Abstract
Technology for a user equipment (UE) to communicate in a multiple radio access technology (multi-RAT) heterogeneous network (HetNet) is described. A radio-link-selection hysteresis threshold can be determined at the UE for a radio link between the UE and a node in the multi-RAT HetNet. A reliability value of a throughput estimate can be measured for the radio link in the multi-RAT HetNet. The radio-link-selection hysteresis threshold can be adjusted at the UE based on the reliability value to increase network stability in the multi-RAT HetNet.
Claims25
A user equipment (UE) in a multiple radio access technology (multi-RAT) heterogeneous network (HetNet), the UE having computer circuitry comprising:
- memory;
- and a processor coupled to the memory, configured to:
- determine, at the UE, a radio-link-selection hysteresis threshold of a radio link between the UE and a node in the multi-RAT HetNet;
- measure a reliability value of a throughput estimate for the radio link in the multi-RAT HetNet;
- and
- adjust the radio-link-selection hysteresis threshold at the UE based on the reliability value to increase network stability in the multi-RAT HetNet.
A node in a multiple radio access technology (multi-RAT) heterogeneous network (HetNet), the node having computer circuitry comprising:
- memory;
- and a processor coupled to the memory, configured to:
- determine, at the node, a radio-link-selection hysteresis threshold for the radio link in the multi-RAT HetNet;
- receive a reliability report from a user equipment (UE) for a data throughput estimate of the radio link between the UE and the node;
- adjust the radio-link-selection threshold at the node based on reliability report;
- and
- communicate the adjusted radio-link-selection threshold to the UE in the multi-RAT HetNet.
At least one non-transitory machine readable storage medium having instructions embodied thereon for adjusting a node-selection threshold for a node in a multiple radio access technology (multi-RAT) heterogeneous network (HetNet), the instructions that when executed by at least one processor perform the following:
- select, at the UE, a node-selection hysteresis threshold for the node in the multi-RAT HetNet;
- determining a reliability value for a threshold throughput estimate between the UE and the node in the multi-RAT HetNet;
- and
- adjusting the node-selection threshold at the UE based on the reliability value.
