摘要： 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.

摘要： An apparatus and method for feeding back hybrid automatic repeat request-acknowledgement (HARQ-ACK) information are provided. The apparatus and method include user equipment (UE) that first receives a downlink grant (DL-GRANT) which schedules downlink HARQ transmission in a time-frequency bundling window corresponding to an uplink subframe used for feeding back HARQ-ACK, obtains a DL downlink assignment index (DL DAI) in the DL-GRANT, and determines a mapping value of each DL DAI. Then, according to the mapping value of the corresponding DL DAI, the HARQ-ACK bit of each HARQ feedback unit is mapped to a corresponding bit of a feedback bit sequence. According to the method and apparatus provided by the present disclosure, useless HARQ-ACK bits may be effectively removed, and efficiency for feeding back HARQ-ACK may be increased. As such, a downlink peak rate of a UE is ensured.

摘要： An uplink control information (UCI) transmitting method is provided. In this method, a user equipment (UE) receives a configuration signaling, determines a candidate physical uplink control channel (PUCCH) set corresponding to an acknowledgement (ACK)/negative acknowledgement (NACK) resource indication (ARI), receives a downlink grant signaling and downlink data corresponding to the downlink grant signaling, generates hybrid automatic repeat request ACK (HARQ-ACK) bits, performs processing for UCI bits including HARQ-ACK, determines the PUCCH used to transmit the UCI bits in the candidate PUCCH set according to an ARI in the downlink grant signaling, and transmits the UCI bits on the determined PUCCH. The present disclosure further provides an aperiodic channel state information (A-CSI) transmitting method. In this method, a UE receives an uplink grant signaling, determines whether an A-CSI report is triggered according to a CSI request field in the uplink grant signaling, determines a CSI process to be updated after determining that the A-CSI report is triggered, and transmits A-CSI on an uplink component carrier (CC) carrying the A-CSI report.

摘要： The present disclosure provides a method for transmitting a synchronization signal (SS), the method comprising: performing a listen-before-talk (LBT) operation in a pre-defined window; if the LBT operation succeeds, transmitting an SS block (SSB) in the window, wherein the SSB comprises the SS, or the SSB comprises the SS and a physical broadcast channel (PBCH). Compared with the prior art, the present disclosure may significantly improve the efficiency of data transmission and the access performance for the communication system by relaxing the time when the base station implements the LBT, that is, allowing the base station to implement the LBT in the pre-defined window and transmit the SSB after the LBT succeeds.
