摘要： An exemplary method of communicating includes a relay node that uses a cell identifier that is also used by a base station having a coverage area within which the relay node is located. The method includes determining that a mobile station is within a communication range of the relay node. A transmission power from the relay node is controlled so that the total transmission power of at least one transmission from the relay node and the base station corresponds to a selected transmit power limit. A timing of a downlink transmission from the base station and the relay node is coordinated based on a schedule determined by the base station. At least one uplink control parameter is set at the base station based upon uplink information regarding a link between the mobile station and the relay node.

摘要： A method of configuring user equipment in a wireless communication network to operate to receive a dynamically changing coordinated multipoint transmission from one or more transmission point in said network, a computer program product and network control node operable to perform that method. The method comprises: determining, for the user equipment, a set of two or more transmission points from which the user equipment may receive a transmission and allocating them to a coordinated multipoint transmission measurement set associated with the user equipment; allocating a set of modes of operation of the transmission points in the coordinated multipoint transmission measurement set for communication with the user equipment; associating a codepoint to each mode in the allocated set of modes of operation of the set of transmission points to form a codebook; and informing the user equipment of the codebook. Aspects and embodiments described recognise that without significantly increasing the number of bits required in a downlink control information message, dynamic switching among some preselected or preconfigured coordinated multipoint transmission schemes can be efficiently supported within a network. The configuration of code points interpreted by user equipment may be set on a user equipment by user equipment basis and can be preconfigured by RRC signalling semi-statically.

摘要： A method may include determining a metric for at least one physical resource block of a wireless cellular network in at least a one cell. Each physical resource block may include a set of frequencies, and/or the metric may be based on interference on the at least one physical resource block in the at least one cell. A determination of whether the metric violates a metric threshold may be made, and an overload indicator may be sent to at least one other cell if the metric violates the metric threshold.

摘要： A method is provided for operating a multi-bandwidth OFDMA system that can achieve an enhanced bandwidth efficiency due to windowing without significantly impacting the underlying physical design of the receive filters. The method comprises establishing a bandwidth over which the radio resources transmit signals, the bandwidth being comprised of an edge-band and a center-band. Narrow band radio resources are assigned to a portion of the bandwidth that is at least partially within the edge-band.

摘要： An exemplary method of communicating includes using coordinated scheduling of downlink transmissions in a plurality of cells. The coordinated scheduling includes a serving node in one of the cells currently serving a mobile station pausing downlink transmission on at least one selected resource when a non-serving node in a neighboring one of the cells not currently serving the mobile station transmits a downlink communication intended for the mobile station on the selected resource.
