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： Techniques for supporting data transmission on multiple carriers in a wireless communication system are described. A user equipment (UE) may determine available transmit power for data transmission on multiple carriers. The UE may distribute the available transmit power to multiple carriers (e.g., using uniform power distribution, greedy filling, water filling, etc.) to obtain allocated transmit power for data for each carrier. The UE may send at least one resource request with information indicative of the allocated transmit power for each of the multiple carriers to a Node B. The UE may receive at least one resource grant with information indicative of granted transmit power for each of at least one carrier, which may be all or a subset of the multiple carriers. The UE may send data on the at least one carrier and may limit its transmit power for each carrier to the granted transmit power for that carrier.

摘要： 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.

摘要： Techniques for scheduling data transmission on multiple carriers in a wireless communication system are described. In one design, a scheduler may receive requested power headrooms for multiple carriers from a user equipment (UE), one requested power headroom for each carrier. Each requested power headroom may be indicative of transmit power usable by the UE for transmission on an associated carrier. The scheduler may also receive queue information indicative of data to transmit by the UE. The scheduler may redistribute the requested power headrooms across the multiple carriers (e.g., based on water filling or greedy filling) to obtain redistributed power headrooms for the multiple carriers. The scheduler may schedule the UE for data transmission on the uplink based on the redistributed power headrooms and the queue information. The scheduler may obtain and send at least one granted power headroom for at least one carrier to the UE.

摘要： Systems and methodologies are described that facilitate split a common total power resource among a plurality of carriers. A power distribution scheme can be employed jointly across the plurality of carriers to determine an amount of power to allocate to respective carriers. Based upon an amount of power allocated, a packet format can be selected for each carrier based upon the amount of power allocated to the carrier and/or a serving grant associated with the carrier.
