[0132] 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.
[0133] 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.
[0134] 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.
[0135] FIG2 is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2 , the method includes:
[0136] In step 201, a first site device determines a TDLS Setup Request frame; the TDLS Setup Request frame includes first identification information, where the first identification information identifies the first site device's support capability information for the P2P TXS mode; the support capability information includes: whether the first site device supports the P2P transmission opportunity sharing TXS mode, and at least one of the types of P2P TXS modes supported by the first site device.
[0137] In WLAN communication, reducing the transmission delay of low-latency communication services is one of the main research goals. For deterministic or periodic low-latency services, the Restricted-Target Wake Time (R-TWT) mechanism can effectively ensure the timely transmission of low-latency communication services. However, when the AP or STA faces some temporary or sudden low-latency services, the R-TWT mechanism is no longer applicable. Therefore, in the embodiment of the present disclosure, during the process of establishing a Tunneled Direct Link Setup (TDLS) link between a first site device and a second site device, the first site device determines a TDLS Setup Request frame and carries first identification information in the TDLS Setup Request frame. The first identification information identifies the first site device's support capability information for the P2P TXS mode, thereby realizing P2P TXS mode support capability interaction with the TDLS device.
[0138] Two TDLS devices that have established a TDLS link can communicate directly over the TDLS link. P2P TXS mode refers to the point-to-point (P2P) transmission opportunity sharing (TXS) mode. For example, a TXOP holder can trigger the TXS process to allocate part of its reserved TXOP time to other devices. These other devices then use the allocated TXOP to promptly send low-latency services to the receiving device.
[0139] The first site device's support capability information for the P2P TXS mode includes at least one of the following:
[0140] Whether the first site device supports the P2P transmission opportunity sharing (TXS) mode, and the type of the P2P TXS mode supported by the first site device.
[0141] Among them, whether the first site device supports the P2P transmission opportunity sharing TXS mode, that is, whether the first site device supports the P2P TXS mode; the type of P2P TXS mode supported by the first site device, for example, whether the first site device supports actively initiating the P2P TXS mode, or the first site device supports responding to the P2P TXS mode initiated by other devices.
[0142] Typically, within a TXOP, only the TXOP holder can actively send data; other devices can only receive data or send response frames (e.g., ACK frames) for the data they receive. For example, when the first station device is a STA and, as the TXOP holder, is sending data (uplink data or P2P data) to a second station device (the AP that establishes an initial association with the STA, or the STA that establishes a P2P link with the STA), if the second station device has temporary / burst low-latency communication services to transmit to other communication devices, it can use the transmission time allocated to it by the first station device through the P2P TXS mode to transmit the temporary / burst low-latency communication services, thereby ensuring the transmission of low-latency services. This eliminates the need for the second station device to wait until the TXOP held by the first station device ends before it has the opportunity to transmit the temporary / burst low-latency communication services, resulting in higher transmission latency.
[0143] In the disclosed embodiments, during the TDLS link establishment process, a TDLS device notifies the other party of its support for the P2P TXS mode through first identification information. Later in the communication process, if a bursty / temporary low-latency communication service is encountered by the TXOP responder (the second site device), and the TXOP holder (the first site device) supports inter-site transmission opportunity sharing and has the ability to share with other devices, the TXOP responder can send a transmission opportunity sharing request to obtain a transmission opportunity. The methods provided in the disclosed embodiments can effectively address bursty low-latency services, further improve the low-latency transmission mechanism, and reduce the transmission delay of low-latency communication services.
[0144] Step 202: The first site device sends the TDLS Setup Request frame.
[0145] The first site device sends the TDLS Setup Request frame, and notifies the other party of its own support capability information for the P2P TXS mode by carrying the first identification information in the TDLS Setup Request frame.
[0146] In some embodiments, the TDLS Setup Request frame includes a UHR Capabilities element;
[0147] The first identification information is carried in a P2P TXOP Sharing mode support (Mode Support) identification field of the UHR capability element.
[0148] The first identification information is included in the UHR capability element.
[0149] For example, the first identification information may be carried in the P2P TXOP Sharing Mode Support identification field, and is used to identify whether the device sending the TDLS Setup Request frame supports the P2P TXS mode and the type of support.
