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： Aspects are disclosed for sequencing and correlating a positioning reference signal. A set of reference symbols associated with a reference signal are allocated, and a base sequence is generated. An extended sequence, which includes the set of reference symbols, is then provided according to the base sequence. The extended sequence is then transmitted in a sub-frame designated as an idle period. A sequence of reference symbols is received from a base station during an idle period of the base station. A replicated sequence of reference symbols is generated, and a correlation is ascertained between a subset of the received sequence of reference symbols and a corresponding subset of the replicated sequence of reference symbols. The received sequence of reference symbols is then identified according to the correlation.

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： 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： 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.
