7.3A Reference sensitivity for CA without EN-DC
38.521-33GPPNRPart 3: Range 1 and Range 2 Interworking operation with other radiosRadio transmission and receptionRelease 17TSUser Equipment (UE) conformance specification
7.3A.1 General
For NR CA operation NR single carrier REFSENS requirements defined in TS 38.101-1 [2] and TS 38.101-2 [3] apply to all downlink bands part of NR CA configurations listed in Table 5.2A.1-1 unless sensitivity degradation is allowed as defined in clause 7.3A in TS 38.101-3 [4].
7.3A.2 Reference sensitivity power level for CA without EN-DC
7.3A.2.1 Test purpose
Same test purpose as in clause 7.3.2 in TS 38.521-1 [8] for NR FR1 carrier(s) and clause 7.3.2 in TS 38.521-2 [9] for NR FR2 carrier(s).
7.3A.2.2 Test applicability
The requirements in this test are not testable due to issues with combined testing of NR FR1 conducted mode with NR FR2 in radiated mode. Therefore, the conducted and radiated requirements are tested separately.
No test case details are specified. The NR/5GC requirements for receiver sensitivity power level apply and are tested in TS 38.521-1 [8] clauses 7.3 and 7.3A and TS 38.521-2 [9] clauses 7.3 and 7.3A.
7.3A.3 ΔRIB,c for CA without EN-DC
For the UE which supports inter-band NR CA configuration, the minimum requirement for reference sensitivity in clause 7.3.2 in TS 38.101-1 [2] and clause 7.3.2, 7.3A.2in TS 38.101-2 [3] shall be increased by the amount given in ΔRIB,c in Tables below. Unless otherwise stated, ΔRIB,c is set to zero.
In case the UE supports more than one of band combinations for CA, SUL or DC, and an operating band belongs to more than one band combinations then
– When the operating band frequency range is ≤ 1GHz, the applicable additional ∆RIB,c shall be the average value for all band combinations defined in clause 7.3A, 7.3B, 7.3C in this specification and 7.3A, 7.3B in TS 38.101-3 [4], truncated to one decimal place that apply for that operating band among the supported band combinations. In case there is a harmonic relation between low band UL and high band DL, then the maximum ΔRIB,c among the different supported band combinations involving such band shall be applied
– When the operating band frequency range is > 1 GHz, the applicable additional ΔRIB,c shall be the maximum value for all band combinations defined in clause 7.3A, 7.3B, 7.3C in this specification and 7.3A, 7.3B in TS 38.101-3 [4] for the applicable operating bands.
7.3A.3.1 ΔRIB,c for Inter-band CA between FR1 and FR2 without EN-DC
Unless otherwise stated, ΔRIB,c for NR FR1 band and FR2 band of inter-band CA defined in table 5.5A.1-1 is set to zero.
