36.521-13GPPEvolved Universal Terrestrial Radio Access (E-UTRA)Part 1: Conformance testingRadio transmission and receptionRelease 17TSUser Equipment (UE) conformance specification
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. With the exception of clause 7.9, all requirements shall be verified by using both (all) antenna ports simultaneously.
NOTE 1: 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, which meas for the requirements in Section 7, the UE shall be verified with two Rx antenna ports in operating bands where it is not equipped with four Rx antenna port, and the UE shall be verified with four Rx antenna ports in operating bands where it is equipped with four Rx antenna port.
NOTE 2: Implementation of 4 antenna ports for all operating bands supported by the UE is not mandated.
For a category category 0, a category [M1], category 1bis, NB1 and NB2 UE the requirements in Section 7 assume that the receiver is equipped with single Rx port.
