    摘要： 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. The sequences used for positioning are optimized according to the ToA measurement requirements (unlike the existing SRS).

    摘要： The invention concerns a method for receiving and a receiver configured to receive a radio signal (100) carrying information, the radio signal (100) comprising an overall frequency band (f overall ) having a first frequency sub band (101) and a second frequency sub band (102). According to the invention, the receiver is further configured to receive during a first time period (T 1 ) a first portion (111) of the information carried by the radio signal in the first frequency sub band (101), and to receive during a second time period (T 2 ) a second portion (112) of the information carried by the radio signal in the second frequency sub band (102). The receiver is further configured to perform a channel estimation (121) of the first frequency sub band (101) in orderto determine a first phase (131) and to perform a channel estimation (122) of the second frequency sub band (102) in order to determine a second phase (132). According to the invention, the receiver is further configured to determine an overall phase basis (133) of the radio signal using the first and second phases (131, 132).

    摘要： A receiver (UE), which is located in a spatial region of interest (118) served by a transmitter (eNB 1 -eNB 3 ) of a wireless communication network, receives a radio signal from at least one transmitter (eNB 1 -eNB 3 ) 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 (116) of the transmitter (eNB 1 -eNB 3 ). The beam cones (116) of the transmitter (eNB 1 -eNB 3 ) for sending the plurality of PRS sequences are directed to the spatial region of interest (118). The receiver (UE) processes the radio signal to estimate a time of arrival (TOA) of each PRS sequence and to obtain for each PRS sequence the associated PRS sequence identifier. A position of the receiver (UE) is estimated using the times of arrival and the obtained PRS sequence identifiers.
