Abstract
The present disclosure relates to a fifth generation (5G) or pre-5G communication system to be provided to support a higher data transmission rate since fourth generation (4G) communication systems like long-term evolution (LTE). A method of a receiver in a wireless communication system is provide. The method includes receiving at least one packet, identifying whether there is a non-received packet among the at least one packet, and transmitting status report information when there is the non-received packet, in which the status report information includes a field indicating whether there are consecutively non-received packets.
Claims12
A method performed by a transmitter in a communication system, the method comprising:
- obtaining a radio link control (RLC) service data unit (SDU);
- identifying an RLC protocol data unit (PDU) including a header, the header including 2 bits information associated with segmentation indicating whether the RLC PDU includes a complete RLC SDU, a first segment of the RLC SDU, a middle segment of the RLC SDU, or a last segment of the RLC SDU;
- and
- transmitting the RLC PDU including the header,
- wherein the header includes segment offset information indicating a position of a segmented RLC SDU in case that the 2 bits information associated with segmentation indicates that the RLC PDU includes the segmented RLC SDU that is the middle segment of the RLC SDU or the last segment of the RLC SDU.
A method performed by a receiver in a communication system, the method comprising:
- receiving a radio link control (RLC) protocol data unit (PDU) including a header;
- identifying whether the RLC PDU includes a complete RLC service data unit (SDU) based on 2 bits information associated with segmentation included in the header, the 2 bits information associated with segmentation indicating whether the RLC PDU includes the complete RLC SDU, a first segment of an RLC SDU, a middle segment of the RLC SDU, or a last segment of the RLC SDU;
- and
- identifying the RLC SDU based on a result of the identification,
- wherein the header includes segment offset information indicating a position of a segmented RLC SDU in case that the 2 bits information associated with segmentation indicates that the RLC PDU includes the segmented RLC SDU that is the middle segment of the RLC SDU or the last segment of the RLC SDU.
A transmitter in a communication system, the transmitter comprising:
- a transceiver;
- and
- at least one processor coupled with the transceiver and configured to:
- obtain a radio link control (RLC) service data unit (SDU),
- identify an RLC protocol data unit (PDU) including a header, the header including 2 bits information associated with segmentation indicating whether the RLC PDU includes a complete RLC SDU, a first segment of the RLC SDU, a middle segment of the RLC SDU, or a last segment of the RLC SDU, and
- transmit the RLC PDU including the header,
- wherein the header includes segment offset information indicating a position of a segmented RLC SDU in case that the 2 bits information associated with segmentation indicates that the RLC PDU includes the segmented RLC SDU that is the middle segment of the RLC SDU or the last segment of the RLC SDU.
A receiver in a communication system, the receiver comprising:
- a transceiver;
- and
- at least one processor coupled with the transceiver and configured to:
- receive a radio link control (RLC) protocol data unit (PDU) including a header,
- identify whether the RLC PDU includes a complete RLC service data unit (SDU) based on 2 bits information associated with segmentation included in the header, the 2 bits information field associated with segmentation indicating whether the RLC PDU includes the complete RLC SDU, a first segment of an RLC SDU, a middle segment of the RLC SDU, or a last segment of the RLC SDU, and
- identify the RLC SDU based on a result of the identification,
- wherein the header includes segment offset information indicating a position of a segmented RLC SDU in case that the 2 bits information associated with segmentation indicates that the RLC PDU includes the segmented RLC SDU that is the middle segment of the RLC SDU or the last segment of the RLC SDU.
