1. An access point device, comprising:
a transceiver configured to transmit and receive wireless signals to and from a plurality of
client station devices that form a basic service set (BSS) with the access point device; and
a processing circuit configured to determine whether the BSS should operate in a scheduled operation mode or a non-scheduled operation mode, and announce the determined operation mode to the client station devices, wherein transmissions between the access point device and the BSS are scheduled in the scheduled operation mode, and the transmissions between the access point device and the BSS are not scheduled in the non-scheduled operation mode, wherein a client station device of the BSS enters a low priority enhanced distributed channel access (EDCA) state to decrease chances to transmit when the client station device is scheduled by the access point device in multi-user transmissions and wherein a client station device of the BSS enters a high priority enhanced distributed channel access (EDCA) state to increase chances to transmit when the client station device is not scheduled by the access point device in multi-user transmissions.
