Abstract
Embodiments of this application disclose a data processing method and device. The method includes: receiving, through a first bearer between a MAC layer and a user-plane functional entity of layer 3, a MAC SDU sent by the user-plane functional entity of layer 3 and a sequence number assigned to the MAC SDU, wherein all MAC SDUs sent by the first bearer last time correspond to the same sequence number; and generating a MAC PDU according to the received MAC SDU and the sequence number corresponding to the MAC SDU and sending it to a physical layer. The MAC PDU comprises at least one of: an ID of the first bearer, the sequence number, and at least one MAC SDU corresponding to the sequence number.

A data processing method, comprising:
- receiving, through a first bearer between a medium access control (MAC) layer and a user-plane functional entity of layer 3, one or more medium access control service data units (MAC SDUs) sent by the user-plane functional entity of layer 3 and one or more sequence numbers assigned to the one or more MAC SDUs, wherein all MAC SDUs sent on the first bearer use the same sequence number;
- and
- generating a medium access control protocol data unit (MAC PDU) according to the one or more received MAC SDUs and the one or more sequence numbers corresponding to the one or more MAC SDUs and sending the MAC PDU to a physical layer, wherein the MAC PDU comprises at least one of the following:
- an identification (ID) of the first bearer, the one or more sequence numbers, and at least one MAC SDU corresponding to the one or more sequence numbers.
A data processing method, comprising:
- receiving a MAC PDU from a physical layer, wherein the MAC PDU comprises at least one of the following:
- an ID of a first bearer, one or more MAC SDUs, and one or more sequence numbers corresponding to the one or more MAC SDUs;
- the same sequence number corresponds to at least one MAC SDU, and the first bearer is a bearer for transmitting the at least one MAC SDU between a MAC layer and a user-plane functional entity of layer 3;
- parsing the MAC PDU to obtain the ID of the first bearer and all the MAC SDUs corresponding to the same sequence number, wherein all MAC SDUs sent on the first bearer use the same sequence number;
- and
- sending the at least one MAC SDU corresponding to the same sequence number to the user-plane functional entity of layer 3 through the first bearer according to ordering of the at least one MAC SDU in the MAC PDU.
A first device, comprising:
- a processor, a memory, and a program that is stored on the memory and executable on the processor, wherein the program, when executed by the processor, causes the processor to:
- receive, through a first bearer between a medium access control (MAC) layer and a user-plane functional entity of layer 3, one or more medium access control service data units (MAC SDUs) sent by the user-plane functional entity of layer 3 and one or more sequence numbers assigned to the one or more MAC SDUs, wherein all MAC SDUs sent on the first bearer use the same sequence number;
- and
- generating a medium access control protocol data unit (MAC PDU) according to the one or more received MAC SDUs and the one or more sequence numbers corresponding to the one or more MAC SDUs and sending the MAC PDU to a physical layer, wherein the MAC PDU comprises at least one of the following:
- an identification (ID) of the first bearer, the one or more sequence numbers, and at least one MAC SDU corresponding to the one or more sequence numbers.
