Abstract: Aspects of the present disclosure are directed to a user equipment an RNC or an application operable in a wireless communications network and methods in which an apparatus for wireless communication is configured to transfer data for a user equipment via a first user plane connection in a first radio access network. If the data transferred via the first user plane connection satisfies a trigger condition the apparatus is configured to initiate a handover procedure of transferring the user equipment to a second user plane connection in a second radio access network.

Abstract: The present disclosure presents methods and apparatuses for improved data rates in a wireless communications environment wherein a user equipment (UE) may receive and transmit signals from a plurality of network entities (NodeBs) which are controlled by separate radio network controllers (RNCs). For example the disclosure presents a method of wireless communication in a multiflow environment which includes establishing a first flow between a serving radio network controller (S RNC) and a first network entity wherein the S RNC controls the first network entity. The method also includes establishing a second flow between the S RNC and a second network entity which is controlled by a drift radio network controller (D RNC). Furthermore the method includes transmitting data to the UE via both the first flow and the second flow.

Abstract: A method and apparatus for wireless communication may provide for reduced data loss during mobility events in a wireless communication network capable of downlink carrier aggregation. Some aspects of the disclosure provide for maintaining data corresponding to a flow in at least one buffer at a Node B when the Node B acts as a serving cell for the same UE both before and after a serving cell change. Another aspect of the disclosure provides for transferring buffered data from a Node B that acts as a serving cell for a UE before a serving cell change to a Node B that acts as a serving cell for the UE after the serving cell change.

Abstract: Initiating and operating a high speed dedicated physical control channel HS DPCCH to report a current channel quality indicator CQI. A user equipment UE may receive a high speed sharedcontrol channel HS SCCH order from a Node B triggering a feedback response (i.e. a feedback regarding CQI and/or ACK/NACK on the HS DPCCH channel). The UE may perform a physical random access channel (PRACH) procedure in response to receiving the order and may also initiate a collision resolution procedure. The user equipment may transmit a current channel quality indicator (CQI) of the user equipment on a high speed dedicated physical control channel (HS DPCCH) prior (before beforehand) to achieving collision resolution (i.e. a result from the collision resolution procedure).

Abstract: Apparatus and methods of mobility management include identifying a target cell as an active set candidate. The apparatus and methods further include determining that a trigger adjustment condition exists, wherein the trigger adjustment condition triggers an adjustment of a timing value that indicates a sending time of a target cell add message to a serving cell. Moreover, the apparatus and methods include sending the target cell add message including the target cell to the serving cell based on determining that the trigger adjustment condition exists.

Abstract: Adaptive De-Jitter Buffer for Voice over IP (VoIP) for packet switched communications. The de-jitter buffer methods and apparatus presented modify the playback of packets dependent upon whether silence periods are detected inter-sentence or intra-sentence to optimize voice quality in a communication system. In one example, a de-jitter buffer determines the length of at least one silence period associated with a plurality of received packets and determines a time to transmit a portion of the packets based on the determined length of the silence period. In another example, a silence characterizer unit performs this function.

Abstract: Methods, apparatus, systems and computer program products are defined that provide for in-order deliver of data packets during hand-off. The aspects provide for in-order delivery at Forward Link Serving eBS/Data Attachment Point (FLSE/DAP) switch and Reverse Link Serving eBS/Data Attachment Point (RLSE/DAP) switch. As such, present aspects provide for significant improvement in the throughput of applications, such as applications relying on Transmission Control Protocol (TCP), during handoff, in such networks as Ultra Mobile Broadband (UMB) and the like.

Abstract: Providing for improved wireless communications for user equipment (UE) in a semi-active state is described herein. By way of example, a base station can employ particular wireless channel resources, monitored by a UE in a CELL_FACH state for instance, to trigger channel feedback information from the UE. The trigger can comprise an explicit order instructing the UE to provide data in response, or can include a portion of downlink traffic targeting the UE, where the UE is configured to respond in a suitable manner to receipt of traffic data. The UE can maintain the CELL_FACH state in receiving to and responding to the trigger, and can further receive subsequent traffic data in such state. Accordingly, the subject disclosure provides for improved efficiency and reliability in semi-active state wireless communications.
