWT Agreement.

[0139] Optionally, in the case where the number of the second devices 102 includes one, for each of the communication parameters, the first device 101 can directly determine the communication parameter value supported by the second device 102 in the SP of the TWT Agreement as the communication parameter value of the first device 101 in the second capability communication mode.

[0140] Optionally, in the case where the number of the second devices 102 includes multiple, for each of the communication parameters, the first device 101 can determine the communication parameter value supported by each of the second devices 102 in the SP of the TWT Agreement, and determine the minimum value of the communication parameter values corresponding to all the second devices 102 as the communication parameter value of the first device 101 in the second capability communication mode.

[0141] Optionally, for at least one of the communication parameters, the communication parameter value of the first device 101 in the second capability communication mode is independent in different SPs of the TWT Agreement, and the communication parameter value supported by the second device 102 is also independent. That is, the communication parameter value of the first device 101 in the second capability communication mode and the communication parameter value supported by the second device 102 correspond to the SP of the TWT Agreement one by one.

[0142] Optionally, in some embodiments, in the case where the SP of the TWT Agreement includes multiple, the communication parameter value in the second capability communication mode can be determined by the following way:

[0143] In each of the SPs of the TWT Agreement, for each of the communication parameters, the communication parameter value in the second capability communication mode is determined according to the minimum value of one or more of the communication parameter values supported by the second devices 102 in the SP of the TWT Agreement.

[0144] In other words, assuming that the communication parameter is P, the second devices 102 include device 1, device 2 and device 3, the communication parameter value of device 1 in the communication parameter is P1, the communication parameter value of device 2 in the communication parameter is P2, the communication parameter value of device 3 in the communication parameter is P3, and P1>P3>P2, then in the SP of a certain TWT Agreement negotiated by the first device 101 and the second devices 102, the communication parameter value of the second devices 102 in the communication parameter is P2.

[0145] Optionally, in some embodiments, the second device 102 sleeps outside of its corresponding TWT Agreement's SP, i.e., does not transmit data; the second device 102 stays active and communicates within its corresponding TWT Agreement's SP. However, it is noted that although the second device 102 sleeps outside of its corresponding TWT Agreement's SP, the second device 102 can still contend for the channel and communicate within the successfully contended channel, and thus, the communication parameter values supported by the second device 102 can change before the start time of the TWT Agreement's SP arrives.

[0146] The TWT requesting STA decides which frames to transmit within or outside a TWT SP; and while it is recommended that the TWT requesting STA not transmit using EDCA within or outside TWT SPs, the TWT requesting STA might still do so. If the STA decides to transmit, then the STA might contend for access to the medium as defined in 10.23.2 (HCF contention based channel access (EDCA)) and in 26.2.7 (EDCA operation using MU EDCA parameters).

[0147] The TWT scheduled STA decides which frames to transmit within or outside a TWT SP; and while it is recommended that the TWT scheduled STA not transmit using EDCA within or outside TWT SPs, the TWT scheduled STA might still do so. If the STA decides to transmit, then the STA might contend for accessing the medium as defined in 10.23.2 (HCF contention based channel access (EDCA)) in 26.2.7 (EDCA operation using MU EDCA parameters), and in 35.16 (EPCS priority access).

[0148] While it is recommended that the TWT initiator not transmit using EDCA within or outside TWT SPs, the TWT initiator might still do so. If the TWT initiator decides to transmit, then the TWT initiator might contend for accessing the medium as defined in 10.23.2 (HCF contention based channel access (EDCA)) in 26.2.7 (EDCA operation using MU EDCA parameters), and in 35.16 (EPCS priority access).

[0149] Although the TWT scheduled STA is best not to use EDCA (Enhanced Distributed Channel Access) for data transmission within or outside the TWT SP, the TWT scheduled STA can decide to transmit data within or outside the TWT SP. If the TWT scheduled STA transmits data within or outside the TWT SP, the TWT initiator can compete for the channel according to the channel access based on HCF competition (i.e. EDCA), EDCA operation applying MU EDCA parameters, and medium access defined in EPCS priority access.

[0150] Optionally, in some embodiments, before the start time of the SP of the TWT Agreement arrives, in the case of a change in the communication parameter value supported by the second device 102, the second device 102 needs to re-indicate and change the communication parameter value it supports (for example, by indicating through the Operating Mode field / OM Control field / Operating Mode Notification element in the first wireless frame, etc.), accordingly, the first device 101 can re-determine the communication parameter value of the first device 101 in the second capability communication mode according to the changed communication parameter value supported by the second device 102.

