Description

Communication method, site equipment, access point equipment and communication system Technical Field

[0001] The present disclosure relates to the field of communication technology, and in particular to a communication method, a station device, an access point device, and a communication system. Background Art

[0002] With the continuous development of Wi-Fi technology, the next generation of Wi-Fi technology has been proposed: Ultra High Reliability (UHR). In UHR technology, access points (APs) can share transmission opportunity (TXOP) transmission time with other APs. After other APs obtain the transmission time, they can further share it with associated stations (STAs), facilitating non-triggered frame-based (Non-TB) data transmission or peer-to-peer (P2P) data transmission.

[0003] When a STA, as a TXOP holder, is sending uplink data to an associated AP, if the AP needs to transmit temporary / burst low-latency service data to other communication devices, the STA will allocate transmission time from its TXOP to the AP to transmit the temporary / burst low-latency service data. However, this may affect the STA's ability to transmit uplink data to the AP. Therefore, a TXOP handling method is needed to improve the TXOP sharing mechanism and support UHR.

[0036] The embodiments of the present disclosure provide a communication method, a station device, an access point device, and a communication system.

[0037] In a first aspect, an embodiment of the present disclosure provides a communication method, which is performed by a station device STA. The method includes:

[0038] After receiving a reverse transmission opportunity sharing (RTXS) request initiated by an access point device (AP), determining a first radio frame; the first radio frame includes first identification information; the first identification information is used to identify whether the STA extends the obtained transmission opportunity (TXOP);

[0039] The first radio frame is sent.

[0040] In the above embodiment, after receiving the reverse transmission opportunity sharing RTXS request initiated by the access point device AP, the site device determines a first radio frame; carries first identification information through the first radio frame; the first identification information is used to identify whether the STA extends the obtained transmission opportunity TXOP; and sends the first radio frame to the AP. In this way, when the remaining duration of the TXOP is insufficient to transmit the temporary / burst low-latency service data in the RTXS request and the transmission of uplink data from the STA to the AP is completed, the TXOP is extended to ensure that the remaining duration of the (extended) TXOP is sufficient to transmit the temporary / burst low-latency service data in the RTXS request and the transmission of uplink data from the STA to the AP is completed, so as to achieve the goal of giving priority to temporary / burst low-latency service data while ensuring the transmission of interrupted or delayed uplink data, reducing the transmission delay of low-latency service data and improving the data transmission rate.

[0041] In combination with some embodiments of the first aspect, in some embodiments, under a first condition, the first identification information is used to identify the STA to extend the TXOP;

[0042] The first condition includes at least one of the following:

[0043] The first remaining transmission duration in the TXOP is less than or equal to the first transmission duration; wherein the first remaining transmission duration includes the transmission duration remaining in the TXOP when the STA receives the RTXS request; the first transmission duration includes the minimum duration for the AP to complete transmission of low-latency services to other communication devices; the other communication devices include communication devices other than the STA and the AP in the basic service set BSS where the STA and the AP are located;

[0044] The second remaining transmission duration within the TXOP is less than the second transmission duration; wherein, the second remaining transmission duration includes the remaining duration within the TXOP after the AP completes transmitting low-latency service data to other communication devices; the second transmission duration includes the duration of the remaining transmission data of the transmitting STA; the remaining transmission data includes data that the STA has not completed transmitting to the AP when receiving the RTXS request.

[0045] In the above embodiment, when the remaining duration of the TXOP is insufficient to transmit the temporary / burst low-latency service data in the RTXS request and the uplink data transmitted by the STA to the AP, the TXOP is extended to ensure that the remaining duration of the (extended) TXOP is sufficient to transmit the temporary / burst low-latency service data in the RTXS request and the uplink data transmitted by the STA to the AP. This can reduce the transmission delay of the temporary / burst low-latency service data while ensuring the transmission integrity of the uplink data and improving the data transmission rate.

[0046] In combination with some embodiments of the first aspect, in some embodiments, the first identification information is carried in a common information Common Info field of the first radio frame;

[0047] The first identification information is a first parameter value, and the first identification information is used to identify that the STA extends the TXOP; the first radio frame further includes second identification information, and the second identification information is used to identify the extension duration of the TXOP by the STA;

[0048] The first identification information is a second parameter value, and the first identification information is used to identify that the STA does not extend the TXOP.

[0049] In the above embodiment, the first identification information is carried in the Common Info field of the first radio frame to identify whether the STA extends the TXOP. When the STA extends the TXOP, the second identification information carries the STA's extension duration of the TXOP. In this way, whether the STA extends the TXOP and the extension duration when the STA extends the TXOP can be determined based on the specific parameter values ​​of the first identification information and the second identification information, thereby saving signaling overhead.

