Abstract
A method of transmitting and receiving Automatic Repeat reQuest (ARQ) feedback information in a wireless communication system is disclosed. The method of transmitting ARQ feedback information in a wireless communication system includes, at a transmitter, transmitting a Protocol Data Unit (PDU) including an extended header including an ARQ feedback Polling Request (APR) field indicating whether or not the transmitter makes a request for ARQ feedback polling, and receiving an Acknowledgement (ACK) from a receiver if the APR field indicates that the transmitter makes the request for ARQ feedback polling to the receiver.
Claims19
A method of receiving an Automatic Repeat Request (ARQ) feedback at a transmitter in wireless communication system, the method comprising:
- transmitting a Protocol Data Unit (PDU) including an extended header that includes an ARQ feedback Polling (AFP) field or a Type field indicating whether or not the transmitter makes a request for ARQ feedback polling to a receiver;
- and
- receiving the ARQ feedback from the receiver when the AFP field or the Type field indicates that the transmitter makes the request for ARQ feedback polling.
A method of transmitting an Automatic Repeat Request (ARQ) feedback at a receiver in a wireless communication system, the method comprising:
- receiving a Protocol Data Unit (PDU) including an extended header that includes an ARQ Feedback Polling (AFP) field or a Type field indicating whether or not a transmitter makes a request for ARQ feedback polling from the transmitter;
- and
- transmitting the ARQ feedback to the transmitter when the AFP field or the Type field indicates that the transmitter makes the request for ARQ feedback polling.
A method of transmitting Automatic Repeat Request (ARQ) feedback information at a transmitter in a wireless communication system, the method comprising:
- generating a Protocol Data Unit (PDU) including a Multiplexing Extended Header (MEH) including an ARQ Feedback Information Element (IE) Indication (AFI) field and Multiplexing Extended Header Blocks (MEHBs);
- and
- transmitting the generated PDU to a receiver,
- wherein the AFI field indicates whether or not the PDU includes an ARQ feedback IE, and
- wherein each of the MEHBs includes information about Service Data Units (SDUs) or SDU fragments included in the same connection.
A method of receiving an Automatic Repeat Request (ARQ) feedback at a transmitter in a wireless communication system, the method comprising:
- transmitting a Protocol Data Unit (PDU) including an extended header including a Type field indicating whether or not the transmitter makes a request for ARQ feedback polling to a receiver;
- and
- receiving the ARQ feedback from the receiver if the Type field indicates that the transmitter makes the request for ARQ feedback.
A method of transmitting an Automatic Repeat Request (ARQ) feedback at a receiver in a wireless communication system, the method comprising:
- receiving an ARQ feedback poll for requesting ARQ feedback polling from a transmitter;
- and
- transmitting to the transmitter a Protocol Data Unit (PDU) including an extended header including a Type field indicating whether or not the ARQ feedback is transmitted in response to the ARQ feedback polling request.
