Signaling for multi-dimension wireless resource allocation
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.
