In certain embodiments, common beam and E-tilt are additional parameters that can be optimized to improve the cellular performance. Changing the E-tilt or common beam of a cell will change the cellular coverage and further affect the cell performance. For example, when gNB 102 can transmits 705 with an E-tilt set at 9°, gNB 102 is able to cover a first cell area 710. Alternatively, when gNB 102 can transmits 705 with an E-tilt set at 4°, gNB 102 is able to cover a second cell area 715.

FIG. 8 illustrates example base station according to embodiments of the present disclosure. The embodiment of the base station 800 shown if for illustration only and other embodiments could be used without departing from the scope of the present disclosure. The base station 800 shown in FIG. 8 can configured the same as, or similar to, gNB 102 or gNB 103 in FIG. 1.

The base station 800 includes a digital unit (DU) 805, or baseband unit, comprising processors, filters, memory and programming for performing the functions for supporting cellular communications. The base station 800 also includes one or more remote radio heads (RRH) 810, which can include one or more transceivers, transmit paths, and receive paths, such as transmit path 400 and receive path 450 in FIGS. 4A and 4B. Each or the RRH 810 is coupled to a respective antenna 815, which can include one or more antenna elements, and can be configured as an antenna array having one or more antennas. The base station 800 further includes an agent 820.
