Each mobile station measures only CQIs of the PRBs that form the active set designated by the base station and informs the base station of the measurements. That can reduce the load on the mobile station and also reduce the amount of information for informing the CQIs, thus, the uplink overhead can be also reduced. |

Resource utilization measurements for heterogeneous networks
Interference issues between wireless network devices are mitigated. An evolved node B (eNodeB) may experience higher cell load or higher interference when serving user equipment (UEs) that are operating in an cell range extension (CRE) area in which the UEs are strongly affected by aggressor eNodeBs. An eNodeB experiencing higher cell load or serving user equipments (UEs) under higher interference generally requests an interfering/aggressor eNodeB to repartition some of its resources. Repartitioning of resources, however, may have a negative impact on the eNodeB serving CRE area UEs. In one aspect, a new measurement of utilization accounts for CRE status and differentiates between protected and unprotected resources, such as subframes. |

Data packet routing
Among other things, one or more techniques and/or system are provided for routing a data packet. Because the data packet may correspond to a source device having an address on a first network that may be similar to an address of a second device on a second network, the data packet may be translated to create a transformed data packet that may be distinguishable from data packets of the second device. For example, the data packet may be translated from a first address format, such as IPv4, to a second address format, such as IPv6, to create a transformed data packet. The transformed data packet may comprise a prefix that may distinctly identify the source device during routing. In this way, the transformed data packet may be identifiable as corresponding to the source device during routing through a network to a destination device. |

Multicast to unicast conversion technique
A technique allows stations to utilize an equal share of resources (e.g., airtime or throughput). This prevents slow stations from consuming too many resources (e.g., using up too much air time). Fairness is ensured by selective dropping after a multicast packet is converted to unicast. This prevents slow stations from using more than their share of buffer resources. Multicast conversion aware back-pressure into the network layer can be used to prevent unnecessary dropping of packets after multicast to unicast (1:n) conversion by considering duplicated transmit buffers. This technique helps achieve airtime/resource fairness among stations. |

Multicast implementation in a link state protocol controlled ethernet network
Forwarding state is installed for sparse multicast trees in a link state protocol controlled Ethernet network by enabling intermediate nodes to install state for one or more physical multicast trees, each of which may have multiple logical multicast trees mapped to it. By mapping multiple logical multicasts to a particular physical multicast, and installing state for the physical multicast, fewer FIB entries are required to implement the multiple multicasts. Mapping may be performed by destination nodes before advertising membership in the physical multicast, or may be performed by the intermediate nodes before installing state when a destination node advertises membership in a logical multicast. Intermediate nodes will install state for the physical multicast tree if they are on a shortest path between a source and at least one destination of one of the logical multicasts that has been mapped to the physical multicast. |
