USER EQUIPMENT (UE), EVOLVED NODE-B (ENB) AND HYBRID AUTOMATIC REPEAT REQUEST (HARQ) METHODS FOR CARRIER AGGREGATION ARRANGEMENTS

摘要

Embodiments of a User Equipment (UE), Evolved Node-B (eNB) and methods for communication in accordance with hybrid automatic repeat request (HARQ) operation are generally described herein. In a sub-frame, the UE may receive, from an eNB on multiple component carriers (CCs) of a carrier aggregation (CA), one or more physical downlink control channels (PDCCHs) and one or more physical downlink shared channel (PDSCH) transmissions scheduled by the PDCCHs. The UE may receive a semi-persistent scheduling (SPS) PDSCH transmission scheduled in the sub-frame by an SPS schedule configured prior to the sub-frame. HARQ-ACK bits for the PDSCH transmissions may be mapped to bit positions of a HARQ-ACK bit sequence indicated by the PDCCHs. A HARQ-ACK bit for the SPS PDSCH transmission may be mapped to a predetermined bit position of the HARQ-ACK bit sequence reserved for the SPS PDSCH transmission.
