    Abstract: Time division multiplexing (TDM) partitioning is one of the inter-cell interference coordination (ICIC) mechanisms considered for a heterogeneous network (HetNet) ICIC in a co-channel deployment. For example, in subframes that are pre-allocated to an evolved Node B (eNB), neighbor eNBs may not transmit, hence interference experienced by served user equipments (UEs) may be reduced. Semi-persistent scheduling (SPS) grants may have various available periodicities, which may not be compatible with TDM partitioning. Therefore, a UE may miss an SPS opportunity that was scheduled for a subframe that was not usable by the UE. Hence, using SPS grants with small periodicities in a heterogeneous network with TDM partitioning may require changes which may include adjusting the periodicities of the SPS grants, rescheduling of uplink SPS messages based on resource partitioning information (RPI), and/or determining RPI based on current SPS grants.

    Abstract translation: 时分复用（TDM）分区是在同频道部署中为异构网络（HetNet）ICIC考虑的小区间干扰协调（ICIC）机制之一。 例如，在预分配给演进节点B（eNB）的子帧中，相邻eNB可能不发送，因此可能减少被服务用户设备（UE）经历的干扰。 半静态调度（SPS）授权可能具有各种可用的周期性，这可能与TDM分区不兼容。 因此，UE可能错过针对UE不可用的子帧调度的SPS机会。 因此，在具有TDM分割的异构网络中使用具有小周期性的SPS授权可能需要改变，其可以包括调整SPS授权的周期性，基于资源划分信息（RPI）重新安排上行SPS消息，和/或基于 当前SPS赠款。

    Abstract: Techniques are provided for combining different types of reference signals. A wireless communications network may be configured to allow a user equipment (UE) to combine multiple demodulation reference signals (DM-RSs) to support demodulation of a physical downlink shared channel (PDSCH), and/or other downlink transmissions, transmitted from a base station to the UE. The base station may provide explicit signaling that reference signals transmitted in two or more transmission time intervals may be combined, or a determination that reference signals transmitted in two or more transmission time intervals may be combined may be made implicitly based on system configuration and previous transmissions. Based on the explicit signaling and/or implicit determination, a UE may combine reference signals included in each of two or more reference signals for use in demodulation of downlink transmissions.

    Abstract: Techniques are described for wireless communication. A first method includes receiving a primary synchronization signal (PSS) from a base station over an unlicensed radio frequency spectrum band. The PSS may be received on adjacent orthogonal frequency division multiplexing (OFDM) symbols of a first subframe of a downlink transmission. A user equipment (UE) may be synchronized with the base station based at least in part on the received PSS. A second method includes receiving a channel usage indicator over an unlicensed radio frequency spectrum band, and determining at least one OFDM symbol to monitor based on a time associated with the received channel usage indicator. A PSS may then be received from a base station over the unlicensed radio frequency spectrum band during the determined at least one OFDM symbol, and a UE may be synchronized with the base station based at least in part on the received PSS.

    Abstract: Techniques are described for wireless communication. A first method may include transmitting a reference signal from an access point over a shared spectrum to a user equipment (UE), and receiving a measurement of the reference signal from the UE. A second method may include receiving at a UE over a shared spectrum a reference signal from an access point, and transmitting a measurement of the reference signal to the access point. In each of the first and second methods, the measurement may indicate interference with the shared spectrum from outside of a clear channel assessment (CCA) range of the access point. A third method may include receiving a plurality of reference signal measurements, where each reference signal measurement corresponds to one of a plurality of access points and indicates interference with a shared spectrum from outside of a CCA range of the corresponding access point, and performing channel selection for the plurality of access points based at least in part on the received reference signal measurements.

    Abstract: An enhanced acknowledgement indicator channel is discussed that multiplexes acknowledgement signals for multiple uplink signals from various user equipments (UEs) into the enhanced acknowledgement indicator channel. The channel is divided into a number of paired data and pilot resource element groups that can be precoded independently of one another, such that each paired resource element group is precoded using a different or independent precoding than the other paired resource element groups. If the base station determines a failure to decode any uplink signals, instead of sending acknowledgement signals over the indicator channel, the base station may, instead, generate uplink grants for retransmission of the uplink signals.
