1. A system, comprising:
a memory that stores executable components; and
a processor that executes the executable components stored in the memory, wherein the executable components comprise:
an offset estimation component that determines an estimated time offset between a first time, at which a user equipment receives a first transmission from a first cell of a communication network, and a second time, at which the user equipment receives a second transmission from a second cell of the communication network; and
a phase rotation component that adjusts a first phase of a third transmission, to be transmitted by the first cell to the user equipment, relative to the first transmission by a rotation amount determined as a function of the estimated time offset, resulting in the first phase of the third transmission being aligned with a second phase of a fourth transmission, to be transmitted by the second cell to the user equipment and offset in time relative to the third transmission by the estimated time offset.
