摘要： Systems and techniques relating to wireless communications are described. A described technique includes obtaining data for a transmission to a wireless communication device. The wireless communication device can be configured to process incoming transmissions based on an aggregate data unit format that specifies signaling for aggregating multiple medium access control (MAC) data units. The technique includes, in a physical (PHY) frame, an aggregate data unit that is based on the data and the aggregate data unit format, the aggregate data unit including a single MAC data unit. The technique includes, in the PHY frame, an indication to signal that the MAC data unit in the aggregate data unit is singular and to cause the wireless communication device to accept the aggregate data unit without a corresponding block acknowledgement agreement.

A described system, for example, includes a device configured to transmit signals, in a frequency band, to the wireless communication devices. The signals can include spatially steered first signals that concurrently provide data to the wireless communication devices. The signals can include one or more second signals to the wireless communication devices to control transmission of responses from the wireless communication devices in the frequency band. The device can monitor for the responses in the frequency band.

摘要： A set of channels is scanned, each channel in the set having a first bandwidth. When it is determined that one or more channels in the set of channels are not being utilized by one or more other wireless communication systems, a channel not being utilized is selected as a primary channel for a wireless communication system. When it is determined that all channels in the set of channels are being utilized by one or more other wireless communication systems, (i) a channel in the set that is aligned with a primary channel of another wireless communication system is selected as the primary channel, or (ii) a channel in the set that overlaps with a secondary channel of another wireless communication system is selected as the primary channel, where the secondary channel of the other wireless communication system has a bandwidth greater than the first bandwidth.
