摘要： A method of wireless communication determines a UE interference condition during handover. A target cell receives information that indicates an interference condition of a user equipment (UE). Prior to completing handover, the target cell determines an expected UE interference condition that will arise after completing the handover of the UE at a target base station. The information can be determined based on a message from the UE. The UE message may indicate which cell is the strongest, indicate the interference condition at both the source and target cells, or only provide a measurement of the strongest cell. Based on the UE measurements, the target eNodeB may schedule the UE on resources based on the expected interference condition at the UE that may arise after the handover.

摘要： Methods and apparatus for partitioning resources for enhanced inter-cell interference coordination (eICIC) are provided. Certain aspects involve broadcasting a message indicating time-domain resource partitioning information (RPI), where a user equipment (UE) may be operating in idle mode. With the RPI, the UE may be able to identify protected resources with reduced/eliminated interference from neighboring cells. The RPI in this broadcasted message may be encoded as a bitmap as an alternative or in addition to enumeration of the U/N/X subframes. Other aspects entail transmitting a dedicated or unicast message indicating the time-domain RPI, where a UE may be operating in connected mode. With the RPI, the UE may be able to determine channel state information (CSI), make radio resource management (RRM) measurements, or perform radio link monitoring (RLM), based on one or more signals from a serving base station during the protected time-domain resources.

摘要： Aspects of the present disclosure may simplify the negotiation of resources by defining and/or using sequences for sets of resources for enhanced inter-cell interference coordination. According to aspects, a configuration of protected resources may have an ordering such that a pattern representing ‘k’ protected resources overlaps with a pattern representing ‘k+1’ protected resources. In an aspect, each pattern may comprise a bitmap with one or more bits set to a value to indicate the one or more protected subframes. In an aspect, a bitmap of a pattern corresponding to ‘k’ protected subframes differs from a bitmap of a pattern corresponding to ‘k+1’ protected subframes by a single bit value. According to aspects, an interfering evolved Node B may limit transmissions during protected subframes based on the selected pattern.

摘要： 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.

摘要： Aspects directed towards measurement procedures in multicarrier operation are disclosed. In a particular aspect, a wireless terminal selects a subset of cells, which include at least one serving cell and at least one non-serving cell. The subset of cells are then evaluated by obtaining a first measurement associated with the at least one serving cell and a second measurement associated with the at least one non-serving cell. A measurement event occurrence, which is based on a comparison between the first measurement and the second measurement, is then monitored. An occurrence of the measurement event triggers a measurement report transmission, which the network then uses to perform handovers. Other disclosed embodiments are directed towards placing a reception band, which include identifying a set of assigned component carriers and placing a reception band within the system bandwidth so that the placement overlaps with at least a portion of the assigned component carriers.
