Abstract

A wireless communication device that transmits data to another wireless communication device that performs wireless connection using a packet including a transmission number, the wireless communication device includes, a controller configured to classify the data as first data when a transmission condition indicating a condition related to transmission of the data is a first transmission condition and classifies the data as second data when the transmission condition of the data is a second transmission condition different from the first transmission condition, and a transmitter configured to transmit the data in a first transmission mode in a layer related to the wireless connection when the data is the first data and transmits the data in a second transmission mode in a layer related to the wireless connection when the second data is second data.

First claim

What is claimed is:

1. A wireless communication device that transmits data to a second wireless communication device using a packet including a transmission number, the wireless communication device comprising:
a controller configured to control a data transferring of a data link layer, the data transferring including a classification process that classifies, according to a process of higher layer of an RLC (Radio Link Control) layer that is included a second layer which manages data link for wireless connection, the data as first data or second data, the data being classified as the first data when a transmission condition indicating a condition related to transmission of the data is a first transmission condition, the data being classified as the second data when the transmission condition of the data is a second transmission condition different from the first transmission condition; and
a transmitter configured to:
when the data is the first data, select a first logical channel of a first logical channel number from a plurality of the logical channels and transmit the data, and
when the data is the second data, select a second logical channel of a second logical channel number from the plurality of the logical channels and transmit the data, wherein
the first logical channel number corresponds to a first transmission mode in the RLC layer and indicates to the second wireless communication device that the data is transmitted using the first transmission mode, and
the second logical channel number corresponds to a second transmission mode in the RLC layer and indicates to the second wireless communication device that the data is transmitted using the second transmission mode.

2. The wireless communication device according to claim 1 , wherein
the first transmission mode is a transmission mode in which the second wireless communication device is caused to execute processing corresponding to data included in a packet received in advance by the second wireless communication device when a packet of a transmission number successive to the received packet is received and the second wireless communication device is not caused to execute the processing corresponding to the data included in the packet received in advance by the second wireless communication device until the packet of the transmission number successive to the packet received in advance is received when a packet of a transmission number that is not successive to the packet received in advance by the second wireless communication device is received, and
the second transmission mode is a transmission mode in which the second wireless communication device is caused to execute the processing corresponding to the data included in the packet received in advance by the second wireless communication device when a packet of a transmission number that is successive to or not successive to the packet received in advance by the second wireless communication device.

3. The wireless communication device according to claim 2 , wherein
the processing corresponding to the data is processing of delivering the data to an application program which uses the data and is included in the second wireless communication device.

4. The wireless communication device according to claim 1 , wherein
the first transmission condition is an allowable latency indicating a latency allowed for transmitting the data, and
the second transmission condition is an allowable latency shorter than the first transmission condition.

5. The wireless communication device according to claim 1 , wherein
the second data is data with higher degree of urgency than the first data.

6. The wireless communication device according to claim 1 , wherein
the first transmission mode is a transmission mode in which the second wireless communication device is requested to transmit an acknowledgement indicating that a packet has been received, and
the second transmission mode is a transmission mode in which the second wireless communication device is not requested to transmit the acknowledgement.

7. The wireless communication device according to claim 6 , wherein
the first transmission mode is an AM (Acknowledged Mode), and
the second transmission mode is a UM (Unacknowledged Mode).

8. The wireless communication device according to claim 1 , wherein
the transmitter incorporates information indicating that data is the second data in a packet that transmits the data in an uppermost layer among a plurality of layers included in the second layer.

9. A wireless communication device that receives data that is transmitted using a packet including a transmission number from a first wireless communication device, the wireless communication device comprising:
a receiver configured to receive the packet including the data at a data link layer; and
a processor configured to:
control to perform a first reception process corresponding to a first transmission mode in an RLC (Radio Link Control) layer included in the data link layer when the data is received via a first logical channel corresponding to a first logical channel number, and
control to perform a second reception process corresponding to a second transmission mode in the RLC layer included in the data link layer when the data is received via a second logical channel corresponding to a second logical channel number, wherein
the first logical channel number corresponds to the first transmission mode, and
the second logical channel number corresponds to the second transmission mode.

10. The wireless communication device according to claim 9 , wherein
the first reception process is a process in which executes processing corresponding to data included in a packet received in advance when a packet of a transmission number successive to the received packet is received and not execute the processing corresponding to the data included in the packet received in advance until the packet of the transmission number successive to the packet received in advance is received when a packet of a transmission number that is not successive to the packet received in advance, and
the second reception process is a process in which the executes the processing corresponding to the data included in the packet received in advance when a packet of a transmission number that is successive to or not successive to the packet received in advance.

11. A wireless communication system comprising:
a first wireless communication device configured to transmit data using a packet including a transmission number; and
a second wireless communication device configured to receive the data, wherein
the first wireless communication device includes:
a controller configured to control a data transferring of a data link layer, the data transferring including a classification process that classifies, according to a process of higher layer of an RLC (Radio Link Control) layer that is included a second layer which manages data link for wireless connection, the data as first data or second data, the data being classified as the first data when a transmission condition indicating a condition related to transmission of the data is a first transmission condition, the data being classified as the second data when the transmission condition of the data is a second transmission condition different from the first transmission condition; and
a transmitter configured to:
when the data is the first data, select a first logical channel of a first logical channel number from a plurality of the logical channels and transmit the data, and
when the data is the second data, select a second logical channel of a second logical channel number from the plurality of the logical channels and tra
