A technique of power control in a wireless relay network may include receiving a channel measurement report via a relay station from a mobile station attached to the relay station, and determining a mobile station-specific downlink data transmission power level for the relay station to transmit data to the mobile station based at least in part on the received channel measurement report from the mobile station.

Power control and channel reuse techniques for wireless relay networks

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.

Relay-station assignment/re-assignment and frequency re-use

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.

Apparatus, and an associated method, for a radio communication system having a sending station and a receiving station. The sending station sends data pursuant to a communication service and ultrawide band signals pursuant to a selected time-hopping sequence. An ultrawide band signal detector is positioned at the receiving station. The ultrawide band signal detects the ultrawide band signal transmitted thereto. Correlation is made between the detected ultrawide band signal and a locally-generated replica signal. Correlations therebetween are used to facilitate various receiving station operations, such as equalization operations upon received data, time synchronization of the receiving station to the sending station, and position determination of the positioning of the receiving station.

Apparatus, and an associated method, for allocating channels within a cell of a cellular communication system. Allocations are made by an allocator based upon determinations made by a determiner of the likelihood of movement of the mobile station. Determinations made by the determiner are made responsive to analyses of indicia of prior movement behavior of the mobile station stored at a home location register associated with the mobile station. Channel reuse is effectuated if the mobile station is determined to be stationary or moving at a speed less than a selected threshold. Otherwise, uniquely-assigned channels are allocated to the mobile station.
