The present document is a technical report for release 18 basket WI High power UE (power class 1.5 or 2) for intra-band Carrier Aggregation combinations of a single NR FR1 TDD band.

The following documents contain provisions which, through reference in this text, constitute provisions of the present document.

• References are either specific (identified by date of publication, edition number, version number, etc.) or non-specific.
• For a specific reference, subsequent revisions do not apply.
• For a non-specific reference, the latest version applies. In the case of a reference to a 3GPP document (including a GSM document), a non-specific reference implicitly refers to the latest version of that document in the same Release as the present document.

At 3GPP RAN#97-e meeting, a basket Work Item on "High power UE (power class 1.5 or 2) for intra-band Carrier Aggregation combinations of a single NR FR1 TDD band" [2] was approved for Rel-18. The objectives of the core part are as follows: This WI will address the following intra-band Carrier Aggregation cases of a single NR FR1 TDD band:

• with PC2 for UL intra-band CA configuration
• with PC2 for single uplink carrier
• with PC1.5 for single uplink carrier
• with the following objectives:
  1. Specify the band-combination specific RF requirements including
     1. UE maximum output power and Tx power tolerance
     2. A-MPR requirements if needed
  2. Define requirements for PC1.5 according to following conditions
     1. Include intra-band DL CA band combinations with PC1.5 on the single carrier uplink in supporting of 2x26dBm PA configuration.

The NR intra-band CA band combination configurations of frequency range FR1 that are considered in this WI are defined in the Table 1 below:

The present document is a technical report for this basket Work Item.
