[0092] The embodiments of the present disclosure provide a device power saving management method, a communication device, and a communication system.
[0093] FIG1 is a schematic diagram showing the architecture of a communication system according to an embodiment of the present disclosure.
[0094] As shown in Figure 1, a communication system 100 includes communication devices, which may be station devices (STA) 101 and access point devices (AP) 102. For ease of description, the communication devices are exemplified as the first device and / or the second device.
[0095] In some embodiments, the site device 101 includes, for example, a wireless communication chip, a wireless sensor, or a wireless communication terminal that supports WiFi communication. Optionally, the wireless communication terminal includes, but is not limited to, at least one of a mobile phone, a wearable device, an Internet of Things device that supports WiFi communication, a car with WiFi communication, a smart car, a tablet computer, a computer with wireless transceiver capabilities, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device used in industrial control, a wireless terminal device used in self-driving, a wireless terminal device used in remote medical surgery, a wireless terminal device used in a smart grid, a wireless terminal device used in transportation safety, a wireless terminal device used in a smart city, and a wireless terminal device used in a smart home.
[0096] Specifically, the station device 101 may be a terminal device or network device equipped with a wireless fidelity (WiFi) chip. Optionally, the station device 101 may support multiple WLAN standards, such as 802.11ax, 802.11be, 802.11ac, 802.11n, 802.11g, 802.11b, 802.11a, 802.11bf, and 802.11bn, as well as the next generation 802.11 protocol, but is not limited thereto.
[0097] In some embodiments, the access point device 102 can be an access point for a mobile terminal to enter a wired network. The AP is equivalent to a bridge connecting a wired network and a wireless network. Its main function is to connect various wireless network clients together and then connect the wireless network to the Ethernet. Specifically, 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 and 802.11a, 802.11bf, 802.11bn, and support the next generation 802.11 protocol, but is not limited to this.
[0098] Optionally, in an embodiment of the present disclosure, the AP and STA may be devices supporting multiple connections, for example, they may be represented as a multi-connection access point device (AP MLD) and a multi-connection site device (Non-Access Point Multi-Link Device, Non-AP MLD), respectively; the AP MLD may represent an access point supporting multi-connection communication functions, and the non-AP MLD may represent a site supporting multi-connection communication functions.
[0099] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.
[0100] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or a portion thereof, but are not limited thereto. The entities shown in FIG1 are illustrative only. The communication system may include all or part of the entities shown in FIG1 , or may include other entities outside of FIG1 . The number and form of the entities are arbitrary, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.
[0101] The various embodiments of the present disclosure can be applied to wireless local area networks (WLANs), such as those using the 802.11 series of protocols. In a WLAN, a Basic Service Set (BSS) is a fundamental component of a WLAN. A BSS network consists of station devices with some association within a specific coverage area. One scenario of association is that stations communicate directly with each other in an ad hoc network, which is called an Independent Basic Service Set (IBSS). Another more common scenario is that in a BSS network, there is only one central station dedicated to managing the BSS, called an access point, and all other STAs in the network are associated with it. Other stations in the BSS network that are not the central station are called terminals, also called non-AP STAs. Terminals and non-AP STAs are collectively referred to as STAs. When describing STAs, there is no need to distinguish between APs and non-AP STAs. In the same BSS network, due to distance, transmission power, and other factors, a STA cannot detect other STAs that are farther away from it, and the two STAs are each other's hidden nodes.
[0102] FIG2 is a schematic diagram of a device power saving management method according to an embodiment of the present disclosure. As shown in FIG2 , the method includes:
[0103] In step 201, the first device sends a data frame in a secondary channel with the second device; wherein the first identification bit of the data frame is set to a first parameter value, and the second identification bit is set to a second parameter value, indicating that after the first device receives an ACK frame replied by the second device on the secondary channel, it switches to the primary channel with the second device and enters a sleep state on the primary channel.
[0104] In WLAN, channels are typically divided into primary channels and secondary channels (also known as auxiliary channels or non-primary channels). A secondary channel can contain one or more sub-channels. For example, if the basic bandwidth unit is 20 MHz, when the channel bandwidth is 20 MHz, there is only one primary channel with a bandwidth of 20 MHz. When the channel bandwidth is greater than 20 MHz, there is one channel with a bandwidth of 20 MHz as the primary channel, and the remaining one or more 20 MHz channels are secondary channels. The primary 20 MHz channel is the common channel of operation for stations that are members of the basic service set (BSS). Stations in the BSS can compete for channels on the primary 20 MHz channel to seize channel resources.
[0105] As an example, as shown in FIG3 , the primary channel is, for example, the primary 20 MHz channel in FIG3 ; wherein the secondary channel may include one or more sub-channels, for example, the 20 MHz secondary channel and the 40 MHz secondary channel in FIG3 .
