7 Conducted receiver characteristics
38.101-53GPPNRPart 5: Satellite access Radio Frequency (RF) and performance requirementsRelease 17TSUser Equipment (UE) radio transmission and reception
7.1 General
Unless otherwise stated the receiver characteristics are specified at the antenna connector(s) of the UE. For UE(s) with an integral antenna only, a reference antenna(s) with a gain of 0 dBi is assumed for each antenna port(s). UE with an integral antenna(s) may be taken into account by converting these power levels into field strength requirements, assuming a 0 dBi gain antenna. For UEs with more than one receiver antenna connector, identical interfering signals shall be applied to each receiver antenna port if more than one of these is used (diversity).
The levels of the test signal applied to each of the antenna connectors shall be as defined in the respective clauses below.
With the exception of clause 7.3, the requirements shall be verified with the network signalling value NS_01 configured in Table 6.2.3.1-1.
All the parameters in clause 7 are defined using the UL reference measurement channels specified in 3GPP TS 38.101-1 [5] Annex A.2.2, the DL reference measurement channels specified in 3GPP TS 38.101-1 [5] Annex A.3.2 and using the set-up specified in 3GPP TS 38.101-1 [5] Annex C.3.1.
7.2 Diversity characteristics
The UE is required to be equipped with a minimum of two RX antenna ports in all operating bands.
The UE shall be verified with two RX antenna ports in all supported frequency bands.
The above rules apply for all clauses with the exception of clause 7.9.
7.3 Reference sensitivity
7.3.1 General
The reference sensitivity power level REFSENS is the minimum mean power applied to each one of the UE antenna ports for all UE categories, at which the throughput shall meet or exceed the requirements for the specified reference measurement channel.
In later clauses of Clause 7 where the value of REFSENS is used as a reference to set the corresponding requirement:
in all bands, the UE shall be verified against those requirements by applying the REFSENS value in Table 7.3.2-1.
7.3.2 Reference sensitivity power level
The throughput shall be ≥ 95 % of the maximum throughput of the reference measurement channels as specified in Annex A3.2.2 of 3GPP TS 38.101-1 [5], with parameters specified in Table 7.3.2-1.

7.5 Adjacent channel selectivity
Adjacent channel selectivity (ACS) is a measure of a receiver’s ability to receive an NR signal at its assigned channel frequency in the presence of an adjacent channel signal at a given frequency offset from the centre frequency of the assigned channel. ACS is the ratio of the receive filter attenuation on the assigned channel frequency to the receive filter attenuation on the adjacent channel(s).
In Release 17, only frequency bands below 2.7GHz are considered. The NR satellite UE shall fulfil the minimum requirements specified in Table 7.5-1 for NR satellite bands with FDL_high < 2700 MHz and FUL_high < 2700 MHz. These requirements apply for all values of an adjacent channel interferer in case 1 and for any SCS specified for the channel bandwidth of the wanted signal. The lower and upper range of test parameters are chosen as in Table 7.5-2 and Table 7.5-3 for verification of the requirements specified in Table 7.5-1. For these test parameters, the throughput shall be ≥ 95 % of the maximum throughput of the reference measurement channels as specified in 3GPP TS 38.101-1 [5] Annexes A.2.2, A.3.2, and A.3.3 (with one sided dynamic OCNG Pattern OP.1 FDD/TDD for the DL-signal as described in 3GPP TS 38.101-1 [5] Annex A.5.1.1/A.5.2.1).

7.6 Blocking characteristics
7.6.1 General
The blocking characteristic is a measure of the receiver’s ability to receive a wanted signal at its assigned channel frequency in the presence of an unwanted interferer on frequencies other than those of the spurious response or the adjacent channels, without this unwanted input signal causing a degradation of the performance of the receiver beyond a specified limit. The blocking performance shall apply at all frequencies except those at which a spurious response occurs.
7.6.2 In-band blocking
For NR satellite bands with FDL_high < 2700 MHz and FUL_high < 2700 MHz in-band blocking (IBB) is defined for an unwanted interfering signal falling into the UE receive band or into the first 15 MHz below or above the UE receive band.
The throughput of the wanted signal shall be ≥ 95 % of the maximum throughput of the reference measurement channels as specified in 3GPP TS 38.101-1 [5] Annexes A.2.2, A.3.2 and A.3.3 (with one sided dynamic OCNG Pattern OP.1 FDD/TDD for the DL-signal as described in Annex A.5.1.1/A.5.2.1) with parameters specified in Table 7.6.2-1 and Table 7.6.2-2. The relative throughput requirement shall be met for any SCS specified for the channel bandwidth of the wanted signal.

7.6.3 Out-of-band blocking
For NR satellite bands with FDL_high < 2700 MHz and FUL_high < 2700 MHz out-of-band band blocking is defined for an unwanted CW interfering signal falling outside a frequency range 15 MHz below or above the UE receive band.
