摘要： The present invention relates to a method for a network entity, NE, to optimize positioning of a user equipment, UE, (UE4) where the reliability of the positioning of a UE (UE4) depend on static circumstances and situational/environmental circumstances. Static circumstances are the sensor capabilities and sensor quality related to the UE (UE4) and general system limitations, and they remain the same regardless of the position (p1, p2, p3, ..., p6) of the UE (UE4). Situational or environmental circumstances depend on the situation or environment of the UE, and they change with the position (p1, p2, p3, ..., p6) and/or other physical states of the UE (UE4). The invention teaches that the NE request a quality report from a measurement unit, MU, to enable the MU to report on quality changes due to situational or environmental circumstances to the NE in order to enable the NE to decide on the best positioning method for the UE (UE4) in the current situation.

摘要： A method for operating a wireless communication network that supports a plurality of reference signals such as sounding reference signals as provided. The method comprises analyzing a channel condition between a UE and TRPs, providing a measurement report to the wireless communication network and determining parameters of an uplink RS based on the measurement report. The method further comprises receiving, with the user equipment, at least one instruction signal comprising information indicating the determined parameters of the uplink RS, and transmitting the uplink RS within the UE so as to allow determining uplink transmission links for a UE multi-TRP communication or a position of the UE in the wireless communication network based on an evaluation of transmittal of the instructed uplink RS.

摘要： An apparatus for a wireless communication system is described. The apparatus is to transmit a reference signal on a common set of resource elements, REs, the common set of REs used by one or more further apparatuses in the wireless communication system to transmit the reference signal so that the reference signals of the apparatus and of the one or more further apparatuses use the same REs. The apparatus is to transmit the reference signal using a plurality of OFDM symbols, each OFDM symbol having a comb structure, and some or all of the OFDM symbols having different comb offsets, and apply the same sequence to each OFDM symbol, the sequence having a zero auto correlation property, the apparatus and the one or more further apparatus using for a common RE the same sequence. The apparatus is to apply a phase correction to an OFDM symbol before transmission, wherein the phase correction is applied in the time domain or in the frequency domain by multiplying the ODFM symbol with a correction factor e jϕc , and wherein the correction factor e jϕc depends on the comb factor and the comb offset of the OFDM symbol and is independent of the resource element.

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).
