    Abstract: Time tracking in current communication systems may be traditionally based on common reference signals (CRS). However, in certain communication systems, CRS-based time tracking may be impossible to implement due to an absence of CRS in certain subframes or carriers. CRS-based time tracking may also be inappropriate to implement in certain communication systems such as a coordinated multipoint (CoMP) system where control and data may arrive from different cells, and therefore, a UE may assume a wrong cell for CRS-based time tracking. Accordingly, methods, apparatuses, and computer program products for wireless communication are provided in which additional UE specific reference signals (UE-RS) and/or channel state information reference signals (CSI-RS) are made available to the UE so that the UE may have improved channel estimation and/or time tracking performance.

    Abstract translation: 当前通信系统中的时间跟踪传统上可以基于公共参考信号（CRS）。 然而，在某些通信系统中，由于某些子帧或载波中没有CRS，基于CRS的时间跟踪可能是不可能实现的。 基于CRS的时间跟踪也可能不适于在诸如协调多点（CoMP）系统的某些通信系统中实现，其中控制和数据可以从不同的小区到达，因此，UE可以假设用于基于CRS的时间跟踪的错误小区 。 因此，提供了用于无线通信的方法，设备和计算机程序产品，其中附加的UE特定参考信号（UE-RS）和/或信道状态信息参考信号（CSI-RS）对于UE是可用的，使得UE 可以改善信道估计和/或时间跟踪性能。

    Abstract: A method, a computer program product, and an apparatus for determining retransmission feedback resources are provided. An apparatus receives a downlink resource assignment over a control channel and obtains an offset related to a region for retransmission feedback resources. The offset is determined based on a type of the control channel. The apparatus determines resources for communicating retransmission feedback for communications received over the downlink resource assignment based on an index of a resource related to the downlink resource assignment and the offset. The apparatus transmits retransmission feedback for the communications over the resources.

    Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus of a first cell communicates with a second cell in relation to a coordinated multipoint (CoMP) transmission of control information by the second cell and data by the first cell to a user equipment (UE) in a range expanded region of the first cell, determines a desired transmission power level for an uplink transmission to the first cell by the UE, and provides the desired transmission power level for the uplink transmission to the second cell.

    Abstract: Disclosed are techniques for wireless communication. In an aspect, a first network node (e.g., BS, RU, etc.) transmits, to a second network node (e.g., UE, RU, etc.), indicates of precoding matrixes associated with bandwidth region with intervening bandwidth section(s). The second network node generates interpolated precoding matrix(es) associated with the intervening bandwidth section(s) via interpolation. The second network node performs uplink precoding intervening bandwidth section(s) based on the interpolated precoding matrix(es). The first network node receives transmission based on the uplink precoding.

    Abstract: Methods, systems, and devices for wireless communication are described. A wireless communication device may receive control signaling that indicates a change in one or more radio frequency thresholds for wireless signaling. The wireless communication device may perform, as part of an in-band clipping procedure, noise repetition and noise shaping to reduce a peak-to-average power ratio (PAPR) associated with the wireless signaling. The noise repetition and the noise shaping may include generating a set of values with one or more first values and one or more second values. The one or more first values may be associated with an error margin between a sample of a wireless communication signal and a clipping threshold. The one or more second values may be inversions of the one or more first values. The wireless communication device may apply the set of values to the wireless communication signal to reduce PAPR.
