Original Abstract Submitted
Correction of downlink radio frame misalignment for coordinated multi-point transmission/reception (COMP) by phase rotation is described herein. A method as described herein can include estimating a time offset between a first time, at which a first transmission is received by a user equipment (UE) from a first cell, and a second time, at which a second transmission is received by the UE from a second cell; determining a phase rotation value based on the time offset; and adjusting a first phase of a third transmission, to be transmitted by the first cell to the UE, relative to the first transmission based on the phase rotation value, 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 UE and offset in time relative to the third transmission by the time offset.
