Wireless communication device, method, and system for wireless connection using a packet including transmission number

A wireless communication device that receives data transmitted using a packet including a transmission number from another wireless communication device that performs wireless connection, the wireless communication device comprising:

• a receiver configured to receive a packet including the data;
• and
• a processer configured to:
• perform first reception processing when the received packet is transmitted in a first transmission mode in a first layer that manages a data link in the wireless connection used when the data is first data of which the transmission condition indicating a condition related to transmission of the data is a first transmission condition in a PDCP (Packet Data Convergence Protocol) layer, wherein the first transmission mode corresponds to a first logical channel of a first logical channel number;
• and
• perform second reception processing when the received packet is transmitted in a second transmission mode in the first layer when the data is second data of which the transmission condition is a second transmission condition, wherein the second transmission mode corresponds to a second logical channel of a second logical channel number,
• wherein the first layer is a lower layer of the PDCP layer.

A wireless communication system comprising:

• a first wireless communication device;
• and
• a second wireless communication device configured to transmit data to the first wireless communication device that performs wireless connection using a packet including a transmission number, wherein
• the second 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 to classify the data as second data when the transmission condition of the data is a second transmission condition different from the first transmission condition in a PDCP (Packet Data Convergence Protocol) layer;
• and
• a transmitter configured to:
• select a logical channel to transmission of the data from multiple channels according to the classification in the PDCP layer;
• and
• transmit the data using the logical channel,
• wherein the transmitter is further configured to:
• select, when the data is the first data, a first transmission mode in a first layer that manages a data link in the wireless connection, and a first logical channel of a first logical channel number as the logical channel, the first logical channel number corresponding to the first transmission mode;
• and
• select, when the data is the second data, a second transmission mode in the first layer, and a second logical channel of a second logical channel number as the logical channel, the second logical channel number corresponding to the second transmission mode, and
• the first wireless communication device includes:
• a receiver configured to receive a packet including the data;
• and
• a processer configured to perform first reception processing when the received packet is transmitted in the first transmission mode and performs second reception processing when the received packet is transmitted in the second transmission mode,
• wherein the first layer is a lower layer of the PDCP layer.
