    Abstract: When enabled with common reference signal interference cancelation, a user equipment (UE) may still compute a channel state feedback value with consideration of any canceled interfering neighboring signals. When the neighboring cells are determined to be transmitting data during the time for which the channel state feedback value is being computed, the UE is able to derive the channel state feedback value considering those canceled interfering signals. The UE determines whether each neighboring cell is transmitting during the designated time either by obtaining signals that indicate the transmission schedule of the neighboring cells or by detecting the transmission schedule, such as based on the power class of the neighboring cells. If the UE determines that the neighboring cells are transmitting data during this time period, the UE will compute the channel state feedback value including consideration of the canceled interfering signals.

    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的SPS许可可能需要改变,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: An method of wireless communication dynamically indicates traffic to pilot ratio (T/P) values in heterogeneous networks. Subframes are categorized into groups that do not overlap. A traffic to pilot ratio (T/P) indicator is received and the a T/P value for a group of subframes is determined based at least in part on the received T/P indicator.

    Abstract: Certain aspects of the present disclosure provide methods and apparatus for employing relaying devices, such as Long Term Evolution (LTE) user equipment (UE) relays, having a licensed wireless or wired backhaul link and an unlicensed access link. One method generally includes receiving, at a first device, data from a first apparatus via a first carrier frequency in a licensed spectrum, wherein the first device comprises a relaying device, and relaying the data to a second apparatus via a second carrier frequency in an unlicensed spectrum. In this manner, wireless communication systems with relaying devices may achieve better spectral efficiency in unlicensed access links.

    Abstract: Methods, systems, and devices for wireless communications are described in which wireless nodes may use licensed shared radio frequency spectrum band for communications and one or more neighboring networks may use a same licensed shared radio frequency spectrum band. A second network of the one or more neighboring networks may have priority of use of the licensed shared radio frequency spectrum band within a particular geographic area. Disclosed techniques provide that nodes of each network may indicate an identification of the network, a network priority, or both, in over-the-air signaling. Wireless nodes may determine if another neighboring network is present based on the over-the-air signaling, may determine whether the other network has a higher priority, and may adjust one or more transmissions in the event that a higher priority network is identified, such as through reducing transmission power.

    Abstract: Methods, systems, and devices for wireless communications are described for communications between a user equipment (UE) and a base station via one or more relays. The UE and base station may establish a direct connection according to a first UE capability, and the UE may identify one or more relays that are in proximity to the UE and that may be used for relaying communications between the UE and the base station. The UE may provide a capability indication of a second UE capability to the base station that indicates transmission parameters associated with at least one relay, which the base station may use to communicate with the UE via the relay. The base station may select which UE capability to use for communications, which may result in either direct communications with the UE or a connection via the relay.
