1 Scope p. 7
The present document is a technical report for High power UE (power class 2) for NR FR1 FDD single band under Rel-18 time-frame. The purpose is to gather the relevant background information and studies in order to complete the band specific requirements for the newly requested band combinations for power class 2 UE under FDD mode.

4 Background p. 8
At 3GPP RAN4#97-e meeting, a basket Work Item on "High power UE (power class 2) for NR FR1 FDD single band" was approved for Rel-18. The objectives of the core part are as follows:
The objectives of the core part are as follows:
- Scope of this basket WI includes NR FDD bands
-
Specify the band specific RF requirements for all listed power class 2 NR FDD bands including
- UE maximum output power and Tx power tolerance
- A-MPR requirements if needed
- PC2 sensitivity degradation requirements if needed
4.1 TR Maintenance p. 8
A single company is responsible for introducing all approved TPs in the current TR, i.e. TR editor. However, it is the responsibility of the contact person of each band/band combination to ensure that the TPs related to the band/band combination have been implemented.
