Abstract: A method for an uplink transmission of a user equipment (UE) in a wireless communication system and the UE are provided. The method includes receiving, from a base station (BS), control signaling; grouping physical downlink shared channels (PDSCHs) based on the control signaling; determining a hybrid automatic repeat request acknowledgement/negative acknowledgement (HARQ-ACK/NACK) codebook for each grouping of the PDSCHs; and transmitting HARQ-ACK/NACK information corresponding to the HARQ-ACK/NACK codebook. The UE includes a transceiver configured to receive control signaling from a BS; and a processor configured to: group PDSCHs based on the control signaling; and determine an HARQ-ACK/NACK codebook for each group of PDSCHs, wherein the transceiver is further configured to transmit HARQ-ACK/NACK information corresponding to the HARQ-ACK/NACK codebook.

Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). Embodiments of the present disclosure provide a channel state information measurement method, including: receiving, by a user equipment (UE), resource indication information for a CSI measurement; performing, by the UE, the CSI measurement according to the resource indication information, and transmitting a Channel Quality Indicator (CQI) report to a control node. According to the present disclosure, users may be scheduled by the base station more effectively and the efficiency of the whole network may be increased.

Abstract: The present application discloses a method and apparatus for a hybrid automatic repeat request (HARQ) transmission. An embodiment of the HARQ transmission method for the communication apparatus comprises: receiving configuration information related to a cross-carrier HARQ transmission from a base station, an initial transmission and a re-transmission of the HARQ transmission processable on different physical component carriers; receiving downlink control information from the base station, the downlink control information including control information for the cross-carrier HARQ transmission; and performing the cross-carrier HARQ transmission according to the configuration information and the downlink control information. By using the embodiments of the present invention, the HARQ transmission for the same data on a plurality of physical component carriers can be realized, and thus the effectiveness of the HARQ transmission is improved.

Abstract: The present disclosure provides several methods, user equipment (UEs) and base stations for transmitting uplink signals. After receiving uplink synchronization command information, the UE may transmit an uplink signal on at least one idle unlicensed cell. Besides, the UE may try to transmit the uplink signal on multiple uplink signal resources within an uplink signal transmission window. By using the present disclosure, transmission probability of uplink signals may be improved, and time delay of uplink synchronization may be shortened.
