Abstract: Embodiments of the present disclosure provide apparatus, methods and computer readable storage mediums for configuring resources for positioning reference signals. In one aspect, the apparatus determines a second set of resource configuration for positioning reference signal (PRS) mapping to resource elements in the second set, which is an extension of the first set of resource configuration for PRS mapping with additional resource elements. In another aspect, another apparatus determines configurations of at least one of the first set and the second set, to configure PRS transmission according to the first set or the second set.

Abstract: In accordance with example embodiments of the invention there is at least a method, device, and computer readable medium for determining a Timing Advance. A method includes, the network device determines an estimation of a timing advance and an error of the timing advance based on a random access preamble received from the terminal device, the network device determines different communication modes with different lengths of overheads for the terminal device based on the error, and the network device can update the estimation of the timing advance based on feedback information from the terminal device. In this way, accuracy of the estimation of the timing advancing is improved.

Abstract: Methods and apparatus for transmitting positioning measurement report are provided. The method includes a step of receiving a location information request from a serving base station or from a location server, a step of determining timing for transmitting a positioning measurement report, a step of generating a report assisted message based on the determined timing for transmitting the positioning measurement report, and a step of transmitting the report assisted message to the serving base station. The key idea of this disclosure is requesting UL resources for positioning measurement report in advance by transmitting a report assisted message. Consequently, the UE can transmit the positioning measurement report just after the measurement data being generated. The disclosure can minimize the delay from positioning measurement data generation to the positioning measurement report.