[0150] In some embodiments, the first identification information includes at least one of the following situations 1 to 4:
[0151] In case one, the first identification information is set to the first parameter value, indicating that the first site device supports the ability to initiate TXS to the TDLS device, and supports the ability to respond to TXS initiated by other TDLS devices; for example, when the first parameter value is set to 3, it indicates that the device sending the TDLS Setup Request frame (the first site device) has the ability to initiate TXS to other TDLS devices, and has the ability to respond to TXS initiated by other TDLS devices.
[0152] In case two, the first identification information is set to the second parameter value, indicating that the first site device supports the ability to initiate TXS to the TDLS device, and does not support the ability to respond to TXS initiated by other TDLS devices; for example, when the second parameter value is set to 2, it indicates that the device (first site device) sending the TDLS Setup Request frame has the ability to initiate TXS to other TDLS devices, but does not have the ability to respond to TXS initiated by other TDLS devices.
[0153] Case three, the first identification information is set to the third parameter value, indicating that the first site device does not support the ability to initiate TXS to the TDLS device, and supports the ability to respond to TXS initiated by other TDLS devices; for example, when the third parameter value is set to 1, it indicates that the device (first site device) sending the TDLS Setup Request frame does not have the ability to initiate TXS to other TDLS devices, but has the ability to respond to TXS initiated by other TDLS devices.
[0154] Case four, the first identification information is set to the fourth parameter value, indicating that the first site device does not support the ability to initiate TXS to the TDLS device, and does not support the ability to respond to TXS initiated by other TDLS devices; for example, when the fourth parameter value is set to 0, it indicates that the device (first site device) sending the TDLS Setup Request frame does not have the ability to initiate TXS to other TDLS devices, and does not have the ability to respond to TXS initiated by other TDLS devices.
[0155] Step 203: The second site device sends a TDLS Setup Response frame.
[0156] The TDLS Setup Response frame includes second identification information, where the second identification information identifies the second site device's support capability information for the P2P TXS mode; the support capability information includes: whether the second site device supports the P2P transmission opportunity sharing TXS mode, and at least one of the types of P2P TXS modes supported by the second site device.
[0157] The TDLS Setup Response frame is used to respond to the TDLS Setup Request frame. After receiving the TDLS Setup Request frame from the first site device, the second site device sends a TDLS Setup Response frame to the first site device. The TDLS Setup Response frame includes second identification information, which is used to identify whether the second site device supports P2P TXS mode and the specific type it supports.
[0158] Optionally, the format of the second identification information is the same as the second identification information in the TDLS Setup Request frame, and the TDLS Setup Response frame includes a UHR Capabilities element (UHR Capabilities element);
[0159] The second identification information is carried in the P2P TXOP Sharing Mode Support identification field of the UHR capability element.
[0160] The second identification information is included in the UHR capability element.
[0161] For example, the second identification information may be carried in the P2P TXOP Sharing Mode Support identification field, and is used to identify whether the device sending the TDLS Setup Response frame supports the P2P TXS mode and the type of mode it supports.
[0162] In some embodiments, the second identification information includes at least one of the following cases 5 to 8:
[0163] Case five, the second identification information is set to the first parameter value, indicating that the second site device supports the ability to initiate TXS to the TDLS device, and supports the ability to respond to TXS initiated by other TDLS devices; for example, when the second parameter value is set to 3, it indicates that the device sending the TDLS Setup Response frame (the second site device) has the ability to initiate TXS to other TDLS devices, and has the ability to respond to TXS initiated by other TDLS devices.
[0164] Case six, the second identification information is set to the second parameter value, indicating that the second site device supports the ability to initiate TXS to the TDLS device, and does not support the ability to respond to TXS initiated by other TDLS devices; for example, when the second parameter value is set to 2, it indicates that the device (second site device) sending the TDLS Setup Response frame has the ability to initiate TXS to other TDLS devices, but does not have the ability to respond to TXS initiated by other TDLS devices.
[0165] Case seven, the second identification information is set to the third parameter value, indicating that the second site device does not support the ability to initiate TXS to the TDLS device, and supports the ability to respond to TXS initiated by other TDLS devices; for example, when the third parameter value is set to 1, it indicates that the device (second site device) sending the TDLS Setup Response frame does not have the ability to initiate TXS to other TDLS devices, but has the ability to respond to TXS initiated by other TDLS devices.
