Abstract
A method and network node for spatial audio assisted radio frequency (RF) beamforming for millimeter wave and terahertz communications in safe mode are disclosed. According to one aspect, a method in a network node includes triggering a wireless device (WD) to transmit at least one acoustic pulse, the triggering being prior to entering a safe mode of operation. The method also includes determining a direction of arrival of the at least one acoustic pulse received from the WD via the microphone array. The method further includes determining an RF beam for communication with the WD based at least in part on the determined direction of arrival. Transmission to the WD may occur on the determined RF beam.
Claims18
A method for beamforming at a network node configured to communicate with a plurality of wireless device, WDs, the network node having a microphone array, the method comprising:
- triggering a WD to transmit at least one acoustic pulse;
- determining a direction of arrival of the at least one acoustic pulse received from the WD via the microphone array;
- determining a radio frequency, RF, beam for communication with the WD based at least in part on the determined direction of arrival, determining an RF beam based at least in part on the determined direction of arrival is performed one or both:
- when a P2 report from the WD is not received within an expected time slot, the P2 report indicating which of a plurality of RF beams is associated with the WD;
- and
- when a P2 report from the WD is deemed to be unreliable, the P2 report indicating which of a plurality of RF beams is associated with the WD;
- and
- transmitting to the WD on the determined RF beam.
A network node configured to communicate with a plurality of wireless device, WDs, the network node comprising:
- a microphone array configured to receive an acoustic pulse from a WD;
- processing circuitry configured to:
- trigger the WD to transmit at least one acoustic pulse;
- determine a direction of arrival of the at least one acoustic pulse received from the WD via the microphone array;
- and
- determine a radio frequency, RF, beam for communication with the WD based at least in part on the determined direction of arrival, determining an RF beam based at least in part on the determined direction of arrival is performed one or both:
- when a P2 report from the WD is not received within an expected time slot, the P2 report indicating which of a plurality of RF beams is associated with the WD;
- and
- when a P2 report from the WD is deemed to be unreliable, the P2 report indicating which of a plurality of RF beams is associated with the WD;
- and a radio interface configured transmit to the WD on the determined RF beam.
