Wireless communication terminal and wireless communication method for transmitting uplink by multiple users
The present invention relates to a wireless communication terminal and a wireless communication method for efficiently scheduling simultaneous uplink transmissions of a plurality of terminals. To this end, provided are a wireless communication terminal, the terminal including: a transceiver; and a processor, wherein the processor is configured to: generate an uplink packet, wherein a predetermined field of a MAC header of the uplink packet indicates information on uplink data of the terminal, and transmit the generated uplink packet to a base wireless communication terminal, and a wireless communication method using the same.
1. A wireless communication terminal, the terminal comprising:
a transceiver; and
a processor,
wherein the processor is configured to:
generate an uplink packet, wherein a predetermined field of a MAC header of the uplink packet indicates information on uplink data of the terminal, and
transmit, through the transceiver, the generated uplink packet to a base wireless communication terminal,
wherein the predetermined field of the MAC header individually indicates size information of uplink data corresponding to a first access class set and size information of uplink data corresponding to a second access class set.
2. The wireless communication terminal of claim 1 , wherein the information on uplink data of the terminal includes buffer status information of the terminal.
3. The wireless communication terminal of claim 2 , wherein the buffer status information of the terminal includes at least one of an access class of the uplink data and size information of the uplink data.
4. The wireless communication terminal of claim 1 , wherein information of the predetermined field of the MAC header is used for multi-user uplink transmission scheduling of the base wireless communication terminal.
5. The wireless communication terminal of claim 1 , wherein information of the predetermined field of the MAC header is used for updating a multi-user uplink information queue of the base wireless communication terminal.
6. The wireless communication terminal of claim 1 , wherein the information on uplink data of the terminal is transmitted with an ACK corresponding to a downlink packet of the base wireless communication terminal.
7. The wireless communication terminal of claim 1 , wherein the first access class set and the second access class set are different from each other.
8. A wireless communication method of a wireless communication terminal, the method comprising:
generating an uplink packet, wherein a predetermined field of a MAC header of the uplink packet indicates information on additional uplink data of the terminal; and
transmitting the generated uplink packet to a base wireless communication terminal,
wherein the predetermined field of the MAC header individually indicates size information of uplink data corresponding to a first access class set and size information of uplink data corresponding to a second access class set.
9. The wireless communication method of claim 8 , wherein the information on uplink data of the terminal includes buffer status information of the terminal.
10. The wireless communication method of claim 9 , wherein the buffer status information of the terminal includes at least one of an access class of the uplink data and size information of the uplink data.
11. The wireless communication method of claim 8 , wherein information of the predetermined field of the MAC header is used for multi-user uplink transmission scheduling of the base wireless communication terminal.
12. The wireless communication method of claim 8 , wherein information of the predetermined field of the MAC header is used for updating a multi-user uplink information queue of the base wireless communication terminal.
13. The wireless communication method of claim 8 , wherein the information on uplink data of the terminal is transmitted with an ACK corresponding to a downlink packet of the base wireless communication terminal.
14. The wireless communication method of claim 8 , wherein the first access class set and the second access class set are different from each other.
