Claim 8:
9. A method, performed by a target node, for beam-level mobility load balancing (MLB) in a radio access network (RAN), the method comprising:
exchanging beam-level load information with a source node in the RAN; and
receiving, from the source node, a request including one or more first handover offsets to be applied during MLB operations between:
a group of one or more source beams associated with the source node, including a particular source beam serving a first plurality of user equipment (UEs); and
a group of one or more target beams associated with the target node; and

transmitting, to the source node, a response including one of the following:
an acknowledgement that the one or more first handover offsets will be applied; or
one or more second handover offsets to be applied instead of the one or more first handover offsets, wherein:

the request is a Handover Request for a subset of the first plurality of UEs to a particular one of the group of one or more target beams; and
the response is one of the following messages: a Handover Request Acknowledge, and a Handover Preparation Failure.
