Abstract: Techniques for supporting operation with enhanced uplink in inactive state are described. A user equipment (UE) may send an access preamble for random access while in an inactive state and may receive a message containing resources allocated to the UE. The allocated resources may be selected by a Node B from a pool of resources pre-allocated to the Node B for the enhanced uplink. The UE may send information (e.g., scheduling information and/or its UE identity) to the Node B using the allocated resources. The UE may receive an acknowledgement addressed to the UE based on the UE identity. The UE may remain in the inactive state and continue to use the allocated resources until they are de-allocated. Alternatively, the UE may transition to an active state and either continue to use the allocated resources or receive an allocation of new resources for the active state.

Abstract: A virtual directory server (VDS) processes requests based on a first hierarchical model while using a backend server operating based on a relational model. In one embodiment, classes representing the tables and columns in the relation model are generated according to a second hierarchical model (class hierarchy). On receiving a directory request for values' corresponding to attributes in the first hierarchical model, tables and columns corresponding to the requested attributes are identified. A query according to the relational model is constructed employing the generated classes (of the second hierarchical model), the query including the identified tables and columns. The query is then executed in the backend server to retrieve the values corresponding to the attributes, and the values are then sent (according to the first hierarchical model) as a reply to the directory request.

Abstract: In a method for reducing interference in wireless communications, a beamforming matrix is determined at a first communication device based on an estimate of a multiple input, multiple output (MIMO) communication channel between the first communication device and a second communication device. Both the first communication device and the second communication device belong to a first wireless network. Alternatively, the beamforming matrix may be generated based on the estimate of the MIMO communication channel and received at the first communication device. The beamforming matrix is used at the first communication device for the purpose of reducing interference to a second wireless network. where the interference is caused by the first communication device transmitting to the second communication device via the MIMO communication channel.
