Radio link control transmission method and related products

A method for radio link control (RLC) transmission, comprising:

• sending a first RLC protocol data unit (PDU) set to a receiving-side RLC entity, wherein the first RLC PDU set is generated according to a raw data segment;
• receiving a status report containing an indication domain for sequence numbers (SNs) of multiple RLC PDUs from the receiving-side RLC entity, wherein the status report is sent by the receiving-side RLC entity responsive to detecting that the multiple RLC PDUs in the first RLC PDU set are not successfully received;
• and
• sending a second RLC PDU set to the receiving-side RLC entity, wherein the first RLC PDU set and the second RLC PDU set are used to acquire the raw data segment.

A user equipment (UE), comprising a processor and a communication interface, wherein

• the processor is configured to:
• receive, through the communication interface, a first RLC protocol data unit (PDU) set from a sending-side RLC entity in a base station, wherein the first RLC PDU set is generated by the sending-side RLC entity according to a raw data segment,
• responsive to detecting that multiple RLC PDUs in the first RLC PDU set are not successfully received, send, through the communication interface, a status report containing an indication domain for sequence numbers (SNs) of the multiple RLC PDUs,
• receive, through the communication interface, a second RLC PDU set from the sending-side RLC entity, and
• acquire the raw data segment according to the first RLC PDU set and the second RLC PDU set.

A base station, comprising a processor and a radio frequency (RF) chip, wherein

• the processor is configured to:
• send, through the RF chip, a first RLC protocol data unit (PDU) set to a receiving-side RLC entity in a user equipment (UE), wherein the first RLC PDU set is generated according to a raw data segment,
• receive, through the RF chip, a status report containing an indication domain for sequence numbers (SNs) of multiple RLC PDUs from the receiving-side RLC entity, wherein the status report is sent by the receiving-side RLC entity responsive to detecting that the multiple RLC PDUs in the first RLC PDU set are not successfully received, and
• send, through the RF chip, a second RLC PDU set to the receiving-side RLC entity, wherein the first RLC PDU set and the second RLC PDU set are used to acquire the raw data segment.
