Multi-frequency data communication service over multiple wireless access nodes

Abstract

A wireless communication network delivers multi-frequency service to User Equipment (UE). A primary node receives signaling from the UE that indicates secondary nodes along with their frequencies and signal strengths. The primary node selects candidate nodes based on the signal strengths for the secondary nodes. The primary node determines potential intermodulation interference between the primary frequency and the frequencies for the candidate set. The primary node selects a qualifying set from the candidate set based on the potential intermodulation interference. The primary node determines communication performance for the qualifying set and selects a serving set from the qualifying set based on the communication performance. The primary node wirelessly transfers signaling to the UE identifying the serving set and transfers signaling to the serving set identifying the UE. The serving set of secondary access nodes wirelessly transfer user data to the UE over their frequencies responsive to the signaling.
