    Abstract: A method and system for improving the reception of uplink transmissions in a heterogeneous wireless communication system includes a high-power node such as a macro-cell and a low-power node such as a femto-cell or pico-cell. To address an uplink imbalance where a nearby low-power node power controls a UE such that uplink transmissions of an HSDPA control channel are poorly received at the serving cell, an RNC can instruct the UE to boost its uplink transmit power, remove the UE from soft handover, or disable power control of the UE by the low-power node. To address inter-cell interference, the RNC can limit the UE transmit power and/or enable the victim cell to suppress the interference. Further, a common control channel can be used to power control UEs outside of the convention set of UEs available for power control.

    Abstract: 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.

    Abstract: A method of wireless communication includes utilizing a first outer loop for single-stream transmissions when a requested PCI by a UE is within a first set. The utilizing the first outer loop includes utilizing a first outer loop margin to adjust a size of a transport block by a first backoff margin when the UE requests a PCI within the first set. The method further includes utilizing a second outer loop for single-stream transmissions when the requested PCI by the UE is within a second set different from the first set. The utilizing the second outer loop includes utilizing a second outer loop margin to adjust the size of the transport block by a second backoff margin when the UE requests a PCI within the second set.
