Abstract:
1. A method of operating a user equipment (UE) in a wireless communications network, the method comprising: determining, by the UE, downlink (DL) hybrid automatic repeat request (HARQ) timing linkages associated with each of a first component carrier and a second component carrier, the first component carrier having a different uplink (UL) and DL configuration than the second component carrier; determining, by the UE, a derived downlink association set in response to the DL HARQ timing linkages are related such that an uplink resource collision may occur, wherein the derived downlink association set comprises set values of a second downlink association set minus a union of a first downlink association set and the second downlink association set, where the first downlink association set is associated with the first component carrier and the second downlink association set is associated with the second component carrier; identifying, by the UE, a PUCCH resource in a subframe based on the first downlink association set and the derived downlink association set; and transmitting HARQ information using the PUCCH resource.
