Abstract

A size of a data packet being transmitted downlink to a specific Wi-Fi 7 client is determined from real-time data traffic. A number of small tones and large tones needed in combination for the data packet transmission, either alone or in combination, is calculated. The combination of small RU tones and large RU tones is allocated to the specific wireless client for use in downlink. The data packet is transmitted downlink to the Wi-Fi 7 client across the combination of small and large RU tones.

Claims (25)

1 . A method in a Wi-Fi 7 access point on a wireless local access network (WLAN), at least partially implemented in hardware, for allocating combinations of resource unit (RU) sizes to one or more Wi-Fi 7 stations based on frame sizes of network traffic, the method comprising:

connecting the one or more Wi-Fi 7 stations to transmit data according to Wi-Fi 7 data format;

determining a size of a data packet being transmitted downlink to a specific Wi-Fi 7 station of the one or more Wi-Fi 7 stations;

calculating a number of small RU tones with a first size and large RU tones with a second size larger than the first size needed in combination for the data packet transmission;

allocating the combination of the small RU tones and the large RU tones to the specific wireless station for use in downlink;

transmitting the data packet downlink to the specific Wi-Fi 7 station across the combination of the small RU tones and the large RU tones, and wherein the small RU tones are allocated for frame sizes under 300 bytes, and the large RU tones are allocated for frame sizes at or greater than 300 bytes.

2 . The method of claim 1 , wherein the step of transmitting the data packet down to the specific Wi-Fi 7 station comprises transmitting the data packet using orthogonal frequency division multiple access (OFDMA).

3 . The method of claim 1 , wherein the combination of the small RU tones and the large RU tones is applied to a group of data packets, and wherein the data packets are distributed using the combination of the small RU tones and the large RU tones.

4 . A non-transitory computer-readable medium in a Wi-Fi 7 access point on a wireless local access network (WLAN), at least partially implemented in hardware, storing instructions that, when executed by a processor, perform a computer-implemented method for allocating combinations of resource unit (RU) sizes to one or more Wi-Fi 7 stations based on frame sizes of network traffic, the method comprising:

connecting the one or more Wi-Fi 7 stations to transmit data according to Wi-Fi 7 data format;

determining a size of a data packet being transmitted downlink to a specific Wi-Fi 7 station of the one or more Wi-Fi 7 stations;

calculating a number of small RU tones with a first size and large RU tones with a second size larger than the first size needed in combination for the data packet transmission;

allocating the combination of the small RU tones and the large RU tones to the specific wireless station for use in downlink; and

transmitting the data packet downlink to the specific Wi-Fi 7 station across the combination of the small RU tones and the large RU tones, and

wherein the small RU tones are allocated for frame sizes under 300 bytes, and the large RU tones are allocated for frame sizes at or greater than 300 bytes.

5 . A Wi-Fi 7 access point on a wireless local access network (WLAN), at least partially implemented in hardware, for allocating combinations of resource unit (RU) sizes to one or more Wi-Fi 7 stations based on frame sizes of network traffic, the Wi-Fi 7 access point comprising:

a processor;

a network interface communicatively coupled to the processor and to the WLAN; and

a memory communicatively coupled to the processor and storing:

a Wi-Fi 7 client module executed by the processor to connect the one or more Wi-Fi 7 stations to transmit data according to Wi-Fi 7 data format; and

an RU tone allocation module executed by the processor to determine a size of a data packet being transmitted downlink to a specific Wi-Fi 7 station,

the RU tone allocation module further executed by the processor to calculate a number of small RU tones with a first size and large RU tones with a second size larger than the first size needed in combination for the data packet transmission, and

the RU tone allocation module further executed by the processor to allocate the combination of the small RU tones and the large RU tones to the specific wireless station for use in downlink, and

wherein the network interface transmits the data packet downlink to the specific Wi-Fi 7 station across the combination of the small RU tones and the large RU tones, and

wherein the small RU tones are allocated for frame sizes under 300 bytes, and the large RU tones are allocated for frame sizes at or greater than 300 bytes.
