Abstract: Systems and methods are described to communicate information that specifies bundling of packets and to respond to the bundling in a wireless communication environment. A user equipment (UE) performs bundling of data packets without reliance on a radio resource grant. The UE can generate a bundling report comprising information that specifies at least in part the bundling and transmits the bundling report to a base station. The information can convey a number of bundled data packets; a number of unbundled data packets at the user equipment; an amount of bundled data at the mobile device; or a combination thereof. The UE can transmit the bundling report in accordance with a preconfigured delivery mode or can receive from the base station an indication of a delivery mode to transmit the bundling report. The base station can utilize the information conveyed in the bundling report to schedule radio resource(s).

Abstract: Channel estimates respectively associated with OFDM pilot symbols are used to estimate additional parameters such as change in channel phase over time, change in channel phase over frequency, and frequency selectivity.

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 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: Certain aspects of the present disclosure propose techniques for bundling and ciphering service data units (SDU) in the packet data convergence protocol (PDCP) layer. The proposed techniques increase the data rate of the communication system. At the transmitter side, the PDCP layer may bundle SDUs and cipher each SDU individually before submitting them to a lower layer. At the receiver-side, the PDCP layer may unbundle and decipher the SDUs before submitting them to higher layers.

Abstract: Certain aspects of the present disclosure provide a technique for pre-bundling the received service data units (SDU) into an SDU bundle in a first communication layer before receiving a scheduling information from a second communication layer and adjusting the SDU bundle when the scheduling information is received.

Abstract: Techniques for bundling and ciphering data prior to transmission are described. In an exemplary design, a transmitting entity receives a plurality of service data units (SDUs) from an upper layer, assigns sequential sequence numbers to the SDUs, and bundles the SDUs into a single protocol data unit (PDU). In one design, the transmitting entity generates a single count value based on a sequence number of a designated SDU (e.g., the first SDU) in the PDU and ciphers all SDUs based on the single count value. In another design, the transmitting entity ciphers each segment of at least two SDUs in the PDU based on a count value for that segment. The transmitting entity generates a header with at least one sequence number and possibly length and/or other information for the SDUs. The transmitting entity forms the PDU with the header and the SDUs and passes the PDU to a lower 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: A FAWNA that allows high-speed mobile connectivity by leveraging the speed of optical networks. Specifically, SIMO FAWNA, which comprises a SIMO wireless channel interfaced with a fiber channel through wireless-to-optical interfaces. Received wireless signal at each interface are sampled and quantized prior to transmission. The capacity of the FAWNA approaches the capacity of the architecture exponentially with fiber capacity. It is also shown that for a given fiber capacity, there is an optimal method of operating wireless bandwidth and number of interfaces. An optimal method to divide the fiber capacity among the interfaces is shown, which ensures that each interface is allocated a rate so that noise is dominated by front end noise rather than by quantization distortion. A method is also presented in which, rather than dynamically changing rate allocation based on channel state, a less complex, fixed rate allocation may be adopted with very small loss in performance.

Abstract: Methods and apparatus which reduce or completely eliminate non-shift based divisions as part of estimating transmitted symbols and/or generating slicing parameters corresponding to two symbol transmission streams in a wireless communication system are described. A linear least squares error estimation filtering module performs symbol estimations and/or slicing parameter generation while avoiding non-shift based division operations. The linear least squares estimation module generates intermediate parameters, and implements equations which facilitate symbol estimation utilizing shift based divisions while avoiding non-shift based divisions.

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.

Abstract: Systems and methodologies are described that facilitate dividing scheduling algorithms into background and foreground aspects capable of simultaneously servicing a multiplicity of disparate flows in wideband communications networks. The systems provided herein arbitrarily select prospective time horizons, generate optimal bandwidth allocation targets based on a plurality of flows observed by the system, and utilizes the optimal bandwidth targets to assign flows to users over the entirety of the prospective time horizon.

Abstract: Systems and methodologies are described that facilitate scheduling best effort flows in broadband or wideband wireless communication networks. The systems can include devices and/or component that effectuate associating utility functions to multiple disparate flows based on traffic conditions extant in the wireless system, ascertaining the average rate at which the flow has been serviced in the past, and utilizing the utility function associated with the flow or the average rate that the flow has been serviced in the past to optimally schedule the flow.

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.
