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.
