  • Patent number: 10225130
    Abstract: A network component for classifying at least one IP flow for efficient quality of service realization in a network, where in one embodiment the network component includes a unit for detecting at least one IP flow from at least one IP packet. Upon detection of the at least one IP flow, the unit obtains predefined information from the at least one IP packet to determine a quality of service requirement that is associated with the at least one IP packet. The unit creates at least one other IP flow by multiplexing a plurality of IP packets with the same quality of service requirement into the other IP flow or demultiplexing the plurality of IP packets with different quality of service requirements into other IP flows, each of the other IP flows having a different quality of service requirement.

  • Patent number: 9893839
    Abstract: An approach includes detecting failure of an error detection scheme relating to transmission of data units of a transport block. A negative acknowledgement message is generated in response to the detection of the failure. The negative acknowledgement message is forwarded to a radio link controller for discarding one or more of the data units.

  • Patent number: 8422438
    Abstract: The invention relates to the design of power sequences for use in a group of sub-areas of a wireless communication system. Each power sequence defines for one of the sub-areas transmission power values for transmissions using a respective one of a plurality of medium access units. For each of the sub-areas of the group, reception quality values are determined for transmissions between an access station serving the sub-area and mobile stations located at an edge of the sub-area. The reception quality values allow meeting system. The reception quality values are then converted for each of the sub-areas into transmission power values of a power sequence.

  • Patent number: 8411627
    Abstract: An approach is provided to support resource allocation of broadcast or paging control channels. It is determined whether resource is allocated for a logical control channel. One or more fields of a physical downlink control channel is defined to signal the resource allocation for the logical control channel. The physical downlink control channel has a first format to support transmission of data over a downlink channel, and a second format that includes the one or more fields to support allocation of the logical control channel.

  • Patent number: 8341480
    Abstract: An approach is provided for utilizing implicit negative acknowledgement. A determination is made that a user equipment is out of synchronization (e.g., with respect to the uplink). A control signal specifying timing alignment information is generated for transmission to the user equipment. An implicit negative acknowledgement corresponding to retransmission of data is declared if an acknowledgement is not received within a predetermined time interval.

  • Patent number: 7852805
    Abstract: The specification and drawings present a new method, system, apparatus and software product for varying a length of a radio link ID (RLID) of a user equipment for resource allocation in mobile communication systems. This allows the system to employ shorter RLID lengths than is necessary if all user equipments (UEs) in the active mode are uniquely identified simultaneously, thus providing considerable savings in the signaling resource on the physical layer.
