摘要： Systems and methodologies are described that facilitate providing high reuse for transmitting reference signals, such as positioning reference signals (PRS) and cell- specific reference signals (CRS), to improve hearability thereof for applications such as trilateration and/or the like. In particular, PRSs can be transmitted in designated or selected positioning sub frames. Resource elements within the positioning sub frame can be selected for transmitting the PRSs and can avoid conflict with designated control regions, resource elements used for transmitting cell-specific reference signals, and/or the like. Resource elements for transmitting PRSs can be selected according to a planned or pseudo-random reuse scheme. In addition, a transmit diversity scheme can be applied to the PRSs to minimize impact of introducing the PRSs to legacy devices. Moreover, potions of a subframe not designated for PRS transmission can be utilized for user plane data transmission.
摘要翻译：描述了便于提供用于传输参考信号（诸如定位参考信号（PRS）和小区特定参考信号（CRS））的高重用以提高其对诸如三边测量等应用的可用性的系统和方法。具体而言，PRS可以在指定或选定的定位子帧中传输。定位子帧内的资源元素可以被选择用于发送PRS，并且可以避免与指定的控制区域，用于发送小区特定的参考信号的资源元素等的冲突。用于传输PRS的资源元素可以根据计划或伪随机重用方案来选择。另外，可以将发射分集方案应用于PRS以最小化将PRS引入到传统设备的影响。而且，未被指定用于PRS传输的子帧部分可以用于用户平面数据传输。

摘要： Systems and methodologies are described that facilitate transmitting positioning reference signals (PRS) differently for passive distributed elements. PRSs for passive distributed elements can be transmitted over disparate resources than those utilized for PRSs at a related access point, using different symbol sequences, and/or the like. In this regard, wireless devices can differentiate between PRSs from access points and those from passive distributed elements, which can mitigate confusion for processes involving such RSs, such as position determining. Alternatively, passive distributed elements can refrain from transmitting PRSs, and a corresponding access point can indicate to wireless devices to only determine positioning based on PRSs. Thus, the wireless devices can utilize the PRSs transmitted from the access point (and not other reference signals transmitted from the passive distributed element) to determine a position.
摘要翻译：描述了有助于以无源分布式元件不同地传送定位参考信号（PRS）的系统和方法。用于被动分布式元件的PRS可以在不同资源上传输，而不是使用不同的符号序列等在相关接入点用于PRS的资源。在这方面，无线设备可以区分来自接入点的PRS和来自被动分布元件的PRS，其可以减轻涉及这种RS的过程的混淆，诸如位置确定。或者，被动分布式元件可以避免传输PRS，相应的接入点可以向无线设备指示仅基于PRS确定定位。因此，无线设备可以利用从接入点发送的PRS（而不是从被动分布式元件发送的其他参考信号）来确定位置。

摘要： Systems and methodologies are described that facilitate commanding a wireless device to transmit a random access channel (RACH) signal to measure communication parameters related thereto. The wireless device can transmit a RACH preamble upon receiving a command, and one or more parameters can be computed based at least in part on transmitting the command and/or receiving the RACH preamble, such as a round trip time, a received signal power, and/or the like. The one or more parameters can be communicated to the wireless device in a RACH response signal, and can be utilized by the wireless device. The wireless device can utilize the one or more parameters to estimate a distance for position determination, compute a path loss, and/or the like.

摘要： A method, apparatus are described for a cloud based radio access network (RAN). The method may include transmitting a first message from a base station to a user equipment (UE), determining that a second message from the UE is not received by a media access control (MAC) scheduler within a pre-determined time, delaying re-transmission of the first message or transmission of a third message from the base station to the UE, and scheduling other hybrid automatic repeat request (HARQ) processes of the UE in intervening sub-frames. The method may include receiving a first message from a UE at a base station, determining that a second message from the base station cannot be constructed within a pre-determined time from delays in receiving assignments from a Cloud, constructing and transmitting the second message to UEs based on assignments received earlier from the Cloud, and suspending an HARQ process associated with other UEs.
摘要翻译：描述了一种用于基于云的无线电接入网络（RAN）的方法，装置。该方法可以包括从基站向用户设备（UE）发送第一消息，确定来自UE的第二消息在预定时间内不被媒体接入控制（MAC）调度器接收，传输第一消息或从基站向UE发送第三消息，并且调度UE在中间子帧中的其他混合自动重传请求（HARQ）处理。该方法可以包括在基站处从UE接收第一消息，确定来自基站的第二消息不能在从云接收分配的延迟的预定时间内构建，构造和发送第二消息到基于先前从云接收的分配的用户，并且暂停与其他UE相关联的HARQ过程。
