    Abstract: Mitigation of inter-base station resynchronization loss in wireless networks including contention-based shared frequency spectrum is discussed. Aspects of such mitigation provide for base stations entering into an idle mode when a transmission opportunity occurs in a radio frame of the next resynchronization occasion. Additional aspects provide for the base station to signal a flexible listen before talk (LBT) frame length to the user equipment (UE), either with or without explicit signaling of the downlink-uplink division. Further aspects provide for the base station to signal a reset indication to UEs that will prompt the UEs to monitor for downlink channel reserving signals prior to the current LBT frame ending by the resynchronization occasion.

    Abstract: 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.

    Abstract: Techniques are described for managing QoS parameters of a bearer for which at least a portion of bearer data is served over a WLAN radio access technology. According to these techniques, a first device may identify a first set of one or more QoS parameters for serving a bearer over a wireless wide area network (WWAN). The first device may also determine a second set of one or more QoS parameters for serving the bearer over the WLAN based on an association between the first set of QoS parameters and the second set of one or more QoS parameters.

    Abstract: The disclosure provides a method and system for requesting access to resources for uplink communications in unlicensed spectrum. In particular, a user equipment (UE) may detect one or more of a first type of data or a second type of data to be transmitted to a base station (BS). The UE may then determine if a first type of physical random access channel (PRACH) resource is available for transmitting one or more of the first type of data or the second type of data to the BS. If the first type of PRACH resource is available, then the UE may transmit one or more of the first type of data or the second type of data using the first type of PRACH resource. If the first type of PRACH resource is not available, then the UE may transmit the second type of data using a second type of PRACH resource.

    Abstract: Techniques for managing downlink transmissions from a base station to multiple UEs over aggregated LTE and WLAN links are provided. The base station may jointly assign resources for transmitting downlink data during a scheduling instance. The resource assignment may include a prioritization based on channel conditions and system throughput when the links are considered jointly. In accordance with the joint resource assignment, the base station may build packets for the downlink transmission at an aggregating layer which, for example, may be coupled to media access control (MAC) elements associated with the respective links. The base station may then transmit the packets to at least a subset of the UEs based on the joint resource assignment.
