Compliance with regional regulatory requirements for user equipment with positive antenna gain
Additional requirements for spectrum emissions may be matched with regional requirements, and an additional maximum power reduction (A-MPR) for a user equipment (UE) may be based on an actual antenna gain of the UE. For example, a UE may be located in a particular region and be required to meet regional requirements for wireless communications. In such cases, the UE may receive network signaling from a base station, and identify an antenna gain for its antenna. The UE may then identify a set of emission requirements based on the identified antenna gain and the network signaling. Additionally, the UE may identify an A-MPR based on the set of emission requirements and the antenna gain and may adjust a maximum output power in accordance with the identified A-MPR. In some examples, an output power threshold may be derived using a difference between a regional requirement and the UE's antenna gain.
