TECHNIQUES FOR TRANSMITTING UPLINK DATA AFTER AN UPLINK PATH SWITCH

摘要

Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may have a dual-connectivity functionality and may establish a first connection with a first cell and a second connection with a second cell. In some examples, the UE may determine to switch from communicating with the first cell to communicating with the second cell while the UE has uplink data queued for transmission to the first cell and may determine to transmit the uplink data to the second cell for tunneling to the first cell based on a tunneling configuration. The UE may transit the uplink data to the second cell along with a tunneling indicator that indicates that the uplink data is to be tunneled to the first cell. Accordingly, the second cell my tunnel the uplink data from an entity of the second cell to an entity of the first cell.
