UPLINK RECONFIGURATION FOR SPLIT BEARER IN DUAL CONNECTIVITY

摘要

According to some embodiments, a wireless device operating in dual connectivity with a first and second network node performs a method comprising establishing an uplink radio connection from the wireless device to the first and second network nodes. The wireless device comprises first MAC and RLC modules for uplink radio communication with the first network node, second MAC and RLC modules for uplink radio communication with the second network node, and a PDCP module for communicating with the first and second RLC modules. The method further comprises communicating data for uplink transmission from the PDCP module to the first RLC module; obtaining an indication to switch transmission of uplink data from the first network node to the second network node; resetting the first RLC module and the first MAC module; and communicating data for uplink transmission from the PDCP module to the second RLC module.
