1. A system, comprising:
at least one processor; and
at least one memory that stores executable instructions that, when executed by the at least one processor, facilitate performance of operations, the operations comprising:
obtaining a time alignment value corresponding to a time difference between a first time at which a user equipment is to receive a first transmission from a first cell and a second time at which the user equipment is to receive a second transmission from a second cell, wherein the first cell and the second cell correspond to a first transmission point and a second transmission point, respectively, and wherein the first cell and the second cell are operating in a coordinated multipoint transmission and reception configuration; and
adjusting, based on the time alignment value, a third transmission from the first cell to result in the user equipment receiving the third transmission in alignment with the user equipment receiving a fourth transmission from the second cell,
wherein the adjusting of the third transmission comprises changing a downlink frame boundary of the first cell, and
wherein the downlink frame boundary remains in use for a duration corresponding to a defined number of transmission slots.
