Wireless base station to control an integrated long term evolution and new radio (LTE/NR) antenna array

摘要

An antenna array in a wireless base station has a New Radio (NR) portion and a Long Term Evolution (LTE) portion. Baseband circuitry determines NR User Equipment (UE) loading and LTE UE loading on the antenna array. The baseband circuitry determines an NR power level and an LTE power level based on the NR UE loading and the LTE UE loading. Radio circuitry drives the NR portion of the antenna array at the NR power level and drives the LTE portion of the antenna array at the LTE power level. The baseband circuitry may also re-allocate antenna elements between the NR elements and the LTE elements in the antenna array based on antenna element loss, UE loading, and control channel usage. The baseband circuitry may also separately implement Multi-User Multiple Input Multiple Output (MU-MIMO) on the NR and LTE portions of the antenna array.