[0166] Case eight, the second identification information is set to the fourth parameter value, indicating that the second site device does not support the ability to initiate TXS to the TDLS device, and does not support the ability to respond to TXS initiated by other TDLS devices; for example, when the fourth parameter value is set to 0, it indicates that the device (second site device) sending the TDLS Setup Response frame does not have the ability to initiate TXS to other TDLS devices, and does not have the ability to respond to TXS initiated by other TDLS devices.
[0167] Step 204: The first site device receives a TDLS Setup Response frame sent by the second site device.
[0168] After receiving the TDLS Setup Response frame, the first site device determines the second site device's capability to support the P2P TXS mode based on the second identification information. If the first site device and the second site device successfully establish a TDLS link, and the first site device holds the first TXOP and the second site device, acting as the TXOP responder, receives data from the first site device, and the second site device has a temporary / burst low-latency service to transmit, then steps 205 to 207 are performed based on the specific capabilities of the first and second identification information.
[0169] Step 205: Within the first TXOP, the first site device sends data to the second site device; wherein the second identification information indicates that the second site device does not support the ability to respond to TXS initiated by other TDLS devices, or the first identification information indicates that the first site device does not support the ability to initiate TXS to the TDLS device.
[0170] The second identification information indicates that the second site device does not support the ability to respond to TXS initiated by other TDLS devices. For example, the second identification information is set to 0 or 2;
[0171] Or the first identification information indicates that the first site device does not support the capability of initiating TXS to the TDLS device, and the second identification information is set to 1;
[0172] In any of the above situations, within the first TXOP, the first site device sends data to the second site device, and the second site device continues to maintain a receiving state within the first TXOP to receive the data sent by the first site device.
[0173] Step 206: The first site device receives a first TXOP sharing request sent by the second site device; wherein the first TXOP sharing request is used to request the first site device to share part of the transmission time within the first TXOP for the second site device to perform low-latency service transmission; wherein the second identification information identifies that the second site device supports the ability to respond to TXS initiated by other TDLS devices, and the first identification information identifies that the first site device supports the ability to initiate TXS to the TDLS device;
[0174] The second identification information identifies that the second site device supports the ability to respond to TXS initiated by other TDLS devices, and the first identification information identifies that the first site device supports the ability to initiate TXS to the TDLS device. For example, the second identification information is set to 1 (or 3) and the first identification information is set to 2 (or 3). Then, within the first TXOP, when the second site device sends a first TXOP sharing request (such as an ACK or BlockAck frame) to the first site device, it requests the first site device to share part of the first TXOP for low-latency communication service transmission.
[0175] Step 207: Send a second TXOP sharing request to the second site device; wherein the second TXOP sharing request is used to request the second site device to share part of the transmission time within the second TXOP for the first site device to perform low-latency service transmission; wherein the first identification information identifies the ability of the first site device to support responding to TXS initiated by other TDLS devices, and the second identification information identifies the ability of the second site device to support initiating TXS to the TDLS device.
[0176] Among them, the first identification information identifies that the first site device supports the ability to respond to TXS initiated by other TDLS devices, and the second identification information identifies that the second site device supports the ability to initiate TXS to the TDLS device; for example, the first identification information is set to 1 (or 3), and the second identification information is set to 2 (or 3), then in the second TXOP (the second site device is the TXOP holder), when the first site device sends a second TXOP sharing request (such as an ACK or BlockAck frame) to the second site device, it requests the second site device to share part of the second TXOP for low-latency communication service transmission.
[0177] In some embodiments, after step 206, the method further includes:
[0178] Step 208: In response to the first TXOP sharing request, the first site device sends a first multi-user request to send transmission opportunity sharing trigger (Multi User TXOP sharing Trigger, MU-RTS TXS) frame to the second site device; the first MU-RTS TXS Trigger frame includes a User Info field, and the User Info field includes device identification information of the second site device.
[0179] After the first site device receives the first TXOP sharing request sent by the second site device, the first site device sends a MU-RTS TXS Trigger frame to share part of the transmission time of the first TXOP with the second site device. The MU-RTS TXS Trigger frame includes a User Info field, and the User Info field includes an identifier of the target second site device.
[0180] Optionally, when the second site device is not an affiliated STA of a non-AP MLD, the identifier of the second site device may be a media access control layer (MAC) address of the second site device; when the second site device is an affiliated STA of a non-AP MLD, the identifier of the second site device is set to the MAC address of the MLD to which the second site device is affiliated.
