Abstract

A communication system, a mobile station device, a base station device, and a processing method for carrying out processing involved in introducing a contention based uplink efficiently, and carrying out communication promptly, are provided. A mobile station device communicating with a base station device in a mobile communication system includes a buffer for a contention based uplink and a buffer for a regular uplink HARQ, as a buffer for a HARQ.

Claims

1. A mobile station device communicating with a base station device in a mobile communication system, said mobile station device adapted to obtain a CB-RNTI identifying a contention based uplink from broadcasted system information, and obtain presence/absence of a usage grant of the contention based uplink through RRC signaling of a dedicated signal.

2. A mobile station device communicating with a base station device in a mobile communication system, said mobile station device comprising:

a buffer for a contention based uplink and a buffer for a regular uplink HARQ, as a buffer for a HARQ.

3. A mobile station device communicating with a base station device in a mobile communication system, said mobile station device adapted to

obtain a maximum number of times of retransmission of a HARQ for a contention based uplink and a maximum number of times of retransmission of a HARQ for a regular uplink from the base station device, and

carry out HARQ processing according to each of said maximum number of times of retransmission.

4. A processing method at a mobile station device communicating with a base station device in a mobile communication system, comprising the steps of:

obtaining a CB-RNTI identifying a contention based uplink from broadcasted system information, and obtaining presence/absence of a usage grant of the contention based uplink through RRC signaling of a dedicated signal.

5. A processing method at a mobile station device communicating with a base station device in a mobile communication system, comprising the step of:

preparing a buffer for a contention based uplink and a buffer for a regular uplink HARQ, as a buffer for a HARQ.

6. A processing method at a mobile station device communicating with a base station device in a mobile communication system, comprising the steps of:

obtaining a maximum number of times of retransmission of a HARQ for a contention based uplink and a maximum number of times of retransmission of a HARQ for a regular uplink from the base station device, and

carrying out HARQ processing according to each of said maximum number of times of retransmission.
