    Abstract: Systems and methods provide solutions for testing an 8Rx capable UE using test cases for 4Rx capable UEs. An example method establishes a connection from a first Tx source and a second Tx source to each of 8Rx antenna ports. The connection duplicates a fading channel from both the first Tx source and the second Tx source to each of the eight Rx antenna ports, and adds independent noise for each of the 8Rx antenna ports. One test scenario uses 4Rx supported RF bands by connecting four of the Rx ports with data from a system simulator, and the other four Rx ports are connected with zero input. Same requirements specified with 4Rx capable UEs are applied. Another test scenario uses 8Rx supported RF bands and applies lower dB SNR requirements than those specified for 4Rx tests.

    Abstract: The position of User Equipment (UE) may be determined based on information communicated through direct UE-to-UE communications to obtain additional measurements of position metrics that can be used to determine relative or absolute positions of the UE. In one implementation, a UE may receive, via a direct connection with a second UE, a positioning reference signal from which timing information, relating to distance between the UE and second UE, is derivable; determine, based on the positioning reference signal, a first position metric that relates to a position of the UE with respect to the second UE; and determine, based at least on position metric, a location of the UE.
