Abstract
In some examples, an access point (AP) includes a wireless interface, and at least one processor configured to send, to the first wireless device through the wireless interface, a preemption indication to cause the first wireless device to pause data transmission over a wireless channel, and send, to the first wireless device, a resume indication to cause the first wireless device to resume the data transmission over the wireless channel.
Claims9
An access point (AP) comprising:
- a wireless interface;
- and
- at least one processor configured to:
- send, to a first wireless device through the wireless interface, a preemption indication to cause the first wireless device to pause data transmission over a wireless channel, wherein the pausing of the data transmission in response to the preemption indication preempts transmission of a remaining part of a data frame after a first part of the data frame has been transmitted in the data transmission;
- determine that a transmission of the data frame is incomplete and that the remaining part of the data frame was preempted in response to receiving, from the first wireless device, preemption information indicating that transmission of the data frame by the first wireless device is incomplete;
- after sending the preemption indication and in response to receipt of the preemption information, send, to one or more other wireless devices, a trigger indication to trigger the one or more other wireless devices to send data in a pre-allocated resource, and
- send, to the first wireless device, a resume indication to cause the first wireless device to resume a transmission over the wireless channel, wherein the resume indication is to cause the first wireless device to continue sending the remaining part of the data frame that was preempted, and wherein the remaining part of the data frame comprises a Medium Access Control (MAC) header that has a same sequence number and destination MAC address as a sequence number and destination MAC address in the data frame.

A method performed by an access point (AP), the method comprising:
- sending, to a wireless device, a preemption indication to cause the wireless device to pause data transmission over a wireless channel, wherein the pausing of the data transmission in response to the preemption indication preempts transmission of a remaining part of a data frame after a first part of the data frame has been transmitted in the data transmission;
- determining that a transmission of the data frame is incomplete and that the remaining part of the data frame was preempted in response to receiving, from the wireless device, preemption information indicating that transmission of the data frame by the wireless device is incomplete;
- after sending the preemption indication and in response to receipt of the preemption information, sending, to one or more other wireless devices, a trigger indication to trigger the one or more other wireless devices to send data in a pre-allocated resource;
- and
- sending, to the wireless device, a resume indication to cause the wireless device to resume a transmission over the wireless channel, wherein the resume indication is to cause the wireless device to continue sending the remaining part of the data frame that was preempted, and wherein the remaining part of the data frame comprises a Medium Access Control (MAC) header that has a same sequence number and destination MAC address as a sequence number and destination MAC address in the data frame.
