7.5A.1 Adjacent Channel Selectivity (ACS) for CA (intra-band contiguous DL CA and UL CA)
36.521-13GPPEvolved Universal Terrestrial Radio Access (E-UTRA)Part 1: Conformance testingRadio transmission and receptionRelease 17TSUser Equipment (UE) conformance specification
7.5A.1.1 Test purpose
Adjacent channel selectivity for CA test verifies the UE’s ability to receive data with a given average throughput for a specified reference measurement channel, in the presence of an adjacent channel signal at a given frequency offset from the centre frequency of the assigned channel, under conditions of ideal propagation and no added noise.
A UE unable to meet the throughput requirement under these conditions will decrease the coverage area when other e-NodeB transmitters exist in the adjacent channel.
7.5A.1.2 Test applicability
This test applies to all types of E-UTRA UE release 10 and forward that support intra-band contiguous DL CA and UL CA.
7.5A.1.3 Minimum conformance requirements
The minimum conformance requirements are defined in clause 7.5A.0.
7.5A.1.4 Test description
7.5A.1.4.1 Initial conditions
Initial conditions are a set of test configurations the UE needs to be tested in and the steps for the SS to take with the UE to reach the correct measurement state.
The initial test configurations consist of environmental conditions, test frequencies, and channel bandwidths based on E-UTRA CA configurations specified in table 5.4.2A.1-1. All of these configurations shall be tested with applicable test parameters for each channel bandwidth, and are shown in table 7.5A.1.4.1-1. The details of the uplink and downlink reference measurement channels (RMCs) are specified in Annexes A.2 and A.3 respectively. The details of the OCNG patterns used are specified in Annex A.5. Configurations of PDSCH and PDCCH before measurement are specified in Annex C.2.

Note 1: CA Configuration Test CC Combination settings are checked separately for each CA Configuration, which applicable aggregated channel bandwidths are specified in Table 5.4.2A.1-1. Note 2: Depending on CA configurations, only the appropriate Uplink RB allocation value according to table 7.3.3-2 for UE supporting one uplink carrier and to table 7.3A.0-1 for UE supporting two uplink carriers are tested per Test CA configuration. Note 3: If the UE supports multiple CC Combinations in the CA Configuration with the same NRB_agg , only the combination with the highest NRB_PCC is tested. |

1. Connect the SS and interfering source to the UE antenna connectors as shown in TS 36.508 [7] Annex A, Figure group A.34 as appropriate if the UE supports 2 Rx antennas or Figure A.82 if the UE supports 4 Rx antennas in the band.
2. The parameter settings for the cell are set up according to TS 36.508 [7] clause 4.4.3.
3. Downlink signals for PCC are initially set up according to Annex C.0, C.1 and C.3.0, and uplink signals according to Annex H.1 and H.3.0.
4. The UL and DL Reference Measurement channels are set according to Table 7.5A.1.4.1-1.
5, Propagation conditions are set according to Annex B.0.
6. Ensure the UE is in State 3A-RF according to TS 36.508 [7] clause 5.2A.2. Message contents are defined in clause 7.5A.1.4.3.
7.5A.1.4.2 Test procedure
1. Configure SCC according to Annex C.0, C.1 and Annex C.3.1 for all downlink physical channels.
2. The SS shall configure SCC as per TS 36.508 [7] clause 5.2A.4. Message contents are defined in clause 7.5A.1.4.3.
3. SS activates SCC by sending the activation MAC-CE (Refer TS 36.321 [13], clauses 5.13, 6.1.3.8). Wait for at least 2 seconds (Refer TS 36.133, clauses 8.3.3.2).
4. SS transmits PDSCH via PDCCH DCI format 1A for C_RNTI to transmit the DL RMC according to Tables 7.5A.1.4.1-1 on both PCC and SCC. The SS sends downlink MAC padding bits on the DL RMC.
5. SS sends uplink scheduling information for each UL HARQ process via PDCCH DCI format 0 for C_RNTI to schedule the UL RMC according to Table 7.5A.1.4.1-1 on both PCC and SCC. Since the UE has no payload and no loopback data to send the UE sends uplink MAC padding bits on the UL RMC.
6. Set the Downlink signal level for PCC and SCC to the value as defined in Table 7.5A.1.5-2 (Case 1). Send Uplink power control commands to the UE (less or equal to 1dB step size should be used), to ensure that for at least the duration of the Throughput measurement:
The PCC output power is within (+0dB, -3.4 dB) of (target level in Table 7.5A.1.5-2 (Case 1) + 10log(P_LCRB/NRB_alloc)), for carrier frequency f ≤ 3.0GHz,
or within (+0dB, -4 dB) of (target level in Table 7.5A.1.5-2 (Case 1) + 10log(P_LCRB/NRB_alloc)) for carrier frequency 3.0GHz < f ≤ 4.2GHz.
The SCC output power is within (+0dB, -3.4 dB) of (target level in Table 7.5A.1.5-2 (Case 1) + 10log(S_LCRB/NRB_alloc)), for carrier frequency f ≤ 3.0GHz,
or within (+0dB, -4 dB) of (target level in Table 7.5A.1.5-2 (Case 1) + 10log(S_LCRB/NRB_alloc)) for carrier frequency 3.0GHz < f ≤ 4.2GHz.
7. Set the Interferer signal level to the value as defined in Table 7.5A.1.5-2 (Case 1) and frequency below the wanted signal, using a modulated interferer bandwidth as defined in Annex D of the present document. The interferer frequencies are adjusted in analogy with table 7.5A.1.4.2-1.
8. Measure the average throughput for each component carrier for a duration sufficient to achieve statistical significance according to Annex G.2A.
9. Repeat steps from 6 to 8, using an interfering signal above the wanted signal in Case 1 at step 7.
10. Set the Downlink signal level for PCC and SCC to the value as defined in Table 7.5A.1.5-3 (Case 2). Send Uplink power control commands to the UE (less or equal to 1dB step size should be used), to ensure that for at least the duration of the Throughput measurement:
The PCC output power is within (+0dB, -3.4 dB) of (target level in Table 7.5A.1.5-3 (Case 2) + 10log(P_LCRB/NRB_alloc)), for carrier frequency f ≤ 3.0GHz,
or within (+0dB, -4 dB) of (target level in Table 7.5A.1.5-3 (Case 2) + 10log(P_LCRB/NRB_alloc)) for carrier frequency 3.0GHz < f ≤ 4.2GHz.
The SCC output power is within (+0dB, -3.4 dB) of (target level in Table 7.5A.1.5-3 (Case 2) + 10log(S_LCRB/NRB_alloc)), for carrier frequency f ≤ 3.0GHz,
or within (+0dB, -4 dB) of (target level in Table 7.5A.1.5-3 (Case 2) + 10log(S_LCRB/NRB_alloc)) for carrier frequency 3.0GHz < f ≤ 4.2GHz.
11. Set the Interferer signal level to the value as defined in Table 7.5A.1.5-3 (Case 2) and frequency below the wanted signal, using a modulated interferer bandwidth as defined in Annex D of the present document. The interferer frequencies are adjusted in analogy with table 7.5A.1.4.2-1.
12. Measure the average throughput for each component carrier for a duration sufficient to achieve statistical significance according to Annex G.2A.
13. Repeat steps from 10 to 12, using an interfering signal above the wanted signal in Case 2 at step 11.
