Abstract: In aspects, a user equipment (UE) forms groups of overlapping uplink transmissions among component carriers (CCs), and moves in time all uplink transmissions within a group, except an earliest transmission, to align leading edges. The UE then determines, for each uplink transmission, if a joint timeline is satisfied, and allocates total transmission power depending on whether the timeline is satisfied for all uplink transmissions. In aspects, a base station transmits, to a UE, a transmit power configuration that identifies a reserved power for uplink transmissions of cell groups. The base station then transmits, to the UE, an uplink grant or configuration that identifies a transmission power for a cell group in excess of its reserved power, and receives, from the UE, uplink transmissions that exhibit an allocation of total transmission power according to the reserved power and the transmission power for the cell group in excess of the reserved power.

Abstract: Provided are a system, method and computer program product for redistribution of data in an online shared nothing database, said shared nothing database comprising a plurality of original partitions and at least one new partition.

Abstract: Techniques are disclosed for implementing a unified partitioning scheme within distributed database systems to allow a table to be horizontally partitioned and those partitions stored on and serviced by a storage group. A storage group is a subset of storage manager (SM) nodes, and each SM node is configured to persist database data in durable storage. The distributed database system assigns each storage group to a subset of SM nodes. The distributed database system can address each storage group using a symbolic mapping that allows transactions to identify a particular storage group, and to direct read and write operations to a subset of SM nodes servicing that storage group. An administrator can update this mapping on-the-fly to cause the distributed database system to dynamically adjust an implemented partitioning scheme without necessarily interrupting on-going database operations.

Abstract: A framework for memory optimization of database indexes, and in particular for aging full-text index data, is described herein. In one embodiment, if, while a database table is aged, there are index tables associated with the database table, the associated index tables are automatically aged. This way, the system memory footprint will be reduced, leading to reduced cost as less system memory is required to perform remaining operations, and leading to increased performance as more system memory is available for other operations.

Abstract: A method for equalizing a wireless communication channel includes transmitting a data signal over a primary channel. During transmission of the data signal, a corresponding data signal is sent over a secondary channel.

These differences are used as inputs to an equalizer algorithm that may be used to reduce distortion of the data signal sent over the primary channel.
