    摘要: A network device may make a determination that a first backhaul connection, which serves a first base station, is congested and that a second backhaul connection, which serves a second base station, is not congested. This determination may be made based on a first periodic data cap imposed (on the first backhaul connection, a traffic load on the first backhaul connection, a second periodic data cap imposed on the second backhaul connection, and a traffic load on the second backhaul connection. In response to the determination, the network device may configure a value of a cellular communication parameter utilized by one or both of the base stations. The configuration may comprise periodic adjustments of the value of the cellular communication parameter. The periodic adjustments may cause one or more mobile devices to be cyclically handed-over between the first base station and the second base station.

    摘要: 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.

    摘要: 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.

    摘要: 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.

    摘要: Methods and apparatus for avoiding overflow and underflow conditions through the determination of appropriate scaling factors in signal estimation processing in a receiver are described. The receiver estimates transmitted symbols from one or more transmitter device antennas, while avoiding underflow and overflow conditions. A pilot based noise estimate and an estimated expected received signal power, corresponding to a transmit antenna, are used to generate an SNR corresponding to the transmit antenna. The generated SNR is used to determine, e.g., select from a fixed size set of predetermined scale factor values, a scale factor to be used for estimation processing associated with the transmit antenna. In some embodiments, the generated scaling factors are used by a fixed point processing linear least squares error estimation module. Scaling factor determination is performed at a rate which is slower than the rate at which symbols are received from a transmit antenna.

    摘要: 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.