[0050] In conjunction with some embodiments of the first aspect, in some embodiments, the first radio frame further includes third identification information, where the third identification information is carried in a user information User Info field of the first radio frame; the third identification information is used to identify whether the AP feeds back the first message to the STA within the transmission duration shared by the STA;

[0051] The third identification information is a third parameter value, and the third identification information is used to identify that the AP feeds back a first message to the STA within the transmission duration shared by the STA;

[0052] The third identification information is a fourth parameter value, and the third identification information is used to identify that the AP does not feed back the first message to the STA within the transmission duration shared by the STA;

[0053] The first message is used to indicate that the AP has completed the transmission of low-latency service data to other communication devices.

[0054] In the above embodiment, the first message indicates that the AP has completed the transmission of low-latency service data to other communication devices. By changing the third identification information carried by the first wireless frame to different parameter values ​​according to actual transmission requirements, it is identified whether the AP feeds back the first message to the STA within the transmission time shared by the STA. In this way, when the STA needs to receive the first message fed back by the AP, it can quickly regain the remaining transmission time in the TXOP after receiving the first message, thereby avoiding waste of communication resources.

[0055] In conjunction with some embodiments of the first aspect, in some embodiments, when the third identification information is a third parameter value, a second radio frame is received;

[0056] In which, the STA does not transmit data during the time period between sharing the transmission duration with the AP and receiving the second wireless frame; the second wireless frame includes fourth identification information; the fourth identification information is used to identify that the AP has completed the transmission of low-latency service data to other communication devices.

[0057] In the above embodiment, the fourth identification information indicates that the AP has completed the transmission of low-latency service data to other communication devices. The AP carries the fourth identification information through a second radio frame within the transmission duration shared by the STA, and sends the second radio frame to the STA, indicating that the transmission duration shared by the STA to the AP has ended; in this way, after receiving the first message fed back by the AP, the STA can quickly regain the remaining transmission duration in the TXOP, thereby avoiding waste of communication resources.

[0058] In combination with some embodiments of the first aspect, in some embodiments, the STA does not transmit data within the transmission duration shared with the AP.

[0059] In the above embodiment, by setting the STA not to transmit data during the transmission time shared with the AP, it is possible to avoid interference with data transmission between the AP and other communication devices (for example, the AP sends low-latency service data to the second STA) due to the STA transmitting data during the transmission time shared with the AP.

[0060] In conjunction with some embodiments of the first aspect, in some embodiments,

[0061] The STA sends the remaining transmission data to the AP within a third remaining transmission duration; wherein the third remaining transmission duration includes the remaining duration in the extended TXOP after the AP completes transmitting the low-latency service data to other communication devices;

[0062] or

[0063] The STA sends the remaining transmission data to the AP within the second remaining transmission duration.

[0064] In the above embodiment, after the AP completes transmitting low-latency service data to other communication devices, the STA re-holds the TXOP and continues to transmit the remaining transmission data to the AP within the re-held TXOP. In this way, within the (extended) TXOP, while giving priority to transmitting temporary / burst low-latency service data between the AP and other communication devices, the STA's own UL (up link) data transmission can be guaranteed, thereby reducing the transmission delay of the low-latency service data, increasing the data transmission rate, ensuring the integrity of the data transmission, and improving resource utilization efficiency.

[0070] The second remaining transmission duration within the TXOP is less than the second transmission duration; wherein, the second remaining transmission duration includes the remaining duration within the TXOP after the AP completes transmitting low-latency service data to other communication devices; the second transmission duration includes the duration of transmitting the remaining transmission data of the STA; the remaining transmission data includes data that the STA has not completed transmitting to the AP when receiving the RTXS request.

[0114] As shown in FIG1 , a communication system 100 includes a station device (STA) 101 and a second access point device (AP) 102 .

[0115] In some embodiments, the station device 101 includes, for example, a wireless communication chip, a wireless sensor, or a wireless communication terminal that supports Wi-Fi communication. Optionally, the wireless communication terminal is, for example, at least one of a mobile phone, a wearable device, an Internet of Things device that supports Wi-Fi communication, a car with WiFi communication, a smart car, a tablet computer, a computer with wireless transceiver function, 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, but is not limited thereto.

[0116] Specifically, the station device 101 may be a terminal device or a network device equipped with a wireless fidelity (Wi-Fi) 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.

[0117] In some embodiments, the access point device 103 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.

[0118] 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.

[0119] 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.

[0120] 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.

