LINK ADAPTATION FOR MULTI-USER TRANSMISSION IN 802.11 SYSTEMS |
摘要 |
The embodiments provide a method implemented by a network device for transmitting link adaptation feedback in a Wireless Local Area Network (WLAN) that supports multi-user simultaneous transmission. The method generates and transmits a frame that includes one or more link adaptation feedback values associated with a wireless communications link between the network device and a second network device. In one aspect, the one or more link adaptation feedback values may include a link adaptation feedback value for an entire operation bandwidth of the wireless communications link and a link adaptation feedback value for a given subchannel within the operation bandwidth. In another aspect, link adaptation feedback values for one or more users of a multi-user simultaneous transmission are transmitted in a multi-user acknowledgment (ACK) frame. The embodiments allow for efficient link adaptation in a multi-user simultaneous transmission environment. |

1. A method performed by a network device in a Wireless Local Area Network (WLAN) for transmitting link adaptation information, the method comprising:
generating a frame having a Media Access Control (MAC) header, wherein the MAC header includes a control field including a first bit corresponding to a foremost bit of the control field and a second bit immediately following the first bit, wherein a value of the second bit of the control field indicates whether the control field has a High Efficiency (HE) variant field format, and wherein the control field is to include an indication of one or more link adaptation feedback values associated with a wireless communications link between the network device and a second network device; and transmitting the frame to the second network device through a wireless medium. |
