背景技术Background technique

As the use of wireless local area networks (WLANs) continues to grow, it is increasingly important to provide wireless data services in many environments, such as homes, businesses, and hotspots. In particular, video traffic will continue to be the dominant traffic type in many WLAN deployments. The throughput requirements of these applications are evolving due to the advent of 4k and 8k video (20Gbps uncompressed rate). New high-throughput, low-latency applications such as virtual or augmented reality, gaming, remote offices, and cloud computing will proliferate (for example, real-time gaming with sub-5ms latency).

鉴于这些应用程序的高吞吐量和严格的实时延迟要求，用户期望通过WLAN支持其应用程序时，吞吐量更高，可靠性更高，延迟和抖动更少，电源效率更高。用户期望改进与时敏网络(TSN)的集成，以支持异构以太网和无线LAN上的应用程序。802.11be网络旨在通过进一步提高总吞吐量和降低延迟来确保WLAN的竞争力，同时确保与旧版技术标准向后兼容和共存。在2.4GHz，5GHz和6GHz频段运行的802.11兼容设备。Given the high throughput and stringent real-time latency requirements of these applications, users expect higher throughput, higher reliability, less latency and jitter, and better power efficiency when supporting their applications over WLAN. Users expect improved integration with Time Sensitive Networking (TSN) to support applications over heterogeneous Ethernet and wireless LANs. 802.11be networks are designed to ensure WLAN competitiveness by further increasing overall throughput and reducing latency, while ensuring backward compatibility and coexistence with legacy technology standards. 802.11 compatible devices operating in the 2.4GHz, 5GHz and 6GHz bands.

在802.11be网络中，提出了基于AP调度的点对点通信增强方式，由AP统一调度无线资源，在减少中间传输节点和降低传输延迟的同时，保证网络内其他设备的收发不会因为干扰而丢包。In the 802.11be network, a point-to-point communication enhancement method based on AP scheduling is proposed. The AP schedules the wireless resources uniformly. While reducing the intermediate transmission nodes and reducing the transmission delay, it ensures that the transmission and reception of other devices in the network will not be lost due to interference. .

发明内容SUMMARY OF THE INVENTION

Way. Before that, 802.11 network supports direct device connection, which is also a point-to-point transmission method, but in the previous two scenarios, the first is without AP, so that the transmission will not interfere with the transmission of other devices, and the second is with AP , after the two devices establish a connection through the AP, they will transmit directly. In this mode, it will cause interference to the data transmission between other devices within the coverage area of the AP and the AP. Therefore, it is proposed in 802.11be that the AP allocates point-to-point Wireless resources for communication, so as to avoid the impact of point-to-point communication on the performance and throughput of the entire network in scenarios with APs.

时隙(slot)为无线局域网中最小时间单位，例如，设置一个slot是9微秒，那么传输时间为5个slot，即为45微秒。A time slot (slot) is the smallest time unit in a wireless local area network. For example, if a slot is set to 9 microseconds, the transmission time is 5 slots, which is 45 microseconds.

AP设置P2P parameter set的方式可以是根据预先评估的业务数据模型分配，例如，以视频传输业务模型作为P2P业务模型的标准，The way the AP sets the P2P parameter set can be allocated according to the pre-evaluated service data model. For example, the video transmission service model is used as the standard of the P2P service model.

帧率：60Hz；Frame rate: 60Hz;

分辨率：3840x2160；Resolution: 3840x2160;

像素大小：24bits/pixel；Pixel size: 24bits/pixel;

压缩率：100；Compression ratio: 100;

那么每16.7ms发送一帧视频数据，那么传输速率大概为120Mbps。Then one frame of video data is sent every 16.7ms, so the transmission rate is about 120Mbps.

然后根据MCS对应速率表，如表1，计算传输时间，然后根据每个slot的时间值，确定可以传输完一帧数据所需要的slot的数量。Then, according to the MCS corresponding rate table, such as Table 1, calculate the transmission time, and then determine the number of slots required to transmit a frame of data according to the time value of each slot.

