Access Point TXOP Scheduling for Low-Latency Station Uplink

The access point device predicts which station devices will need to transmit latency-sensitive data before the TXOP occurs, and sends a first frame to these predicted station devices in advance to request their buffer status information. This preliminary action allows the access point to prepare resource allocation for uplink latency-sensitive data transmission while the downlink data is being transmitted, ensuring that when the station devices need to transmit, the resources are already allocated and transmission can occur immediately without waiting for traditional buffer status report exchanges.

Instead of requesting buffer status information from all station devices uniformly, the access point device applies local quality by predicting which specific station devices are likely to have latency-sensitive data and only sending the first frame to those predicted station devices. This targeted approach ensures that buffer status information is collected from the relevant stations that need it, maintaining transmission reliability for latency-sensitive data while avoiding unnecessary communication overhead with station devices that do not have such data to transmit.

The access point device performs preliminary prediction of which station devices will need to transmit latency-sensitive data and sends the first frame in advance. Based on the received buffer status information from predicted station devices, the access point device then dynamically allocates resource units for uplink transmission. This preliminary prediction approach simplifies the dynamic allocation process by reducing the number of station devices that need to be considered, making the resource allocation more manageable while still maintaining high adaptability to actual transmission needs.
