Abstract: A method may be provided. One or more packets from a client may be received, in a block based modulation environment, at one or more switchable antennas of an access point. The access point may have a plurality of switchable antennas. Each switchable antenna may have an antenna state. The plurality of switchable antennas may be switched among such that at least five of the antenna states are sampled. Angle of arrival of the client may be calculated based on the at least five of the antenna states.

Abstract: A method for scheduling a random access trigger frame (RA TF) in a wireless LAN includes determining whether a scheduled access (SA) TF is scheduled during a beacon interval (BI) beginning with a next beacon; determining whether one of, a first weighted average of a sum of (i) a number of clients whose respective buffer status reports (BSRs) have been successfully received (NSUCC) and (ii) a number of clients whose respective BSRs collided with one another (NCOL) is greater than a first threshold, or a second weighted average of an active number of UL OFDMA enabled HE users sending SU uplink traffic (NSU) is greater than the first threshold; when either weighted average is greater than the first threshold, allocating a predetermined number of RA RUs along with at least one SA RU in a buffer status report poll (BSRP) TF and scheduling the BSRP TF for transmission.

Abstract: Techniques for uplink scheduling in a wireless network are disclosed. A wireless access point (AP) receives, from a wireless station (STA), a buffer status report (BSR) reflecting data accumulated at the STA for uplink to the AP. The AP identifies, based on the BSR, a scheduling mode under which the data was accumulated at the STA. The AP schedules an uplink parameter for the STA, based on the identified scheduling mode. The uplink parameter relates to at least one of: (i) an uplink transmission for the STA or (ii) a buffer status poll for the STA. The AP transmits, to the STA, an allocation relating to the scheduled uplink parameter for the STA.

Abstract: Techniques for dynamic bandwidth expansion are provided. A first set of channel quality metrics is collected, by an access point (AP) communicating using a first bandwidth, for an expanded bandwidth beyond the first bandwidth. A second set of channel quality metrics for the expanded bandwidth is received from one or more stations. An available portion of the expanded bandwidth is then determined based on the first and second sets of channel quality metrics. Communication with the one or more stations is initiated using the available portion of the expanded bandwidth.

Abstract: A method includes receiving, at an access point, a buffer status report from a device wirelessly connected to the access point. The buffer status report indicates a queue depth of the device and a head of line delay for the device. The method further includes scheduling uplink resources at the access point for the device based on the queue depth and the head of line delay.
