The requirements in clause 7 are expressed for a single receiver antenna connector. For receivers with antenna diversity, the requirements apply for each receiver antenna connector.

Unless otherwise stated, the receiver characteristics are specified at the BS antenna connector (test port A) with a full complement of transceivers for the configuration in normal operating conditions. For FDD operation the requirements in clause 7 shall be met with the transmitter(s) on. If any external apparatus such as a RX amplifier, a filter or the combination of such devices is used, requirements apply at the far end antenna connector (port B).

NOTE: In normal operating conditions the BS in FDD operation is configured to transmit and receive at the same time. The transmitter may be off for some of the tests as specifed in 36.141 [4].

Unless otherwise stated the requirements in clause 7 apply during the base station receive period.

The throughput requirements defined for the receiver characteristics in this clause do not assume HARQ retransmissions.

When the BS is configured to receive multiple carriers, all the throughput requirements are applicable for each received carrier. For ACS, blocking and intermodulation characteristics, the negative offsets of the interfering signal apply relative to the lower Base Station RF Bandwidth edge and positive offsets of the interfering signal apply relative to the upper Base Station RF Bandwidth edge.

NOTE: Requirements may only be supported for certain frequency ranges within the operating band(s). These frequency ranges could be different for NB.-IoT comparing to E-UTRA.

NOTE: For E-UTRA BS with NB-IoT (in band and/or guard band) or standalone NB-IoT BS, requirements are defined for 15 kHz sub-carrier spacing and 3.75 kHz sub-carrier spacing. A NB-IoT Base Station supports 15 kHz sub-carrier spacing, 3.75 kHz sub-carrier spacing, or both.
