Abstract: Systems and method are specified to improve the reception of UL transmission, for example in power or coverage limited situations. A WTRU may modify procedures to increase the available signal energy for reception at an eNB and/or to make more efficient use of the available signal energy at the receiver for processing UL transmissions. Example methods for increasing UL link coverage may include modifying HARQ timing (e.g., shorter HARQ), using longer TTIs, use of dedicated PUSCH allocations, use of new PUSCH modulations, enhanced reference signal design, UL macro diversity reception for PUSCH, utilizing protocol reduction techniques, ensuring in-order packet delivery, and/or utilizing a configuration for coverage limited/power limited modes of operation. The proposed methods may be applied individually or in any combination.

Abstract: Channel state information is reported in periodic and aperiodic reports for multiple component carriers or serving cells. Channel state information may be reported for a subset of aggregated downlink carriers or serving cells. For an aperiodic report, the carrier(s)/serving cell(s) for which channel state information is reported may be determined based on the request for the aperiodic report. A report collision may occur in a subframe between a periodic CSI report for a first serving cell and a report for a second serving cell. A priority rule may be used to resolve the report collision.

Abstract: Systems and method are specified to improve the reception of UL transmission, for example in power or coverage limited situations. A WTRU may modify procedures to increase the available signal energy for reception at an eNB and/or to make more efficient use of the available signal energy at the receiver for processing UL transmissions. Example methods for increasing UL link coverage may include modifying HARQ timing (e.g., shorter HARQ), using longer TTIs, use of dedicated PUSCH allocations, use of new PUSCH modulations, enhanced reference signal design, UL macro diversity reception for PUSCH, utilizing protocol reduction techniques, ensuring in-order packet delivery, and/or utilizing a configuration for coverage limited/power limited modes of operation. The proposed methods may be applied individually or in any combination.

Abstract: Methods and apparatus for multiple-input multiple-output (MIMO) transmissions are disclosed. A base station may precode wireless transmit/receive unit (WTRU)-specific reference signals and data that are transmitted to a WTRU using a randomly selected precoder. The precoder may be selected based on a predefined precoder selection sequence or by the base station. A different precoder may be applied to different resource blocks (RBs). In addition, a large delay cyclic delay diversity (CDD) or discrete Fourier transform (DFT) spreading may be applied on the WTRU-specific reference signals and the data. For heterogeneous deployed antennas, spatial diversity gain is achieved by dynamically scheduling resources between transmission points. A hopping scheme may be applied across the transmission points as the resources are dynamically partitioned between the transmission points. A different randomly selected precoder may be applied to each RB transmitted from a different transmission point.
Abstract translation: 公开了用于多输入多输出（MIMO）传输的方法和装置。 基站可以使用随机选择的预编码器对无线发射/接收单元（WTRU）特定的参考信号和数据进行预编码，所述参考信号和数据被发送到WTRU。 可以基于预定义的预编码器选择序列或基站来选择预编码器。 不同的预编码器可以应用于不同的资源块（RB）。 此外，可以对WTRU特定的参考信号和数据应用大的延迟循环延迟分集（CDD）或离散傅立叶变换（DFT）扩展。 对于异构部署的天线，通过在传输点之间动态调度资源来实现空间分集增益。 当资源在传输点之间动态分配时，可以跨传输点应用跳频方案。 可以将不同的随机选择的预编码器应用于从不同传输点发送的每个RB。
