摘要： An apparatus and method are disclosed for enhancing connection mobility control for small cell networks that may include receiving location information of a wireless transmit/receive unit WTRU. In some embodiments, the method may include determining the location information of the WTRU. The method may include determining a target cell area TCA for the WTRU based on the location information of the WTRU. The TCA comprises one or more target cells. The method may further include transmitting at least one target cell to the WTRU. A method on a WTRU may include receiving a target cell area TCA from a base station. The TCA may include one or more target cells. The method may include responding to a radio link failure (RLF) or handover failure by selecting a target cell from the TCA, and transmitting a connection reestablishment request to the selected target cell. ADDITIONAL DETAILS: The serving BTS calculates a candidate target cell list (TCA, essentially the NCL or a subset thereof) based on a multitude of criteria such as street topology, history of past HO-failures or RLF or UE's speed, location, predicted trajectory or explicit trajectory communicated by the UE to the BTS and transmits it (reference sign 740) to the BTS's of the TCA, together with the UE's context, through the X2 interface (thus, preparing them for HO). The BTS's are prioritized according to the probability of HO occurrence. On HO failure (e. g., T304 timeout), the UE sends a second RACH to the next target cell candidate, which may be prepared or unprepared. If an unprepared cell receives a RACH from the UE, it sends a reset handover to the served cell (paragraph 149).
摘要翻译：公开了一种用于增强小型小区网络的连接移动性控制的装置和方法，其可以包括接收无线发射/接收单元WTRU的位置信息。在一些实施例中，该方法可以包括确定WTRU的位置信息。该方法可以包括基于WTRU的位置信息确定WTRU的目标小区区域TCA。 TCA包含一个或多个靶细胞。该方法还可以包括将至少一个目标小区发送到WTRU。 WTRU上的方法可以包括从基站接收目标小区区域TCA。 TCA可以包括一个或多个靶细胞。该方法可以包括通过从TCA中选择目标小区来响应无线链路故障（RLF）或切换失败，以及向所选择的目标小区发送连接重建请求。附加细节：服务BTS基于诸如街道拓扑，过去HO故障或RLF的历史或UE的速度，位置，预测轨迹等多种标准来计算候选目标小区列表（TCA，本质上是NCL或其子集）或显式轨迹，由UE传送到BTS，并通过X2接口（因此为HO准备）将其（参考符号740）与UE的上下文一起发送到TCA的BTS。根据HO发生的概率优先考虑BTS。在HO故障（例如，T304超时）时，UE向下一个可能准备或未准备的目标小区候选者发送第二RACH。如果未准备的小区从UE接收到RACH，则向服务小区发送重置切换（第149段）。

摘要： A method and apparatus for coexistence among wireless transmit/receive units (WTRUs) operating in the same spectrum are disclosed. A WTRU includes a memory, a receive unit, a transmit unit and a control unit. The memory stores coexistence gap patterns. Each of the coexistence gap patterns defines a pattern of transmission periods and silent periods for the WTRU and corresponds to a respective duty cycle. The receive unit receives from a base station information regarding a duty cycle for a wireless cell operated by the base station. The control unit selects one of the coexistence gap patterns based on the received information regarding the duty cycle for the wireless cell and controls the transmit unit to transmit information during the transmission periods and not transmit information during the silent periods of the selected one of the plurality of coexistence gap patterns.

摘要： A method and apparatus for operating supplementary cells in licensed exempt (LE) spectrum. An aggregating cell operating in a frequency division duplex (FDD) licensed spectrum is aggregated with a LE supplementary cell operating in a time sharing mode for uplink (UL) and downlink (DL) operations. The LE supplementary cell may be an FDD supplementary cell dynamically configurable between an UL only mode, a DL only mode, and a shared mode, to match requested UL and DL traffic ratios. The LE supplementary cell may be a time division duplex (TDD) supplementary cell. The TDD supplementary cell may be dynamically configurable between multiple TDD configurations. A coexistence capability for coordinating operations between the LE supplementary cell with other systems operating in the same channel is provided. Coexistence gaps are provided to measure primary/secondary user usage and permit other systems operating in the LE supplementary cell channel to access the channel.
