METHODS AND APPARATUSES FOR FINGERPRINTING EMPLOYING FUNCTION-BASED MATCHING PATTERNS

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).