[0151] Optionally, in some embodiments, after step 201 (the first device 101 switches from the first capability communication mode to the second capability communication mode), the method further comprises:

[0152] Step 303, within the SP of the TWT Agreement, the first device 101 exchanges frames with the corresponding one or more second devices 102.

[0153] Optionally, the first device 101 and the one or more second devices 102 can transmit PPDU within the SP of the corresponding TWT Agreement.

[0154] Optionally, in some embodiments, after step 303, the method further comprises:

[0155] Step 304, after the end time of the SP of the TWT Agreement arrives, the first device 101 switches from the second capability communication mode to the first capability communication mode.

[0156] The device power saving management method provided by the embodiments of the present disclosure is described below in conjunction with FIG. 4.

[0157] Referring to FIG. 4, the TWT Scheduling AP includes an AP, the TWT Scheduled STAs include STA1 and STA2, STA1 and STA2 are respectively associated with the AP, STA1 and STA2 participate in the B-TWT Agreement1 and B-TWT Agreement2 initiated by the AP, and there are only two member STAs STA1 and STA2 in the R-TWT Agreement1, and there are only two member STAs STA1 and STA2 in the R-TWT Agreement2. LCM (low current mode, which means a first capability communication mode), HCM (high current mode, which means a second capability communication mode).

[0158] Wherein, STA1 identifies that the maximum channel bandwidth supported by STA1 is 160MHz, and the maximum number of spatial streams supported by STA1 is 6 (hereinafter, the communication parameter value of STA1 under each communication parameter can be referred to as “160MHz / 6”) through the Capabilities element / Operations element carried by the corresponding first wireless frame; STA2 identifies that the maximum channel bandwidth supported by STA2 is 80MHz, and the maximum number of spatial streams supported by STA2 is 4 (hereinafter, the communication parameter value of STA2 under each communication parameter can be referred to as “80MHz / 4”) through the Capabilities element / Operations element carried by the corresponding first wireless frame; and the AP identifies that the maximum channel bandwidth supported by the AP is 320MHz, and the maximum number of spatial streams supported by the AP is 8 (hereinafter, the communication parameter value of the AP under each communication parameter can be referred to as “320MHz / 8”) through the Capabilities element / Operations element carried by the second wireless frame.

[0159] Before the start time of the SP of the B-TWT Agreement 1 (i.e., B-TWT SP1 in FIG. 4) arrives, the AP switches from the first capability communication mode (LCM) to the second capability communication mode (HCM1). In this case, since the minimum of the maximum channel bandwidth is 80MHz and the minimum of the number of spatial streams is 4 among the two members of the B-TWT Agreement 1, the communication parameter values under each communication parameter after the AP switches to the second capability communication mode, i.e., within the SP of the B-TWT Agreement 1, include that the maximum channel bandwidth is 80MHz and the maximum number of supported spatial streams is 4, not that the maximum channel bandwidth is 320MHz and the maximum number of supported spatial streams is 8. Within the SP of the B-TWT Agreement 1, the AP exchanges frames with the STA1 and the STA2, and after the end time of the SP of the B-TWT Agreement 1 arrives, switches from the second capability communication mode (HCM1) to the first capability communication mode (LCM).

[0160] Before the start time of the SP of the B-TWT Agreement 2 arrives, the STA1 changes the communication parameter values of the STA1 under each communication parameter by the Operating Mode field (element) / OM Control field / Operating Mode Notification frame, and notifies (Notify) the changed communication parameter values, which are that the maximum channel bandwidth is 40MHz and the maximum number of supported spatial streams is 2 (i.e., changed from 160MHz / 6 to 40MHz / 2). In this case, since the minimum of the maximum channel bandwidth is 40MHz and the minimum of the maximum number of spatial streams is 2 among the two members of the B-TWT Agreement 2, the communication parameter values under each communication parameter after the AP switches to the second capability communication mode, i.e., within the SP of the B-TWT Agreement 2, include that the maximum channel bandwidth is 40MHz and the maximum number of supported spatial streams is 2. Before the start time of the SP of the B-TWT Agreement 2 (i.e., B-TWT SP1 in FIG. 4) arrives, the AP switches from the first capability communication mode (LCM) to the second capability communication mode (HCM2). Within the SP of the B-TWT Agreement 2, the AP exchanges frames with the STA1 and the STA2, and after the end time of the SP of the B-TWT Agreement 2 arrives, switches from the second capability communication mode (HCM2) to the first capability communication mode (LCM).