3.STA1有数据需要发送到STA2(即，STA1为发起终端，STA2为对等终端)，则STA1发送承载数据的消息给AP，需要说明的是，术语“承载数据的消息”中的“数据”既可以指业务数据，也可以指服务请求指示。示例地，承载数据的消息中包含以下参数：3. STA1 has data that needs to be sent to STA2 (that is, STA1 is the initiating terminal and STA2 is the peer terminal), then STA1 sends a data-carrying message to the AP. It should be noted that the term "data-carrying message" in "data" ” can refer to both business data and service request indications. Illustratively, the data-carrying message contains the following parameters:

SA：源地址，这里设置为STA1的地址；SA: source address, here is set to the address of STA1;

DA：目标地址，这里设置为STA2的地址；DA: target address, here is set to the address of STA2;

6.STA1接收到AP发送的P2P setup消息后，测量STA2的信号，获取STA2的信号强度(RSSI)P1或信号质量Q，其中，Q＝P1/(P1+N)，N为干扰信号的强度，在一些实施例中，如果P2P setup消息中包含参数P2P option，当P2P option的值为“setup”时，STA1获取STA2的信号强度或信号质量。STA1将获取的STA2的信号强度或信号质量与预设的门限值Th-RSSI进行比较，如果STA2的信号强度或信号质量大于或等于Th-RSSI，则根据P2P setup消息中P2P parameter set中给出的P2P操作的资源将数据直接发送到STA2，示例地，具体发送方式包括：6. After STA1 receives the P2P setup message sent by the AP, it measures the signal of STA2 and obtains the signal strength (RSSI) P1 or signal quality Q of STA2, where Q=P1/(P1+N), N is the strength of the interference signal , in some embodiments, if the parameter P2P option is included in the P2P setup message, when the value of the P2P option is "setup", STA1 obtains the signal strength or signal quality of STA2. STA1 compares the acquired signal strength or signal quality of STA2 with the preset threshold Th-RSSI, and if the signal strength or signal quality of STA2 is greater than or equal to Th-RSSI, according to the given value in the P2P parameter set in the P2P setup message. The resource of the P2P operation is sent directly to the STA2. For example, the specific sending method includes:

6.1如果P2P parameter set包含MCS，P2P bitmap和P2P interval，则根据参数中的MCS对数据包进行调制编码，在P2P bitmap中指定的时段发送数据，并按照P2P interval的周期进行周期性数据发送。6.1 If the P2P parameter set contains MCS, P2P bitmap and P2P interval, the data packet is modulated and encoded according to the MCS in the parameter, and the data is sent in the period specified in the P2P bitmap, and periodic data transmission is carried out according to the period of the P2P interval.

示例地，MCS为0，P2P interval为10，P2P bitmap为{1,1,1,0,0,0,0,0,0,0}，其中，1表示P2P时隙，0表示普通时隙，如图3中的P2P slot和Normal slot。本实施例slot包括0和1，也可以采用00和01等，还可以采用字母等其他形式，本申请对此不做限制。如图3所示，在每一个时隙分配周期的前3个时隙，执行P2P操作，STA1将数据直接发送到STA2，AP覆盖范围内的其他终端不可以进行数据传输，在每一个时隙分配周期的后7个时隙，AP覆盖范围内的所有终端均可以进行数据传输，如此以10个时隙为周期进行周期性数据传输。For example, MCS is 0, P2P interval is 10, P2P bitmap is {1, 1, 1, 0, 0, 0, 0, 0, 0, 0}, where 1 means P2P time slot, 0 means normal time slot , such as P2P slot and Normal slot in Figure 3. The slot in this embodiment includes 0 and 1, and may also use 00 and 01, and may also use other forms such as letters, which are not limited in this application. As shown in Figure 3, in the first 3 time slots of each time slot allocation period, the P2P operation is performed, STA1 sends data directly to STA2, and other terminals within the coverage area of the AP cannot perform data transmission. In the last 7 time slots of the allocation period, all terminals within the coverage area of the AP can perform data transmission, so periodic data transmission is carried out with 10 time slots as a period.

