Abstract:
A method at a user equipment for hybrid automatic repeat request (HARQ) operation, the user equipment operating on a primary carrier having a first duplex mode and on at least one secondary carrier having a second duplex mode, the method using HARQ timing of the first duplex mode if the timing of the first duplex mode promotes acknowledgement opportunities over using HARQ timing of the second duplex mode; and using HARQ timing of the second duplex mode if the timing of the second duplex mode promotes acknowledgement opportunities over using HARQ timing of the first duplex mode.
