Abstract: Aspects of the disclosure provide a method, an apparatus, and a non-transitory computer-readable medium for compressing channel state information (CSI). Under the method, a CSI matrix is decomposed, at a first device, into a first vector including a plurality of significant numbers extracted from the CSI matrix. A second vector is generated by multiplying the first vector with a linear operator. A length of the second vector is less than a length of the first vector. The second vector is sent from the first device to a second device along with a number of the plurality of significant numbers in the first vector. The method is implemented in software instructions, and when processing circuitry of the apparatus executes the software instructions, the processing circuitry of the apparatus performs the method. The software instructions are stored in the non-transitory computer-readable medium.

Abstract: In one novel aspect, OFDM RS symbols are configured with zero-power RS occupying either all even subcarrier or all odd subcarriers and the non-zero-power RS occupy all or part of remaining subcarriers. In one embodiment, even component RS symbols and odd component RS symbols are alternatively inserted in data frames with frequency offsets. In one embodiment, the receiver performs a wireless sensing by sampling a final-half duration with phase preprocessing. In one novel aspect, the target distance and velocity are uniquely determined via estimating clustering-range rate during successive CPIs. In one embodiment, the UE performing successive sensing for multiple clusters based on the diamond-shaped RS configuration during N successive CPIs, and a range rate for each cluster, selects a cluster with velocity that matches the calculated range rate, and determines a target distance and velocity based on the selected cluster.

Abstract: A negative charge pump (NCP) with high reliability is shown. A first capacitor is coupled between the power terminal and the ground terminal while in the first state and disconnected from the power terminal and the ground terminal while in the second state. A second capacitor is coupled between the ground terminal and the output terminal of the NCP, wherein while in the second state, the second capacitor is further coupled in parallel with the first capacitor. The first capacitor is coupled to the power terminal and the ground terminal while in the first state through a first switch and the second switch, respectively. When switching from the second state to the first state, the first switch is closed before the second switch.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The method may be performed by a UE. In certain configurations, the UE performs a procedure resulting in a status change of a first pre-configured measurement gap (pre-MG) of a pre-MG activation procedure. The UE determines whether the pre-MG activation procedure collides with or is overlapped with an overlapping gap. In response to determining that the pre-MG activation procedure collides with or is overlapped with the overlapping gap, the UE configures a pre-MG activation delay for the first pre-MG after an end of the overlapping gap, and performs the pre-MG activation procedure in the first pre-MG after the pre-MG activation delay.

Abstract: An apparatus aborts a transmission of a first message of a first type of traffic in a first slot or sub-slot without resuming the transmission in the first slot or sub-slot. The apparatus then stores a payload of the first message. The apparatus later retransmits the payload in full in a second slot or sub-slot that is subsequent the first slot or sub-slot.

The network includes an Access Point (AP) and a plurality of associated stations (STAs). The method includes: detecting a color collision; setting a new BSS color in response to the color collision; configuring an AID update request frame, wherein an updated AID according to the new BSS color is inserted into a subElement Information Element (IE) field of the AID update request frame; and sending the AID update request frame to the plurality of associated STAs to inform the associated STAs of the updated AID.

Abstract: A push-start crystal oscillator (XO), an associated electronic device and a push-start method for performing a start-up procedure of an XO are provided. The push-start XO includes an inverting amplifier and a push-start logic control circuit, wherein the inverting amplifier is coupled to a crystal load. The inverting amplifier generates a first XO signal and a second XO signal. The push-start logic control circuit receives a feedback clock from a phase locked loop (PLL), and generates a phase control clock according to the feedback clock, wherein a push phase and a settle phase are specified by the phase control clock. During the settle phase, the PLL calibrates a frequency of the feedback clock according to the second XO signal. During the push phase, the feedback clock is transmitted to the inverting amplifier in order to increase the amplitude of the first XO signal.

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 control resource set (CORESET) configuration indicating a CORESET, in a slot, in which a control signal is to be transmitted according to a first transmission configuration indication (TCI) state. The UE receives a downlink control information indicating that one or more downlink data channels are to be transmitted according to a second TCI state. The UE determines that the one or more downlink data channels overlap, in time domain, with the CORESET combined with a gap period. The UE performs reception of a smaller portion of the one or more downlink data channels.

Abstract: A user equipment (UE) with N transmit (Tx) antenna elements in a wireless network receives precoding information from a base station. The UE constructs a full-rank complex Hadamard matrix (CHM) of order N using the precoding information. The UE then precodes uplink signal using a precoding matrix composed of one or more columns of the full-rank CHM, and transmits the precoded uplink signal to the base station.