6.2如果P2P parameter set包含Link，P2P bitmap和P2P interval，则根据参数中的Link在指定的链路上按照P2P bitmap中指定的时段发送数据，并按照P2P interval的周期进行周期性数据发送。与6.1相同，在一个P2P interval的周期内，在P2P bitmap中指定的P2P时隙，执行P2P操作，STA1将数据直接发送到STA2，AP覆盖范围内的其他终端不可以进行数据传输，在P2P bitmap中指定的普通时隙，AP覆盖范围内的所有终端均可以进行数据传输，如此以P2P interval的周期进行周期性数据传输。6.2 If the P2P parameter set contains Link, P2P bitmap and P2P interval, then according to the Link in the parameter, data is sent on the specified link according to the period specified in the P2P bitmap, and periodic data transmission is carried out according to the period of the P2P interval. Same as 6.1, in a P2P interval period, the P2P operation is performed in the P2P time slot specified in the P2P bitmap, STA1 sends data directly to STA2, and other terminals within the AP coverage area cannot perform data transmission. All terminals within the coverage area of the AP can transmit data in the ordinary time slot specified in

6.3如果P2P parameter set包含P2P duration，则在P2P duration指示的时长内发送数据。示例地，P2P duration为20，则在P2P duration指示的20个slot内，执行P2P操作，STA1将数据直接发送到STA2，AP覆盖范围内的其他终端不可以进行数据传输，在其余slot，AP覆盖范围内的所有终端均可以进行数据传输。6.3 If the P2P parameter set contains the P2P duration, the data is sent within the duration indicated by the P2P duration. For example, if the P2P duration is 20, the P2P operation is performed within the 20 slots indicated by the P2P duration, and STA1 sends data directly to STA2, and other terminals within the coverage area of the AP cannot transmit data. In the remaining slots, the AP covers All terminals within range can transmit data.

6.4如果P2P parameter set包含P2P duration和Channel，则在P2P duration指示的时长内，在Channel指示的信道所在频段上发送数据。示例地，P2P duration为20，Channel指示的P2P操作使用的频段为2，则在P2P duration指示的20个slot内，在频段2上执行P2P操作，STA1将数据直接发送到STA2，AP覆盖范围内的其他终端不可以进行数据传输，而其他带宽仍可以提供给其他终端使用，在其余slot，AP覆盖范围内的所有终端均可以进行数据传输。6.4 If the P2P parameter set includes P2P duration and Channel, then within the time period indicated by the P2P duration, data is sent on the frequency band where the channel indicated by Channel is located. For example, if the P2P duration is 20, and the frequency band used for the P2P operation indicated by Channel is 2, then within the 20 slots indicated by the P2P duration, the P2P operation is performed on frequency band 2, and STA1 sends data directly to STA2, within the coverage of the AP. Other terminals in the AP cannot transmit data, and other bandwidths can still be provided to other terminals. In the remaining slots, all terminals within the coverage area of the AP can transmit data.

6.5如果P2P parameter set包含P2P duration和P2P interval，则在P2P duration指示的时长内发送数据，并按照P2P interval指示的周期进行周期性数据发送。通常情况下，P2P duration小于P2P interval。示例地，P2P duration为5，P2P interval为10，则在P2P duration指示的5个slot内，执行P2P操作，STA1将数据直接发送到STA2，AP覆盖范围内的其他终端不可以进行数据传输，在其余slot，AP覆盖范围内的所有终端均可以进行数据传输，如此以10个时隙为周期进行周期性数据传输。6.5 If the P2P parameter set includes P2P duration and P2P interval, the data is sent within the time period indicated by the P2P duration, and periodic data transmission is performed according to the period indicated by the P2P interval. Typically, the P2P duration is less than the P2P interval. For example, if the P2P duration is 5 and the P2P interval is 10, the P2P operation is performed within the 5 slots indicated by the P2P duration, STA1 sends data directly to STA2, and other terminals within the coverage of the AP cannot transmit data. For the remaining slots, all terminals within the coverage area of the AP can perform data transmission, so periodic data transmission is performed with 10 time slots as a period.

7.STA1将获取的STA2的信号强度或信号质量与预设的门限值Th-RSSI进行比较，如果STA2的信号强度或信号质量小于Th-RSSI，则将需要发送给STA2的数据发送给AP。7. STA1 compares the acquired signal strength or signal quality of STA2 with the preset threshold Th-RSSI. If the signal strength or signal quality of STA2 is less than Th-RSSI, it will send the data that needs to be sent to STA2 to the AP .

Payload：从STA1发送到STA2的数据。Payload: Data sent from STA1 to STA2.

5.AP查看STA1和STA2是否都支持P2P操作，如果都支持，则发送触发消息给STA1，示例地，消息中包含以下参数：5. The AP checks whether both STA1 and STA2 support the P2P operation, and if both support it, it sends a trigger message to STA1. For example, the message contains the following parameters:

Target：用于指示要测量的目标，这里设置为STA2的标识或地址。Target: used to indicate the target to be measured, which is set to the identity or address of STA2 here.