[0181] Correspondingly, the User Info field of the first MU-RTS TXS Trigger frame includes the device identification information of the second site device, and transmits the low-latency service within the transmission time indicated by the MU-RTS TXS Trigger frame, that is, the identifier of the User Info field matches the second site device, and the second site device uses the transmission time allocated by the first site device to transmit its cached temporary / burst low-latency communication service;
[0182] or
[0183] The User Info field does not include the device identification information of the second site device. Within the first TXOP, the receiving state is maintained to receive data sent by the first site device. That is, the identifier of the User Info field does not match that of the second site device. The second site device does not respond and maintains the receiving state.
[0184] In some embodiments, after step 207, the method further includes:
[0185] Step 209: In response to the second TXOP sharing request, the second site device sends a second MU-RTS TXS Trigger frame to the first site device; the second MU-RTS TXS Trigger frame includes a User Info field, and the User Info field includes device identification information of the first site device.
[0186] After the second site device receives the second TXOP sharing request sent by the first site device, the second site device sends a MU-RTS TXS Trigger frame to share part of the transmission time of the second TXOP (the TXOP held by the second site device) with the first site device. The MU-RTS TXS Trigger frame includes a User Info field, and the User Info field includes an identifier of the target second site device.
[0187] Optionally, when the first site device is not an affiliated STA of a non-AP MLD, the identifier of the first site device may be the MAC address of the first site device; when the first site device is an affiliated STA of a non-AP MLD, the identifier of the first site device is set to the MAC address of the MLD to which the first site device is affiliated.
[0188] In some embodiments, during the transmission time shared by the first site device to the second site device, the first site device sends data only when receiving a data sending request from the second site device and responding to the data sending request.
[0189] Among them, during the transmission time shared by the first site device to the second site device, the first site device can send data unless the second site device sends data to the first site device and requests a response; in other cases, the first site device does not send data, for example, setting its network allocation vector (NAV) to a busy state.
[0190] As an example, see Figure 3, which illustrates a specific application process of an embodiment of the present disclosure, in which STA1 serves as the first station device and the TXOP holder, and STA2 serves as the second station device. Figure 3 uses step 206 as an example for illustration. Steps 205 and 207 are similar and are not further described here.
[0191] Step 301: STA1 sends a TDLS Setup Request frame to STA2. The TDLS Setup Request frame includes first identification information indicating STA1's support capability for the P2P TXS mode. The first identification information indicates that the first station device supports the capability of initiating TXS to the TDLS device.
[0192] In step 302, STA2 sends a TDLS Setup Response frame to STA1. The TDLS Setup Response frame includes second identification information indicating STA2's ability to support the P2P TXS mode. The second identification information indicates the second station device's ability to respond to TXS initiated by other TDLS devices.
[0193] Step 303: When the first TXOP arrives, STA1, as the TXOP holder, sends an RTS frame to STA2.
[0194] In step 304, STA2, as the TXOP Responder, replies with a CTS frame to STA1.
[0195] Step 305: STA1 and STA2 transmit non-low-latency service data frames (data).
[0196] Step 306: STA2 transmits a low-latency service to other devices.
[0197] For example, the second site device has temporary / burst low-latency communication services to transmit to other communication devices.
[0198] In step 307, STA2 sends a first TXOP sharing request (BA frame in FIG3 ) to STA1, requesting STA1 to share part of the transmission time in the first TXOP for STA2 to perform low-latency service transmission.
[0199] In step 308 , STA1 responds to the first TXOP sharing request, and the first station device sends a first MU-RTS TXS Trigger frame to STA2, sharing the transmission time with STA2 through the first MU-RTS TXS Trigger frame.
[0200] In step 309, STA2 sends an RTS frame to other devices (receiving ends of temporary / burst low-latency communication services, which may be APs or STAs).
[0201] As shown in FIG3 , at step 309 when the first TXOP arrives, the NAV of the other device is set to a busy state; and at step 310 , the other device resets its NAV to access the channel to receive the low-latency communication service.
[0202] In step 311, the other device sends a CTS frame to STA2.
[0203] Step 312: STA2 transmits low-latency service data frames (data) with the other devices.
[0204] Step 313: Other devices reply to STA2 with a BA frame to confirm receipt of the low-latency service data.
[0205] The low-latency service data transmission between STA2 and the other devices is completed. As shown in step 313, the first TXOP may still have TXOP time left, so non-low-latency service data frames can continue to be transmitted between STA1 and STA2. The embodiments of the present disclosure will not be repeated here.
