Method for managing multiple timing advance loops

An apparatus, comprising at least one processor;

• and at least one memory including instructions, the at least one memory and the instructions configured to, with the at least one processor, to cause the apparatus at least to:
• transmit, to a network node, an indication that a plurality of timing advance loops are supported;
• receive, from the network node, a configuration for measuring downlink reference signals;
• perform measurements on the downlink reference signals according to the configuration;
• determine, based on the measurements, that at least one additional timing advance loop is needed for transmission of a plurality of candidate uplink beams;
• and
• transmit, to the network node, an indication that at least one additional timing advance loop is needed for transmission of the plurality of candidate uplink beams.
