Method and user equipment device for transmitting uplink data

Abstract

A user equipment (UE) may be configured with multiple logical channels (LoCHs). The multiple LoCHs may include at least one LoCH (U-LoCH) allowed to be transmitted via a unlicensed band. If the UE receives a uplink grant for a licensed band, the UE disables a priority bit rate of the U-LoCH for the uplink grant when applying a logical channel prioritization procedure.

What is claimed is: 
     
         1 . A method for transmitting, by a user equipment (UE), uplink (UL) data, the method comprising:
 receiving configuration information related to multiple logical channels (LoCHs), wherein the configuration information includes multiple priority bit rates (PBRs) for at least one of the multiple LoCHs;   receiving an UL grant related to one of the multiple PBRs;   generating the UL data based on the UL grant by performing a logical channel prioritization (LCP) for the multiple LoCHs; and   transmitting the UL data to a network.   
     
     
         2 . The method according to  claim 1 , wherein generating the UL data comprises:
 based on the UL grant being related to a licensed band, performing the LCP based on a PBR for the licensed band among the multiple PBRs, and   based on the UL grant being related to an unlicensed band, performing the LCP based on a PBR for the unlicensed band among the multiple PBRs.   
     
     
         3 . The method according to  claim 1 , wherein generating the UL data comprises:
 based on the UL grant being related to a licensed band, performing the LCP based on disabling a PBR for a LoCH (U-LoCH) allowed to be transmitted via an unlicensed band, and   based on the UL grant being related to the unlicensed band, performing the LCP based on not disabling the PBR for the U-LoCH.   
     
     
         4 . The method according to  claim 3 , wherein disabling the PBR for the U-LoCH comprises:
 setting the PBR for the U-LoCH to zero.   
     
     
         5 . The method according to  claim 1 , wherein performing the LCP comprises:
 allocating UL resources of the UL grant to at least one LoCH of the multiple LoCHs according to respective PBRs for the multiple LoCHs.   
     
     
         6 . The method according to  claim 1 , wherein the configuration information further includes multiple priority values for at least one the multiple LoCHs, and
 wherein the UL grant is related to one of the multiple priority values.   
     
     
         7 . The method according to  claim 6 , wherein performing the LCP comprises:
 allocating UL resources of the UL grant to at least one LoCH of the multiple LoCHs according to respective PBRs and priority values for the multiple LoCHs.   
     
     
         8 . The method according to  claim 1 ,
 wherein the configuration information further informs whether data of each of the multiple LoCHs is allowed to be transmitted via an unlicensed band or not.   
     
     
         9 . The method according to  claim 1 ,
 wherein the configuration information further informs whether each PBR among the multiple PBRs is for transmitting data via an unlicensed band or a licensed band.   
     
     
         10 . A user equipment (UE) for transmitting uplink (UL) data, the UE comprising:
 a transceiver, and   a processor that:   receives configuration information related to multiple logical channels (LoCHs), wherein the configuration information includes multiple priority bit rates (PBRs) for at least one of the multiple LoCHs,   receives an UL grant related to one of the multiple PBRs,   generates the UL data based on the UL grant by performing a logical channel prioritization (LCP) for the multiple LoCHs, and   transmits the UL data to a network.   
     
     
         11 . The UE according to  claim 10 , wherein the processor generates the UL data by:
 based on the UL grant being related to a licensed band, performing the LCP based on a PBR for the licensed band among the multiple PBRs, and   based on the UL grant being related to an unlicensed band, performing the LCP based on a PBR for the unlicensed band among the multiple PBRs.   
     
     
         12 . The UE according to  claim 10 , wherein the processor generates the UL data by:
 based on the UL grant being related to a licensed band, performing the LCP based on disabling a PBR for a LoCH (U-LoCH) allowed to be transmitted via an unlicensed band, and   based on the UL grant being related to the unlicensed band, performing the LCP based on not disabling the PBR for the U-LoCH.   
     
     
         13 . The UE according to  claim 12 , wherein the processor disables the PBR for the U-LoCH by setting the PBR for the U-LoCH to zero. 
     
     
         14 . The UE according to  claim 10 , wherein the processor performs the LCP by allocating UL resources of the UL grant to at least one LoCH of the multiple LoCHs according to respective PBRs for the multiple LoCHs. 
     
     
         15 . The UE according to  claim 10 , wherein the configuration information further includes multiple priority values for at least one the multiple LoCHs, and wherein the UL grant is related to one of the multiple priority values. 
     
     
         16 . The UE according to  claim 15 , wherein the processor performs the LCP by allocating UL resources of the UL grant to at least one LoCH of the multiple LoCHs according to respective PBRs and priority values for the multiple LoCHs. 
     
     
         17 . The UE according to  claim 10 ,
