1. A method comprising:
establishing multiple connections in a primary cell and one or more secondary cells by a user equipment (UE) in a beamforming communication network, wherein the UE is configured to operate under one or multiple frequency bands with carrier aggregation or dual connectivity;
determining a number of frequency bands on which the UE is configured to perform beam failure recovery detection (BFD) only for at least one of the one or more secondary cells;
determining a sharing factor based on the number of frequency bands; and
performing BFD or candidate beam identification (CBD) on the primary cell using a first evaluation period and on the at least one of the one or more secondary cells using a second evaluation period, wherein the second evaluation period is determined based on the first evaluation period times the sharing factor.
