Subspace relay station, subspace relay booster station, or communications relay was a specific type of communication relay station incorporating a subspace relay. Typically, they were part of a Subspace relay network.

In the Federation, the performance of these stations was tested according to criteria established in STFL spec 0473/111243. If a station was not up to spec, it was repaired on site. A 4.2 gigawatt power generator was enough to sustain such a station. (TNG: "Conspiracy", okudagram; TNG: "Who Watches The Watchers")

In 2364, prior to stardate 41775, the Federation starships USS Aleo and USS White Sands tested the stations on the Rigel/Andor link. (TNG: "Conspiracy", okudagram)

In the Treaty of Armens (2255), one of the provisions read, "Third party assistance may be requested from a Federation Starfleet vessel or a Sheliak Corporate spacecraft if the distance from the vessel to the respective homeworld is greater than five thousand (5.0×10³) light years. UFP Standards Measurement Bureau Units. Assistance may also be requested if the vessel is less than 1,000 light years from a standard UFP subspace relay booster station." (TNG: "The Ensigns of Command", okudagram)

The Cardassian world Loval contained a a small subspace relay station associated with its civilian outpost. (DS9: "Return to Grace")

In 2371, a joint effort between the Federation and Cardassian scientists led to the creation of a relay station being built on the Gamma Quadrant side of the Bajoran wormhole to aid communications. (DS9: "Destiny")

In 2374 Voyager encountered two Hirogen relay stations which they used to communicate with Starfleet Command from the Delta Quadrant. (VOY: "Message in a Bottle", "Hunters")
