摘要： Systems and methodologies are described herein that facilitate reduced complexity network-assisted device positioning in a wireless communication system. As described herein, a mobile device and/or other suitable device can utilize positioning assistance messages received from a location server, a serving network cell, and/or other entities, to assist in position fixing based on reference signals (e.g., positioning reference signals (PRSs)) detected from nearby network cells. Positioning assistance messages as described herein can include, for example, information relating to PRS bandwidths, transmit antenna configurations, and/or other parameters of respective cells from which reference signals are detected by a device during positioning. As further described herein, messaging load can be reduced by providing bandwidth and/or antenna configuration information relative to a given reference cell, such that parameters of non-reference cells that are equivalent to corresponding parameters of the reference cell can be omitted from transmitted positioning assistance data.

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 subframes. Resource elements within the positioning subframe 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, portions of a subframe not designated for PRS transmission can be utilized for user plane data transmission.

摘要： Chase combining gains for receiving a scrambled broadcast channel can be achieved even when a portion of each received channel coded transmission contains a portion that varies. A set of possible difference values for this varying portion, such as for a system frame number, provides hypotheses, each having a corresponding probability. One or more of the hypotheses are selected by rank order for adjusting a corresponding received coded transmission so that two or more channel coded transmissions can be combined and blind decoded until one of the hypotheses are confirmed.

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 methods are described to supply positioning reference signal (PRS) in a telecommunication system. A base station supplies a PRS sequence according at least to a time-frequency pattern of modulation symbols, wherein the time-frequency pattern assigns a modulation symbol to each frequency tone in a block of time-frequency resources allocated to transmit PRS. The base station associates a modulation symbol in the time-frequency pattern with a reference symbol in the PRS sequence through a mapping that represents the time-frequency pattern. The PRS sequence is conveyed to user equipment through delivery of a set of modulation symbols established through the mapping. Different time-frequency patterns can be exploited based on time-structure of a radio sub-frame. The user equipment receives the PRS sequence according to at least the time-frequency pattern of modulation symbols and utilizes at least the PRS sequence as part of a process to produce a location estimate.
