Abstract
In accordance with example embodiments as described herein there is at least an apparatus and method to perform transmitting packet data convergence protocol data unit duplicates over two or more carriers; receiving an indication that indicates packet data convergence protocol data unit has been correctly transmitted via one of two or more carriers; and upon receiving the indication, instructing to discard other packet data convergence protocol duplicates over carriers other than the one of two or more carriers with a successful delivery.
Claims15
A mobile device comprising:
- at least one processor;
- and
- at least one memory storing instructions thereon that, when executed by the at least one processor, cause the mobile device to perform at least:
- instructing to transmit, over two or more carriers, a packet data convergence protocol (PDCP) protocol data unit (PDU) and a PDCP PDU duplicate, wherein the PDCP PDU and the PDCP PDU duplicate are used for uplink transmissions by the mobile device;
- receiving an indication, from a radio link control (RLC) entity, that one of the PDCP PDU or the PDCP PDU duplicate has been successfully delivered via one of the two or more carriers as confirmed by the RLC entity;
- and
- in response to receiving the indication, instructing to discard the other one of the PDCP PDU or the PDCP PDU duplicate over at least one carrier other than the one of two or more carriers with successful delivery as confirmed by the RLC entity.
A method comprising:
- instructing, by a mobile device, to transmit a packet data convergence protocol (PDCP) protocol data unit (PDU) and a PDCP PDU duplicate for uplink transmissions over two or more carriers;
- receiving an indication, from a radio link control (RLC) entity, that one of the PDCP PDU or the PDCP PDU duplicate has been successfully delivered via one of the two or more carriers as confirmed by the RLC entity;
- and
- in response to receiving the indication, instructing to discard the other one of the PDCP PDU or the PDCP PDU duplicate over at least one carrier other than the one of two or more carriers with successful delivery as confirmed by the RLC entity.
A non-transitory computer-readable storage medium comprising instructions thereon that, when executed by at least one processor, cause a mobile device to perform at least:
- instructing to transmit, over two or more carriers, a packet data convergence protocol (PDCP) protocol data unit (PDU) and a PDCP PDU duplicate;
- receiving an indication, from a radio link control (RLC) entity, that one of the PDCP PDU or the PDCP PDU duplicate has been successfully delivered via one of the two or more carriers as confirmed by the RLC entity;
- and
- in response to receiving the indication, instructing to discard the other one of the PDCP PDU or the PDCP PDU duplicate over at least one carrier other than the one of two or more carriers with successful delivery as confirmed by the RLC entity.
