Abstract: A method and apparatus for wireless communication may provide for mobility in a Multi-Point HSDPA network capable of downlink aggregation. Some aspects of the disclosure provide modified mobility events utilized for altering the Active Set for a UE. Here, the addition of a cell to the Active Set can coincide with making that cell a secondary serving cell. Further, the deletion of a secondary serving cell from the Active Set can coincide with switching off the Multi-Point HSDPA mode. Still further, a modified mobility event for an HSDPA serving cell change can be utilized to swap a primary serving cell and a secondary serving cell.

Abstract: 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.

Abstract: 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.

Abstract: Systems and methodologies are described that facilitate dynamic load balancing in a communications network. In particular, one or more mobile devices can send random access preambles on an uplink frequency paired to a downlink frequency employed to connect the one or more mobile devices to a base station. The base station can determine if an uplink frequency load imbalance exists based upon the random access preambles. The base station can transmit an indicator on an acquisition indicator channel to at least one mobile device wherein the indicator includes a command to transition to a new uplink frequency. The mobile device can switch uplink frequencies in response to the command.

Abstract: A base station (e.g., a Node B in a Multi-Point HSDPA network) calculates an amount of data to request from a network node (e.g., a radio network controller or RNC). As a part of the algorithm utilized, a length of a queue at the Node B for buffering the flow may be dynamically adjusted in an effort to optimize the trade-off between buffer underrun and skew. Further, a network node (e.g., the RNC) responds to Node B flow control requests. Here, the RNC may determine the amount of data to send to the Node B in response to the flow control message from the Node B, and may send the data to the Node B. In various aspects of the present disclosure involving a Multi-Point HSDPA system, the flow control algorithm at the RNC coordinates packet flow to the primary serving cell and the secondary serving cell for the UE.
