1. A method, comprising:
informing a network element about a user equipment type and capability in beam switching from a source beam to a target beam;
receiving a request from the network element to switch from the source beam to the target beam;
based on the user equipment type and capability, receiving a reference signal for time or frequency tracking with the target beam;
switching from the source beam to the target beam; and
adjusting the time or frequency tracking of the target beam after the switching based on the reference signal.
 
14. An apparatus, comprising:
at least one processor; and
at least one memory comprising computer program code,
the at least one memory and the computer program code are configured, with the at least one processor to cause the apparatus at least to
receive an indication from a user equipment identifying a user equipment type and capability in beam switching between a source beam and a target beam;
select the user equipment for configuration for time or frequency tracking based on the user equipment type;
transmit a request to the user equipment to switch from a source beam to a target beam;
determine whether to transmit a reference signal to the user equipment for time or frequency tracking with the target beam based on the user equipment type and capability; and
receive communication from the user equipment via the target beam.
