1. A baseband processor of a user equipment (UE) configured to perform operations comprising:
determining, during secondary cell (SCell) activation, that beam information to enable the UE to make a reliable layer 1 (L1)-Reference Signal Received Power (RSRP) measurement for beam reporting is unavailable, including determining that the SCell being activated belongs to Frequency Range 2 (FR2) and that the SCell is unknown to the UE, to determine that the beam information is unavailable;
performing, when the beam information to enable the UE to make the reliable L1-RSRP measurement is unavailable, the L1-RSRP measurement using preconfigured transmission configuration indicator (TCI) information for L1-RSRP that is preconfigured by a network during the SCell activation; and
reporting, to the network after SCell synchronization, the L1-RSRP measurement made with the preconfigured TCI information as alternative information for beam reporting in a L1-RSRP measurement report for the SCell activation as a replacement.
