1. An apparatus, comprising:
at least one processor; and
at least one memory including computer program code;
the at least one memory and the computer program code being configured to, with the at least one processor, cause the apparatus at least to:
transmit a beam report to a network to indicate an association between at least two downlink reference signals and at least two active antenna panels at the apparatus or to indicate a selection of at least two downlink reference signals that will be used for downlink reception at the apparatus simultaneously;
detect beam failure based on at least two sets of beam failure detection resources for the at least two active antenna panels, wherein the at least two sets of beam failure detection resources comprise one or more beam failure detection reference signals; and
determine to divide the downlink reference signals indicated by the transmission configuration indicator (TCI) states for respective control resource sets (CORESETs) into respective subsets according to a predefined rule, and determine the downlink reference signals according to the predefined rule of control resource sets (CORESETs) indexing.
