Abstract: Optimal determination of transmit power level for MLDs in A Wireless Local Area Network (WLAN). An AP can establish synchronous downlink multi-link operations with another MLD. A first link and a second link between the AP and the MLD both operate in a same sub-band. The AP can then determine the same power level for both the first link and second link. After establishing the same power level, the AP can then determine a second power level for the first link and a third power level for the second link. The second power level is greater than the third power level. The AP can then provide the second power level for the first link and the third power level for the second link.

Abstract: An access point allocates resource units within a first channel to mitigate interference from an adjacent second channel. The access point obtains a measure of signal strength corresponding to each wireless device attached to an access point, and assigns, for each wireless device, resource units with a first frequency band of the first channel to mitigate interference with a second frequency band of a second channel adjacent to the first channel. An assignment between a set of resource units and a particular wireless device is based on the measure of signal strength corresponding to the particular wireless device. The access point communicates with the wireless devices on the resource units.

Abstract: In one implementation, a device includes a first set of antennas having a first polarization; and a first radio coupled to the first set of antennas, the combination of the first set of antennas and the first radio supporting a first signal. The device also includes: a second set of antennas having a second polarization, the second polarization is different from the first polarization; and a second radio coupled to the second set of antennas, the combination of the second set of one or more antennas and the second radio supporting a second signal, the second signal is independent of the first signal. In some implementations, the first radio is operated according to a first power level in order to establish the first coverage area, and the second radio is operated according to a second power level in order to establish the second coverage area.
