CPC H04W 36/302 (2023.05) [H04W 36/0072 (2013.01)] | 20 Claims |
1. A device, comprising:
a processing system including a processor; and
a memory that stores executable instructions that, when executed by the processing system, facilitate performance of operations, the operations comprising:
selecting, at a network element of a wireless communication network, a neighboring cell as a handover candidate to begin communication as a target cell with a user equipment (UE) device, the UE device currently communicating with a source cell of the wireless communication network, wherein the source cell includes a source group of cells including a source primary cell (PCell) and one or more source secondary cells (SCells), wherein the UE device receives a respective source carrier from each respective cell of the source group of cells in a carrier aggregation arrangement, wherein the neighboring cell includes a target group of cells including a target PCell and one or more target SCells, and wherein the UE device is configured to receive a respective target carrier from each respective cell of the target group of cells following a handover of communication from the source cell to the target cell;
determining a total source bandwidth, wherein the total source bandwidth includes a sum of respective bandwidth values of each respective source carrier;
determining a total target bandwidth, wherein the total target bandwidth includes a sum of respective bandwidth values of each respective target carrier;
determining, for each respective source carrier, a respective Reference Signal Received Power (RSRP) value and a respective Signal to Noise Ratio (SNR) value;
determining, for each respective target carrier, a respective RSRP value and a respective SNR value;
identifying, as an improved RSRP target carrier, each respective target carrier having a respective RSRP value exceeding a respective RSRP value for a respective source carrier by a predetermined RSRP threshold;
identifying, as an improved SNR target carrier, each respective target carrier having a respective SNR value exceeding a respective SNR value for a respective source carrier by a predetermined SNR threshold;
combining respective bandwidth values of each improved RSRP target carrier, forming an improved RSRP carrier bandwidth;
combining respective bandwidth values of each improved SNR target carrier, forming an improved SNR carrier bandwidth;
comparing the RSRP carrier bandwidth with a carrier RSRP handover threshold;
comparing the SNR carrier bandwidth with a carrier SNR handover threshold; and
initiating the handover of communication from the source cell to the target cell, wherein the initiating the handover is responsive to
the RSRP carrier bandwidth exceeding the RSRP handover threshold, and
the SNR carrier bandwidth exceeding the SNR handover threshold.
