Abstract: Techniques are provided for reducing delay during streaming transmissions. A method may include receiving a stream of Dynamic Adaptive Streaming over HTTP (DASH) data segments (308) at a File Delivery over Unidirectional Transport (FLUTE) packet engine (310 400). The method may include establishing a first group of segments based on the DASH data segments and generating a first table of information. The method may include transmitting the first table (430b) and the first group of segments (430a) and establishing a second group of segments based on the DASH data segments the second group of segments including a partial overlap of DASH data segments included in the first group of segments. The method may include generating a second table of information (430b) and transmitting the second table and a collection of segments (430a) that includes DASH data segments from the second group that were not part of the first group.

Abstract: Information can transfer from a transmitter to a receiver; however, the transmission can consume valuable resources. Therefore, a number of times a transmission is attempted can be tracked and compared against a threshold value. If the transmission occurs too many times - based upon the comparison - then a reset can occur. Tracking can occur for a protocol data unit and/or a control protocol data unit to determine if a reset should occur.

Abstract: METHODS AND APPARATUSES FOR PROCESSING MEASUREMENT GAPS IN A WIRELESS COMMUNICATION SYSTEMIn a wireless communication system, user equipment (UE) is provided, one or more set of rules are provided for the UE to handle the processing during a measurement gap. In some aspects, the gap measurement may be ignored. In some aspects, the processing is stored and handled at a later in time and gap measurements are performed. Depending on the system, the measurements performed during the gaps may be UE implementation dependent, wherein the UE determines whether to perform the measurement for a given gap. In some instances, the UE may not perform measurements during the gap, thereby giving priority to other processing, such as RACH processing. Depending on the type of processing required (DL-SCH, UL-SCH, TTI bundling, RACH or SR), the UE may store requests and process the measurements during the gap or ignore the gap measurement as if there were no gaps.Figure 1

Abstract: Explicit signaling of End of Handover (EoH) advantageously indicates when user equipment (UE) has stopped using Packet Data Convergence Protocol (PDCP) handover mode. Radio Link Control (RLC) Acknowledge Mode (AM) delivers in order ensuring that all reordered packets have been received with no risk of delivering a gap packet when no longer in handover mode that would otherwise cause Hyper Frame Number (HFN) to be out of synchronization. Substantially at a time evolved Base Node (eNB) determines a gap will not be filled, eNB can convey an EoH indication to a served UE and can then deliver the PDCP Service Data Units (SDUs) with gaps to upper layers without delay.

Abstract: Un solo receptor puede agrupar múltiples unidades de datos de protocolo al momento que se originan a partir de diferentes fuentes. Aunque puede ser deseable que se procesen las unidades de datos de protocolo de prioridad mayor, la pérdida de porciones de unidad de datos puede ocasionarle confusión al receptor. Por lo tanto, incluso si una unidad de datos de protocolo de prioridad mayor se transfiere al receptor mientras se está procesando una unidad de datos de prioridad menor, la unidad de prioridad menor puede completarse antes de procesar la unidad de prioridad mayor; consecuentemente, puede haber una menor probabilidad de confusión entre las unidades de datos de protocolo.

Abstract: Systems and methodologies are described that facilitate scheduling for transmissions of status messages, such as Packet Data Convergence Protocol (PDCP) status messages or Radio Link Control (RLC) acknowledgement messages, in a wireless communication system. As described herein, at time periods at which transmission of status messages is desired, respective status signaling associated with a set of radio bearers, logical channels, or the like can be configured to be transmitted prior to conducting transmission(s) of data. By doing so, a receiving entity can obtain the status signaling at substantially the earliest possible opportunity, allowing the receiving entity to avoid unnecessary bandwidth and/or memory expenditure associated with re-transmissions of information. As further described herein, status information can be prioritized by the use of separate status bearers, respective indicators provided within information elements queued on respective radio bearers, a maintained list of respective radio bearers containing status information, and other similar mechanisms.

Abstract: An efficient use of downlink (DL) air-interface bandwidth during handoff of user equipment from a source cell to a target is provided. In conjunction with a handoff message to ensure receipt, expedited status exchanges are provided so that initial communications do not require a subsequent retransmission of duplicate data. A method for transmitting a dedicated Random Access Channel (RACH) preamble and cell information, receiving a RACH from the user equipment to start communication, and transmitting a handover message and a radio link control (RLC) status message or an UL grant in response to receiving the RACH is provided. Also, a method for receiving a handover message and target cell information from a source cell to start handover negotiations, initiating communication with target cell using the target cell information, receiving a handover message and (RLC) status message, and using the received information to approximate status reporting is provided.
