Google patents power reporting for multi-panel phone transmissions

Patent drawing
Patent drawing from the official filing.

This patent application describes a method for mobile devices to report how much transmission power they have left. It allows the device to send specific power data to the network for different antenna panels and signal waveforms used in uplink communication.

Why it mattersThis is a routine technical improvement for managing signal strength in advanced cellular networks, ensuring efficient data transmission without draining the battery.

In the filing’s own words

This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for a UE to report power headroom associated with dynamic waveform selection for uplink multi-panel transmission. The UE may calculate and report UE-specific power headroom report (PHR) for one or more combinations of waveforms from the multiple antenna panels or panel-specific PHR for one or more waveforms for each panel. The UE ( 102) receives ( 410), from the network entity ( 104), a signaling for configuring at least one power headroom report (PHR) to support dynamic waveform indication in uplink multi-panel transmission. The UE ( 102) transmits ( 1012), to the network entity ( 104), the at least one PHR including a UE-specific PHR or a panel-specific PHR. The UE-specific PHR is associated with at least one waveform combination of the dynamic waveform indication and the panel-specific PHR is associated with at least one waveform of the dynamic waveform indication.

What exactly they claim (claim 1)

1. A method of wireless communication at a user equipment (UE), comprising: receiving, from a network entity, a signaling for configuring at least one power headroom report (PHR) to support uplink multi-panel transmission; and transmitting, to the network entity, the at least one PHR including a UE-specific PHR or a panel-specific PHR based on the signaling, the UE-specific PHR being associated with at least one waveform combination of the uplink multi-panel transmission and the panel-specific PHR being associated with at least one waveform of the uplink multi-panel transmission.
