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: A wireless communication includes a control circuit and a receiver (RX) circuit. The control circuit obtains indicator information from another wireless communication system, identifies a transmitter (TX) and receiver (RX) packet delivery scenario as one of a packet overlapping scenario and a packet non-overlapping scenario according to the indicator information, and generates RX gain control information in response to the TX and RX packet delivery scenario. The RX circuit refers to the RX gain control information to set an RX gain used for receiving data.

Abstract: Techniques pertaining to multiple-input-multiple-output (MIMO) joint time of arrival (ToA) and angle of arrival (AoA) for Wi-Fi systems in wireless communications are described. An apparatus performs channel estimation to obtain a plurality of multiple-input-multiple-output (MIMO) channel state information (CSI). The apparatus then calculates weighted MIMO CSI and determines a time of arrival (ToA) or the ToA and an angle of arrival (AoA) based at least on the weighted MIMO CSI.

Abstract: Techniques pertaining to dynamic band selection in multi-link operation (MLO) with time averaged specific absorption rate (TA-SAR) information in wireless communications are described. An apparatus determines a resource allocation regarding one or more multi-link operation (MLO) bands. The apparatus then allocates at least one of a transmit (TX) power, a TX duty cycle and a modulation and coding scheme (MCS) rate in wirelessly transmitting in the one or more MLO bands to result in a TA-SAR that is no greater than a predefined limit.
