Abstract
Systems and methods provide inter-band EN-DC coverage combinations to wireless devices in a cell wherein each inter-band coverage has corresponding handover criteria. The method includes determining a power class for at least one wireless device, wherein the power class is one of a high-power class and a low power class. The method additionally includes comparing the handover criteria of at least two inter-band coverage combinations to identify relaxed handover criteria and assigning the high-power class wireless device to an inter-band coverage combination having the relaxed handover criteria.
Claims20
A method comprising:
- providing a plurality of access nodes configured to provide inter-band EN-DC coverage combinations to wireless devices in a cell, each inter-band coverage combination having corresponding handover criteria, the access nodes including at least a master node utilizing a first frequency band and a second frequency band and a secondary node;
- determining a power class for at least one wireless device, wherein the power class is one of a high-power class and a low power class;
- comparing the handover criteria of at least two inter-band coverage combinations to identify relaxed handover criteria, wherein the first frequency band is higher than the second frequency band and the master node stores more relaxed handover criteria for an inter-band coverage combination utilizing the second frequency band than for an inter-band coverage combination utilizing the first frequency band;
- and
- assigning the high-power class wireless device to the inter-band coverage combination having the relaxed handover criteria, the relaxed handover criteria determining assignment of the high-power class wireless device to the secondary node.

A system comprising:
- at least one access node configured to provide inter-band EN-DC coverage combinations to wireless devices in a cell, each inter-band coverage combination having corresponding handover criteria, wherein the access node is a master node utilizing a first frequency band and a second frequency band;
- at least one secondary node:
- a processor coupled to the access node configured to perform operations comprising,
- determining a power class for at least one wireless device, wherein the power class is one of a high-power class and a low power class;
- comparing the handover criteria of at least two inter-band coverage combinations to identify more relaxed handover criteria, wherein the first frequency band is higher than the second frequency band and the master node stores more relaxed handover criteria for an inter-band coverage combination utilizing the second frequency band than for an inter-band coverage combination utilizing the first frequency band;
- and
- assigning the high-power class wireless device to an inter-band coverage combination having the more relaxed handover criteria for determining assignment of the high-power class wireless device to the secondary node.
