Abstract: Methods and apparatuses are described herein for providing a single-bit hybrid automatic repeat request (HARQ) feedback and a multi-bit HARQ feedback in a wireless transmit/receive unit (WTRU). For example, a WTRU may receive, via a physical downlink control channel (PDCCH), downlink control information (DCI). The DCI may include a field that indicates a code block group (CBG) based retransmission for at least one transport block (TB). On a condition that the DCI does not include the field, the WTRU may transmit, via a physical uplink control channel (PUCCH), a single-bit HARQ feedback for a TB-based retransmission. On a condition that the DCI includes the field, the WTRU may transmit, via the PUCCH, the multi-bit HARQ feedback for the CBG-based retransmission. The WTRU may be configured to provide the single-bit HARQ feedback for the TB-based retransmission and a multi-bit HARQ feedback for the CBG-based retransmission.

Abstract: ePDCCH may be provided. For example, a WTRU may receive a configuration for monitoring an ePDCCH resource. Based on the configuration, the WTRU may be configured to monitor and may monitor the ePDCCH resource on a particular subframe. Additionally, a WTRU may derive an aggregation level for a subframe associated with an aggregation level number NAL. The WTRU may transmit or monitor an ePDCCH using the aggregation level associated with the NAL for the subframe. A WTRU may also receive a reference signal. The WTRU may then determine the type of reference signal received. The WTRU may perform a demodulation of the PDSCH or ePDCCH using a demodulation timing based on the determined type. The ePDCCH or PDSCH may also be monitored or received by identifying a demodulation reference timing implicitly based on a location of one or more ePDCCH resources where the WTRU may receive DCI.

Abstract: A method and apparatus are described for controlling uplink (UL) transmission power. A wireless transmit/receive unit (WTRU) may receive a configuration of UL subframe sets and maintain a plurality of transmit power control (TPC) command accumulator values that correspond to respective ones of the UL subframe sets. The WTRU may receive a TPC command in a subframe n of a downlink (DL) transmission, determine a subframe n+k of a UL transmission that the received TPC command corresponds to, determine which of the UL subframe sets the UL transmission subframe n+k belongs to, and adjust a TPC command accumulator value that corresponds to the determined UL subframe set to determine power of the UL transmission when transmitting in the UL transmission subframe, where n is an integer, and k is an integer greater than zero.

Abstract translation: 可以提供ePDCCH。 例如，WTRU可以接收用于监视ePDCCH资源的配置。 基于该配置，WTRU可以被配置为监视并监视特定子帧上的ePDCCH资源。 另外，WTRU可以导出与聚合级数NAL相关联的子帧的聚合级别。 WTRU可以使用与子帧的NAL相关联的聚合级别来发送或监视ePDCCH。 WTRU还可以接收参考信号。 WTRU然后可以确定所接收的参考信号的类型。 WTRU可以使用基于所确定类型的解调定时来执行PDSCH或ePDCCH的解调。 还可以通过基于WTRU可以接收DCI的一个或多个ePDCCH资源的位置隐含地识别解调参考定时来监视或接收ePDCCH或PDSCH。

Abstract: A wireless transmit/receive unit (WTRU) may receive a first signal including a primary synchronization signal (PSS) and a secondary synchronization signal (SSS) in a cell. The PSS and SSS may use a first numerology. Further, the first numerology may have a first subcarrier spacing, while other resources of the cell at a same time as the PSS or the SSS use a second numerology with a different subcarrier spacing than the first numerology. In addition, the WTRU may synchronize to a timing of the cell based on the PSS and SSS. Also, the WTRU may receive a second signal in the cell, and the second signal may use the second numerology. Moreover, the WTRU may transmit user data. In a further example, the WTRU may search a frequency raster for the PSS and the SSS.

Abstract: A wireless transmit/receive unit (WTRU) may receive a first signal including a primary synchronization signal (PSS) and a secondary synchronization signal (SSS). The PSS and SSS may be received in a resource block of a cell and the resource block may have a first numerology. Further, the first numerology may have a first subcarrier spacing, while other resources of the cell at a same time as the resource block may have a second numerology with a different subcarrier spacing than the first numerology. In addition, the WTRU may determine synchronization based on the PSS and SSS. Also, the WTRU may receive a second signal in the cell, and the second signal may have the second numerology. Moreover, the WTRU may transmit user data. In a further example, the WTRU may search a frequency raster for the PSS and the SSS.
