Abstract

A method by a wireless communication network for handling one or more duplicated packet data convergence protocol (PDCP) packets is described. The method includes sending, by a master node, a request for a configuration for duplication to a secondary node, and providing, by a secondary node, a mapping configuration for duplication in a secondary cell group (SCG) to a user equipment (UE).

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A method by a wireless communication network for handling one or more duplicated packet data convergence protocol (PDCP) packets, the method comprising:
 sending, by a master node, a request for a configuration for duplication to a secondary node;   providing, by a secondary node, a mapping configuration for duplication in a secondary cell group (SCG) to a user equipment (UE).   
     
     
         2 . The method of  claim 1 , further comprising:
 configuring, by the secondary node, one or more allowed serving cells in the SCG for receiving the one or more duplicated PDCP packets, the one or more allowed serving cells including at least one of a primary secondary cell (PSCell) and one or more secondary cells (SCells) of the secondary node.   
     
     
         3 . The method of  claim 2 , wherein the mapping configuration provides mapping rules between one or more logical channels and the one or more allowed serving cells. 
     
     
         4 . The method of  claim 2 , wherein the mapping configuration provides one or more Serving Cell indices corresponding to the one or more allowed serving cells for receiving the one or more duplicated PDCP packets. 
     
     
         5 . The method of  claim 4 , wherein a Serving Cell index value=0 is mapped to the PSCell in the SCG corresponding to at least one logical channel through which the UE is allowed to deliver the one or more duplicated PDCP packets. 
     
     
         6 . The method of  claim 1 , wherein:
 the mapping configuration for duplication in the SCG includes information of at least one physical radio resource block on one or more allowed serving cells for receiving the one or more duplicated PDCP packets from the UE.   
     
     
         7 . The method of  claim 1 , further comprising:
 sending, by the secondary node, an activation message of packet duplication to the UE to activate at least one logical channel corresponding to at least one radio bearer for the UE to deliver the one or more duplicated PDCP packets.   
     
     
         8 . The method of  claim 7 , further comprising:
 receiving, by the secondary node, the one or more duplicated PDCP packets in the at least one logical channel corresponding to the at least one radio bearer for the UE.   
     
     
         9 . The method of  claim 7 , further comprising:
 sending, by the secondary node, a deactivation message of packet duplication to the UE to stop the UE from applying one or more allowed serving cells in the SCG to the at least one logical channel.   
     
     
         10 . The method of  claim 1 , further comprising:
 providing, by the master node, a mapping configuration for duplication in a master cell group (MCG) to the UE.   
     
     
         11 . The method of  claim 10 , further comprising:
 configuring, by the master node, one or more allowed serving cells in the MCG for receiving the one or more duplicated PDCP packets, the one or more allowed serving cells including at least one of a primary cell (PCell) and one or more secondary cells (S Cells) of the master node.   
     
     
         12 . The method of  claim 10 , wherein the mapping configuration provides mapping rules between one or more logical channels and the one or more allowed serving cells. 
     
     
         13 . The method of  claim 10 , wherein the mapping configuration provides one or more Serving Cell indices corresponding to the one or more allowed serving cells for receiving the one or more duplicated PDCP packets. 
     
     
         14 . The method of  claim 13 , wherein a Serving Cell index value=0 is mapped to the PCell in the MCG corresponding to at least one logical channel through which the UE is allowed to deliver the one or more duplicated PDCP packets. 
     
     
         15 . The method of  claim 10 , wherein:
 the mapping configuration for duplication in the MCG includes information of at least one physical radio resource block on one or more allowed serving cells for receiving the one or more duplicated PDCP packets from the UE.   
     
     
         16 . The method of  claim 10 , further comprising:
 sending, by the master node, an activation message of packet duplication to the UE to activate at least one logical channel corresponding to at least one radio bearer for the UE to deliver the one or more duplicated PDCP packets.   
     
     
         17 . The method of  claim 16 , further comprising:
 receiving, by the master node, the one or more duplicated PDCP packets in the at least one logical channel corresponding to the at least one radio bearer for the UE.   
     
     
         18 . The method of  claim 16 , further comprising:
 sending, by the master node, a deactivation message of packet duplication to the UE to stop the UE from applying one or more allowed serving cells in the MCG to the at least one logical channel.
