摘要： A first network device includes a first PHY device that transfers first data on a first channel between the first network device and a second network device via a base station. The second PHY device receives a first request transmitted on a second channel and in response to receiving the first request, determines whether the first PHY device is receiving the first data. The first request is received from the second network device via an access point and requests permission to send second data. The second PHY device, if the first PHY device is not receiving the first data, determines whether the first PHY device is to receive or transmit the first data in respective periods. The second PHY device transmits a response signal to the second network device, on the second channel, if the first PHY device is not to receive or transmit the first data the respective periods.

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.

摘要： The present disclosure includes systems and techniques relating to wireless devices. A described technique includes determining wireless resource allocations (e.g., spatial wireless channel allocations, downlink slot assignments, uplink slot assignments, and frequency sub-band assignments that correspond respectively to frequency sub-bands of a frequency band) in a time domain, a spatial wireless channel domain, and a frequency domain to coordinate communications with wireless devices. The technique further includes generating and transmitting information in one or more frames that directs wireless communications based on the wireless resource allocations. The information can be configured to cause the devices to receive respective data in downlink slots via spatial wireless channels in accordance with the wireless resource allocations, and to cause the devices to transmit, concurrently, respective acknowledgement indications, in response to the respective data, in uplink slots in accordance with the wireless resource allocations. The acknowledgement indications can be assigned to different frequency sub-bands.

摘要： A first device including a controller and a transmitter. The controller generates a communication schedule based on a profile. The communication schedule specifies a first duration to transfer data between the first device and a second device using a wireless protocol. The profile indicates (i) a start time, (ii) a duration, and (iii) a periodicity of communication between the first device and the second device using the wireless protocol. The transmitter transmits the communication schedule via a message from the first device to the second device using the wireless protocol. The message is a pre-defined message specified by the wireless protocol. The pre-defined message is dedicated to communicate information about interference present in an operating environment of the first device and the second device.

摘要： Systems and techniques relating to wireless communications are described. A described technique includes determining a primary access category for a transmission opportunity (TXOP) to transmit data to a primary wireless communication device based on a first back-off timer associated with the primary access category; determining a secondary access category for the TXOP to transmit data to a secondary wireless communication device; and transmitting, during the TXOP, spatially steered streams that concurrently provide separate data to respective devices comprising the primary and the secondary device. The technique can include controlling a contention window and a second back-off timer associated with the secondary access category, where the second back-off timer is not penalized for a communication failure associated with the primary access category or the secondary access category during the TXOP, and where the contention window is not penalized for the communication failure associated with the secondary access category during the TXOP.
