Abstract
This disclosure describes systems, methods, and devices related to enhanced retry count for an uplink (UL) multi-user (MU) transmission. A device may identify a trigger frame received from a first device on a wireless communication channel. The device may determine a quality of service counter associated with an access category. The device may cause to send a frame to the first device based at least in part on the trigger frame. The device may determine an error condition associated with the frame. The device may refrain from incrementing the quality of service counter based on the error condition.
Claims20
A station device (STA) for performing retransmission procedures, the STA comprising processing circuitry and storage, the processing circuitry coupled to the storage, the processing circuitry configured to:
- identify a high efficiency (HE) trigger frame received from an access point device, the HE trigger frame associated with causing transmissions from multiple station devices in a multi-user environment, the multiple station devices comprising the STA;
- cause to send, based on the HE trigger frame, a physical layer (PHY) protocol data unit (PPDU) to the access point device, wherein a retry counter of the STA is set to a value;
- determine an absence of a response to the PPDU in the multi-user environment after a time has elapsed, the absence indicating that no acknowledgement has been received from the access point device in response to the PPDU;
- determine that the PPDU is associated with the HE trigger frame;
- and
- refrain from modifying the value of the retry counter based on the absence and based on the PPDU being associated with the HE trigger frame.
A non-transitory computer-readable medium storing computer-executable instructions which when executed by one or more processors result in performing operations comprising:
- identifying, by a station device (STA), a high efficiency (HE) trigger frame received from an access point device, the HE trigger frame associated with causing transmissions from multiple station devices in a multi-user environment, the multiple station devices comprising the STA;
- causing to send, based on the HE trigger frame, a physical layer (PHY) protocol data unit (PPDU) to the access point device, wherein a retry counter of the STA is set to a value;
- determining an absence of a response to the PPDU in the multi-user environment after a time has elapsed, the absence indicating that no acknowledgement has been received from the access point device in response to the PPDU;
- determine that the PPDU is associated with the HE trigger frame;
- and
- refraining from modifying the value of the retry counter based on the absence and based on the PPDU being associated with the HE trigger frame.
A method comprising:
- identifying, by processing circuitry of a station device (STA), a high efficiency (HE) trigger frame received from an access point device, the HE trigger frame associated with causing transmissions from multiple station devices in a multi-user environment, the multiple station devices comprising the STA;
- causing to send, by the processing circuitry and based on the HE trigger frame, a physical layer (PHY) protocol data unit (PPDU) to the access point device, wherein a retry counter of the STA is set to a value;
- determining, by the processing circuitry, an absence of a response to the PPDU in the multi-user environment after a time has elapsed, the absence indicating that no acknowledgement has been received from the access point device in response to the PPDU;
- determine that the PPDU is associated with the HE trigger frame;
- and
- refraining, by the processing circuitry, from modifying the value of the retry counter based on the absence and based on the PPDU being associated with the HE trigger frame.
