  • Publication number: 20220095296
    Abstract: The present disclosure relates methods and apparatuses (UE, scheduler, network node) for resource allocation in a network. According to embodiments herein there are provided a new resource allocation scheme for an UL-TDOA resource allocation scheme and the related UL-PRS signals. The procedure is also applicable for RTT uplink resource allocation. The main technical effects and advantages achieved by the embodiments herein include: A resource allocation concept offering a high flexibility. The positioning update rate is configurable for each UE allowing that for semi static objects a low update rate is selected whereas for moving devices a high update rate is feasible. The signalisation overhead is minimized. The UEs may be configured semi-persistent. Using different transmit periods for each UE results in random SINR (Signal to Interference Noise Ratio) values and ensures that UEs with high pathloss are also detected.

    Abstract: A receiver, which is located in a spatial region of interest served by a transmitter of a wireless communication network, receives a radio signal from at least one transmitter of the wireless communication network, and the radio signal has a plurality of position reference signal (PRS) sequences. Each PRS sequence has associated therewith a different PRS sequence identifier, and each PRS sequence is send using a different beam cone of the transmitter. The beam cones of the transmitter for sending the plurality of PRS sequences are directed to the spatial region of interest. The receiver processes the radio signal to estimate a time of arrival of each PRS sequence and to obtain for each PRS sequence the associated PRS sequence identifier. A position of the receiver is estimated using the times of arrival and the obtained PRS sequence identifiers.
