7.6.1EC In-band blocking for UE category M2
36.521-13GPPEvolved Universal Terrestrial Radio Access (E-UTRA)Part 1: Conformance testingRadio transmission and receptionRelease 17TSUser Equipment (UE) conformance specification
7.6.1EC.1 Test purpose
In-band blocking is defined for an unwanted interfering signal falling into the range from 15MHz below to 15MHz above the category M2 UE receive band, at which the relative throughput shall meet or exceed the requirement for the specified measurement channels.
The lack of in-band blocking ability will decrease the coverage area when other e-NodeB transmitters exist (except in the adjacent channels and spurious response).
7.6.1EC.2 Test applicability
This test applies to all types of E-UTRA UE release 14 and forward of category M2.
7.6.1EC.3 Minimum conformance requirements
The throughput shall be ≥ 95% of the maximum throughput of the reference measurement channels as specified in Annexes A.2.2, A.2.3 and A.3.2 (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 Tables 7.6.1EC.3-1 and 7.6.1EC.3-2. For operating bands with an unpaired DL part (as noted in Table 5.2-1), the requirements only apply for carriers assigned in the paired part.

NOTE 1: The transmitter shall be set to 4dB below PCMAX_L at the minimum uplink configuration specified in Table 7.3EA-3 with PCMAX_L as defined in subclause 6.2.5EA. NOTE 2: The interferer consists of the Reference measurement channel specified in Annex A.3.2 with one sided dynamic OCNG Pattern OP.1 FDD/TDD as described in Annex A.5.1.1/A.5.2.1 and set-up according to Annex C.3.1. NOTE 3: For DL category M1 and M2 UE, the reference sensitivity for category M1 in table 7.3EA-1 and 7.3EA-2 and category M2 in Table 7.3EC-1 should be used as REFSENS for the power in Transmission Bandwidth Configuration. NOTE 4: For DL category M1 and M2 UE, the parameters for the applicable channel bandwidth apply. |

NOTE 1: For certain bands, the unwanted modulated interfering signal may not fall inside the UE receive band, but within the first 15 MHz below or above the UE receive band NOTE 2: For each carrier frequency the requirement is valid for two frequencies: a. the carrier frequency -BW/2 – FIoffset, case 1 and b. the carrier frequency +BW/2 + FIoffset, case 1 NOTE 3: FInterferer range values for unwanted modulated interfering signal are interferer centre frequencies |
