Beam group specific mobility robustness optimization

A method comprising:

• associating communication beams into at least two different groups, where at least one of the groups has at least two of the communication beams;
• based upon beam-group specific key performance indicators, where the beam-group specific key performance indicators have been based upon the associating of the communication beams into the at least two different groups, using the beam-group specific key performance indicators to determine at least one beam-group specific mobility parameter for at least one of the groups of communication beams;
• wherein the at least one beam-group specific mobility parameter comprises a first cell individual offset and a second cell individual offset;
• increasing the first cell individual offset for a first group of beams associated with a first geographical area comprising at least one faster moving user equipment relative to at least one slower moving user equipment of a second geographical area;
• and
• decreasing the second cell individual offset for a second group of beams associated with the second geographical area comprising the at least one slower moving user equipment relative to the at least one faster moving user equipment of the first geographical area;
• and
• transmitting the at least one beam-group specific mobility parameter to a base station;
• wherein the at least one beam-group specific mobility parameter is related to handover initiation.

A non-transitory program storage device readable by a machine, tangibly embodying a program of instructions executable by the machine for performing operations, the operations comprising:

• associating communication beams into at least two different groups, where at least one of the groups has at least two of the communication beams;
• based upon beam-group specific key performance indicators, where the beam-group specific key performance indicators have been based upon the associating of the communication beams into the at least two different groups, using the beam-group specific key performance indicators to determine at least one beam-group specific mobility parameter for at least one of the groups of communication beams;
• wherein the beam-group specific key performance indicators used to determine the at least one beam-group specific mobility parameter comprise statistics related to handover initiation performed too early or too late;
• and
• cause transmitting of the at least one beam-group specific mobility parameter to a base station;
• wherein the at least one beam-group specific mobility parameter is related to handover initiation.
