Abstract: Methods and apparatuses for communicating in a wireless communication network are disclosed. For example, one method includes determining, by a first access point, a polling schedule for communicating with one or more wireless stations on a first wireless communication channel, the polling schedule for a second access point on a second wireless communication channel. The method further includes transmitting, by the first access point, on the first wireless communication channel, transmission information to the one or more wireless stations, wherein the transmission information comprises information for the one or more wireless stations to receive a transmission from the second access point on the second wireless communication channel. The method further includes transmitting, by the first access point, on the first wireless communication channel, one or more packets to at least one of the one or more wireless stations in accordance with the polling schedule.

Abstract: Various aspects are provided for low-latency wireless local area networks. In a aspect, an access point (AP) may select, from a plurality of wireless stations associated with the AP, a wireless station for the AP to poll. Each of the plurality of wireless stations may be configured to transmit on a channel in response to being polled by the AP. The AP may transmit, at a time selected by the AP, a downlink frame including polling information to the wireless station on the channel, the polling information including a permitted duration for the wireless station to access the channel. The AP may monitor during the permitted duration for the AP to receive an uplink transmission from the wireless station on the channel, the uplink transmission from the wireless station being in response to the polling information received by the wireless station.

Abstract: Various aspects are provided for low-latency wireless local area networks (WLANs). An access point (AP) may transmit a downlink pilot signal for synchronization of the AP with one or more wireless stations. The AP may receive an uplink control block synchronized with the downlink pilot signal including a reservation for uplink transmission from a first wireless station of the one or more wireless stations. The reservation may include an uplink pilot signal and a modulated pilot signal and indicate that the first wireless station has traffic for uplink transmission to the AP. The AP may schedule the first wireless station for uplink transmission during a traffic block after the uplink control block. The AP may estimate a wireless channel to the first wireless station based on the pilot signal and the modulated pilot signal. Other low-latency aspects apply to WLANs in which the AP and associated wireless stations are synchronized.
