Abstract
Methods and apparatus are provided for communication between a User Equipment (UE) and a Node B in a communication system. The UE generates a Media Access Control-Protocol Data Unit (MAC-PDU) including scheduling information having information representing an amount of packet data to be transmitted. The MAC-PDU including the scheduling information is transmitted to the Node B. The information representing the amount of packet data exists per priority queue.
Claims32
A method for communication between a User Equipment (UE) and a Node B in a communication system, the method comprising the steps of:
- generating, by the UE, a Media Access Control-Protocol Data Unit (MAC-PDU) comprising a first field related to at least one queue ID and a second field related to at least one amount of data to be transmitted, where the data to be transmitted has its priority;
- and
- transmitting the MAC-PDU comprising the first and second fields to the Node B;
- receiving grant information from the Node B;
- and
- transmitting data to the Node B based on the grant information and the priority,
- wherein one amount of data in the second field corresponds to one queue ID in the first field.
An apparatus for communication between a User Equipment (UE) and a Node B in a communication system, the apparatus comprising:
- a data unit generator for generating a Media Access Control-Protocol Data Unit (MAC-PDU) comprising a first field related to at least one queue ID and a second field related to at least one amount of data to be transmitted, where the data to be transmitted has its priority;
- and
- a transmission unit for transmitting the MAC-PDU comprising the first and second fields to the Node B, and transmitting data to the Node B based on grant information received from the Node B and the priority,
- wherein one amount of data in the second field corresponds to one queue ID in the first field.
A method for communication between a User Equipment (UE) and Node B in a communication system, the method comprising the steps of:
- receiving, by the Node B, a Media Access Control-Protocol Data Unit (MAC-PDU) comprising a first field related to at least one queue ID and a second field related to at least one amount of data to be transmitted, where the data to be transmitted has its priority;
- scheduling an uplink packet data service of the UE;
- transmitting grant information to the UE according to the scheduling,
- receiving data transmitted from the UE based on the grant information and the priority.
- wherein one amount of data in the second field corresponds to one queue ID in the first field.
An apparatus for communication between a User Equipment (UE) and a Node B in a communication system, the apparatus comprising:
- a reception unit for receiving a Media Access Control-Protocol Data Unit (MAC-PDU) comprising a first field related to at least one queue ID and a second field related to at least one amount of data to be transmitted, where the data to be transmitted has its priority;
- a scheduler for scheduling an uplink packet data service of the UE;
- and
- a transmission unit for transmitting grant information to the UE according to the scheduling,
- wherein the reception unit receives data transmitted from the UE based on the grant information and the priority, and
- wherein one amount of data in the second field corresponds to one queue ID in the first field.
