Abstract

An evolved Node B (eNB) for sending feedback information is described. The eNB includes a processor and instructions stored in memory that is in electronic communication with the processor. The eNB determines configuration parameters related to an Enhanced Physical Hybrid-Automatic Repeat reQuest (ARQ) Indicator Channel (EPHICH). The eNB also sends a configuration signal based on the configuration parameters. The eNB additionally receives data in a Physical Uplink Shared Channel (PUSCH). The eNB further sends Hybrid Automatic Repeat Request Acknowledgement/Negative Acknowledgement (HARQ-ACK) information based on the configuration parameters.
