Method for transmitting and receiving uplink control information and devices supporting the same

Abstract

Disclosed herein are a method for transmitting and receiving uplink control information between a terminal and a base station in a wireless communication system and devices supporting the same. Particularly, disclosed herein are a method for transmitting and receiving uplink control information between a terminal and a base station on a physical uplink shared channel (PUSCH) without data (e.g., UL-SCH) and operation of devices supporting the same.

What is claimed is: 
     
         1 . A method of transmitting an uplink control information (UCI) by a user equipment (UE) in a wireless communication system, the method comprising:
 multiplexing the UCI in a physical uplink shared channel (PUSCH) among a plurality of PUSCHs including one or more first PUSCHs scheduled by downlink control information (DCI) for scheduling an uplink transmission and one or more second PUSCHs configured without a dynamic uplink grant,   wherein resources for the plurality of PUSCHs overlap with resources for a physical uplink control channel (PUCCH) scheduled for transmitting the UCI; and   transmitting the UCI,   wherein the PUSCH in which the UCI is multiplexed is one of the first PUSCHs.   
     
     
         2 . The method of  claim 1 ,
 wherein the PUSCH in which the UCI is multiplexed is a PUSCH to be transmitted first among the one or more first PUSCHs.   
     
     
         3 . The method of  claim 1 ,
 wherein the resources for the plurality of PUSCHs overlap with the resources for a physical uplink control channel (PUCCH) scheduled for transmitting the UCI on a time domain.   
     
     
         4 . The method of  claim 1 ,
 wherein the one or more second PUSCHs is configured based on semi-persistent scheduling (SPS).   
     
     
         5 . A user equipment (UE) configured for transmitting an uplink control information (UCI) in a wireless communication system, the UE comprising:
 at least one transceiver;   at least one processor; and   at least one computer memory operably coupled to the at least one processor and storing instructions that, when executed by the at least one processor, control the UE to perform operations comprising:   multiplexing the UCI in a physical uplink shared channel (PUSCH) among a plurality of PUSCHs including one or more first PUSCHs scheduled by downlink control information (DCI) for scheduling an uplink transmission and one or more second PUSCHs configured without a dynamic uplink grant,   wherein resources for the plurality of PUSCHs overlap with resources for a physical uplink control channel (PUCCH) scheduled for transmitting the UCI; and   transmitting the UCI,   wherein the PUSCH in which the UCI is multiplexed is one of the first PUSCHs.   
     
     
         6 . The UE of  claim 5 ,
 wherein the PUSCH in which the UCI is multiplexed is a PUSCH to be transmitted first among the one or more first PUSCHs.   
     
     
         7 . The UE of  claim 5 ,
 wherein the resources for the plurality of PUSCHs overlap with the resources for a physical uplink control channel (PUCCH) scheduled for transmitting the UCI on a time domain.   
     
     
         8 . The UE of  claim 5 ,
 wherein the one or more second PUSCHs is configured based on semi-persistent scheduling (SPS).   
     
     
         9 . A base station (BS) configured for receiving an uplink control information (UCI) in a wireless communication system, the BS comprising:
 at least one transceiver;   at least one processor; and   at least one computer memory operably coupled to the at least one processor and storing instructions that, when executed by the at least one processor, control the BS to perform operations comprising:   receiving, from a user equipment (UE), the UCI,   wherein the UCI is multiplexed in a physical uplink shared channel (PUSCH) among a plurality of PUSCHs including one or more first PUSCHs scheduled by a downlink control information (DCI) for scheduling an uplink transmission and one or more second PUSCHs configured without a dynamic uplink grant,   wherein resources for the plurality of PUSCHs overlap with resources for a physical uplink control channel (PUCCH) scheduled for transmitting the UCI, and   wherein the PUSCH in which the UCI is multiplexed is one of the first PUSCHs.   
     
     
         10 . The BS of  claim 9 ,
 wherein the PUSCH in which the UCI is multiplexed is a PUSCH to be transmitted first among the one or more first PUSCHs.   
     
     
         11 . The BS of  claim 9 ,
 wherein the resources for the plurality of PUSCHs overlap with the resources for a physical uplink control channel (PUCCH) scheduled for transmitting the UCI on a time domain.   
     
     
         12 . The BS of  claim 9 ,
 wherein the one or more second PUSCHs is configured based on semi-persistent scheduling (SPS).
