METHOD AND APPARATUS FOR HYBRID AUTOMATIC REPEAT REQUEST SIGNALING FOR CARRIER AGGREGATION

摘要

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.
