    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: Systems and methods provide solutions for delay and interruption requirements for vehicle-to-everything (V2X) sidelink carrier aggregation (CA). For example, when any number of component carriers is added for V2X CA, a user equipment (UE) capable of V2X sidelink communication is allowed an interruption of up to two subframes to the cellular network. The interruption may be for both uplink and downlink of a serving cell or primary cell.
