Systems and methods are provided for transmitting a relay search request frame from a source relay edge directional multigigabit (DMG) station STA (REDS) to the AP and receiving a relay search response frame including a list of at least a first and second relay DMG STA (RDS) in a wireless network. Systems and methods are further provided for transmitting over a first data stream through a direct link between the source REDS and the destination REDS, transmitting over a second data stream through the first RDS between the source REDS and the destination REDS, and transmitting over a third data stream through the second RDS between the source REDS and the destination REDS. Directional-band relay in wireless communications may be used in range extension where two wireless nodes may set up a relayed link without first forming a direct link between them.
