摘要： The embodiments herein relate to method performed by a measurement device (801, 1000), the method comprising: receiving (901), via higher layer signalling, information on resources or resource sets of one or more transmission devices transmitting one or more beam signals associated with said resources or resource sets; performing (902) channel measurements of the one or more beam signals, per spatial filter of the measurement device; storing (903), over at least one time frame, the channel measurements into measurement groups, where each measurement group corresponds to the channel measurements performed using the same spatial filter of the measurement device; and reporting (904) the measurement groups to a network node (804, 1200) or correlating the measurements with reference data for each available time frame individually and reporting the result of the correlation to the network node (804, 1200). The embodiments also relate to a method performed by a network node (804, 1200).

摘要： The present disclosure relates to methods and apparatuses for improving positioning of a device in a wireless communications network. In some embodiments, a method performed by a measuring device (201, 1300) configured to communicate with a positioning device (205, 1500), comprises: determining (1201) a cross-correlation between a received signal and a transmitted reference signal; determining (1202) a channel impulse response (CIR) of the cross-correlation related to a first lobe detected above a selected threshold in said CIR; and reporting (1203) information on a truncated part of the CIR around the first lobe to the positioning device (205, 1500) for enabling the positioning device (205, 1500) to correct or estimate a measurement related to a distance between a transmitter (202, 203, 204) and the measuring device (201, 1300) and/or a distance between at least one reflecting cluster and the measuring device (201, 1300).

摘要： The embodiments herein relate to method performed by network entity (LMF) and also relate to a location server including the LMF for reducing interference caused to or by positioning signals. The method comprising: acquiring (1501), from a serving network node serving a user equipment, UE, a configuration of an uplink positioning signal and information on uplink resources for the UE to transmit the uplink positioning signal; identifying (1502) at least one network entity, that need to receive the uplink positioning signal from the UE to be positioned; collecting (1503) information about each neighboring cell neighboring at least one network node nearest the at least one network entity; and informing (1504) each network node controlling a neighboring cell to keep certain uplink resources constrained or unscheduled to avoid interference with the uplink resources used by the UE to transmit the uplink positioning signal to said at least one network entity.

摘要： The embodiments herein relate to a method for (RTT), measurement procedure in a communication network, the method comprising: (701) setting a positioning mode; (702) identifying a number of neighboring radio base station, n-gNBs, based on at least one report from a at least one User Equipment, or from UE information based on at least one measurement performed by a serving radio base station, s-gNB, serving said UE; and (703) initiating configuration by:- acquiring capabilities of said at least one UE and capabilities from at said radio base stations, gNBs,- reporting by said at least one UE beam measurements for the n-gNBs from said at least one report; and
setting resources for the s-gNB and the n-gNBs. There is also provided a system and apparatuses in the form of a UE, a gNB and a location server
