Apparatus and method for operating resource in wireless local area network system supporting multi-user transmission scheme
The present disclosure relates to a pre-5 th -Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4 th -Generation (4G) communication system such as a Long Term Evolution (LTE). A method for operating a resource in a first device in a wireless local area network (WLAN) system supporting a multi-user transmission scheme is provided. The method includes determining a number of resource allocation request messages acceptable at a timing point; and transmitting information related to the number of resource allocation request messages, wherein a resource allocation request message is acceptable if the first device is capable of allocating a resource to a second device that transmits the resource allocation request message at the timing point.
1. A method of a first device in a wireless local area network (WLAN) system supporting a multi-user transmission scheme, the method comprising:
transmitting a signal including information related to a number of resource allocation request messages to be accepted by the first device at a timing point and information related to each of second devices in which a resource allocation request message is to be transmitted at the timing point,
wherein the resource allocation request message is to be accepted if the first device is capable of allocating a resource to each of the second devices at the timing point.
2. The method of claim 1 , wherein a time interval during which each of other second devices different from the second devices waits until an acknowledgement (ACK) signal is received in each of the other second devices is set in each of the other second devices after the signal is received in each of the other second devices.
3. A method of a second device in a wireless local area network (WLAN) system supporting a multi-user transmission scheme, the method comprising:
receiving a signal including information related to a number of resource allocation request messages to be accepted by a first device at a timing point and information related to each of second devices in which a resource allocation request message is to be transmitted at the timing point,
wherein the resource allocation request message is to be accepted if the first device is capable of allocating a resource to each of the second devices at the timing point.
4. The method of claim 3 , further comprising:
setting a time interval during which the second device waits until an acknowledgement (ACK) signal is received in the second device.
5. A first device in a wireless local area network (WLAN) system supporting a multi-user transmission scheme, the first device comprising:
a transceiver configured to transmit a signal including information related to a number of resource allocation request messages to be accepted by the first device at a timing point and information related to each of second devices in which a resource allocation request message is to be transmitted at the timing point,
wherein the resource allocation request message is to be accepted if the first device is capable of allocating a resource to each of the second devices at the timing point.
6. The first device of claim 5 , wherein a time interval during which each of other second devices different from the second devices waits until an acknowledgement (ACK) signal is received in each of the other second devices is set in each of the other second devices after the signal is received in each of the other second devices.
7. A second device in a wireless local area network (WLAN) system supporting a multi-user transmission scheme, the second device comprising:
a transceiver configured to receive a signal including information related to a number of resource allocation request messages to be accepted by a first device at a timing point and information related to each of second devices in which a resource allocation request message is to be transmitted at the timing point,
wherein the resource allocation request message is to be accepted if the first device is capable of allocating a resource to each of the second devices at the timing point.
8. The second device of claim 7 , further comprising:
a controller is configured to set a time interval during which the second device waits until an acknowledgement (ACK) signal is received in the second device.
