Relay operation and roaming operation

A wireless communication device for facilitating wireless communication, comprising processing circuitry configured to cause:

• receiving, from an associated access point having a first data unit to be addressed to the wireless communication device, a measurement announcement frame addressed to one or more neighboring access points and a station, wherein the measurement announcement frame triggers the one or more neighboring access points to transmit a training frame to the station and triggers the station to measure channel information based on training frames from the one or more neighboring access points;
• transmitting a measurement report frame to the associated access point, the measurement report frame including the channel information;
• and
• receiving a second data unit from a relay access point determined based on the measurement report frame, the second data unit being generated by the relay access point based on the first data unit.
