Thsi answer is WRONG. Sorry about this. Please neglect it.
No, unfortunately you cannot. Your model only has one wireless interface, while a repeater needs two. A single card repeater will wnd up talking to clients half of the time, and to its base station the other half of the time, thus cutting bandwidth in half.
In fact, its User's Guide makes no mention of alternative modes like wireless repeater, range extender, wireless bridge, which are all roughly synonims.
The term WDS does indicate its ability to partake in a Wireless Distribution System, however I believe it is meant to indicate that it can act as a base station, not a
relay-station as required by the OP. Besides, in the manual mentioned above, there is no discussion of WDSes.
