Target transmission time based transmit scheduling
Methods for scheduling data packets based on a target transmission time may include receiving, from an application layer at a first time, a data packet and an associated latency requirement. The first layer may determine based, at least in part, on the associated latency requirement, a target transmission time. The target transmission time may be a sum of a queuing delay, an expected transmit completion time, and the first time. The data packet may be queued (or scheduled for transmission) based, at least in part, on the target transmission time and an access category assigned to the data packet. The data packet may be transmitted (or scheduled for transmission) from the queue according to the target transmission time. The expected transmit completion time may be a sum of an average contention time for the access category assigned to the data packet and estimated airtime.