[0106] During the channel contention process, if the primary channel is in the OBSS busy state (OBSS interference), as shown in the T1 and T2 time periods in the figure, for example, it is occupied by other devices in the same OBSS as the WLAN, and other devices send physical layer protocol data units (PPDUs) on the primary channel, then the primary channel is in the OBSS busy state. If the primary channel is in the OBSS busy state, in order to fully utilize the channel resources, it can be switched to a secondary channel for communication to improve the communication system throughput and maximize channel resource utilization. For example, in the T1 time period, it can switch to a 20MHz secondary channel for communication, or in the T2 time period, it can switch to a 40MHz secondary channel for communication.
[0107] If the primary channel is in an idle state, as shown in the T3 time period in the figure, the AP and STA can send PPDUs to each other.
[0108] In addition, when communication is performed on the primary channel (the secondary channel is busy), when the secondary channel is idle, the primary and secondary channels can be aggregated for communication to improve the system throughput.
[0109] In an embodiment of the present disclosure, within an OBSS transmission opportunity (TXOP) sensed by a primary channel, a first device sends a data frame in a secondary channel with a second device; wherein the first identification bit may be a power management (PM) identification bit of the data frame, and the first parameter value may be set to 1, and the PM identification bit is set to 1, indicating that the first device will enter a power management (PM) mode; the second identification bit of the data frame is set to a second parameter value, and the second identification bit may be a more data identification bit, and the second parameter value may be 0, indicating that the first device has no data to continue sending.
[0110] Optionally, the PM flag and / or the more data flag may be set in a frame header of a media access control layer (MAC) of the data frame.
[0111] It is understood that the first flag is used to identify whether the first device has entered power saving mode. The first flag can also be identified by a flag other than the PM flag. The second flag is used to identify whether the first device has data to continue sending. The second flag can also be identified by a flag other than the more data flag. This is not limited in the present embodiment. For ease of explanation, the following examples will only use the first flag as the PM flag and the second flag as the more data flag. This does not constitute a limitation on the specific content of the first flag and the second flag.
[0112] Among them, the first device sends the data frame, and jointly indicates through the PM flag and the more data flag of the data frame that the first device will switch to the main channel and enter the sleep state on the main channel after receiving the ACK frame fed back by the second device on the secondary channel; in this way, the PM flag and the more data flag of the data frame are used on the secondary channel to realize the negotiation of the sleep state (or power saving mode) after switching back to the main channel.
[0113] After the first device switches back to the main channel, it enters the sleep state without having to negotiate the switch back to the sleep state after the main channel through other message frames; in this way, on the one hand, if the aforementioned message frame needs to be sent again, the first device needs to compete for channel resources on the main channel again to transmit the message frame, which may cause communication conflicts with other communication devices; on the other hand, transmitting the message frame causes a waste of resources.
[0114] In some embodiments, after step 201, steps 202 to 205 are also included.
[0115] Step 202: The first device receives an ACK frame replied by the second device on the secondary channel.
[0116] After the first device sends the data frame, it receives an acknowledgment (ACK) frame fed back by the second device on the secondary channel; the ACK frame indicates that the second device successfully receives the data frame.
[0117] Step 203: The first device switches to the primary channel with the second device.
[0118] The first device sends the data frame and, after receiving an ACK frame fed back by the second device on the secondary channel, the first device completes data transmission on the secondary channel and switches to the primary channel.
[0119] In some embodiments, the first device and the second device negotiate secondary channel information after initial association; the secondary channel information includes a listening period of the secondary channel.
[0120] in,
[0121] In some embodiments, switching to the primary channel with the second device includes:
[0122] The first device switches to the primary channel with the second device, and enters a dormant state in the primary channel after a Medium Synchronization delay time and / or a switching time delay, so as to quickly enter a power saving state.
[0123] In some embodiments, the method further comprises:
[0124] The first device and the second device have pre-negotiated a listening period of the secondary channel. Then, before the listening moment of the listening period arrives, the first device enters a dormant state on the secondary channel.
[0125] For example, during the initial association process, the first device and the second device pre-negotiate the listening period of the secondary channel. Before the listening moment of the listening period arrives, even if the secondary channel is activated, the first device still enters a dormant state on the secondary channel.
[0126] It should be noted that, in the embodiment of the present disclosure, the execution order of step 204 and step 205 is not particular.
[0127] Step 204: Entering a dormant state on the primary channel.
[0128] The negotiation of the dormant state (or power saving mode) after switching back to the primary channel is achieved through the PM flag and the more data flag of the data frame in the secondary channel.
[0129] After the first device switches back to the primary channel, it enters the sleep state without having to negotiate the sleep state after switching back to the primary channel through other message frames.
[0130] Step 205: The first device determines whether to enter a dormant state on the secondary channel according to the listening period of the secondary channel negotiated with the second device.
[0131] After the first device switches back to the primary channel, it can determine whether to enter the dormant state on the secondary channel according to the listening period of the secondary channel pre-negotiated with the second device.
