Abstract
A method and apparatus for reconstruction of a protocol data unit (PDU) for fast and reliable retransmission of a service data unit (SDU) after maximum retransmission is provided. Upon determining that a hybrid automatic repeat request (HARQ) retransmission of a first PDU including a specific SDU is unsuccessful, a wireless device constructs a second PDU including the first SDU which is prioritized to be included in the second PDU.
Claims15
A method for a wireless device in a wireless communication system, the method comprising:
- performing transmission of a first protocol data unit (PDU) including a first service data unit (SDU), wherein the first SDU is associated with a particular logical channel;
- determining that a hybrid automatic repeat request (HARQ) retransmission of the first PDU is unsuccessful;
- constructing a second PDU including the first SDU based on a determination that the HARQ retransmission of the first PDU is unsuccessful, wherein the first SDU is prioritized to be included in the second PDU;
- and
- performing transmission of the second PDU including the first SDU.
2 more elements
A wireless device in a wireless communication system, comprising:
- at least one transceiver;
- at least processor;
- and
- at least one computer memory operably connectable to the at least one processor and storing instructions that, based on being executed by the at least one processor, perform operations comprising:
- performing transmission of a first protocol data unit (PDU) including a first service data unit (SDU), wherein the first SDU is associated with a particular logical channel;
- determining that a hybrid automatic repeat request (HARQ) retransmission of the first PDU is unsuccessful;
- constructing a second PDU including the first SDU based on a determination that the HARQ retransmission of the first PDU is unsuccessful, wherein the first SDU is prioritized to be included in the second PDU;
- and
- performing transmission of the second PDU including the first SDU.
