Furthermore, those skilled in the art will appreciate that the term "Access Point (AP)" in accordance with the principles and functions described herein may also be used to describe an access port or any other access point capable of receiving and transmitting wireless signals within a network architecture, and thus, the use of an access point is merely exemplary.
Fig. 2 is a flow chart of a time domain cooperative data transceiving method according to an embodiment of the present invention. As shown in fig. 2, the time domain cooperative data transceiving method includes the following:
110. The second access point receives a first notification message from the first access point, wherein the first notification message comprises service period information of a first R-TWT of the first access point and an indication that the first R-TWT is in an activated state. Accordingly, the first access point sends a first notification message to the second access point.
Optionally, the first notification message may include an R-TWT PARAMETERS parameter and an R-TWT scheduling info parameter, where the R-TWT PARAMETERS parameter includes service period information of the first R-TWT, such as start time, transmission duration, etc., and the value of the R-TWT scheduling info parameter may indicate that the first R-TWT is in an active state.
Optionally, before the first access point sends the first notification message to the second access point, when the first access point receives an interference indication message from a first member device of a first R-TWT of the first access point or detects that received interference data is greater than a second threshold, the first access point may determine an interference source, where the interference sources are the second access point, and send the first notification message to the second access point so that the second access point enables the service period offset according to the first notification message, where the first notification message includes service period information of the first R-TWT and an indication that the first R-TWT is in an active state. The interference indication message may include a signal-to-interference ratio, an identification BSSID of an interference source obtained from the interference data, or an address of the second access point. Or the interference indication information of the STA2 is determined by the BSSID, and the first access point can determine the interference source corresponding to the interference data through the position information between the pre-configured APs. The second threshold value can be set in a self-defined mode according to actual application conditions, and can be the same as or different from the first threshold value. For example, as shown in fig. 1, if STA2 is located in the range of the overlapping radio signal areas covered by two access points, STA2 may be severely interfered, and thus may send an interference indication message to the first access point (AP 1).
120. The second access point sends a first broadcast message, wherein the first broadcast message comprises a service period starting offset value of a second R-TWT of the second access point, the service period starting offset value is determined according to service period information of the first R-TWT, and the service periods of the first R-TWT and the second R-TWT are partially or completely overlapped. Accordingly, the second member device receives the first broadcast message from the second access point.
Optionally, parameters Broadcast TWT ID, TWT offset, and Co-BSSID may be included in the first Broadcast message. The Broadcast TWT ID may represent an identifier of an R-TWT that is set by the second access point and that partially or completely overlaps with the first R-TWT traffic period of the first access point, that is, may be set as an identifier of the second TWT. The TWT offset may represent a traffic period start offset value of the second R-TWT, and may be set according to a difference in start time of the traffic period of the first TWT and the traffic period of the second TWT. The Co-BSSID, which represents an identification of the source of interference of the second access point, may be set as the address of the first access point.
130. And the second access point performs data transmission and reception with the second member equipment according to the service period starting offset value. Correspondingly, the second member equipment receives and transmits data with the second access point according to the service period starting offset value, and the second member equipment is a member of the second R-TWT.
Optionally, the second access point may send a data transceiver trigger message to the second member device after waiting for the duration of the service period to start the offset value, and correspondingly, the second member device receives the data transceiver trigger message from the second access point after waiting for the duration of the service period to start the offset value.
The second member device transmits uplink data to the second access point, and accordingly, the second access point receives uplink data from the second member device. Or the second member device sends a data transceiving response message to the second access point, the data transceiving response message indicates the second access point to send downlink data to the second member device, and accordingly, the second access point receives the data transceiving response message from the second member device and sends the downlink data to the second member device, and the second member device receives the downlink data from the second access point.
Optionally, the second access point receives uplink data from the second member device or transmits downlink data to the second member device after waiting for the traffic period to begin for the offset value duration. The second member device transmits uplink data to the second access point or receives downlink data from the second access point after waiting for the traffic period to start the offset value duration.
In some embodiments, the second access point transmits a trigger message to a second member device joining the second R-TWT and, correspondingly, the second member device receives the trigger message from the second access point. Optionally, the second access point updates the transmission duration occupied by the second R-TWT traffic period to the transmission duration of the traffic period of the second R-TWT plus TWT offset. And in the updated service period of the second R-TWT, the AP2 sends a trigger message to the second member equipment.
