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： 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 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.

摘要： Methods and apparatus are provided for operating in a first RAN at a working frequency, determining a priority of measurement tasks enabled by the first RAN, and dynamically scheduling the tasks according to the priority. For certain aspects, the first RAN may be a TD-SCDMA network. The measurement tasks are intended to measure at least one parameter of a serving cell in the first RAN on a primary frequency, at least one cell in the first RAN on at least one frequency other than the primary frequency, one or more cells in at least one RAN other than the first RAN (e.g., a GSM network) or any combination thereof. This dynamic assignment allows the UE to make scheduling decisions on which frequencies and RANs to measure, as well as how often these frequencies and RANs are measured, thereby providing for more efficient use of idle slots over conventional haphazard scheduling.
