NOTE 1: When in dBm/15kHz, the minimum Io condition is expressed as the average Io per RE over all REs in that symbol. Io may be different in different symbols within a subframe. NOTE 2: Ts is the basic timing unit defined in TS 36.211 [26]. NOTE 3: The same bands and the same Io conditions for each band apply for this requirement as for the corresponding requirement with downlink bandwidth ≥1.4 MHz. NOTE 4: Except Band 29. NOTE 5: The condition level is increased by ∆>0, when applicable, as described in TS 36.521-3 [25] Sections I.4.2 and I.4.3. NOTE 6: E-UTRA operating band groups are as defined in Section 4.4.2. NOTE 7: Except Band 32. |