[0121] The various embodiments of the present disclosure can be applied to a wireless local area network (WLAN), such as a local area network that adopts the 802.11 series of protocols. In a WLAN, a basic service set (BSS) is a basic component of a WLAN. A BSS network is composed of station devices with certain associations 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 with a dedicated BSS management function, which is called an access point device, and other stations in the BSS network that are not APs are called terminals, also called non-AP STAs. APs 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, etc., a STA cannot detect other STAs that are farther away from it, and the two are hidden nodes of each other.

[0122] FIG2 is one of the interactive schematic diagrams of the communication method according to an embodiment of the present disclosure. As shown in FIG2 , the method includes:

[0123] In step 201, after receiving a reverse transmission opportunity sharing (RTXS) request from an access point device AP102, the station device STA101 determines a first radio frame; the first radio frame includes first identification information; the first identification information is used to identify whether STA101 extends the obtained transmission opportunity TXOP.

[0124] Optionally, the first wireless frame may include a MU-RTS TXS Trigger frame (multi-user request to send transmission opportunity sharing trigger frame; RTS, Request to Send, request to send frame; MU-RTS, Multi-user Request to Send, multi-user request to send; Trigger frame, trigger frame) or a modified frame of the MU-RTS TXS Trigger frame.

[0125] Optionally, the reverse transmission opportunity sharing (RTXS) request initiated by the AP 102 may include a first duration required for the AP 102 to perform low-latency service transmission with other communication devices.

[0126] In some embodiments, under a first condition, the first identification information is used to identify the STA 101 to extend the TXOP;

[0127] The first condition includes at least one of the following:

[0128] The first remaining transmission duration in the TXOP is less than or equal to the first transmission duration; wherein the first remaining transmission duration includes the transmission duration remaining in the TXOP when the STA 101 receives the RTXS request; the first transmission duration includes the minimum duration for the AP 102 to complete the transmission of the low-latency service to other communication devices; the other communication devices include communication devices other than the STA and the AP in the basic service set BSS where the STA and the AP are located;

[0129] The second remaining transmission duration within the TXOP is less than the second transmission duration; wherein, the second remaining transmission duration includes the remaining duration within the TXOP after the AP102 completes transmitting low-latency service data to other communication devices; the second transmission duration includes the duration of transmitting the remaining transmission data of STA101; the remaining transmission data includes the data that the STA101 has not completed transmitting to the AP102 when receiving the RTXS request.

[0130] Optionally, other communication devices may include any STA (hereinafter referred to as "second STA") in the basic service set BSS where the STA and the AP are located, except the STA and the AP.

[0131] Optionally, the first transmission duration includes at least the duration required for STA101 to send the third wireless frame, the duration required for AP102 to send an RTS frame (Request to Send) to other communication devices, the duration required for other communication devices to send a CTS frame (Clear to Send) to AP102, the first duration required for AP102 to perform low-latency service transmission with other communication devices, and the sum of four short interframe space (SIFS) durations.

[0132] The first remaining transmission duration is less than or equal to the first transmission duration, that is, the first remaining duration is insufficient to be shared with the minimum duration for AP 102 to complete the transmission of the low-latency service to other communication devices.

[0133] Optionally, the remaining transmission data specifically includes data that is cached locally in the STA101 when the STA101 receives the RTXS request and transmitted to the AP102.

[0134] The second remaining transmission duration in TXOP is less than the second transmission duration, that is, after STA101 shares with AP102 the minimum duration used to complete the transmission of low-latency services to other communication devices, the remaining transmission duration in the first remaining duration is not sufficient to ensure that STA101 completes the transmission of the remaining transmission data.

[0135] In the above embodiment, when the remaining duration of the TXOP is insufficient to transmit the temporary / burst low-latency service data in the RTXS request and complete the transmission of the uplink data transmitted by STA101 to AP102, the TXOP is extended to ensure that the remaining duration of the (extended) TXOP is sufficient to transmit the temporary / burst low-latency service data in the RTXS request and complete the transmission of the uplink data transmitted by STA101 to AP102. This can reduce the transmission delay of the temporary / burst low-latency service data while ensuring the transmission integrity of the uplink data and improving the data transmission rate.

[0136] In some embodiments, the first identification information is carried in a Common Info field of the first radio frame;

[0137] The first identification information is a first parameter value, and the first identification information is used to identify that the STA 101 extends the TXOP; the first radio frame also includes second identification information, and the second identification information includes the extension duration of the TXOP by the STA 101;

[0138] The first identification information is a second parameter value, and the first identification information is used to identify that the STA101 does not extend the TXOP.

