摘要： Aspects disclosed herein relate to channel and interference estimations in a multiple transmission point environment including an eNB and RRHs. In the disclosed aspects, one or more transmission points can signal to a UE to measure channel state conditions based on a first and a second resource pattern. The UE may receive the signaling and perform interference estimation based at least in part on the first resource pattern, and channel estimation based at least in part on the second resource pattern. The UE may generate a channel state report based on the interference and channel estimations, and transmit the channel state report to a transmission point. The eNB may employ the received channel state report in scheduling one or more resources for use by the UE, and may select or adjust network traffic on the first and the second resource pattern, to affect the resulting channel and interference estimation.

摘要： Acknowledgment bundling has been defined for Long Term Evolution (LTE) Time Division Duplex (TDD) systems due to asymmetric DL/UL partitioning. In the case of Frequency Division Duplex (FDD) with a limited uplink (UL) duty cycle, there may be asymmetry associated with a downlink transmission and an associated uplink acknowledgment. For example, there may be a physical downlink shared channel (PDSCH) and a physical uplink control channel (PUCCH) hybrid automatic repeat request acknowledgment (HARQ-ACK) asymmetry. Interference between downlink and uplink transmissions may be a factor contributing to the limited UL duty cycle in an FDD system. For an FDD system having a limited mobile transmission duty cycle, both DL and UL performance may be significantly degraded without proper mitigation techniques. According to certain embodiments of the present disclosure, various HARQ and scheduling techniques may be utilized for minimizing loss due to the limited UL duty cycle.
摘要翻译：由于不对称的DL / UL划分，已经为长期演进（LTE）时分双工（TDD）系统定义了确认捆绑。在具有有限上行链路（UL）占空比的频分双工（FDD）的情况下，可能存在与下行链路传输和相关联的上行链路确认相关联的不对称性。例如，可以存在物理下行链路共享信道（PDSCH）和物理上行链路控制信道（PUCCH）混合自动重传请求确认（HARQ-ACK）不对称性。下行链路和上行链路传输之间的干扰可能是导致FDD系统中限制的UL占空比的因素。对于具有有限移动传输占空比的FDD系统，如果没有适当的缓解技术，DL和UL性能可能会显着降低。根据本公开的某些实施例，可以利用各种HARQ和调度技术来最小化由于有限的UL占空比导致的损失。

摘要： Methods and apparatus for performing radio resource management (RRM) measurements in a heterogeneous network (HetNet) are provided in an effort to prevent failure of RRM measurement procedures in a dominant interference scenario. Several alternatives are provided for determining particular resources (e.g., subframes) to use for performing the RRM measurements, wherein the particular resources are based on cooperative resource partitioning between cells of the HetNet, wherein the cells may be of different types (e.g., macro, pico, or femto cells). These alternatives include, for example: (1) intra-frequency or intra-RAT (radio access technology) alternatives, which may involve transmitting resource partitioning information (RPI) in or deriving non-serving cell RPI based on the serving cell's RPI, as well as (2) inter-frequency or inter-RAT alternatives, where the RRM measurements may be performed during a measurement gap.

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.

摘要： Systems and methodologies are described that facilitate providing hybrid cell access points that can support closed subscriber groups (CSG) while providing at least a minimum level of service to wireless devices excluded from the CSG. Hybrid cell access points can allow non-member wireless devices to camp and receive paging signals. Upon receiving a request for resources from non-member wireless devices, hybrid cell access points can handover the non-member wireless devices to an access point that can serve the non-member wireless devices, provide a portion of resources compared to a disparate portion provided to member wireless devices, and/or the like. In addition, hybrid cell access points can vary levels of service and downlink transmission power to provide load balancing for access points. Varying levels of service and downlink transmission power can facilitate additional functionality, such as reducing transmission power to serve member devices while mitigating interference to non-member devices.
摘要翻译：描述了系统和方法，其便于提供可以支持封闭用户组（CSG）的混合小区接入点，同时向从CSG排除的无线设备提供至少最低级别的服务。混合小区接入点可以允许非成员无线设备驻留和接收寻呼信号。在从非成员无线设备接收到对资源的请求时，混合小区接入点可以将非成员无线设备切换到可以服务非成员无线设备的接入点，提供与提供的不同部分相比的一部分资源到成员无线设备和/或类似物。此外，混合小区接入点可以改变服务等级和下行链路传输功率，以为接入点提供负载均衡。不同级别的服务和下行链路传输功率可以促进附加的功能，例如降低传输功率以服务于成员设备，同时减轻对非成员设备的干扰。

摘要： A plurality of transmission patterns for pilot systems transmitted from a mobile station or base station are provided. Depending upon the frequency selectivity and/or the time selectivity of the channel between the mobile station and the base station, an appropriate pattern is selected. The selected pattern allows for improved receipt of the pilot symbols.

摘要： Systems and methodologies are described that facilitate resource scaling for inter-access point fairness in a wireless communication system. As described herein, an offered load of an access point can be determined based on one or more loading metrics relating to associated terminals, throughput, data rate, quality of service (QoS), or the like. Based on the determined offered load of an access point, resources used by the access point and/or power utilized for communication over those resources can be scaled based on a comparison of the offered load of the access point to a nominal or default offered load. Centralized techniques for resource scaling are described herein, wherein one or more centralized controllers coordinate resource scaling with respective access points via backhaul messaging. In addition, distributed techniques for resource scaling are described herein, wherein neighboring access points communicate with each other via over-the-air messaging to determine a local optimal resource apportionment.
