摘要： Devices and methods of reducing blind decoding attempts of user equipment (UE) suing carrier aggregation are generally described. The UE may determine at least one subframe in a modification period to monitor for a physical downlink control channel (PDCCH) formed in accordance with a Discontinuous Transmission Downlink Control Information (DTX DCI) format. The DTX DCI format may indicate whether the serving cell is in a DTX or non-DTX state. The UE may determine the DTX state of each serving cell from the DTX DCI format and monitor an enhanced PDCCH of each serving cell in the non-DTX state to provide a scheduling assignment for the UE, without monitoring each serving cell in the DTX state. The UE may receive higher layer signaling that indicates a repetition period and subframe offset for DTX DCI format transmissions or a bitmap of the DTX DCI format transmissions for subframes within each modification period.

摘要： Devices and methods of reducing overall Hybrid Automatic Repeat Request-Acknowledgment (HARQ-ACK) of user equipment (UE) using a large amount of carrier aggregation are generally described. The UE may receive a subframe from an enhanced NodeB (eNB). The subframe may contain a physical downlink control channel (PDCCH) formed in accordance with a Downlink Control information (DCI) format. The DCI format may comprise a Downlink Assignment Index (DAI) for Time Division Duplexed (TDD) and Frequency Division Duplexed (FDD) operation. The UE may determine, dependent on the DAI, a number and ordering of Hybrid Automatic Repeat Request-Acknowledgment (HARQ-ACK) bits to be transmitted on a Physical Uplink Shared Channel (PUSCH) and subsequently transmit the HARQ-ACK bits.

摘要： An apparatus and method for transmitting and receiving packet data in a mobile communication system supporting Hybrid Automatic Repeat reQuest (HARQ), e.g., a method and apparatus for performing HARQ retransmission on a packet received through persistent resources where no HARQ process identifier is transmitted. HARQ soft combining is performed by providing a mapping relation between a packet received through persistent resources and a retransmitted HARQ packet. In addition, when there are several HARQ packets received through persistent resources at an arbitrary timing, which packet an arbitrary retransmission packet should be combined is determined, thereby enabling the corresponding processor to perform correct soft combining This improves HARQ performance of persistent resources without increasing complexity of the reception apparatus.