[0139] In the disclosed embodiment, setting a TXOP extension duration in the first radio frame is optional. When STA 101 needs to extend the TXOP, the first radio frame includes second identification information, and the second identification information is used to identify the TXOP extension duration selected by STA 101. When STA 101 does not need to extend the TXOP, the field corresponding to the second identification information in the first radio frame may be a reserved bit, i.e., the field corresponding to the second identification information may not be set.

[0140] Optionally, when the duration of the TXOP is T1 and the extended duration of the TXOP is T2, the extended duration of the TXOP is T1+T2.

[0141] The frame format of the MU-RTS TXS Trigger frame can be seen in Table 1:

[0142] Table 1:

[0143] Referring to Table 1, the MU-RTS TXS Trigger frame may include a Common Info field, a User Info field, and a first identification field, etc., wherein the first identification field occupies one byte in the MU-RTS TXS Trigger frame, and the second identification information can be carried through the first identification field (TXOP extension field).

[0144] The format of the Common info field can be found in Table 2:

[0145] Table 2:

[0146] Referring to Table 2, the first identifier occupies 1 bit in the Common Info field, and the first identifier information can be carried by the first identifier (TXOP extension requirement identifier).

[0147] As an example, the first parameter value can be set to 1 and the second parameter value can be set to 0. That is, when the first identification information is 1, it is used to indicate that STA101 extends the TXOP, and the second identification information is used to indicate the extension duration of the TXOP by STA101. When the first identification information is 0, it is used to indicate that STA101 does not extend the TXOP.

[0148] In the above embodiment, the first identification information and the second identification information are carried through the Common Info field of the first wireless frame to identify whether the STA101 extends the TXOP and the extension duration when STA101 extends the TXOP; in this way, whether STA101 extends the TXOP and the extension duration when STA101 extends the TXOP can be determined through the specific parameter values ​​of the first identification information and the second identification information, thereby saving signaling overhead.

[0149] In some embodiments, the first radio frame further includes third identification information, the third identification information being carried in a user information User Info field of the first radio frame; the third identification information being used to identify whether the AP 102 feeds back the first message to the STA 101 within the transmission duration shared by the STA 101;

[0150] The third identification information is a third parameter value, and the third identification information is used to identify that the AP 102 feeds back a first message to the STA 101 within the transmission duration shared by the STA 101;

[0151] The third identification information is a fourth parameter value, and the third identification information is used to identify that the AP 102 does not feed back the first message to the STA 101 within the transmission duration shared by the STA 101;

[0152] The first message is used to indicate that the AP 102 has completed the transmission of low-latency service data to other communication devices.

[0153] The format of the User Info field can be found in Table 3:

[0154] Table 3:

[0155] Referring to Table 3, the second identifier occupies 1 bit in the User Info field, and the third identification information can be carried by the second identifier (TXS transmission end notification requirement identifier).

[0156] As an example, the third parameter value can be set to 1 and the fourth parameter value can be set to 0. That is, when the third identification information is 1, it indicates that AP102 feeds back the first message to STA101 within the transmission duration shared by STA101. When the third identification information is 0, it indicates that AP102 does not feed back the first message to STA101 within the transmission duration shared by STA101.

[0157] Optionally, the first message is specifically used to indicate that AP102 has completed the transmission of low-latency service data to other communication devices (eg, a second STA) within the transmission duration shared by STA101.

[0158] In the above embodiment, the first message indicates that AP102 has completed the transmission of low-latency service data to other communication devices. By changing the third identification information carried by the first wireless frame to different parameter values ​​according to actual transmission requirements, it is identified whether AP102 feeds back the first message to STA101 within the transmission time shared by STA101; in this way, when STA101 needs to receive the first message fed back by AP102, it can re-hold the remaining transmission time in TXOP as soon as possible after receiving the first message, thereby avoiding waste of communication resources.

[0159] In some embodiments, the STA 101 does not transmit data during the transmission duration shared with the AP 102 .

[0160] Optionally, regardless of whether the third identification information is the third parameter value or the fourth parameter value, that is, regardless of whether AP102 feeds back the first message to STA101 within the transmission time shared by STA101, STA101 does not transmit data within the transmission time shared with the AP102.

[0161] In the above embodiment, by setting STA101 not to transmit data within the transmission time shared with the AP102, it is possible to avoid interference with data transmission between AP102 and other communication devices (for example, AP102 sending low-latency service data to the second STA) caused by STA101 transmitting data within the transmission time shared with AP102.

[0162] Step 202 : STA 101 sends the first wireless frame to AP 102 .

