Abstract

In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE receives a reject message without integrity protection from a Standalone Non-Public Network. The UE adds an identity of the SNPN to a forbidden list for access to localized services. The UE starts a timer. The UE increments an SNPN-specific attempt counter. The UE removes the identity of the SNPN from the forbidden list when the SNPN-specific attempt counter has a value greater than zero and less than a UE implementation-specific maximum value. The UE performs this removal in response to the occurrence of at least one of the following events: an expiry of the timer, the UE is switched off, a Universal Integrated Circuit Card containing a Universal Subscriber Identity Module is removed, or an entry of a list of subscriber data is updated.

Abstract

A voltage controller circuit is provided for dynamic frequency and voltage scaling. The voltage controller circuit receives an error signal indicating a frequency error and a code error. The frequency error indicates a first difference between a target frequency and an actual frequency generated by an oscillator, and the code error indicates a second difference between a minimum code and an actual code with which the oscillator is configured to generate the actual frequency. The minimum code corresponds to a maximum frequency that the oscillator generates for a processor to safely operate under a given voltage. The voltage controller circuit calculates a voltage correction value based on the error signal, a first gain parameter for the frequency error, and a second gain parameter for the code error, and sends a request to a power management circuit to cause an updated voltage to be supplied to the processor.

From the receiver's perspective, a sensing receiver may determine or receive a beam configuration and a reference signal (RS) configuration for a sensing of a target object. The sensing receiver may further perform sweeping(s) of receiving (Rx) beam(s) to receive RS(s) based on the beam configuration and the RS configuration. Then, the sensing receiver may perform the sensing of the target object based on the RSs. From the transmitter's perspective, a sensing transmitter may determine or transmit the beam configuration and the RS configuration for the sensing of the target object, and then perform sweeping(s) of transmitting (Tx) beam(s) to transmit the RS(s) based on the beam configuration and the RS configuration.

Abstract

A controller obtains a first calibrated gain of a residue amplifier. The residue amplifier amplifies a first residue voltage to a voltage corresponding to a first output code of a second stage of the pipelined ADC. The first residue voltage is output from a capacitive digital-to-analog converter (CDAC) of a first stage of the pipelined ADC. The controller obtains a second calibrated gain of the residue amplifier. The residue amplifier amplifies a second residue voltage to a voltage corresponding to a second output code of the second stage of the pipelined ADC. The second residue voltage is output from the CDAC of the first stage of the pipelined ADC. The controller determines a final calibrated gain of the residue amplifier based on the first calibrated gain and the second calibrated gain.

Abstract

A calibration apparatus for calibrating a transceiver includes a loop back circuit, an estimation circuit, and a calibration circuit. The loop back circuit is coupled between a mixer output port of a transmitter (Tx) of the transceiver and a mixer input port of a receiver (Rx) of the transceiver, and applies a sequence of different loop gains. The estimation circuit receives a loop back receiving signal that is output from the Rx under the sequence of different loop gains, and generates at least one estimated value of impairment of the transceiver by performing channel estimation according to at least the loop back receiving signal. The calibration circuit performs calibration upon the transceiver according to the at least one estimated value.
