  • Patent number: 10349438
    Abstract: Channel availability is uncertain when employing an unlicensed carrier. In particular, it may be difficult to schedule grants in advance because of the uncertainty associated with future channels availability. Accordingly, scheduling UL and/or DL grants exclusively using self-scheduling or exclusively using cross-carrier scheduling for utilizing an unlicensed carrier may result in wasted communication opportunities. Aspects disclosed herein whereby an eNB may use licensed and unlicensed carriers to communicate downlink grants and uplink grants for an unlicensed carrier to a UE. In one aspect, the eNB may use an unlicensed carrier to communicate downlink grants for downlink communication on the unlicensed carrier, and may use a licensed carrier to communicate uplink grants for uplink communication on the unlicensed carrier.

  • Patent number: 10257092
    Abstract: One embodiment provides a system that facilitates forwarding of packets with variable length names. During operation, the system receives a packet with a hierarchically structured variable length identifier (HSVLI) which comprises contiguous name components ordered from a most general level to a most specific level. The system performs a longest prefix match lookup by selecting an entry from a first data structure of entries. The entries indicate a name component, forwarding information for the name component, and a plurality of entry identifiers that chain an entry to another entry. If a size of the name component is less than or equal to a predetermined threshold, the system selects an entry based on the name component. If the size is greater, the system selects an entry based on a compressed key which can be a hash of the name component. The system also resolves collisions associated with the selected entry.

  • Patent number: 10251103
    Abstract: Traffic associated with user equipment that are served by a first radio access network is steered to a second radio access network based on a rate of congestion criterion. Network load is monitored by an access point to determine rate of congestion data associated with the access point. As an example, the rate of congestion represents a change in network load of the access point over a defined time period. The rate of congestion data is then transmitted to one or more neighboring access points that can utilize the rate of congestion data to facilitate traffic steering, load balancing, and/or neighbor relationship management.
