Abstract: A wireless communication calibration system has a radio chipset, an analog circuit set, and a calibration path. The radio chipset has a transmitter and a receiver. The analog circuit set is external to the radio chipset and coupled to the transmitter, and receives an output signal of the transmitter and generates a transmission signal according to the output signal. The calibration path is external to the radio chipset and coupled to the analog circuit set, and guides an input signal to the receiver, wherein the input signal is derived from the transmission signal, and a first delay is calculated after the input signal is received by the receiver.

Abstract: Techniques pertaining to low-power enhanced multi-link single radio (EMLSR) listen in wireless communications are described. A first multi-link device (MLD) reduces power consumption while supporting a latency-sensitive application by performing certain operations. The first MLD first listens at a lower power in a narrower bandwidth to receive an initial physical-layer protocol data unit (PPDU) from a second MLD as part of a frame exchange. In response to receiving the initial PPDU, the first MLD switches from the narrower bandwidth to a wider bandwidth to complete the frame exchange with the second MLD in the wider bandwidth. In reducing the power consumption, the first MLD reduces its power consumption to the lower power when operating in the narrower bandwidth compared to a higher power used by the first MLD when operating in the wider bandwidth.
