Method and apparatus for hybrid automatic repeat request signaling
In one aspect, the teachings herein provide a system and method for reusing the PUCCH format 3 to address the new HARQ-ACK feedback cases encountered in Rel-11, where different UL/DL configurations are involved in the CA configuration of a UE, such as Rel-11 interband TDD CA with different UL/DL configurations on different bands. The various embodiments illustrated by way of example in this disclosure enable reliable and efficient HARQ-ACK feedback for Rel-11 TDD CA without a substantial increase in specification and implementation complexity.
