Question: For a User Equipment (UE) to support Narrowband Internet of Things (NB-IoT) with a power class of 20dBm, which of the following specifications would be relevant for understanding the radio transmission and reception requirements for both terrestrial and satellite access?
Option 1: TS 36.101 alone, as it covers all aspects of E-UTRA.
Option 2: Only TS 36.102, since NTN (Non-Terrestrial Network) capability is mentioned.
Option 3: Neither TS 36.101 nor TS 36.102, as power class specifics are not covered in these specs.
Option 4: Both TS 36.101 for terrestrial E-UTRA and TS 36.102 for satellite access (NTN capable UE).
Explanation: To fully understand the requirements for a UE supporting NB-IoT with a power class of 20dBm, especially when considering NTN capability which implies satellite access, one needs to refer to both specifications. TS 36.101 provides insights into terrestrial radio transmission and reception, while TS 36.102 specifically addresses these aspects for satellite access, making both essential for comprehensive understanding.
