Abstract
Disclosed are a data transmission method and a related product. The method includes: when it is detected that a data replication transmission function of a PDCP layer entity is activated, a terminal enabling a first RLC layer entity, a second RLC layer entity being in an enabled status; and invoking the PDCP layer entity to determine a first PDCP PDU associated with a first PDCP SDU, and sending the first PDCP PDU to the first RLC layer entity, wherein the first PDCP PDU is used for the first RLC layer entity and a MAC layer entity to process the first PDCP PDU into a MAC PDU and send same.
Claims12
A data transmission method, applied to a terminal comprising a PDCP layer entity, a first RLC layer entity, and a second RCL layer entity, wherein the method comprises:
- receiving, by the PDCP layer entity, a second PDCP SDU;
- when a data duplication transmission function of the PDCP layer entity is activated,
- encapsulating, by the PDCP layer entity, the second PDCP SDU into a second PDCP PDU, and,
- sending, by the PDCP layer entity, the second PDCP PDU to the first RLC layer entity and the second RLC layer entity.
A terminal, comprising a processor, a memory, a communication interface, and one or more programs stored in the memory and configured to be executed by a processor, wherein the programs comprise instructions to:
- receive a second PDCP SDU via a PDCP layer entity;
- when a data duplication transmission function of a PDCP layer entity is activated, encapsulate a second PDCP SDU into a second PDCP PDU via the PDCP layer entity;
- and
- send the second PDCP PDU to a first RLC layer entity and a second RLC layer entity via the PDCP layer entity.
A network side device, comprising a processor, a memory, a communication interface, and one or more programs stored in the memory and configured to be executed by a processor, wherein the programs comprise instructions to:
- acquire an MAC PDU of a terminal, wherein the MAC PDU is obtained through processing a first PDCP PDU by a first RLC layer entity and a MAC layer entity, the first PDCP PDU is associated with a first PDCP SDU and determined by the terminal through enabling the first RLC layer entity and invoking a PDCP layer entity when detecting that a data duplication transmission function of the PDCP layer entity is activated, and the first PDCP PDU is sent by the terminal to the first RLC layer entity, a second RLC layer entity being in an enabled status.
