8.1 General

36.1043GPPBase Station (BS) radio transmission and receptionEvolved Universal Terrestrial Radio Access (E-UTRA)Release 18TS

Performance requirements for the BS are specified for the fixed reference channels defined in Annex A and the propagation conditions in Annex B. The requirements only apply to those FRCs that are supported by the base station.

Unless stated otherwise, performance requirements apply for a single carrier only. Performance requirements for a BS supporting carrier aggregation are defined in terms of single carrier requirements. For FDD operation the requirements in clause 8 shall be met with the transmitter(s) on.

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].

The SNR used in this clause is specified based on a single carrier and defined as:

SNR = S / N

Where:

S is the total signal energy in the subframe on a single antenna port.

N is the noise energy in a bandwidth corresponding to the transmission bandwidth over the duration of a subframe.

For enhanced performance requirements type A and type B, the SINR used in this clause is specified based on a single carrier and defined as:

Where:

is the total signal energy of one intra-cell UE in the subframe on a single antenna port.

is the summation of the received energy of the strongest inter-cell interferers explicitly defined in a test procedure plus the white noise energy N, in a bandwidth corresponding to the transmission bandwidth over the duration of a subframe on a single antenna port. The respective energy of each inter-cell interferer relative to is defined by its associated DIP value.
