Abstract
An eNodeB (eNB), user equipment (UE) and method for operating in enhanced coverage (EC) modes are generally described. The UE may determine whether or not a physical uplink control channel (PUCCH) signal and an uplink signal allocated to different resources in a particular subframe overlap. The uplink signal may comprise another PUCCH signal or a physical uplink shared channel (PUSCH) signal. The PUCCH signals may comprise a scheduling request or acknowledgement response/retransmission request. The UE may select one of the overlapping signals and transmit the selected signal on a resource allocated to the other signal instead of on a resource allocated to the one of the overlapping signals. The other signal may or may not be transmitted dependent on whether it is a PUCCH or PUSCH signal.
