摘要： Systems and methodologies are described that facilitate power distribution and data allocation in a multi-carrier wireless communication system. A portion of transmit power can be pre-allocated to an anchor carrier to support non-scheduled data flows. Remaining power is split among all carriers, including the anchor carrier, after pre-allocation. Data from one or more flows, scheduled and non-scheduled, are allocated to the carriers in accordance with priorities associated with the one or more flows. Allocation of data can be performed sequentially starting with a non-anchor carrier. In addition, non-scheduled data flows can be restricted to the anchor carrier.

摘要： A wireless communication system transmits in a High Speed Downlink Packet Access (HSDPA) by having a Radio Network Controller (RNC) assign portions of data to a first serving cell and a second serving cell for transmitting to a user equipment. The first serving cell transmits data on a first downlink carrier to the user equipment. The second serving cell, which is independent from the first serving cell, transmits data on a second downlink carrier to the user equipment. In an optional aspect, the RNC receives a measurement report from the user equipment on a first uplink carrier via at least one of the first serving cell and the second serving cell.

摘要： A method, apparatus, processing system, and computer program product enable association of mis-aligned subframes from a first and second downlink with one another, such that a HARQ acknowledgment message including jointly encoded feedback for the respective subframes can be correctly interpreted by the corresponding cells. Here, an RNC may provide an RRC message to the UE to associate particular subframes with one another. Further, the RNC may provide NBAP messages to the cells transmitting the downlink signals, so that the cells can associate the HARQ acknowledgment message with the appropriate subframe. Still further, additional signaling provides for changing the set of associated subframes when needed due to a drift in the timing offset between cells.

摘要： Techniques for scheduling users for transmission on the uplink in a wireless communication system are described. A cell may perform interference cancellation for uplink transmissions and may observe lower effective noise and interference due to interference cancellation. The lower effective noise and interference may allow the cell to operate with a higher effective target load, which may support a higher overall throughput for the cell. In one design, an effective target load for a cell using interference cancellation may be determined, e.g., based on a target rise-over-thermal (RoT) for the cell and an interference cancellation efficiency factor. An available load for the cell may be determined based on the effective target load, which may be higher than a target load for the cell without interference cancellation. Users in the cell may then be scheduled for transmission on the uplink based on the available load.

摘要： A wireless communication device includes: an antenna for receiving inbound signals on dual receive channels and transmitting outbound signals on dual transmit channels; a transceiver coupled to the antenna to receive the inbound signals from the antenna and convey the outbound signals; a power controller coupled to the transceiver to control power levels of the outbound signals so a maximum nominal power level of the outbound signals is a first power level; and a processor coupled to the transceiver and the antenna to cause the power controller to control the power levels of the outbound signals so if a power level of a received one of the inbound signals is below a threshold value, then the maximum nominal power level of the outbound signals is a second power level lower than the first power level, wherein the second power level is lower than the first power level.
