    Abstract: Implementations of the present disclosure relate to resource unit (RU) assignment to combat frequency selective fading. A method comprises determining, at an access point (AP), a plurality of channel qualities of a plurality of resource units (RUs) for a client. The plurality of RUs are configured to be available for communications with a plurality of clients comprising the client. The method further comprises determining, from the plurality of RUs, a target RU for the client based at least in part on the plurality of channel qualities. The target RU is to be used by the client for a following transmission with the AP. A target RU with good channel quality will be assigned to the client, thus the transmission and overall system performance will be enhanced.

    Abstract: In embodiments of the present disclosure, a method is provided for managing a communication channel between a first communication unit and a second communication unit in an AP. At the first communication unit, a request is transmitted to the second communication unit for reserving a communication channel. Here, the second communication unit is associated with a Wi-Fi network that is different from a network type associated with the first communication unit, and the first and second communication units share a band of the communication channel. A response for reserving the communication channel is received from the second communication unit. In accordance with a determination that the response indicates the communication channel has been reserved for a time duration, data is transmitted at the first communication unit within the time duration on the communication channel. Therefore, conflicts between the first and second communication units in the AP may be reduced.

    Abstract: Examples of techniques for Association Identifier (AID) assignment are disclosed. In an example, a controller managing an AP may allocate a set of numbers for AID assignment to clients connecting to VAPs in a multiple BSSID set of the AP. The controller may configure the AP to assign AIDS to non-Multi-Link (non-ML) clients from a first subset of the set based on a first monotonic sequence and assign AIDS to ML clients from a second subset of the set based on a second monotonic sequence. The AP may receive an association request from a client to associate with a VAP of the multiple BSSID set, determine whether Multi-Link operation (MLO) is enabled for the client, and in response to determining that MLO is disabled for the client device, assign a first AID to the client from the first subset based on the first monotonic sequence.

    Abstract: In embodiments of the present disclosure, there is provided an approach for channel sounding. According to embodiments of the present disclosure, if the CSI change rate exceeds a first threshold, the AP may disable the beamforming. If the CSI change rate does not exceed the first threshold but exceeds a second threshold below the first threshold, the AP may perform the channel sounding at a first time interval. Otherwise, if the CSI change rate does not exceed the second threshold, the AP may perform the channel sounding at a second time interval. Embodiments of the present disclosure provide an effective way for channel sounding.

    Abstract: Embodiments of the present disclosure relate to automatic antenna beam alignment. A method comprises determining first position-related information indicating a first location and a first orientation of a first communication device. The first communication device comprises a plurality of antenna sectors configured for generating respective directional beams. The method also comprises receiving, from a second communication device, second position-related information indicating a second location and a second orientation of the second communication device. The method also further comprises selecting a subset of the plurality of antenna sectors based on the first and the second position-related information; and causing the first communication device to perform beamforming training with the second communication device using the selected subset of antenna sectors. A decreased number of antenna sectors are scanned during the beamforming training, which can reduce the time overhead and facilitate the devices to find the best beam efficiently.

    Abstract: An example method of controlling a wireless access point may include causing the wireless access point to identify any groupings of contiguous non-protocol FFT bins of a wireless channel in which all of the non-protocol FFT bins in the grouping have respective signal strength values exceeding a first threshold, and a bandwidth of the grouping does not exceed a second threshold. The method may also include causing the wireless access point to identify any resource units of the wireless channel that overlap with any of the identified groupings. The method may also include causing the wireless access point to, in allocating the resource units to client devices for an OFDMA communication, skip the identified resource units.

    Abstract: Examples described herein provide multi-band directional scanning. Examples may include receiving, by a first radio of a first network device operating at a first frequency band below the millimeter-wave (mmWave), a probe request from a second network device indicating a protocol and a particular sector receiving direction of the second network device, and in response to the protocol indicated by the probe request, transmitting, by a second radio of the first network device operating at a second frequency band within the mmWave, a probe response in each of one or more sector transmitting directions, wherein the second network device receives one or more probe responses in the particular sector receiving direction.
