1. An apparatus, comprising: at least one processor; and at least one memory storing instructions,
that when executed by the at least one processor cause the apparatus:
on a station utilizing at least an unlicensed first wireless interface transmitting in uplink to a serving access point of a same basic service set in a wireless network, at least to:
with a second wireless interface being different from the unlicensed first wireless interface;
identify that a first channel utilized by the unlicensed first wireless interface is unavailable for the station;
when identifying that the first channel utilized by the unlicensed first wireless interface is unavailable for the station, determine that transmission of a message be in a secondary wireless interface of the station if said station attempts to transmit reliable and low latency type traffic; generate a message to be sent to the serving access point; and
transmit the message to the serving access point;
determine whether to include data payload in the message; and
obtain channel occupancy information based on a capability of the station for sensing multiple channel.