在一些实施例中，触发消息中还包含参数Measure enable：用于表示是否指示终端执行测量，示例地，设置为1表示指示终端执行测量。In some embodiments, the trigger message also includes a parameter Measure enable: used to indicate whether to instruct the terminal to perform measurement, for example, setting it to 1 indicates that the terminal is instructed to perform measurement.

6.STA1接收到AP的触发消息后，执行对STA2的测量，获取STA2的信号强度或信号质量，将包含获取的STA2的信号强度或信号质量的消息发送给AP。6. After receiving the trigger message from the AP, STA1 performs measurement on STA2, obtains the signal strength or signal quality of STA2, and sends a message including the obtained signal strength or signal quality of STA2 to the AP.

7.AP接收到测量结果后，比较上报的STA2的信号强度或信号质量与预设的门限值Th-RSSI，如果STA2的信号强度或信号质量大于或等于Th-RSSI，则发送P2P setup消息给STA1，示例地，P2P setup消息中包含以下参数：7. After the AP receives the measurement result, it compares the reported signal strength or signal quality of STA2 with the preset threshold Th-RSSI. If the signal strength or signal quality of STA2 is greater than or equal to Th-RSSI, it sends a P2P setup message For STA1, for example, the P2P setup message contains the following parameters:

P2P parameter set：该参数用于表示分配给P2P操作的资源。其设置方式可参考图2所示实施例中的步骤5，这里不再赘述。P2P parameter set: This parameter is used to indicate the resources allocated to P2P operations. For the setting method, reference may be made to step 5 in the embodiment shown in FIG. 2 , which will not be repeated here.

8.STA1接收到AP发送的P2P setup消息后，根据P2P setup消息中P2P parameter set中给出的P2P操作的资源将数据直接发送到STA2，在一些实施例中，如果P2P setup消息中包含参数P2P option，当P2P option的值为“setup”时，STA1根据P2P setup消息中P2P parameter set中给出的P2P操作的资源将数据直接发送到STA2。其具体的发送方式可参考图2所示实施例中的步骤6，这里不再赘述。8. After STA1 receives the P2P setup message sent by the AP, it directly sends the data to STA2 according to the resources of the P2P operation given in the P2P parameter set in the P2P setup message. In some embodiments, if the P2P setup message contains the parameter P2P option, when the value of the P2P option is "setup", STA1 directly sends data to STA2 according to the resources of the P2P operation given in the P2P parameter set in the P2P setup message. For the specific sending manner, reference may be made to step 6 in the embodiment shown in FIG. 2 , which will not be repeated here.

在一些实施例中，建立点对点通信连接的方法还包括以下步骤：In some embodiments, the method of establishing a point-to-point communication connection further comprises the steps of:

9.如果参数P2P parameter set中包含P2P interval，则STA1以P2P interval为周期测量STA2的信号强度或信号质量，并在非P2P操作时段发送给AP。9. If the parameter P2P parameter set includes P2P interval, STA1 measures the signal strength or signal quality of STA2 with the P2P interval as the period, and sends it to the AP during the non-P2P operation period.

10.AP将每一次STA1发送的STA2的信号强度或信号质量与Th-RSSI进行比较，如果STA2的信号强度或信号质量大于或等于Th-RSSI，则不做操作，如果STA2的信号强度或信号质量小于Th-RSSI，则发送P2P setup消息给STA1，消息中将P2P option设置为“release”，表示释放P2P连接。10. The AP compares the signal strength or signal quality of STA2 sent by STA1 with Th-RSSI each time. If the signal strength or signal quality of STA2 is greater than or equal to Th-RSSI, no operation is performed. If the quality is less than Th-RSSI, send a P2P setup message to STA1, and set the P2P option to "release" in the message, indicating that the P2P connection is released.

11.STA1接收到AP发送的P2P setup消息后，如果P2P option值为“release”，STA1结束使用P2P操作，即将需要发送给STA2的数据发送给AP。11. After STA1 receives the P2P setup message sent by the AP, if the value of the P2P option is "release", STA1 ends the P2P operation and sends the data to be sent to STA2 to the AP.
