    Abstract: A femto base station (BS) maintains two different timings: a femto BS downlink timing and a femto BS uplink timing. A femto base station's uplink reference timing is based on the macro uplink timing being used by one or more UE devices in the local vicinity of the femto BS. In some embodiments, the femto BS synchronizes its femto uplink timing to the macro uplink timing being used by the closest UE device transmitting uplink signals to the macro BS. In other embodiments, the femto BS determines its femto base station uplink timing based on one or more uplink signals from UE devices in its vicinity transmitting to the macro BS. In various embodiments, femto cell uplink signals and macro cell uplink signals are received at a femto cell BS in synchronization. This approach facilitates frequency division multiplexing (FDM) in the uplink between a macro cell and a femto cell.

    Abstract translation: 毫微微基站（BS）维护两个不同的定时：毫微微BS下行链路定时和毫微微BS上行链路定时。 毫微微基站的上行链路参考定时是基于在毫微微BS的本地附近的一个或多个UE设备使用的宏上行链路定时。 在一些实施例中，毫微微BS将其毫微微上行链路定时与最近的UE设备使用的宏上行链路定时进行同步，从而向宏BS发送上行链路信号。 在其他实施例中，毫微微BS基于从其附近的UE设备发送到宏BS的一个或多个上行链路信号来确定其毫微微基站上行链路定时。 在各种实施例中，在毫微微小区BS同步地接收毫微微小区上行链路信号和宏小区上行链路信号。 这种方法有助于在宏小区和毫微微小区之间的上行链路中的频分复用（FDM）。

    Abstract: Methods and apparatus that facilitate handover related measurements and decision making in a communications system including user equipment (UE) devices, a macro base station and femto base stations (femtocells) are described. In some embodiments a UE device transmits pilots along with identification information using UE device selected transmission resources from a set of recurring UE pilot transmission resources dedicated by a macro base station for UE pilot signal and related device information transmission purposes. Femto base stations measure the UE transmitted pilot signals and report the signal strength measurement results and corresponding device identifiers to a handoff decision control entity, e.g., an eNodeB or control node, which makes handover decisions. By relying on UE transmitted pilots measured by multiple base stations, e.g., femto base stations, the need for femto cells to transmit pilots can be reduced while well informed UE handoff decisions still being possible.

    Abstract translation: 描述了在包括用户设备（UE）设备，宏基站和毫微微基站（毫微微小区）的通信系统中促进切换相关测量和决策的方法和装置。 在一些实施例中，UE设备使用UE设备选择的传输资源从用于UE导频信号的宏基站专用的一组循环UE导频传输资源和相关设备信息传输目的来发送导频。 毫微微基站测量UE发送的导频信号，并将信号强度测量结果和相应的设备标识符报告给切换决策控制实体，例如进行切换决定的eNodeB或控制节点。 通过依赖由多个基站（例如，毫微微基站）测量的UE发射的导频，可以减少对毫微微小区发送导频的需要，同时可以很好地告知UE切换决定仍然是可能的。

    Abstract: A configuration to allow for the suppression or delay of the changing of an ID of a first wireless device to maintain a connection with another wireless device. The apparatus establishes a connection with a second wireless device using a side link. An ID of a first wireless device is provided to the second wireless device. The apparatus determines to change the ID of the first wireless device based on a predetermined schedule. The apparatus initiates a suppression to change of the ID of the first wireless device to maintain the connection with the second wireless device.

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured for contention-based forwarding (CBF) to relay a message toward a destination. The UE may receive signaling indicating a configuration for CBF. The CBF configuration may be associated with a maximum communication range for CBF signaling. The UE may receive a message to relay toward the destination using CBF. The message may include a first indication of a dynamic communication range for the CBF which may be less than or equal to the maximum communication range. The UE may determine a timer value to retransmit the message based on the dynamic communication range. When a timer set to the timer value expires, the UE may retransmit the message to nearby stations and include an indication of the dynamic communication range with the message.

    Abstract: A user equipment (UE) may experience poor communication with a network access device, and the network access device may configure the UE to connect to, and route communications through, one or more relay nodes (e.g., which may be another UE, a network operator-deployed relay, etc.). Techniques are described whereby these relay nodes may autonomously form a wireless backhaul network. Sequential implementations are considered such that the size of the wireless backhaul network may scale efficiently. In some examples, the wireless backhaul network may form by reusing existing connectivity establishment procedures. Importantly, the proposed techniques enable a relay to possess (e.g., be configured with) functionality that may traditionally be associated with a UE, base station, and gateway. Such multi-faceted functionality may enable the described sequential formation of wireless backhaul networks with tree topology.
