Abstract

A method for processing, by a user equipment (UE), data suspended in a new radio (NR) branch of a separate bearer is disclosed. The method includes predicting an occurrence of an NR uplink (UL) branch handover; transmitting a buffer status report (BSR) related to a protocol data unit (PDU) in a radio link control (RLC) layer and a media access control (MAC) layer in the NR branch based on the predicted occurrence of the NR UL branch handover; and initiating recovery of the suspended PDU in the NR branch after the NR UL branch handover occurs, where the recovery includes transmitting the suspended PDU to a long term evolution (LTE) branch of a separate bearer.

Description

technical field [0001] Embodiments herein relate to uplink (UL) leg switching in a split bearer network, and more particularly, to a method for implementing a transition to long-term evolution (LTE) UL leg or new radio ( Method and system for recovery of data in NR) UL legs. Background technique [0002] In split bearer networks, there is the possibility that uplink (UL) branch switching can be triggered by the network to switch UL transmissions by user equipment (UE). The network may trigger UL branch switching of Long Term Evolution (LTE) UL branch or New Radio (NR) UL branch. When UL branch switching is triggered, the network may stop or resume the allocation of UL grants on either of the UL branches (LTE or NR) if the UL data sent by the UE exceeds the ul-DataSplitThreshold configured by the network. For example, if the network intends to trigger a UL branch handover from NR to LTE due to poor channel conditions in the NR channel, and if the amount of UL data sent has ...
