To this end, the present invention provides a wireless communication method for a terminal including transmitting a trigger frame indicating simultaneous uplink data transmission of multi-users, receiving uplink data transmitted by a plurality of terminals in response to the trigger frame, and transmitting a block acknowledgement for the plurality of terminals having transmitted the uplink data, and a wireless communication terminal using the same. ## Claims ### Claim 1 A wireless communication method of a wireless communication terminal, the method comprising: receiving a trigger frame, from an access point (AP), soliciting uplink transmission to one or more terminals, wherein the trigger frame includes an association identifier (AID) field used for allocating different types of resources depending on a type of the trigger frame; performing the uplink transmission to the AP using resource indicated by an AID value of the AID field included in the trigger frame; and receiving an acknowledgment frame in response to the uplink transmission from the AP, wherein the AID value indicated by the AID field is selected within different ranges depending on the type of the trigger frame. ### Claim 2 (depends on 1) The wireless communication method of claim 1, wherein the trigger frame is used to allocate only designated resources (Dedicated Resources) or is used to allocate the designated resources or a random access resource that is not allocated to a specific terminal. ### Claim 3 (depends on 2) The wireless communication method of claim 2, wherein the trigger frame includes at least one first AID for allocating only the designated resource when the trigger frame is used to allocate only the designated resource, and wherein each of the at least one first AID is set to one of values within a preset range. ### Claim 4 (depends on 3) The wireless communication method of claim 3, wherein the first range includes “1” and “2006”. ### Claim 5 (depends on 2) The wireless communication method of claim 2, wherein the trigger frame includes at least one of at least one first AID for allocating only the designated resources or at least one second AID for allocating the random access resource when the trigger frame is used to allocated the designated resources or the random access resource that is not allocated to the specific terminal, wherein each of the at least one first AID is set to one of values within a preset range, and wherein each of the at least one second AID is set to a specific value that is not included in the preset range. ### Claim 6 (depends on 1) The wireless communication method of claim 1, wherein the AID value is selected within a first range when the type of trigger frame is a first type. ### Claim 7 (depends on 1) The wireless communication method of claim 1, wherein the AID value is selected within a second range when the type of trigger frame is a second type. ### Claim 8 A wireless communication terminal comprising: a transceiver; and a processor, wherein the processor is configured to: receive a trigger frame, from an access point (AP), soliciting uplink transmission to one or more terminals, wherein the trigger frame includes an association identifier (AID) field used for allocating different types of resources depending on a type of the trigger frame, perform the uplink transmission to the AP using resource indicated by an AID value of the AID field included in the trigger frame, and receive an acknowledgment frame in response to the uplink transmission from the AP, and wherein the AID value indicated by the AID field is selected within different ranges depending on the type of the trigger frame. ### Claim 9 (depends on 8) The wireless communication terminal of claim 8, wherein the trigger frame is used to allocate only designated resources (Dedicated Resources) or is used to allocate the designated resources or a random access resource that is not allocated to a specific terminal. ### Claim 10 (depends on 3) The wireless communication terminal of claim 3, wherein the trigger frame includes at least one first AID for allocating only the designated resource when the trigger frame is used to allocate only the designated resource, and wherein each of the at least one first AID is set to one of values within a preset range. ### Claim 11 (depends on 10) The wireless communication terminal of claim 10, wherein the preset-first range includes “1” and “2006”. ### Claim 12 (depends on 3) The wireless communication terminal of claim 3, wherein the trigger frame includes at least one of at least one first AID for allocating only the designated resources or at least one second AID for allocating the random access resource when the trigger frame is used to allocated the designated resources or the random access resource that is not allocated to the specific terminal, wherein each of the at least one first AID is set to one of values within a preset range, and wherein each of the at least one second AID is set to a specific value that is not included in the preset range. ### Claim 13 (depends on 8) The wireless communication terminal of claim 8, wherein the AID value is selected within a first range when the type of trigger frame is a first type. ### Claim 14 (depends on 8) The wireless communication terminal of claim 8, wherein the AID value is selected within a second range when the type of trigger frame is a second type.
