Section: 7.2 Diversity characteristics
Content: The requirements in Section 7 assume that the receiver is equipped with two Rx port as a baseline. These requirements apply to all UE categories unless stated otherwise. Additional requirements apply for UE(s) equipped with four Rx ports. These additional requirements also apply for supported band combinations for which the UE can operate using up to four Rx ports while configured with carrier aggregation. With the exception of subclause 7.9 all requirements shall be verified by using both (all) antenna ports simultaneously. NOTE: for an operating band in which the UE can operate using up to four Rx ports, it suffices to verify for conformance the additional requirements applicable for four Rx ports [except for REFSENS]. NOTE: Implementation of 4 antenna ports for all operating bands supported by the UE is not mandated. For a category 0, a category [M 1] , category 1bis, category NB1 and NB2 UE the requirements in Section 7 assume that the receiver is equipped with single Rx port.
