摘要： A method of generating packets for transmission in a wireless communication system. The method comprises generating a data packet and generating a null data packet. Generating the data packet includes generating a data packet signal (SIG) field including a first data packet SIG subfield indicating a first physical layer (PHY) parameter to a receiving device. Generating the data packet also includes generating a data field. Furthermore, generating the null data packet includes generating a null data packet SIG field. The null data packet SIG field includes a first null data packet SIG subfield indicating a second PHY parameter to a receiving device. The data packet SIG field excludes any SIG subfield indicating the second PHY parameter to a receiving device, and (ii) the null data packet SIG field excludes any SIG subfield indicating the first PHY parameter to a receiving device.

摘要： The present disclosure includes systems and techniques relating to wireless communications. 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. The device can control, based on a lack of reception of an expected response, a transmission of a third signal in the frequency band to prevent a transmission from another wireless communication device different than the wireless communication devices. The third signal can include information to reschedule a transmission of a response from a wireless communication device.

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.