In some embodiments, the second access point receives a response message from the second member device, the response message including an indication of whether the second member device is enabled for the traffic period offset.
Optionally, a TWT offset enable parameter may be included in the response message, TWT offset enable parameter indicating whether the second member device enables the traffic period offset. The value of TWT offset enable parameter may be set to 0 or 1,1 indicating an active traffic period offset, and 0 indicating an inactive traffic period offset.
Optionally, when the second member device detects that the interference data from the first access point is greater than the first threshold value, a response message is sent to the second access point, and the response message indicates that the second member device enables the service period offset. Accordingly, the response information received by the second access point indicates to the second member device to enable the traffic period offset. The first threshold value can be set in a self-defined mode according to actual application conditions.
Optionally, when the second member device detects that the interference data from the first access point is less than or equal to the first threshold value, a response message is sent to the second access point, and the response message indicates that the second member device does not enable the service period offset. Accordingly, the response information received by the second access point indicates that the second member device does not enable the traffic period offset; the second member device may send uplink data to the second access point or receive downlink data sent by the second access point.
Optionally, when the second member device detects that the interference data from the first access point is less than or equal to the first threshold value, a response message is sent to the second access point, and the response message indicates that the second member device does not enable the service period offset. The second access point receives response information indicating that the second member equipment does not enable the service period offset, the second member equipment can send uplink data to the second access point, the second access point receives the uplink data from the second member equipment, or the second access point sends downlink data to the second member equipment after waiting for the service period beginning offset value duration, and the second member equipment receives the downlink data from the second access point after waiting for the service period beginning offset value duration.
For example, as shown in fig. 1, the second member device STA3 is located within the overlapping area of the wireless signal areas covered by the two access points, and detects that the interference data from the first access point may be greater than the first threshold, so the STA3 may enable the traffic period offset. The STA4 is not located in the range of the overlapping area of the wireless signal areas covered by the two access points, and the detected interference data from the first access point may be less than or equal to the first threshold, so that the STA4 may not enable the service period offset, may directly perform data transceiving according to the service period information of the original second R-TWT, or may perform transceiving according to the service period information of the second R-TWT, and may perform transceiving according to the service period start offset value. Thereby reducing data interference between the two access points and minimizing data delay.
In some embodiments, when all first member devices exit the first R-TWT, or the first member device that sent the interference indication information exits the first R-TWT, a second notification message is sent to the second access point, where the second notification message includes traffic period information of the first R-TWT and an indication that the first R-TWT is in an idle state. Accordingly, the second access point receives a second notification message from the first access point.
The second notification message may include an R-TWT PARAMETERS parameter and an R-TWT scheduling info parameter, where the R-TWT PARAMETERS parameter includes service period information of the first R-TWT, such as start time, transmission duration, etc., and the value of the R-TWT scheduling info parameter may indicate that the first R-TWT is in an idle state.
And the second access point sends a second broadcast message which comprises an indication of the stop service period offset.
Optionally, parameters Broadcast TWT ID and TWT offset may be included in the first Broadcast message. The Broadcast TWT ID may represent an identifier of an R-TWT that is set by the second access point and that partially or completely overlaps with the first R-TWT traffic period of the first access point, that is, may be set as an identifier of the second TWT. TWT offset may represent a traffic segment start offset value of the second R-TWT, may be set to 0, and represents a stop traffic segment offset. Optionally, the parameter Broadcast TWT ID may be included in the first Broadcast message, and TWT offset is not included, i.e. the stop traffic period offset is indicated.
As can be seen from the above, when the wireless signal areas covered by the first access point and the second access point overlap, and the service periods of the first R-TWT of the first access point and the second R-TWT of the second access point overlap partially or completely, the first access point may send a notification message to the second access point to notify that the second access point performs coordinated data transmission and reception in the time domain, for example, the service period of the second R-TWT is offset, and the second access point may negotiate the service period offset with the second member device through a broadcast message, a trigger message, or the like, so that when the second member device starts the service period offset, data transmission and reception are performed according to the service period start offset value.
In order to better implement the method, the application also provides a time domain cooperative data transceiver device.