[0163] In an embodiment of the present disclosure, after receiving a reverse transmission opportunity sharing RTXS request initiated by an access point device AP102, a site device determines a first wireless frame; the first identification information is carried by the first wireless frame; the first identification information is used to identify whether STA101 extends the obtained transmission opportunity TXOP; in this way, when the remaining duration of the TXOP is insufficient to transmit the temporary / burst low-latency service data in the RTXS request and complete the transmission of uplink data from STA101 to AP102, the TXOP is extended to ensure that the remaining duration of the (extended) TXOP is sufficient to transmit the temporary / burst low-latency service data in the RTXS request and complete the transmission of uplink data from STA101 to AP102, which can reduce the transmission delay of the temporary / burst low-latency service data while ensuring the transmission integrity of the uplink data and improving the data transmission rate.

[0164] Optionally, in some embodiments, referring to FIG3 , if the first identification information is a first parameter value, that is, the first identification information is used to identify the STA 101 to extend the TXOP, then after receiving the first radio frame, the other STAs maintain the current NAV (Network Allocation Vector), that is, there is no need to update the NAV set by the other STAs according to the TXOP. If the first identification information is a second parameter value, that is, the first identification information is used to identify the STA 101 not to extend the TXOP, then after receiving the first radio frame, the other STAs need to update the NAV of the other STAs according to the extended TXOP (that is, the original TXOP + the extended duration, the duration obtained).

[0165] Among them, other STAs include STAs in the basic service set BSS where STA101 and AP102 are located, except for the STA101 and the second STA that needs to perform low-latency service transmission with AP102.

[0166] In the above embodiment, the NAV of other STAs is updated in real time according to the (extended) TXOP, so that other STAs are busy within the (extended) TXOP; in this way, it is possible to avoid interference caused by other STAs communicating within the (extended) TXOP with other communication devices, such as data transmission between AP102 and other communication devices (for example, AP102 sends low-latency service data to the second STA), and communication processes such as STA101 sending uplink data to AP102.

[0167] Step 203: When the third identification information is a third parameter value, the AP 102 determines a second radio frame;

[0168] Among them, the STA101 does not transmit data during the time period between sharing the transmission duration with the AP102 and receiving the second wireless frame; the second wireless frame includes fourth identification information; the fourth identification information is used to identify that the AP102 has completed the transmission of low-latency service data to other communication devices.

[0169] Optionally, STA101 does not transmit data during the time period between sharing the transmission duration with the AP102 and receiving the second wireless frame, that is, after receiving the RTXS request sent by AP102, STA101 suspends / postpones transmitting uplink data to AP102.

[0170] Step 204 : AP 102 sends the second wireless frame to STA 101 .

[0171] In the above embodiment, the fourth identification information indicates that AP102 has completed the transmission of low-latency service data to other communication devices. AP102 carries the fourth identification information through the second wireless frame within the transmission duration shared by STA101, and sends the second wireless frame to STA101, indicating that the transmission duration shared by STA101 to AP102 has ended; in this way, STA101 can regain the remaining transmission duration in TXOP as soon as possible after receiving the first message fed back by AP102, thereby avoiding waste of communication resources.

[0172] Step 205: If the STA101 has not completed the transmission of the remaining transmission data to the AP102 when receiving the RTXS request, that is, the STA101 suspends / postpones the transmission of the remaining transmission data to the AP102, then after the AP102 completes the transmission of low-latency service data to other communication devices, the STA101 continues to transmit the remaining transmission data to the AP102.

[0173] Optionally, step 205 may include step 2051 or step 2052 .

[0174] In step 2051, the STA101 sends the remaining transmission data to the AP102 within a third remaining transmission duration; wherein, the third remaining transmission duration includes the remaining duration within the extended TXOP after the AP102 completes transmitting the low-latency service data to other communication devices.

[0175] Optionally, the third remaining transmission duration is the first remaining transmission duration + the extended duration - the transmission duration shared by STA 101 to AP 102. Optionally, the second identification information is used to identify the extended duration of the TXOP by the STA.

[0176] Step 2052: The STA 101 sends the remaining transmission data to the AP 102 within the second remaining transmission duration.

[0177] In the above embodiment, after AP102 completes transmitting low-latency service data to other communication devices, STA101 re-holds the TXOP and continues to transmit the remaining transmission data to AP102 within the re-held TXOP; in this way, within the (extended) TXOP, while giving priority to AP102 transmitting temporary / burst low-latency service data with other communication devices, the transmission of STA101's own UL (up link) data can be guaranteed, thereby reducing the transmission delay of the low-latency service data, increasing the data transmission rate, ensuring the integrity of the data transmission, and improving resource utilization efficiency.
