摘要： In macro/RRH setups, channel state information reference signals (CSI-RS) and demodulation reference signals (DM-RS) may be used to decouple control and data transmission. Data transmission (e.g. for LTE Rel 10 and beyond) may be based on CSI-RS and DM-RS, while control may be received from a different set of cells or TxPs via CRS. Certain aspects of the present disclosure introduce a reporting framework, in which configuration of data-serving cells/TxPs may be carried out based on CSI-RS. In certain aspects, a new concept of CSI-RS groups, i.e., a set of CSI-RS ports that a UE considers as one group for precoding matrix indicator (PMI)/channel quality indicator (CQI)/rank indicator (RI) reporting, may be defined.
摘要翻译：在宏/ RRH设置中，信道状态信息参考信号（CSI-RS）和解调参考信号（DM-RS）可用于去耦合控制和数据传输。数据传输（例如，对于LTE Rel 10及其以外）可以基于CSI-RS和DM-RS，而可以经由CRS从不同的小区集合或TxP接收控制。本公开的某些方面引入了报告框架，其中可以基于CSI-RS来执行数据服务小区/ TxP的配置。在某些方面，CSI-RS组的新概念，即UE认为一组用于预编码矩阵指示符（PMI）/信道质量指示符（CQI）/秩指示符（RI）报告）的一组CSI-RS端口，可以被定义。

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： Techniques for adjusting transmit timing of base stations and user equipments (UEs) in a wireless network are described. In one operating scenario, a femto base station communicates with a femto UE, and a macro base station communicates with a macro UE located within the coverage of the femto base station. In an aspect, the transmit timing of the femto base station may be delayed relative to the transmit timing of the macro base station, e.g., to time align downlink signals from the femto and macro base stations at the femto and macro UEs. In another aspect, the transmit timing of the femto UE may be advanced relative to the transmit timing of femto base station by an amount larger than twice the propagation delay between the femto UE and the femto base station, e.g., to time align uplink signals from the femto and macro UEs at the femto base station.

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： 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： Blank subframe link design uses reduced bandwidth either explicit or derived for Closed Subscriber Group (CSG) cell interference mitigation, enabling a non-allowed User Equipment (UE) to co-exist with CSG cells on the same carrier. One could specify UL blank subframes to orthogonalize non-allowed UE and allowed UE transmissions on UL either via explicit UL blank subframe definition or derived from DL blank subframe definition. Scheduling can orthogonalize data transmissions. A femto cell temporarily reducing uplink bandwidth can mitigate uplink control channel residual interference from a non-allowed UE. A relay configures RACH occasion to coincide with non-blank UL subframes as much as possible. UE knowledge of RACH occasion is sufficient to start RACH and hand over procedure. RACH occasions with 10ms periodicity are supported by assigning all odd/even uplink HARQ interlaces to relay. RACH occasions with 20ms periodicity are supported by assigning any of the 1/4 UL HARQ interlaces to relay.
