    摘要: Embodiments of the claimed subject matter provide a method and apparatus coordinating downlink multipoint transmissions. One embodiment of the method includes transmitting, from a first base station, first information indicating a first constraint on a starting position for downlink data transmission by the first base station or one or more second base stations. This embodiment of the method also includes transmitting, from the first base station, second information that includes a bit. A combination of the bit and the first information indicates the starting position for the downlink data transmission.

    摘要: One embodiment of the method includes defining, at the user equipment, a range for the maximum output power. The range includes a maximum value and a minimum value. The minimum value is based on a maximum power signalled by a base station, a power class of the user equipment, a maximum power reduction permitted, an additional maximum power reduction permitted, a reduction term dependent on transmission bandwidth, and a power management term. The method further includes setting, at the user equipment, the maximum output power within the defined range.

    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 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: In a method of controlling downlink transmission timing at a radio network controller (RNC) in a communication system, a relative window is determined. The relative window represents a time difference between an arrival time of a data frame at the RNC from a core network, and a target transmission time for transmitting the data frame from the RNC to a Node-B. Boundary thresholds that adjoin the relative window are set, and a target arrival time that a data frame is to be received at the RNC is compared to the thresholds. The RNC may send a request to advance or retard sending of the data frame to the core network, depending on whether target arrival time of the data frame is outside one of the thresholds. A data frame received within the relative window is transmitted from the RNC to a Node-B.

    摘要: In the method for enhanced uplink data transmission, a transport channel for each transmission mode is independently generated. Each transport channel has an associated transmission time interval (TTI), and the generated transport channels are multiplexed on a selected TTI basis to form a composite transport channel. The selected TTI is selected from one of the TTIs associated with the independently generated transport channels. The composite transport channel is then mapped onto a physical channel.
