METHOD AND APPARATUS FOR IMPROVING RELIABLE AND LOW-LATENCY COMMUNICATION UPLINK TRANSMISSION IN THE UNLICENSED SPECTCTRUM

摘要

A system in wireless network comprising at least a Basic Service Set comprising: at least an Access Point utilizing at least an unlicensed first wireless interface; at least one Station utilizing at least a first unlicensed wireless interface, transmitting in uplink to the AP; Said at least one STA further comprises a secondary wireless interface being different from the first unlicensed wireless interface, said STA is configured to, when identifying an unavailability of a first channel utilized in the unlicensed first wireless interface, determine that transmission of a message be in a secondary wireless interface of the STA when it is utilized for Reliable and Low Latency Communication RLLC data transmission, generate a message and then transmit the message to a serving AP. Said AP is configured to, when receiving the message from the STA, determine whether information will be generated based on the message received from the STA, generate at least scheduling information if it is determined that information will be generated and transmit the generated information to the STA.
