Abstract
A prospective relay station sends a report indicative of radio resource sets/preamble sequences used by its neighbors. Where the reported radio resource sets comprise less than all available radio resource sets, a radio resource set that is not indicated in the report is assigned; else where the reported radio resource sets comprise all available radio resource sets, a resource set indicated in the report is assigned. A message is sent to the prospective relay station indicates the assigned radio resource set and an identifier for use as an enabled relay station. The message may include signal strength and IDs. Apparatus, methods and computer programs are detailed for both a base station and the relay node. Radio resource set re-assignment, managed mode relay operations (where the base station schedules traffic among relays using the same radio resource set), and power control of relays and associated mobile stations are also described.
