Abstract: Systems and methodologies are described that facilitate dynamically adjusting scheduling priorities in relation to a combination of delay sensitive flows with delay requirements and best effort flows. The systems and methodologies provide optimal and efficient techniques to enable real time adjustment and assignment of bandwidth for a combination of best effort flows and delay sensitive flows. In particular, the bandwidth allocation is adjusted for each data packet such that delay requirements are met and the remaining bandwidth can be assigned to best effort flows.

Abstract: Systems and methodologies are described that facilitate unbundling and processing partial packet data units (PDU). PDUs can be transmitted at a communication layer and can include partial PDUs of a disparate communication layer. Complete SDUs can be determined in the partial PDU and provided to an upper communication layer. In addition, however, the partial PDU can comprise a partial SDU. Upon receiving a remaining or additional portion of the partial PDU, a remaining or additional portion of the partial SDU can be combined with the partial SDU to create a complete SDU (or a larger portion thereof). Where a complete SDU is created, it can be provided to an upper communication layer. Alternatively, the partial PDU can be combined with the remaining portion of the partial PDU to generate a complete or larger PDU, from which the previously incomplete SDU can be retrieved and provided to an upper communication layer.

Abstract: Systems and methodologies are described that facilitate creating a packet bundle of Internet Protocol (IP) packets that can be utilized for Just-In-Time (JIT) processing and/or offline processing. In general, upon receipt or detection of incoming IP packets, two or more IP packets can be bundled or packaged together to create a packet bundle. Furthermore, the packet bundle can be created based upon a timer in which a maximum size of the packet bundle and a maximum number of IP packets within a packet bundle can be maintained.

Abstract: Certain aspects of the present disclosure provide a technique for bundling the received service data units (SDU) in a first communication layer to generate a protocol data unit (PDU) to pass to a second communication layer. For example, one or more packet data convergence protocol (PDCP) SDUs may be concatenated to generate a PDCP PDU and be sent to a radio link control (RLC) layer in the transmitter side. Similarly, one or more PDCP SDUs may be extracted from a PDCP PDU in the receiver side.

Abstract: Systems and methodologies are described that facilitate enhanced resource scheduling for a wireless communication system. As described herein, packets associated with a common flow that arrive within a predetermined time period following a leading packet associated with the flow can be grouped into respective packet bursts. Subsequently, system bandwidth, transmit power, and/or other communication resources can be scheduled based on an analysis of the respective packet bursts. As provided herein, by analyzing respective packet bursts in lieu of individual packets, computational and resource overhead required for resource scheduling can be significantly reduced. In one example described herein, a resource schedule is determined by selecting one or more flows to be assigned bandwidth from among a plurality of flows based on an analysis of packet bursts respectively associated with the flows. Sufficient bandwidth can subsequently be scheduled for the selected flows for transmission of the respectively associated packet bursts.
