Abstract: A method may include determining, by an access point, which stations among multiple stations are permitted access to a wireless communication medium in a subsequent uplink frame. The method may also include broadcasting an uplink map to the stations, where the uplink map identifies a first station of the multiple stations as permitted access to the wireless communication medium. The uplink map may also identify an allocation of the subsequent uplink frame for the first station. The method may also include, during the allocation of the subsequent uplink frame allocated to the first station, receiving: an acknowledgment (ACK) of downlink data transmitted to the first station, uplink data, a resource allocation request from the first station requesting access to a second subsequent uplink frame, and/or combinations thereof.

Abstract: A transceiver (103, 228) communicates with a station (105a, 105b) in a first network (101) and includes a detection circuit (236) that detects a signal in a second network (109) from a second transceiver (111, 228) to a second station (105, 105d). A coverage area of the second network (109) overlaps the first network (101). The detection circuit (236) determines a second symbol alignment of the signal in the second network (109) based on a preamble. The transceiver (103, 228) includes a precoding determination circuit (237) coupled to transmit chains (230) that determines a precoding matrix and the first symbol alignment. The first symbol alignment is synchronized with the second symbol alignment. The transmit chains (230) pre-code a signal in the first network (101) using the precoding matrix and align symbols of the signal in the first network (101) according to the first symbol alignment.
