Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, for one or more nodes, capability information regarding a beam tracking capability of a backscattering radio of the UE. The UE may perform beam tracking in accordance with the beam tracking capability. The UE may transmit, for the one or more nodes, beam information based at least in part on the beam tracking. Numerous other aspects are described.

Abstract: A real-time sensing measurement apparatus for a respiratory volume of a tested person includes a controller, a pulse measuring device, a temperature sensor, a flow rate sensor and a storage module. The controller receives an electric signal transmitted by the pulse measuring device, the temperature sensor and the flow rate sensor. The controller, the pulse measuring device, the temperature sensor, the flow rate sensor and the storage module communicate through electric signals. The pulse measuring device, the temperature sensor and the flow rate sensor monitor the respiratory volume of the tested person in real time to obtain test data by the storage module. The different states of the user can be measured in real time by the pulse measuring device, the temperature sensor and the flow rate sensor, and measurement results are rectified in various aspects.