[0132] In some embodiments, the first device determines whether to enter a dormant state on the secondary channel according to a listening period of the secondary channel negotiated with the second device, including:
[0133] The negotiated listening period of the secondary channel is greater than 0 milliseconds, and before the listening moment of the listening period arrives, the first device enters a dormant state on the secondary channel;
[0134] or
[0135] The negotiated listening period of the secondary channel is equal to 0 milliseconds, and the awake state is maintained in the secondary channel.
[0136] Among them, if the listening period of the secondary channel pre-negotiated by the first device and the second device is greater than 0 milliseconds, for example, 2.7 milliseconds, then before the listening time of the listening period arrives, the first device enters a sleep state on the secondary channel; if the negotiated listening period of the secondary channel is equal to 0 milliseconds, then the first device remains awake in the secondary channel and keeps listening.
[0137] Referring to FIG4 , FIG4 is a schematic diagram of a device power saving management method according to an embodiment of the present disclosure. As shown in FIG2 , the method includes:
[0138] Step 401: A first device sends a data frame in a secondary channel with a second device.
[0139] After step 401, step 402 or step 403 is executed.
[0140] In step 402, the first flag bit of the data frame is set to a first parameter value (for example, the PM bit is set to 1), and the second flag bit is set to a second parameter value (for example, the more data flag bit is set to 0), indicating that after the first device receives the ACK frame replied by the second device on the secondary channel, it switches to the main channel with the second device and enters a sleep state on the main channel.
[0141] After step 402 , at least one of steps 202 to 205 may be executed.
[0142] In step 403, the first identification bit of the data frame is set to the third parameter value (for example, the PM bit is set to 0), and the second identification bit is set to the fourth parameter value (for example, the more data identification bit is set to 1), then the first device can execute step 404 and / or step 405.
[0143] Among them, the third parameter value is, for example, 0, indicating that the first device does not enter the power management (PM) mode; for example, the PM bit in the MAC frame header of the last frame of the data frame transmitted in the secondary channel is set to 0, indicating that the first device does not enter the PM mode; the second identification bit of the data frame is set to the fourth parameter value, and the fourth parameter value is, for example, 0, indicating that the first device STA has more data frames to send after sending the data frame.
[0144] Step 404: The first device determines whether to enter a dormant state on the secondary channel according to the listening period of the secondary channel negotiated with the second device.
[0145] In the secondary channel, the first device determines whether to enter a dormant state in the secondary channel according to a listening period of the secondary channel negotiated with the second device.
[0146] In step 405 , the first device switches to the primary channel and accesses the primary channel through an enhanced distributed channel access (EDCA) mechanism after the Medium Synchronization delay time and / or the switching time delay.
[0147] The first device switches to the primary channel, and in the primary channel, after the Medium Synchronization delay time and / or the switching time delay, accesses the primary channel through the Enhanced Distributed Channel Access (EDCA) mechanism and attempts to continue sending data frames.
[0148] In some embodiments, step 404 includes:
[0149] The negotiated listening period of the secondary channel is greater than 0 milliseconds, and before the listening moment of the listening period arrives, the first device enters a dormant state on the secondary channel;
[0150] or
[0151] The negotiated listening period of the secondary channel is equal to 0 milliseconds, and the awake state is maintained in the secondary channel.
[0152] Among them, if the listening period of the secondary channel pre-negotiated by the first device and the second device is greater than 0 milliseconds, for example, 2.7 milliseconds, then before the listening time of the listening period arrives, the first device enters a sleep state on the secondary channel; if the negotiated listening period of the secondary channel is equal to 0 milliseconds, then the first device remains awake in the secondary channel and keeps listening.
[0153] In some embodiments, step 405 includes:
[0154] After accessing the primary channel through the EDCA mechanism, the method includes:
[0155] sensing that the primary channel is idle, and transmitting a data frame on the primary channel;
[0156] or
[0157] If the primary channel is perceived to be busy, the secondary channel is switched to communicate at the listening time of the listening period of the secondary channel; or data frames are transmitted on the primary channel through the EDCA mechanism competing channel.
[0158] After the first device accesses the primary channel through the EDCA mechanism, it sends a message when the primary channel is in an awake state and senses that the channel is idle.
[0159] If the channel is perceived to be busy, it switches to the secondary channel for communication after the secondary channel listening period arrives; or it competes for the channel through the EDCA mechanism on the primary channel for transmission.
[0160] In an embodiment of the present disclosure, a first device sends a data frame on a secondary channel, and the PM flag and the more data flag of the data frame jointly indicate that the first device will switch to the main channel and enter a sleep state on the main channel after receiving an ACK frame fed back by the second device on the secondary channel; in this way, the PM flag and the more data flag of the data frame on the secondary channel are used to negotiate the sleep state (or power saving mode) after switching back to the main channel, thereby improving the communication mechanism of the WLAN device on the main and secondary channels to meet the transmission requirements of the UHR.
