Patent ID: 11343169

Abstract:
For duplicating PDCP PDUs for a radio bearer, methods, apparatus, and systems are disclosed. One apparatus includes a processor and a transceiver for communicating with a network. The processor establishes a radio bearer to communicate with the network, the radio bearer including a PDCP entity, first and second RLC entities associated with said PDCP entity, and first and second logical channels associated with said first and second RLC entities, respectively. The processor receives a control signal from the network and submits a PDCP data PDU in the PDCP entity to the first RLC entity for transmission. In response to the first control signal, the processor submits the PDCP data PDU to the second RLC entity for transmission. The processor indicates to one of the first and second RLC entities to discard a duplicate PDCP data PDU corresponding to a successfully delivered PDCP data PDU.
