Method and apparatus for coding of harq-ack transmission in tdd systems with downlink carrier aggregation

摘要

Methods and apparatus are provided for a User Equipment (UE) configured with multiple cells in a DownLink (DL) of a Time Division Duplex (TDD) communication system to determine the coding method for acknowledgement information bits as a function of their number, to apply bundling to the acknowledgement information bits when their number exceeds a first predetermined value, and to partition the acknowledgement information bits, possibly together with other control information bits, into two separate codewords when their total number exceeds a second predetermined value.
