Abstract: A method of providing location option control for Minimization of Drive Test (MDT) in LTE systems is provided. In one embodiment, a UE or an eNB receives an MDT location request that comprises an MDT location option configuration having one or more location options. The UE or eNB determines a first location option based on the MDT location option configuration and initiates positioning for MDT measurements, reporting, and logging according to the first location option. In one novel aspect, each location option is associated with a priority. In addition to MDT measurements, reporting, and logging, a UE determines the best positioning procedure from a list of available location options. In one novel aspect, under a specific positioning objective, the UE prioritizes the list of available location options based on the signal strength and/or quality of cellular and WLAN signals.

Abstract: A communications apparatus is disclosed. A receiving module receives an observed time difference of arrival (OTDOA) request and a search list of cells provided by a network at a second time point. A comparing module compares the received search list to a stored search list of cells which is received at a first time point and stored in a database. A searching module searches at least one of the cells from the received search list by using different search ranges adjusted according to the comparison result, and stores the at least one of the cells in the database. A measuring module performs OTDOA measurements by detecting positioning reference signals (PRS) from the at least one of the cells.

Abstract: A wireless device includes a satellite receiver to receive data from multiple satellites. The wireless device also includes processing circuitry and memory. The memory stores one or more neural network models. The processing circuitry is operative to identify a neural network model that has been trained to adapt to a region in which the wireless device operates, classify satellite raw measurements from each satellite at a given time into a corresponding quality level using the neural network model, and identify satellite raw measurements with a quality level higher than a threshold. The location of the wireless device is calculated using the identified satellite raw measurements.
