Abstract
A method for transmitting and receiving control information between AM RLC entities in a mobile communication system is provided. Especially, when a receiving-side AM RLC entity is connected to one or more logical channels, the receiving-side AM RLC entity sends control information through a specific one of the logical channels according to the contents of the control information to allow the transmitting side to quickly perform retransmission, thereby increasing the data transmitting rate.
Claims16
An apparatus for transmitting Protocol Data Unit (PDU) in a mobile communication system, the apparatus comprising:
- a Radio Link Control (RLC) entity in acknowledged mode, the RLC entity receiving data from an upper layer and generating a data PDU and one or more control PDUs;
- and
- a Medium Access Control (MAC) entity connected with the RLC entity via a first logical channel and a second logical channel,
- wherein the data PDU and a first control PDU are transmitted via the first logical channel, and a second control PDU is transmitted via the second logical channel,
- wherein the first control PDU includes a Reset PDU, a Reset ACK PDU and a piggybacked status PDU,
- wherein the second control PDU includes a status PDU containing acknowledgement information.
A method of transmitting protocol data unit (PDU) at a Radio Link Control (RLC) entity in acknowledged mode (AM), wherein the RLC entity in AM is configured in an apparatus used for a mobile communication system, the method comprising:
- receiving data from an upper layer;
- generating at least one of a data PDU and one or more control PDUs;
- and
- transmitting at least one of a data PDU and one or more control PDUs to a Medium Access Control (MAC) entity via a first channel and a second channel,
- wherein the data PDU and a first control PDU are transmitted via the first logical channel, and a second control PDU is transmitted via the second control channel,
- wherein the first control PDU includes a Reset PDU, a Reset ACK PDU and a piggybacked status PDU,
- wherein the second control PDU includes a status PDU containing acknowledgement information.
