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.

Abstract: Methods for use in multi-hop relay networks are described. One method includes receiving a first message from a first relay station requesting a temporary suspension of communication between the first relay station and one or more user equipment. In response to receiving the first message, a second message is transmitted to the one or more user equipment. The second message includes instructions to the user equipment to temporarily suspend communication with the first relay station at a specific time. A third message is transmitted to the first relay station. A scanning operation is performed at the specified time in response to receiving the third message. A second method for use in multi-hop relay networks is also described. The second method includes transmitting a neighbor information message. The neighbor information message includes a relay zone offset indicating the start of a station in a frame structure. Several apparatus are also described.

Abstract: The present invention provides a new and unique method and apparatus for providing an estimate of a mobile location of a wireless node, point or terminal in a wireless local area network (WLAN) or other suitable network, the estimate being based on a correlation of a radio frequency (RF) signal strength measurement and a grid point in a signal strength database or radio map. The signal strength database or radio map is built using a signal strength fingerprint algorithm. The signal strength fingerprint algorithm includes selecting and measuring a set of grid points in the wireless local area network (WLAN) or other suitable network.

Abstract: Positioning beacons (109-a . . . 109-d; 602-1 . . . 602-K) are shown in a target area (100) of a location detection system (600) with location areas (103-a . . . 103-g) in the target area associated with potential beacon positions (102-a . . . 102-g) and represented by vertices (106-a . . . 106-g) of a graph (105). Reliable connectivity between location areas is represented by edges between vertices that represent the location areas. The beacons are assigned to location areas of a subset of vertices of the graph, which subset represents a robust 1-identifying code. The graph may be constrained to a regular topology to exploit availability of optimum or close-to-optimum t-edge-robust and t-vertex-robust 1-identifying codes for such regular topologies. A greedy search algorithm (400-425) may be used to find a small subset of vertices representing t-vertex-robust 1-identifying codes.
