An Enhanced Physical Downlink Control Channel (EPDCCH) is detected in signals received from a base station in a first subframe. A HARQ-ACK resource indicator offset (ΔARO) value is identified for the EPDCCH. A PUCCH resource is selected for transmission of a Hybrid Automatic Repeat reQuest-ACKnowledgement (HARQ-ACK) corresponding to the EPDCCH. The PUCCH resource is selected based upon the ΔARO value. The ΔARO value may correspond to a semi-statically configured PUCCH resource. A second PUCCH resource may be selected for transmission of the HARQ-ACK on a second antenna port. A HARQ-ACK resource offset field value may be detected in a Downlink Control Information (DCI) format of the EPDCCH. A table that maps the HARQ-ACK resource offset field value for certain DCI formats to ΔARO values may be used to determine the ΔARO value for the EPDCCH."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Efficient allocation of uplink HARQ-ACK resources for LTE enhanced control channel","description":"Systems and methods for selecting Physical Uplink Control Channel (PUCCH) resources are disclosed.
